[0031] The utility model will be further described in connection with the drawings, and the protection scope of the utility model is not limited to the following:

[0032] As Figures 2-9 shown, a racket fixing device capable of quickly fixing a tennis racket comprises a base 3, left and right clamping assemblies 4 and 5 are arranged on the base 3 and located at the left and right sides thereof respectively, and the left clamping assembly 4 and the right clamping assembly 5 are arranged symmetrically left and right.

[0033] The left clamping assembly 4 includes a column 6 fixed to the top surface of the base 3 and a groove 7 formed on the top surface of the column 6. A lead screw 8 is rotatably installed between the left and right side walls of the groove 7. The left end of the lead screw 8 passes through the column 6 to the left, and a knob 19 is fixedly connected to the extended end. A threaded sleeve 9 that slides with the groove 7 is threaded onto the lead screw 8. Pins A10 are fixed on the top surface of the column 6 and on the front and rear sides of the groove 7. Bending parts 11 are hinged to both pins A10. The two bending parts 11 are arranged opposite each other and symmetrically arranged. The inner ends of the two bending parts 11 are... The pin shaft B12 is hinged to the top surface of the threaded sleeve 9. The outer ends of the two bent parts 11 extend directly above the base 3, and a U-shaped retainer 13 is fixed on the extended end. A U-shaped buffer pad is fixed inside the U-shaped retainer 13. The U-shaped retainers 13 on the two bent parts 11 are opposite to each other. The right end of the lead screw 8 passes through the column 6 to the right, and a movable seat 14 is threaded on the extended end. A guide rod 15 is fixed on the lower end of the movable seat 14. The guide rod 15 slides to the left through the column 6. A guide hole corresponding to the guide rod 15 is opened in the column 6. The guide rod 15 is slidably installed in the guide hole.

[0034] The upper end of the movable seat 14 of the left clamping assembly 4 is fitted with a high-pressure protector I16, and the high-pressure protector I16 has multiple wire holes 17. The upper end of the movable seat 14 of the right clamping assembly 5 is fitted with a high-pressure protector II18, and the outer end face of the high-pressure protector II18 is an arc-shaped surface.

[0035] The working process of this utility model is as follows:

[0036] S1, the worker is holding... Figure 1 The tennis racket handle 1 is shown, and the tennis racket frame 2 is fitted over the high tension protectors I16 and II18, as shown. Figure 10 As shown, and ensure that the tennis frame 2 is positioned between the two U-shaped brackets 13 of the left clamping component 4 and the two U-shaped brackets 13 of the right clamping component 5;

[0037] S2. The worker rotates the knob 19 of the left clamping assembly 4 with his left hand. The knob 19 drives the lead screw 8 to rotate. Under the threaded engagement of the lead screw 8 and the screw sleeve 9, the screw sleeve 9 moves to the left along the lead screw 8. The screw sleeve 9 drives the two pins B12 to move to the left synchronously. At this time, the bent part 11 rotates relative to the pin A10. The bent part 11 drives the U-shaped card seat 13 to rotate synchronously on the horizontal plane and move towards the outer edge of the tennis frame 2. At the same time, under the engagement of the lead screw 8 and the moving seat 14, the moving seat 14 moves to the left along the lead screw 8. The moving seat 14 drives the high-pressure protector I16 to move to the left and towards the left edge of the tennis frame 2.

[0038] When the knob 19 is rotated to a certain number of turns, the two U-shaped clamping seats 13 of the left clamping assembly 4 hold the left half of the tennis racket frame 2, and at the same time, the high-pound protector I 16 of the left clamping assembly 4 abuts against the left edge of the tennis racket frame 2;

[0039] S3, the worker rotates the knob 19 of the right clamping assembly 5 with the right hand, the knob 19 drives the screw rod 8 to rotate, under the cooperation of the screw rod 8 and the screw sleeve 9, the screw sleeve 9 moves along the screw rod 8 to the right, the screw sleeve 9 drives the two pin shafts B12 to move to the right, at this time, the bent piece 11 rotates relative to the pin shaft A10, the bent piece 11 drives the U-shaped clamping seat 13 to rotate synchronously in the horizontal plane and moves towards the outer edge of the tennis racket frame 2; at the same time, under the cooperation of the screw rod 8 and the moving seat 14, the moving seat 14 moves along the screw rod 8 to the right, the moving seat 14 drives the high-pound protector II 18 to move to the right and towards the right edge of the tennis racket frame 2;

[0040] When the knob 19 is rotated to a certain number of turns, the two U-shaped clamping seats 13 of the right clamping assembly 5 hold the right half of the tennis racket frame 2, and at the same time, the high-pound protector II 18 of the right clamping assembly 5 abuts against the right edge of the tennis racket frame 2, thereby finally fixing the tennis racket frame 2 and further fixing the tennis racket;

[0041] It can be known from steps S2-S3 that the worker only needs to rotate the knob 19 of the left clamping assembly 4 and the knob 19 of the right clamping assembly 5, so as to fix the tennis racket frame 2 through the U-shaped clamping seat 13 and further quickly fix the tennis racket. It can be known that, compared with the traditional racket fixing device, the racket fixing device does not need the worker to operate the wire clamp one by one to make the wire clamp hold the tennis racket frame 2, realizes the quick fixing of the tennis racket in a short time, greatly improves the fixing efficiency of the tennis racket, and further improves the subsequent threading efficiency.

[0042] S4, the worker can thread the tennis string in the tennis racket through the special string pulling tool, thereby realizing the threading of the string in the tennis racket frame 2 of one tennis racket;

[0043] S5, after the threading is completed, the worker reversely rotates the knob 19 of the left clamping assembly 4 and the knob 19 of the right clamping assembly 5 with the left and right hands respectively, at this time, the U-shaped clamping seat 13, the high-pound protector I 16 and the high-pound protector II 18 are separated from the tennis racket frame 2, and after the separation, the worker takes away the racket with the threaded tennis string;

[0044] S6, the worker repeats the operation of steps S1-S5, thereby continuously threading the string in the tennis racket frames 2 of multiple tennis rackets.

[0045] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments.
