Since the positive thread 1 is threadedly connected to the positive thread hole 1, and the negative thread 1 is threadedly connected to the negative thread hole 1, when the bidirectional threaded rod 1 401 rotates, the two adjustment plates 3 can be driven to move in opposite directions at the same time, so that the position of the positioning component 2 can be adjusted.

[0026] See also Figure 1-2 There are two positioning components 2, and the two positioning components 2 are respectively arranged on the two adjustment plates 3 through the rotating blocks 5, the rotating blocks 5 penetrate the adjustment plates 3, and the rotating blocks 5 and the adjustment plates 3 are rotatably connected through the bearings.

The driving component 2 6 includes a pair of rotating components 201 arranged in the positioning frame 201. The positioning frame 201 is provided with a second positive threaded rod 601, and two clamping blocks 202 are threadedly rotatably sleeved on the second bidirectional threaded rod 601. The second bidirectional threaded rod 601 is provided with a second positive threaded rod and a second negative threaded rod, and the threads of the second positive threaded rod and the second negative threaded rod are opposite. One clamping block 202 is provided with a second positive threaded hole for the second positive threaded rod to rotate, and the other clamping block 202 is provided with a second negative threaded hole for the second negative threaded rod to rotate.

[0029] The working principle of this utility model:

[0030] When the pressure vessel needs to be positioned, the pressure vessel is first moved between the two positioning assemblies 2, and then the motor 1 402 can be started, thereby driving the bidirectional threaded rod 1 401 to rotate, so that the two adjustment plates 3 move toward the direction of the pressure vessel. After moving to the appropriate position, the motor 1 402 can be turned off, and then the motor 2 602 can be started, thereby driving the bidirectional threaded rod 2 601 to rotate, so that the two clamping blocks 202 move toward the direction of the pressure vessel, thereby clamping the pressure vessel. After clamping the pressure vessel, the motor 2 602 is turned off, and then the motor 3 can be started, thereby driving one of the clamping rods 701 to rotate, so that the other clamping rod 701 also rotates in the opposite direction, thereby clamping the pressure vessel and positioning the pressure vessel.

[0031] When the direction of the pressure vessel needs to be rotated, the motor four 804 can be started, which can drive the gear 801 to rotate, so that one of the rotating blocks 5 also rotates. Since the two positioning components 2 clamp the pressure vessel, the pressure vessel, the two positioning components 2, and the other rotating block 5 also rotate, so that the direction of the pressure vessel can be adjusted. After adjusting to the appropriate direction, the motor four 804 can be turned off.
