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.

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.

The microcontroller is configured to send a second signal indicative of a change in force to the feedback indicator such that the feedback indicator generates a second indication including illumination in response to and representative of the change in force during the shaving session to assist the user with shaving.

Abstract: A constant rake planar cutting edge fluted drill bit and a method of manufacturing the same. The drill bit includes a planar cutting face formed at the tip end of the bit by a motion of a rotating machining wheel respective to a stationary blank in a first step. Once the cutting face is formed, the blank is rotated and translated in a direction parallel to an elongated axis, during which the rotating machining wheel creates a flute. Upon completion of the first flute, the bit is rotated accordingly and the processes are repeated to create each subsequent planar cutting face and respective flute. The process can also be completed in a slightly modified version of a reverse process, fabricating a flute prior to formation of the planar cutting face of the bit.
