When the trigger switch structure device for electric tools that prevents accidental touch is used, the contact assembly is driven to operate by pushing the switch to realize the use of the body. At this time, the card block is driven to be stuck in the card slot by the thrust of the spring, so that the switch controls the body to be used continuously without continuously pressing the switch, which is convenient for people to use; at the same time, the card block can be driven by the thrust of the spring to squeeze the lower surface of the switch, forcing the switch to be in the initial position, preventing people from using the device due to accidental touch, and improving the safety of people's use. The technical problem is recorded as follows: "Since electric tools generally have to be used under people's continuous control, the operation is cumbersome. At the same time, in the power-on standby state, the trigger is easily triggered by inadvertent touch, which is easy to cause danger."

[0004] It can be seen from the technical problems described in the above-mentioned patent disclosure that the switch on the existing power tool has the problem that it is easy to cause the power tool to operate unexpectedly due to inadvertent touch.

[0026] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Please refer to Figures 1 to 6 As shown, this embodiment provides an anti-mistaken touch switch for electric tools, comprising a switch body 2, the switch body 2 being mounted on a handle 1 of the electric tool body, and an anti-mistaken touch member for preventing the switch body 2 from being accidentally touched and closed is arranged inside the handle 1;

[0028] The anti-mis-touch component includes an elastic sheet 3, one end of which is connected to the inner wall of the handle 1, and the movable end of the elastic sheet 3 is fixedly connected with a clamping head 302. A clamping groove 201 is provided on the side of the switch body 2, and the clamping head 302 can be clamped into the clamping groove 201. In the embodiment, the clamping head 302 is semi-cylindrical, and the clamping groove 201 is a long arc shape. The lower end of the clamping head 302 is clamped into the clamping groove 201. It should be noted that the depth of the clamping groove 201 is less than the radius of the clamping head 302 to prevent the clamping head 302 from being completely stuck in the clamping groove 201.

[0029] By adopting the above technical solution, when not in use, the clamping head 302 is clamped in the clamping slot 201. When it is needed, the user presses the switch body 2 hard. When the pressure applied to the switch body 2 is greater than the elastic force of the elastic sheet 3, the clamping head 302 is pressed out of the clamping slot 201, so that the switch body 2 can be closed normally. After use, the switch body 2 is released. At this time, the switch body 2 moves outward again under the elastic force of the return spring in the switch body 2, so that the clamping head 302 is re-clamped into the clamping slot 201. When the switch body 2 is accidentally touched, the force applied to the switch body 2 is generally smaller than the elastic force of the elastic sheet 3, thereby effectively reducing the probability of the power tool being operated due to accidentally touching the switch body 2.

[0030] Specifically, the length of the card slot 201 is greater than the length of the card head 302 . With this configuration, the card head 302 can be stably inserted into the card slot 201 .

[0031] Specifically, in order to facilitate the installation of the elastic sheet 3, the inner wall of the handle 1 is integrally formed with a mounting groove 101, the inner wall of the mounting groove 101 and the inner wall of the handle 1 form a slot 105, the inner wall of the mounting groove 101 is provided with a threaded groove 102, and one side of the handle 1 is provided with a plug hole 103 connected to the slot 105, and the end of the elastic sheet 3 away from the clamping head 302 is provided with a mounting hole 301. After the end of the elastic sheet 3 away from the clamping head 302 is inserted into the slot 105, the mounting hole 301 is connected with the plug hole 103 and the threaded groove 102, and one end of the screw 4 passes through the plug hole 103 and the mounting hole 301 in turn and is fixedly installed in the threaded groove 102 by a thread.

[0032] Specifically, in this embodiment, the outer wall of the handle 1 is provided with a hidden groove 104 connected to the socket 103, and the nut of the screw 4 is arranged in the hidden groove 104. Through this arrangement, the screw 4 can be effectively prevented from protruding from the surface of the handle 1, thereby ensuring the comfort when holding the handle 1.

[0033] Specifically, in order to ensure the service life of the elastic sheet 3, the elastic sheet 3 is an aluminum alloy spring sheet, so that it has good wear resistance and oxidation resistance.

[0034] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
