The polygonal head 9 is convenient for the user to rotate it with the help of a wrench to rotate the screw rod 8, and the guide rod 10 improves the stability of the lifting plate 6 in the up and down movement.

[0019] The front and rear edges of the lifting plate 6 and the corners near the extension plate 12 are respectively fixedly connected with connecting plates 13, and the connecting shaft 15 is fixedly connected between the two supporting plates 14, and the two ends of the connecting shaft 15 are respectively rotated to penetrate the surface of the connecting plate 13. The two supporting plates 14 can rotate together with the connecting shaft 15 as the axis.

[0020] A connecting rod 16 is fixedly connected between the two supporting plates 14 and on one side away from the connecting shaft 15. The connecting rod 16 facilitates the user to rotate the two supporting plates 14, and also increases the structural strength between the two supporting plates 14.

[0021] The elastic mechanism includes a telescopic rod 17 rotatably connected to the lower sides of the two support plates 14, a rotating cylinder 18 is slidably sleeved on the lower end of the telescopic rod 17, an anti-slip disk 20 is fixedly connected to the lower end of the telescopic rod 17, the anti-slip disk 20 slides with the inner wall of the rotating cylinder 18, a compression spring 19 is provided on the inner side of the rotating cylinder 18, and the compression spring 19 is located on the lower surface of the anti-slip disk 20, and the lower end of the rotating cylinder 18 is rotatably connected to the upper surface of the fixed plate 5.

[0022] The lower sides of the two support plates 14 are fixedly connected to a top seat 21, the upper end of the telescopic rod 17 is fixedly connected to an upper rotating shaft 22, the upper rotating shaft 22 is rotatably connected to the top seat 21, the lower end of the rotating cylinder 18 is fixedly connected to a lower rotating shaft 24, the outer surface of the lower rotating shaft 24 is rotatably sleeved with a lower seat 23, and the lower seat 23 is fixedly mounted on the upper surface of the fixed plate 5. This part of the design ensures that when the telescopic rod 17 slides relative to the rotating cylinder 18, the upper end of the telescopic rod 17 and the lower end of the rotating cylinder 18 will not get stuck.

[0023] The second lifting mechanism includes a support frame 25 fixedly mounted on the upper surface of the moving plate 1, the upper end of the support frame 25 is fixedly connected to a bottom plate 26, a threaded rod 27 is threadedly penetrated through the upper surface of the bottom plate 26, a swivel head 28 is fixedly connected to the lower end of the threaded rod 27, a concave seat 30 is rotatably connected to the upper end of the threaded rod 27, a stabilizing rod 29 is fixedly connected to the lower surface of the concave seat 30 and the side away from the threaded rod 27, the lower end of the stabilizing rod 29 slides through the upper surface of the bottom plate 26, a roller shaft 32 is fixedly penetrated through the middle axis of the roller 31, and the two ends of the roller shaft 32 are respectively rotatably penetrated through the inner surface of the concave seat 30. The swivel head 28 facilitates the user to rotate the threaded rod 27 with the help of a wrench, and the stabilizing rod 29 improves the stability of the concave seat 30 during the up and down movement.

[0024] Universal wheels 2 are respectively installed at the corners of the lower surface of the movable plate 1, so that the user can push the movable plate 1 conveniently.

[0025] During installation, the extension tube 33 is placed on the ground, and then the lower end of the docking elbow 34 is put on, and then the front end of the lower bend tube 35 is inserted into the rear end of the docking elbow 34, and then the movable plate 1 is pushed under the docking elbow 34, and the lifting plate 6 holds up the lower surface of the docking elbow 34, and the fixed angle block 11 and the support plate 14 respectively hold the two sides of the lower surface of the docking elbow 34, and the roller 31 holds up the rear lower end surface of the lower bend tube 35 to achieve stable positioning, and then the user holds the welding gun mechanism 3 to weld the connection between the lower bend tube 35 and the docking elbow 34, and the connection between the extension tube 33 and the docking elbow 34, which plays the function of auxiliary welding. In the welding of a batch of barb-type pipe bodies, the consistency of the welding points can be maintained to avoid excessive differences during welding.

[0026] In the above positioning, when the movable plate 1 moves, first use force to bend the connecting rod 16, and insert the telescopic rod 17 into the rotating cylinder 18, so that the compression spring 19 is squeezed and pressed down until the upper end of the support plate 14 is not higher than the plane of the upper surface of the fixed plate 5, so as to ensure that the fixed plate 5 can be moved horizontally to the lower surface of the docking elbow 34. After letting go, under the elastic force of the compression spring 19, the support plate 14 rotates and resets. Due to the presence of the anti-slip disc 20, the support plate 14 is limited when the lower side is rotated to the horizontal. The support plate 14 cooperates with the fixed angle block 11 on the other side to limit the two sides of the lower surface of the docking elbow 34, which can help the docking elbow 34 to be straightened along the front and rear directions. The operation is convenient and the limiting is stable.

[0027] By rotating the screw rod 8, the lifting plate 6 can be moved up and down to ensure that the fixed plate 5 can stably support the docking elbow 34. The insertion depth of the extension tube 33 into the lower end of the docking elbow 34 can be changed by adjustment. By rotating the threaded rod 27, the concave seat 30 can be moved up and down to ensure support for the end face of the lower bend pipe 35. The depth of the insertion of the front end of the lower bend pipe 35 into the rear end of the docking elbow 34 can be changed by adjustment. The use and adjustment are flexible and convenient.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
