the upper end of the transition seat (71) is provided with a rotating shaft (711) through two holes, the right-angle position of the L frame (712) is installed on the rotating shaft (711), and the L frame (712) rotates by taking the rotating shaft (711) as a shaft;

the position of the half gear (34) on the connecting strip (33) and the position of the connecting strip (33) on the transmission bracket (31) can be adjusted, and the position is used for adjusting the elasticity of the coil spring and the revolution acceleration of the half gear (34);

wherein, this special apparatus's for football training working method includes following step:

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.
