The working principle of the invention is as follows: in an initial state, the first connecting rod 12 and the second connecting rod 13 are in a vertical state, a dead point mechanism is formed under the action of the spring 11, and at the moment, the first connecting rod 12, the second connecting rod 13 and the shaft lever 5 on the sliding plate 3 support the supporting rod 6 and keep the supporting rod 6 in a vertical state;

when the athlete is hurdling, the athlete slightly touches the rail 8 to enable the half rods to be stressed to generate torsional motion, so that the two half rods are separated and avoided to avoid the athlete, the athlete is prevented from tripping over, the half rods are twisted and the tension springs 16 are stretched or twisted at the same time, so that the tension springs 16 obtain restoring force or torque for enabling the half rods to restore to the initial state, and after the touch is finished, the restoring force or torque on the tension springs 16 enables the half rods to restore to the initial state, so that the safety of the athlete can be ensured, the frequency of manually supporting the supporting rod 6 is reduced, the efficiency is improved, and the labor cost output and the labor intensity are reduced;

when the athlete has a large touch force on the rail 8 or the support rod 6, as shown in fig. 1 and 2, the support rod 6 is forced to rotate counterclockwise around the shaft rod 5, and the pin shaft connected with the lower end of the first connecting rod 12 and the support rod 6 is taken as a fulcrum, and also performs counterclockwise rotation motion around the fulcrum, the support rod 6 drives the sliding plate 3 to move up along the bracket 2 while rotating, when the center height of the pin shaft connected with the first connecting rod 12 and the support rod 6 is lower than the center height of the pin shaft connected with the third connecting rod 14 and the support rod 6 (namely, the connection point of the third connecting rod 14 and the support rod 6 is located on the right side of the dotted line in fig. 2), the dead point position between the first connecting rod 12 and the second connecting rod 13 is damaged by the force applied by the support rod 6 to the first connecting rod 12, so that the second connecting rod 13 rotates clockwise around the connection point of the second connecting rod 13 and the support, the impedance effect on the athletes is eliminated, and the athletes are prevented from tripping, so that the safety is improved;

after the supporting rod 6 is turned over, need the manual work to hold it up to the initial position, during the operation, lift the supporting rod 6 and make the supporting rod 6 rotate clockwise around axostylus axostyle 5, the clockwise rotation of supporting rod 6 drives connecting rod three 14 and rotates anticlockwise around the junction of connecting rod three 14 and branch 15 on support 2 right side simultaneously, the bracing piece 6 drives the contained angle increase between connecting rod one 12 and the connecting rod two 13 simultaneously, and tend to a vertical line, when connecting rod one 12 and connecting rod two 13 are in same straight line, spring 11 this moment, connecting rod one 12 and connecting rod two 13 reset, connecting rod two 13 is in the dead position, the tie point of connecting rod three 14 and supporting rod 6 is located the left side of dotted line in figure 1, slide 3 resets and moves to the initial position simultaneously, form the.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
