Abstract
The utility model provides a pneumatic or electric power-output shaft of a wrench, which comprises a connector for passing the torque force; wherein the back end of the connector and the power-output shaft both have a conical section and a joint trough or a hole is arranged on the power-output shaft on the back the conical section, which is matched with a quick exchange connecting piece. The utility model can not only match with the wrench tool, but also be connected with a rill bit and a grip which adds boring function to the traditional pneumatic or electric wrench; therefore the utility model has the advantages that the device can save the equipment payout of the user, reduce the portage weight when used outside and facilitate the usage and operation by rapid assembly and disassembly of the drill bit and the grip.
Description
Technical field
The utility model relates to a kind of power output shaft that is applied on portable pneumatic machinery or the motor machine.
Background technology
Portable pneumatic machinery or motor machine are on the production line made of automobile, motorcycle or other electronic product, the assembly line or the common equipment during these product ordinary maintenances, such as, loading and unloading tire or other operation in automobile, motorcycle are made just need to use electric wrench or pneumatic impact spanner.Need use electric drill at these working environments and workplace toward contact.This situation also is present in family to be used, and in the family of having deep love for doing it yourself to finish, need be equipped with these different instruments simultaneously.Present pneumatic or electric wrench power output shaft can only match with spanner, can't match with drill chuck, and the user must not no longer be equipped with rig, has therefore increased a large amount of expense expenditures.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pneumatic or electric wrench power output shaft that can be connected with drill chuck.For this reason, the utility model by the following technical solutions: it comprises the connector that transmits torsion, and at the rear portion of described connector, described power output shaft has one section and is conical; At conical rear, described power output shaft is provided with link slot or the connecting hole that cooperates with quick-change coupling.Owing to adopt the technical solution of the utility model, the utility model is except can be with Wrench cooperates, can also link to each other with drill chuck, make traditional pneumatic or electric wrench have spanner and boring bar tool function concurrently, save user's installation cost expenditure, carried burden when having reduced user's out using.And the utility model can also be realized the fast assembling-disassembling with drill chuck, can greatly user-friendly and use.

The specific embodiment
With reference to accompanying drawing.The utility model 17 comprises the connector 171 that transmits torsion, and at the rear portion of described connector, described power output shaft has one section and is conical 175; At conical rear, described power output shaft is provided with link slot 172 or the connecting hole that cooperates with quick-change coupling.
In the present embodiment, described link slot 172 is a cannelure.Described connector 171 is the quartet connection head, the adjacent seamed edge arc surface transition of described quartet connection head, described arc surface 178 and described output shaft adaptive drill chuck endoporus suitable, like this, when described output shaft is connected with the drill chuck endoporus, can play the effect of further location, improve precision.
The front side wall of described link slot has can make power output shaft be subjected to the slope 176 of component forward when link slot cooperates with quick-change coupling, makes conical 175 can give full play to the centering mating reaction.
The side of described connector is provided with spring eye 177, the ball 174 that is provided with spring 173 in the described spring eye and is pushed to the aperture direction by spring.
The head of described connector is provided with threaded connection hole 179, the center line of described threaded connection hole and the central lines of power output shaft.
Connector of the present utility model can link to each other with spanner, transmits torsion.The utility model also can utilize the link slot 172 and the quick connector of drill chuck to realize fast assembling-disassembling, and utilizes taper shape 175 and arc surface 178 to strengthen precision, utilizes connector 171 to transmit torsion.Accompanying drawing 3,4,5 and 6 has shown present embodiment and hand fastening drill clutch 10 respectively, has had the connection status of the hand fastening drill clutch 40 of the hand fastening drill clutch 20 of auto-lock function, spanner drill chuck 30, strap wrenches function.
