technical field

The utility model relates to the technical field of mechanical tools, in particular to a double-sided ring wrench.

Background technique

The information disclosed in the background technology of the utility model is only intended to increase the understanding of the general background of the utility model, and is not necessarily regarded as an acknowledgment or in any form to imply that the information constitutes the prior art known to those skilled in the art .

A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. The wrench is usually formed with a clamping handle at one or both ends of the handle to apply an external force to the handle to twist the bolt or nut to hold the opening or sleeve of the bolt or nut. When in use, an external force is applied to the shank in the direction of thread rotation, so that the bolt or nut can be twisted.

The existing ring wrench is single-head and single-use, and can only be disassembled by using two types of objects to be fastened. The use has limitations. When the operator performs maintenance and disassembly, he needs to use wrenches of various sizes, which is not conducive to Carrying by the maintenance worker, the wrench needs to be replaced according to different objects to be fastened during use, which reduces the work efficiency.

Utility model content

The technical problem to be solved by the utility model is to overcome the above technical defects and provide a double-sided plum blossom wrench with various models.

In order to solve the above-mentioned technical problems, the technical solution provided by the utility model is: comprising a handle, a first extension part and a second extension part arranged at both ends of the handle, the feature is that the first extension part and the second extension part Both are cylindrical, and the two ends are small and the middle is large. The first extension part is provided with a first round hole, and the second extension part is provided with a second round hole. The inside of the first round hole and the second round hole The inner wall of the hole is provided with tooth openings, and the centerline of the horizontal axis in the first circular hole is provided with a first limit dividing part, and the first circular hole is divided into a first upper clamping part and a first lower clamping part. As for the tightening part, the center line of the horizontal axis in the second circular hole is provided with a second limit division part, and the second circular hole is divided into a second upper clamping part and a second lower clamping part.

As an improvement, both sides of the handle are provided with scale marks at the ends of the first extension part and the second extension part.

As an improvement, the size scale marks on one side are 17 and 22, and the size scale marks on the other side are 19 and 24.

Beneficial effect, the advantage of the utility model compared with the existing technology is that: the utility model has four clamping devices of different sizes on the wrench, which is convenient when the operator disassembles the object to be fastened. Use heads of different sizes can be replaced at any time, reducing the frequency of replacement and improving work efficiency.

detailed description

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

A double-sided torx wrench, comprising a handle 1, a first extension 2 and a second extension 3 arranged at both ends of the handle 1, characterized in that: the first extension 2 and the second extension 3 are Cylindrical, with small ends and a large middle, the first extension 2 is provided with a first round hole 4, the second extension 3 is provided with a second round hole 5, the inside of the first round hole 4 and The inner wall of the second circular hole 5 is provided with tooth openings 6, and the center line of the horizontal axis in the first circular hole 4 is provided with a first limit dividing part 7, and the first circular hole 4 is divided into first upper and lower The clamping part 401 and the first lower clamping part 402, the horizontal axis centerline in the second circular hole 5 is provided with a second limit division part 8, and the second circular hole 5 is divided into a second upper clamping part 501 and the second lower clamping part 502.

Both sides of the handle 1 are provided with scale marks 9 at the ends of the first extension part 2 and the second extension part 3 .

Wherein the size scale marks 9 on one side are 17 and 22, and the size scale marks 9 on the other side are 19 and 24.

When the utility model is specifically implemented,

When the operator is disassembling and assembling the object to be fastened, according to the size of the object to be fastened, find the first extension 2 or the second extension 3 of the corresponding size scale mark 9 on the front and back of the handle 1, It is convenient to replace the use heads of different sizes at any time, reduce the frequency of replacement, and then limit the fastening objects with the first round hole 4 or the second round hole 5, and then the operator holds the handle and rotates the handle clockwise or counterclockwise 1. Disassemble or fix the object to be fastened to improve work efficiency.

The utility model and its implementations have been described above. This description is not restrictive, and what is shown in the drawings is only one of the implementations of the utility model, and the actual structure is not limited thereto. All in all, if a person of ordinary skill in the art is inspired by it, without departing from the purpose of the utility model, without creatively designing a structural method and embodiment similar to the technical solution, it shall belong to the protection of the utility model scope.
