Further, referring to fig. 1, the triggering member 131 includes a button 1311 and a striker 1312, the button 1311 is fixedly connected to the striker 1312, the second mounting bracket 132 has a guide hole opposite to the ignition chamber 124, the striker 1312 passes through the guide hole and is disposed toward the ignition chamber 124, and one end of the elastic member 133 is connected to the second mounting bracket 132 and the other end is connected to the button 1311.

Specifically, in this embodiment, the fixed connection manner of the button 1311 and the striker 1312 may be any one of various non-detachable fixed connection manners, such as integral molding, welding, and adhesion, which are commonly used by those skilled in the art, and those skilled in the art may design according to actual situations and specific requirements, which is not specifically limited in this embodiment.

More specifically, in this embodiment, the shape of the button 1311 may be rectangular, circular, square, etc., and those skilled in the art can design the button according to actual situations and specific requirements, which is not specifically limited in this embodiment.

More specifically, in the present embodiment, in order to prevent the cutting device 10 from being triggered by mistake, a mistake-touch prevention cover may be disposed on the button 1311, and a clear indication of mistake-touch prevention may be made on the mistake-touch prevention cover.

In this embodiment, the guiding hole of the second mounting bracket 132 has a certain guiding function for the primer of the striker 1312 impacting the inner bottom fire cap 124b of the ignition chamber 124, so that the striker 1312 can accurately impact the primer of the inner bottom fire cap 124b of the ignition chamber 124. The evacuee can push the button 1311 to drive the striker 1312 to strike the primer in the primer cap 124b in the ignition chamber 124, which is convenient to operate.

Further, referring to fig. 1, the elastic member 133 is a spring, the spring is sleeved on the firing pin 1312, and an edge portion is provided at one end of the firing pin 1312 close to the ignition chamber 124.

In this embodiment, the blade portion at the end of the striker 1312 near the ignition chamber 124 can deform the primer cap 124b greatly, so as to trigger the primer in the primer cap 124b to burn.

While the utility model has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a more detailed description of the utility model, taken in conjunction with the specific embodiments thereof, and that no limitation of the utility model is intended thereby. Various changes in form and detail, including simple deductions or substitutions, may be made by those skilled in the art without departing from the spirit and scope of the utility model.
