Abstract
The utility model discloses a combined device of convex keys on a main shaft of a charging gun drill. The combined device comprises a gun drill body, wherein the gun drill body comprises a motor, a gear case, a wire, a switch and a battery pack. The combined device is characterized in that the convex keys arranged on the main shaft of the gun drill are made in a combined manner. The combined device meets the operation requirement of frequent assembly and disassembly and exchange when the gun drill main shaft and a drill are combined, and has the advantages of convenience in operation and reasonable structure.
Description
Technical field
The armed brill of syndeton, especially multifunctional hand that the utility model relates to a kind of hand-held drill gun and drill chuck needs the anterior syndeton of drill gun easy to loading and unloading.
Background technology
The anterior main shaft of existing hand-held drill gun all is to be fixedly connected on transferring power on the drill gun main shaft by screw with being connected of drill chuck; But screw connects the normal particular requirement of loading and unloading that needs is felt inconvenient, time-consuming, take the labour; The application of the multiple drilling tool annex of the present multi-functional drill gun of incompatibility, transposing.
Summary of the invention
In order to overcome the weak point that the anterior main shaft of existing hand-held drill gun is connected with drill chuck with screw, the utility model provides a kind of combination production program that need not with the drill gun main shaft of the connection of the drill gun main shaft of screw connection.
The utility model solves the technical scheme that its technical problem adopted: comprise that the drill gun main body includes motor, gear-box, lead, switch, power brick; It is characterized in that on the drill gun main shaft, radially being shaped on through hole, insert the protruding key of making in the through hole then, and two ends are exposed uniformly on external diameter; Fix with pin again; The protruding key that combination is made on the drill gun main shaft is used for stirring drill chuck and rotates, and also is shaped on groove on the drill gun main shaft, and groove can be chimeric by the steel ball on the hole wall in the drill chuck.
The utility model is owing to adopt the Embedded production program of protruding key, and technology is simple, and cost is low; On main shaft, be shaped on protruding key and take up space for a short time, be fit to the little characteristics and the installation in space of this structure, connects all unaffectedly, solved the drill gun main shaft and be connected with drill chuck and load and unload the operation requirement of changing often, the utility model is easy to operate, and is rational in infrastructure.
