? The new hand-operated propulsion mechanism is applied to unit drawers, break-up operation and electric operation. It is a multi-circle laborsaving propulsion mode, which realizes easy, flexible and stable propulsion and removal of drawers. Three-station tool It has mechanical positioning and display, and has a "click" position sound prompt function, which makes it easy and flexible to promote the three-pole and four-pole drawers of 630A; Closing interlock has the function of re-locking and resetting, and the principle of propulsion mechanism and the technology of interlocking mechanism are advanced. Among them, the special interlocking mechanism for electric operation can ensure that the drawer can be moved only
by cutting off the switch, effectively preventing misoperation, and realizing that the electric operation mechanism can not take electricity when the rocking handle enters the mechanism (operational state), and only when the rocking handle is pulled out, the electric operation mechanism can take electricity, which makes the empty opening and electric closing have high operation safety;
? The new hand-pulled propulsion interlocking mechanism is applied to the unit drawer, which has the functions of three-position locking, display, closing interlocking position auxiliary power supply, and switch re-button reset function;
? The new small hand-pulled propulsion mechanism is applied to 1/2 and 1/4 drawer units, and has the functions of three-position locking, display, closing interlock position auxiliary power supply, and switch re-buckling reset function;
? The new push interlocking mechanism of drawer has mechanical display of separation, test and connection position, and the electrical contacts are synchronized with the position
