Moreover, the limiting part 180 is arranged in a circular ring shape, which can also be used to install and guide the support rod 151 for sliding up and down. In order to prevent the support rod 151 from falling off, a limiting protrusion 190 with a diameter larger than the inner diameter of the limiting part is arranged at the upper end of the support rod 151 above the limiting part 180

[0052] The pitch and thread accuracy of the lead screw are strictly controlled to ensure that the inner tube 111 can move up and down accurately and stably under the drive of the lead screw, thereby realizing accurate adjustment of the length of the crutch.

[0053] The motor driving module and the DC motor are composed of a dedicated H-bridge motor driving chip, which can provide a driving current of up to 2A to meet the driving needs of the DC motor. The driving chip receives the PWM control signal sent by the main control MCU module, and accurately controls the speed and direction of the DC motor by adjusting the duty cycle of the PWM signal. The DC motor selects a micro motor with a torque of 10kg·cm, and the output shaft of the motor is connected with the crutch extension mechanical module through a gear transmission mechanism to realize the extension function of the crutch.
