Description

Technical Field

[0001] The utility model relates to the field of wrenches, in particular to a ratchet long-handled universal wrench. Background Art

[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fasteners with openings or holes. A wrench usually has an opening or hole for clamping the bolt or nut at one or both ends of the handle. When in use, external force is applied to the handle along the direction of thread rotation to turn the bolt or nut.

[0003] The universal wrenches currently on the market have the following problems when used:

[0004] 1. Commonly used ratchet long-handled wrenches, the wrenches with a cylindrical front end are of an integrated structure, and the wrench head at the front end is manufactured according to the specifications of the screws and nuts, so that the wrenches can only be used for screws and nuts of the same specifications and cannot be adjusted according to the model;

[0005] 2. When a ratchet long-handled wrench with cylinders at both ends is used, once a component is damaged, other intact components will also become unusable and cannot be disassembled for recycling. The design of this structure increases the loss of the ratchet long-handled wrench. Therefore, a ratchet long-handled universal wrench is proposed to address the above problem. Utility Model Content

[0006] In order to make up for the shortcomings of the prior art, the wrench can only be used for screws and nuts of the same specification and cannot be adjusted according to the model.

[0028] Further, the main body mechanism 1 includes a handle 101, a wrench head 102, a built-in groove 103, a positioning rod 104, a groove 105 and a stop block 106. The wrench head 102 is fixedly assembled at the left and right ends of the handle 101, the built-in groove 103 is fixedly arranged inside the wrench head 102, the positioning rod 104 is fixedly arranged at the upper end of the wrench head 102 and located at the side of the built-in groove 103, the groove 105 is fixedly arranged in the middle of the inner end of the built-in groove 103, and the stop block 106 is fixedly assembled in the middle of the inner end of the built-in groove 103 and extends to the upper and lower ends of the groove 105;

[0029] During operation, by setting the groove 105, the thickness of the groove 105 is smaller than the thickness of the gasket 207, so that the gasket 207 can be inserted into the corresponding groove 105 during installation, thereby increasing the convenience of using the gasket 207. At the same time, the gasket 207 with a soft structure is not limited by the groove 105 and can be freely assembled.

[0030] Furthermore, the auxiliary mechanism 3 includes a movable block 301 and a clamping spring 302, and the clamping spring 302 is fixedly connected to the inner end of the movable block 301;

[0031] During operation, the movable block 301 can be moved by providing the retaining spring 302 , thereby increasing the convenience of installing the sleeve 201 .

[0032] Furthermore, the sleeve 201 is movably mounted inside the built-in groove 103, and the number of the assembly grooves 202 is four;

[0033] During operation, by movably installing the sleeve 201 inside the built-in groove 103, when the main mechanism 1 at the outer end of the device is damaged or parts of the movable mechanism 2 are damaged, the sleeve 201 and the wrench 102 can be disassembled to facilitate the continued use of other parts, thereby saving the cost of the device. At the same time, the number of assembly grooves 202 is four, so that the sleeve 201 can be installed with the movable block 301 in four directions.

[0034] Furthermore, the diameter of the snap ring 203 is larger than the diameter of the built-in groove 103, the positioning holes 204 are distributed in an annular shape inside the snap ring 203, and the limiting grooves 206 are symmetrically distributed at the outer end of the sleeve 201. When the sleeve 201 is installed;

[0035] During operation, the upper end of the sleeve 201 is provided with a limiting structure by setting the clamping ring 203, and then the positioning hole 204 is aligned with the positioning rod 104, so that the sleeve 201 can maintain a fixed position after installation to avoid sliding during use.

[0036] Furthermore, the wrench heads 102 are symmetrically distributed at the left and right ends of the handle 101, the outer end of the handle 101 is an arc-shaped structure, the number of the positioning rods 104 is the same as the number of the positioning holes 204, the grooves 105 and the washers 207 correspond to each other, and the limit blocks 106 and the limit grooves 206 are adapted;

[0037] When working, the outer end of the handle 101 is an arc-shaped structure, which increases the convenience of holding the device when operating. The symmetrically arranged wrenches 102 allow the device to simultaneously install sleeves 201 with ratchet bodies 205 of different structures, making the device more applicable when used.

[0038] Further, the movable block 301 is movably installed inside the assembly groove 202, the movable block 301 is a T-shaped structure, the inner end of the movable block 301 is an arc structure, the inner end of the clamping spring 302 is adapted to the inner end of the assembly groove 202, and the number of the clamping spring 302 is several;

When the lower end of the sleeve 201 is exposed from the lower end of the wrench head 102, the movable block 301 is quickly rebounded by the retaining spring 302 to clamp the bottom of the sleeve 201, thereby preventing the sleeve 201 from falling off from the wrench head 102 during use. In this structure, the movable block 301 is also set as a T-shaped structure, so that it will not fall off from the sleeve 201 under repeated force, thereby increasing the stability of the connection between the components of the device.

[0040] Working principle: The technical solution of the utility model is a ratchet long-handled universal wrench. By setting a spanner head 102 and a sleeve 201, the device is a split structure. During assembly, the sleeve 201 is movably installed inside the built-in groove 103. When the main body mechanism 1 at the outer end of the device is damaged or a part of the movable mechanism 2 is damaged, the sleeve 201 and the spanner head 102 can be disassembled to facilitate the continued use of other parts, thereby saving the cost of the device. At the same time, the number of assembly grooves 202 is four, so that the sleeve 201 can be installed with the movable block 301 in four directions, and the setting of the outer retaining ring 203 at the upper end of the sleeve 201 makes the upper end of the sleeve 201 have a limited position structure, and then the positioning hole 204 corresponds to the positioning rod 104, so that the sleeve 201 is secured after installation. The movable block 301 is held in a fixed position to avoid sliding during use. The various components of the device complement each other. When the wrench head 102 and the sleeve 201 are connected, the movable block 301 is pressed by hand so that the outer end of the movable block 301 is compressed and deformed by the retaining spring 302 and retracted into the interior of the assembly groove 202, thereby completing the installation of the sleeve 201. When the lower end of the sleeve 201 is exposed from the lower end of the wrench head 102, the movable block 301 is quickly rebounded by the retaining spring 302 to clamp the bottom of the sleeve 201, thereby preventing the sleeve 201 from falling off from the wrench head 102 during use. In this structure, the movable block 301 is also set as a T-shaped structure so that it will not fall off from the sleeve 201 under repeated force, thereby increasing the stability of the connection between the components of the device.
