[0031] Specifically, the support plates 5 are used as the basic part of the whole structure, and they stand opposite to each other to support and fix other components. On their adjacent sides, support blocks 25 are firmly connected. These support blocks 25 not only enhance the stability of the support plates 5, but also serve as connection points for other components. The outer wall of the inclined plate 1 23 is slidably connected to the inclined plate 2 24, which means that the inclined plate 1 23 can move relative to the inclined plate 2 24, thereby changing the angle between the two.

By adjusting the angle between the inclined plate 1 23 and the inclined plate 2 24, as well as the position of the movable plate 22 in the hollow square plate 2 19, adjustments of different angles and positions can be achieved to meet different usage requirements.

[0032] Please see attached Figure 2The alignment mechanism 2 includes a fixed plate 202, the bottom end of the fixed plate 202 is fixedly connected to the top surface of the workbench 1 near the edge, the adjacent sides of the two fixed plates 202 are fixedly connected with a telescopic rod 201, the output end of the telescopic rod 201 is fixedly connected with an inclined rod 211, the top front side of the workbench 1 is fixedly connected with a U-shaped plate 203, the middle part of the top surface of the U-shaped plate 203 is provided with a long slide groove 204, the inner side of the long slide groove 204 is slidably connected with the outer wall of the inclined rod 211, the other end of the inclined rod 211 is fixedly connected with an H-shaped plate 205, the top rear side of the workbench 1 is fixedly connected with A T-shaped block 207 is provided with a T-shaped groove 208 in the middle of the top surface of the T-shaped block 207, and an H-shaped groove 209 is slidably connected to the inner side of the T-shaped groove 208, and the top of the H-shaped groove 209 is fixedly connected to the bottom end of the support plate 5, and the top of the H-shaped groove 209 is fixedly connected to the outer side of the long plate 210, and a T-shaped groove 206 is provided on the outer wall of the long plate 210, and the inside of the T-shaped groove 206 is slidably connected to the outer wall of the H-shaped plate 205, and the adjacent sides of the two movable plates 22 are fixedly connected with the clamping plate 21, and the middle part of the inner side of the clamping plate 21 is fixedly connected with the anti-slip pad 20;

[0033] Specifically, the workbench 1 is used as the core of the entire operating platform to carry various processing, assembly or maintenance tasks. Two fixed plates 202 are fixedly connected to the top surface near the edge. The two fixed plates 202 not only provide stable support for other components, but also can flexibly change the position and angle of the inclined rod 211 by adjusting the length of the telescopic rod 1 201 to adapt to different work requirements. This design enables the inclined rod 211 to adjust its position within a certain range, increasing the flexibility of the entire structure. The design of the T-slot 208 allows the H-shaped slide 209 to slide inside it. The top end of the H-shaped slide 209 is fixedly connected to the bottom end of the support plate 5.

[0034] Please see attached Figure 1 - Attachment Figure 2 A handle 6 is fixedly connected to the middle part of the front side of the workbench 1, and fluorescent strips 10 are fixedly connected to the left and right ends of the front side of the workbench 1. An anti-slip plate 4 is fixedly connected to the middle part of the rear side of the top surface of the workbench 1. A lighting lamp 9 is fixedly connected to the top of the rear side legs 8 near the edge. The two lighting lamps 9 are symmetrically designed. A battery 11 is fixedly connected to the left side of the left leg 8. A limited block 15 is fixedly connected to the adjacent side of the L-shaped plate 14. A limited block 13 is fixedly connected to the front side of the square plate 12. A controller 3 is fixedly connected to the left side of the top surface of the workbench 1. The controller 3 is electrically connected to the lighting lamp 9, the telescopic rod 1 201, the battery 11 and the telescopic rod 2 16 respectively.

[0035] Specifically, fluorescent strips 10 are carefully installed on the left and right ends of the front side of the workbench 1. These fluorescent strips 10 not only add a sense of modernity to the workbench 1, but also provide important safety reminders at night or in dimly lit environments. When workers or operators are active nearby, the fluorescent strips 10 can emit a soft light to help them clearly see the outline of the workbench 1. The two lighting lamps 9 adopt a symmetrical design. The lighting lamps 9 can provide bright and uniform light to help operators better complete their work, and play a role in limiting and stabilizing the sliding of the square plate 12 in the hollow square plate 17. By adjusting the positions of the limit block 13 and the limit block 2 15, the sliding range of the square plate 12 can be accurately controlled to meet different work requirements.

[0036] Working principle: When the valve needs to be welded, first put the valve on the top of the anti-slip plate 4, then cooperate with the L-shaped plate 14 fixedly connected to the support plate 5, and then start the telescopic rod 2 16 fixedly connected to the L-shaped plate 14, so as to pull the L-shaped plate 2 18 to cooperate with the hollow square plate 2 19 and the hollow square plate 1 17 to slide along the outer wall of the square plate 12 and the movable plate 22 at the same time, and cooperate with the inclined plate 1 23 to move forward along the outer wall inclined surface of the inclined plate 2 24 fixedly connected to the support block 25 at the same time, so that the two clamping plates 21 and the anti-slip pad 20 can move relative to each other through the slope between the inclined surfaces to stabilize the valve of the anti-slip plate 4:

[0037] Thereafter, the top end of the H-shaped slide groove 209 is fixed to the support plate 5, and the telescopic rod 201 fixedly connected to the starting plate 202 is coordinated to push the inclined rod 211 to slide along the long slide groove 204 opened on the U-shaped plate 203, so that the H-shaped plate 1 205 slides inside the T-shaped groove 1 206 opened on the long plate 210 at the same time. Therefore, through the inclined design of the inclined rod 211, the H-shaped slide groove 209 can be relatively moved horizontally along the inner side of the T-shaped groove 208, thereby ensuring that the valve is in a stable fitting state during welding.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
