The wrist power ball is a manual power device, is purely mechanical, does not need batteries or any power supply, and drives the ball center to rotate at high speed by the rotation of the wrist, thereby generating strong power. The wrist power ball continuously rotates under the action of the gyroscope and the angular momentum to generate strong power. Has promoting effect on exercising strength and toughness of fingers, wrists and arms. For middle-aged and elderly people, it is helpful for promoting blood circulation, preventing cardiovascular and cerebrovascular diseases, and delaying aging. For young people, the hand-held trainer is beneficial to promoting the growth of bones and the development of brains, enhancing the grip strength and the wrist strength of both hands and exercising the flexibility of fingers.
At present, three starting modes are rope starting, double-hand starting and single-hand starting. The rope starting method needs to tightly wind the rope in the central groove of the center of the sphere and then quickly pull out the rope to start the wrist power ball, and the method needs to use the rope and is complex to operate. The two-hand starting method needs to use the thumb to stir the centre of the ball towards the central groove to wind the wrist power ball. The single-hand starting method needs to hold the wrist power ball with the opening part facing upwards, quickly stir the center of the ball along the direction of the central groove of the center of the ball by the thumb, and randomly start the wrist power ball with the opening part facing downwards after reaching a certain speed. The three starting methods are complex, and the rope starting method is more inconvenient by means of a starting rope. Moreover, the three starting methods need a certain technical basis for operation, and users without the basis are easy to have insufficient winding of a clockwork spring and insufficient rotation speed of the center of sphere, so that starting cannot be performed.

Preferably, the upper shell and the transition ring are connected through a concave-convex spigot; the transition ring is connected with the lower shell through a spigot and a screw.
The lower case 430 is formed inside with a cylindrical fixing structure 431, and the top of the cylindrical fixing structure 431 is formed with a fixing groove, in which the swivel ring 112 is fitted and allowed to swivel.
The two ends of the central shaft 111 of the center 110 are respectively pivoted to the pivot holes of the rotary ring 112, so that the center is accommodated in the hollow spherical shell formed by the upper shell 410, the lower shell 430 and the transition ring 420.

Preferably, the rectangular opening of the outer support ring 211 coincides with the rectangular opening of the transition ring 420; the actuation button 421 is embedded in the rectangular opening and protrudes from the outer surface of the transition ring 420. At this time, the internal gear 212 may be rotated by pushing the start button 421.
An upper support shaft 218 and a lower support shaft 219 are arranged on the inner side surface of the outer support ring 211, a transmission gear 217 is arranged on each support shaft of the outer support ring, and the inner gear 212 is meshed with the transmission gear 217.

That is, when pushing the start button 421 is finished, the upper housing 410 is rotated clockwise, the internal gear formed by the mechanical iris inner ring unit 320 is driven by the connecting rod to rotate clockwise, and then the first bevel gear 122 is driven to rotate clockwise, so that the winding gear 124 is driven to rotate forward, and the winding spring realizes energy storage. At this time, if the start button 421 is pushed back to the initial position, the rotation ring 112 is out of the limit, the energy stored in the spring 121 is released instantaneously, the ratchet 125 drives the center of the sphere to rotate through the pawl 113, the device is shaken, the rotation ring 112 rotates on the fixed groove, the center of the sphere 110 continues to rotate due to the corrected angular momentum, and the wrist ball starts.
Therefore, the wrist power ball is started by using a smart mechanical structure, and the ball center of the wrist power ball is completely arranged in the shell, so that the risks of clothes rolling and skin abrasion are eliminated. In addition, the starting mode of the wrist strength ball is simple and friendly to novice, the wrist strength ball can be started only by pushing the button, rotating the shell and pushing the shell back, and the probability of failure in starting the wrist strength ball is greatly reduced. The shell of the product is of an up-and-down symmetrical structure and is formed with beautiful arcs, and can be used as a decoration when not in use
