[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings. Example 1

[0024] A preferred embodiment of a argon arc welding machine with an anti-interference function provided by the present invention is as follows: Figures 1 to 7 As shown: A argon arc welding machine with anti-interference function, comprising a fixing plate 1, A pulley 2 is fixedly mounted on the bottom of the fixed plate 1; A moving wheel 3 is fixedly mounted on the bottom of the fixed plate 1; and a protection assembly 4 disposed at the top of the fixing plate 1; The protection assembly 4 includes a protection mechanism 41 installed at the top position of the fixed plate 1; A protection mechanism 42 is installed at the bottom of the fixing plate 1, and the protection mechanism 42 is located at the left side of the protection mechanism 41; An auxiliary mechanism 43 is installed at the top of the fixing plate 1 , and one end of the auxiliary mechanism 43 is connected to the protection mechanism 41 .

[0025] The protection mechanism 41 includes a protection lower shell 4110, which is fixedly mounted on the top of the fixed plate 1, and the inner wall of the protection lower shell 4110 is provided with a slot on which a plug-in block 413 is slidably mounted, and a protection block 412 is fixedly mounted on the top of the plug-in block 413, and the bottom of the protection block 412 is in contact with the top of the protection lower shell 4110, and a clamping block 411 is fixedly mounted on the inner wall of the protection block 412, and the side wall of the clamping block 411 is slidably connected to the inner wall of the protection lower shell 4110, and an electric The motor 414 is movable through the rotating shaft at the output end through the front side of the protective lower shell 4110 and extends to the inner wall of the protective lower shell 4110, and is transmission-mounted with a bidirectional threaded rod 415, a displacement block 417 is installed on the side wall of the bidirectional threaded rod 415, a positioning block 418 is fixedly installed on the side wall of the displacement block 417, one end of the bidirectional threaded rod 415 is transmission-mounted with a connecting belt 419, the other end of the connecting belt 419 is transmission-mounted with a bidirectional threaded rod 416, and a displacement block 417 is installed on the side wall of the bidirectional threaded rod 416.

[0026] In this embodiment, the side wall of the bidirectional threaded rod 415 is threadedly connected to the inner wall of the displacement block 417, and the side wall of the displacement block 417 is slidingly connected to the inner wall of the protective lower shell 4110. There are four displacement blocks 417, and the shapes and sizes of the four displacement blocks 417 are equal. Two displacement blocks 417 are a group and are symmetrically arranged relative to the center surface in the left and right directions of the protective lower shell 4110. When the bidirectional threaded rod 415 rotates, it can drive the position of the displacement block 417 to move.

[0027] Furthermore, the side wall diameter of the positioning block 418 is the same as the inner wall diameter of the circular groove opened on the side wall of the clamping block 411.

Then the operator can directly turn on the motor 414, and the motor 414 drives the position of the two-way threaded rod 1 415 to rotate through the rotating shaft at the output end. The two-way threaded rod 1 415 can drive the position of the two-way threaded rod 2 416 to rotate under the action of the connecting belt 419. The threaded rod 416 and the bidirectional threaded rod 415 are both threadedly connected to the inner wall of the displacement block 417. Therefore, when the bidirectional threaded rod 415 and the bidirectional threaded rod 416 are rotated, the displacement block 417 can be driven to be closer to each other, and the displacement block 417 will drive the position of the positioning block 418 to move, and one end of the positioning block 418 will enter the inner wall of the clamping block 411, thereby limiting the position of the clamping block 411, improving the stability of the clamping block 411, and facilitating the operator to install the protective lower shell 4110 and the protective block 412, which can effectively prevent the argon arc welding machine body 7 from being interfered with by external electromagnetics when it is working.
