Example 2

Please refer to FIG. 9 to FIG. 14 , this embodiment is an improved solution of Embodiment 1. There is a valve channel 461 inside the second block 48 , and the second block 48 is open at one end close to the first cavity 41 to communicate with the first cavity. 41. The opposite end of the second block 48 is provided with a valve slot 462 communicating with the valve channel 461. The valve slot 462 is divided into a vertical section (not marked) and a horizontal section (not marked). One end of the horizontal section is connected to the valve slot 462, and the other One end connects to the vertical segment. The fourth block 458 is arranged in the vertical section, and the outside of the second block 48 is provided with an opening connecting the vertical section away from the end of the horizontal section. Then, by the air pressure in the valve passage 461, the fourth block 458 can be realized relative to the vertical. Straight segment to move.

In the second slot 15, there is a fourth slot 459 for the fourth block 458, so that the second block 48 can be locked and fixed in the second slot 15, so that The installation of the second frame body 3 in the second slot 12 is more stable.

In order to realize the pneumatic transmission of the fourth clamping block 458, in this embodiment, a fourth cavity 451 parallel to the extending direction of the plate body is provided in the sealing plate 45, and the top of the sealing plate 45 has an opening communicating with the fourth cavity 451.
