[0125] In some specific embodiments of the utility model, the pressing block 220 can be two, which are arranged side by side, so as to further expand the pressing area and make the quick change part 130 closely adhere to the first side wall 200.

[0126] In some specific embodiments of the utility model, the pressing block 220 can be driven by a spring, which can not only maintain the pressing force and maintain the sealing effect, but also reduce the occupied space and does not need to introduce additional power.

[0127] In some specific embodiments of the utility model, the pressing block 220 can be installed on a guide column, and the spring is sleeved on the guide column, so as to simplify the installation and arrangement.

[0128] In some specific embodiments of the utility model, the second side wall 210 can have a stepped portion, which limits the pressing block 220, so as to reserve enough space between the pressing block 220 and the first side wall 200, and facilitate the installation of the quick change part 130.

[0129] In some specific embodiments of the utility model, the second side wall 210 can have a mounting hole, which is provided with a stepped portion and a mounting strip for mounting the guide column. The mounting strip can be connected to the side wall of the mounting hole, so as to simplify the installation and maintenance of the pressing block 220.

[0130] In some specific embodiments of the utility model, the second side wall 210 can be provided with a mounting portion on the side away from the first side wall 200, which is used for the installation of the body 100.

[0131] Because the slot 190 is arranged, the quick-change part 130 does not occupy the position of the second side wall 210 which is away from the first side wall 200, so that the mounting portion is conveniently arranged, and the installation arrangement requirement is met.
