Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustable wrench technology, specifically a new type of adjustable wrench that quickly and automatically locks and releases. Background Technology
[0002] Adjustable wrenches are among the most common tools. Existing traditional adjustable wrenches have the function of adjusting the jaw size, but the opening and closing of the jaws and the adjustment require first visually judging the size of the nut, initially adjusting the jaw size, then placing the wrench on the nut, and finally adjusting it to the correct position before use. This is laborious, time-consuming, and inefficient. Sometimes, if the initial adjustment is too small, it needs to be readjusted. It is difficult to quickly adapt to different sizes of bolts to be disassembled and achieve the effect of automatic tightening and loosening. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of adjustable wrench that can quickly and automatically tighten and loosen, solving the problems of laborious and time-consuming use and low efficiency of current adjustable wrenches.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a novel fast and automatic locking and releasing adjustable wrench, including a wrench body, a movable locking plate, a movable column, and a control rod. One end of the wrench body has an opening, and the end of the opening away from the opening direction is provided with a first movable groove. The movable locking plate is embedded in the first movable groove and can slide back and forth along the first movable groove without falling off. One end of the movable column is fixedly connected to the movable locking plate and is embedded in a second movable groove, and the other end is connected to a first spring and is subjected to its pressure. The movable locking plate is in contact with one end of the opening of the wrench body, and a toothed rack is embedded on the surface of the movable column.
[0005] Preferably, the second, third, fourth, and fifth movable slots are interconnected.
[0006] Preferably, the end of the movable plate away from the first movable slot extends beyond the opening (2) of the wrench body.
[0007] Preferably, the control rod in the fifth movable slot is movably connected to the wrench body through the third locking pin, and is on the same horizontal line as the wrench body under the action of the fourth spring.
[0008] Preferably, the end of the movable push block near the control rod is movably connected to one end of the connecting rod via a first locking pin, and the other end of the connecting rod is movably connected to the control rod via a second locking pin. The control rod, the connecting rod, and the movable push block form a linkage mechanism.
[0009] Preferably, the end of the movable push block near the opening has a bevel, and the angle of the bevel end of the movable locking block is consistent with that of the movable push block.
[0010] Preferably, when the control lever and the wrench body are on the same horizontal line, the inclined end of the movable push block does not contact the inclined end of the movable locking block. The movable locking block moves away from the rack under the action of the second and third springs and does not mesh with the rack of the movable column. By squeezing the first spring, the movable locking plate (4) can slide back and forth along the direction of the second movable groove.
[0011] Preferably, by rotating the handle of the control lever, the movable push block can be moved towards the opening side in the fourth movable slot, pushing the movable locking block to move towards the movable column along the third movable slot, and squeezing the second and third springs, so that the toothed end of the movable locking block and the rack of the movable column mesh with each other, thereby locking the movable column and preventing the movable locking plate from moving.
[0012] In summary, this utility model has the following beneficial effects: This invention involves contacting the bolt to be disassembled with one end of the movable clamping plate extending beyond the opening of the wrench body, and applying external force. This causes the movable clamping plate to drive the movable column to compress the first spring until the bolt is fully inserted into the opening and is precisely locked between the movable clamping plate and the opening of the wrench body. This allows for rapid adaptation to bolts of different sizes. When the handle is held and the wrench is rotated to disassemble or assemble the bolt, the interaction of the linkage mechanism composed of the control rod, connecting rod, and movable push block pushes the movable clamping block and the rack of the movable column to engage with each other, achieving the purpose of the movable clamping plate quickly and automatically locking the bolt to be disassembled. When the handle is released, the control rod quickly returns to its original position under the action of the fourth spring, and the movable clamping block separates from the rack of the movable column. The movable clamping plate can then move freely in the direction of the second movable groove by compressing the first spring, achieving the purpose of the movable clamping plate quickly and automatically releasing the bolt to be disassembled, thus improving disassembly and assembly efficiency.

[0014] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] Example: like Figure 1-2 The present invention discloses a novel fast-acting automatic locking and unlocking adjustable wrench, comprising a wrench body 1, an adjustable locking plate 4, an adjustable column 5, and a control lever 21. The wrench body 1 has an opening 2 at one end, and a first adjustable groove 3 is provided at the end of the opening 2 away from the opening direction. The adjustable locking plate 4 is embedded in the first adjustable groove 3 and can slide back and forth along the first adjustable groove 3 without falling off. One end of the adjustable column 5 is fixedly connected to the adjustable locking plate 4 and embedded in a second adjustable groove 7, while the other end is connected to a first spring 8 and subjected to its pressure. The adjustable locking plate 4 contacts one end of the opening 2 of the wrench body 1. A toothed rack 6 is embedded on the surface of the adjustable column 5.
[0016] Preferably, the second movable slot 7, the third movable slot 11, the fourth movable slot 14, and the fifth movable slot 19 are interconnected.
[0017] Preferably, the end of the movable plate 4 furthest from the first movable slot 3 extends beyond the opening 2 of the wrench body 1.
[0018] Preferably, the control rod 21 in the fifth movable slot 19 is movably connected to the wrench body 1 through the third locking pin 18, and is on the same horizontal line as the wrench body 1 under the action of the fourth spring 20.
[0019] Preferably, the end of the movable push block 13 near the control rod 21 is movably connected to one end of the connecting rod 16 via a first locking pin 15, and the other end of the connecting rod 16 is movably connected to the control rod 21 via a second locking pin 17. The control rod 21, the connecting rod 16, and the movable push block 13 form a linkage mechanism.
[0020] Preferably, the end of the movable push block 13 near the opening 2 has a bevel, and the angle of the bevel end of the movable latch block 10 is consistent with that of the movable push block 13.
[0021] Preferably, when the control lever 21 and the wrench body 1 are on the same horizontal line, the inclined end of the movable push block 13 does not contact the inclined end of the movable latch block 10. The movable latch block 10 moves away from the rack 6 under the action of the second spring 9 and the third spring 12, and does not engage with the rack 6 of the movable column 5. By squeezing the first spring 8, the movable latch plate 4 can slide back and forth along the direction of the second movable groove 7.
[0022] Preferably, by rotating the handle 22 of the control lever 21, the movable push block 13 can be moved towards the opening 2 side in the fourth movable slot 14, pushing the movable locking block 10 to move towards the movable column 5 along the third movable slot 11, and squeezing the second spring 9 and the third spring 12, so that the toothed end of the movable locking block 10 meshes with the rack 6 of the movable column 5, thereby locking the movable column 5 and preventing the movable locking plate 4 from moving.
[0023] This invention is implemented as follows: the end of the movable clamping plate 4 extending beyond the opening 2 of the wrench body 1 contacts the bolt 23 to be disassembled, and external force is applied, causing the movable clamping plate 4 to drive the movable column 5 to compress the first spring 8 until the bolt 23 to be disassembled is completely inserted into the opening 2 and is just locked between the movable clamping plate 4 and one side of the opening 2 of the wrench body 1. This allows for quick adaptation to bolts 23 of different sizes to be disassembled. When the handle 22 is held and the wrench is rotated to disassemble or assemble the bolt 23, the control rod 21 and the connecting rod 16 are used to control the bolt 23. The interaction of the linkage mechanism formed by the movable push blocks 13 pushes the movable locking block 10 and the rack 6 of the movable column 5 to mesh with each other, so as to realize the purpose of the movable locking plate 4 to quickly and automatically lock the bolt 23 to be removed. When the handle 22 is released, the control rod 21 quickly resets under the action of the fourth spring 20, the movable locking block 10 and the rack 6 of the movable column 5 separate, and the movable locking plate 4 can move freely in the direction of the second movable groove 7 by squeezing the first spring 8, so as to realize the purpose of the movable locking plate 4 to quickly and automatically release the bolt 23 to be removed, thereby improving the efficiency of disassembly and assembly.
