When the angle is adjusted to a proper angle, another athlete stops rotating the second cylindrical barrel 14.
The other player holds the grip 19 and rotates clockwise to rotate the push block 218 and the squeeze block 219 clockwise. When the pushing block 218 rotates clockwise to contact with the two left stoppers 213, the two left stoppers 213 move outwards, the compression spring 215 on the left side is compressed, when the pushing block 218 rotates clockwise to pass the two left stoppers 213, under the action of the compression spring 215 on the left side, the two left stoppers 213 reset inwards, another player continues to rotate the holding rod 19 clockwise, when the squeezing block 219 rotates clockwise to contact with the two left stoppers 213, the two left stoppers 213 move outwards, when the squeezing block 219 rotates clockwise to pass the two left stoppers 213, the left stopper 216 is clamped into the left catching groove 217 to fix the left stopper 213, at this time, the table tennis ball has rolled into the second cylindrical barrel 14, if the force for launching the table tennis ball needs to be increased, the other player continues to rotate the holding rod 19 clockwise to enable the squeezing block 219 to rotate clockwise to pass the right stopper 213, the clamping block 216 on the right side is clamped into the clamping groove 217 on the right side, the clamping block 213 on the right side is fixed, the holding rod 19 can be released by the other player, the striking plate 17 rotates anticlockwise to launch the table tennis ball, the connecting rod 214 can be pressed by the other player, the clamping block 216 moves out of the clamping groove 217, and the clamping block 213 moves to the initial position under the action of the compression spring 215. Thus, the force for serving the table tennis can be adjusted, and the table tennis can be prevented from not being launched because another player looses the grip 19 without rolling the table tennis into the second cylinder 14.
Another sportsman rotates rocker 9180 degree clockwise, drive the 6 clockwise rotations 180 degrees of bull stick, drive first sprocket 22 clockwise rotation 180 degrees, drive second sprocket 23 clockwise rotation 180 degrees through chain 24, thereby drive 16 clockwise rotations 180 degrees of pivot, and then drive and hit board 17 clockwise rotation 180 degrees, at this moment, the table tennis in the recess 8 falls in the slide 13, volute spiral spring 161 is turned round the book, another sportsman loosens rocker 9 again, under volute spiral spring 161's effect, hit board 17 anticlockwise rotation 180 degrees and launch the table tennis, and rocker 9 anticlockwise rotation to initial position, so on, convenient and fast.
Another sportsman can stir rocking rod 26 to the right, and little spring 27 is stretched, and rocking rod 26 swings right and drives and strikes pole 28 and swing left, makes and strikes pole 28 and strike box 11 to can make box 11 produce vibrations, make the table tennis in the box 11 can be better fall to the connecting pipe 10 in, then loosen rocking rod 26, under little spring 27's effect, rocking rod 26 swings left and resets.
