Legend description:

1. a chassis; 2. a slide block; 3. clamping blocks; 4. an external threaded hole; 5. an internal threaded hole; 6. a first hidden groove; 7. a first perforation; 8. a second hidden groove; 9. and a second perforation.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples:

referring to fig. 1-2, the utility model provides a chuck for a lathe, which comprises a chassis 1, wherein a sliding groove is formed on the chassis 1 around an axis, a sliding block 2 is slidably arranged at the position of the sliding groove, a clamping block 3 is movably arranged on the sliding block 2 through a rotating shaft, the clamping block 3 is in a ladder-shaped structure, an external threaded hole 4 and an internal threaded hole 5 are respectively formed at two ends of the sliding block 2, a first hidden groove 6 is formed at the highest position of the clamping block 3, a first through hole 7 communicated with the external threaded hole 4 and the internal threaded hole 5 is formed at the position of the first hidden groove 6, a second hidden groove 8 is formed at the lowest position of the first hidden groove 6, a second through hole 9 communicated with the external threaded hole 4 and the internal threaded hole 5 is formed at the position of the second hidden groove 8, bolts are arranged at the positions of the first through hole 7 and the second through hole 9, and the bolts are screwed on the external threaded hole 4 or the internal threaded hole 5.
