The side surface of the mounting rod 7 is provided with two mounting grooves 8 and a limiting groove 9. A top rod 10 is rotatably installed in the mounting groove 8. A rectangular cavity 11 is provided inside the mounting rod 7. A spring 12 is fixedly installed on the lower surface of the inner cavity of the rectangular cavity 11. A connecting block 13 is fixedly installed on the top of the spring 12. The cross-sectional shape of the connecting block 13 is the same as that of the rectangular cavity 11. The side surface of the connecting block 13 is in sliding contact with the inner surface of the rectangular cavity 11, so that the connecting block 13 can be moved in the rectangular cavity. 11 moves in the inner cavity, two pull rods 14 are rotatably installed on the surface of the connecting block 13 and penetrate into the installation groove 8, and a strip hole 23 connected to the rectangular cavity 11 is opened on the inner cavity surface of the installation groove 8. The pull rod 14 is located in the strip hole 23, which is convenient for the pull rod 14 to move in the installation groove 8. The end of the pull rod 14 away from the connecting block 13 is rotatably connected to the top rod 10. A vertical rod 15 that penetrates the top of the installation rod 7 is fixedly installed on the upper surface of the connecting block 13. A locking block 16 is rotatably installed on the top of the vertical rod 15. The side surface of the locking block 16 is provided with a vertical groove 17 and a locking block 16 that is connected to the vertical groove 17 The horizontal grooves 18 are connected, and a locking cylinder 19 is fixedly installed on the top of the mounting rod 7. A clamping block 20 is fixedly installed on the inner side surface of the locking cylinder 19. The outer shape of the locking block 16 is adapted to the inner shape of the locking cylinder 19. The clamping block 20 is adapted to the vertical groove 17 and the horizontal groove 18. A circular hole 21 is provided on the surface of the straightening wheel 3. Two limit blocks 22 are fixedly installed on the inner surface of the circular hole 21. The limit groove 9 is adapted to the limit block 22.

[0022] The working principle of the above embodiment is:

[0023] When in use, the straightening wheel 3 is sleeved on the surface of the mounting rod 7 through the circular hole 21, and the straightening wheel 3 is used to press the push rod 10 into the mounting groove 8. When the push rod 10 contracts into the mounting groove 8, the pull rod 14 is compressed into the rectangular cavity 11, so that the pull rod 14 pushes the connecting block 13 upward. At this time, the spring 12 is stretched until the push rod 10 is located above the straightening wheel 3. When the push rod 10 is separated from the straightening wheel 3, the spring 12 loses its restraint and retracts, pulling the connecting block 13 downward, and then can drive the pull rod 14 to move downward near one end of the connecting block 13, and the push rod 10 is ejected from the mounting groove 8 and connected to the straightening wheel 3 through the pull rod 14. The straightening wheel 3 is blocked by the micro hydraulic rod 5, and the supporting ring 6 is pushed up, so that the supporting ring 6 pushes the straightening wheel 3 upward, so that the straightening wheel 3 is clamped by the supporting ring 6 and the push rod 10, and at the same time, the limit block 22 is inserted into the limit groove 9 to prevent the straightening wheel 3 from rotating on the mounting rod 7, and then the locking block 16 is pressed downward so that the locking block 16 is inserted into the locking cylinder 19, and the block 20 is inserted into the vertical groove 17, and then the locking block 16 is rotated so that the block 20 in the vertical groove 17 is inserted into the horizontal groove 18, so that the locking block 16 can be fixed in the locking cylinder 19, and then the push rod 10 can be limited.

[0024] Embodiment 2, based on embodiment 1, a through hole 24 connected to the rectangular cavity 11 is opened on the top of the mounting rod 7, and the vertical rod 15 is located in the through hole 24. The outer surface of the vertical rod 15 is in sliding contact with the inner surface of the through hole 24, which facilitates the telescopic movement of the vertical rod 15 in the rectangular cavity 11.
