The shapes and sizes of slot 7-23 are matched with the lower part of transmission shaft 7-11, prevent eccentric wheel 7-2 and transmission shaft 7-11 from generating opposite
Rotation.
Further, clutch positioning device 7-1 further includes knob 7-12, positioning column 7-13, reset spring 7-14 and determines
Position elastic slice 7-15；The bottom of knob 7-12 is arranged in positioning column 7-13, and reset spring 7-14 is located in positioning column 7-13 and both ends
It is threaded through the outer wall of positioning column 7-13, the top of transmission shaft 7-11 is threaded through in reset spring 7-14, the bottom of reset spring 7-14
One end is arranged between two semicolumns on the top transmission shaft 7-11 and is connected to positioning column 7-13, as shown in figure 9, reset herein
The bottom end of spring 7-14 passes through groove 7-111, and Location resilient piece 7-15 is arranged in the bottom positioning column 7-13, and Location resilient piece 7-15 is resisted against
On installation base plate 2, knob 7-12 can be used for rotating clutch positioning device 7-1 manually.
As shown in figs, positioning column 7-13 is hollow cylinder, and the bottom of positioning column 7-13 is opening-like, positioning column
The top of 7-13 has the card slot of flat, and the bottom of knob 7-12 has the pillar of flat, and pillar is fastened in card slot, realizes rotation
Button 7-12 is connected with positioning column 7-13, will not produce relative rotation, and knob 7-12 is able to drive positioning column 7-13 rotation；Positioning
The card column being inserted in the groove 7-111 of transmission shaft 7-11 is equipped with inside column 7-13, card column is cylindrical body, card column and groove 7-111
Clearance fit, card column can prevent reset spring 7-14 from moving up；The outer wall of positioning column 7-13 have transmission positioning convex column 7-131 and
Locating slot 7-132；It is driven positioning convex column 7-131 at least two, is the cylindrical body being wholely set with positioning column 7-13, transmission positioning
The downwardly projecting bottom in positioning column 7-13 in the bottom of pillar 7-131；The L-shaped setting of locating slot 7-132 is convenient for reset spring
7-14 is installed into positioning column 7-13, there are two locating slot 7-132 is symmetrically set, is driven positioning convex column 7-131 and locating slot 7-
132 are staggered, and the both ends of reset spring 7-14 are arranged in two locating slot 7-132, reset spring 7-14 and positioning column respectively
7-13 has mutual active force.
As shown in Figure 8 and Figure 11, Location resilient piece 7-15, including plug division 7-151 and butting section 7-152, plug division 7-151
Two are at least respectively provided with butting section 7-152, is successively staggeredly connected to form the solid that plug division 7-151 is higher than butting section 7-152
Annulus, each plug division 7-151 are equipped with a transmission location hole 7-1511, and it is fixed that transmission positioning convex column 7-131 is arranged in transmission
Position hole 7-1511, rotates Location resilient piece 7-15 with positioning column 7-13；Each butting section 7-152 is equipped with a sinking
Positioning convex platform 7-1521, butting section 7-152 is resisted against on installation base plate 2, and positioning convex platform 7-1521 can be with installation base plate 2
Location hole 2-23 fastens, and plays support positioning action.
Further, the top positioning column 7-13 is cased with pressing plate 7-16, as shown in figure 8, pressing plate 7-16 and positioning column 7-13
Upper surface contact, pressing plate 7-16 are fixed on 2 top of installation base plate with fastener, play to positioning column 7-13 and its contained spring 7-
14 Z-direction position-limiting action.
It illustrates, during the motor-operating mechanism of disengaging type is engaged, knob 7-12 is rotated clockwise, and is made
The positioning column 7-13 for obtaining its bottom drives reset spring 7-14, transmission shaft 7-11 and eccentric wheel 7-2 to rotate simultaneously, eccentric wheel 7-2
Decelerating motor fixed plate 5 is driven to rotate, decelerating motor fixed plate 5 rotates the gear reduction box 6 fastened with it toward the left side, realizes
Gear reduction box 6 is engaged with the rack gear 3-22 of sliding tooth plate 3, and handle 10 switches to auto state.In the process, The gear deceleration
The tooth top of 4th gear set 6-6 of case 6 then engages success to the roller seating space of the rack gear 3-22 of sliding tooth plate 3.But in The gear deceleration
In 4th gear set 6-6 of case 6 and the rack gear 3-22 engagement process of sliding tooth plate 3, due to not knowing for the two position, has and nibble
Unsuccessful situation is closed, that is, decelerating motor fixed plate 5 does not go to the position engaged that can succeed to the left, control is slowed down electric
The eccentric wheel 7-2 that machine fixed plate 5 rotates also is not rotated to the position engaged that can succeed, and positioning column 7-13 is in success
The position of engagement, at this point, the angle for the transmission shaft 7-11 rotation connecting with eccentric wheel 7-2 and the angle of positioning column 7-13 rotation are simultaneously
It is inconsistent, so the reset spring 7-14 being connected with transmission shaft 7-11 and positioning column 7-13 will have because of above-mentioned differential seat angle
There is the storage of torsion, after motor rotation, so that the case where the 4th gear set 6-6 is rotated, and the tooth top that is staggered is to tooth top, eccentric wheel 7-
2 and transmission shaft 7-11 is under the action of the torsional return of reset spring 7-14, so that decelerating motor fixed plate 5 continues band movable tooth
Wheel reduction gearbox 6 turns left, and completes the 4th gear set 6-6 and engages with slip teeth article 3-22, at this time the positioning convex platform 7- of Location resilient piece
1521 match with the location hole 2-23 of installation base plate 2.The above process is the runback bit function of conversion equipment 7.
Certainly, in roller seating space of the roller seating space of the 4th gear set 6-6 of gear reduction box 6 to the rack gear 3-22 of sliding tooth plate 3,
In general, not decelerating motor fixed plate 5 does not go to the position engaged that can succeed to the left, only motor is needed to rotate, and drives
4th gear set 6-6 rotation, can realize and successfully engage.
During the motor-operating mechanism of disengaging type is separated, knob 7-12 is rotated counterclockwise, positioning column 7-13
Reset spring 7-14, transmission shaft 7-11 and eccentric wheel 7-2 is driven to rotate simultaneously, eccentric wheel 7-2 drives decelerating motor fixed plate 5 past
It turns right dynamic, decelerating motor fixed plate 5 rotates the gear reduction box 6 fastened with it toward the right, realizes gear reduction box 6 and sliding
The rack gear 3-22 of tooth plate 3 is separated, so that handle 10 is cut into manual mode.

The rotation of structure 7 drives decelerating motor fixed plate 5 to deflect, and then entire gear reduction box 6 is driven to move along the x axis, so that the
Four gear set 6-6 can with sliding tooth plate 3 rack gear 3-22 separate or engage, thus complete motor-operating mechanism manual mode and
The conversion of auto state；It is equipped with reset spring 7-14 in switching mechanism 7, succeeds from hand from state in motor-operating mechanism and cuts
Auto state is changed to, by the rotation differential seat angle between transmission shaft 7-11 and positioning column 7-13, reset spring 7-14 stores torsion,
After motor drives the 4th gear set 6-6 rotation, the restoring force of reset spring 7-14 subtracts decelerating motor fixed plate 6 and gear
Fast case 6 is toward moving left, and realization gear reduction box 6 is successfully engaged with the rack gear 3-22's of sliding tooth plate 3, thus successful conversion handle
10 use state；Instruction mandril 11 moves upwards, and pushes instruction sliding block 14 to touch microswitch 16, to indicate sliding block 14
" dividing ", printed words can appear in display window 1-31, and microswitch 16 generates and transmits the gate-dividing state of breaker；Instruction top
Bar 11 moves downward, and pushes instruction sliding block 14 to separate with microswitch 16, to indicate that " conjunction " printed words of sliding block 14 can occur
In display window 1-31, microswitch 16 generates and transmits the "on" position of breaker.
