Description

Technical Field

[0001] This utility model relates to the field of hex wrench technology, and in particular to an anti-disengagement hex wrench. Background Technology

[0002] With the rapid development of modern industry, hexagonal fasteners are widely used in the manufacturing industries of automobiles, aircraft, machinery, and furniture. Hexagonal fasteners offer advantages such as ease of tightening and loosening, and resistance to stripping. Tightening and loosening hexagonal fasteners are inseparable from hexagonal wrenches. The six contact surfaces between the hexagonal fastener and the hexagonal wrench ensure sufficient force distribution and prevent damage. Hexagonal wrenches are simple, lightweight, and can be used to tighten fasteners in deep holes, making them an indispensable and powerful tool in industrial manufacturing.

[0003] An existing patent (publication number: CN216883683U) proposes a lightweight multi-functional hex wrench with different sizes of hex wrench functions at both ends. The interior of both ends has hex holes to accommodate small hex bits, and when used with small hex bits, it can have the functions of up to six sizes of hex wrench.

[0004] The problem with the above solution is that the hex wrench is just a simple rod shape. In actual use, the small contact area between the rod and the hand makes it difficult to apply force, resulting in poor tightening effect when tightening fasteners. Furthermore, the hexagonal face of a traditional hex wrench is flat. When it comes into contact with fasteners, if the fastener has a rounded edge, it is easy to cause "stripping" during the tightening process. Therefore, we propose an anti-disengagement hex wrench to solve the above problems. Utility Model Content

[0005] This utility model provides an anti-disengagement hex wrench, which solves the technical problem that current hex wrenches cannot provide sufficient force for tightening, resulting in poor tightening effect.

[0006] To solve the above-mentioned technical problems, this utility model provides an anti-disengagement hex wrench, including a hex wrench body, an anti-slip handle detachably provided along the length of the hex wrench body, a hexagonal slot on the anti-slip handle, positioning grooves on both sides of the hexagonal slot, a positioning baffle fixed along the length of the hex wrench body, and a fastening ring sleeve fitted on the hex wrench body, the fastening ring sleeve being threadedly connected to the anti-slip handle.

[0007] Preferably, the end of the hex wrench shaft away from the anti-slip handle is also provided with an anti-slip groove.

[0008] The above technical solution is adopted: the end of the Allen wrench shaft away from the anti-slip handle is also provided with an anti-slip groove. When the fastener has a rounded edge, the anti-slip groove can prevent the Allen wrench from slipping when tightening the fastener, thus increasing the gripping force of the Allen wrench relative to the fastener.

[0009] Preferably, the size of the hexagonal slot is adapted to the size of the internal hexagonal wrench body, and the size of the positioning groove is adapted to the size of the positioning baffle.

[0010] The above technical solution is adopted by matching the size of the hexagonal slot with the size of the internal hexagonal wrench shaft, and matching the size of the positioning groove with the size of the positioning baffle.

[0011] Preferably, an external thread is provided at one end of the anti-slip handle, and an internal thread is provided inside the fastening ring sleeve.

[0012] The above technical solution is adopted: an external thread is provided at one end of the anti-slip handle, and an internal thread is provided inside the fastening ring sleeve.

[0013] Preferably, the anti-slip handle is provided with anti-slip texture, and the anti-slip texture is arranged in an array along the length direction of the anti-slip handle.

[0014] The above technical solution is adopted: the anti-slip handle is provided with anti-slip texture, and the anti-slip texture is arranged in an array along the length direction of the anti-slip handle.

[0015] Preferably, the anti-slip grooves are provided in three parts.

[0016] The above technical solution involves creating three anti-slip grooves.

[0017] Preferably, the end of the anti-slip handle away from the fastening ring is detachably provided with a hammer body.

[0018] The above technical solution is adopted: a hammer body is detachably installed at the end of the anti-slip handle away from the fastening ring.

[0019] Preferably, a post is fixed on the hammer body, the post is inserted into the anti-slip handle, a fixing pin is inserted on the anti-slip handle and the post, and an anti-slip pin is provided on the fixing pin.

[0020] The above technical solution is adopted as follows: a post is fixed on the hammer body, the post is inserted into the anti-slip handle, a fixing pin is inserted on the anti-slip handle and the post, and an anti-slipping device is provided on the fixing pin.

[0021] Preferably, the hammer body is cone-shaped.

[0022] The above technical solution is adopted: the hammer body is cone-shaped.

[0023] Preferably, a socket hole is provided on the fastening ring sleeve, the diameter of the socket hole being larger than the diameter of the Allen wrench body, and the diameter of the socket hole being smaller than the sum of the length of the Allen wrench body and the positioning baffles on both sides.

[0024] The above technical solution is adopted by providing a socket hole on the fastening ring sleeve. The diameter of the socket hole is larger than the diameter of the Allen wrench body, and the diameter of the socket hole is smaller than the sum of the length of the Allen wrench body and the positioning baffles on both sides.

[0025] Compared with related technologies, this utility model has the following beneficial effects:

[0026] 1. Compared to traditional hex wrenches, this utility model features an anti-slip handle. The anti-slip handle is detachably mounted along the length of the hex wrench shaft. The anti-slip handle has a hexagonal slot with positioning grooves on both sides. A positioning baffle is fixed along the length of the hex wrench shaft. A fastening ring is also fitted onto the hex wrench shaft, threadedly connected to the anti-slip handle. The handle and the hex wrench shaft are perfectly matched, making disassembly and installation very convenient. In actual use, the anti-slip handle is fitted onto the hex wrench shaft, engaging the positioning groove on the anti-slip handle with the positioning baffle on the hex wrench shaft. Then, the fastening ring is fitted onto the other end of the hex wrench shaft and threadedly connected to the anti-slip handle. This makes it easier to apply force when using the hex wrench, resulting in a better tightening effect on fasteners.

[0027] 2. In this utility model, by providing anti-slip grooves, when the fastener has a rounded edge, the anti-slip grooves grip the rounded edge of the fastener, preventing the hex wrench from slipping when turning the fastener, and increasing the gripping force of the hex wrench relative to the fastener.
