[0030] 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.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a wind-cooled single-axis swing handheld welding gun, including a gun body 1, which is the main structure of the welding gun, supporting and integrating other parts. This technology is prior art, so it will not be described in detail. A handle 2 is provided on the lower side of the gun body 1 for the operator to hold, making the operation more stable and comfortable. The lower side is used to install the output pipe of the air cooler to cool down the welding operation. A shell 3 is provided on the left side of the gun body 1 near the handle 2 to protect the trigger 5 inside. The trigger 5 is provided on the inner wall of the left side of the shell 3 to control the start and stop of the welding gun. This technology is prior art, so it will not be described in detail. A protective component is provided on the left side of the handle 2. The protective component includes a pressing mechanism. The user grips the handle 2, which compresses the pressing plate 41, causing the movable plate 43 to move. The right side of the pressing plate 41 is slidably connected to the inner wall of the left side of the handle 2. The right side of the pressing plate 41 is elastically connected to the handle 2 via a compression spring 42. The elastic force of the compression spring 42 causes the pressing plate 41 to return to its original position, thereby protecting the trigger 5 with the protective plate 46. The movable plate 43 is fixedly connected to the top of the pressing plate 41 and moves with the movement of the pressing plate 41. The outer side of the movable plate 43 is slidably connected to the inner wall of the outer shell 3. A guide groove 44 is provided through the top of the movable plate 43. The guide groove 44 is inclined in opposite directions and can drive the four sets of sliding rods 45 to move.

[0032] Reference Figure 2 - Figure 4 A sliding rod 45 is slidably connected to the inner wall of the guide groove 44. The sliding rod 45, located on the right side of the guide groove 44 near the left side of the moving plate 43, is engaged with the inner wall of the limiting block 48 to limit the protective plate 46 in the unfolded state. The sliding rod 45 on the right side of the moving plate 43 is initially positioned on the right side of the guide groove 44 on the right side of the moving plate 43. The movement of the moving plate 43 drives the two sets of sliding rods 45 to move in opposite directions, thereby squeezing and limiting the protective plate 46 after it is squeezed into the outer shell 3 by the worker, thus limiting the protective plate 46 inside the outer shell 3. Protective plates 46 are provided on both the front and rear sides of the outer shell 3 near the trigger 5 to protect the trigger 5 and prevent accidental activation. The outer side of the protective plate 46 is slidably connected to the inner wall of the outer shell 3.

[0033] Furthermore, the upper right inner wall of the protective plate 46 is elastically connected to the outer shell 3 via a return spring 47, providing a leftward return force to the protective plate 46. When the limit on the protective plate 46 is released, the protective plate 46 can quickly return to its original position, thereby protecting the trigger 5. A limit block 48 is fixedly connected to the front side of the protective plate 46. Two sets of limit blocks 48 are provided, with a groove on the side near the slide rod 45. The slide rod 45 slides into the groove to limit the protective plate 46. The rear side of the slide rod 45 slides on the inner wall of the front side of the limit block 48. The slide rod 45 is T-shaped. The T-shape improves the stability of the slide rod 45 when it slides on the inner wall of the outer shell 3. Multiple sets of slide rods 45 and multiple sets of guide grooves 44 are provided, which can simultaneously limit the two sets of protective plates 46. The multiple sets of guide grooves 44 are inclined to guide the movement direction of the slide rod 45.

[0034] Reference Figure 2 , Figure 3 and Figure 5 A limiting component is provided on the inner wall of the front side of the grip 2. The limiting component includes a slide groove 61, which provides limiting and guidance for the movement of the slide plate 62. The slide groove 61 is opened on the front side of the grip 2, and the slide plate 62 is slidably connected to the inner wall of the slide groove 61. When the worker operates, the slide plate 62 can be pushed upward by the thumb to quickly release the limiting of the pressing plate 41. The top of the slide plate 62 is elastically connected to the slide groove 61 by a compression spring 63. The compression spring 63 is initially in a compressed state. By the elastic force of the compression spring 63, the pressing plate 41 can be automatically limited when the worker presses the pressing plate 41. A limiting plate 64 is fixedly connected to the left side of the slide plate 62, which limits the pressing plate 41 by snapping into the inner wall of the limiting groove 65.

[0035] Furthermore, the inner side of the limiting plate 64 slides on the outer side of the handle 2, and the inner wall of the pressing plate 41 is provided with a limiting groove 65 for limiting or releasing the pressing plate 41. The outer side of the limiting plate 64 slides on the inner wall of the limiting groove 65, which is L-shaped. When the pressing plate 41 is in the initial unpressed state, the limiting plate 64 is located at one end of the upper side of the L-shape of the limiting groove 65. When the pressing plate 41 is pressed, the pressing plate 41 moves a certain distance, and the limiting plate 64 slides along the L-shape of the limiting groove 65. Through the elastic force of the compression spring 63, the limiting plate 64 is driven to slide downward along the limiting groove 65, thereby limiting and positioning the pressing stroke of the pressing plate 41, thus ensuring the normal operation of the protective components and the entire welding gun.

[0036] Working principle: In the normal non-use state, the protective plate 46 extends out of the outer shell 3 under the elastic force of the return spring 47, which protects the trigger 5 and prevents accidental activation. When the operator holds the handle 2 to prepare for welding operation, the fingers will squeeze the pressing plate 41, the pressing plate 41 moves to the right, the compression spring 42 is compressed, and at the same time the pressing plate 41 drives the moving plate 43 to move.

[0037] Since the guide groove 44 at the top of the movable plate 43 is inclined, the movement of the movable plate 43 will cause the slide rod 45 to slide along the guide groove 44, so that the slide rod 45 slides out from the groove of the limiting block 48, releasing the limitation on the protective plate 46. Under the pressure of the operator, it is retracted into the outer shell 3 and the trigger 5 is pressed to perform welding operations. When the protective plate 46 is fully retracted, the movable plate 43 will drive the slide rod 45 on its right side to slide into the groove of the limiting block 48 on the front side of the protective plate 46, limiting the protective plate 46 and keeping it in the retracted state.

[0038] During the pressing and moving process of the pressing plate 41, the limiting plate 64 slides along the L-shaped path of the limiting groove 65. After the pressing plate 41 moves a certain distance, the elastic force of the compression spring 63 will cause the limiting plate 64 to slide down along the limiting groove 65, thereby limiting and positioning the pressing stroke of the pressing plate 41.

[0039] When the welding work is completed, the operator pushes the slide plate 62 upward with his thumb to compress the compression spring 63, which moves the limit plate 64 upward. Then, he releases his finger from the pressure plate 41, and the elastic force of the compression spring 42 causes the pressure plate 41 to return to its original position, which causes the moving plate 43 to move in the opposite direction. The slide bar 45 on the right side of the moving plate 43 slides out of the groove of the limit block 48, and the elastic force of the return spring 47 causes the protective plate 46 to extend out of the outer shell 3, thus protecting the trigger 5 again.

[0040] 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.
