[0024] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a kind of clamping tool for initiating explosive device, including cartridge 3, bracket 4 being arranged below cartridge 3, four lugs 401 being fixed in annular array outside bracket 4, four positioning blocks 402 being fixed staggeredly outside bracket 4 and being located between four lugs 401 and support frame 403 being fixed staggeredly outside bracket 4 and being located between lug 401 and the clearance between positioning block 402, the lower end middle part of bracket 4 is provided with tool base 1, the upper end outside of tool base 1 is fixedly connected with four orientation support blocks 101 towards positioning block 402, and the left and right ends of tool base 1 are both fixedly connected with clamping mechanism for lug 401 to be labor-saving folded inwards and combined on cartridge 3.

[0026] Specifically, as shown in Figs. 1-3 Clamping mechanism includes two rotating frames 104 fixed symmetrically on the left and right ends of tool base 1, handle 2 rotatably installed between two rotating frames 104 through rotating shaft 201 and bending protrusion 202 fixed on one end of handle 2 towards lug 401, when bending protrusion 202 rotates upwards and contacts lug 401, lug 401 distributed vertically can be bent inwards to horizontal state, and then lever action of handle 2 can fix lug 401 on cartridge 3 labor-savingly.

[0027] Among them, the width of handle 2 and bending protrusion 202 is same with the spacing between two rotating frames 104, which can prevent handle 2 from shaking between tool base 1 and two rotating frames 104, and improve the stability of rotating adjustment of handle 2, the width of handle 2 and bending protrusion 202 is greater than the width of lug 401, which can cover lug 401 as a whole, to ensure that lug 401 can be completely bent and covered on cartridge 3.

[0028] Specifically, as shown in Fig. 1 And Fig. 3 The upper end of orientation support block 101 is provided with limiting clamping groove 102 for accommodating positioning block 402, the setting of limiting clamping groove 102 can hide positioning block 402 in orientation support block 101, which can further prevent bracket 4 from moving axially between tool base 1 and orientation support block 101, and improve the stability of bracket 4 placed on tool base 1.

[0029] Specifically, as shown in Fig. 1 AndFig. 3 As shown in the drawings, the tool base 1 and the handle 2 are integrally made of stainless steel material, and the outer surfaces of the tool base 1 and the handle 2 are formed with copper plating layers by electroplating. Considering that the clamping tool as a whole needs certain structural strength and needs to have corrosion resistance and anti-static requirements, the clamping tool as a whole is made of stainless steel and is treated by copper plating process.

[0030] Specifically, as shown in the drawings, Fig. 1 and Fig. 3 The tool base 1 is fixedly connected with an anti-skid boss 103 in the shape of a circular truncated cone structure at the lower end, which facilitates the operator to hold the tool base 1 with the hands, and after the hands are held between the tool base 1 and the anti-skid boss 103, the tool base 1 as a whole can be stably fixed on the table top.

[0031] Working principle: in use, first, the positioning block 402 on the support 4 is aligned and buckled downward into the positioning support block 101 of the tool base 1, and when the positioning block 402 is completely slid into the limiting clamping groove 102 of the positioning support block 101, the powder box 3 can be placed on the tool base 1 and the upper end of the support 4, secondly, the operator uses one hand to press and fix the powder box 3 and the support 4 on the tool base 1, and the other hand holds and rotates the handle 2 upward, in this process, the bent boss 202 on the handle 2 can contact and press the lug 401, and the lug 401 is continuously bent and buckled and fixed on the powder box 3, finally, when the two lugs 401 are bent and buckled, the support 4 and the powder box 3 as a whole can be lifted upward from the tool base 1, and then rotated by 90° and positioned downward on the tool base 1, so that the handle 2 can continue to bend and buckle the other two lugs 401 on the powder box 3, and the convenient assembly operation of the primer device is completed.

[0032] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
