Traditional clamping methods, such as using pressure plates, are not only complex to operate but also difficult to maneuver flexibly in confined spaces, resulting in long operation times and low efficiency. Furthermore, the need to operate multiple clamping devices individually and sequentially further increases the difficulty and time cost of the operation. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figures 1-5The present invention includes a main body 1, with six protruding blocks 2 distributed at equal angles around the outer circumference of the main body 1. A guide plate 3 is connected to the lower end of the main body 1, and an end seat 4 is connected to the lower end of the guide plate 3. A cavity 5 is opened inside the end seat 4, and a slider 6 is slidably arranged inside the cavity 5. A connecting rod 7 is connected to the middle of the upper end of the slider 6. The upper end of the connecting rod 7 extends through to the top of the main body 1. A driving plate 8 is sleeved on the upper part of the connecting rod 7. The driving plate 8 is movably embedded in the upper end of the protruding blocks 2, and six arc-shaped grooves 9 are distributed around the circumference of the surface of the driving plate 8. A cover plate 10 is provided on the upper end of the driving plate 8, and the cover plate 10 is connected to the protruding blocks 2 by bolts 11.

[0023] A handle 12 is fitted on the upper part of the connecting rod 7. The handle 12 is connected to the drive plate 8 by a screw 13. A locking nut 14 is threaded inside the handle 12 and located on the upper part of the connecting rod 7.

[0024] Each of the six protruding blocks 2 has a guide sleeve 15 embedded inside. A telescopic column 16 is movably installed inside the guide sleeve 15. A pin 17 is connected to one side of the upper end of the telescopic column 16. The upper end of the pin 17 extends through to the upper end of the protruding block 2. A moving groove 18 is opened in the protruding block 2 corresponding to the through point of the pin 17. The pin 17 is located in the moving groove 18, and the upper part of the pin 17 is located in the arc groove 9. A spring 19 is sleeved on the outer end of the telescopic column 16 between the pin 17 and the inner wall of the protruding block 2.

[0025] Handles 20 are symmetrically connected to the upper end of the cover plate 10;

[0026] The upper ends of the six protruding blocks 2 are provided with mounting grooves 21, and the drive plate 8 is located in the mounting grooves 21, which facilitates the rotation of the drive plate 8 within the mounting grooves 21.

[0027] The surface of the handle 12 is provided with anti-slip ridges 22 to increase friction.

[0028] Working principle: Initial state:

[0029] When no clamping operation is performed, the telescopic column 16 maintains a certain extension length under the action of the spring 19, and the pin 17 is located in the moving groove 18 and is at the starting position of the arc groove 9 of the drive plate 8.

[0030] The drive plate 8 is limited in the mounting groove 21 on the protrusion 2 by the cover plate 10, while the connecting rod 7 passes through the main body 1 and connects to the slider 6. The slider 6 is in a free state in the cavity 5.

[0031] Operation process:

[0032] Hold the handle 20 and rotate the handle 12. The handle 12 is connected to the drive plate 8 by the screw 13. Therefore, rotating the handle 12 will drive the drive plate 8 to rotate. When the drive plate 8 rotates, the arc groove 9 on it will guide the pin 17 to move. Since the pin 17 is connected to the telescopic column 16, the movement of the pin 17 will drive the telescopic column 16 to extend and retract within the guide sleeve 15.

[0033] The telescopic movement of the telescopic column 16 changes its extension length, thereby achieving the clamping of the annular part. The spring 19 plays a role in providing clamping force and maintaining the stability of the telescopic column 16 during this process.

[0034] Compacted state:

[0035] When the handle 12 is rotated to the desired position, the arc groove 9 on the drive plate 8 will guide the pin 17 to the clamping position, at which time the telescopic column 16 extends and clamps the ring-shaped part.

[0036] The locking nut 14 can be used to lock the handle 12, thereby locking the drive plate 8 and keeping the telescopic column 16 pressing the parts stably.

[0037] Released state:

[0038] When the clamping force needs to be released, loosen the locking nut 14, rotate the handle 12 in the opposite direction, the drive plate 8 will rotate in the opposite direction, the arc groove 9 guides the pin 17 back to the starting position, and the telescopic column 16 retracts, thereby releasing the clamping force on the annular part.

[0039] In summary, the telescopic linkage clamping mechanism drives the drive plate 8 to rotate via the handle 12, and the linkage telescopic column 16 and pin 17 move within the arc groove 9 to achieve uniform clamping of the annular part. The mechanism is compact, easy to operate, and highly efficient, and is particularly suitable for clamping operations in confined spaces.
