Description of drawings

Fig. 1 is a structural schematic diagram of the present invention.

Detailed ways

The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

As shown in Fig. 1, the present invention includes a fixed sleeve 6 arranged symmetrically, pins 7 are installed on the outer peripheral surface of the fixed sleeve 6, and fixed cross bars 5 are connected between the fixed sleeves 6, and there are two fixed cross bars 5; A telescopic rod 2 is installed in the sleeve, and the telescopic rod 2 is provided with a pin hole 8. The top of the telescopic rod 2 is connected to the bracket 1, and a rotating rod 10 is placed on the bracket 1. The bracket 1 is "U" shaped, and the two ends of the bracket 1 are not connected. Contours can effectively protect trainers and prevent the rotating rod 10 from falling. One end of the wire rope 3 is wound on the rotating rod 10, the other end of the wire rope 3 is wound on the hook 9, and the hook 9 can be placed in the groove on the surface of the sphere (the groove on the surface of the sphere is not shown in Fig. 1), the weight of the sphere 1-7kg, suitable for people of all ages.

Working process of the present invention:

Training method 1: First loosen the pin 7, raise or lower the telescopic rod 2 to the required height, and then insert the pin 7 into the pin control 8 to fix the telescopic rod 2; In the vertical state, hold the rotating rod 10 with both hands, the trainer can rotate the rotating rod 10 with both hands, and the wire rope 3 is wound or loosened, so that the ball 4 rises or falls, so as to achieve the purpose of training the strength of the wrist or arm.

Training method 2: remove the ball 4 from the hook 9, the trainer grasps the ball 4 with his hand, releases his hand, and catches the ball when the ball 4 falls, which can achieve the purpose of training finger strength.

Training method 3: remove the sphere 4 from the hook 9, the trainer grasps the sphere 4 with his hands, and performs forearm flexion exercises, which can achieve the purpose of training the strength of the big arm.

Training method 4: take off the sphere 4 from the hook 9, the trainer grasps the sphere 4 by hand, and performs the exercise of stretching the arms on both sides of the straight body, which can achieve the purpose of training the strength of the shoulder triceps.

Training method 5: the ball 4 is removed from the hook 9, and the trainer performs repeated shoulder push (similar to the technique of throwing a shot put) practice, which can achieve the purpose of training arm strength.

The above description is an explanation of the present invention, not a limitation of the invention. For the limited scope of the present invention, refer to the claims. The present invention can be modified in any form without departing from the basic structure of the present invention. the
