Description

1. Area of ​​the utility model

[0001] The present utility model relates to a wrench, in particular a wrench which can prevent the penetration of fasteners and has a multidirectional penetration protection effect. 2. Description of the state of the art

[0002] A conventional wrench is used by a user to tighten or loosen fasteners such as screws or nuts. Conventional wrenches include open-end wrenches, box-end wrenches, socket wrenches, combination wrenches, adjustable wrenches, ratchet wrenches, pipe wrenches, and other types. A conventional wrench has a clamping surface formed axially through the wrench head on the inside of the wrench head, with a contour that matches the shape of the fastener. The fastener is rotated by the clamping surface, which engages with the fastener when the conventional wrench is turned.Although a conventional wrench can achieve a tightening or loosening effect on the fasteners, the wrench head of the conventional wrench only contacts an outer surface of the fastener.When a conventional wrench is used to turn the fastener, the clamping surface of the wrench head may not be aligned with the outer surface of the fastener, or the wrench head may pass through the fastener when placed around it. This prevents the conventional wrench from accurately tightening or loosening the fastener, requires the wrench head to be repeatedly aligned with the fastener to turn it, and prevents the wrench head from being firmly positioned on the fastener, increasing inconvenience during use.

[0003] To solve the aforementioned problems, a connecting recess is formed in the upper surface of the wrench head during the manufacturing process, and a positioning plate is placed within this recess. The positioning plate has an inner edge that protrudes from the clamping surface of the wrench head, allowing its underside to rest against the top surface of the fastener when the conventional wrench is applied. This stabilizes the wrench head and prevents it from penetrating the fastener.Although the wrench head of a conventional wrench can be stably positioned on the fastener by the positioning plate, manufacturing the conventional wrench requires machining the connecting recess and producing the positioning plate. After manufacturing, the positioning plate must be secured in the connecting recess to prevent the wrench head from penetrating the fastener. This increases manufacturing time and costs. Furthermore, the structural strength of the positioning plate is easily compromised by structural damage or loosening after prolonged use, causing the positioning plate to detach from the wrench head. Consequently, the conventional wrench can no longer stabilize the wrench head and prevent penetration of the fastener.Furthermore, although the conventional wrench can exert a positioning effect on the fasteners through the positioning plate that rests against them, the positioning plate can only rest in one direction and is not able to rest in different directions, which relatively limits the practicality of the conventional wrench.

[0004] Furthermore, since the contour of the clamping surface of the conventional wrench head corresponds to the shape of the fastener, the conventional wrench must be rotated a certain angle (e.g., 60°) before the fastener can be tightened or loosened. Due to the large range of rotation, sufficient space is required, and multiple turns are necessary to tighten or loosen the fastener, which relatively increases the time required to operate the conventional wrench and necessitates further improvement.

[0005] To remedy these shortcomings, the present utility model aims to provide a wrench with multidirectional penetration protection to mitigate the aforementioned problems.

[0006] The main objective of the utility model is to provide a wrench that can prevent the penetration of fasteners and has a multidirectional penetration protection effect.

[0007] A wrench with multidirectional penetration protection according to the present utility model comprises a body, at least one wrench head, and at least two abutting units. The at least one wrench head is formed at one end of the body and has at least one engagement section located on an inner surface of the at least one wrench head. Each of the at least one engagement sections has two engagement surfaces connected to each other at an enclosed angle and located between a top and a bottom surface of the at least one wrench head. The at least two abutting units are formed by transverse punching on the top and bottom surfaces of the at least one wrench head and project from the inner surface of the at least one wrench head.The abutting units are arranged offset from each other along an axial direction of the at least one wrench head.

[0009] With reference to the Fig. 1 and Fig. 2 comprises a first embodiment of a wrench with multidirectional penetration protection effect according to the present utility model a body 10, at least one wrench head 20 and at least two abutting units 30A, 30B.

[0010] The body 10 is an elongated plate. The at least one wrench head 20 is formed as a single part at one end of the body 10 or connected to the end of the body 10 by a connecting element. Preferably, the wrench in the present utility model application has two wrench heads 20, each arranged at opposite ends of the body 10, and each of the two wrench heads 20 is closed and has multiple engagement sections 23 arranged on an inner side of the wrench head 20. Each engagement section 23 has two interconnected engagement surfaces 231. Each of the two engagement surfaces 231 is arranged longitudinally on the inner side of the at least one wrench head 20 between a top surface 21 and a bottom surface 22 of the at least one wrench head 20.Furthermore, the two engagement surfaces 231 extend through the top 21 and the bottom 22 of the at least one wrench head 20, and an enclosed angle is formed between the two engagement surfaces 231. In the first embodiment of the present utility model, each wrench head 20 has an even number of engagement sections 23 arranged on the inside of the wrench head 20. Preferably, this even number is eight, ten, or twelve, etc. If the wrench head 20 has twelve engagement sections 23, the engagement sections 23 can be arranged in a ring shape on the inside of the wrench head 20 at an angle of 30°.

[0011] The at least two abutting units 30A, 30B are integrally formed on the at least one wrench head 20. One of the at least two abutting units 30A is arranged transversely on the upper surface 21 of the at least one wrench head 20 and is located between the two engagement surfaces 23 of one of the engagement sections 23, and the other of the at least two abutting units 30B is arranged transversely on the lower surface 22 of the at least one wrench head 20 and is located between the two engagement surfaces 23 of one of the engagement sections 23. With reference to Fig. In the 3-part abutting unit 30B on the underside 22 and the abutting unit 30A on the top side 21 of the at least one wrench head 20 are offset from each other along an axial direction C of the at least one wrench head 20. That is, the two abutting units 30A, 30B do not overlap along the axial direction C. Preferably, the wrench has multiple abutting units 30A, 30B arranged on both the top side 21 and the underside 22 of the wrench head 20, and the abutting units 30A on the top side 21 and the abutting units 30B on the underside 22 are arranged offset from each other along the axial direction C of the wrench head 20.Furthermore, the at least two abutting units 30A, 30B can optionally be arranged on one of the top 21 and bottom 22 of the at least one wrench head 20.

[0012] With reference to Fig. 3 In the first embodiment of the present utility model, a small punching head 50, which is aligned with the inclination angle of a corresponding engagement section 23, is moved from the top 21 to the bottom 22 of the wrench head 20 in the direction of the wrench head 20 in order to punch the top 21 of the wrench head 20 (riveted outer extrusion) in order to form the said abutting unit 30A at the inclination angle of the corresponding engagement section 23.Furthermore, the small punching head 50, aligned with the inclination angle of another corresponding engagement section 23, is moved from the underside 22 to the top 21 of the wrench head 20 in the direction of the wrench head 20 to punch the underside 22 of the wrench head 20, which is deformed to form the said abutting unit 30B at the inclination angle of the corresponding engagement section 23, and the two abutting units 30A, 30B are offset from each other. Moreover, each of the two abutting units 30A, 30B can be formed at any position along the inclination angle of the corresponding engagement section 23, for example, at the apex of the angle or along its sides; this is not limited to a specific location.Additionally, a single small punching head 50 can be used in the utility model to form the two abutting units 30A, 30B. Specifically, the small punching head 50 can first be used to form the abutting unit 30A on the top 21 of the wrench head 20, and then, after turning the wrench head 20 over, the same small punching head 50 can be used to form the abutting section 30B on the bottom 22. Furthermore, multiple small punching heads 50 can be used in a production line to simultaneously form both abutting sections 30A, 30B on the wrench head 20. The specific punching process and method are not restricted as long as the two abutting sections 30A, 30B are formed on the wrench head 20.

[0013] With reference to the Fig. 4 and Fig. In the first embodiment of the present utility model, a fastening element 40 is inserted into the inside of the wrench head 20 from the underside 22, and each of the corners 41 of the fastening element 40 is moved into one of the engagement sections 23 so that the two engagement surfaces 231 of the corresponding engagement section 23 can bear against two sides of the corresponding corner 41. Furthermore, an upper surface of the fastening element 40 abuts the abutting unit 30A, which is arranged on the upper surface 21 of the wrench head 20, at the corresponding engagement section 23. Then, the at least one wrench head 20 can be stably connected to the fastening element 40 to prevent the at least one wrench head 20 from penetrating the fastening element 40.This means that the corresponding corner 41 of the fastening element 40 is simultaneously engaged by the two engagement surfaces 231 of the corresponding engagement section 23 and the abutting unit 30A on the top 21 of the wrench head 20, enabling the wrench of the first embodiment of the present utility model to lock or release the fastening element 40 stably without penetration.Since the two abutting units 30A, 30B on the top 21 and the bottom 22 of the wrench 20 are offset from each other, when the locking element 40 is inserted into the inside of the wrench head 20 via the bottom 22 of the wrench head 20, the top of the fastening element 40 can be offset from the abutting unit 30B located on the bottom 22, and then extend into the inside of the wrench head 20 to abut the abutting unit 30A located on the top 21.

[0014] Similarly, as in the Fig. 6 and Fig. Figure 7 shows that, in the first embodiment of the present utility model with an inverted wrench head 20, the fastening element 40 is arranged on the inside via the top 21 of the wrench head 20. Each of the corners 41 of the fastening element 40 is moved to one of the engagement sections 23, and the two engagement surfaces 231 of each engagement section 23 abut the sides of a corresponding corner 41. The top of the fastening element 40 at the engagement section 23 also abuts the abutting unit 30B arranged on the bottom 22 of the wrench head 20. This ensures that the wrench head 20 is firmly connected to the fastening element 40, thus preventing the wrench head 20 from penetrating the fastening element 40.In other words, the corner 41 of the fastening element 40 is held in position by the two engagement surfaces 231 of the engagement section 23 and the stop section 30B, whereby the first embodiment of the present utility model can securely lock or release the fastening element 40 without penetrating it.

Furthermore, the two engagement surfaces 231 extend through the top surface 21 and the bottom surface 22 of the at least one wrench head 20B, and an enclosed angle is formed between the two engagement surfaces 231.In the second embodiment of the present utility model, each clamping jaw 26, 27 has one of the engagement sections 23, and the two engagement sections 23 of the two clamping jaws 26, 27 are arranged opposite each other. The at least one wrench head 20B has a curved section 28 that is arranged between the two engagement sections 23 of the two clamping jaws 26, 27. In addition, each of the two clamping jaws 26, 27 has a non-slip surface 29 that is arranged on the inside of the respective clamping jaw 26, 27 next to the end section 261, 271.

[0016] The at least two abutting units 30A, 30B are integrally formed on the at least one wrench head 20B, are arranged transversely on the upper surface 21 of the at least one wrench head 20B, and are each arranged at the angles of inclination of the engagement sections 24 of the two clamping jaws 26, 27.

[0017] With reference to the Fig. 9A and Fig. In the second embodiment of the present utility model, a small punching head 50, aligned with the inclination angle of a corresponding engagement section 23, is moved from the top 21 to the bottom 22 of the wrench head 20B in the direction of the wrench head 20B to punch the top 21 of the wrench head 20B (riveted outer extrusion) in order to form the said abutting units 30A, 30B at the inclination angle of the corresponding engagement section 23. With reference to Fig. 10. In the second embodiment of the present utility model, a fastening element 40 is arranged between the two clamping jaws 26, 27 above the jaw, and each of the two non-slip surfaces 29 of the two clamping jaws 26, 27 abuts one of the sides of the fastening element 40 to prevent the fastening element 40 from detaching from the two clamping jaws 26, 27 above the jaw when the at least one wrench head 20B is turned. Furthermore, with reference to Fig. 11. When the at least one wrench head 20B is rotated relative to the fastening element 40, one of the corners 41 of the fastening element 40 moves into the engagement section 23 of one of the two clamping jaws 26, 27, with the two engagement surfaces 231 of the corresponding engagement section 23 each abutting two sides of the corresponding corner 41, and a top surface 42 of the fastening element 40 abutting the at least one abutting unit 30A, 30B. Then the at least one wrench head 20B can be stably connected to the fastening element 40 to prevent the at least one wrench head 20B from penetrating the fastening element 40.This means that the corresponding corner 41 of the fastening element 40 is simultaneously brought into contact and engaged by the two engagement surfaces 231 of the corresponding engagement section 23 and the at least one abutting unit 30A, 30B, whereby the wrench of the second embodiment of the present utility model can lock or release the fastening element 40 stably without penetration.
