Other structural parts in this circuit breaker all are the same with the common circuit breaker structural part on the market at present, and only operating device is different, and present operating device is spring mechanism, and it is very easily to appear the condition that the part is not hard up or wearing and tearing in long-term use for the handle is easily appeared closing the back and is divided promptly or close not fully when closing and lead to the contact to connect untight condition and take place.

The mechanism has a safety function, when the mechanism is normally folded, the position determination operation can be realized through the two main and auxiliary stage positioners on the mechanism, namely, the mechanism rotates to a position and stops at the position, once the current flowing through the electromagnetic release 8 is large, the handle can be reset immediately, the contact force of the contact conducting strip 801 and the conductive contact 203 can be improved, and the phenomenon that the handle is separated after being folded can be avoided. It can be understood that the reason that the phenomenon is generated after the closing is that internal parts are loosened or generate large abrasion, and if the current overload reason needs electrician overhaul personnel, the breaker with the safety function can also perform power supply trial operation of the contact when the breaker is closed, namely, the handle is shifted to enable the contact to be just attached, at the moment, the handle can be reset immediately if the current overload happens, and the handle can be shifted to the maximum position if the current overload does not happen.

As shown in fig. 1 and 5, the handle auxiliary closing mechanism 2 includes a fixed shaft 201 connected to the housing 9 and an auxiliary closing plate 202 sleeved on a side wall of the fixed shaft 201 and connected to a side wall of the push handle 1, a conductive contact 203 is installed on a side wall of the auxiliary closing plate 202, a deflecting column 204 connected to the push handle 1 is installed on the auxiliary closing plate 202, a trigger 6 connected to the housing 9 is installed on one side of the electromagnetic trip 8 close to the push handle 1, an auxiliary positioner 5 connected to the housing 9 is installed on one side of the trigger 6 away from the electromagnetic trip 8, a position retainer 4 connected to the housing 9 and used for pushing the auxiliary positioner 5 to position is installed on one side of the auxiliary positioner 5 away from the trigger 6, and a main positioner 3 connected to the position retainer 4 and used for assisting the rotation of the closing plate 202 and positioning the auxiliary closing plate 202 is installed on the auxiliary closing plate 202.

The pushing handle 1 drives the auxiliary closing disc 202 and the main positioner 3 to rotate towards one side far away from the pushing handle 1 by taking the fixed shaft 201 as the center through the deflection column 204, the rotary auxiliary closing disc 202 drives the conductive contact 203 to contact with the contact conductive sheet 801, the main positioner 3 is driven to deflect and push the clamping device 4 and be clamped by the clamping device 4 through the rotary auxiliary closing disc 202, and the movable clamping device 4 pushes the auxiliary positioner 5 to be clamped again.

When the handle auxiliary mechanism 2 is operated, the position of the handle can be freely regulated and controlled through the positioning safety function of the handle, so that the situation that the produced closed parts are separated when the internal parts of the equipment are loosened or abraded greatly is avoided.

When the device is implemented, the pushed handle 1 can drive the auxiliary closing disc 202 and the primary positioner 3 to rotate towards one side far away from the pushed handle 1 by taking the fixed shaft 201 as the center through the deflection column 204, at the moment, the rotary auxiliary closing disc 202 can drive the conductive contact 203 to contact with the contact conductive sheet 801 so as to conduct conductive operation, meanwhile, the rotary auxiliary closing disc 202 can drive the primary positioner 3 to deflect together and push the clamping device 4 and be clamped by the clamping device 4, at the moment, the primary positioner 3 and the clamping device 4 can play a role in primary positioning, the movable clamping device 4 can push the secondary positioner 5, so that the position of the clamping device 4 is further fixed, namely, the position of the clamping device 4 cannot move easily, even if the clamping device 4 is loosened, the clamping device 4 can firmly fix the primary positioner 3 under the action of the auxiliary positioner 5.

As shown in fig. 1, fig. 2 and fig. 5, the primary positioner 3 includes a driving post 301 connected to the auxiliary closing plate 202, a clamping post plate 302 is installed at one end of the driving post 301 away from the auxiliary closing plate 202, an inclined sliding slot 303 is formed at one side of the clamping post plate 302 away from the driving post 301, a plurality of clamping grooves 304 are formed on the surface of the inclined sliding slot 303, a blocking piece 305 is installed on the clamping post plate 302, and a blocking groove 306 is formed on the blocking piece 305.

The stop piece 305 is mainly used for blocking the position of the catch block 404, and preventing the catch block 404 from moving to the end of the catch disc 302 close to the handle, so as to avoid the situation that the catch disc 302 cannot be stuck again.

In this embodiment, fig. 1 shows the state of the dial portion of the push handle 1, and fig. 5 shows the state of the push handle 1 without being dialed.

The primary positioner 3 can prevent the primary positioner 3 from being separated from the clamping device 4 caused by part abrasion; during the specific implementation, the movable auxiliary closing plate 202 drives the column 301 and the column clamping plate 302 to move together, at this time, the clamping block 404 slides along the inclined plane of the inclined chute 303 on the movable column clamping plate 302, because the inclined chute 303 is provided with the clamping groove 304, the clamping block 404 is embedded into the clamping groove 304 during the sliding process, when the column clamping plate 302 deflects to the point that the column clamping plate cannot move continuously, the clamping block 404 is positioned at the end of the inclined chute 303, and meanwhile, the pushing column 403 is also positioned at the maximum deflection.

This clamping groove 304 cross section is selectable cylindricly, and its groove width numerical value equals clamping block 404 thickness, so when clamping block 404 slides to contact clamping groove 304, can directly imbed in clamping groove 304, so just played the effect of lock, and clamping block 404 is when long-term the use, the border position of clamping groove 304 can take place wearing and tearing, nevertheless because of clamping block 404 is directly imbed in clamping groove 304, when vibrations produce or tentatively fold, clamping block 404 also can be firmly blocked in clamping groove 304.

Since the width of the insertion groove 304 is equal to the width of the locking block 404, when the locking block 404 is inserted into the insertion groove 304, the stability between the entire stud plate 302 and the locking block 404 is high.
