[0023] The outer side of the threaded rod b18 is threadedly connected with the rack rod 19, the top of the rack rod 19 is meshingly connected with the gear rod b16, and the outer side of the gear rod b16 is meshingly connected with the gear rod a15; the adjusting mechanism 20 comprises a threaded rod c201 fixedly connected with the bottom of the connecting seat 14, and a threaded sleeve 207 threadedly connected with the outer side of the threaded rod c201; the outer side of the threaded sleeve 207 is movably connected with the support 202 through the bearing, and the bottom of the support 202 is fixedly connected with the moving frame 9; one side of the moving frame 9 is movably connected with the handle 203 through the bearing, one end of the handle 203 is fixedly connected with the bevel gear a204, and the outer side of the bevel gear a204 is meshingly connected with the bevel gear b205; the top of the bevel gear b205 is fixedly connected with the threaded sleeve 207, and the bottom of the bevel gear b205 is slidably connected with the moving frame 9 through the rotating shaft; the inside of the support 202 is slidably connected with the limiting rod 206, the top of the limiting rod 206 is fixedly connected with the connecting seat 14, the inside of the support 202 is provided with the moving groove matched with the limiting rod 206, the limiting rod 206 and the support 202 form a sliding structure, the bevel gear a204 and the bevel gear b205 form a meshing transmission structure, and the threaded rod c201 and the threaded sleeve 207 form a threaded transmission structure.

[0024] In actual implementation, the pressure pipeline needs to be sent to the pressure testing machine after production for pressure test to ensure the quality of the pipeline and the safety of subsequent use. When the pipeline is detected, the pipeline is placed between the two sets of clamping plates 12, and then the two-way threaded rod 11 is rotated to drive the two sets of clamping plates 12 in threaded transmission, so that the clamping plates 12 clamp the pipeline. After clamping is completed, the handle 203 in the adjusting mechanism 20 is rotated to drive the bevel gear a 204 and the bevel gear b 205 to mesh, thereby driving the bevel gear b 205 and the threaded sleeve 207 at the top thereof to rotate.

The central axis of the pipeline coincides with the central axis of the plugging frame a 5 and the plugging frame b 6. Then the motor 7 is started to drive the threaded rod a 8 and the moving frame 9 in threaded transmission, thereby driving the moving frame 9, the plugging frame b 6 and the pipeline to move, so that the other end of the pipeline contacts the plugging frame a 5, and the pipeline is closed.
