When the brake mechanism 80 is not provided, when the load W is suspended and the teeth of the winding wheel 411 are broken, the teeth of the winding wheel 411 cannot mesh with the driving wheel 231 of the reduction gear set 23, and at this time, the weight of the load W causes the winding wheel 411 to rotate at a high speed (or stall), and the conveying belt 413 is rapidly released, so that the load W falls under the acceleration of gravity.

Through the arrangement of the brake mechanism 80, teeth are broken at each tooth of the tape wheel 411, when the tape wheel 411 rotates at a high speed, the rotating centrifugal force of the tape wheel 411 is larger than the elastic tension of the tension spring 82, the brake pad 83 can not be pulled by the tension spring 82 and is thrown away from the outer side (as shown in fig. 10), the thrown brake pad 83 rotates along with the tape wheel 411 in the counterclockwise direction until the brake pad 83 touches the clamping column 81, and the tape wheel 411 can not rotate continuously, thereby achieving the purpose of braking.
