Description

Technical Field

[0001] This utility model relates to the field of wrench tools, and in particular to a steerable and adjustable movable wrench. Background Technology

[0002] Currently, adjustable wrenches and open-end wrenches are commonly used for tightening, connecting, and disassembling bolts or nuts. There are two types of wrenches commonly used. One type is called an open-end wrench. Open-end wrenches often come with nuts of different sizes, requiring a wrench of the corresponding size to be used. This process is cumbersome and affects work efficiency. The other type is called an adjustable wrench. During use, the distance between the two openings is adjusted by slowly rotating the worm gear screw.

[0003] Some existing adjustable wrenches use a single-thread screw structure. When the screw rotates once, the distance the movable jaw moves is equal to the pitch. When adjusting the movable jaw, it is time-consuming and laborious, the adjustment is not smooth, the opening and closing range is small, and it is easy to loosen during use. In addition, existing adjustable wrenches rely on a worm gear screw in a square hole to adjust the opening and closing of the wrench. The wrench strength is relatively low and it is easy to break. Utility Model Content

[0004] The purpose of this invention is to provide a steerable and adjustable wrench to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a steerable adjustable wrench, comprising an adjustable wrench body, a fixed jaw, a movable jaw, a threaded screw, an internally threaded sleeve, a rack, a first gear, a second gear, and an arc-shaped column. The fixed jaw is connected to the left rear end of the adjustable wrench body, and the movable jaw is provided at the left front end of the adjustable wrench body. An installation groove is provided inside the adjustable wrench body, and the threaded screw is disposed inside the installation groove. An internally threaded sleeve is provided on the right side of the movable jaw, and the internally threaded sleeve is fitted onto the outside of the threaded screw. The internally threaded sleeve and the threaded screw are threadedly connected. The wrench body has a groove on the top rear side. The groove has slots on both the left and right sides and at both ends. A limit rod is connected between the front and rear sides of the groove. A rack is slidably connected to the outside of the limit rod. A push plate is connected to the top of the rack. Gear 1 is meshed with the lower end of the rack. Gear 1 is installed on the rear side of the groove. Gear 2 is meshed with the right side of Gear 1. Gear 2 is sleeved on the outside of the threaded screw. Circular grooves are opened on the upper ends of both sides of the rack. A spring is connected to the side of the circular groove facing the limit rod. An arc-shaped column is connected to the other end of the spring. The arc-shaped column matches the slot.

[0006] Preferably, the threaded screw is a four-threaded screw. When the threaded screw rotates, the internal threaded sleeve moves a distance four times the pitch of the threaded screw. The internal threaded sleeve can thus drive the movable jaw to move quickly, improving the flexibility of the movable jaw adjustment and facilitating the user to flexibly adjust the opening and closing degree between the movable jaw and the fixed jaw. Furthermore, the movable wrench body does not have a square hole, which improves the overall structural strength of the movable wrench body and ensures its service life. When it is necessary to fix the movable jaw, the user pushes the push plate to the rear. The push plate can drive the rack to move to the rear. When the arc-shaped column is locked in the rear slot by the spring rebound force, the rack meshes with gear one. The rack can then restrict the rotation of gear one, gear two, and the threaded screw, thereby restricting the movable jaw and preventing it from loosening during use.

[0007] Preferably, an adjustment knob is provided on the front side of the adjustable wrench body, and the adjustment knob is connected to the front end of the threaded screw.

[0008] Preferably, a mounting plate is provided on the rear side of the adjustable wrench body, and the rear end of the threaded screw is mounted on the front side of the mounting plate via a bearing.

[0009] Preferably, the left side of the adjustable wrench body has a through groove that communicates with the mounting groove.

[0010] Preferably, a connecting block is connected to the right side of the movable jaw, and the right end of the connecting block is connected to the left side of the internal threaded sleeve through a through groove.

[0011] Preferably, the outer side of the adjustable wrench body is provided with a reinforcing groove, and the reinforcing groove has two parts, one upper and one lower.

[0012] Preferably, a storage hole is provided at the bottom of the inner part of the upper reinforcing groove, and the storage hole is located on the right side of the inner part of the reinforcing groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a fixed jaw, a movable jaw, a threaded screw, an internal threaded sleeve, a rack, gear one, gear two, and an arc-shaped column, the threaded screw is a four-threaded rod. When the threaded screw rotates, the internal threaded sleeve moves a distance four times the pitch of the threaded screw. The internal threaded sleeve can thus drive the movable jaw to move quickly, improving the flexibility of the movable jaw adjustment and facilitating the personnel to flexibly adjust the opening and closing degree between the movable jaw and the fixed jaw. Moreover, the movable wrench body does not have a square hole, which improves the overall structural strength of the movable wrench body and ensures the service life of the movable wrench body. When it is necessary to fix the movable jaw, the personnel push the push plate to the rear, which can drive the rack to move to the rear. When the arc-shaped column is locked in the rear slot by the spring rebound force, the rack meshes with gear one. The rack can thus restrict the rotation of gear one, gear two, and the threaded screw, thereby restricting the movable jaw and preventing it from loosening during use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 The present invention provides a steerable adjustable wrench, comprising an adjustable wrench body 1, a fixed jaw 2, a movable jaw 3, a threaded screw 7, an internal threaded sleeve 10, a rack 16, a first gear 18, a second gear 19, and an arc-shaped column 22.

[0022] The adjustable wrench body 1 has a fixed jaw 2 connected to its left rear end, and a movable jaw 3 located at its left front end. An installation groove 4 is formed inside the adjustable wrench body 1, and a threaded screw 7 is installed inside the installation groove 4. An internal threaded sleeve 10 is located on the right side of the movable jaw 3, and the internal threaded sleeve 10 is fitted onto the outside of the threaded screw 7, with a threaded connection between the internal threaded sleeve 10 and the threaded screw 7. A sliding groove 13 is formed on the top rear side of the adjustable wrench body 1, and slots 14 are formed on both the left and right sides and at both ends of the sliding groove 13. A limiting rod 17 is connected between the front and rear sides of the inner side of the slide groove 13. A rack 16 is slidably connected to the outer side of the limiting rod 17. A push plate 15 is connected to the top of the rack 16. A gear 18 is meshed with the lower end of the rack 16. The gear 18 is installed on the rear side of the inner side of the slide groove 13. A gear 29 is meshed with the right side of the gear 18. The gear 29 is sleeved on the outer side of the threaded screw 7. Circular grooves 20 are opened on the upper ends of both sides of the rack 16. A spring 21 is connected to the side of the circular groove 20 facing the limiting rod 17. The other end of the spring 21 is connected to an arc-shaped post 22, which matches the slot 14. The threaded screw 7 is a four-threaded screw. When the threaded screw 7 rotates, the internal threaded sleeve 10 moves a distance four times the pitch of the threaded screw 7. The internal threaded sleeve 10 can thus drive the movable jaw 3 to move quickly, improving the flexibility of the movable jaw 3 adjustment. This makes it easier for personnel to flexibly adjust the opening and closing degree between the movable jaw 3 and the fixed jaw 2. Furthermore, the adjustable wrench body 1 does not have a square hole, which improves the overall structure of the adjustable wrench body 1. The strength ensures the service life of the adjustable wrench body 1. When it is necessary to fix the movable jaw 3, the operator pushes the push plate 15 to the rear. The push plate 15 can drive the rack 16 to move to the rear. When the arc-shaped column 22 is engaged in the rear slot 14 by the spring 21, the rack 16 meshes with the gear 18. The rack 16 can thus limit the rotation of the gear 18, the gear 2 19, and the threaded screw 7, thereby limiting the movable jaw 3 and preventing the movable jaw 3 from loosening during use.

[0023] Please see Figures 1-3 In this embodiment, an adjustment knob 6 is provided on the front side of the adjustable wrench body 1. The adjustment knob 6 is connected to the front end of the threaded screw 7. An mounting plate 8 is provided on the rear side of the adjustable wrench body 1. The rear end of the threaded screw 7 is mounted on the front side of the mounting plate 8 through a bearing. A through groove 5 is provided on the left side of the adjustable wrench body 1. The through groove 5 communicates with the mounting groove 4. A connecting block 9 is connected to the right side of the movable jaw 3. The right end of the connecting block 9 is connected to the left side of the internal threaded sleeve 10 through the through groove 5. The adjustment knob 6 facilitates the rotation of the threaded screw 7 by the operator. The mounting plate 8 facilitates the installation of the other end of the threaded screw 7. The through groove 5 facilitates the setting of the connecting block 9. The connecting block 9 can thus connect the movable jaw 3 and the internal threaded sleeve 10. When the operator rotates the adjustment knob 6, the adjustment knob 6 can drive the threaded screw 7 to rotate. The internal threaded sleeve 10 is driven by the thread of the threaded screw 7, thereby driving the movable jaw 3 to move through the connecting block 9.

[0024] Please see Figure 1 In this embodiment, a reinforcing groove 11 is provided on the outer side of the adjustable wrench body 1. The reinforcing groove 11 has two parts, one upper and one lower. A storage hole 12 is provided at the bottom of the inner part of the upper reinforcing groove 11. The storage hole 12 is located on the right side of the inner part of the reinforcing groove 11. The opening of the reinforcing groove 11 can strengthen the structural strength of the adjustable wrench body 1. The opening of the storage hole 12 facilitates the hanging and storage of the adjustable wrench body 1.

[0025] When adjusting the opening and closing degree between the fixed jaw 2 and the movable jaw 3, the rack 16 is first pushed to the front of the slide groove 13 by the push plate 15, so that the arc-shaped column 22 is engaged in the front groove 14. Then, the operator rotates the adjustment knob 6, which drives the threaded screw 7 to rotate. The internal threaded sleeve 10 is acted upon by the thread of the threaded screw 7, thereby driving the movable jaw 3 to move through the connecting block 9. The threaded screw 7 is a four-threaded rod. When the threaded screw 7 rotates, the internal threaded sleeve 10 moves a distance four times the pitch of the threaded screw 7. The internal threaded sleeve 10 can thus drive the movable jaw 3 to move quickly, improving the flexibility of the movable jaw 3 adjustment and facilitating its movement. The operator can flexibly adjust the opening and closing degree between the movable jaw 3 and the fixed jaw 2. Furthermore, the movable wrench body 1 does not have a square hole, which improves the overall structural strength of the movable wrench body 1 and ensures its service life. When the movable jaw 3 needs to be fixed, the operator pushes the push plate 15 to the rear. The push plate 15 can drive the rack 16 to move to the rear. When the arc-shaped column 22 is engaged in the rear slot 14 by the spring 21's rebound force, the rack 16 meshes with gear 18. The rack 16 can thus restrict the rotation of gear 18, gear 29, and the threaded screw 7, thereby restricting the movable jaw 3 and preventing it from loosening during use.

[0026] Through the above steps, by setting up a fixed jaw 2, a movable jaw 3, a threaded screw 7, and an internal threaded sleeve 10, the threaded screw 7 is a four-threaded rod. When the threaded screw 7 rotates, it can increase the range of movement of the internal threaded sleeve 10, thereby improving the flexibility of adjusting the opening and closing degree between the movable jaw 3 and the fixed jaw 2. Furthermore, the adjustable wrench body 1 does not have a square hole, which improves the overall structural strength of the adjustable wrench body 1 and ensures its service life. The arc-shaped column 22 limits the sliding of the rack 16. When rack 16 meshes with gear 18, it can restrict the movable jaw 3, preventing it from loosening during use. This addresses the problems of some existing adjustable wrenches that use a single-thread screw 7 structure, where the distance the movable jaw 3 moves is equal to the screw pitch when the screw rotates once. This makes it time-consuming and laborious for personnel to adjust the movable jaw 3, resulting in an uneven adjustment, a small opening and closing range, and a tendency to loosen during use. Furthermore, existing adjustable wrenches rely on a worm gear screw in a square hole to adjust the wrench's opening and closing, which results in relatively low wrench strength and a tendency to break.
