DETAILED DESCRIPTION
[0018] 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.
[0019] A replacement bracket for an automobile idle pulley, such as Figure 1-Figure 4As shown, it includes a pulley 1, a connecting disk 2, a telescopic frame 3, a first torsion spring 4, a rotating plate 5, a second torsion spring 6, a clamping column 7, a motor 8, a sleeve 9, a connecting frame 10, a handle 11 and a docking frame 12. The left part of the connecting disk 2 is rotatably connected to the clamping column 7, the sleeve 9 is clamped on the clamping column 7, the pulley 1 is clamped on the left side of the sleeve 9, the front and rear sides of the connecting disk 2 are rotatably connected to the telescopic frame 3, the upper and lower sides of the telescopic frame 3 are connected to the connecting disk 2 with the first torsion spring 4, the left part of the telescopic frame 3 is rotatably connected to the rotating plate 5, the upper and lower sides of the rotating plate 5 are connected to the adjacent telescopic frames 3 with the second torsion spring 6, the right side of the middle part of the connecting disk 2 is connected, the output shaft of the motor 8 is connected to the clamping column 7, the upper side of the connecting disk 2 is rotatably connected to the connecting frame 10, the upper part of the connecting frame 10 is clamped with the handle 11, the right side of the connecting disk 2 is connected to the docking frame 12, and the motor 8 is connected to the docking frame 12.
[0020] When using the device, first carry the device to the replacement area of the empty pulley 1 of the automobile, then extend it through the telescopic frame 3, then rotate the telescopic frame 3, the first torsion spring 4 is deformed, and then the sleeve 9 is docked with the screw on the pulley 1. After the docking is completed, loosen the telescopic frame 3, so that the rotating plate 5 contacts the pulley 1, driving the rotating plate 5 to rotate, the second torsion spring 6 is deformed, clamping the pulley 1, and then fix the docking bracket 12 on the bracket, and then start the motor 8. The operation of the motor 8 drives the clamping column 7 to rotate, and then drives the sleeve 9 to rotate, and then drives the screw on the pulley 1 to rotate. The screw is moved on the pulley 1, thereby driving the pulley 1 to move, and the pulley 1 is disassembled and replaced. When the screws on different pulleys 1 need to be removed, the sleeve 9 can be removed so that the sleeve 9 is no longer engaged with the clamping column 7, and then the sleeve 9 of the corresponding screw is clamped on the clamping column 7, so that the screws on different pulleys 1 can be removed, and the pulley 1 can be moved out while the screw is being removed, saving manpower, improving work efficiency, and improving the flexibility of using the device. After the pulley 1 is moved out, the handle 11 on the connecting bracket 10 is held to drag the pulley 1 out.
