[0030] Embodiment 1:

[0031] Please refer to Figures 1-5, a new type of welding torch handle, including a first half-shell handle body 1 and a second half-shell handle body 2. A gun head groove 18 is provided inside the first half-shell handle body 1, and a wire groove 19 is provided inside the second half-shell handle body 2, so as to facilitate the installation of the gun head and the wire between the first half-shell handle body 1 and the second half-shell handle body 2. A trigger structure 5 is provided on the inner side of the upper end of the first half-shell handle body 1. When it is necessary to install and fix between the first half-shell handle body 1 and the second half-shell handle body 2, in order to guide the alignment and fitting between the first half-shell handle body 1 and the second half-shell handle body 2, guide plates 6 are symmetrically fixed at the top end of the second half-shell handle body 2. Both of the two guide plates 6 are located inside the first half-shell handle body 1 and are slidably connected to the first half-shell handle body 1. Socket seats 10 are symmetrically fixed at the lower end of the second half-shell handle body 2. Positioning holes 11 are symmetrically provided inside the lower end of the first half-shell handle body 1. The socket seats 10 are located inside the positioning holes 11 and are slidably connected to the positioning holes 11;

[0032] After the first half-shell handle body 1 and the second half-shell handle body 2 are aligned and fitted, and the guide plates 6 are located inside the first half-shell handle body 1 and the socket seats 10 are located inside the positioning holes 11, in order to fix between the first half-shell handle body 1 and the second half-shell handle body 2, pull rods 7 are symmetrically and slidably connected inside the first half-shell handle body 1 and outside the two guide plates 6. One end of each pull rod 7 is slidably connected to the guide plate 6. A spring 8 is fixed between the outer side of the other end of the pull rod 7 and the first half-shell handle body 1. An insert block 12 is provided inside each positioning hole 11. The insert block 12 is fixed to the first half-shell handle body 1. An anti-slip layer is provided on the outer side of the insert block 12. The insert block 12 is located inside the socket seat 10 and is tightly fitted with the socket seat 10 by using the anti-slip layer, so as to improve the installation and fixing effect between the first half-shell handle body 1 and the second half-shell handle body 2;

[0033] When a person holds this handle, a palm anti-slip rubber sleeve 3 is fixed at the center of the outer side of the first half-shell handle body 1, and a finger anti-slip rubber sleeve 4 is fixed at the center of the outer side of the second half-shell handle body 2, which improves the holding comfort and has an anti-slip effect. At the same time, a heat insulation washer 9 is sleeved outside the first half-shell handle body 1 and the second half-shell handle body 2 and above the palm anti-slip rubber sleeve 3 and the finger anti-slip rubber sleeve 4. The heat insulation washer 9 is fixed to the first half-shell handle body 1, which is convenient for blocking the heat radiated in the gun head direction to a certain extent;

[0034] Embodiment 2:

[0035] Further optimize the new type of welding torch handle provided in Embodiment 1. Specifically, as Figure 2 and Figure 5As shown in the figure, a second wire protection half-sleeve 14 is fixed to the bottom end of the first half-shell handle body 1, and a first wire protection half-sleeve 13 is fixed to the bottom end of the second half-shell handle body 2. A hollow threaded tail handle 17 is threadedly connected to the outer side between the first wire protection half-sleeve 13 and the second wire protection half-sleeve 14. After the hollow threaded tail handle 17 is threadedly connected to the outer side between the first wire protection half-sleeve 13 and the second wire protection half-sleeve 14, the first half-shell handle body 1 and the second half-shell handle body 2 are further fixed. Moreover, the first wire protection half-sleeve 13, the second wire protection half-sleeve 14, the gun head groove 18, and the wire groove 19 are internally communicated, facilitating the connection of the wire.

[0036] After the hollow threaded tail handle 17 is sleeved on the outer sides of the first wire protection half-sleeve 13 and the second wire protection half-sleeve 14 and threadedly connected to them, in order to further increase the damping of the fit between the hollow threaded tail handle 17 and the first wire protection half-sleeve 13 and the second wire protection half-sleeve 14, thereby improving the fixing effect, a first half rubber pad 15 is fixed to the upper end of the outer side of the first wire protection half-sleeve 13, and a second half rubber pad 16 is fixed to the upper end of the outer side of the second wire protection half-sleeve 14. The bottom ends of the first half rubber pad 15 and the second half rubber pad 16 are both in contact with the hollow threaded tail handle 17.

[0037] The use process of the new soldering gun handle provided by the present utility model is as follows: When the first half-shell handle body 1 and the second half-shell handle body 2 need to be assembled, the guide plate 6 is slid into the inner side of the first half-shell handle body 1, and the socket 10 is slid into the inner side of the positioning hole 11, so that the first half-shell handle body 1 and the second half-shell handle body 2 are quickly positioned and aligned and fitted. And before the guide plate 6 is slid in, the pull rod 7 is pulled, and after the guide plate 6 is completely slid in, the pull rod 7 is released. The elastic characteristic of the spring 8 drives the pull rod 7 to reset and slide into the inner side of the guide plate 6. Cooperating with the fit between the insert block 12 and the inner side of the socket 10, the quick installation and fixation between the first half-shell handle body 1 and the second half-shell handle body 2 are realized, and no additional tools are required. At this time, after the hollow threaded tail handle 17 is threadedly connected to the outer side between the first wire protection half-sleeve 13 and the second wire protection half-sleeve 14, the hollow threaded tail handle 17 is tightened so that its top end is in close contact with the first half rubber pad 15 and the second half rubber pad 16, further improving the installation and fixation effect between the first half-shell handle body 1 and the second half-shell handle body 2, and the overall disassembly and assembly operation is convenient.
