A first spring support block 124 is provided on the side of one of the several first limiting holes 123 near the first spring seat groove 121, which is used to limit the end of the spring 8 away from the spring seat 3, ensuring the stability of the spring 8 installation.

[0031] Based on the above scheme, a second spring seat groove 221 is provided above the front end of the second hand grip 22, which cooperates with the first spring seat groove 121 to form the installation space of the spring seat 3. A second shaft hole 225 is provided in the second spring seat groove 221, that is, by inserting the fixing shaft 32 on the left side of the spring seat 3 into the first shaft hole 125 and the fixing shaft 32 on the right side of the spring seat 3 into the second shaft hole 225, the spring seat 3 can be rotated and installed. A second mounting rib groove 222 is provided in the second hand grip 22. The first mounting rib groove 122 and the second mounting rib groove 222 cooperate to form the mounting cavity of the welding torch wrench 6, which facilitates the installation of the welding torch wrench 6; at the same time, it can also improve the structural strength of the second hand grip 22 of the right half grip shell 2. The upper edge of the second mounting groove 222 is provided with several second limiting holes 223 for installing the other end of the buckle 5. By inserting one end of the buckle 5 into the first limiting hole 123 and the other end of the buckle 5 into the second limiting hole 223, the upper ends of the first hand grip 12 and the second hand grip 22 are connected. This displacement is within the middle of the entire grip modification structure, which not only supports the internal space of the grip modification structure but also strengthens its structural strength. A second spring support block 224 is provided on the side of one of the second limiting holes 223 near the second spring seat groove 221. This block is used to limit the spring 8 at the end furthest from the spring seat 3, ensuring the stability of the spring 8 installation.

[0032] Based on the above scheme, the first mounting groove 122 is provided with a plurality of insertion holes 126 for the installation of the elastic support 7. The elastic support 7 is used to position and fix the welding torch wrench 6, preventing the welding torch wrench 6 from falling off. The lower end of the first spring seat groove 121 is provided with a first limiting groove 127, and the lower end of the second spring seat groove 221 is provided with a second limiting groove 226. The lower end of the spring seat 3 is limited by the first limiting groove 127 and the second limiting groove 226, preventing the lower end of the spring seat 3 from separating from the left half grip shell 1 and the right half grip shell 2 under the action of the compression spring 8.

[0033] Based on the above scheme, an elastic support 7 is inserted into each socket 126, and multiple elastic support 7s are used to achieve multi-part pressure positioning of the welding torch wrench 6. The elastic support 7 includes a slotted column 71, and a hemisphere 72 is installed at one end of the slotted column 71. The end of the hemisphere 72 near the slotted column 71 is connected to a support spring installed inside the slotted column 71. The slot at the bottom of the slotted column 71 facilitates the insertion of the slotted column 71 into the socket 126. The support spring provides elastic support for the hemisphere 72, ensuring that the hemisphere 72 can move left and right relative to the slotted column 71, making it easy for the welding torch wrench 6 to be inserted into or pulled out of the modified grip structure.

[0034] In this application, the spring seat 3 has a 7-shaped structure, with a wave-shaped pressing surface 31 on its front side. This increases the friction of the pressing surface 31, preventing slippage due to sweaty hands, and also accommodates the grip of the operator's hand. A fixed shaft 32 is provided on both the left and right sides of the spring seat 3, for insertion into the first shaft hole 125 and the second shaft hole 225, enabling rotatable connection between the spring seat 3 and the left half-grip housing 1 and the right half-grip housing 2. A spring connecting shaft 33 is provided on the rear side of the spring seat 3 for connecting the spring seat 3 to the compression spring 8, thereby fixing the end of the compression spring 8.

[0035] In the solution of this application, the buckle 5 includes a sub-buckle 51 and a female buckle 52. The sub-buckle 51 is inserted into one of the first limiting hole 123 or the second limiting hole 223, and the female buckle 52 is inserted into the other of the first limiting hole 123 or the second limiting hole 223. When the sub-buckle 51 and the female buckle 52 are engaged, the middle parts of the left half grip shell 1 and the right half grip shell 2 can be connected together. The end of the sub-clamp 51 near the end of the female clamp 52 is provided with a clamp connecting post 511, and the end of the clamp connecting post 511 away from the female clamp 52 is provided with an annular groove 512. The female clamp 52 is provided with a clamp connecting hole 521, which is a stepped structure. When the sub-clamp 51 and the female clamp 52 are connected, the clamp connecting post 511 is inserted into the large diameter part of the large clamp connecting hole 521, and the annular groove 512 is locked by the small diameter part of the clamp connecting hole 521. This can prevent the clamp connecting post 511 from separating from the clamp connecting hole 521 and ensure the firmness of the connection between the sub-clamp 51 and the female clamp 52.

[0036] In this application, one end of the welding torch wrench 6 has several screw diameter holes 61 of different diameters along its length, which are used for rotating hexagonal bolts of different sizes and can also be used as hanging holes for the modified grip structure. The other end of the welding torch wrench 6 has several positioning holes 62 of different diameters along its length, which are used to cooperate with the elastic support 7 to achieve positioning and fixing of the welding torch wrench 6.

[0037] In another embodiment of this application, a plurality of first mounting through holes 13 are pre-set on the left half grip shell 1, and a plurality of second mounting through holes 23 are pre-set on the right half grip shell 2. One of the first mounting through holes 13 and the second mounting through holes 23 has an internal thread structure.
