Description

A kind of auxiliary thread taking device

technical field

The utility model relates to an auxiliary wire-taking pulley device, which belongs to the technical field of special machinery tools.

Background technique

When the hexagonal head of the bolt is broken and only the threaded part remains, it is often difficult to remove the remaining thread due to the limited force applied, especially the rusted thread. When the general wire extractor is taking the wire, the wire opening is often screwed in. During the wire withdrawal process, because the wire is not fixed and the friction is not enough, the broken wire cannot be taken out.

If the threaded thread mouth is the nozzle of a faucet, it will be corroded, and it will be more difficult to take the silk; on the other hand, the silk extractor lacks a force torque, and it is difficult to take out the silk mouth with bare hands, making it difficult for the silk extractor to function.

In order to remove the remaining thread from the screw hole, a special tool must be designed to achieve it.

Contents of the invention

The purpose of the utility model is to solve the problem that the thread is difficult to take out due to the broken end of the existing screw, and the utility model provides an auxiliary screw thread pulling device.

The technical scheme of the utility model is as follows, a kind of auxiliary wire taking sleeve head device is made up of the hexagonal cap with conical head and small hexagonal bolt. The hexagonal cap with a conical head is a conical head structure at one end of the hexagonal cap plane, and the center of the hexagonal cap with a conical head is a round through hole; two corresponding sides on the hexagonal sides of the hexagonal cap are respectively provided with a screw hole The screw holes and the centerline are perpendicular to the centerline of the hexagonal cap with a conical head; the two screw holes are respectively equipped with small hexagonal bolts, and the two small hexagonal bolts are relatively straight to the centerline of the hexagonal cap.

The hexagonal cap is connected with the conical head as a whole and formed by machining at one time; it can also be formed by welding the hexagonal cap and the conical head.

The hexagonal cap and the small hexagonal bolt are made of alloy steel, and after heat treatment, they have a certain hardness and toughness; because the small hexagonal bolt needs to bear a relatively large shearing force when working.

The working principle of the utility model is as follows. In case of the situation that the broken end of the screw cannot be taken out, just insert the hexagonal cap with the conical head of the device of the utility model, align the two small hexagonal bolts with the broken screw, and then use a wrench to Tighten the hexagons of the two small hexagonal bolts separately, and let the two small hexagonal bolts move towards each other until they touch the broken head screw, and continue to tighten the small hexagonal bolts; after the two small hexagonal bolts are tightened, use a wrench to tighten The hexagonal cap of the small hexagonal bolt exerts force on the broken head screw, and the broken head screw is loosened until the broken head screw is taken out.

The beneficial effect of the utility model is that the device of the utility model is simple to manufacture and easy to use, and can solve the problem that the mouth for rusty thread is difficult to take.

Detailed ways

The specific embodiment of the utility model is as shown in Figure 1.

An auxiliary thread-taking sleeve device is composed of a hexagonal cap 1 with a conical head 3 and a small hexagonal bolt 2 . The hexagonal cap 1 with the conical head 3 is a conical head structure at one end of the hexagonal cap plane, and the center of the hexagonal cap with the conical head is a round through hole; two corresponding sides on the hexagonal sides of the hexagonal cap are each provided with a Screw hole; the screw hole and the centerline are perpendicular to the centerline of the hexagonal cap with conical head; two small hexagonal bolts 2 are respectively installed in the two screwholes, and the two small hexagonal bolts 2 are relatively straight to the centerline of the hexagonal cap 1.

The hexagonal cap 1 and the conical head 3 are connected as a whole, which can be formed by machining at one time, or can be formed by welding the hexagonal cap and the conical head.

Fig. 3-Fig. 5 are structural sectional views of an auxiliary thread-taking puller device in this embodiment.

In the event that the broken end of the screw cannot be taken out, just insert the hexagonal cap with the conical head of the device of the present invention, align the two small hexagonal bolts with the broken head screw, and then use a wrench to screw the two small hexagonal bolts respectively. Hexagonal, let the two small hexagonal bolts run towards each other until they meet the broken head screw, and continue to tighten the small hexagonal bolt; after the two small hexagonal bolts are tightened, use a wrench to screw the hexagonal The force applied to the broken cap screw, the broken cap screw is loosened until the broken cap screw is taken out.

When the broken head screw is short, the end face of the hexagon cap close to the small hexagon bolt can be inserted into the broken head screw to take the screw; when the broken head screw is long, the end of the conical head farther away from the small hexagon bolt can be used. Insert the broken head screw into the face to take the screw; as shown in Figure 2.
