Description

Technical Field

[0001] The utility model relates to the field of wrenches, and particularly to a dual-purpose wrench with an anti-slip function. Background Technique

[0002] In mechanical maintenance, equipment installation and daily tool use, as a commonly used manual tool, the performance of a wrench directly affects work efficiency and operation safety. The design of traditional wrenches often only adapts to nuts of specific sizes, lacking universality and flexibility. In addition, in a humid, greasy or corrosive environment, the friction between the wrench and the nut decreases, easily causing the wrench to slip off, which not only affects the operation efficiency but may also pose a safety hazard.

[0003] To solve the above problems, some improved wrenches have emerged in the market, such as wrenches with anti-slip patterns and wrenches with adjustable opening sizes. However, these wrenches still have deficiencies in anti-slip performance and universality. Although the anti-slip patterns can increase the friction to a certain extent, the effect is limited under extreme conditions; while the wrenches with adjustable opening sizes, although improving universality, have complex structures, high costs, and cumbersome adjustment processes. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dual-purpose wrench with an anti-slip function to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A dual-purpose wrench with an anti-slip function, including a first wrench body. At both ends of the first wrench body, there are respectively a first opening and a second opening. A wear-resistant alloy strip is fixed on the surface of the first opening, and a rubber plug strip is embedded on the surface of the second opening. A rubber clip is provided on the surface of the first wrench body, and after the rubber clip is folded, it can be inserted into the second opening.

[0006] Preferably, the wear-resistant alloy strip is in the shape of an isosceles trapezoid strip. There are multiple wear-resistant alloy strips, and the multiple wear-resistant alloy strips are arranged equidistantly and equally sized along the side wall of the first opening.

[0007] Preferably, an embedding groove is opened on the surface of the second opening. The embedding groove is in the shape of a "U" - shaped groove. The rubber plug strip is fixed in the embedding groove, and the rubber plug strip protrudes from the embedding groove.

[0008] Preferably, the thickness of the rubber plug strip is less than the height of the embedding groove.

[0009] Preferably, a notch is opened on the surface of the first wrench body. The notch is in the shape of a "middle" - shaped groove. The notch is connected to the second opening. The rubber clip is in the shape of a "middle" - shaped plate - like structure, and one end of the rubber clip is fixed on the surface of the notch close to the second opening.

[0010] Preferably, a stop strip is fixed to the surface of the wrench body, the stop strip covers the top of the notch, and after the rubber clip is inserted into the notch, the stop strip blocks the top of the rubber clip.

[0011] Preferably, the surface of the wrench body is provided with a slot, and the slot and the notch are connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model proposes a dual-purpose wrench with anti-slip function. Multiple wear-resistant alloy strips are fixed to the surface of the opening of the wrench body, forming a circumferentially arranged rib structure. This not only increases the wear resistance of the opening but also allows the wrench to adapt to nuts of different profiles. Simultaneously, the anti-slip effect of the wear-resistant alloy strips significantly improves the friction between the wrench and the nut, maintaining a stable grip even in humid, oily, or corrosive environments.

[0014] The second opening design combines a dual anti-slip mechanism of rubber plug and rubber clip. The way the rubber plug is fixed in the groove allows it to spring back and press tightly against the nut surface when compressed by the nut, increasing the friction between the second opening and the nut. Meanwhile, the foldable design of the rubber clip allows the second opening to fit smaller nuts, greatly improving the wrench's versatility and adaptability.

[0015] The notched groove, retaining strip, and pull-out groove design make it easier and faster to remove and fold the rubber clip. At the same time, these features also facilitate cleaning and maintenance of the wrench after use, extending its service life. Attached Figure Description

[0021] In order to clearly and completely describe the purpose and technical solution of the present utility model and make its advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments. They are only used to explain the embodiments of the present utility model and are not used to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a dual-purpose wrench with an anti-slip function, including a wrench body 1. Both ends of the wrench body 1 are respectively provided with an opening 1 2 and an opening 2 4. A wear-resistant alloy strip 3 is fixed on the surface of the opening 1 2. The wear-resistant alloy strip 3 is in the shape of an isosceles trapezoidal strip. There are multiple wear-resistant alloy strips 3, and multiple wear-resistant alloy strips 3 are arranged equidistantly and in equal size along the side wall of the opening 1 2. The reason for installing the wear-resistant alloy strip 3 inside the opening 1 2 is to increase the wear resistance of the opening 1 2, and multiple wear-resistant alloy strips 3 form a circumferentially arranged rib, so that the opening 1 2 is adapted to nuts with different contours for use. At the same time, the wear-resistant alloy strip 3 plays an anti-slip role between the opening 1 2 and the nut.

[0023] A rubber plug strip 6 is embedded on the surface of the opening 2 4. An embedding groove 5 is opened on the surface of the opening 2 4. The embedding groove 5 is in the shape of a "U" - shaped groove. The rubber plug strip 6 is fixed in the embedding groove 5, and the rubber plug strip 6 protrudes from the embedding groove 5. The thickness of the rubber plug strip 6 is less than the height of the embedding groove 5. The reason for embedding the rubber plug strip 6 inside the opening 2 4 is that after the opening 2 4 is sleeved on the nut, at this time, the rubber plug strip 6 is compressed into the embedding groove 5, and the rubber plug strip 6 rebounds and tightly abuts between the opening 2 4 and the nut, increasing the friction between the opening 2 4 and the nut, that is, playing an anti-slip role between the opening 2 4 and the nut.

[0024] A rubber clip 8 is provided on the surface of the wrench body 1. After being folded, the rubber clip 8 can be inserted into the opening 2 4. A notch 7 is opened on the surface of the wrench body 1. The notch 7 is in the shape of a "middle" - shaped groove. The notch 7 is connected to the opening 2 4. The rubber clip 8 is in the shape of a "middle" - shaped plate structure. One end of the rubber clip 8 is fixed on the surface of the notch 7 close to the opening 2 4. A retaining strip 9 is fixed on the surface of the wrench body 1. The retaining strip 9 covers above the notch 7. After the rubber clip 8 is inserted into the notch 7, the retaining strip 9 blocks above the rubber clip 8. A picking groove 10 is opened on the surface of the wrench body 1. The picking groove 10 is connected to the notch 7.

[0025] When the groove size of opening 2 4 is larger than the outline size of the nut, the rubber clip 8 is pulled out from the notch 7, the pulled-out rubber clip 8 is turned outward and inserted into opening 2 4, and then opening 2 4 is fastened on the nut. At this time, the rubber clip 8 is clamped between opening 2 4 and the nut to fill the gap, so that opening 2 4 can be used with a smaller nut.

[0026] The detailed procedure for using a dual-purpose wrench with anti-slip function is as follows:

[0027] Observe the outline dimensions of the nut to be tightened or loosened. Check the two openings on the wrench body 1: opening 2 and opening 4. When using opening 2, the nut outline dimensions should match or be slightly smaller than opening 2. Align opening 2 with the nut. Use the wear-resistant alloy strip 3 to increase friction and fit, ensuring the wrench is stable and does not slip. Apply appropriate force to operate (tighten or loosen). When using opening 4 (direct fit), the nut outline dimensions should directly match opening 4.

[0028] Align opening 2 (4) with the nut. The rubber plug 6 will slightly retract into the groove 5 when pressed by the nut, then spring back to press firmly against the nut surface, increasing the anti-slip effect. Apply appropriate force during operation. When using opening 2 (4) (adapted to small-sized nuts via rubber clip 8), when the nut's profile is smaller than the groove size of opening 2 (4), gently pull the rubber clip 8 out of the notch 7. Fold the rubber clip 8 outwards, preparing to insert it into opening 2 (4). Align opening 2 (4) with the nut, ensuring the rubber clip 8 is properly clamped between opening 2 (4) and the nut. Insert the folded rubber clip 8 into opening 2 (4), filling the gap between opening 2 (4) and the nut. Ensure the rubber clip 8 is securely clamped between opening 2 (4) and the nut.

[0029] Apply appropriate force to operate.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
