as shown in fig. 4 and 5, the gyro toy of the first embodiment includes: a gyro body 1, a gyro shaft 2, a rotary sleeve 3, and a gyro gear 5. The gyro body 1 is approximately bowl-shaped, a shaft sleeve 13 is downwards extended from the middle of the lower end of the gyro body 1, the shaft sleeve 13 is a cylinder 23 with the same diameter, the diameter is slightly smaller than the aperture of the rotary sleeve body 3, a circle of grooves 131 are formed in the middle of the shaft sleeve 13, at least two elastic buckling feet 32 are uniformly distributed on the inner ring wall of the corresponding rotary sleeve body 3, during assembly, the rotary sleeve body 3 is sleeved below the shaft sleeve 13, at the moment, the elastic buckling feet 32 are extruded by the outer wall of the shaft sleeve 13 to radially outwards elastically deform until the elastic buckling feet 32 move to the positions of the grooves 131, the elastic buckling feet 32 elastically reset and are clamped into the grooves 131, so that the rotary sleeve body 3 and the shaft sleeve 13 are axially connected in a positioning mode, meanwhile, the rotary sleeve body 3 can rotate relative to the shaft sleeve 13, and the elastic buckling feet 32 rotate in the grooves 131 during rotation of the rotary sleeve body 3. The upper end edge of the rotating sleeve body 3 outwards extends along the radial direction to form a circular convex edge 31, a convex point 15 is arranged on the bottom surface of the gyro body 1 towards the direction of the circular convex edge 31, the tip end of the convex point 15 is in contact with the upper surface of the circular convex edge 31, the contact area is small, so that the friction force is greatly reduced, and when the gyro emitter rotationally accelerates the gyro, the gyro body 1 cannot cause the rapid reduction of the rotating speed due to overlarge friction force between the gyro body 1 and the rotating sleeve body 3, namely, the friction loss of the gyro body 1 is smaller when the gyro body rotates relative to the rotating sleeve body 3, so that the rotation of the gyro is more durable.

The connecting column 21 of the gyro shaft 2 in this embodiment is designed as a hexagonal column, a screw hole 25 is provided at the end face of the connecting column 21, the through hole 14 in the middle of the gyro housing 11 is a hexagonal hole, the connecting column 21 passes through the through hole 14 from below the through hole 14, and then a screw 6 with a nut is screwed onto the screw hole 25, so that the nut part of the screw 6 is abutted against the periphery of the through hole 14 of the gyro housing 11; the top shaft 2 also has a shaft post 22 portion, which shaft post 22 portion is for fixed connection with the top gear 5. Unlike the first embodiment, the third part of the gyro shaft 2, i.e. the part under the shaft post 22, is also a cylinder 23, but the diameter of the cylinder 23 is larger and only slightly smaller than the outer diameter of the rotary sleeve 3, and the bottom of the lower end is folded towards the middle to form a tip, i.e. the top 24. The third portion of the gyro shaft 2 is designed so that the gap between the third portion and the lower portion of the holding opening of the gyro emitter is reduced by the third portion, the upper portion of the holding opening of the gyro emitter is held in cooperation with the rotary sleeve body 3, and the output gear is located in the middle of the holding opening, so that the lower portion of the gyro shaft 2 may shake when the gyro toy is driven to rotate by the gyro emitter, and the whole gyro is thereby shaken, and the third portion is provided with a larger diameter, so that the third portion abuts against the wall surface of the lower portion of the holding opening when the gyro toy is shaken, and the gyro toy is restricted from shaking.

When in assembly, the rotary sleeve body 3 is connected and fixed with the shaft sleeve 13; then, the gyro gear 5 passes through the connecting column 21 from the upper part of the gyro shaft 2 and then is tightly sleeved on the shaft column 22 in a hard extrusion mode, so that the gyro gear 5 is fixedly connected with the gyro shaft 2; finally, the connecting column 21 of the gyro shaft 2 is matched and connected with the through hole 14 of the gyro main body 1, so that the whole gyro toy can be assembled. The gyro structure is simpler, and the top 24 is a tip, so the durability of rotation is stronger.

According to the embodiment, the rotating sleeve body 3 is rotatably connected to the gyro main body 1, so that the clamping force of the gyro emitter on the gyro is acted on the gyro main body 1, and the power output of the gyro emitter is transmitted to the gyro gear 5 of the gyro shaft 2, so that two acting forces are respectively dispersed on the gyro main body 1 and the gyro shaft 2, uniform stress is ensured, the influence of the acting forces on the gyro shaft 2 is reduced, the coaxiality of all parts of the whole gyro is improved, and the rotating quality of the gyro is further improved; the rotating sleeve body 3 and the gyro gear 5 have enough gaps, the height of the rotating sleeve body 3 is not greatly limited, and the upper edge of the rotating sleeve body 3 is provided with the circular convex edge 31, so that the gyro emitter is not easy to touch the gear or the gyro main body 1 when recovering and clamping the spinning top, and the phenomenon of incomplete clamping is avoided, so that the rotating speed of the gyro is not weakened or stopped, and the playing effect is better; further, since the protruding points 15 are provided on the bottom surface of the gyro body 1 to reduce the rotation friction, the friction loss between the gyro gear 5 and the gyro body 1 is small when the gyro gear and the gyro body 1 rotate relative to the rotary sleeve 3, and the rotation of the gyro can be made longer.
