Description

Electric wrench comprehensive auxiliary tool connection parts

technical field

The utility model relates to an electric wrench accessory, in particular to a connection part of an electric wrench comprehensive auxiliary tool.

Background technique

An electric wrench is a kind of electric tool. The electric wrench is a wrench powered by electricity. The electric wrench has a host, and the host of the electric wrench is in the shape of a pistol. There is a motor on the main body of the electric wrench, and a switch is arranged on the handle of the main body of the electric wrench. In order to tighten or loosen the nut, the electric wrench host needs to be used together with auxiliary tools. The auxiliary tool of the electric wrench host is a set of socket wrenches of various specifications. The socket wrench has a cylindrical sleeve, and one end of the sleeve has a The hexagonal prism inner hole matched with the hexagonal nut, and the other end of the sleeve has a quadrangular prism inner hole matched with the quadrangular prism power output end of the main engine of the electric wrench. When in use, the inner hole of the square prism surface of the socket wrench is set on the square prism power output end of the electric wrench host, the inner hole of the hexagonal prism surface of the sleeve wrench is set on the hexagonal nut, start the main engine of the electric wrench, tighten or screw Loose nut.

The main engine of the electric wrench can output the rotating power. The above-mentioned electric wrench main engine with the quadrangular prism-shaped rotating power output end can only be used for tightening or loosening nuts in cooperation with the socket wrench. In actual use, it is sometimes necessary to tighten or loosen screws, drill holes or tap threads on equipment, and these operations also require rotational power. When tightening or unscrewing screws, drilling, tapping and other operations, multiple auxiliary tools such as screwdrivers, drill bits, and taps are needed, and these auxiliary tools are straight rod-shaped. When in use, straight rod-shaped auxiliary tools such as screwdrivers, drill bits, and taps need to be clamped on the rotary power output end of the front end of the electric tool. There is an internal thread hole opposite to the external thread in the thread head, and a drill bit holder is connected on the external thread head. One end of the drill clamp has an internal thread hole that matches the external thread head of the output end of the electric tool, and one end of the drill clamp has an adjustable three-jaw clamping hole, which can hold straight rods such as screwdrivers, drills, and taps. shape aids.

The rotary power output end of the above-mentioned electric wrench main engine is a square prism, which can only be connected with a socket wrench for tightening or loosening the nut.

In the prior art, there is no electric wrench integrated auxiliary tool connection component that enables the quadrangular prism-shaped rotary power output end of the electric wrench host to be connected to the straight rod-shaped auxiliary tool.

Contents of the invention

The purpose of this utility model is in order to overcome above-mentioned shortcoming, proposes a kind of electric wrench comprehensive auxiliary tool connection part that can be connected with straight rod-shaped auxiliary tool.

The utility model is realized by following method.

The invention scheme of the present utility model is: the connecting part of the electric wrench comprehensive auxiliary tool is a part that can connect the quadrangular prism-shaped rotating power output end of the electric wrench host to the drill bit holder, that is, one end of the electric wrench comprehensive auxiliary tool connecting part can be connected to the electric wrench The quadrangular prism rotating power output end of the main engine is connected, and the other end of the electric wrench comprehensive auxiliary tool connecting part can be connected with the drill bit holder.

In order to realize the above-mentioned invention scheme, the connecting part of the comprehensive auxiliary tool of the electric wrench has a cylindrical connector, one end of the connector has a quadrangular prism inner hole matched with the quadrangular prism-shaped rotating power output end of the electric wrench host, and the other end of the connector has a The external thread head matched with the internal thread hole at one end of the drill holder, the external thread head has an internal thread hole opposite to the external thread, the axis of the quadrangular prism internal hole, the external thread head, the internal thread hole and the axis of the connector On the same straight line, a screw rod is rotated in the internally threaded hole.

When installing, insert the quadrangular prism-shaped rotary power output end of the main unit of the electric wrench into the quadrangular prism inner hole at one end of the utility model, connect the main unit of the electric wrench with the utility model, and then screw the external thread head of the utility model into the drill bit holder In the internally threaded hole at one end, screw the screw rod into the internally threaded hole in the externally threaded head, then the drill bit holder is firmly connected to the rotary power output end of the electric wrench and a set of socket wrenches of various specifications.

When in use, clamp the straight rod-shaped auxiliary tools such as screwdrivers, drill bits, and taps in the adjustable three-claw clamping hole of the drill bit clamp, and use the electric wrench host to drive the utility model to rotate, and the rotation of the utility model can drive the drill bit clamp to rotate, and the drill bit The clamp rotates to drive screwdrivers, drills, taps and other straight rod-shaped auxiliary tools to rotate, so as to realize operations such as tightening or loosening screws, drilling or tapping on equipment.

The utility model can connect the electric wrench with straight rod-shaped auxiliary tools such as screwdrivers, drill bits, taps, etc. by connecting the drill bit clip, so that the main engine of the electric wrench can not only tighten or loosen the nuts, but also tighten or loosen the screws. For operations such as drilling or tapping on the equipment, one electric tool can be connected to a variety of auxiliary tools, reducing the amount of tools and reducing operating costs.

Below in conjunction with accompanying drawing, the utility model is described further.
