[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Depend on Figures 1 to 8 As shown, some embodiments of this utility model relate to a universal socket wrench, including a handle 2 for mounting a universal socket body 1, a connecting box 3 fixedly mounted on one end of the handle 2, a handle 4 passing through the connecting box 3, and a limiting component for locking the handle 4 on the connecting box 3.

[0031] An extension rod 5 is slidably installed inside the handle 4, and the extension rod 5 can extend or retract from the left and right ends of the handle 4.

[0032] In these embodiments, the universal socket body 1 is detachably mounted via the handle 2 for easy replacement. The handle 2, connecting box 3, and handle 4 together form the handle portion of the universal socket wrench. The handle 4 can stably pass through the connecting box 3 according to usage requirements, adjusting its length at both ends of the connecting box 3. A limiting component fixes the handle 4 to the connecting box 3, allowing for quick and stable adjustment of the handle 4's length. This effectively avoids the inconvenience caused by handles being too long or too short, enabling quick and stable turning of the handle 4 even in confined spaces, thus smoothly completing the operation of the universal socket wrench. This effectively reduces the difficulty of use, increases flexibility and adaptability, and better meets the needs of different environments. Furthermore, through the cooperation of the extension rod 5 and the handle 4, the extension rod 5 extends out of the handle 4 when needed, further extending the operating length of the handle 4. This makes the turning operation simpler and less strenuous, not only improving the flexibility of use but also reducing the difficulty of operation, better addressing different turning needs, and greatly improving the practicality of use.

[0033] In some implementations of universal socket wrenches, through holes 6 are provided on both the left and right sides of the connecting box 3, and the handle 4 slides through the through holes 6.

[0034] In these embodiments, the handle 4 can move quickly and stably in the connecting box 3 through the cooperation of the through hole 6 and the handle 4, and it is more convenient to adjust the length of the handle 4 at both ends of the connecting box 3. Preferably, the outer ring surface of the handle 4 and the through hole 6 can be an interference fit to ensure the stability of operation.

[0035] In some embodiments of the universal socket wrench, the limiting component includes a locking rod 7, and a limiting groove 8 communicating with the through hole 6 is provided in the connecting box 3. The locking rod 7 is slidably installed in the limiting groove 8. The locking rod 7 is used to limit the handle 4 on the connecting box 3. The connecting box 3 is provided with an adjustment component for engaging or disengaging the locking rod 7 from the handle 4.

[0036] In these embodiments, the cooperation between the through hole 6 and the limiting groove 8 ensures that the locking rod 7 can stably and accurately engage with the handle rod 4. The locking rod 7 is moved in the limiting groove 8 by the adjusting component, so that the locking rod 7 can reliably engage or disengage from the handle rod 4, thereby locking or unlocking the handle rod 4 in the connecting box 3. The operation is more convenient and efficient, and it is easy to adjust the length configuration of the handle rod 4 in a timely manner during use.

[0037] In some embodiments of the universal socket wrench, the upper and lower sidewalls of the limiting groove 8 are both formed with sliding grooves 9, and the upper and lower ends of the locking rod 7 are both formed with sliders 10, which are slidably installed in the corresponding sliding grooves 9.

[0038] In these embodiments, the cooperation between the slide groove 9 and the slider 10 helps to improve the stability of the locking rod 7 moving in the limiting groove 8, and also helps to improve the reliability of the locking rod 7 locking.

[0039] In some embodiments of the universal socket wrench, a plurality of evenly distributed locking grooves 11 are formed on the outer surface of the handle 4, and a locking head 12 is formed at one end of the locking rod 7, which can be engaged in the locking groove 11.

[0040] In these embodiments, the lock head 12 can be an arc-shaped protrusion, which, together with the arc-shaped groove 11, securely engages the lock rod 7 with the handle rod 4. This helps to improve the stability of the lock rod 7 in fixing the handle rod 4, and the multiple lock grooves 11 can also improve the anti-slip effect of the handle rod 4, making it easier to operate and use.

[0041] In some embodiments of universal socket wrench, the adjusting assembly includes two guide springs 13 and a positioning rod 14. One end of the two guide springs 13 is fixedly installed on the outer surface of the upper and lower ends of the locking rod 7, respectively. The connecting box 3 has two guide grooves 15 that communicate with the limiting groove 8. The guide springs 13 are fixedly installed in the corresponding guide grooves 15. A guide rod 16 is sleeved inside the guide springs 13. One end of the guide rod 16 is fixedly installed on the locking rod 7.

[0042] The outer surface of the connecting box 3 is provided with a positioning hole 17 that communicates with the limiting groove 8. The positioning rod 14 is threaded in the positioning hole 17. One end of the positioning rod 14 slides against the locking rod 7, and the other end of the positioning rod 14 forms a rotating wheel 18.

[0043] In these embodiments, one end of the guide spring 13 is fixed to the lock head 12 of the lock rod 7, and the other end is fixed in the guide groove 15, which can stably provide spring force. Then, in conjunction with the guide rod 16 inside the guide spring 13, the stability of the guide spring 13 is ensured. One end of the guide rod 16 is fixed to the lock head 12, and the other end is suspended inside the guide spring 13, which ensures that the guide rod 16 moves stably inside the guide spring 13. Rotating the wheel 18 causes the positioning rod 14 to extend into the positioning hole 17, thereby pushing the locking rod 7 along the limiting groove 8 towards the locking groove 11 of the handle rod 4, so that the lock head 12 is engaged in the locking groove 11. At the same time, the locking rod 7 compresses the guide spring 13 to lock the handle rod 4. When the wheel 18 is rotated in the opposite direction, the positioning rod 14 extends out of the positioning hole 17. Under the action of the elastic force of the guide spring 13, the guide spring 13 pushes the locking rod 7 out of the locking groove 11, thereby releasing the locking of the handle rod 4. This allows for the adjustment of the length of the handle rod 4, enabling flexible and timely adjustment of the handle rod 4 for easy turning operation. The adjustment operation is simpler and more convenient, which helps to reduce the difficulty of use.

[0044] In some embodiments of the universal socket wrench, the inner walls of both ends of the handle 4 are formed with tapered openings 19, and both ends of the extension rod 5 can pass through the corresponding tapered openings 19. A limiting boss 20 is formed in the middle of the extension rod 5, and both ends of the limiting boss 20 can fit into the corresponding tapered openings 19.

[0045] In these embodiments, the outlet of the conical opening 19 is adapted to the outer diameter of the handle 4, ensuring that the extension rod 5 can flexibly extend into or out of the handle 4. Both ends of the limiting boss 20 are formed with frustum surfaces adapted to the conical opening 19, so that the limiting boss 20 can fit tightly inside the conical opening 19, thereby realizing that the extension rod 5 is fixed on the conical opening 19 by the limiting boss 20. Through the cooperation of the limiting boss 20 and the conical opening 19, the extension rod 5 is guaranteed to extend and retract smoothly, effectively improving the stability of use.

[0046] In some embodiments of the universal socket wrench, the outer surfaces of both ends of the extension rod 5 can be detachably fitted with fixing heads 21, which are attached to the tapered opening 19.

[0047] In these embodiments, the fixing head 21 is threaded onto both ends of the extension rod 5, ensuring that the extension rod 5 is firmly fixed inside the handle 4. When in use, the fixing head 21 can be unscrewed to flexibly extend the extension rod 5, making it more convenient and reliable to use.

[0048] In some embodiments of the universal socket wrench, the handle 2 includes a support rod 22 and a movable rod 23. One end of the movable rod 23 is inserted into the support rod 22, and the other end of the movable rod 23 is detachably mounted with the universal socket body 1. The support rod 22 is provided with a mounting assembly for fixing the movable rod 23.

[0049] In these embodiments, the working length of the handle 2 can be flexibly adjusted through the cooperation of the support rod 22 and the movable rod 23, further improving the flexibility of use. With the cooperation of the mounting components, the length adjustment of the handle 2 can be completed in a timely and stable manner, making it more flexible to use. It should be understood that the universal socket body 1 can be threaded onto one end of the movable rod 23 to facilitate the replacement and adjustment of different universal socket bodies 1. The mechanical structure and working principle of the universal socket body 1 are existing technologies, so they will not be described in detail here. The main purpose of this utility model is to improve the handle part of the universal socket wrench. That is to say, the movable rod 23 of this utility model is adapted to install various universal socket bodies 1 in the prior art, and its specific structure is not limited in this article.

[0050] In some embodiments of the universal socket wrench, the mounting assembly includes a pin 24, a fixing hole 25 is formed on the support rod 22, and a plurality of evenly distributed insertion holes 26 are passed through the movable rod 23, with the pin 24 passing through the fixing hole 25 and the insertion holes 26.

[0051] A connecting ring 27 is rotatably mounted on one end of the pin 24. A connecting band 28 is fixedly connected to the connecting ring 27. A nut 29 is fixedly connected to one end of the connecting band 28. The nut 29 is threaded onto one end of the pin 24.

[0052] In these embodiments, after the movable rod 23 is inserted into the support rod 22 through the cooperation of the fixing hole 25, the insertion hole 26 and the pin 24, the fixing hole 25 and the corresponding insertion hole 26 are aligned, and then the pin 24 is inserted through the fixing hole 25 and the nut 29 is tightened on the pin 24. This can securely fix the movable rod 23 to the support rod 22 to adjust different usage lengths. Furthermore, through the cooperation of the connecting ring 27, the connecting strap 28 and the nut 29, it is easier and more convenient to install and remove the pin 24. The connecting ring 27 is rotated and installed in the groove on the pin 24, ensuring that the nut 29 can be quickly installed on the pin 24, thereby quickly completing the fixed installation of the movable rod 23.

[0053] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
