A round block 407 is fixed at the end, and a spring 408 is sleeved on the guide rod 406 between the round block 407 and the fixed block B405. The two ends of the spring 408 are respectively fixedly connected to the round block 407 and the fixed block B405. The elastic coefficient of the spring 408 is selected and used by the technical personnel in this profession according to the actual situation; wherein, the open ends of the half-circuit A402 and the half-circuit B403 are abutted and matched, and the half-circuit A402 and the half-circuit B403 are connected to form a whole ring to clamp the flushing pipe into position.

[0035] The utility model has the advantage of clamping a flushing pipe by arranging a connecting block 401, a half clamping ring A402, a half clamping ring B403, a fixing block A404, a fixing block B405, a guide rod 406, a round block 407 and a spring 408, so as to clamp the flushing pipe in place, thereby keeping the flushing pipe stable and not easily shaking greatly due to vibration during the processing. This solves the problem that the flushing pipe will shake due to vibration during the processing, causing the discharged coolant to fluctuate and partially unable to be directly flushed at the processing location.

[0036] Specifically, a U-shaped frame 409 is fixedly provided at the outer end of the semi-circular retaining ring B403, and the U-shaped frame 409 can be used as a handle to facilitate pulling the semi-circular retaining ring B403.

[0037] Furthermore, the spring 408 is always in a compressed state, and the compressed spring 408 generates a thrust in the direction of the half-circlip A402, so that the open end of the half-circlip B403 butts against the open end of the half-circlip A402.

[0038] Furthermore, an extension block A5 is fixedly provided on the outer side of the bottom of the connecting rod 2, and an extension block B6 is fixedly provided on the outer side of the top of the movable rod 3.

[0042] Working principle: When using the device of the utility model, according to the actual processing situation, the handle 8 is rotated, the threaded rod 7 is rotated and moves longitudinally relative to the extension block A5, thereby pushing the extension block B6 to move longitudinally, so that the movable rod 3 moves longitudinally to adjust the height. Pull the U-shaped frame 409 obliquely downward, so that the semi-circular B403 moves accordingly, the fixed block B405 moves along the guide rod 406, the spring 408 is further compressed, the distance between the semi-circular A402 and the semi-circular B403 is increased, and the flushing pipe passes between the semi-circular A402 and the semi-circular B403, and then the U-shaped frame 409 is released. Under the action of the spring 408, the fixed block B405 moves back along the guide rod 406, and the semi-circular B403 moves accordingly, until the open end of the semi-circular B403 contacts the open end of the semi-circular A402, and the semi-circular A402 and the semi-circular B403 clamp the flushing pipe in place. When flushing during processing, the flushing pipe remains stable and is not easily shaken significantly due to vibration during processing.
