Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wrenches, and particularly to a fixing structure for replacing the size of the end of a wrench. Background Art
[0002] When a wrench is used for different nuts, it needs to be adjusted to fit the size. It usually includes a handle, with a fixed jaw and a movable jaw arranged on the handle, and the distance between the movable jaw and the fixed jaw is adjusted by an opening adjusting nut to adapt to nuts of different sizes.
[0003] When the end of the wrench faces nuts of different sizes, it needs to be adjusted. However, conventional wrenches cannot be accurately adjusted to the required size. Sometimes, it is necessary to adjust the wrench or make multiple adjustments, and it is impossible to accurately locate the corresponding size for use. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a fixing structure for replacing the size of the end of a wrench to facilitate accurate adjustment for nuts of specific sizes.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A fixing structure for replacing the size of the end of a wrench includes a handle. A U-shaped groove is provided at the front end of the handle. A through groove is provided on the inner wall of the U-shaped groove. A spring is provided at the bottom of the through groove. A sliding column is arranged in the through groove and abuts against the spring. Multiple jaws with different sizes are arranged in the U-shaped groove at the front end of the handle. Perforations are provided on both sides of the jaws, and the sliding column passes through the perforations to fix the jaws.
[0006] It is further set that: Sliding grooves are provided on the inner side walls of the jaws, and limiting pieces covering the perforations are arranged on the sliding grooves.
[0007] It is further set that: Strip-shaped grooves are provided on the inner walls of adjacent jaws located below, and embedding strips embedded in the grooves are provided at the bottoms of adjacent jaws located above.
[0008] It is further set that: Right-angle bodies are integrally provided on both sides of the front end of the handle.
[0009] In summary, the utility model has the following beneficial effects: Through the sliding columns on both sides, wrenches of different sizes can be clamped, and then, in the case of specific requirements, it can be accurate to the size of specific nuts, effectively ensuring the accuracy of adjustment. Brief Description of the Drawings

[0011] Figure 2 It is a schematic diagram of the jaws.
[0012] In the figure: 1. Grip; 2. U-shaped groove; 3. Through groove; 4. Spring; 5. Sliding column; 6. Jaw; 7. Perforation; 8. Slide groove; 9. Limiting piece; 10. Strip-shaped groove; 11. Embedding strip; 12. Right-angle body. Detailed implementation mode
[0013] The following further elaborates on the present utility model in conjunction with the attached drawings.
[0014] The fixed structure for replacing the wrench end size includes a grip 1. On both sides of the front end of the grip 1, integral right-angle bodies 12 are provided. Between the right-angle bodies 12 is a U-shaped groove 2. An inward through groove 3 is provided on the inner wall of the groove. A spring 4 is provided at the bottom of the through groove 3. A sliding column 5 is arranged in the through groove 3. The inner end of the sliding column 5 abuts against the spring 4, so that it can push the sliding column 5 outward.
[0015] In the groove, a plurality of U-shaped jaws 6 with different sizes are provided. Perforations 7 are provided on both sides of the jaws 6. The sliding column 5 pushed out by the spring 4 passes through the perforations 7 to realize the fixation of the jaws 6.
[0016] Slide grooves 8 are provided on the inner sides of the jaws 6. Limiting pieces 9 are slidably arranged in the slide grooves 8. The limiting pieces 9 are used to cover the perforations 7. So when the innermost jaw 6 is installed, it can abut against the sliding column 5 to prevent the sliding column 5 from moving inward continuously and avoid affecting the nut-tightening.
[0017] On adjacent jaws 6, a strip-shaped groove 10 is provided on the inner wall of the lower jaw 6, and an embedding strip 11 is provided at the bottom of the upper jaw 6. The embedding strip 11 can be embedded in the strip-shaped groove 10, so as to ensure the stability when a plurality of jaws 6 are stacked on each other. Among them, a strip-shaped groove 10 is provided at the bottom of the U-shaped groove 2 to ensure the stability of a jaw 6 fitting in the U-shaped groove 2.
[0018] Integral right-angle bodies 12 are provided on both sides of the front end of the grip 1, which can facilitate the stability after the jaws 6 are installed.
[0019] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make modifications without creative contributions to this embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
