[0002] The tennis racket threading machine is used for threading elastic line in the tennis racket, and when all the elastic lines are threaded in the tennis racket, the finished product tennis racket can be produced. The core component of the tennis racket threading machine is the seat clamp, which has the function of clamping and fixing one end of the elastic line and can also pull the clamped end of the elastic line to the specified position.

[0003] The structure of a seat clamp is shown in Figures 1-3 It comprises an arc-shaped guide rail 1 fixed on the main body of the tennis racket threading machine, a sliding mounting seat 2 supported on the top surface of the arc-shaped guide rail 1 and slidable along the length direction of the arc-shaped guide rail 1, an installation rod 3 fixed on the top surface of the sliding mounting seat 2, a line clamp connected to the installation rod 3 for clamping one end of the elastic line, a connecting block 6 fixed on the bottom surface of the sliding mounting seat 2 and penetrating the arc-shaped slot 5 of the arc-shaped guide rail 1, a limiting seat 8 fixed on the bottom surface of the extending end of the connecting block 6, two circular sliding blocks 14 fixed on the top surface of the limiting seat 8, the two circular sliding blocks 14 being respectively located on the left and right sides of the connecting block 6, and the two circular sliding blocks 14 being in sliding fit with the arc-shaped slot 5 of the arc-shaped guide rail 1; the top surface of the limiting seat 8 is in contact with the bottom surface of the arc-shaped guide rail 1.

[0004] The working method of the seat clamp is as follows: the worker first clamps and fixes one end of the elastic line by using the line clamp; then the worker pushes the sliding mounting seat 2 by hand, and the sliding mounting seat 2 moves along the length direction of the arc-shaped guide rail 1, at the same time, the sliding mounting seat 2 drives the line clamp, the connecting block 6, the limiting seat 8 and the two circular sliding blocks 14 to move synchronously, wherein the line clamp pulls the clamped elastic line towards the specified position, and the two circular sliding blocks 14 move along the length direction of the arc-shaped slot 5 of the arc-shaped guide rail 1; when the sliding mounting seat 2 moves to the set position, the clamped end of the elastic line can be pulled to the specified position.

[0005] However, although this seat clamp can pull the elastic line, it still has the following technical defects in technology:
