Description of the new type: [Technical field to which the new type belongs] This creation relates to a wheel seat body with a brake device, especially a depression of the pedal to swing the brake pads in a rocker-type manner, and at the same time stop the wheel and the wheel seat body from moving. The wheel seat body, and the integrally formed brake pad can be quickly assembled on the eccentrically supported wheel seat body, which is suitable for various types of wheel seat bodies. [Previous technology] The invention of wheels made civilization drive from foot force into the era of mechanical rolling. The applications seen so far, such as passenger cars, trucks, connected cars, etc., have a wide range and far-reaching effects, especially the wheels of small wheel diameter are clever. Used in push-type mechanical structures such as strollers and baby strollers, they are more common around life and bring a lot of convenience to life. The wheel base of the small wheel diameter is often combined with the brake device to provide braking and fixing functions. Especially the rotary wheel structure can be moved or rotated. The brake device must be simultaneously or separately to prevent the wheel from rotating and not moving. For example, the patent of the Republic of China Announcement No. 5 7 8 7 0 "Rotary Wheel Improvement" provides a straight positioning device and brake device that can simultaneously or separately fix the rotation and movement of the wheel seat. However, in terms of mechanical design, this The structure of the device is still too complicated, with many parts, which results in high production costs, manufacturing costs and inventory costs. Therefore, there is an urgent need for a brake device that can reduce parts and simplify operations. Another example is the United States of America, which was applied for on October 7, 1988 by Sc re en Patent No. 4,941,552 "CASTOR WIT H B'RAKE MECHANISM" discloses a wheel seat body with a brake mechanism. If the brake pads are to be fixed on the seat body in a spanning manner, it is bound to require the cooperation of other detachable parts, which cannot be fast at once. The assembly is completed. Similarly, M279516 will increase the production cost and the assembly procedures are numerous. Because of this, the inventor of this creation has accumulated many years of manufacturing and production experience in this field, and tried various mechanical structures, which will bring the above-mentioned shortcomings to the birth of this creation. One by one [new content] The main purpose of this creation is to provide a wheel seat body that can be braked simultaneously and quickly, and its brake pads can be quickly assembled on the wheel seat body, which simplifies the assembly process significantly, reduces production costs, and is suitable for various types. Small wheel diameter wheel seat body The secondary purpose of this creation is to provide a wheel seat body with a simple operation and quick catch, which has a brake device, so that the user can easily make the wheel rotate and not move at the same time. _ In order to achieve the above-mentioned purpose, the car with a brake device of the present invention includes a seat on a rotating shaft for supporting and arranging a wheel seat, and a bottom plate is provided with a toothed disc; a base, which The utility model comprises a cover body, a shaft seat and an eccentric support body supported between the cover body and the shaft seat. The upper part of the cover body is pivoted with the rotating shaft, and a long hole is provided on the rear side. The upper end of the eccentric support body is deviated from the lower part of the cover body. The central axis is connected, and the lower end is connected with the shaft seat. A convex column is protruded laterally from the upper support section of the eccentric support body, and a convex rib is protruded from the lower support section at a proper position. A pedal for stepping has a lateral axis. A perforation is provided for pivoting in the long hole of the cover body; a brake pad with an arc, a front end of which is provided with a locking tab, and a middle concave portion is provided with an upper concave portion for laying on the convex column of the eccentric support body, Make the brake pad swing up and down with the convex column as a fulcrum, and extend at least one wing in the rear section; M279516 a return spring, one end of which is against the brake pad, and the other end is connected with a
