Problems solved by technology
[0002] When the current hollow wrench is in use, it generates a lot of heat, and the heat dissipation basically depends on the body of the wrench to dissipate it. Because the heat is not dissipated in time, it is easy to cause damage to the blade on the wrench body. Over time, the wrench is scrapped, and sometimes In the case of damaged blades, it is easy to produce unqualified threads, resulting in unqualified products. Moreover, the current hollow wrench teeth are fixed and cannot be fine-tuned, because any object has an expansion coefficient. At a specific temperature For a moment, the threads made with fixed hollow wrench teeth are often unqualified, resulting in scrapped products

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] A single-side adjustable hollow wrench with cooling holes, such as figure 1 , figure 2 As shown, it includes a wrench body 1, a blade portion 2, a bayonet 3, a cooling hole 4, and an adjustable device 5; On both sides, the heat dissipation holes 4 are between the blades 2, and the adjustable device 5 is installed on one side of the wrench body 1, that is, a single-side adjustable hollow wrench with heat dissipation holes is formed.
[0017] The specific operation is as follows: first, insert the rotating tool into the bayonet 3 on the top of the puller body 1, adjust the adjustable device 5 to a suitable position according to the expansion system of the material, rotate the rotating tool, and press the handle at one end of the puller body 1. The blade part 2 will make qualified threads on the inner wall of the processed part. Since there are cooling holes 4 b...

The invention relates to a unilaterally adjustable hollow screw die with heat emission holes. The unilaterally adjustable hollow screw die comprises a screw die body, blades, bayonets, the heat emission holes and an adjustable device. The blades are arranged at the inner side of one end of the screw die body; the bayonets are respectively located at both sides of the screw die body; the heat emission holes are formed between the blades; the adjustable device is arranged at one side of the screw die body. The unilaterally adjustable hollow screw die provided by the invention has the advantages that heat emission is fast; the service life of the screw die is long; the product scrap rate is reduced greatly; more accurate threads can be manufactured according to different expansion factor.
Description
technical field [0001] The invention relates to a wrench, in particular to a single-side adjustable hollow wrench with cooling holes. Background technique [0002] When the current hollow wrench is in use, it generates a lot of heat, and the heat dissipation basically depends on the body of the wrench to dissipate it. Because the heat is not dissipated in time, it is easy to cause damage to the blade on the wrench body. Over time, the wrench is scrapped, and sometimes In the case of damaged blades, it is easy to produce unqualified threads, resulting in unqualified products. Moreover, the current hollow wrench teeth are fixed and cannot be fine-tuned, because any object has an expansion coefficient. For a moment, the threads made with fixed hollow wrench teeth are often unqualified, resulting in scrapped products. Contents of the invention [0003] The object of the present invention is to provide a single-side adjustable hollow wrench with cooling holes, which overcomes ...
