Description

Technical Field

[0001] The utility model belongs to the technical field of hardware tools, and particularly relates to a wrench with replaceable wrench heads. Background Art

[0002] A wrench is a commonly used installation and disassembly tool. It is a manual tool that uses the lever principle to turn screws, nuts, and bolts, and is indispensable in the mechanical field. In daily life, it is often used to install or disassemble bolts of different specifications. Generally, a large number of wrenches of various models are required. That is, the existing wrenches can only be used for one corresponding bolt. When disassembling or installing different bolts or nuts, different models of wrenches need to be constantly replaced, wasting a lot of valuable time, having low work efficiency, occupying space, and being inconvenient to carry. Content of the Utility Model

[0003] The purpose of the utility model is to address the above problems existing in the prior art, and to propose a tool wrench with a simple structure and easy-to-detach replaceable wrench heads, which has the advantage of being convenient to replace the wrench heads, and solves the problems that the existing wrenches are large in volume and weight, and it is inconvenient to carry multiple wrenches at the same time.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A wrench with replaceable wrench heads, characterized in that: it includes a T-shaped handle and a detachable wrench head; the T-shaped handle is provided with a cross bar and a vertical bar, a T-shaped groove is provided at the end of the vertical bar, the detachable wrench head is provided with a T-shaped boss and a wrench head, and the T-shaped handle and the detachable wrench head are connected through the T-shaped groove and the T-shaped boss.

[0006] Further, both the cross bar and the vertical bar are cylindrical, and the cross bar and the vertical bar are fixedly welded.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] 1. The T-shaped handle and the detachable wrench head of the utility model are detachable. During use, when it is necessary to replace the wrench heads of different specifications and sizes, only the detachable wrench head needs to be pulled out of the T-shaped groove by hand for replacement, and the installation and disassembly are relatively convenient. Compared with the traditional integral wrench, the T-shaped handle of this design can be reused. When the wrench head is damaged, there is no need to discard the entire wrench, and only the wrench head needs to be replaced separately, which can better avoid waste of raw materials, effectively reduce costs, and is environmentally friendly and economical.

[0009] 2. The detachable wrench head of the utility model can also be designed into two types of wrench heads: external hexagon wrench heads and internal hexagon wrench heads, with strong applicability. Description of the Drawings

[0016] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] As shown in the attached Figure 1 to the attached Figure 4 As shown, the detachable wrench of the present embodiment is composed of a T-shaped handle 1 and a detachable wrench head 2. A T-shaped groove 121 is provided at the end of the vertical bar 12 of the T-shaped handle 1, and the detachable wrench head 2 is provided with a T-shaped boss 21. The sizes of the T-shaped groove 121 and the T-shaped boss 21 are the same. During installation, first align the T-shaped boss 21 of the detachable wrench head 2 with the T-shaped groove 121 at the end of the vertical bar 12, and then simply insert it into the T-shaped groove 121 by hand. Since the wrench is only subjected to torsion during the process of screwing the screw, the detachable wrench head 2 does not need to be fixed with screws, making the installation and disassembly convenient and fast.

[0018] A specific application of this embodiment is as follows: When in use, the operator first inserts the detachable wrench head 2 into the T-shaped groove 121 at the end of the vertical bar 12, so that the outer surface of the T-shaped boss 21 fits against the inner wall of the T-shaped groove 121. At this time, the detachable wrench head 2 and the vertical bar 12 are coaxially centered, and the detachable wrench head 2 is installed, as shown in the attached Figure 1 As shown. Then insert the detachable wrench head 2 into the bolt or nut that needs to be tightened or loosened, and hold the cross bar 11 on the T-shaped handle 1 with both hands and rotate, then the purpose of tightening or loosening the bolt or nut can be achieved. When it is necessary to tighten or loosen bolts or nuts of different specifications, simply pull out the detachable wrench head 2 radially by hand first, and then insert the corresponding detachable wrench head 2 to complete the replacement of the detachable wrench head 2, which is convenient and fast.

[0019] In the present utility model, the detachable wrench head 2 can also be designed into two types of wrench heads: an external hexagonal wrench head and an internal hexagonal wrench, as shown in the attachedFigure 3 and attached Figure 4 As shown, the applicability of this wrench is enhanced, enabling a single T-shaped handle to correspond to multiple and various wrench heads. This solves the problem that existing wrenches are relatively large in volume and weight, making it inconvenient to carry multiple wrenches simultaneously. At the same time, the T-shaped handle 1 and the detachable wrench head 2 are made of different materials. The T-shaped handle 1 is made of low-carbon steel with relatively soft hardness and good toughness, while the detachable wrench head 2 is made of medium-carbon steel or high-carbon steel with relatively high hardness. The T-shaped handle 1 can be reused. If the detachable wrench head 2 is damaged or lost, only the corresponding detachable wrench head 2 needs to be manufactured separately. Compared with traditional wrenches, it can not only achieve "one-to-many", but also better avoid waste of raw materials, effectively reduce costs, and be environmentally friendly and economical.

[0020] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
