Description

TECHNICAL FIELD

[0001] The utility model relates to a wrench, especially a wrench with the effect of preventing the penetration of locking members and multi-directional blocking. BACKGROUND

[0002] The existing wrench is used by the user to lock or loosen the locking member such as a bolt or a nut. The existing wrench has various types such as an open-end wrench, a closed-end wrench, a spanner wrench, a dual-purpose wrench, a movable wrench, a sleeve wrench, a ratchet wrench, and an oil pipe wrench, etc. The inner side surface of the wrench head of the existing wrench is axially penetrated to form a clamping surface corresponding to the profile of the locking member. The clamping surface is abutted against the locking member to rotate the locking member. However, the wrench head of the existing wrench can only abut against the outer peripheral surface of the locking member. Therefore, when the existing wrench is sleeved on the locking member to rotate the locking member, the clamping surface of the wrench head can be misaligned with the outer peripheral surface of the locking member or the wrench head can penetrate through the locking member. As a result, the existing wrench cannot accurately lock or loosen the locking member. The wrench head needs to be repeatedly aligned with the locking member to achieve the effect of rotating the locking member. The wrench head cannot be stably positioned on the locking member, which increases the inconvenience of use.

[0003] In view of the above problems, when manufacturing the existing wrench, a combination groove is recessed on the top surface of the wrench head, and a positioning plate is combined in the combination groove. The inner edge of the positioning plate extends beyond the clamping surface. When the existing wrench is sleeved on the locking member, the bottom surface of the positioning plate is abutted against the top surface of the locking member to provide the effect of stably positioning the wrench head to avoid the penetration of the locking member. Although the positioning plate can stably position the wrench head of the existing wrench with the locking member, the combination groove needs to be machined and the positioning plate needs to be added when manufacturing the existing wrench. After manufacturing, the positioning plate also needs to be fixed in the combination groove to avoid the penetration of the wrench head through the locking member. This not only increases the time and cost required for manufacturing, but also affects the structural strength of the positioning plate due to structural damage or loosening after long-term use, which causes the positioning plate to separate from the wrench head. The existing wrench cannot have the effect of stably positioning the wrench head to avoid the penetration of the locking member. Furthermore, the wrench head of the existing wrench can only abut against the locking member in a single direction by the positioning plate. The wrench head cannot abut against the locking member in different directions, which limits the practicality of the existing wrench.

[0004] Further, the clamping surface of the wrench head of the existing wrench corresponds to the profile of the locking member, so when the existing wrench rotates the locking member, it must be rotated by a certain angle (such as 60°) before it can be locked or loosened again. Not only does it require enough space to rotate due to the large rotation range, but it also needs to be rotated multiple times to achieve the effect of locking or loosening the locking member, which increases the time required to operate the existing wrench. In summary, the existing wrench still needs to be improved. Utility model content

[0005] Therefore, in view of the shortcomings and deficiencies of the existing wrench in actual operation, the present utility model has been developed through continuous testing and research. The multi-directional stopping effect wrench of the present utility model can be improved over the existing technology. The simplified structure setting method does not require additional machining of the combination groove and positioning plate, and can stably position the locking member and provide different directions of abutment, greatly improving the practicality of the wrench, thereby providing a multi-directional stopping effect wrench that can prevent the locking member from penetrating.

Also, the bottom surface of the wrench head is punched at the corresponding engaging portion's angle via the small punch along the bottom surface of the wrench head towards the top surface of the wrench head, so that the bottom surface of the wrench head is deformed by punching and then the other abutting portion is integrally formed at the angle.

[0012] Preferably, the multi-directional stoppage effect wrench as mentioned above, wherein the two engaging surfaces of each engaging portion are through the top surface and the bottom surface of the at least one wrench head.

[0013] Preferably, the multi-directional stoppage effect wrench as mentioned above, wherein the at least one wrench head has at least eight engaging portions formed on the inner side surface thereof in a circular arrangement.

[0014] Preferably, the multi-directional stoppage effect wrench as mentioned above, wherein the at least one wrench head has a ring groove circularly recessed between the top surface and the bottom surface on the inner side surface thereof, and a retaining ring is arranged in the ring groove.

[0016] Preferably, the multi-directional stoppage effect wrench as mentioned above, wherein the wrench has two wrench heads respectively arranged at two ends of the body.

[0017] In view of the above, the utility model provides a multi-directional stoppage effect wrench, which comprises a body, at least one wrench head and at least two abutting portions, wherein:

[0018] The body is a long strip-shaped plate body;

[0019] The at least one wrench head is arranged at one end of the body and has at least one engaging portion formed on the inner side surface thereof. The at least one engaging portion has two intersecting engaging surfaces, which are arranged between the top surface and the bottom surface of the at least one wrench head and form an angle therebetween; and

[0020] The at least one abutting portion is integrally formed on the at least one wrench head by punching. The at least one abutting portion is transversely arranged on the top surface of the at least one wrench head and extends out of the inner side surface of the at least one wrench head.

[0021] Preferably, the multi-directional stop effect wrench as disclosed above, wherein the at least one wrench head is in an open type and has two jaws connected and arranged face to face, forming a gap between two distal ends of the two jaws, and each of the two jaws is provided with at least one engaging portion on the inner side, and the wrench is provided with one abutting portion at the engaging portion of each of the two jaws, and each of the abutting portions is located at the intersection of the two engaging surfaces of the corresponding engaging portion and extends transversely from the intersection.

[0022] Preferably, the multi-directional stop effect wrench as disclosed above, wherein each of the two jaws is provided with an engaging portion, and the engaging portions of the two jaws are arranged face to face, and the at least one wrench head is provided with an arc portion between the adjacent engaging portions of the two jaws.

[0023] Preferably, the multi-directional stop effect wrench as disclosed above, wherein the top surface of the at least one wrench head is stamped at the intersection of the two engaging portions of the two jaws in the direction from the top surface of the at least one wrench head to the bottom surface of the at least one wrench head via a small punch to form the abutting portion integrally at the intersection after the top surface of the at least one wrench head is deformed by stamping.

[0024] Preferably, the multi-directional stop effect wrench as disclosed above, wherein the inner side of the at least one wrench head is stamped at the intersection of the two engaging portions of the two jaws in the direction from the bottom surface of the at least one wrench head to the top surface of the at least one wrench head via a large punch to form the abutting portion integrally at the intersection after the top surface of the at least one wrench head is deformed by stamping.

[0026] By utilizing the aforementioned technical features, this utility model's multi-directional stopping wrench, when in use, effectively prevents the wrench head from passing through the locking device by having at least one abutment extending inward from the top and bottom surfaces of the wrench head, respectively, to abut against the top surface of a locking device. This allows the wrench head to securely engage with the locking device during rotation, enabling locking or loosening operations, making it relatively convenient to use. Furthermore, the staggered arrangement of the abutment portions on the top and bottom surfaces allows the wrench head to have a bi-directional stopping effect on the locking device, significantly improving the wrench's practicality. Moreover, the abutment portions are formed by stamping the wrench head with a small punch (riveting-type external extrusion / cold-pressing-type internal extrusion). This invention eliminates the need for additional machining of the engagement groove and manufacturing of the positioning plate on the at least one wrench head. It not only integrally forms the aforementioned abutment portion on the at least one wrench head, thereby enhancing the structural strength of the at least one abutment portion, but also reduces the time and cost required for machining the engagement groove and manufacturing and assembling the positioning plate. This effectively prevents the positioning plate from separating from the engagement groove after prolonged use, thus affecting the anti-penetration effect. Furthermore, by providing several locking portions on the inner side of the at least one wrench head, this invention allows the user to lock or loosen the fastener by rotating the wrench at a small angle (e.g., 30°), significantly reducing the space and number of rotations required, and relatively reducing the operation time. This provides a wrench with a multi-directional blocking effect that prevents fastener penetration. Attached Figure Description
