[0024] The upper end of the vertical plate is internally provided with a first channel 11, the cylinder body of the uppermost air cylinder in the through groove of the vertical plate being connected with the lower end of the corresponding first channel 11 through a second hose, the both ends of the horizontal plate are internally provided with second channels 12, the air cylinder in the through groove of the horizontal plate close to the end portion of the horizontal plate being connected with the inner end of the second channel through a third hose, the second channel being connected with the corresponding butt joint 7 through a third channel 13, when the vertical plate is opened to form a ninety-degree angle with the horizontal plate, the upper end of the first channel is butted with the outer end of the second channel.

[0025] The upper end of the first channel and the outer end of the second channel are both fixedly provided with sealing rings, the butting of the upper end of the first channel and the outer end of the second channel through the sealing rings can ensure better air tightness.

[0026] The lower end of the vertical plate is internally provided with a fourth channel, the lowermost cylinder in the through slot of the vertical plate is connected with the upper end of the corresponding fourth channel through a fourth hose, and the lower end of the fourth channel is connected with the corresponding docking port.

[0027] The inner side of the vertical plate is provided with a pad cloth 14, which has a certain elasticity. One end of the pad cloth 14 is fixedly connected with the lower end of the vertical plate, and the other end of the pad cloth is connected with the winding device in the middle of the horizontal plate after passing around the hinge shaft at the hinge joint between the upper end of the vertical plate and the horizontal plate. The telescopic end of the cylinder is fixedly installed with a pressing plate 15, which contacts the outer side of the corresponding pad cloth.

[0028] When the goods 16 are placed inside the locking device, the telescopic end of the cylinder is elongated to push the pad cloth through the pressing plate 15, and the inner side of the pad cloth is pressed against the goods. This design can increase the pressing area when the goods are fixed, and has a certain protective effect.

[0029] A receiving cavity is formed in the bottom of the horizontal plate, and a winding device is arranged in the receiving cavity. The winding device includes a winding roller 17, and the other end of the pad cloth is connected with the winding roller 17.

A threaded hole is formed in the top of the receiving cavity corresponding to the position of the other end of the ratchet tooth 20. An embedded bolt 21 is arranged in the threaded hole. When the bolt 21 is rotated and moved downward, it can push the other end of the ratchet tooth 20, so that one end of the ratchet tooth 20 is disengaged from the ratchet wheel, realizing the reverse rotation of the winding roller. Through this design, the tightness of the pad cloth can be adjusted, for example, at the beginning, the pad cloth is in a relatively relaxed state. When the goods are placed inside the locking device, the user rotates the winding roller by using a tool to cooperate with the internal hexagonal hole, so that the pad cloth is pre-tightened. Then the cylinder is elongated to clamp the goods inside the locking device through the relatively tight pad cloth. This design can be applied to some irregular goods. The cooperation of the cylinder, the pressing plate and the pad cloth can better wrap the goods, realizing the fixation of the goods.

[0030] It also includes a sealing cover matched with the docking head. The docking head can be closed through the sealing cover.

[0031] It also includes a bottom plate 22, which is provided with a positioning groove 23 matched with the docking block. The positioning groove 23 is provided with a gas supply head 24 connected with the gas supply device. The gas supply head 24 can be docked with the docking port 9 of the docking block.
