[0028] As a specific embodiment of a pressure hose pressure testing device provided in the application, the driving member 5 is a ball screw mechanism, and the driving member 5 includes a screw rod 51, and the screw rod 51 is threadedly connected to the fixed platform 31 and the mounting platform 41, and the threads of the screw rod 51 connecting the fixed platform 31 and the mounting platform 41 are opposite to each other.

[0029] Overall, through mutualThe reverse thread causes the fixed platform 31 and the mounting platform 41 to move in opposite directions, that is, closer or farther away, when the driving member 5 is in operation. The movement of the fixed platform 31 and the mounting platform 41 is controlled by one driving member 5, the mechanism is simplified, and the ball screw mechanism can usually be self-locking, and is self-locking and fixed after the pressure test tube 32 forms a seal with the joint of the pipe to be tested.
