The support wheel 6 and the contact wheel 20 slide downwardly, and the surfaces of the eight support frames 4 are fixedly installed with mounting frames 16. The cross-section of the mounting frame 16 is "L"-shaped. With the help of the mounting frame 16, the support frame 4 can be slid downward. The surface of the fixed frame 8 is fixedly installed with four connecting plates 9. The internal sliding insertion of the connecting plate 9 is provided with a reinforcing rod 10. The surface of the reinforcing rod 10 is fixedly installed with a limit plate 11. The reinforcing rod 10 is inserted into the ground with the help of the limit plate 11, which can increase the stability of the clamping mechanism. Two protective ropes 12 are fixedly installed on the upper surfaces of the four connecting plates 9. The end of the protective rope 12 away from the connecting plate 9 is in contact with the limit plate 11. Fixed connection, the protective rope 12 can prevent the reinforcement rod 10 from sliding upward out of the interior of the connecting plate 9, and four contact pads 13 are fixedly installed on the surface of the fixed frame 8. The contact pad 13 is an elastic pad. The surface of the contact pad 13 is slidably connected to the reinforcement rod 10. The contact pad 13 can use elastic force to squeeze the reinforcement rod 10, so that the reinforcement rod 10 and the connecting rod are fixed. The surfaces of the eight moving frames 5 are fixedly installed with rubber pads 17, and the surface of the rubber pads 17 is in contact with the bolts 18. The rubber pads 17 can assist the staff in sliding the moving frame 5, and at the same time, the rubber pads 17 can increase the friction between the bolts 18 and the moving frame 5.

[0029] Working principle: when the valve body sleeve needs to be processed, first place the fixing frame 8 on the ground, then insert the reinforcement rod 10 into the ground with the help of the limit plate 11, then place the sleeve on the four rubber sleeves 2 in the middle, then slide the four rubber pads 17 on the outside, and the rubber pads 17 will drive the moving frame 5 to slide while sliding. After the moving frame 5 slides to the desired position with the assistance of the support wheel 6 and the contact wheel 20, stop sliding the rubber pad 17, and then rotate the four outer pins 22. The pins 22 move toward the direction close to the guide rod 7 with the help of the thread. When the latch 22 moves a certain distance, the surface of the latch 22 squeezes the guide rod 7. At this time, the guide rod 7 and the movable frame 5 are fixed, and then the four outer mounting brackets 16 slide downward. When the mounting bracket 16 slides downward, it drives the support bracket 4 to slide. When the support bracket 4 slides, it drives the support tube 3 to slide. When the support tube 3 slides, it drives the rubber sleeve 2 to slide. When the surface of the rubber sleeve 2 contacts the sleeve body 1, the sliding mounting bracket 16 is stopped, and then the bolt 18 is turned. The bolt 18 moves toward the direction close to the support bracket 4 with the help of the thread. When the bolt 18 moves a certain distance, the surface of the bolt 18 squeezes the rubber pad 17 on the movable frame 5. At this time, the support frame 4 and the movable frame 5 are fixed. Then, the four outer support cylinders 3 are slid, and the support cylinder 3 slides in the direction close to the sleeve body 1. While the support cylinder 3 slides, the auxiliary plate 14 is driven to slide. When the surface of the auxiliary plate 14 abuts against the sleeve body 1, the sliding support cylinder 3 is stopped. Then, the latch 15 is rotated, and the latch 15 moves in the direction close to the support frame 4 by means of the thread. After the latch 15 moves a certain distance, the surface of the latch 15 squeezes the support frame 4. At this time, the support cylinder 3 and the support frame 4 are fixed, and the sleeve body 1 is also limited on the eight rubber sleeves 2. At this time, the valve body sleeve can be processed. The effect achieved by the cooperation of the above components is: when the valve body sleeve is processed by clamping processing, the valve body sleeve can be fixed, and the valve body sleeve can be offset as much as possible, which is convenient for the staff to process the valve body sleeve and allows the staff to focus more on the implementation of the processing technology without worrying about the position change of the sleeve all the time, thereby improving the processing accuracy and efficiency.
