When the first motor 15 rotates, the support sleeve 17 is driven to move downwards in the sliding hole 19, so that the upper end of the support sleeve 17 is not in contact with the pedal 5, and a gap is generated between the support sleeve 17 and the pedal 5. After the player steps on the pedal 5, the pedal 5 can move downward. The first spring 23 is compressed, the first hinge 25 and the second hinge 26 rotate, and the striking member 31 of the first hinge 25 strikes the sound board 30, thereby alerting the player that the timer 1 of the starting point is in place. The firing contact 34 on the second hinge member 26 and the receiving contact 33 on the receiver 32 are able to make contact and when the pistol is fired, the firing contact 34 and the receiving contact 33 disengage and a timer is started. The signal is sent to the timer 1 of the endpoint and to the referee terminal. The timer 1 at the end point is that after the player steps on, the transmitting contact 34 contacts with the receiving contact 33, so as to realize timing, and then sends a signal to the referee terminal.

The cushion module 4 includes a second motor 35 and a second support base 36. The second motor 35 is provided with a second lead screw 351, the second support seat 36 is mounted on the second lead screw 351, the second support seat 36 is provided with a second height limiting rod 37 and a second spring 38, the second spring 38 is sleeved outside the second height limiting rod 37, and the second support seat 36 is further provided with a first limiting rod 361.

The second lead screw 351 is provided with a third lead screw 352, the third lead screw 352 is provided with a movable base 39, the movable base 39 is provided with a pulling piece 40, one end of the pulling piece 40 is hinged on the movable base 39, the other end of the pulling piece 40 is provided with a roller 41, and the movable base 39 is also provided with a second limiting rod 42. The pitch of the second lead screw 351 is greater than the pitch of the third lead screw 352, and the diameter of the second lead screw 351 is greater than the diameter of the third lead screw 352.

The pedal 5 has a notch 43 inside, a displacement groove 44 is formed on one side wall of the notch 43, the roller 41 is disposed in the displacement groove 44, the displacement groove 44 includes a pulling portion 441, a guiding portion 442 and a buffering portion 443, and the guiding portion 442 connects the pulling portion 441 and the buffering portion 443.

When the buffering module 4 is started, the second motor 35 can drive the second supporting seat 36 on the second lead screw 351 to move upwards, so that the second spring 38 contacts with the lower end face of the pedal 5 to support the pedal 5, and the buffering member 6 at this time can also be unfolded upwards. Meanwhile, the third screw 352 also rotates to drive the second limiting rod 42 on the moving seat 39 to move upward, and the second supporting seat 36 and the moving seat 39 cannot rotate and only move upward due to the limitation of the first limiting rod 361 and the second limiting rod 42. The pulling member 40 is not in the pulling portion 441 any more, but enters the buffering portion 443 along with the guide portion 442. Since the pitch of the second lead screw 351 is greater than that of the third lead screw 352, the second support seat 36 can move faster than the moving seat 39, so that the second spring 38 contacts the pedal 5 first. When the second motor 35 rotates reversely, the second spring 38 will be disengaged from the pedal 5, and then the pulling member 40 is introduced into the pulling portion 441 to pull the pedal 5 downward, so that the pedal 5 is placed on the third height-limiting rod 10 and flush with the bottom surface of the runway. The timer 1 when activated is a little higher than the bottom of the track, which facilitates the identification of the competitor.

When the started timer 1 is stepped on by the player, the roller 41 moves in the buffer portion 443 without affecting the displacement of the pedal 5, and the second spring 38 is compressed.

When training personnel need training or competition, a starting device is added on a pedal 5 on the starting timer 1, after the competition personnel are separated from the starting device, the starting timer 1 is separated from the starting timer, the starting timer 1 can start working, a timing function is started, the signal is transmitted to the ending timer 1 through a wireless transmission system, the signal can also be transmitted to a judge terminal, and the judging terminal can control the starting timer 1 and the ending timer 1. After the competition personnel have reached the key point, the competition personnel just can trample on the time-recorder 1 of terminal point, thereby trigger the switch of terminal point time-recorder 1 through trampling of competition personnel, note the time when trampling to realize the timing to the competition personnel. Without seeking the help of other people, the training or the competition can be independently completed. The training time is saved, the training effect is improved, and meanwhile the training time of other personnel is not delayed.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
