The gear rings 61 are meshed with the clamping block 51. The surfaces of the first clamping tube 1 and the second clamping tube 2 are fixedly connected with a support frame 62, and the support frame 62 is used in conjunction with the gear rings 61.

[0025] As a technical optimization solution of the utility model, the clamping block 51 can be transmitted through the setting of the limit assembly 6, and the ring gear 61 can be rotated to drive the clamping block 51 to rotate, which is convenient for clamping the pipeline and effectively improves the convenience of the clamping block 51.
