Wire-drawing device height adjustment device of wire-drawing device head of racket wiring device

Abstract

The invention provides a device for adjusting the height of the string grip of the string drawing machine head of a racket stringing machine. The base body of string drawing machine head is divided into an upper base and a lower base, the string grip is connected on the upper base, and the a connection base is obliquely fixed on the base of the lower base; a slide rail is disposed on the connected base; and the upper base is pivotally connected with the slide rail via a sliding base, so that the height of the string grip can be adjusted when the string grip moves on the sliding base. Therefore, according to the stringing operations of racket frames with different thicknesses, the racket frame and the string of the string grip of the string drawing machine head can be adjusted at the same level, thereby preventing the racket string from being worn and the racket frame from being damaged, the stringing poundage is accurate; and the racket can not collide against the string grip when turning.

Description

technical field [0001] The invention relates to a wire puller height adjustment device of a wire puller head of a racket threading machine, in particular to a wire puller height adjustment device structure which can improve threading quality and is easy to operate. Background technique [0002] By the way, netting and badminton are sports that combine strength, delicacy, and wits. The strength of swinging the racket can be large or small. main factor. And whether the threading method of the racket string is appropriate or not is one of the factors that affect the service life of the racket and the racket string. [0003] Secondly, the racket threading machine mainly has a base a, a holding frame b and a wire drawing head c (such as figure 1 ), the holding frame b is pivotally connected to the top of the base a, and can be rotated 360 degrees and can be positioned, while the wire pulling head c has a wire puller c1 and a wire rod c2, and the wiring head c has a horizontal ...

AI Technical Summary

Problems solved by technology

[0006] 1. The racket frame d and the string e are damaged: because the thickness of the racket frame d of various brands may not be the same height, but the holding frame b and the cable head c are of a fixed height, so the racket string e is threaded on the cable After the wire puller c1 of the machine head c is between the racket frame d, an angle θ is generated between the racket frame d and the outer string e (as shown in Figure 2), and when the string e is under tension, the racket frame d due to friction And the force is uneven, resulting in inaccurate pounds; and there will be friction, damage, or even breakage between the perforation (thread eye grain) of the racket frame d and the racket string e. When hitting the ball, the structure of the racket frame d and the racket string e has been damaged, so when the racket is swung to hit the ball, the racket frame d or the racket string e are easy to break, which reduces the service life of the racket frame d and the racket string e. Inaccurate, which affects the performance of the game and reduces the interest in net and badminton

[0007] 2. When the racket frame d turns, it will touch the puller c1 of the pull head c: because the thickness of the racket frame d of various brands may not be the same height, but the holding frame b and the pull head c are fixed heights and cannot be adjusted. Therefore, when the racket frame d turns, the handle d1 of the racket frame d will touch the wire puller c1 of the puller head c (see also Figures 3 and 4), making it unable to rotate 360 ​​degrees, which is unfavorable for operation
