Abstract: A handle mechanism with multiple stop locations and a lawn mower including the handle mechanism includes a handle and a location shifting element with multiple stop locations, the handle being provided with a locking mechanism that is automatically clamped with one of the multiple of stop locations of the location shifting element for fixing or adjusting the handle. A lawn mower, including the handle mechanism, includes a lawn mower body, the handle rotatably connected with the lawn mower body by the handle rotating shaft. The locking mechanism and the location shifting element are equipped with stop locations can be automatically locked, therefore, the operator can adjust the stop locations of the lawn mower conveniently. The locking at the stop locations is accurate and reliable, which largely improves portability, flexibility, and reliability of use.

Abstract: An electric circular saw includes a housing, a switch trigger arranged on the housing, a switch controlling rod for limiting the travel range of the switch trigger, a base plate, a depth support arranged on the base plate and a connecting rod for limiting the travel range of the depth support. The electric circular saw further includes an movable control member having a driving portion for driving the first connecting rod and a limiting portion for limiting the switch controlling rod, and the moving distance from the driving portion to a contact surface between the driving portion and the first connecting rod is larger than or equal to the moving distance from the limiting portion to a contact surface between the limiting portion and the switch controlling rod.

Abstract: The multi-tool for fasteners includes a housing, a power device, a transmission device coupled to the power device, an output device coupled to the transmission device, and a switching device that can be switched between at least two operating modes. In a first operating mode, the output device moves in a reciprocating manner without rotation along an axial direction. In a second operating mode, the output device rotates with an intermittently increasing torque about a circumferential direction. The switching device may include a limiting member and the limiting member can be moved between a first position and a second position. Further, in the first position the output device is in the first operating mode, and in the second position the output device is in the second operating mode.

Abstract: The invention provides an electric weeder, including a housing, a driving device, a working head, and a removable handle. The driving device is disposed in a housing, and including an axis line. The working head is connected to the axis line and driven by the driving device; the removable handle moves relative to the working head and the housing, and wherein on end of the removing handle is movably connected to the housing, the other end includes a removing plate, and the removing plate includes a through portion being passed through by the working head. The electric weeder of the present invention can exactly weed the lawn with little damage, the overall structure of the machine is more simple to effectively reduce the overall length of the machine; the removable handle can remove the weeds automatically to lower the work intensity and increase the weeding efficiency.

Abstract: A palm electric tool includes a housing adapted for palm gripping, a base connected to the housing for contacting with a workpiece and supporting the palm electric tool, a motor with an output shaft arranged within the housing. The output shaft is substantially parallel to the base. A transmission mechanism is connected to the output shaft of the motor which includes a slide bar. The slide bar is capable of being moved in a direction perpendicular to the output of the motor, a blade is connected to the slide bar which is positioned substantially perpendicular to the output of the motor and the base. A battery pack for powering the motor is inserted into the housing. An inserting direction of the battery pack is substantially parallel to the output shaft of the motor. The battery pack is positioned between the motor and the base and partially overlapped with the motor in a direction perpendicular to the base.

Abstract: A power starting circuit used in a DC power supply circuit has a double-pole, double-throw switch electrically connected to a positive pole of a DC power supply and controls a conducting state of the circuit. A first capacitor provides a voltage signal for a first switch circuit and controls the conducting state of the first switch circuit in a continuous charging and discharging process. The first switch circuit controls the conducting state of the DC power supply circuit. A maintaining signal input end provides a maintaining signal for the first capacitor. The power starting circuit can achieve an over discharge protection function for the control circuit. Moreover, when the switch is turned on, it can automatically switch the circuit off so as to save power if the electrical product does not need to continue to work.
