positioning holes are formed in the connected workpiece 3 and the gasket 4, correspond to accommodating cavities formed in the connecting workpiece 2 and are located on the same axis;

an accommodating cavity is formed in the connecting workpiece 2, and a custom bolt 9 is matched in the accommodating cavity;

and the first floating plate 11 is fixedly provided with threads at the position corresponding to the accommodating cavity formed on the connecting workpiece 2.

In the embodiment, the relative distance between the connecting workpiece 2 and the connected workpiece 3 is less than 10 mm.

In this embodiment, the end of the customized bolt 9 is located in the accommodating cavity, and the tail end of the customized bolt 9 is inserted into the positioning hole.

In this embodiment, the end of the customized bolt 9 is a concave groove, the customized bolt 9 is connected with the connecting rod 10 in a matching manner, and one end of the connecting rod 10 is inserted into the concave groove at the end of the customized bolt 9.

In this embodiment, one end of the connecting rod 10 is a concave groove, the connecting rod 10 is fixedly matched with the motor 12, and the motor 12 is inserted into the concave groove at one end of the connecting rod 10.

In this embodiment, the screw 8 is vertically symmetrical at one end of the connection workpiece 2 connected with the floating plate 11, the floating plate 11 is sleeved on the screw 8 to prop against the spring 7, the spring 7 is sleeved on the screw 8, the other end of the screw 8 is fixed on a spring baffle 13 on the motor 12, and the spring baffle 13 is fixedly connected with the motor 12.

In this embodiment, a threaded connection section is fixedly disposed at the middle position of the connection rod 10 and below the concave groove, and the threaded connection section is matched with a thread fixedly disposed on the first floating plate 11.

In this embodiment, the customized bolt 9 is sleeved on the lower portion of the connection rod 10, and the end face of the customized bolt 9, which is in contact with the first floating plate 11, is fixed with magnetism.
