When braking, the second pressing piece applies pressure to the abutting part, so that the deceleration pad abuts between the abutting part and the middle part of the hub part, and the braking process is realized by utilizing the friction force generated by the surfaces of the two surfaces of the deceleration pad, which are respectively contacted with the abutting part and the hub part.
Therefore, the utility model discloses following beneficial effect can be reached: the process of clutching and braking is realized simultaneously by applying pressure, so that the control process is more convenient and faster; because the two sides of the deceleration gasket generate friction resistance at the same time, the deceleration gasket in pairs is avoided being used at the same time, and the number of parts is reduced.
Preferably, the elastic shaft is a fixed shaft sleeved with a spring, one end of the spring abuts against the abutting part, and the other end of the spring abuts against the second pressing piece.
Preferably, the elastic shaft is fixedly connected with the middle shaft in a manner that: the fixed shaft is embedded in the middle shaft and is in threaded connection with the middle shaft.
Preferably, the middle part of the hub part is a cavity, and the deceleration pad is abutted to the inner part of the cavity by the elastic pressing piece, so that the occupied space is reduced, and the structural parts of the toy are simpler and more attractive.

Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Example 1
A speed reducer of a hub unit for a toy is provided to be mounted on a wheel of a toy vehicle 100. Specifically, the hub comprises a hub part 1, a speed reduction gasket 2, a butting part 3 and an elastic pressing part 4, wherein a middle shaft 10 is arranged in the middle of the hub part 1, and the speed reduction gasket 2 is sleeved on the middle shaft 10 and butts against the middle part of the hub part 1; the abutting part 3 passes through the middle shaft 10 and is abutted against the deceleration pad 2 by the elastic pressing piece 4; the elastic pressing piece 4 comprises an elastic shaft 41, a first pressing piece 42 and a second pressing piece 43, the elastic shaft 41 is fixedly connected with the middle shaft 10, the first pressing piece 42 and the second pressing piece 43 respectively penetrate through the elastic shaft 41, a flange 421 extending towards the direction of the second pressing piece 43 is arranged on the first pressing piece 42, and a concave part 431 matched with the flange 421 is arranged on the second pressing piece 43; when the elastic shaft 41 is compressed, the first pressing piece 42 approaches the second pressing piece 43, and the flange 421 abuts against the recess 431; the abutting part 3 comprises a cavity, the second pressing piece 43 is arranged in the cavity of the abutting part 3 and is fixedly connected with the first pressing piece 42; the spring follower 4 is used to connect to the toy 100.
