Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to a wrench with a novel structure. Background Technology

[0002] In various scenarios such as industrial production, machinery repair, and home assembly, wrenches are core tools for tightening or loosening bolts, nuts, and other fasteners. Their performance and practicality directly affect work efficiency and ease of operation. Among them, fixed open-end wrenches have become a widely used basic tool type in daily work due to their significant advantages such as simple structure, low manufacturing cost, and compact size. Existing fixed open-end wrenches typically have wrench heads at both ends of the wrench handle. Each wrench head has a specific U-shaped or V-shaped opening, the size of which matches the corresponding bolt or nut size. Tightening or loosening is achieved by the contact between the head opening and the fastener, using the torque transmitted by the wrench handle. This design with fixed openings at both ends means that a single wrench can only accommodate two sizes of fasteners. When facing work scenarios with multiple fastener sizes, operators need to carry multiple wrenches of different sizes, increasing the burden of tool carrying and potentially reducing work efficiency due to frequent tool changes.

[0003] To address the limited compatibility of fixed open-end wrenches, some technical solutions attempt to improve their structure. Specifically, this involves creating multiple openings of different sizes on a single sheet of material (which can be considered a simplified integrated wrench handle and head structure), thus upgrading the single wrench's functionality to accommodate various fastener sizes. However, this improvement has practical limitations: because multiple openings must be concentrated on the same sheet of material, to ensure structural integrity and usable space, most openings cannot be located at the tool's end, but rather distributed in the middle or non-end areas of the material. This design flaw directly leads to the non-end openings being easily blocked by surrounding equipment components, structural frames, and other obstacles during operation, making it difficult to smoothly engage with the target fastener. Furthermore, in confined spaces, the operating space of non-end openings is further limited, preventing the tool from flexibly extending and finding the correct angle of force application. It may even prevent basic engagement due to space constraints, severely restricting the tool's applicability in complex working environments such as confined spaces. Utility Model Content

Fourth wrench heads 5 are fixedly connected to both outer walls of the second slider 3. The first wrench head 11 and the second... The second wrench head 15 is fixed, while the third wrench head 4 and the fourth wrench head 5 are movable. A first slider 2 enables a sliding connection between the third wrench head 4 and the first wrench head 11, and a second slider 3 enables a sliding connection between the fourth wrench head 5 and the second wrench head 15. A first through groove 13 restricts the first slider 2, preventing it from rotating, while a first through hole 14 provides space for the first slider 2 to rotate, allowing the third wrench head 4 to rotate. A second through groove 17 restricts the second slider 3, preventing it from rotating, while a second through hole 18 provides space for the second slider 3 to rotate, allowing the fourth wrench head 5 to rotate. First limiting grooves 44 are provided on the two third wrench heads 4 at positions corresponding to the first slider 2, and the first slider 2... The first slider 2 is fitted into the first limiting groove 44, which has a first mounting hole 43 connected to it. A first threaded hole 21 is provided on the first slider 2 at the position corresponding to the first mounting hole 43. A first screw 22 is installed in the first mounting hole 43 and threaded into the first threaded hole 21. The first limiting groove 44 prevents rotation between the third wrench head 4 and the first slider 2. The first mounting hole 43 and the first threaded hole 21 are used to install the first screw 22, which fixes the third wrench head 4 onto the first slider 2. Two fourth wrench heads 5 have second limiting grooves 54 at the positions corresponding to the second slider 3, and the second slider 3 is fitted into the second limiting grooves 54. The inner conductive connection has a second mounting hole 53. A second threaded hole 31 is provided on the second slider 3 at the position corresponding to the second mounting hole 53. A second screw 32 is installed in the second mounting hole 53 and the second screw 32 is threaded into the second threaded hole 31. The second limiting groove 54 is used to prevent the fourth wrench head 5 from rotating between the second slider 3 and the fourth wrench head 5. The second mounting hole 53 and the second threaded hole 31 are used to install the second screw 32. The fourth wrench head 5 is fixed on the second slider 3 by the second screw 32. A first opening 12 is provided at one end of the first wrench head 11 and a second opening 16 is provided at one end of the second wrench head 15. The first wrench head 11 is used to support the first opening 12 and the second wrench head 15 is used to support the second opening 16.One of the third wrench heads 4 has a third opening 41 at one end and a fourth opening 42 at the other end; another third wrench head 4 has a fifth opening 45 at one end and a sixth opening 46 at the other end. The third wrench head 4 is used to accommodate the third opening 41 and the fourth opening 42, and the other third wrench head 4 is used to accommodate the fifth opening 45 and the sixth opening 46. One of the fourth wrench heads 5 has a seventh opening 51 at one end and an eighth opening 52 at the other end; another fourth wrench head 5 has a ninth opening 55 at one end and a tenth opening 56 at the other end. The fourth wrench head 5 is used to accommodate the seventh opening 51 and the eighth opening 52, and the other fourth wrench head 5 is used to accommodate the ninth opening 55 and the tenth opening 56.

[0020] Working principle: When assembling and using this utility model, the first slider 2 is installed in the first through groove 13, and two third wrench heads 4 are respectively installed on both sides of the first slider 2, so that the first slider 2 is inserted into the first limiting groove 44. Then, the first screw 22 is installed in the first mounting hole 43 and screwed into the first threaded hole 21, thereby fixing the third wrench head 4 onto the first slider 2. Then, the second slider 3 is installed in the second through groove 17, and two fourth wrench heads 5 are respectively installed on both sides of the second slider 3, so that the second slider 3 is inserted into the second limiting groove 54. Then, the second screw 32 is installed in the second mounting hole 53 and screwed into the second threaded hole 31, thereby fixing the fourth wrench head 5 onto the second slider 3. If it is necessary to change to a different specification of opening, the third wrench head 4 can be slid, so that the first slider 2 slides into the first through hole 14. At this time, the first slider 2 loses its limiting position, so the third wrench head 4 can rotate. After rotating 180 degrees, slide the third wrench head 4 again to slide the first slider 2 into the first through groove 13, thus changing the opening. The first through groove 13 restricts the rotation of the first slider 2, allowing the rotational force applied by the wrench lever 1 to be transmitted to the bolt through the third wrench head 4. Similarly, the same method can be used to slide the second slider 3 into the second through hole 18, thereby adjusting the fourth wrench head 5. The first wrench head 11 is used to support the first opening 12, the second wrench head 15 is used to support the second opening 16, the third wrench head 4 is used to support the third opening 41 and the fourth opening 42, another third wrench head 4 is used to support the fifth opening 45 and the sixth opening 46, the fourth wrench head 5 is used to support the seventh opening 51 and the eighth opening 52, and another fourth wrench head 5 is used to support the ninth opening 55 and the tenth opening 56. This utility model provides ten different specifications of wrench openings from the first opening 12 to the tenth opening 56.
