Abstract
The utility model discloses a chuck wrench comprising a handle and a wrench bar. The handle is shaped in a tetragonal prism and is wrapped by a rubber sleeve. The rubber sleeve is circular in outline and provided with antislip lines. A sleeve is fixedly sleeved on the wrench bar, a spring is fixedly connected below the sleeve and sleeved to the wrench bar and a hollow spacer is fixedly connected below the spring. The wrench bar extends out of the spacer. The chuck wrench is simple in structure, accuracy in chuck adjustment of operators can be increased, accidents caused when the operators forget to pull out the chuck wrench from a chuck can be avoided, and the chuck wrench is safe and reliable.
Description
Technical field
The utility model relates to the lathe instrument, relates in particular to chuck handle.
Background technology
Chuck handle is all-metal in the prior art, when needs are accurately operated, and the difficult control of operator, in addition, the operator forgets chuck handle on chuck after having adjusted chuck easily, in case start the machine, be thrown out of at action of centrifugal force lower chuck spanner, have potential safety hazard.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, and a kind of accurate operation, safe and reliable chuck handle of being beneficial to is provided.
The technical solution of the utility model is: a kind of chuck handle, comprise handle and wrenching bar, described handle is cubic cylinder, handle coats rubber sleeve outward, described rubber sleeve outline is for circle and be provided with anti-skidding line, and fixed cover is equipped with sleeve on the wrenching bar, the fixedly connected spring in described sleeve below, spring housing place on the wrenching bar and below the pad of fixedly connected hollow, described wrenching bar stretches out from pad.
The beneficial effects of the utility model are: because handle has coated anti-skidding rubber sleeve outward, being more conducive to the operator accurately operates, after finishing using, under the effect of spring force, wrenching bar is withdrawn behind the pad automatically, whole chuck handle comes off from chuck, can not forget under the situation of extracting chuck handle the operator to have an accident, and is safe and reliable.
