[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a shake-resistant pendulum handheld welding gun, including a gun body 1, which serves as the main frame of the pendulum handheld welding gun. It integrates a pendulum drive mechanism and an optical focusing system, employing a front-focusing design. Guide rails 2 are fixedly connected to both the left and right sides of the gun body 1, providing a guide track for the movement of a slider 3. The slider 3 can be fixed on the guide rails 2. Multiple slots 10 are provided on the outer side of the guide rails 2, which cooperate with the connectors 91 to fix the slider 3. A slider 3 is installed on the outer side of the guide rails 2 via a limiting component 9, used to install support legs 4. Support legs 4 are rotatably connected to the outer side of the slider 3, used to support fixing components 5. Fixing components 5 are provided on the outer side of the support legs 4, allowing for length adjustment to adapt to different welding trajectories. A support plate 6 is rotatably connected to the lower part of the fixing component 5, used to install multiple sets of rollers 7. Multiple sets of rollers 7 are rotatably connected through the inner wall of the support plate 6. Adjacent sets of rollers 7 are fixed by a rotating shaft, which rotates through the inner wall of the support plate 6. An adjustment component 8 is provided on the upper part of the support legs 4.

[0031] Reference Figures 2-4 The adjustment component 8 includes an adjustment groove 82. Multiple sets of adjustment grooves 82 are evenly distributed on the outer side of the slider 3 with the rotation connection of the support leg 4 as the center point. The adjustment grooves 82 are threadedly connected to the inner wall of the adjustment grooves 82 by bolts b81, thereby fixing the angle of the support leg 4. The adjustment grooves 82 are opened on the inner wall of the slider 3, and bolts b81 are threadedly connected to the inner wall of the adjustment grooves 82. The bolts b81 are inserted through the inner wall of the support leg 4. By rotating the bolts b81, the limitation on the support leg 4 can be released.

[0032] Reference Figures 1-3 The fixing component 5 includes an adjusting plate 51, which is fixedly installed on the outside of the support leg 4 by bolt a54. The length can be adjusted by pulling the length between the adjusting plate 51 and the support leg 4. The adjusting plate 51 and the support leg 4 are both provided with insertion holes 52. They are aligned with each other through the insertion holes 52 and then fixed by bolt a54 and nut. An auxiliary component 53 is sleeved on the outside of bolt a54. The lower part of the auxiliary component 53 is inserted into the inner wall of the insertion hole 52 of the adjusting plate 51 and the support leg 4. With the bolt a54 fixed, the auxiliary component 53 and the bolt a54 together fix the adjusting plate 51 and the support leg 4, ensuring the stability of the connection between the adjusting plate 51 and the support leg 4. The bolt a54 passes through the insertion hole 52 and is fixedly installed by nut.

[0033] Reference Figures 2-4 The limiting component 9 includes a connector 91, which is slidably connected to the inner wall of the slider 3 and inserted into the inner wall of the slot 10. By connecting the connector 91 to the slot 10 and the inner wall of the slider 3, the slider 3 can be locked onto the guide rail 2 for installation. The upper part of the connector 91 is fixedly installed on the inner wall of the slider 3 by a bolt c92. The bolt c92 slides through the inner wall of the slider 3, connecting the connector 91 and the slider 3 together. Both bolt b81 and bolt c92 are provided with torsion caps on their outer sides to facilitate the operator to rotate bolt b81 and bolt c92. The support leg 4 is designed in an S-shape to expand the roller 7 outward, thereby improving the stability of welding movement and reducing vibration. The bending part of the support leg 4 is provided with reinforcing ribs to increase the structural strength of the support leg 4.

[0034] Working principle: In use, the S-shaped support leg 4 is installed on the guide rail 2 on both sides of the gun body 1 via the slider 3. The connector 91 is inserted into the slot 10 of the guide rail 2. The connector 91 can be locked by the bolt c92, thereby locking the slider 3. The bending design of the support leg 4 forms a stable structure similar to a "triangular support" when the support plate 6 and the roller 7 at the end contact the workpiece, which improves the anti-overturning ability and reduces shaking when holding.

[0035] Multiple sets of rollers 7 on the support plate 6 directly contact the workpiece surface, transferring part of the weight of the welding torch from the hand to the workpiece. Physical support replaces the force exerted by the hand, which is especially suitable for vibration suppression in straight welding scenarios. The rollers 7 can roll on the workpiece surface, maintaining support force without affecting the movement of the welding torch along the welding trajectory, achieving a dynamic balance of "support-movement".

[0036] When the angle needs to be adjusted, since the bolt b81 passes through the support leg 4 and is threaded into the adjustment groove 82 of the slider 3, when the bolt b81 is loosened, the support leg 4 can rotate around the rotation point. After adjusting to the angle that adapts to the welding trajectory, the bolt b81 is tightened and enters the corresponding adjustment groove 82 to achieve angle fixation.

[0037] When it is necessary to adjust the length of the support leg 4, since the adjusting plate 51 is connected to the support leg 4 by bolt a54 and auxiliary part 53, use a wrench to loosen bolt a54, remove bolt a54 and auxiliary part 53 together, pull the adjusting plate 51 to change its relative position with the support leg 4, align the insertion hole 52 and insert the auxiliary part 53, and then fix it with bolt a54. The overall length of the support leg 4 can be adjusted to adapt to different welding work.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
