When the at least one fastener 53 is rotated in the direction of tightening the at least one fastener 53, the at least one fastener 53 drives the first pressing plate 10 to move in the direction close to the second pressing plate 20, and squeezes the at least one elastic member 55 at the same time, and at this time, the at least one elastic member 55 is in a compressed state. When the at least one fastener 53 is rotated in the opposite direction, the at least one fastener 53 moves in the direction away from the second pressing plate 20, and the at least one elastic member 55 in the compressed state drives the first pressing plate 10 to move in the direction away from the second pressing plate 20.

[0082] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention is described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
