Description

Technical Field

[0001] The utility model belongs to the technical field of torque wrenches, in particular to an adjustable torque wrench. Background Art

[0002] A torque wrench is a wrench that can adjust the torque. Existing torque wrenches include a handle and a wrench head. The handle and the wrench head are an integrally formed structure. When the handle or the wrench head is deformed or damaged, it is impossible to replace them separately, and the entire handle or the wrench head is discarded, wasting the intact part.

[0003] The existing patent document (publication number: CN220007618U) discloses "a torque wrench", which also has the above-mentioned technical problems. Summary of the invention

[0004] The utility model aims to solve the above-mentioned technical problems existing in the prior art and to provide an adjustable torque wrench with a novel structure. The handle and the wrench head can be detached and separated to replace the one-piece molding structure. The damaged part can be replaced separately and the intact part can continue to be used.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The adjustable torque wrench includes a handle and a wrench head, and is characterized in that the wrench head is provided with a connecting end, one end of the handle is provided with a first set of holes corresponding to the connecting end, and the handle is fixedly connected to the connecting end through a first bolt; an anti-slip sleeve is provided on the handle, and the anti-slip sleeve covers the end of the first bolt. The torque wrench has a novel structure, and the handle and the wrench head can be detached and separated, replacing the integrally formed structure, and the damaged part can be replaced separately, and the intact part can continue to be used.

[0007] Furthermore, a positioning groove is provided on the connecting end, and a positioning protrusion corresponding to the positioning groove is provided on the inner wall of the first set of holes. The positioning groove is aligned with the positioning protrusion and inserted, which facilitates the alignment of the first countersunk hole on the handle with the threaded hole on the connecting end, reduces the difficulty of hole alignment, prevents relative rotation between the wrench head and the handle, and improves reliability of use.

[0008] Furthermore, threaded holes are evenly distributed on the connection end, a first countersunk hole communicating with the first set of holes is provided on the handle, a first bolt passes through the first countersunk hole and is threadedly connected to the threaded hole, and the end of the first bolt is located in the first countersunk hole. By connecting the first bolt to threaded holes at different horizontal positions, the length of the connection end entering the first set of holes can be changed, thereby changing the overall length, thereby meeting the requirements of the force arm length under different usage conditions, and having strong applicability.

[0009] Furthermore, a screwdriver is provided at the tail of the handle, and the provision of the screwdriver makes it convenient for the user to pry some small parts, thereby enriching the use function and improving the practicality.

[0010] Furthermore, the handle is fixedly connected to the screwdriver by the second bolt, the fixation is reliable, the two are not easily separated freely, the screwdriver is easy to disassemble and assemble, and can be used at any time, which is flexible and convenient.

[0011] Furthermore, the screwdriver is provided with a connecting portion, the tail end of the handle is provided with a second set of holes corresponding to the connecting portion, the connecting portion is provided with a fixing screw hole, the handle is provided with a second countersunk hole communicating with the second set of holes, the second bolt passes through the second countersunk hole and is threadedly connected to the fixing screw hole, and the end of the second bolt is located in the second countersunk hole. The screwdriver is connected to the second set of holes of the handle through the connecting portion, ensuring a sufficient connection area, thereby improving the connection reliability; the anti-slip cover covers the end of the second bolt, which not only protects the second bolt, preventing it from being damaged after being directly impacted by the outside and affecting subsequent disassembly, but also prevents the second bolt from freely escaping from the second countersunk hole.

[0012] Furthermore, the surface of the wrench head is coated with a wear-resistant layer, and the wear-resistant layer is made of a copper-zinc alloy layer, which improves the wear resistance of the wrench head, is not easy to wear, and has a long service life.

[0013] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0014] 1. The torque wrench adopts a split design. Compared with the integrated structure, it has lower manufacturing requirements. The damaged parts can be replaced separately, and the intact parts can continue to be used. During assembly, the connecting end is inserted into the first set of holes in the handle, and then the first bolt is screwed to the threaded holes at different horizontal positions. The length of the connecting end entering the first set of holes can be changed, thereby changing the overall length, thereby meeting the requirements of the force arm length under different usage conditions, and has strong applicability.

[0015] 2. Align the positioning groove with the positioning protrusion and snap it in, which is conducive to aligning the first countersunk hole on the handle with the threaded hole on the connecting end, reducing the difficulty of hole alignment, and preventing relative rotation between the wrench head and the handle, thereby improving the reliability of use.

[0016] 3. The setting of the screwdriver makes it easy for users to pry some small parts, enriches the use function and improves practicality; the screwdriver can be detached from the handle and can be used whenever you install it, which is flexible and convenient.
