step two: according to the length of the big arm of the training personnel, the limiting rod (142) is pulled to drive the cushion block (143) to extrude the spring (144), the limiting rod (142) slides out of the positioning hole (10), the big arm component (12) slides on the limiting block (9), the position of the big arm component (12) is adjusted according to the positioning hole (10) designed at equal intervals on the outer wall of the limiting block (9), so that the positions of the first fixing component (11) and the big arm component (12) are adjusted, and finally, the position of the big arm component (12) is limited through releasing the limiting rod (142) and matching between the limiting rod (142) and the positioning hole (10), so that the position of the big arm of the equipment is adjusted;
step three: according to training personnel forearm length, through spacing subassembly (14) of pulling third fixed subassembly (16) front side outer wall, make gag lever post (142) drive cushion (143) extrusion spring (144) and locating hole (10) in roll-off forearm subassembly (15) outer wall, locating hole (10) through equidistant setting of forearm subassembly (15) outer wall, adjust the position of third fixed subassembly (16), finally through releasing gag lever post (142), through the cooperation between gag lever post (142) and locating hole (10), inject the position of third fixed subassembly (16), thereby realize the regulation of equipment forearm
Step four: after the large arm and small arm are adjusted, the angle between the small arm assembly (15) and the large arm assembly (12) is adjusted by loosening the screw at the joint of the large arm assembly (12) and the small arm assembly (15), the angle of the large arm and the small arm is enabled to be the optimal training angle, the screw is finally screwed, the angle between the large arm assembly (12) and the small arm assembly (15) is limited, finally, the arm is fixed through the first fixing assembly (11), the second fixing assembly (13) and the third fixing assembly (16), and then the ball attack action training is carried out.
