Title:
CASTER CONTROL APPARATUS AND ULTRASONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/051799
Kind Code:
A1
Abstract:
A caster control apparatus and an ultrasonic device. A device base (100), a pedal (400), a connecting rod (600) and driven pieces (500) form a linkage mechanism which is integrally linked to drive a first pawl (410) and a second pawl (510) to move, such that said pawls lock a first ratchet (310) and a second ratchet (320) respectively. When unlocking is required, the first ratchet and the second pawl can be unlocked in an integrally linked manner by controlling the pedal. Such a structure is very easy to operate by simply controlling the pedal, and said structure is simple to implement, effectively reducing the cost and facilitating mass production for use.
