Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4The present invention provides an improved push-pull wire welding gun, comprising a gun body 100, a gun barrel 101 at the end of the gun body 100, an installation tube 103 on the outer surface of the gun barrel 101, side arms 104 on both outer surfaces of the installation tube 103, a movable arm 105 rotatably mounted at the end of the side arm 104, an angle adjustment mechanism 200 between the side arm 104 and the movable arm 105, and a guide wheel 106 mounted at the bottom of the movable arm 105 via a length adjustment mechanism 300.

[0027] In use, the gun body 100 can be held by hand, and both guide wheels 106 can be simultaneously brought into contact with the workpiece. During welding, the gun body 100 can be moved horizontally via the guide wheels 106 to weld the joint. Since the guide wheels 106 provide support for the barrel 101, the operator's hand stress is reduced, minimizing fatigue. Furthermore, the guide wheels 106 can position the distance between the end of the barrel 101 and the workpiece, improving welding quality. The angle adjustment mechanism 200 allows for adjustment of the guide wheel 106's angle, and the length adjustment mechanism 300 allows for adjustment of the guide wheel's length. The distance between the guide wheel 106 and the end of the barrel 101 can be adjusted, enabling the welding torch to perform welding operations under different conditions. For example, when the two workpieces are in a parallel position, the two guide wheels 106 are adjusted to be parallel to each other, so that the two guide wheels 106 can roll on the two workpieces respectively for welding during the welding process. When the two workpieces are in a perpendicular angle, the angle and length of the two guide wheels 106 are adjusted so that when the barrel 101 is aligned with the weld at a 45-degree angle, the two guide wheels 106 can still roll vertically on the two workpieces for welding, which is highly flexible.

[0028] Specifically, the angle adjustment mechanism 200 includes multiple first screw holes 201 formed on the side surface of the movable arm 105, and the multiple first screw holes 201 are arranged coaxially. A first screw 202 is installed on the outer surface of the side arm 104, and the first screw 202 matches the first screw hole 201. By unscrewing the first screw 202 out of the first screw hole 201, the movable arm 105 is released from fixation, so it can be rotated and the angle adjusted. After the angle is adjusted, the first screw 202 is screwed back into the first screw hole 201 to fix the movable arm 105 again, thereby achieving the purpose of adjusting the angle.

[0029] Specifically, the length adjustment mechanism 300 includes a connecting groove 301 inside the movable arm 105, a mounting block 302 inserted inside the connecting groove 301, and a guide wheel 106 rotatably mounted on the end of the mounting block 302. The side surface of the mounting block 302 has multiple second screw holes 303 along its length direction. The outer surface of the movable arm 105 is fitted with a second screw 304, which matches the second screw hole 303. When adjusting the position of the guide wheel 106, the second screw 304 can be unscrewed from the second screw hole 303 first, and then the mounting block 302 can be slid up and down to adjust the position of the guide wheel 106. After the position is adjusted, the second screw 304 can be screwed back into the second screw hole 303 for fixation, thereby completing the purpose of position adjustment.

[0030] Specifically, a sleeve 102 is provided on the outer surface of the barrel 101, and a mounting tube 103 is sleeved and rotatably mounted on the outer surface of the sleeve 102. Two third screw holes 400 are opened on the outer surface of the sleeve 102, and a third screw 401 is installed on the outer surface of the mounting tube 103. The third screw 401 matches the third screw hole 400. By screwing the third screw 401 into different third screw holes 400 respectively, the direction of the two guide wheels 106 can be adjusted.

[0031] Specifically, a connecting arm 500 is installed on the outer surface of the sleeve 102. The end of the connecting arm 500 is connected to the gun body 100 by bolts. The connecting arm 500 connects the sleeve 102 to the gun body 100 and provides support, so that the sleeve 102 does not come into contact with the gun barrel 101 and does not exert force on the gun barrel 101, thus avoiding deformation of the gun barrel 101. In addition, the bolt connection allows the sleeve 102 to be removed from the gun barrel 101 to meet different usage requirements.

[0032] Specifically, a reinforcing arm 600 is installed on the outer surface of the connecting arm 500. The end of the reinforcing arm 600 is connected to the gun body 100 by bolts. By setting the reinforcing arm 600, the structural strength of the connecting arm 500 can be strengthened and its structural stability can be improved.

[0033] Specifically, the included angle between the two third screw holes 400 is 90 degrees. When the third screw 401 is screwed into the two third screw holes 400 respectively, the forward direction of the gun body 100 can be changed, and the gun body 100 can be handheld for horizontal and vertical welding.

[0034] Specifically, the outer surface of the handle of the gun body 100 is provided with a rubber pad, and the outer surface of the rubber pad is provided with anti-slip texture. The rubber pad and anti-slip texture can increase the friction with the hand and improve hand comfort.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
