Description

Technical Field

[0001] The utility model belongs to the technical field of ratchet wrenches, in particular to an extended ratchet wrench. Background Art

[0002] A ratchet wrench is a screw tightening tool that can conveniently adjust the use angle of the wrench. It has the characteristics of strong applicability, easy use and low cost.

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

[0004] 1. The overall length of the traditional ratchet wrench is relatively short, which results in the operator being limited by the length of the wrench when facing some tight bolts, and being unable to effectively tighten the bolts. It requires more force to tighten the bolts, which is not so convenient to use and the functionality needs to be improved;

[0005] 2. Generally, ratchet wrenches are not equipped with anti-slip devices during use. Operators may sometimes be injured or have accidents due to hand slip or improper operation. In addition, long-term use of ratchet wrenches without anti-slip devices may also cause hand fatigue, wear and discomfort. Utility Model Content

[0026] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0027] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an extended ratchet wrench of the utility model in conjunction with the accompanying drawings.

[0028] like Figure 1-4As shown, an extended ratchet wrench of the utility model comprises a sliding handle 1, the interior of the sliding handle 1 is slidably connected to a spring buckle 2, and the bottom of the spring buckle 2 is provided with a spring, so that the operator only needs to press the spring buckle 2 downward to achieve the effect of extending and adjusting the ratchet wrench, which is more convenient to use. The outside of the sliding handle 1 is sleeved with a sliding sleeve 3, and a spring hole 4 is provided inside the sliding sleeve 3. The spring buckle 2 is clamped in the spring hole 4. Through the combination of the sliding handle 1 and the sliding sleeve 3, the ratchet wrench can be lengthened in this way, which can not only effectively increase the torque and tighten the bolts, but also adapt to the tightening operations of screws at different angles, which is more convenient.

[0029] The surface of the sliding sleeve 3 is fixedly connected to the anti-skid pad 5, and a spring buckle 2 is provided inside the anti-skid pad 5. The anti-skid pad 5 is equidistantly distributed. By installing the anti-skid pad 5 on the surface of the sliding sleeve 3, the friction between the ratchet wrench and the hand can be increased, making the operation more stable and accurate, avoiding accidents or injuries caused by hand slippage or improper operation, and improving work efficiency. In addition, the installation of the anti-skid pad 5 can also effectively extend the service life of the ratchet wrench, making it more durable.

[0030] A bracket 6 is provided on the side of the sliding handle 1, and the side of the bracket 6 is fitted on the side of the ratchet head 7. The bracket 6 can fit the ratchet head 7 when the ratchet wrench is retracted, so that the overall structure is more stable.

[0031] The side of the sliding sleeve 3 is fixedly connected to the ratchet head 7, and the inside of the ratchet head 7 is slidably connected to the rim 8. The rim 8 can rotate along the ratchet head 7 in a directional manner, which can effectively simplify the steps for the operator to tighten the screws, making it more convenient to tighten or loosen the screws.

[0032] The inside of the wheel rim 8 is fixedly connected with the folding blocks 9, which are symmetrically distributed. The folding blocks 9 are used to clamp the heads of the bolts to prevent them from sliding and deviating during the tightening process.

[0033] The side of the sliding handle 1 is fixedly connected to the wrench head 10, and a jaw 11 is provided inside the wrench head 10. The jaw 11 can clamp the bolt, and then the bolt can be unscrewed by rotating the wrench, which is relatively convenient to operate.

[0034] The working principle of the extended ratchet wrench: when using the extended ratchet wrench, you only need to press the spring buckle 2 on the ratchet wrench and drag the sliding handle 1 to adjust it to a suitable position, then the spring buckle 2 will pop out by itself and jam the spring hole 4. The combination of the sliding handle 1 and the sliding sleeve 3 can effectively increase the length of the ratchet wrench, which can not only effectively increase the torque and tighten the bolt, but also adapt to the tightening operation of screws at different angles, which is more convenient. An anti-skid pad 5 is installed on the surface of the sliding sleeve 3, which can increase the friction between the ratchet wrench and the hand, making the operation more stable and accurate, avoiding accidents or injuries caused by hand slip or improper operation, and improving work efficiency. In addition, the installation of the anti-skid pad 5 can also effectively extend the service life of the ratchet wrench and make it more durable. After adjusting to a suitable length, you only need to connect the ratchet wrench to the screw to be tightened, and then drive the sleeve fixed on the wrench to achieve the disassembly and installation of the bolt or nut by reciprocating the wrench, especially in a narrow or difficult to access place. The invention relates to a method for removing a bolt or nut at a certain position, and a method for removing a bolt or nut at a certain position to improve the working efficiency of the tool.
