[0025] Preferably, four sleeve plugs 7 are provided, and the four sleeve plugs 7 are distributed in an array with the center point of the connecting rod 6 as the center of the circle, and the sockets of the four sleeve plugs 7 are of different sizes.

[0026] Specifically, such as Figure 1 and Figure 2Among them, four socket plugs 7 are arranged at the center of the connecting rod 6. Under the extrusion of the spring 11, the limit rod 9 will be inserted into the limit hole 12 to limit the movement of the connecting rod 6. Among them, the upper and lower socket plugs 7 are perpendicular to the handle sleeve rod 1, while the front and rear socket plugs 7 are parallel to the handle sleeve rod 1. When operating the wrench, the downward socket plug 7 can operate on the bolt on the plane, while the forward socket plug 7 can operate on the bolt in the hole, such as the bolt on the car tire.

[0027] Preferably, the upper and lower ends of the spring 11 are respectively connected to the inner wall of the mounting bracket 8 and the surface of the pressure plate 10. The lower end of the limit rod 9 can be inserted into the limit hole 12. There are four limit holes 12, and the four limit holes 12 are arranged in an array with the center point of the connecting rod 6 as the center of the circle.

[0028] Specifically, the positions of the four limit holes 12 correspond to the positions of the four socket plugs 7. Pull the limit rod 9 upward, and the pressure plate 10 will move accordingly. The pressure plate 10 will squeeze the spring 11, and then the limit rod 9 will leave the limit hole 12, and then the connecting rod 6 can be rotated to adjust the position of the socket plug 7.

[0029] Preferably, threaded holes are formed on the surfaces of the telescopic plate 2 and the mounting block 4, and fasteners 18 are threadedly installed on the inner walls of the threaded holes.

[0030] Specifically, the mounting block 4 is inserted into the mounting groove and then fixed by the fastener 18, which is convenient for replacing the wrench head.

[0031] Working principle: When in use, the limit rod 9 will be inserted into the limit hole 12 to limit the position of the socket plug 7. When it is necessary to adjust the corresponding socket plug 7, pull the handle upward, driving the limit rod 9 to move upward. The limit rod 9 drives the pressure plate 10 to move upward. The pressure plate 10 will squeeze the spring 11, and then manually rotate the connecting rod 6 to adjust the position of the socket plug 7. When the bolt head to be operated protrudes on the plane, adjust the socket plug 7 of the corresponding size to the lower part of the wrench. When the bolt to be operated is recessed in the hole, adjust the socket plug 7 of the corresponding size to the front. After adjustment, release the limit rod 9, and under the action of the spring 11, the limit rod 9 is inserted into the limit hole 12 to limit the adjusted socket plug 7, so as to achieve the adjustment according to bolts of different sizes, adapt to the disassembly and installation of different bolts, improve the practicability of the socket wrench, and at the same time, the structure is simple and practical, which can reduce the production cost and is not easy to be damaged.

A threaded rod 15 is threadedly installed on the inner wall of the threaded cylinder 14. The front end of the threaded rod 15 is movably connected to the rear end of the telescopic plate 2.

[0034] Specifically, as Figure 1 and Figure 3 , the fixed plate 13 and the threaded cylinder 14 are arranged inside the handle sleeve rod 1, and a groove is opened on the upper surface of the rear end of the handle sleeve rod 1. There is a turning handle at the rear end of the threaded rod 15, which can facilitate the rotation of the threaded rod 15.

[0035] Preferably, a sliding rod 16 is fixedly installed at the rear part of the telescopic plate 2, and the outer side of the sliding rod 16 is slidably connected to the outer surface of the fixed plate 13.

[0036] Specifically, four sliding rods 16 are arranged, respectively at the four corners of the telescopic plate 2, which can make the telescopic plate 2 move stably.

[0037] Preferably, sliding plates 17 are fixedly installed on both sides of the telescopic plate 2, and the sliding plates 17 are slidably connected to the inner wall of the handle sleeve rod 1.

[0038] Working principle: Rotate the threaded rod 15. Since the threaded cylinder 14 is fixed, the threaded rod 15 will move into the handle sleeve rod 1, and the threaded rod 15 will push the telescopic plate 2 to move forward. At the same time, the sliding rod 16 and the sliding plates 17 also move, ensuring the stable movement of the telescopic plate 2, so as to achieve the adjustment of the length of the handle of the socket wrench according to needs, which is convenient for the staff to use.
