Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to a ratchet-equipped quick-release large-opening pliers wrench. Background Technology

[0002] In industries such as machinery manufacturing, construction, and power, it is often necessary to tighten or loosen large bolts, nuts, or other pipe fittings. Traditional wrenches have limited opening sizes, making it difficult to meet the clamping requirements of large workpieces. However, wide-opening pliers can open a larger diameter to accommodate large workpieces of different specifications, improving the efficiency of installation and maintenance of large equipment in industrial production.

[0003] Currently, a type of ratchet-equipped quick-release large-opening pliers wrench typically consists of seven parts: a fixed pliers body, a movable pliers body, a jaw, a pivot pin, a pin cover, a leaf spring, and a Phillips head screw. During use, the pivot pin needs to be pressed frequently to disengage and clamp the workpiece. This manual adjustment method is slow, inefficient, and cumbersome. Furthermore, the need to frequently press the pivot pin to adjust the opening is tedious and slow. Since the thickness and size of objects vary, each adjustment may not reach the appropriate clamping position, making it difficult to achieve a tight clamping in one go. It also features a straight, arc-shaped toothed design with a small opening, resulting in noticeable meshing noise and impact. The limited clamping size and opening restrict the size of the objects that can be clamped. The straight toothed grooves also contribute to a poor feel when moving the clamped object. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technology where frequent pressing of the pivot pin is required to disengage the workpiece and clamp it. The manual adjustment method is slow, inefficient, and cumbersome. In addition, the opening amount needs to be adjusted by frequently pressing the pivot pin, which is tedious and slow. Since the thickness and size of the objects are different, each adjustment may not be able to adjust to the appropriate clamping position, making it difficult to achieve a one-time clamping. The existing technology uses a straight arc-shaped toothed design with a small opening, resulting in a noticeable impact sound during meshing. The clamping size range is small, and the opening amount is small, which limits the size of the objects to be clamped. The toothed groove is straight, which makes the hand feel unpleasant when the object is being clamped. Therefore, this invention proposes a ratchet-type quick-release large-opening pliers wrench.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ratchet-type quick-release large-opening pliers wrench, comprising a fixed pliers body, an arc-shaped groove on the side end of the fixed pliers body, a ratchet pin slidably connected within the arc-shaped groove, a movable handle rotatably connected to the end of the ratchet pin away from the fixed pliers body, a ratchet body rotatably connected to the outer wall of the ratchet pin, a ratchet tooth matching the arc-shaped groove on one end of the ratchet body, an unlocking pin fixed to the side of the movable handle facing the arc-shaped groove on one side of the ratchet body, a compression spring fixed to the inner side of one end of the ratchet body, one end of the compression spring penetrating the ratchet body and fixed to the fixed pliers body, and the other end of the compression spring penetrating the ratchet body and abutting against the inner wall of the arc-shaped groove.

[0006] Preferably, a groove is provided on one side of the arc-shaped groove tooth in the fixing clamp body, and one end of the ratchet tooth abuts against the arc-shaped groove tooth.

[0007] Preferably, the angle of the groove is parallel to the angle of the arc-shaped groove teeth.

[0008] Preferably, the outer side of the fixing clamp body is provided with a plate opening, and both ends of the inner wall of the plate opening are fixed with bosses, which slide in the groove.

[0009] Preferably, one end of the ratchet pin is fixed to the plate opening.

[0010] Preferably, the object is held between the fixing clamp and the plate opening.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, by grasping the fixed handle on the fixed clamp body and pulling the movable handle upwards, the ratchet body rotates around the ratchet pin as the center, causing the ratchet teeth to rotate and apply force to the compression spring. This separates the ratchet teeth from the arc-shaped grooves of the fixed clamp body, allowing the plate protrusion to move quickly along the grooves on both sides of the fixed clamp body. When clamping, by grasping the fixed clamp body and pulling the movable handle upwards, the ratchet teeth disengage from the arc-shaped grooves of the fixed clamp body. Then, by moving the movable handle backwards, the plate protrusion moves backwards along the double grooves on the fixed clamp body. The object is placed between the fixed clamp body and the plate protrusion. Pushing the movable handle forward moves the plate protrusion upwards to the object, engaging with the fixed clamp body to quickly clamp the object. This device utilizes the arc-shaped grooves within the fixed clamp body... With a single-sided tooth design, the structure has been changed from an overall double-sided straight tooth groove to an overall single-sided arc tooth groove, making opening and closing smoother and more convenient. This allows for quick size adjustment and has a wide range of applications, suitable for water and electricity installations, industrial and mining enterprises. Compared with similar tools, the improved design eliminates the need for frequent pressing of the pivot pin, allowing for quick movement to the desired size simply by pulling it open by hand. It also provides a better grip when clamping objects. Traditional straight arc tooth quick-release pliers have a small opening and limited clamping range. This device designs the tooth groove of the fixed pliers body as an arc tooth groove, which increases the clamping range and makes it more widely applicable. It allows for more convenient and quick clamping of objects. The improved arc tooth shape increases the opening and reduces the impact of meshing noise. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1-5 As shown, this utility model provides a ratchet-type quick-release large-opening pliers wrench, including a fixed pliers body 1. The side end of the fixed pliers body 1 is provided with an arc-shaped groove 10. A ratchet pin 5 is slidably connected inside the arc-shaped groove 10. The end of the ratchet pin 5 away from the fixed pliers body 1 is rotatably connected to a movable handle 2. A ratchet body 6 is rotatably connected to the outer wall of the ratchet pin 5. One end of the ratchet body 6 is provided with a ratchet tooth 11 that matches the arc-shaped groove 10. The end of the movable handle 2 facing the arc-shaped groove 10 is fixed to one side of the ratchet body 6 with an unlocking pin 4. A compression spring 7 is fixed to the inner side of one end of the ratchet body 6. The other end of the compression spring 7 passes through the ratchet body 6 and abuts against the inner wall of the arc-shaped groove 10.

[0022] The effect achieved by the entire embodiment 1 is as follows: by grasping the fixed handle on the fixed clamp body 1 and pulling the movable handle 2 upward, the unlocking pin 4 rotates around the ratchet pin 5, causing the ratchet body 6 to rotate and apply force to the compression spring 7, so that the ratchet teeth 11 separate from the arc-shaped groove teeth 10 of the fixed clamp body 1, realizing the rapid movement of the plate opening 3 protrusion 8 along the grooves 9 on both sides of the fixed clamp body 1. In this device, the arc-shaped groove teeth 10 in the fixed clamp body 1 are single-sided teeth, and the structure is changed from an overall double-sided straight tooth groove to an overall single-sided arc-shaped tooth groove, making opening and closing smoother and more convenient, thereby achieving rapid size adjustment and applicable scope. Widely applicable to water and electricity installations, industrial and mining enterprises, this improved tool eliminates the need for frequent pressing of the pivot pin, allowing for quick movement to the desired size simply by pulling it open. It provides a better grip when clamping objects 13. Traditional straight-arc grooved quick-release pliers have a small opening and limited clamping range. This device redesigns the grooves of the clamping body 1 into arc-shaped grooves 10, increasing the clamping range and making it more widely applicable. It allows for more convenient and faster clamping of objects. The improved arc-shaped grooves 10 have a larger opening and less impact during meshing.

[0023] Example 2, as Figure 1-5As shown, a groove 9 is provided on one side of the arc-shaped groove tooth 10 inside the fixed clamp body 1. One end of the ratchet tooth 11 abuts against the arc-shaped groove tooth 10. The angle of the groove 9 is parallel to the angle of the arc-shaped groove tooth 10. A plate opening 3 is provided on the outer side of the fixed clamp body 1. Both ends of the inner wall of the plate opening 3 are fixed with bosses 8. The bosses 8 slide in the groove 9. One end of the ratchet pin 5 is fixed to the plate opening 3. An object 13 is clamped between the fixed clamp body 1 and the plate opening 3.

[0024] The effect achieved by the entire embodiment 2 is as follows: when holding the fixed handle on the fixed clamp body 1, pulling the movable handle 2 upward, the ratchet body 6 rotates around the ratchet pin 5 as the center through the unlocking pin 4, which in turn rotates the ratchet body 6 and applies force to the compression spring 7, so that the ratchet teeth 11 separate from the arc-shaped groove teeth 10 of the fixed clamp body 1, and the plate opening 3 protrusion 8 moves quickly along the grooves 9 on both sides of the fixed clamp body 1. When clamping, when holding the fixed clamp body 1, pulling the movable handle 2 upward, the ratchet teeth 11 disengage from the arc-shaped groove teeth 10 of the fixed clamp body 1. Then, when the movable handle 2 is moved backward, the plate opening 3 protrusion 8 will move backward along the double grooves 9 on the fixed clamp body 1. The object 13 is placed between the fixed clamp body 1 and the plate opening 3. Pushing the movable handle 2 forward moves the plate opening 3 upward until the object 13 engages with the fixed clamp body 1, and the object 13 is quickly clamped.

[0025] Working principle: When using this device, hold the fixed handle on the fixed clamp body 1 and pull the movable handle 2 upwards. The unlocking pin 4 rotates around the ratchet pin 5, causing the ratchet body 6 to rotate and apply force to the compression spring 7. This causes the ratchet teeth 11 to separate from the arc-shaped grooves 10 of the fixed clamp body 1, allowing the protrusion 8 of the plate opening 3 to move quickly along the grooves 9 on both sides of the fixed clamp body 1. When clamping, hold the fixed clamp body 1 and pull the movable handle 2 upwards, causing the ratchet teeth 11 to disengage from the arc-shaped grooves 10 of the fixed clamp body 1. Then, move the movable handle 2 backwards, and the protrusion 8 of the plate opening 3 will move backwards along the double grooves 9 on the fixed clamp body 1. Place the object 13 between the fixed clamp body 1 and the plate opening 3. Push the movable handle 2 forward, causing the plate opening 3 to move upwards until the object 13 engages with the fixed clamp body 1, quickly clamping the object 13. This device features a single-sided arc-shaped tooth 10 within the fixed clamp body 1. The structure has been changed from a single-sided arc-shaped tooth groove to a double-sided straight tooth groove, resulting in smoother and more convenient opening and closing. This allows for rapid size adjustment and a wider range of applications, suitable for water and electricity installations, and industrial and mining enterprises. Compared to similar tools, the improved design eliminates the need for frequent pressing of the pivot pin, allowing for quick movement to the desired size simply by pulling it open. It also provides a better grip when clamping objects 13. Traditional straight arc-shaped tooth quick-release clamp wrenches have a small opening and limited clamping range. This device, by designing the tooth groove of the fixed clamp body 1 as an arc-shaped tooth groove 10, increases the clamping range, making it more widely applicable and enabling faster and more convenient object clamping. The improved arc-shaped tooth 10 has a larger opening and less impact noise during meshing.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
