[0030] As shown in Figure 4 and Figure 5 As shown, the brake assembly 35 comprises a brake gear groove 351 opened on the outer surface of the universal wheel 32, the outer peripheral diameter size of the brake gear groove 351 is smaller than the outer peripheral diameter size of the universal wheel 32, the top of the brake gear groove 351 is engagedly connected with a brake gear 352, the inside of the brake gear 352 is sleeved with a connecting shaft 353, the cross section of the connecting shaft 353 is a horizontally arranged "arch" shape, a clock spring 354 is arranged between the brake gear 352 and the connecting shaft 353, the two ends of the clock spring 354 are connected with the brake gear 352 and the connecting shaft 353 respectively, and the two ends of the connecting shaft 353 penetrate through the brake gear 352 and are fixedly connected with the lower end of the linkage limiting carriage 342; due to the arrangement of the clock spring 354, under the limitation of the connecting shaft 353, the brake gear 352 can rotate within a certain range relative to the connecting shaft 353 under the elastic connection of the clock spring 354, and the elastic strength of the clock spring 354 is gradually increased, so that buffering is achieved, thereby avoiding the situation that the nursing vehicle frame 1 is overturned due to brake caused by too fast speed after the control assembly 4 is released.

[0031] The working principle and use process of the utility model are as follows:

[0032] While holding the handle 41, the two unlocking handles 45 are pulled tightly by both hands, so that the corresponding connecting ropes 36 are pulled at the same time under the cooperation of the limiting holes 43 and the communication clamping grooves 44, and then the connecting ropes 36 are pulled by the nursing vehicle frame 1, so that the linkage limiting carriage 342 is pulled to move upward along the inside of the limiting sleeve 341, and the positioning spring 344 is compressed to increase the elastic recovery strength under the cooperation of the positioning baffle 343;

[0033] Due to the upward movement of the linkage limiting carriage 342, the connecting shaft 353 can be driven to move upward, and then the brake gear 352 and the clock spring 354 in the brake gear 352 are driven to move upward as a whole, so that the brake gear 352 is separated from the brake gear groove 351, thereby removing the limitation on the universal wheel 32, and ensuring that the universal wheel 32 can rotate smoothly;

[0034] During the movement, once the user releases the unlocking handle 45, the linkage limiting slide 342 is pushed down by the elastic restoring force of the positioning spring 344, and then the brake assembly 35 is pushed down as a whole through the connecting frame, so that the bottom of the brake gear 352 is tightly engaged in the inside of the brake gear groove 351, and the brake gear 352 can rotate within a certain range to follow the universal wheel 32 under the elastic action of the clock spring 354, so as to achieve the buffering effect, and avoid the situation that the control assembly 4 is accidentally dropped and falls due to too high speed.
