[0060] The method of playing the decompression fidget spinner provided by the utility model is as follows:

[0061] 1. Opening mode: Without placing the gravity stick, the lower piece 1 faces downward, and the right hand holds it. The thumb rotates the upper piece 2 clockwise, the ring finger rotates the lower piece 1 clockwise, or the index finger and middle finger move the middle body counterclockwise. At this time, under the limit of the hemispherical 30° arc groove, the upper and lower pieces rotate 60° relative to the middle body 3, and the fingertip gyroscope is opened from three petals to six petals, that is, the upper and lower pieces have three petals, and the middle body has three petals; before the upper and lower pieces rotate, the magnets in the fourth circular groove 26 and the sixth circular groove 36 attract and lock each other, and after the upper and lower pieces rotate, the magnets in the second circular groove 16 and the sixth circular groove 36 attract and lock each other; when the outer side of the lower piece 1 faces upward, the clockwise and counterclockwise directions are opposite, and the principle is the same;

[0062] 2. Centrifugal rotation mode: without placing the gravity stick, press the two end covers of the locking structure 4 by hand, and move the whole structure to rotate as a whole, and the centrifugal block slides out, either forward or reverse; if the nail is opened and rotated at high speed, when the upper and lower pieces stop rotating suddenly, the nail piece can be automatically closed under the action of the magnet;

[0063] 3. Left and right hand mode: A gravity stick is placed in the first through hole 51 and the second through hole 52. When the through hole for placing the gravity stick faces upward, the gravity stick completely falls into the middle plate 31 under the action of gravity, without affecting its open armor mode or centrifugal rotation mode; when the through hole for placing the gravity stick faces downward, the gravity stick falls into its corresponding upper piece 2 or lower piece 1 under the action of gravity. Since its length is greater than that of the upper piece 2 or the lower piece 1, one end of the gravity stick will remain in the middle plate 3. Therefore, the upper and lower pieces and the middle body 3 will be locked and cannot rotate, reminding the player to flip the gyroscope over; the purpose of the gravity stick design is that it can be adjusted so that the fingertip gyroscope can be played with both the right hand and the left hand to satisfy all players.
