[0043] When the first nut and the second nut move to the extreme position, a sudden stop will generate a certain inertia, which will produce a certain load on the entire device and affect the stability of the device. By setting a limit belt with elastic buffering capacity to buffer the inertial force, the device can operate more stably.
