Abstract

The utility model discloses a head-replaceable internal hexagonal wrench which comprises a wrench head 1, a connection body 5 and a handle 4. The connection body 5 is formed by connecting two connection pieces in detachable mode. One connection piece is an inner square round sleeve piece and is provided with a limit hole, and the other connection piece is provided with an elastic protruding head matched with the limit hole. The elastic protruding head matched with the limit hole of the connection body 5 is arranged at one end of the wrench head 1, and one end of the handle 4 is fixedly connected with the connection body 5 through a ratchet wheel mechanism. The wrench has the largest advantages that the wrench head 1 can be replaced, wrench heads in different types can share one wrench handle 4, operation can be conducted again by simple replacing the wrench head in the identical type after the wrench head 1 loses efficacy, the wrench handle 4 and the connection body 5 can be used in long term, and the wrench saves resources and improves resource utilization rate.

Description

Interchangeable head hex wrench

technical field

The utility model relates to a wrench, in particular to a replaceable head type inner hexagonal wrench. the

Background technique

As we all know, the hexagonal wrench is one of the commonly used tools in the machinery industry. The traditional hexagonal wrench is generally composed of multiple models. The handle and the wrench head are forged together. Hexagonal screws, over time, will become invalid as the wrench head works for a long time, so that the more commonly used types of wrenches will become invalid, and a complete set of wrenches must be purchased again, resulting in waste of resources, poor sustainability, and low overall work efficiency. the

Contents of the invention

The purpose of the utility model is to overcome the disadvantages of the background technology and provide a replaceable head type inner hexagonal wrench, which can save resources, improve resource utilization, and improve overall work efficiency. the

In order to achieve the above object, the utility model adopts the following technical solutions:

The replaceable head type inner hexagonal wrench includes a handle, a connecting body and a wrench head.

The handle has the following characteristics: the shape of the handle is L-shaped, and one end of the handle is provided with a ratchet mechanism.

The connecting body has the following characteristics: the connecting body is formed by detachable connection of two connecting pieces, one is a square-inner circular kit, and one end of the other connecting piece is detachable with the square-inner round kit through a limiting hole. connection, the other end of which is fixedly connected with the ratchet mechanism of the handle; One end of a connecting piece is provided with an elastic protrusion matching the limiting hole of the inner square circular sleeve.

The wrench head has the following characteristics: one end of the non-direct working part of the wrench head is set in the inner square circular sleeve of the connecting body, and the other end is the direct working part of the hexagonal wrench head; the non-direct working part of the wrench head One end is detachably connected to one end of the connecting body through a limit hole, and the other end of the connecting body is fixedly connected to the ratchet mechanism at one end of the handle; one end of the non-direct working part of the wrench head is in the shape of a square, and is connected to the inner part of the connecting body. The detachable connection of the square cylinder set; the detachable connection between one end of the non-direct working part of the wrench head and the inner square cylinder set of the connecting body means that a limit hole is provided inside the inner square circular set, and the wrench One end of the non-direct working part of the head is provided with an elastic protruding head matched with the limiting hole of the inner square circular set.

When operating, connect the connecting body and the ratchet mechanism of the handle, and then, you only need to select the corresponding type of wrench head and the inner square kit of the connecting body to fix it through the limit hole. In the future use, in order to adapt For different types of hexagon socket screws, only the wrench head needs to be replaced. the

Due to the adoption of the above-mentioned technical solution, the utility model has the advantages that the replaceable head type Allen wrench described in the utility model can quickly replace the matching wrench head according to the different types of the Allen screw, which improves the work efficiency;

When the wrench fails for a long time, the handle can continue to be used, and it can be used normally only by replacing the failed wrench head, which saves resources and improves resource utilization;

The wrench is equipped with a ratchet mechanism, which greatly saves and reduces the labor time and labor intensity of the operator during work.

Fig. 2 is a combined state schematic diagram of the connector of the present invention;

Fig. 3 is a schematic diagram of the use state of the utility model;

Among them: 1, wrench head, 2 and 3, connector, 4, handle, 5, connector, 6, limit hole.

Detailed ways:

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

The utility model includes a wrench head 1, a connecting body 5, and a handle 4. The wrench head 1 is detachably connected with the connecting body 5 through a limit hole, and the connecting body 5 is fixedly connected with the handle 4 through a ratchet mechanism; It is formed by detachable connection with the connecting piece 3 through a limiting hole. the

When in use, since the connecting body 5 has been fixedly connected with the handle 4 through the ratchet mechanism, you only need to select the corresponding wrench head according to the type of the hexagon socket head screw, and then make it detachably connected with the connecting body 5 through the limit hole 6 to use . the
