Abstract: A trimmer head includes a rotatable housing connectable to a trimmer line spool rotatably supported by the housing and a locking mechanism for locking the trimmer line spool to the housing with a locking force. The locking mechanism is arranged to be moved from a locked to an unlocked position when a rotation speed of the trimmer head is increased above an operating speed. The increased rotation speed causes a releasing force greater than the locking force. In the unlocked position, the locking mechanism releases the trimmer line spool from the housing such that the trimmer line spool is movable and a trimmer line spooled around the spool is released and pulled out by a centrifugal force caused by the rotation of the trimmer head, allowing feed of the trimmer line.

Abstract: A cutter assembly for a hedge trimmer includes lower and upper cutters in a longitudinal structure having a longitudinal axis and overlapping each other along a first direction perpendicular to the longitudinal axis. The lower and upper cutters slide relative to each other along a second direction parallel to the longitudinal axis. Each of the lower and upper cutters has a cutter main body and a plurality of cutting edges protruding from the cutter main body along a third direction perpendicular to the longitudinal axis. The cutter main body of the lower cutter has an inner circumferential face enclosing an elongated hole. The elongated hole penetrates the cutter main body. The inner circumferential face is configured with first to fourth sides. The first side of the inner circumferential face has a protrusion protruding toward the second side of the inner circumferential face.

Abstract: The device is a tool holder capable of holding various types of tools. The device uses a cam lock mechanism designed to quickly attach and detach the tool from the tool holder. The cam lock cinches down on the shank of the tool, which virtually eliminates any play or movement during hard use. To replace the tool, the user deactivates the cam lock by pressing upward on the cam lever. In turn, the cam lobe rotates and slides out of a recessed portion of the shank. This unlocks the shank and allows the user to freely slide the tool out of the tool holder. To prevent the cam lock from accidentally unlocking during normal use, the device also incorporates a safety lock mechanism. The safety lock requires the user to first press and hold down a button next to the cam lock before disengaging the cam lock mechanism.

Abstract: Pruning shears include a housing having a motor portion and a handle portion. A motor is disposed within the motor portion of the housing, and a trigger assembly is disposed within the housing portion. The trigger assembly is operable to control the motor. The trigger assembly includes a trigger and a trigger lock. The trigger lock prevents actuation of the trigger until the trigger lock is depressed.

Abstract: A handle holder of a blade tool is provided for retracting a blade to be concealed in a blade cavity of the handle holder and extending the blade out of the blade cavity for use due to gravity. The handle holder includes a locker device, a first holder member and a second holder member pivotally connected with the first holder member to define a blade cavity therebetween for receiving a blade holder slidably therein between a locking position, an unlocking position and a detaching position. The locker device is able to selectively lock relative positions of the first holder member and the second holder member with respect to each other so as to selectively lock the handle holder in the enclosing condition and the operable condition.

Abstract: Personal care devices such as hair removal devices or electric shavers include a working head, a handle, an adjustment device, and a hazard determination device. The working head is configured for applying a personal care treatment to a body surface. The handle is attached to the working head to enable a user to manually move the working head along the body surface. The adjustment device is configured to adjust various settings of the working head. The hazard determination device sends a hazard signal to the adjustment device when a hazard condition to the personal care device is recognized, such as a freefall condition, high temperature, or low battery charge. Example hazard determination devices may include acceleration sensors, gyrosensors, temperature sensors, or voltage detectors. The adjustment device responds to the hazard signal by adjusting a setting of the working head into a safe harbor setting to protect the personal care device.

Abstract: A hedge trimmer includes a blade assembly, a power assembly, a battery pack, a connecting rod and a handle assembly. A first end of the connecting rod is fixedly connected with the power assembly and a second end of the connecting rod is connected with a battery pack cavity. The battery pack is mounted in the battery pack cavity, and the power assembly accounts for less than 46% of a weight of the hedge trimmer. The disclosure reduces a weight of the power assembly at a front end through placing the battery pack behind, and a hedge trimmer may not turn its head, which shortens an overall length requirement of the hedge trimmer. Therefore, a weight of the hedge trimmer is reduced, and a structure of the hedge trimmer is compact.

Abstract: A trimmer head for vegetation trimming and cutting machines. The trimmer head including a housing; a cutting blade; a cutting blade shield with a plurality of through-openings; and a blowing air assembly that has at least one blowing nozzle pointing to the blade shield openings such that, in operation, a blowing air flow is directed from the blowing nozzle towards the blade shield openings.

Abstract: Variable force compound gear lopper devices and methods that produce a pinching effect of the handles which comes into play only after the wood, branch, is in the jaws. Once the wood, such as a branch, is in the jaws it causes a countering force which allow the new handle arrangement to cause the frame to rotate slightly on the hook side against the work opposite the cutting blade. So, in effect there is a double compound action against the work. A true double compound pinching effect against the work from both sides of the lopper. With the old version the frame is static and the only action is from the blade side. The variable force lopper has an upper handle; a lower handle connected by a cutting head with upper and lower arms therebetween, with an upper jaw and a lower jaw; and having a slot in the lower arm for the upper jaw.

Abstract: A shaving unit (12) has an assembly of at least two rotary hair-cutting units (13) and a supporting member (26) to which the hair-cutting units are connected. The assembly of the hair-cutting units and the supporting member can move linearly relative to a base portion (20) between a first, retracted, position and a second, extended, position. The supporting member is biased by a spring member (30) away from the base portion. The hair-cutting units each have an individual hair-collecting chamber and they are individually pivotable relative to the supporting member. The base portion comprises a coupling structure (44) by means of which the shaving unit can be releasably coupled to the main housing (15) of a shaving device.

Abstract: A shaving razor apparatus having a handle with a blade-carrying head at one end and a rotary assembly at the opposite end. The rotary assembly enables controlled pivoting of the handle and head in response to pressure. It includes a pivot rod retained transversely within a channel in the handle, along with securing members and grip portions that stabilize and assist manual adjustment. A spring biasing member provides rotational resistance and recoil bias during use. In the primary embodiment, the spring comprises a torsion coil and extended arm retained under preload tension by a catch at the distal end of the handle. Alternative embodiments may utilize elastic springs or leverage gravitational force to achieve similar biasing effects. The design enables ergonomic control and dynamic blade positioning, with modular components that allow for varied resistance profiles and interchangeable biasing elements.
