[0050] In the embodiment, the compression assembly 1 has a compression direction and a loosening direction opposite to each other, wherein the compression direction is the moving direction of the pressing structure 13 when the pressing structure 13 actively compresses the compressed device 200, and the loosening direction is the moving direction of the pressing structure 13 when the pressing structure 13 loosens the compressed device 200.
[0051] The mounting base 11 of the compression assembly 1 serves as the mounting base of the compression assembly 1, and when the compression assembly 1 is applied, the compression assembly 1 is fixed on the mounting position by fixing the mounting base 11, and the mounting base 11 can be fixed by bolt locking, bonding, clamping and the like. The mounting base 11 is provided with a guide hole 111 penetrating through both the compression direction and the loosening direction, the pressing structure 13 is arranged in the guide hole 111, the pressing structure 13 extends along the axial direction of the guide hole 111 and can be a columnar structure, a cuboid structure or other long strip-shaped structure, and the pressing structure 13 has two ends arranged oppositely, one end of which is arranged as a pressing end and protrudes out of the guide hole 111 for supporting and pressing the compressed device 200, and the other end of the pressing structure 13 is arranged as a pressure receiving end. The pressing structure 13 can be an integral structure or formed by connecting at least two separate structures, for example, the pressing structure 13 is formed by combining a pressing member 131 and a pressure head 132 in the following embodiment.
[0052] The compression assembly 1 further comprises a cam wrench 12 and a pushing structure 14 for driving the pressing structure 13 to move, and the cam wrench 12 applies pressure to the pressure receiving end of the pressing structure 13 through the pushing structure 14. Specifically, the pushing structure 14 comprises a pushing member 142 and a driving member 141 connected with each other, the pushing part 1422 of the pushing member 142 abuts against the pressure receiving end of the pressing structure 13, and part of the structure of the driving member 141 protrudes out of the guide groove 112 of the side wall of the mounting base 11 as a driving part 1411.
[0053] The cam wrench 12 comprises a cam structure 121 and a wrench structure 122 connected with each other, the cam structure 121 is rotationally connected with the mounting base 11, and the cam structure 121 abuts against the driving part 1411; the wrench structure 122 can lengthen the rotating force arm of the cam wrench 12, and a smaller force can be used to drive the cam wrench 12 to rotate to apply a larger pressure to the driving part 1411.
