Abstract

The invention relates to a drill chuck capable of preventing disengagement of a wrench. The drill chuck capable of preventing disengagement of the wrench comprises a drill body, a clamping jaw, a wrench hole and a drill body gear ring portion, wherein the drill body is connected on a spindle, the clamping jaw is mounted inside the drill body, extends out of the lower end of the drill body and is used for mounting and demounting a drill, the wrench hole for allowing insertion of a wrench inserting portion of a wrench handle is formed on the outer wall of the drill body, and the drill body gear ring portion is meshed with a wrench gear ring portion of the wrench handle. A disengagement preventing component for preventing the wrench gear ring portion of the wrench handle to disengage from the drill body gear ring portion of the drill body is mounted at the lower end of the drill body. When the drill chuck rotates, the disengagement preventing component mounted on the drill body prevents the wrench from disengaging from the drill body and enables the drill to be mounted on the drill body firmly.

Description

[0001] technical field [0002] The present invention relates to drill chuck structures. [0003] Background technique [0004] The general electric drill is one of the many tools used when drilling holes in metal, wood and other substances. When using an electric drill, the corresponding drill bit must be installed on the drill bit holder in order to align the diameter of the perforated hole. [0005] Such as figure 1 As shown, the conventional drill chuck 10 consists of a drill body 11 connected to the main shaft, a drill gripper 13 installed inside the drill body 11 and protruding from the lower end of the drill body 11, and a wrench hole 14 arranged at the lower end of the drill body 11 , The drill body ring gear 12 arranged on the drill body 11 and the wrench handle 20 of the elastic drill bit, the insertion part 21, and the wrench ring gear 22 constitute. [0006] When the drill chuck 10 is loading and unloading the drill bit, the insertion part 21 of the wren...
