Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, Figure 2, Figure 3a and Figure 3b, this embodiment includes a female joint assembly 1, a male joint assembly 2, a gas cylinder base 3, a locking device 4, a high-pressure gas cylinder 5, a fixing plate 6, and a compression spring 7. Propelling plate 8, traction block 9, flat plate 10; wherein, female joint assembly 1 includes connecting cylinder bolt 101, female quick joint 102, locking sleeve 103, male joint assembly 2 includes male quick joint 201, air pipe joint 202, There is a buckle 401 at the left and right ends of the clamping device 4. At the end of the gas cylinder base 3, there is a pair of notches 301 corresponding to the buckle 401. There is a self-locking switch 801 in the middle of the push plate 8; 101 is connected to the female quick connector 102, and the locking sleeve 103 is placed on the end ring of the female quick connector 102, which can slide left and right; the gas pipe connector 202 is fixedly connected to the end of the male quick connector 201, and can be connected with a hose; the gas cylinder base 3 is The V shape is placed on the flat plate 10, and there is a section of hollow guide rail inside the bottom end; the locking device 4 is horizontally inverted L-shaped, placed at the bottom end of the gas cylinder base 3, and connected with the guide rail, and can slide left and right; the fixed plate 6 Right in front of the gas cylinder base 3 and fixed on the flat plate 10, the male quick joint 201 is fixed on the left fixed plate; the traction block 9 is symmetrically distributed at the end of the male quick joint 201, and passes through the two fixed plates 6 The two ends of the compression spring 7 are fixed on the right fixed plate and the inside of the self-locking switch 801, and the self-locking switch 801 is reset by the elastic force of the compression spring 7, and the pushing plate 8 can be moved by squeezing the compression spring 7.
