s3 discharging: after the inflation is finished, the driving device 66 is controlled to move the mounting plate 63 to the highest position, and at the moment, the tank body is loosened by rotating the adjusting rod 81.

The working principle is as follows:

the two clamping blocks 21 are connected to the upper end of the workbench 1 in a sliding mode, the ejector rods 22 are arranged on the clamping blocks 21, the first rotating rod 26 and the second rotating rod 32 are driven to rotate when the tank body is clamped by the clamping blocks 21, so that the descending path of the mounting plate 63 is released by the first baffle plate 4 and the second baffle plate 5, the tank body can be inflated only by descending the mounting plate 63 after the tank body is clamped, and the phenomenon that an operator often forgets to fix the tank body before inflation, so that the tank body runs when inflated, and safety accidents are caused is avoided; the linkage mechanism 7 is arranged at the lower end of the workbench 1, so that the two clamping blocks 21 synchronously and reversely move, the two clamping blocks 21 can perform centering clamping on the tank body, and the inflation head 64 can be aligned to the tank body to complete inflation; in addition, the synchronous reverse motion of the two clamping blocks 21 enables an operator to control only one clamping block 21 to move, so that the two clamping blocks 21 can move simultaneously, the operation of the operator is facilitated, and the convenience is improved; the locking mechanism 7 is arranged on the workbench 1 to control the movement opportunity of the clamping block 21, so that the phenomenon that the tank body is loosened by misoperation of an operator when the tank body is inflated to cause the tank body to run under the action of air pressure to cause safety accidents is avoided.
