[0030] Refer to Figures 1-6 :

[0031] A ball collector of a tennis ball serving machine according to the present utility model is equipped with a rebound device, including a first mounting frame 1. Four corners of the top of the first mounting frame 1 are fixedly provided with first supports 2. The tops of the four first supports 2 are jointly fixedly provided with a second mounting frame 3. Four corners of the top of the second mounting frame 3 are fixedly provided with second supports 4. The tops of the four second supports 4 are jointly fixedly provided with a third mounting frame 5. A rebound net 7 is jointly fixed between the second mounting frame 3, the third mounting frame 5 and the two second supports 4. A recovery cloth 6 is arranged between the second mounting frame 3, the third mounting frame 5 and the other two second supports 4, and the recovery cloth 6 is parallel to the rebound net 7, and the recovery cloth 6 is located in front of the rebound net 7. A hollow support plate 10 is fixedly arranged in the first mounting frame 1. A ball serving machine main body 23 is arranged on the hollow support plate 10. A ball storage bin 24 is installed on the top of the ball serving machine main body 23. A positioning member for positioning the ball serving machine main body 23 is arranged on the hollow support plate 10. A conical ball guiding cloth 11 is fixedly arranged in the second mounting frame 3, and the conical ball guiding cloth 11 is located above the ball storage bin 24. The length of the vertical cross-section of the second mounting frame 3 gradually decreases from top to bottom.

[0032] Specifically, a protection net 9 is jointly fixed between the first mounting frame 1, the second mounting frame 3 and the two first supports 2. A shading cloth 8 is arranged between the first mounting frame 1, the second mounting frame 3 and the other two first supports 2, and the shading cloth 8 is parallel to the protection net 9, and the shading cloth 8 is located in front of the protection net 9. The shading cloth 8 is located directly below the recovery cloth 6, and the protection net 9 is located directly below the rebound net 7.

[0033] During use, pull the recovery cloth 6 to completely cover the elastic net 7. When the tennis ball machine main body 23 emits a tennis ball, the exerciser hits the tennis ball, causing the tennis ball to impact the recovery cloth 6. After the impact, the recovery cloth 6 will dent towards the direction close to the elastic net 7, and the tennis ball will move in the direction where the recovery cloth 6 dents. When the tennis ball stops moving, it will move downward under the action of gravity, that is, the tennis ball will fall into the conical ball guiding cloth 11 and then roll into the ball storage bin 24 from the conical ball guiding cloth 11, enabling the tennis ball to be directly recycled into the tennis ball machine main body 23 for continuous exercise.

[0034] Furthermore, the positioning member includes two rectangular slots 15 opened on the hollow support plate 10. A rectangular plate 14 is slidably connected in the rectangular slot 15. Both sides of the rectangular plate 14 are in contact with the inner walls on both sides of the rectangular slot 15. A clamping plate 12 is fixed to the top of the rectangular plate 14. Rubber pads 13 are fixed to one side of the two clamping plates 12 that are close to each other. A bidirectional screw 16 is rotatably connected in the hollow support plate 10, and the bidirectional screw 16 passes through the rectangular plate 14 and is threadedly connected to the rectangular plate 14. The thread directions of the two sections of the bidirectional screw 16 are opposite, and the two rectangular plates 14 are respectively located on different threaded sections of the bidirectional screw 16.

[0035] In addition, a slot hole 17 is opened in the shielding cloth 8, and the slot hole 17 is disposed opposite to the ball outlet of the tennis ball machine main body 23. Pulley 18 is installed at each of the four corners of the bottom of the mounting frame 1. A plurality of cloth strips 19 are fixed to the shielding cloth 8. A plush surface 20 and a hook surface 21 are provided on one side of the cloth strip 19.

A plurality of round holes 22 are opened at the top of the recovery cloth 6, and a hanging ring 25 passes through the round hole 22, and the hanging ring 25 is slidably fitted on the mounting frame 3 5.

[0036] During use, pull the recovery cloth 6 to make the hanging rings 25 approach each other, that is, pull the recovery cloth 6 to one side of the support frame 2 4 so that the recovery cloth 6 no longer covers the elastic net 7. At this time, when the tennis ball machine main body 23 emits a tennis ball and the exerciser hits the tennis ball onto the elastic net 7, the tennis ball will rebound, and rebound training can be carried out. Moreover, it can be switched between the tennis ball machine training and the rebound training, increasing the variety of exercises.

[0037] It should be noted that through the setting of the cloth strip 19, after the cloth strip 19 is wrapped around the mounting frame 2 3 and the support frame 1 2 and the plush surface 20 and the hook surface 21 are adhered to each other, the shielding cloth 8 is fixed in front of the tennis ball machine main body 23. When the tennis ball machine main body 23 serves, the tennis ball passes through the slot hole 17, and the shielding cloth 8 protects the tennis ball machine main body 23 to prevent the hit-back tennis ball from impacting the tennis ball machine main body 23 and causing damage to the tennis ball machine main body 23. The setting of the plush surface 20 and the hook surface 21 on the cloth strip 19 facilitates the installation and disassembly of the shielding cloth 8.
