Under the action of the coil spring box, the coil spring in the coil spring box also has elastic recovery force under the action of the rotation force, so that when the pedal is released, the compression spring gives a forward force to the simulated foot, and the coil spring gives the rack through the half-width gear A forward force acts on the simulated foot, so that the simulated foot has two superimposed forces before touching the football, which are jointly applied to the point of the football, so that the football has a huge kinetic energy instantly, and the football moves along the predetermined direction. Shot towards the goal.

2. The half-width gear has the function of stabilizing the launch. When the simulated foot hits the football and launches it, it will move backward under the reverse force of the compression spring. At this time, the elastic force of the coil spring pulls the half-width gear to make it It will not move backwards. Under the action of the elastic recovery force, the half gear can give the rack an acceleration. Because the center of gravity of the half gear is close to the side with the gear, it will generate an acceleration before it touches the football in the reverse direction, providing greater simulation for the foot. The kinetic energy; the two ring universal wheels and the two baffle universal wheels facilitate the movement of the training equipment. Give the device a fulcrum to keep it balanced and stable with two more fulcrums when it produces a huge impact.

3. The rubber pad set at the front end of the simulated foot has the elastic effect of simulating the human foot. Compared with the metal pop-up structure in the market, it is more in line with the actual scene, so that the moment the simulated foot touches the football due to the uneven force The flight trajectory is very different, so that it has more practical significance in the goalkeeper's defensive training, and it can better improve the goalkeeper's reaction speed in the case of uncertainty.

4. The present invention is mainly used for the training of the goalkeeper's ability to catch the ball. Under the double elastic force of the compression spring and the coil spring, the football is contacted under the unknown elastic force of the rubber pad, and different trajectory football shooting angles are produced, which can give the goalkeeper The training adds the uncertain factor of actual combat.

step one, transversely rolling a football collecting frame (1) to the front of a goal, laterally rolling a ball dispenser (2) for ninety degrees, downwards turning two baffle universal wheels (231) and two ring universal wheels (42), pushing the ball dispenser (2) to move to the goal position, reversely rolling the ball dispenser (2) for ninety degrees, aligning a ball stopping platform (22) to the goal position, and installing the football collecting frame (1) on the ball dispenser (2) and fixing the football collecting frame through an elastic fastener;

secondly, sequentially placing a plurality of football into the collecting holes above the football collecting frame (1), enabling the football to fall onto a ball stopping platform (22) in the spiral football collecting frame (1), and stopping the football on a ball dispenser (2) through a ball stopping baffle plate (23) in a balanced manner;

step three, the pedal (73) is stepped by a foot, the middle rod (61) is pulled backwards by the downward force of the pedal (73) under the action of the L-shaped frame (712) and the rotating shaft (711), the middle rod (61) rotates the first stabilizer bar (25) and the second stabilizer bar (26) through the hinged connection of the tail ends of the first pull rod (62) and the second pull rod (63), the first stabilizer bar (25) and the second stabilizer bar (26) are connected with the fixed ring (4) in a contact mode to keep the compression spring (41) stable, and the pull rod (54) is pulled to make the same linear movement under the action of the backward movement of the middle rod (61);

fourthly, the traction rod (54) moves to drive the rack (32) and the simulation feet (5) to move backwards at the same time, the rack (32) transmits linear motion to the half gear (34) to do circular motion, the half gear (34) rotates to drive the coil springs in the coil spring boxes (37) to have elastic restoring force, at the moment, the pedals (73) are loosened, the simulation feet (5) move forwards quickly under the action of the double elastic restoring force of the compression springs (41) and the coil springs, the surface of the front ends of the simulation feet (5) contacts with the football, and the football is popped up to fly to the goal;

and step five, the forward moving simulation foot (5) drives the traction rod (54) to move forward, so that the L-shaped frame (712) rotates reversely, and the pedal (73) returns to the highest position under the rolling action of the first roller (74), the second roller (75), the third roller (76) and the fourth roller (77) with smaller resistance.
