[0028] Further, such as Figure 2 As shown, the feeding assembly 6 includes two pillars 601, the bottom ends of the outer surfaces of the two pillars 601 are fixedly connected to the upper end of the outer surface of the shell 2, the upper ends of the two pillars 601 are fixedly connected to a storage pocket 602, the right bottom of the storage pocket 602 is fixedly connected to a connecting column 603, the right end of the inner surface of the shell 2 is fixedly connected to a ramp 604, and the inner surface of the connecting column 603 is provided with a hole that penetrates the storage pocket 602 and the inner surface of the shell 2.

[0029] Furthermore, by providing a hole on the inner surface of the connecting column 603 that penetrates the storage pocket 602 and the inner surface of the shell 2, the football goalkeeper can fill the ball independently after receiving it.

[0030] Further, such as Figure 3 and Figure 6 As shown, the launch adjustment assembly 3 includes a support plate 303, both ends of the support plate 303 are fixedly connected to the inner surface of the shell 2, the middle part of the support plate 303 is rotatably connected to a rotating rod 302, one end of the rotating rod 302 passes through the inner surface of the shell 2 and is fixedly connected to a hand wheel 301, the left end of the rotating rod 302 is fixedly connected to a turntable 304, the outer surface of the turntable 304 is fixedly connected to teeth 305, the lower left end of the shell 2 is fixedly connected to a circular tube 307, the inner surface of the circular tube 307 is rotatably connected to a friction pad 308, and the right end of the outer surface of the friction pad 308 is fixedly connected to a rotating gear 306.

[0032] like Figure 4 As shown, the rotating component 4 includes a protective shell 401, the bottom end of the protective shell 401 is fixedly connected to the top of the shell body 2, the top of the inner surface of the protective shell 401 is rotatably connected to a transmission column 1 403, the upper part of the outer surface of the transmission column 1 403 is fixedly connected to a transmission gear 1 402, the lower part of the outer surface of the transmission column 1 403 is rotatably connected to a transmission column 2 406, the top of the outer surface of the transmission column 2 406 is fixedly connected to a transmission gear 3 405, and the output end of the motor 7 passes through the front end of the outer surface of the protective shell 401 and is fixedly connected to the transmission gear 2 404.

[0033] Furthermore, by setting the output end of the motor 7 to be fixedly connected to the transmission gear 2 404 , when the motor 7 rotates, the transmission gear 1 402 and the transmission gear 3 405 are driven to rotate in opposite directions through the transmission gear 2 404 fixedly connected to the output end.

[0034] Further, such as Figure 4 As shown, a pulley 501 is fixedly connected to the bottom of the outer surface of the transmission column 1 403 , and a power wheel 503 is fixedly connected to the bottom of the outer surface of the transmission column 2 406 .

[0035] It can be seen that the motor 7 drives the two transmission gears 1 402 and 405 meshing with the transmission gear 2 404 to rotate in opposite directions, while causing the transmission column 1 403 fixedly connected to the middle part of the inner surface of the transmission gear 1 402 to rotate, and the transmission gear 3 405 rotates while driving the transmission column 2 406 to rotate.

[0036] like Figure 5 As shown, the launching assembly 5 includes a rotating column 508, the bottom wall of the rotating column 508 is rotatably connected to the rear part of the bottom wall of the inner surface of the shell 2, the top of the rotating column 508 is fixedly connected to the pulley 2 504, the pulley 2 504 and the pulley 1 501 are commonly wound with the belt 1 502, and the belt 1 502 is wound together by the pulley 2 504 and the pulley 1 501 so that the pulley 1 501 can drive the pulley 2 504 to rotate while rotating, and a rotating column 1 507 is rotatably connected to the front part of the bottom wall of the inner surface of the shell 2, the upper end of the upper outer surface of the rotating column 1 507 is fixedly connected to the transmission wheel 2 506, the transmission wheel 2 506 and the power wheel 1 503 are commonly wound with the belt 2 505, and the lower parts of the outer surfaces of the rotating column 1 507 and the rotating column 2 508 are fixedly connected.

[0037] By winding the belt 1 502 around the pulley 2 504 and the pulley 1 501 together, the pulley 1 501 can drive the pulley 2 504 to rotate while rotating.

[0038] The working principle of the utility model is as follows: first, the goalkeeper rotates the hand wheel 301 to drive the turntable 304 fixedly connected to the left end of the outer surface of the rotating rod 302 to rotate, and the turntable 304 meshes with the rotating gear 306 through the teeth 305 fixedly connected to the outer surface, thereby further adjusting the position of the friction pad 308 connected to the inner surface of the circular tube 307. After the friction pad 308 is adjusted to a suitable angle, the motor 7 is turned on. At this time, when the motor 7 is rotating, the transmission gear 2 404 fixedly connected to the output end and the transmission gear 306 are engaged. The first wheel 402 is meshed with each other to make the transmission column 1 403 rotate. When the transmission column 1 403 rotates, it further drives the power wheel 1 503 at the bottom to rotate. By setting a belt 2 505 in the middle of the power wheel 1 503 and the middle of the transmission wheel 2 506 for winding connection, the power wheel 1 503 drives the lower friction wheel 509 on the outer surface of the rotating column 1 507 to rotate while rotating. By setting a transmission gear 3 405 on the upper end of the transmission column 2 406 and the transmission gear 2 404 fixedly connected to the output end of the motor 7 The two symmetrically arranged friction wheels 509 are engaged with each other, so that the transmission column 406 rotates and drives the pulley 501 to rotate at the same time. By setting a belt 502 to be wound and connected between the pulley 501 and the pulley 504, the pulley 501 drives the friction wheel 509 fixedly connected to the lower part of the outer surface of the rotating column 508 to rotate at a high speed. When the two symmetrically arranged friction wheels 509 rotate at a high speed, the goalkeeper throws the football into the inner surface of the storage pocket 602, and the inner surface of the storage pocket 602 is inclined so that the football slides into the connection The inner surface of the column 603 further slides between the two high-speed rotating friction wheels 509 through the inclined platform 604, and the two friction wheels 509 rotate at high speed to drive the football to fly out. During the flying process of the football, the friction pad 308 connected by the rotation of the inner surface of the circular tube 307 makes the football rotate during the flight. Due to the unbalanced air resistance on both sides, the friction difference makes the football produce a rotation component in the horizontal direction, thereby making the football produce an arc. Then the goalkeeper throws the picked up football into the storage bag 602 to complete the personal training.
