It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] See also Figure 1-5The present invention provides a technical solution: a socket wrench head, comprising a connecting rod 1, one end of which is fixedly mounted a mounting bracket 2. The mounting bracket 2 is made of austenitic stainless steel and has a U-shaped structure. A rotating rod 3 is provided on the top surface of the mounting bracket 2. A mounting rod 4 is fixedly mounted on one end of the rotating rod 3. A sleeve A5 and a sleeve B6 are fixedly mounted on each end of the mounting rod 4. Both sleeves A5 and B6 have hexagonal bayonet holes 7 formed on their surfaces. Sleeves A5 and B6 can be mounted by welding or bolting. Welding ensures a secure connection, while bolting facilitates disassembly and replacement. A disc 8 is fixedly mounted on the top of the rotating rod 3. A rod 9 is provided through the surface of the disc 8, which is slidably connected to the rod 9. A pull block 10 is fixedly mounted on one end of the rod 9. A tension spring 11 is sleeved on the surface of the rod 9. One end of the tension spring 11 is fixedly connected to the pull block 10, and the other end of the tension spring 11 is fixedly connected to the disc 8. The top surface of the mounting frame 2 is provided with four groups of positioning holes 12, which are arranged in a circular pattern on the surface of the mounting frame 2. The tension spring 11 can be made of spring steel, which has good elasticity and durability, ensuring that it can maintain stable tension even during frequent use.

[0026] See also Figure 1-5 The nuts can be engaged and screwed by means of the provided sleeves A5, B6, and hexagonal bayonet 7. Sleeves A5 and B6 are provided with hexagonal bayonet 7 of different sizes, so that sleeves A5 and B6 can respectively screw nuts of different sizes. By default, sleeve A5 is extended for operation. When it is necessary to switch to sleeve B6 to screw a nut of another size, the operator only needs to pull the pull block 10 upwards. The pull block 10 then drives the insertion rod 9 to move until the insertion rod 9 leaves the positioning hole 12. This releases the limit of the mounting rod 4, and the mounting rod 4 can then be rotated. The mounting rod 4 is then rotated by the rotating rod 3. After rotating 180 degrees, the pull block 10 is released. Then, due to the tension of the tension spring 11, the tension spring 11 pulls the pull block 10 to move. The pull block 10 then drives the insertion rod 9 to insert into the positioning hole 12, at which point the mounting rod 4 is limited, and the operator can then switch to sleeve B6 for operation. At the same time, it is also possible to rotate only ninety degrees, so that the sleeve A5 and the sleeve B6 can be perpendicular to the connecting rod 1, which makes it easier to pry the nuts and reduces the difficulty of tightening some difficult nuts.

[0027] Example 2

[0028] See also Figure 4-5The mounting rod 4 is provided with a dirt ejection mechanism, which includes an inner groove 13. The inner groove 13 is provided inside the mounting rod 4. A chute 14 is provided on the inner wall of the inner groove 13. A slider 15 is slidably connected to the inner wall of the chute 14. A slide plate 16 is fixedly mounted on one end of the slider 15. A push plate 17 is fixedly mounted on one end of the slide plate 16. A push handle 18 is fixedly mounted on the surface of the slider 15. The push handle 18 is made of austenitic stainless steel. The push plate 17 is adapted to the size and shape of the hexagonal bayonet 7 and is made of ferritic stainless steel. The connection between the chute 14 and the slider 15 can adopt a guide rail or a ball bearing sliding method. The guide rail can provide smooth sliding, while the ball bearing sliding can reduce friction and improve sliding efficiency. The push handle 18 can then drive the slide plate 16 to move, and the slide plate 16 then slides through the slider 15, and at the same time, the slide plate 16 drives the push plate 17 to move until the push plate 17 is pushed out of the hexagonal slot 7. At this time, the push plate 17 can push out the stains, thereby removing the impurities or foreign objects that have entered the hexagonal slot 7. The push handle 18 is made of austenitic stainless steel, ensuring its durability and stability under frequent use.

[0029] Working principle: The nut can be engaged and screwed by the provided sleeve A5, sleeve B6 and hexagonal bayonet 7. At the same time, the sleeve B6 on the sleeve A5 is provided with hexagonal bayonet 7 of different sizes, so that the sleeve A5 and the sleeve B6 can respectively screw nuts of different sizes. By default, the sleeve A5 is extended outside for work, and when it is necessary to switch to the sleeve B6 to screw a nut of another size, the staff only needs to pull the pull block 10 upwards, and the pull block 10 can then drive the insertion rod 9 to move until the insertion rod 9 leaves the positioning hole 12, and then the limit of the installation rod 4 can be released, and then the installation rod 4 can be rotated, and the installation rod 4 is rotated by the rotating rod 3. After rotating one hundred and eighty degrees, the pull block 10 is released, and then due to The tension of the tension spring 11 causes the tension spring 11 to pull the pulling block 10 to move, and the pulling block 10 then drives the insertion rod 9 to insert into the positioning hole 12. At this time, the installation rod 4 can be limited. At this time, the sleeve B6 can be switched to work, and it can also be rotated only ninety degrees, so that the sleeve A5 and the sleeve B6 can be perpendicular to the connecting rod 1, which can facilitate the bending operation. For some difficult-to-tighten nuts, the difficulty of twisting can be reduced. The utility model can be suitable for nuts of different sizes respectively through the design of the sleeve A5 and the sleeve B6, thereby improving the versatility and applicability of the tool. At the same time, the mechanical structure design of the pulling block 10, the insertion rod 9 and the installation rod 4 is introduced, so that the staff can quickly switch and adjust the tool through simple operation. Working state, improves the convenience and efficiency of operation, and when it is necessary to bend the operation or to tighten the nut that is difficult to tighten, by rotating the sleeve A5 and the sleeve B6 perpendicular to the connecting rod 1, a better working angle and force transmission can be provided, thereby reducing the difficulty of handling complex tasks, and by quickly switching sleeves of different sizes and optimizing the working angle, the conversion time at work can be reduced, and more effective force transmission is provided when tightening the nut, thereby improving the overall work efficiency, and when impurities or foreign objects enter the hexagonal bayonet 7, the staff only needs to push the push handle 18, and the push handle 18 can then drive the slide plate 16 to move, and the slide plate 16 then slides through the slider 15, and the slide plate 16 drives the push plate 17 to move until the push plate 17 is released. The tool is pushed out of the hexagonal bayonet 7, and the stains can be pushed out by the push plate 17 at this time, thereby removing the impurities or foreign objects that have entered the hexagonal bayonet 7. The utility model introduces the mechanical structure design of the push handle 18, the slide plate 16 and the push plate 17, so that the staff can remove the impurities or foreign objects in the hexagonal bayonet 7 through simple operations, which greatly improves the convenience of cleaning and maintenance of the tool. Through the design of the mechanical device, the staff can safely remove stains or foreign objects without touching the bayonet, reducing the risk of accidental injury and improving the safety of operation. At the same time, regularly cleaning the impurities or foreign objects in the hexagonal bayonet 7 can effectively extend the service life of the tool and prevent foreign objects from affecting the normal use of the bayonet or damaging the tool.
