In order to realize the technical purpose, the technical proposal of the utility model is that:
the utility model provides a novel chuck, includes chuck body, with chuck body screwed connection's lock nut and kicking block, be equipped with on the chuck body and press from both sides the groove, press from both sides the sunken spacing groove that forms of groove bottom part, the kicking block is located the spacing inslot, and the kicking block is by lock nut drive up-and-down motion, and kicking block top surface is the cambered surface. The utility model discloses chuck simple structure can press from both sides the work piece firmly, and the kicking block circular arc is in the face of cylindrically realizing comprehensive parcel by the centre gripping thing when pressing from both sides tightly, is the face contact when pressing from both sides tightly, and the reliability is high, is difficult for taking place wearing and tearing by the workpiece surface of this chuck centre gripping, and the locking nut on this chuck can not appear dropping the condition of losing.
Preferably, the top of the top block is coated with a wear-resistant layer. This arrangement can further prevent the surface of the clamped workpiece from being worn.
As a further preferable scheme, the wear-resistant layer is sponge rubber.
As preferred scheme, be equipped with the vertical step shape through-hole that runs through on the kicking block, step shape through-hole includes macropore and aperture from last to down in proper order, the lock nut top is equipped with the spliced pole, and the spliced pole is located step shape through-hole, and the spliced pole top sets firmly the gasket that the level set up, and the gasket is located the macropore, and the diameter of gasket is less than the macropore internal diameter and is greater than the aperture internal diameter.
As a further preferable scheme, the gasket is fixed on the top of the connecting column through a limiting nut.
Preferably, a threaded hole is formed in the top of the chuck body. The arrangement can ensure that the chuck is in threaded connection with the screw rod on the bracket, and the chuck is convenient to mount and dismount on the bracket.
