Each extending arm and the corresponding connecting arm form a hinge joint; when each group of connecting arm assemblies is in the traction state through cooperation, each extending arm can adjust the angle by rotating, driving each roller to be evenly distributed on the surface of the top of the football, and realizing multi-directional contact with the surface of the top of the football.

[0010] A further setting is that notches are formed at the ends of each of the connecting arms away from the body, the extension arms inside each of the rollers extend into the corresponding notches respectively, and a rotating shaft passing through the extension arms is arranged in the notches, so that the extension arms and the corresponding connecting arms form a hinge joint;

[0011] A servo motor is fixedly arranged on the connecting arm, the servo motor has an output shaft, a control block is fixedly arranged at the end of the output shaft of the servo motor, a controlled block is fixedly arranged on the extension arm, and the controlled block and the corresponding control block are fixedly connected by a connecting rod.

[0012] A further setting is that the connecting arm is composed of a first rod body and a second rod body, the straight line corresponding to the first rod body and the straight line corresponding to the second rod body have a predetermined angle, and the predetermined angle is greater than 90 degrees.

[0013] A further setting is that a plurality of protrusions corresponding to the positions of the connecting arms are fixedly arranged at the lower end of the body, each of the connecting arms is respectively hinged to the corresponding protrusion, through holes communicating with each other are formed between each of the connecting arms and the corresponding protrusion, and the corresponding connecting arm and the protrusion are fixed by arranging bolts in the through holes.

In the traction state, each group of connecting arm assemblies can hold the top of the football, and the football is pulled to roll along the ground, so as to interact with the football, thereby improving the efficiency and actual effect of football training.

[0017] 2. In the present utility model, the rollers at the ends of the connecting arms can not only endow the body with the function of moving on the ground surface, but also contact and hold the top of the football. The contact area between the rollers and the top of the football is small, which can effectively reduce friction, thereby reducing energy consumption and improving the flexibility of the body.

[0018] 3.
