[0017] like Figure 1~Figure 4 As shown, a bottom frame is welded with a positioning fixture, including a base 1, a vertical rod 10 is provided on the base 1, a movable sleeve 2 is sleeved on the vertical rod 10, the movable sleeve 2 is installed on the vertical rod 10 by screws 20, a connecting arm 21 is provided on the movable sleeve 2, and a rectangular plate 3 is provided at the other end of the connecting arm 21. Specifically, the rectangular plate 3 is rotatably arranged on the other end of the connecting arm 21.
[0018] At least four mounting seats 5 are provided on the rectangular plate 3, and a positioning inner plate 4 is installed on the mounting seat 5. A positioning end plate 40 is provided at the outer end of the positioning inner plate 4. A pair of rotating shafts are rotatably provided at the inner end of the positioning inner plate 4. A top wheel 49 is eccentrically provided at the outer end of the rotating shaft. A swing plate 41 is provided at the inner end of the rotating shaft. A pull rod 42 is provided at the other end of the swing plate 41. A lug 50 is provided at the inner end of the positioning inner plate 4. A screw rod 48 is rotatably provided on the lug 50. A rotating cap is provided at the outer end of the screw rod 48. A moving seat 46 is provided on the screw rod 48. A concave plate 44 is provided on the inner side of the moving seat 46. An action hole 45 is opened on the vertical section of the concave plate 44, and the pull rod 42 passes through the action hole 45.
[0019] At least four pairs of guide holes 30 are provided on the rectangular plate 3, and connecting rods 31 are passed through the guide holes 30. Each pair of connecting rods 31 is arranged on the mounting seat 5. An L-shaped plate 32 is provided at the other end of the connecting rod 31. A rotating top plate 33 is rotatably provided between the L-shaped plates 32. A handle 34 is provided at the outer end of the rotating top plate 33. The inner end of the rotating top plate 33 is in a semicircular arc structure. An active top plate 35 is sleeved on the connecting rod 31.
