[0007] The welding platform is fixedly connected with rotating shafts on both sides, and the two rotating shafts are rotatably connected to the inside of the support column. The bottom of the welding platform is fixedly connected with a rack, and the rack is set as a circular ring structure. The inside of the base is rotatably connected with a worm, and the outer side of the worm and the outer side of the rack are meshed with each other to form a worm gear transmission structure. The end of the worm is fixedly connected with a handle A;

[0008] A clamping structure for fixing the object is provided on the top of the welding table.

[0009] Furthermore, the base is provided with an opening and a slot inside, and the rack is located in the opening and the slot inside the base.

[0010] Furthermore, a cushion block is fixedly connected to the top of the welding table, and a fixed block is fixedly connected to the top of the welding table on one side of the cushion block, two moving shafts are symmetrically slidably connected inside the fixed block, and a fixed ring is fixedly connected to the top of the fixed block, a screw rod is rotatably connected inside the fixed ring, and a handle B is fixedly connected to the end of the screw rod.

[0011] Furthermore, the clamping structure is provided with a shear arm A, the outer side of the moving shaft is rotatably connected to the shear arm A, and a connecting hole is provided at the connection between the shear arm A and the moving shaft, the bottom of the shear arm A is fixedly connected to the connecting shaft, and the outer side of the connecting shaft is rotatably connected to the shear arm B, and a rotating hole is provided at the connection between the shear arm B and the connecting shaft, a shear structure is formed between the shear arm A and the rotating hole, and the end of the shear arm B is rotatably connected to the moving shaft through the connecting hole.

[0012] Furthermore, a mounting hole is provided at the top of the shear arm A, and a drive sleeve is rotatably connected inside the mounting hole. The drive sleeve, mounting hole, connecting shaft and rotating hole are located on the same vertical line. A thread is provided inside the drive sleeve, and the thread inside the drive sleeve is connected to the outside of the screw rod.

[0013] Furthermore, the ends of the shear arm A and the shear arm B away from the connecting hole are both rotatably connected to a driving slider, and the outer side of the driving slider is slidably connected to a clamping block, and two symmetrically distributed sliders are provided at the bottom of the clamping block.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The wall clock welding device with a semicircular slope limit structure is provided with a rack. The user operates the handle A to drive the worm to rotate inside the base. Since the outer side of the worm is in meshing relationship with the rack, this rotation action will further cause the worm to drive the rack to move outside it. Subsequently, the rack will drive the welding table to rotate inside the support column through two rotating shafts, thereby realizing the adjustment of the inclination angle of the welding table.

[0018] Furthermore, the outer side of the worm and the outer side of the rack mesh with each other to form a worm gear transmission mechanism. When the worm drives the rack to move on its outer side, if the user stops rotating the worm, due to the characteristics of the worm gear transmission mechanism, the meshing between the outer side of the worm and the outer side of the rack will form a self-locking structure. This self-locking structure can effectively fix the position of the rack on the outer side of the worm, thereby achieving stable fixation of the tilt angle of the welding table;

[0019] Furthermore, a clamping structure is provided, and the user operates handle B to drive the screw to rotate inside the fixed ring. Subsequently, the screw will drive the driving sleeve to move outside it. During the movement of the driving sleeve, it will cause the connection between the shear arm A and the shear arm B to be displaced, causing the shear arm A and the shear arm B to rotate around the center of the shear arm B, thereby generating a shearing action. This action will cause the end driving sliders of the shear arm B and the shear arm A to perform relative reverse movement. While the driving slider slides inside the clamping block, it will also push the clamping block to slide in the positioning groove on the top of the pad block. This mechanism controls the clamping or release state between the clamping block and the object. During the mutual rotation of the shear arm B and the shear arm A, both will drive the moving shaft to slide inside the fixed block. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The user operates the handle A7 to drive the worm 6 to rotate inside the base 1. Since the outer side of the worm 6 is in meshing relationship with the rack 5, this rotational action will prompt the worm 6 to drive the rack 5 to move on its outer side. Subsequently, the rack 5 will drive the welding table 3 to rotate inside the support column 2 through the two rotating shafts 4, thereby adjusting the inclination angle of the welding table 3; the outer side of the worm 6 and the outer side of the rack 5 are meshed with each other to form a worm gear transmission mechanism. When the worm 6 drives the rack 5 to move on its outer side, if the user stops rotating the worm 6, due to the characteristics of the worm gear transmission mechanism, the meshing between the outer side of the worm 6 and the outer side of the rack 5 will form a self-locking structure. This self-locking structure can effectively fix the position of the rack 5 on the outer side of the worm 6, thereby achieving stable fixation of the inclination angle of the welding table 3.

[0031] The user operates the handle B13 to drive the screw rod 12 to rotate inside the fixed ring 11. Then, the screw rod 12 will drive the drive sleeve 22 to move outside it. During the movement of the drive sleeve 22, it will cause the connection between the shear arm A14 and the shear arm B17 to be displaced, causing the shear arm A14 and the shear arm B17 to rotate around the center of the shear arm B17, thereby generating a shearing action. This action will cause the end driving sliders 19 of the shear arm B17 and the shear arm A14 to move in opposite directions. While the driving slider 19 slides inside the clamping block 20, it will also push the clamping block 20 to slide in the positioning groove 23 on the top of the pad 8. This mechanism controls the clamping or loosening state between the clamping block 20 and the object. During the mutual rotation of the shear arm B17 and the shear arm A14, both will drive the moving shaft 10 to slide inside the fixed block 9.
