Description

A fast clamping and pulling head

technical field

The utility model relates to a racket threading machine, in particular to a puller head installed on a slide rail type puller device for clamping the racket string. When the puller device is started to move, a pair of clamping blocks clamp the racket string synchronously. , easy to operate.

Background technique

Tennis rackets, badminton rackets and other equipment use the racket string to weave to form a net-like hitting surface. The tension of the hitting surface depends on the tensile stress value generated by stretching the racket string when the racket string is weaving. The threading of the racket string is easy and the tensile stress value can be accurately controlled. Generally, the racket stringing machine is used for the stringing operation; The action of the device promotes the displacement of the cable head, and the racket string tends to be in a tensioned state.

A wire-drawing head of a racket stringing machine in the prior art can activate the wire-drawing device synchronously when clamping the racket string, so as to improve the convenience of operation; the above-mentioned wire-drawing head mainly includes a base, a For the clamping block and an operating piece, wherein the base has two vertical walls facing each other, the clamping block is arranged between the vertical walls, and a narrow and long gap is formed between the clamping blocks, so that the racket string can be inserted Between the clamping blocks, the racket strings are relatively clamped by the clamping blocks, and the wire pulling operation is carried out. The operating piece is pivotally arranged at one end of the base, and a first switch is arranged between each vertical wall of the base body, and the first switch has a spring piece, and the operating piece is adjacent to the first switch, so as to touch the elastic piece For deflection, and for controlling the pull wire device; a second switch is set between each vertical wall adjacent to a clamp block, and the second switch has a shrapnel that is pressed by the clamp block, and is released when the clamp block slides. The suppressing effect of the shrapnel can synchronously start the operation of the pulling device, so as to pull the racket string to make it stretch, and improve the convenience of use.

When the racket string is clamped by the above-mentioned pull head, the racket string enters the narrow and long gap between the clamping blocks, and extends to the rear end of the clamping block through the gap, and then pulls the racket sideways when the racket string is in a stretched state Then the racket string forms a pushing effect on the rear end of a clamping block, so that each clamping block slides axially, and each clamping block slides in the axial direction, and also relatively moves and clamps the racket string. At this time, due to The relative friction between the racket string and the clamping blocks makes the clamping blocks unable to reset themselves, so as to maintain the clamping state of the racket strings by the clamping blocks, and when the racket string is pulled to promote the sliding of the clamping blocks, Simultaneously release the pressing effect of the clip block on the shrapnel of the second switch, then the shrapnel will act to make the second switch send a signal, start the operation of the backguy device, and pull the racket string to make it stretch.

In the prior art, when the wire pulling head clamps the racket string to carry out wire pulling operations, the operator pulls the racket string through the gaps between the clamps, and pulls the racket string sideways to make it stop the clamps to slide, and simultaneously starts the pull wire The device works, however, the user pulls the racket string sideways, so that the racket string pulls the clamp block during the sliding process. Since the racket string has a small diameter, the user clamps the tiny racket string with his fingers and applies it. In the process of pulling the clip to slide, the fingers are not easy to effectively control the racket string, and the racket string tends to slide relative to the fingers. The reliability of the racket string to pull the clip to slide is not enough, and the convenience of use needs to be improved. .

Utility model content

Aiming at the deficiencies in the prior art, the utility model provides a fast clamping and pulling head, which synchronously activates the pulling device when clamping the racket string, thereby improving the convenience of operation.

In order to achieve the above object, the technical solution of the utility model is:
