[0025] The practical working principle of the present invention is as follows: during use, the staff selects a suitable output module according to the on-site conditions. When the welding function is needed, the staff first connects the welding housing 31 to the clamping mechanism 6 through the rounded connecting block 4, so that the clamping block 62 in the clamping mechanism 6 slides in the second guide groove 41. At the same time, the clamping block 62 lifts the position of the sliding protection cover 7 upward, so that the sliding protection cover 7 no longer covers the input hole on the welding housing 31. At the same time, the second limiting strip 42 slides in the limiting slide groove 61 until the second boss contacts the fixing block 63, and then the limiting pin is inserted into the second through hole and the threaded hole 64 on the second boss to complete the assembly of the welding module 3 and the welding gun handle 1. The staff can operate the welding gun handle 1 to perform welding through the welding module 3. When the rust removal function is needed, the limiting pin is first removed from the second through hole and the threaded hole 64, and then the welding module 3 is lifted to the top of the welding gun handle 1 so that the second limiting pin is inserted into the second through hole and the threaded hole 64. The strip 42 and the block 62 slide out of the limiting slide groove 61 and the second guide groove 41 respectively, so that the welding module 3 can be separated from the welding gun handle 1. During the separation, the block 62 no longer lifts the sliding protection cover 7, so that the sliding protection cover 7 blocks the inlet on the welding shell 31 under the action of the spring 71 to prevent dust from entering. Then, the rust removal module 2 is connected to the clamping mechanism 6 through the rectangular connecting block 5, so that the block 62 in the clamping mechanism 6 slides in the first guide groove 51, and at the same time, the block 62 lifts the position of the sliding protection cover 7 upward, so that the sliding protection cover 7 no longer covers the inlet on the rust removal shell 21. At the same time, the first limiting strip 52 slides in the limiting slide groove 61 until the first boss contacts the fixing block 63, and then the limiting pin is inserted into the first through hole and the threaded hole 64 on the first boss, so that the assembly of the welding module 3 and the welding gun handle 1 can be completed, and the staff can operate the welding gun handle 1 to perform welding work through the welding module 3.
