[0002] In industrial settings such as machinery assembly, automotive repair, and equipment maintenance, the assembly and disassembly of bolts and nuts is very common. However, traditional wrenches have significant limitations when faced with complex working conditions:

[0003] 1. Traditional wrenches have fixed-size structures with semi-open or fully enclosed heads. Every time a bolt or nut is tightened, the operator needs to frequently re-fit and tighten the wrench before tightening it. This process is cumbersome and reduces the efficiency of disassembly and assembly.

[0004] 2. The existing wrench head is designed to be adjustable, but each adjustment requires manual locking and then tightening, which is cumbersome.

[0005] 3. Existing wrench heads are designed with multiple gears in rigid mesh, but a side pressure block needs to be added to the side end. After each tightening, the head does not need to be removed from the bolt or nut. The side pressure block is manually released to disengage the gears. After resetting, the side pressure block is pressed down again for the next tightening operation. The structure is complex and the disassembly and assembly efficiency is low. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] To achieve the above objectives, this utility model provides a universal internal locking wrench, see reference. Figure 1-4 As shown, it includes a Y-shaped handle 1, a first swing ring 2, a second swing ring 3, an internal hexagonal cylinder 4, and a locking element 5. The front end of the Y-shaped handle 1 is provided with the first swing ring 2. The left and right sides of the first swing ring 2 are connected to the left and right sides of the Y-shaped handle 1 with movable pins. The second swing ring 3 is sleeved inside the first swing ring 2. The front and rear sides of the second swing ring 3 are connected to the front and rear sides of the first swing ring 2 with movable pins. The second swing ring 3 is equipped with a rotatable internal hexagonal cylinder 4. A locking element 5 is provided between the inner side of the second swing ring 3 and the side of the internal hexagonal cylinder 4 to abut against the rotation of the internal hexagonal cylinder 4.

[0025] In this embodiment, the left and right sides of the first swing ring 2 are connected to the left and right sides of the Y-shaped handle 1 via movable pins. These pins can be end-pins. The pins on both sides allow the first swing ring 2 to rotate 360 ​​degrees in the front-to-back direction. The front and back sides of the second swing ring 3 are connected to the front and back sides of the first swing ring 2 via movable pins. These pins are also end-pins. The pins on both sides allow the second swing ring 3 to rotate 360 ​​degrees in the left-to-right direction. The first swing ring 2 and the second swing ring 3 swing in the horizontal and vertical directions via the Y-shaped handle 1. Holding the Y-shaped handle 1 allows the internal hexagonal bevel to rotate. After the screw or bolt is inserted into the post 4, the Y-shaped handle 1 held by hand will automatically adjust its angle relative to the screw or bolt. That is, the first swing ring 2 and the second swing ring 3 swing at the corresponding angle. This solves the problem of the inappropriate usage process and inconvenience to the user, which is the traditional method of first adjusting the fixed wrench angle and then fitting it to tighten the screw. In addition, the locking part 5 engages with the internal hexagonal cylinder 4 to press against the rotation of the internal hexagonal cylinder 4. This structure is elastic and automatically presses against the cylinder. Each time, the wrench can be turned directly, which solves the problem of the traditional operation of pressing and turning at the same time. The use of the wrench becomes simple and easy.

[0026] Furthermore, the inner side of the second swing ring 3 is provided with an arc-shaped inner groove 6 that is deep in the middle and shallow at both ends. The second swing ring 3 is provided with a blind hole 7 at one end of the arc-shaped inner groove 6. The locking member 5 is located in the arc-shaped inner groove 6 and moves. A spring 8 is provided between one end of the locking member 5 and the blind hole 7. The side of the internal hexagonal cylinder 4 is provided with teeth 9. The end face of the locking member 5 is provided with locking teeth 10. The locking teeth 10 and the teeth 9 are meshed and connected. The locking member 5 is provided with an arc-shaped curved surface 11 on the side away from the locking teeth 10.

[0027] In this embodiment, the locking member 5 is slidably installed in the arc-shaped inner groove 6. Based on the structural design of the second swing ring 3, the arc-shaped inner groove 6 is a crescent-shaped structure that is deep in the middle and shallow at both ends. When the locking member 5 is located in the middle of the arc-shaped inner groove 6, the arc-shaped curved surface 11 is close to the inner wall of the arc-shaped inner groove 6, and the entire locking member 5 is contained in the arc-shaped inner groove 6, so that the locking teeth 10 are far away from the teeth 9. In this way, the locking member 5 is separated from the internal hexagonal cylinder 4 and fails to engage. The internal hexagonal cylinder 4 can rotate freely in the second swing ring 3. That is, the internal hexagonal cylinder 4 of the wrench does not need to be disengaged from the screw or bolt. The handle can be directly rotated in the opposite direction to reset it. The initial wrench position facilitates the next tightening action. When the wrench is turned clockwise, the internal hexagonal cylinder 4 rotates clockwise, causing the locking element 5 to slide along the arc-shaped inner groove 6, moving towards the shallower ends of the arc-shaped inner groove 6. As a result, the space for the arc-shaped curved surface 11 to move along the arc-shaped inner groove 6 becomes smaller and smaller, and the fit becomes tighter and tighter, so that the locking teeth 10 and teeth 9 mesh with each other. In this way, the locking element 5 is pressed against the internal hexagonal cylinder 4 and fixed in place. Thus, during the continued tightening of the wrench, the screw or bolt can be tightened or loosened. Each time, the wrench is turned directly, without the traditional pressing operation. The whole operation is very simple, and the angle is automatically adjusted.

[0028] Furthermore, the upper inner side of the second swing ring 3 is provided with a second annular groove 12, and the upper part of the internal hexagonal cylinder 4 is provided with a cylindrical annular groove 13. A limiting opening ring 14 is provided between the cylindrical annular groove 13 and the second annular groove 12, which facilitates the installation of the internal hexagonal cylinder 4 to prevent it from falling off, and also facilitates the replacement of the internal hexagonal cylinder 4. It is only necessary to retract the opening of the limiting opening ring 14 to disengage it, which is very convenient. Moreover, the internal hexagonal dimensions of the internal hexagonal cylinder 4 can be changed to the corresponding dimensions according to the work requirements.

[0029] Furthermore, the bottom of one side of the second swing ring 3 is integrally connected with a constricted step portion 15, and the bottom of the internal hexagonal cylinder 4 is provided with an outwardly protruding step position 16, which is inserted and stopped at the constricted step portion 15.

[0030] Furthermore, the hexagonal cylinder 4 has a magnet 17 at the bottom of the hexagonal socket, which makes it easy to remove the screw or bolt after screwing. The Y-shaped handle 1 has an hexagonal hole 18 at the rear end, which makes it easy to insert the hexagonal extension rod, making it easier to screw with less effort.

[0031] In summary, this utility model provides a universal internal locking wrench. By setting a locking element 5 that engages with the side of the internal hexagonal cylinder 4, the wrench can automatically lock against the internal hexagonal cylinder 4 when rotated, making it easy to tighten screws. The structure is simple and the operation is convenient. The Y-shaped handle 1 is provided with a first swing ring 2 and a second swing ring 3, which allows the first swing ring 2 to swing in the horizontal direction and the second swing ring 3 to swing in the vertical direction, making it convenient for the wrench head to automatically adjust the hand grip angle for operation, and improving the efficiency of screw disassembly and assembly.

[0032] The technical principles of this utility model have been described above with reference to specific embodiments, which are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. Those skilled in the art can conceive of other specific embodiments of this utility model without creative effort, and these embodiments will all fall within the protection scope of this utility model.
