[0039] like Figure 1 and Fig.13 As shown, it also includes a rotating mechanism 14, which includes a worm 141, a handwheel 142 and a worm gear 143. The right part of the mounting seat 3 is rotatably connected to the worm 141, the rear end of the worm 141 is connected to the handwheel 142 through a key, and the bottom end of the screw 6 is connected to the worm gear 143 through a key, and the worm gear 143 is meshed with the worm 141.

[0040] like Figure 4As shown, a storage box 15 is also included. The two sides of the two boxes 111 that are close to each other are connected with the storage box 15 by bolts, and the binding belt 116 is placed in the storage box 15.

[0041] Initially, the fourth elastic member 127 is in a compressed state. The athlete can adjust the height of the touch rod 9 according to his or her own height. The hand wheel 142 is turned to drive the worm 141 to rotate, the worm 141 drives the worm wheel 143 to rotate, the worm wheel 143 drives the screw rod 6 to rotate, the screw rod 6 drives the sleeve rod 5 to move upward, thereby driving the touch rod 9 to move upward, and the hand wheel 142 is turned in the opposite direction to drive the worm 141 to rotate in the opposite direction, the worm 141 drives the worm wheel 143 to rotate in the opposite direction, the worm wheel 143 drives the screw rod 6 to rotate in the opposite direction, the screw rod 6 drives the sleeve rod 5 to move downward, thereby driving the touch rod 9 to move downward, and the height of the touch rod 9 is adjusted to adapt to athletes of different heights. The moving distance of the touch rod 9 can be known through the scale line, so that the touch rod 9 can be accurately adjusted to the appropriate height. After adjusting the height of the touch bar 9, the athlete opens the box cover 112, and then selects a suitable number of weight plates 113 according to his own conditions, adjusts the exercise intensity, rotates the screw 114 to move upward, and the weight plates 113 are separated from the screw 114 one by one from bottom to top, reducing the exercise intensity, rotates the screw 114 to move downward, and the weight plates 113 are connected to the screw 114 one by one from top to bottom, increasing the exercise intensity, and adjusting the exercise intensity to adapt to athletes with different conditions. After adjusting the exercise intensity, close the box cover 112, and then take the strap 116 out of the storage box 15, and then wrap the strap 116 around the calf, and stick the Velcro male buckle 117 on the Velcro female buckle 118, tie the strap 116 to the calf, and the athlete stands on the buffer plate 122, Then the athlete jumps up and pats the touch bar 9 with his hands to perform touch height training. The touch bar 9 is reset under the action of the first elastic member 10. After the athlete jumps up, the counterweight plate 113 is pulled upward by the pull rope 115. The counterweight plate 113 moves upward and contacts the contact rod 1211, and pushes the contact rod 1211 to move upward. The contact rod 1211 pushes the movable plate 129 to move in the direction away from each other. The movable plate 129 drives the wedge plate 124 to move in the direction away from each other. The third elastic member 125 is compressed, and the wedge plate 124 no longer blocks the buffer plate 122. When the block 126 corresponds to the slot, the block 126 moves upward and is inserted into the slot under the action of the fourth elastic member 127, and the wedge plate 124 is stuck. The block 126 pushes the inclined block 128 , so that the inclined plane blocks 128 move in the direction of approaching each other, then the athlete lands, the pull rope 115 is relaxed, the counterweight plate 113 moves downward under the action of its own weight, the push rod 1210 and the contact rod 1211 move downward under the action of their own weight, and then the athlete contacts the buffer plate 122, so that the buffer plate 122 moves downward, and the second elastic member 123 is compressed, so as to buffer the athlete and reduce the injury to the athlete's knee joint. The buffer plate 122 moves downward and contacts the inclined plane block 128, and then the buffer plate 122 pushes the inclined plane block 128 to move in the direction of moving away from each other, and the inclined plane block 128 pushes the card block 126 to move downward, the fourth elastic member 127 is compressed, and the card block 126 moves out of the card slot, and the wedge plate 124 is released.The wedge plates 124 move towards each other under the action of the third elastic member 125, and then the buffer plate 122 moves upward under the action of the second elastic member 123, and the buffer plate 122 contacts the wedge plate 124, and the buffer plate 122 pushes the wedge plate 124, so that the wedge plates 124 move away from each other. When the third elastic member 125 is compressed and the buffer plate 122 passes over the wedge plate 124, the wedge plate 124 moves towards each other under the action of the third elastic member 125, and the wedge plate 124 blocks the buffer plate 122, so that the buffer plate 122 cannot move downward again, thereby preventing the athlete from falling due to the repeated up and down movement of the buffer plate 122.

[0042] Embodiment 2: Based on embodiment 1, Figure 1 and Fig.12 As shown, it also includes a magnetic attraction mechanism 13, which includes a first magnetic attraction block 131, a slide bar 132, a fifth elastic member 133 and a second magnetic attraction block 134. The first magnetic attraction blocks 131 are connected to the left and right sides of the touch rod 9, and slide bars 132 are slidably provided on the left and right sides of the bottom of the connecting frame 7. The slide bar 132 can slide up and down in the connecting frame 7. A fifth elastic member 133 is connected between the front side of the slide bar 132 and the bottom of the connecting frame 7. The fifth elastic member 133 is a spring. The front side of the slide bar 132 is evenly spaced with second magnetic attraction blocks 134. The number of the second magnetic attraction blocks 134 is the same as the number of the first magnetic attraction blocks 131. The second magnetic attraction blocks 134 are used to adsorb the first magnetic attraction blocks 131.

[0043] When the athlete jumps up and hits the touch bar 9, the touch bar 9 rotates, so that the first magnetic block 131 approaches the second magnetic block 134, and the second magnetic block 134 attracts the first magnetic block 131, so that the touch bar 9 cannot be reset, which is convenient for the athlete to understand his or her own touch height score. The slide bar 132 is pulled downward, and the fifth elastic member 133 is stretched. The slide bar 132 drives the second magnetic block 134 to move downward. The second magnetic block 134 and the first magnetic block 131 are not in contact, and the first magnetic block 131 is no longer attracted. The touch bar 9 is reset under the action of the first elastic member 10, and then the slide bar 132 is released, and the slide bar 132 moves upward under the action of the fifth elastic member 133.
