Problems solved by technology

However, there are few dedicated pre-tightening tools at present, and users often pre-tighten with the help of ordinary tools such as needle-nose pliers, which makes the installation of the D ring time-consuming and laborious, and cannot achieve the ideal pre-tightening force.

Abstract

The invention relates to a D-ring bowstring pre-tightening tool. The D-ring bowstring pre-tightening tool comprises a first tong arm and a second tong arm rotationally connected through a pin shaft. Working sections are arranged at the portions, at one side of the pin shaft, of the first tong arm and the second tong arm respectively, and holding sections are arranged at the portions, at the other side of the pin shaft, of the first tong arm and the second tong arm. The D-ring bowstring pre-tightening tool is characterized in that the working section of the first tong arm comprises a first supporting arm stretching forwards and a second supporting arm located below the first supporting arm, two positioning grooves are formed in one side of the first supporting arm, and a first fixing pin stretching laterally is fixed to the other side of the first supporting arm; the working section of the second tong arm is located above the first supporting arm, a second fixing pin located above the portion between the two positioning grooves is laterally fixed to the working section of the second tong arm, and the end of the working section of the second tong arm is provided with a first groove allowing a D-ring bowstring to be inserted therein; the end of the second supporting arm is also provided with a second groove allowing the D-ring bowstring to the inserted therein. A D ring can be pre-tightened in a time-laboring and labor-saving mode, operation is convenient, and a user can smoothly and easily install the D ring.

Description

technical field [0001] The invention relates to a pretensioning tool, in particular to a D-ring bowstring pretensioning tool. Background technique [0002] Most of the traditional bows use fingers to pull the bowstring, and applying force to the same part of the bowstring for a long time will accelerate the wear and tear of the bowstring. In order to improve the service life of the bowstring and to cooperate with the application of the mechanical arrow release device (releasing device), a D-shaped rope ring (that is, the D ring) is currently set on the bowstring, and the shooter only needs to apply force to the D ring , you can pull the bowstring, and once the D ring wears out, you don't need to replace the whole bowstring, just replace the D ring and you're done. Therefore, the existence of the D ring not only facilitates the use of the release device, but also reduces the damage to the bowstring. And such a D ring also helps to improve the accuracy of archery. [0003] ...
