[0032] As a preferred solution of the utility model, the adjustment mechanism includes: two unlocking plates 10, four pull rods 12, two transmission plates 13, two cross plates 16 and four card blocks 18; the two unlocking plates 10 and the transmission plates 13 are slidably connected to the top of the corresponding fixed frame 7, the four pull rods 12 are symmetrically connected to the top of the corresponding transmission plate 13, the two cross plates 16 are respectively slidably connected to the top of the corresponding fixed frame 7, the bottoms of the four pull rods 12 are respectively connected to the top of the corresponding unlocking plates 10 and the cross plates 16, and the four card blocks 18 are respectively fixedly connected to the corresponding one of the two unlocking plates 10 and the cross plates 16. On the other hand, the left and right sides of the two adjusting rods 8 are symmetrically provided with card slots, and the card blocks 18 are adapted to the corresponding card slots. When the unlocking plate 10 moves horizontally, the card block 18 on the left side will be driven to move horizontally. At the same time, the movement of the unlocking plate 10 will pull the pull rod 12 on the left side. The movement of the pull rod 12 on the left side will pull the transmission plate 13 forward. When the transmission plate 13 moves forward, it will push the pull rod 12 on the right side. The movement of the pull rod 12 on the right side will push the cross plate 16 to move right. When the cross plate 16 moves, it will drive the card block 18 on the right side to move horizontally. At this time, the two card blocks 18 move to the side away from each other and break contact with the card slots, so that the adjusting rods 8 are unlocked.

[0033] As a preferred solution of the utility model, the tops of the two fixed frames 7 are fixedly connected with support frames 15, and the rear sides of the two support frames 15 are slidably connected to the front sides of the corresponding cross plates 16. The support frames 15 are used to conveniently limit the cross plates 16 so that the cross plates 16 can move laterally stably.

[0034] As a preferred solution of the utility model, the rear sides of the two support frames 15 are fixedly connected with return springs 14, and the rear sides of the two return springs 14 are rotatably connected to the front sides of the corresponding transmission plates 13. Through the elastic force of the return springs 14, the transmission plates 13 can be easily pushed backward and reset.

[0035] As a preferred solution of the utility model, the top of the fixed frame 7 is fixedly connected to a limiting frame 11, and the number of the limiting frames 11 is two.

[0036] As a preferred solution of the utility model, the right sides of the two horizontal plates 16 are fixedly connected with force storage springs 17, and the right sides of the two force storage springs 17 are fixedly connected to the corresponding support frames 15. The elastic force of the force storage springs 17 can conveniently push the horizontal plates 16 to move horizontally and reset.

[0037] The working principle of the utility model: in actual use, when it is necessary to weld the pressure vessel, the two semi-finished pressure vessels are respectively placed on the top of the two support plates 2, and a slot is opened at the position corresponding to the adjusting rod 8 according to the size of the pressure vessel to be fixed. At this time, the unlocking plate 10 is pushed to move horizontally. When the unlocking plate 10 moves horizontally, the card block 18 on the left side will be driven to move horizontally. At the same time, the movement of the unlocking plate 10 will pull the pull rod 12 on the left side, and the movement of the pull rod 12 on the left side will pull the transmission plate 13 forward. When the transmission plate 13 moves forward, the return spring 14 will be compressed and the pull rod 12 on the right side will be pushed. The movement of the pull rod 12 on the right side will push the cross plate 16 to move right. When the cross plate 16 moves, the force storage spring 17 will be compressed. At the same time, the movement of the cross plate 16 will drive the card block 18 on the right side to move horizontally. At this time, the two card blocks 18 move to the side away from each other and disengage from the card slot to unlock the adjusting rod 8. At this time, the adjusting rod 8 is pushed downward to drive the adjusting plate 9 to move downward. When the lever 12 is in motion, the upper support roller 6 is driven to move downward to fix the pressure vessel. At this time, the unlocking plate 10 is released, and the return spring 14 pushes the transmission plate 13 to move backward. When the transmission plate 13 moves, the pull rod 12 is pulled. At this time, the movement of the pull rod 12 on the left side will drive the unlocking plate 10 to move right and reset. At the same time, the storage spring 17 loses its restriction and pushes the cross plate 16 to move left and reset. At this time, the two clamping blocks 18 move to the side close to each other and engage with the clamping groove to fix the adjusting rod 8. By fixing the adjusting plate 9, the upper support roller 6 is kept fixed, and the pressure vessel is restricted by the cooperation of the support roller 6. At this time, rotating the threaded rod 5 can drive the threaded plate 4 to move horizontally. The movement of the threaded plate 4 can drive the slider 3 to move, thereby driving the right support plate 2 and the pressure vessel to move, so that the two pressure vessels are aligned. At this time, the pressure vessel can be welded. When the welding is completed, the pressure vessel is pushed to rotate, and the support roller 6 supports and assists the rotation of the pressure vessel, thereby completing the effect of welding the pressure vessel.
