Description

Technical Field

[0001] This utility model relates to the field of socket wrench technology, specifically to a socket wrench with adjustable inner diameter. Background Technology

[0002] Adjustable socket wrenches play a crucial role in many fields such as mechanical maintenance and assembly. Since the sizes of nuts and bolts that need to be disassembled or installed vary in different scenarios, adjustable socket wrenches can flexibly adapt to various specifications, meet diverse operational needs, and improve work efficiency.

[0003] Traditional adjustable-diameter wrenches typically use a rotating handle to drive an internal mechanism that causes the socket's jaws to contract or expand synchronously, thereby clamping and rotating nuts of different sizes. When using them, the user needs to first adjust the socket to the appropriate diameter, and then apply torque as if using a regular wrench to complete the operation.

[0004] However, existing adjustable socket wrenches still have certain limitations in use. Because the handle direction of traditional adjustable socket wrenches is fixed, it is difficult to adjust to the optimal force angle in complex working conditions such as narrow spaces or obstructed vision, making operation very laborious. Moreover, the handle length is not variable, which means that it is not possible to effectively extend the lever arm when high torque is required, and the overall length is not conducive to storage and carrying. Therefore, an adjustable socket wrench is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a socket wrench with an adjustable inner diameter. This effectively solves the problems of traditional adjustable socket wrenches, which have fixed handle directions, making it difficult to adjust to the optimal force angle in complex working conditions such as narrow spaces or obstructed vision, resulting in strenuous operation; and their handle length is fixed, making it impossible to effectively extend the lever arm when high torque is required, and their overall length is also unfavorable for storage and carrying.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] See attached document Figure 1-5 An adjustable inner diameter socket wrench, comprising:

[0028] The sleeve body 1, main block 2, and handle 3 are provided. The main block 2 is located on the top of the sleeve body 1, and the handle 3 is connected to the outside of the main block 2. The sleeve body 1 is composed of multiple radially movable jaws. These jaws adjust the inner diameter of the sleeve according to different fastener sizes to adapt to various fastener specifications. When it is necessary to adapt to fasteners of different sizes, the jaws change the inner diameter of the sleeve body 1 by radial movement. The force applied by the operator is transmitted through the handle 3, then through the main block 2 to the sleeve body 1, realizing the tightening or loosening of the fastener. The outer wall of the main block 2 is provided with a rotating component for adjusting the application position of the handle 3. This rotating component includes:

[0029] The movable groove 201 and the connecting ring 4 are provided. The movable groove 201 is opened on the outer wall of the main block 2. The inner wall of the connecting ring 4 is fixedly provided with a rotating ring 402, and the rotating ring 402 is movably engaged with the inner wall of the movable groove 201. The movable groove 201 provides a track for the movement of the rotating ring 402 and restricts its movement direction. In use, the rotating ring 402 can move and rotate along the inner cavity of the movable groove 201, so that the connecting ring 4 can be adjusted relative to the main block 2, thereby driving the subsequently connected handle 3 to change the application orientation.

[0030] The snap-fit ​​unit includes a fixing block 202 and multiple sets of snap-fit ​​blocks 403. The fixing block 202 is fixedly installed on the inner wall of the moving groove 201. Multiple sets of snap-fit ​​slots 203 are provided on the top of the fixing block 202. The multiple sets of snap-fit ​​blocks 403 are evenly fixed on the bottom of the rotating ring 402. The snap-fit ​​blocks 403 are connected and snap-fitted into the corresponding snap-fit ​​slots 203. In use, when the rotating ring 402 rotates to the appropriate position, the snap-fit ​​blocks 403 snap into the corresponding snap-fit ​​slots 203 to realize the positioning of the rotating ring 402 in the moving groove 201, thereby fixing the application position of the handle 3.

[0031] A connecting block 401 is fixedly welded to the outer wall of the connecting ring 4. A groove is provided on the outer wall of the connecting block 401, and a connecting plate 301 is rotatably connected to the inner wall of the groove via a pin. The connecting plate 301 is fixedly connected to the handle 3. The connecting plate 301 rotates in the groove of the connecting block 401 via the pin, thereby allowing the handle 3 to rotate at a certain angle relative to the connecting ring 4 to adapt to different usage scenarios.

[0032] The handle 3 has a cross groove 302 on its outer wall, and a cross rod 5 that slides along its length is movably inserted into the inner wall of the cross groove 302. A rod head 501 for applying force to operate the wrench is fixedly installed on the outer wall of the cross rod 5. The cross rod 5 slides along the cross groove 302 to change the lever arm length. When in use, the operator pulls the cross rod 5 as needed to make it slide in the cross groove 302, thereby adjusting the position of the rod head 501 and changing the lever arm length to meet different torque requirements.

[0033] A guide groove 305 is provided on the inner wall of the cross groove 302. A guide block 502 is movably engaged with the inner wall of the guide groove 305, and the guide block 502 is fixedly connected to the outer wall of the cross rod 5. The guide block 502 moves in the guide groove 305 to ensure that the cross rod 5 slides stably in the cross groove 302 and to prevent the cross rod 5 from moving excessively and detaching from the handle 3 during the sliding process.

[0034] The guide block 502 has a connecting groove 503 on its outer wall, and a limiting block 504 is movably inserted into the inner wall of the connecting groove 503. The handle 3 has a first limiting port 303 on its outer wall, and the limiting block 504 is mated and locked in the first limiting port 303. The handle 3 has a second limiting port 304 on its outer wall. The first limiting port 303 and the second limiting port 304 are distributed adjacent to each other and are arranged sequentially along the length of the handle 3.

[0035] When in use, when the cross bar 5 is retracted into the handle 3, the limiting block 504 moves to a position aligned with the first limiting port 303. The limiting block 504 is inserted into and locked in the first limiting port 303, thus restricting the cross bar 5 inside the handle 3. When the cross bar 5 is extended, the limiting block 504 moves to a position aligned with the second limiting port 304. The limiting block 504 is inserted into and locked in the second limiting port 304, thus fixing the application position of the cross bar 5 and promoting the stability of the application of the cross bar 5.

[0036] A spring strip 505 is fixedly installed on the inner wall of the connecting groove 503, and a push plate 506 is fixedly installed on the other end of the spring strip 505. The push plate 506 is fixedly installed on the outer wall of the limiting block 504. In its natural state, the spring strip 505 pushes the limiting block 504 to move outward toward the cross rod 5. In use, the elastic force of the spring strip 505 pushes the push plate 506, so that the limiting block 504 always has a tendency to move outward toward the cross rod 5. When the cross rod 5 slides to the appropriate position, the limiting block 504 engages in the corresponding position, thereby limiting and fixing the position of the cross rod 5.

[0037] Working principle:

[0038] When in use, the user holds the connecting block 401 and pulls it upward, causing the upward-moving connecting block 401 to move the connecting ring 4 upward. The upward-moving connecting ring 4 then moves the rotating ring 402 upward, causing the rotating ring 402 to move the locking block 403 upward, disengaging the locking block 403 from the locking slot 203. At this time, the connecting ring 4 is in a freely rotatable state. The user rotates the connecting block 401 horizontally, causing the rotating ring 402 to slide along the upper part of the inner cavity of the moving groove 201 of the main block 2, adjusting the handle 3 to the desired position to find the optimal force angle. This reduces the difficulty of applying force with traditional wrenches in narrow or obstructed working conditions. After adjustment, the user releases the connecting block 401. Under the action of gravity, the connecting ring 4 moves downward, causing the rotating ring 402 to move downward, causing the locking block 403 at its bottom to re-engage into the corresponding locking slot 203 on the fixed block 202, achieving a secure horizontal lock and ensuring that the handle 3 will not rotate accidentally during operation.

[0039] When increased torque is required, the user presses the limiting block 504 inward through the first limiting port 303, causing the limiting block 504 to disengage from the first limiting port 303. Then, by pulling the rod head 501 outward, the cross rod 5 slides along the cross groove 302 of the handle 3. After the cross rod 5 extends, the limiting block 504 moves to a position aligned with the second limiting port 304. The limiting block 504 automatically pops out under the push of the spring strip 505 and locks into the second limiting port 304 on the outer wall of the handle 3, firmly locking the cross rod 5 in the working state to prevent accidental movement from affecting the stability of use. After the operation is completed, the cross rod 5 is pushed back into the handle 3, shortening the overall length for easy carrying and storage.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
