Abstract: The invention discloses a folding knife, comprising: a blade, whose upper part is configured with a lockup switch mounting hole; a handle, whose lower part is configured with a stopping slot; a lockup switch provided in the lockup switch mounting hole and having a lockup part located on the first side of the blade, the lockup part has a lockup position at which it is clapped in the stopping slot when the blade and the handle are buckled up and an unlock position at which it is released from the stopping slot when the blade is separated from the handle. The folding knife of the invention enables safe locking after the blade is folded in the handle by making use of the lockup switch having a lockup part, the structure of the folding knife is simple and easy to implement, and safety performance of the folding knife is improved.

Abstract: The invention discloses a lamp with an assembling and disassembling function, which includes a lamp tube, wherein a fixing element for mounting with an equipment guide rail is arranged on the lamp tube, and the fixing element includes a mounting sliding chute, which is adapted to the equipment guide rail, so that the mounting sliding chute can slide into the equipment guide rail; a locking element, which is arranged in the mounting sliding chute and is pressed against and matched with a groove of the equipment guide rail to fix the lamp tube on the equipment guide rail; and an operating element, an outer contour of the operating element being exposed from an outer contour of the lamp tube, an interior of the operating element being connected with the locking element, the rotating element being rotated to drive the locking element to lock and unlock equipment.

Abstract: The disclosure provides a dimmable torch, in order to overcome the insufficiency of the dimming control function of the torch in the prior art. The torch comprises a lamp holder (1), a tube body (3) and a tail cap (5), wherein a battery (10) is arranged in the tube body (3); a control circuit (9) is arranged in the tail cap (5) of the torch; the second end (V?) of the control circuit is connected with the cathode of the battery (10); a microcomputer control system (8) on the control circuit (9) can control the on/off of a loop of the cathode of the second end of the driving circuit (11) and the cathode of the battery (10) to implement dimming. Due to the disclosure, the grouped multi-gear dimming mode of the torch can be controlled conveniently.
