In the process of training the hitting of the ping-pong, when people need to serve, firstly, people move the equipment to a training site of the ping-pong, then the fixing mechanism 2 is operated, then the edge of the table is positioned between the support frame 1 and part of the fixing mechanism 2, then the fixing mechanism 2 fixes the equipment on the table, then people operate the serving mechanism 3, and place the ping-pong one by one in the serving mechanism 3, so that the ping-pong is continuously sent out in different directions, thus achieving the effect of automatic serving, after the training of hitting of the ping-pong is finished, people stop the serving mechanism 3, then leave the equipment from the table, so that the fixing mechanism 2 stops operating and returns to the original position, then people move the equipment back to the original position, and if the equipment is used again, the steps are repeated.

The table tennis table is characterized in that a user manually moves the clamping plate 24 upwards, the first telescopic rod 22 is shortened, the first spring 23 is changed into a compressed state from an initial state, the user positions the edge of the table between the clamping plate 24 and the supporting frame 1, then the clamping plate 24 is loosened, the first spring 23 is still in the compressed state, the clamping plate 24 and the supporting frame 1 clamp the edge of the table through elastic force, the supporting frame 1 is fixed, the equipment is further fixed, the ball serving mechanism 3 can serve balls stably, after the hitting training of a table tennis ball by a soldier is completed, the user moves the supporting frame 1, the edge of the table is pulled out from between the clamping plate 24 and the supporting frame 1, at the moment, the first spring 23 is reset from the compressed state, and the clamping plate 24 is moved back to the original position through the elastic force.

After one holds the device, one puts one soldier ping ball in the ball serving pipe 38, and opens the air cylinder 33, the air cylinder 33 operates to move the push plate 34 to the left, and simultaneously one manually prevents the push block 36 from moving, so that the push plate 34 slides to the left on the first slide bar 35, the second spring 37 is changed from the initial state to the compressed state, then one releases the push block 36, the second spring 37 is still in the compressed state, the elasticity enables the push block 36 to rapidly slide to the left in the mounting frame 32, and further the soldier ping ball is pushed out, thereby achieving the automatic ball serving effect, simultaneously the push block 36 enables the first slide bar 35 to slide to the left in the push plate 34, then the air cylinder 33 continues to operate, so that the push plate 34 moves back to the right and the original position, simultaneously the second spring 37 is reset from the compressed state, so that the first slide bar 35 and the push block 36 move back to the soldier ping ball, and simultaneously, the ball serving pipe 38 is manually moved forward or backward, thereby serving balls in different directions, the ball serving pipe 38 moves to rotate the mounting frame 32, so that the first rotating shaft 31 rotates, and the air cylinder 33 and the push block 36 move, the air cylinder 33 moves to move the push plate 34, and the first slide bar 35 moves, after the training of hitting the table tennis by a soldier is completed, a person closes the air cylinder 33, so that the push plate 34 and the push block 36 stop moving, and meanwhile, the person does not rotate the ball serving pipe 38 any more.

When the push plate 34 moves leftwards, the push plate 34 drives the first wedge-shaped block 41 to move leftwards, at the moment, the second spring 37 changes from the initial state to the compressed state due to the fact that the second wedge-shaped block 47 is matched with the push block 36, the purpose of energy storage is achieved, when the first wedge-shaped block 41 is moved to be in contact with the connecting plate 44, the first wedge-shaped block 41 enables the connecting plate 44 to move downwards, the second telescopic rod 42 is shortened, the third spring 43 changes from the initial state to the compressed state, in addition, the connecting plate 44 moves downwards to drive the third telescopic rod 45 to move downwards, the second wedge-shaped block 47 further moves downwards, when the second wedge-shaped block 47 is separated from the push block 36, the second spring 37 is still in the compressed state, the push block 36 moves leftwards rapidly due to the elastic force, the billiards are pushed out, then the push plate 34 moves rightwards to the original position, the third spring 43 returns from the compressed state, and the connecting plate 44 and the second wedge-shaped block 47 moves back, then the pushing block 36 moves back to the right to the original position, when the pushing block 36 moves to contact with the second wedge-shaped block 47, the pushing block 36 enables the second wedge-shaped block 47 to move downwards, the third telescopic rod 45 shortens, the fourth spring 46 changes from the initial state to the compressed state, the pushing block 36 is separated from the second wedge-shaped block 47, and the fourth spring 46 is reset from the compressed state, so that the second wedge-shaped block 47 moves back to the original position upwards.

After the training of hitting the table tennis is completed, the person turns off the first servo motor 52, so that the second slide bar 56 stops moving, and the ball serving pipe 38 stops moving.

People pour a proper amount of the soldier's ping-pong balls into the storage basket 62, when the push plate 34 moves rightwards, the push plate 34 enables the push rod 65 to slide rightwards in the blanking channel 64, at the moment, one soldier's ping-pong ball in the storage basket 62 falls into the blanking channel 64 due to gravity, when the push plate 34 moves leftwards, the push plate 34 moves to enable the push rod 65 to move leftwards and return to the original position, further the soldier's ping-pong ball in the blanking channel 64 is pushed to move leftwards, meanwhile, the rest of the soldier's ping-pong balls in the storage basket 62 are prevented from moving downwards, and then the soldier's ping-pong ball falls into the ball serving pipeline 38 due to gravity, so that the purpose of automatic blanking is achieved.

After people pour the soldier's ping-pong into the storage basket 62, the second servo motor 71 is started, the output shaft of the second servo motor 71 rotates to drive the transmission assembly 72 to rotate, and further the third rotating shaft 73 rotates, so that the stirring stick 74 rotates, and then the soldier's ping-pong in the storage basket 62 is pushed, the purpose of automatically stirring materials is achieved, more soldier's ping-pong can be poured into the blanking channel 64, and after the soldier's ping-pong striking training is completed, people close the second servo motor 71, so that the stirring stick 74 stops rotating.
