[0008] Preferably, the clamping mechanism comprises: a movable rod, one end of the movable rod is screwed into the end of the long frame; a rotating frame, the middle of the rotating frame is fixedly arranged at the other end of the movable rod; a limiting disc and an eccentric disc, the limiting disc and the eccentric disc are movably sleeved on the movable rod; a clamping ring, the clamping ring is integrally formed and arranged on the periphery of the eccentric disc; a plurality of inclined blocks, the inclined blocks are respectively fixedly arranged on the two sides of the eccentric disc; a bolt hole, the bolt hole is open in the limiting disc; a plurality of bolt plates, the bolt plates are fixedly penetrated in the bolt hole of the limiting disc; a threaded bolt, the threaded bolt is movably penetrated and arranged in the middle of the limiting disc and the eccentric disc; and a middle frame, the end of the middle frame is sleeved on the end of the threaded bolt.
[0009] Preferably, the eccentric disc and the two limiting discs are located in the middle of the middle frame and the long frame, the inner walls of the middle frame, the short frame and the long frame are fixedly provided with two reinforcing plates, the lengths of the reinforcing plates are different, and the inclined blocks are arranged on the sides of the plurality of bolt plates.
[0010] Preferably, the movable rod is matched with the piston hole of the movable sleeve, the shape of the sliding frame is matched with the fixed hole, and the threaded rod is screwed and penetrated in the end of the movable rod through the threaded hole.
[0011] Preferably, the inner wall of the penetration hole is open and provided with a threaded groove, the threaded rod is screwed and penetrated in the middle of the sliding frame through the penetration hole, the sliding frame and the movable sleeve are perpendicular, the two ends of the sliding frame are matched with the sliding hole, and the sliding frame can move in the sliding hole of the movable sleeve.

[0013] Preferably, the middle hole is located in the middle of the rotating disc, the end of the threaded cylinder is fixedly arranged at the end of the long frame, the end of the short frame abuts against the rotating frame, the shapes of the short frame, the long frame, the rotating frame and the middle frame are consistent, and the threaded bolt is deviated to one side of the center of the eccentric disc.
[0014] The beneficial effects of this invention are as follows: the rotating disk and two intermediate disks are arranged in a ring, so that the threaded columns on both sides of the rotating disk and the movable rods on both sides of the two intermediate disks are arranged in a ring. The threaded columns on both sides of the rotating disk have opposite thread helical directions. The two threaded columns rotate synchronously and move in the two threaded cylinders respectively, so that the two threaded cylinders move closer to each other, so that the long rib frames at the ends of the two threaded cylinders move closer to each other, so that the two movable sleeves move closer to each other, so that the two movable sleeves move along the movable rods, and the spacing between the three locking rings can be adjusted. The three locking rings can be inserted into the notches of various sizes of round lock nuts. The spacing between the three locking rings can be adapted to various sizes of round lock nuts. At the same time, the spacing between the force point of the eccentric disk and the round lock nut can be adjusted, and the spacing between the two force points of the eccentric disk can be adjusted, so that the three locking rings can withstand greater forces without deformation. The three locking rings can complete the disassembly and installation of various sizes of round lock nuts. The eccentric disc and the locking ring rotate around the axis of the movable rod. When the eccentric disc and the locking ring rotate, they are biased to one side of their center. When the eccentric disc and the locking ring rotate, the edge position of the locking ring changes. The locking ring can be matched with round lock nuts of various sizes. At the same time, the distance between the edge of the locking ring and the axis of the movable rod changes, and the position of the force on the eccentric disc changes. This allows the eccentric disc to be matched with round lock nuts of various locking forces, and to complete the disassembly of round lock nuts of various locking forces. The pin is inserted at the intersection of the spiral opening and the intermediate opening. The pin is inserted into the spiral opening of the threaded cylinder and the intermediate opening of the threaded column. When the threaded column is loosened, its rotation direction is opposite to the spiral direction of the spiral opening. The pin moves in the opposite direction to the spiral direction of the spiral opening. When the threaded column is rotated, the pin is horizontal in the spiral opening. The pin is locked at the intersection of the spiral opening and the intermediate opening, so that the threaded column cannot rotate in the middle of the threaded cylinder. The threaded column is fixed in the threaded cylinder and cannot move, thus ensuring that the positions of the two threaded cylinders and the two long rib frames are fixed. Since multiple movable rods move synchronously in the movable sleeve, the positions of multiple movable rods and the movable sleeve are fixed. The positions of the three locking rings can be quickly and firmly positioned, which can ensure that the three locking rings are accurately locked in the notch of the round lock nut, and has the advantage of firmly fixing the round lock nut.

The two limiting discs 42 are located on both sides of the eccentric disc 43, and the center of the limiting disc 42 is offset to one side of the center of the eccentric disc 43.
[0025] In this invention, a locking ring 44 is integrally formed and disposed around the eccentric disk 43.

The inner walls of the central prism frame 49, the short prism frame 17 and the long prism frame 18 are each fixedly provided with two reinforcing plates 19. The lengths of the multiple reinforcing plates 19 are different. The multiple reinforcing plates 19 reinforce the inner walls of the central prism frame 49, the short prism frame 17 and the long prism frame 18, which can increase the load-bearing capacity of the central prism frame 49, the short prism frame 17 and the long prism frame 18. The inclined block 45 surrounds the sides of the multiple pin plates 46.
[0027] In this invention, the movable rod 21 is matched with the piston port 23 of the movable sleeve 2, the shape of the sliding frame 26 is matched with the fixed port 24, the threaded rod 28 is threaded through the threaded hole 25 at the end of the movable rod 21, the inner wall of the through port 27 is provided with a threaded groove, the threaded rod 28 is threaded through the through port 27 in the middle of the sliding frame 26, the sliding frame 26 and the movable sleeve 2 are kept perpendicular, the two ends of the sliding frame 26 are matched with the sliding port 29, and the sliding frame 26 can move in the sliding port 29 of the movable sleeve 2.
[0028] In this invention, the two threaded posts 34 on both sides of the rotating disk 35 have opposite helical directions, and the helical direction of the helical opening 37 is opposite to that of the threaded post 34. The threaded post 34 can rotate and move in the middle of the threaded cylinder 3. The helical opening 37 and the middle opening 36 coincide, so that the pin rod 32 is inserted into the helical opening 37 and the middle opening 36. The pin rod 32 locks the threaded post 34 in the middle of the threaded cylinder 3, preventing the threaded post 34 from rotating in the middle of the threaded cylinder 3, and fixing the threaded post 34 in the middle of the threaded cylinder 3. The helical direction of the helical opening 37 is consistent with the helical direction of the corner strip 31, and the rolling ring 33 is located in the middle of the two corner strips 31.
[0029] In this invention, the middle opening 36 is located in the middle of the rotating disk 35, the end of the threaded cylinder 3 is fixedly set at the end of the long prism frame 18, the end of the short prism frame 17 abuts against the rotating frame 4, the short prism frame 17, the long prism frame 18, the rotating frame 4 and the middle prism frame 49 have the same shape, and the threaded bolt 48 passes through the eccentric disk 43 at a position biased towards one side of its center.
[0030] In use, first, hold the lever 1 with one hand and move the corner plate 16 so that the end of the short prism 17 abuts against the rotating frame 4. The two threaded posts 34 are aligned with the middle of the two threaded cylinders 3 respectively, and the three locking rings 44 are located in the three notches of the round lock nut respectively. Then, keep the two threaded posts 34 and the two threaded cylinders 3 parallel, and use the other hand to rotate the disk 35 and the two threaded posts 34. The two threaded posts 34 rotate in the middle of the two threaded cylinders 3, so that the two threaded posts 34 move simultaneously in the middle of the two threaded cylinders 3. The threaded posts 34 enter the middle of the threaded cylinders 3, so that the two threaded cylinders 3 are close to each other, and at the same time, the two long prisms 18 are pulled together, so that the movable rod 21 moves in the middle of the movable sleeve 2. The two movable rods 21 and the rotating disk 35 quickly move closer together along their center point as shown in the attached instruction manual. Figure 3 As shown, the three locking rings 44 move towards the center simultaneously and are engaged in the notch of the round lock nut. Then, the pin 32 is inserted into the spiral opening 37 of the threaded cylinder 3, and the end of the pin 32 is aligned with the middle opening 36 so that the pin 32 is inserted into the middle opening 36 of the threaded column 34. Since the spiral direction of the spiral opening 37 is opposite to the spiral direction of the thread on the surface of the threaded column 34, the pin 32 locks the threaded column 34 to prevent the threaded column 34 from rotating in the middle of the threaded cylinder 3, so that the threaded column 34 is fixed in the middle of the threaded cylinder 3. Then, the actuating rod 1 is pushed at the same time, and the three locking rings 44 are engaged in the notch of the round lock nut, thereby driving the round lock nut to rotate and completing the disassembly or installation of the round lock nut. During adjustment, the eccentric disk 43 and the locking ring 44 can be rotated. The eccentric disk 43 and the locking ring 44 rotate around the axis of the movable rod 41. Since the axis of the movable rod 41 is biased towards one side of the center of the eccentric disk 43 and the locking ring 44, the bias of the eccentric disk 43 and the locking ring 44 towards one side of the axis of the movable rod 41 can be adjusted, thereby adjusting the distance between the three locking rings 44 so that the three locking rings 44 can be matched with various sizes of round lock nuts. At the same time, the central frame 49 abuts against the eccentric disk 43 at different positions. The position of the central frame 49 abutting against the eccentric disk 43 can be adjusted, thereby adjusting the support position of the central frame 49 on the eccentric disk 43. According to the lever principle, the force capacity of the locking ring 44 can be adjusted so that the three locking rings 44 can be matched with the disassembly work of various tight and loose round lock nuts.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
