[0002] With the development of power tools, the power of DC power tools is increasing day by day, which also increases the danger of the tools. The electronic module of the switch of common power tools is enclosed inside the housing.

[0003] Existing power tool switches are prone to slippage and misoperation during use, affecting work efficiency and safety. Traditional switch designs lack effective self-locking and anti-slip mechanisms, leading to unstable operation. Users need to exert extra force to hold the switch in place, increasing the difficulty and fatigue of use. Therefore, developing a switch with self-locking and anti-slip functions is particularly important. Utility Model Content

[0004] The purpose of this invention is to provide a self-locking anti-slip switch for power tools to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-locking anti-slip switch for power tools, comprising a housing: a button cap is rotatably mounted on the top of the housing; sliding grooves are provided on both sides of the top of the housing; a locking groove is provided in the middle of both sides of the button cap; the housing is slidably provided with a locking anti-slip structure through the sliding grooves; a locking member is provided at both ends of the housing; a pressing member is provided in the middle of the bottom of the button cap; an elastic member is provided at one end of the housing; a moving contact, a normally closed contact, and a normally open contact are sequentially arranged on the bottom of the housing from the side closest to the elastic member; a connecting member is provided between the moving contact, the normally closed contact, and the normally open contact on the bottom of the housing.

[0006] The locking anti-slip structure includes a push rod, with connecting blocks on both sides of the push rod, a slider at the bottom of the connecting blocks, and a locking lever at the middle position of the slider near the button cap.

[0007] By adopting the above technical solution, the user can move the locking anti-slip structure on the housing, so that the locking anti-slip structure can fix the tilt direction of the button cap, avoiding the need for the user to exert extra force to fix the tool switch when using the electric switch, and at the same time preventing the switch on the power tool from being accidentally activated.

[0008] Preferably, a rotating opening is provided at the middle position of the top of both sides of the housing, and a rotating component is provided at the middle position of both sides of the button cap. The housing is rotatably connected to the button cap through the rotating opening and the rotating component.

[0010] Preferably, the size of the groove is adapted to the size of the slider, and the groove and the slider are slidably connected.

[0011] By adopting the above technical solution, the locking anti-slip structure can slide stably on the housing through the slider and the groove, so that the locking anti-slip structure can fix the tilt direction of the button cap and prevent accidental activation of the switch during use.

[0012] Preferably, the size of the slot is adapted to the size of the lever, and the button cap is slidably connected between the slot and the lever.

[0013] By adopting the above technical solution, the locking rod on the anti-slip structure and the slot on the button cap are matched.

When the locking rod is in the middle position of the slot, the user can change the tilt direction of the button cap.

[0014] Preferably, the extrusion member consists of a sleeve, a spring, and an extrusion head, with the spring and extrusion head both located inside the sleeve.

[0015] By adopting the above technical solution, when the user changes the tilt direction of the button cap, the direction of the extrusion component will change, thereby extruding the rocker conductive component so that the rocker conductive component can contact the normally open contact piece. The extrusion component, through the cooperation between the spring and the extrusion head, can make the extrusion head on the extrusion component tightly fit the rocker conductive component.

[0016] Preferably, a support member is provided at the middle position inside the housing, and the top and bottom of the elastic member are connected to the button cap and the support member, respectively.

[0017] By adopting the above technical solution, the elastic element is stably and securely installed inside the housing through the support member.

[0020] Preferably, the top of the movable contact piece is provided with a rocker conductive element, the extrusion member abuts against the rocker conductive element, a rectangular groove is opened at the top of one end of the normally closed contact piece, the normally closed contact piece is slidably connected to the rocker conductive element through the rectangular groove, and a contact point is provided at the top of the normally open contact piece.

[0021] By adopting the above technical solution, when the button cap is tilted towards the end of the elastic element, it can drive the pressing element to push the rocker conductive element on the moving contact piece, so that the rocker conductive element contacts the contact on the normally open contact piece, thereby connecting the circuit inside the switch.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the power tool uses a self-locking anti-slip switch with a locking anti-slip structure. By pushing the locking anti-slip structure, the user can change the position of the locking anti-slip structure, thereby fixing the tilt direction of the button cap. This eliminates the need for the user to exert extra force to fix the tool switch when using the power tool, reducing the difficulty and fatigue of the user. At the same time, it can prevent accidental activation of the power tool switch during use. Attached Figure Description
