It can move up and down in strip groove and along strip groove.
By using above-mentioned technical proposal, strip groove plays position-limiting action to straight pin, makes straight pin always along bar shaped
Slot moves up and down, and the offset of shift position will not occur, and improves accuracy of action.
Preferably, retaining ring is equipped at the top of the fixed frame, the fixed frame bottom is equipped with pedestal.
By using above-mentioned technical proposal, retaining ring and pedestal are encapsulated in active rotating shaft and passive rotating shaft on fixed frame, mention
High integrally-built stability.
In conclusion advantages of the present invention:
1. adding single-phase self-locking device in motor bottom, when using manual mode, single-phase self-locking device rotation is not
Output shaft part, but drive motor rotor brake module rotates, power supply is connected, it is not easy to motor is damaged, to play protection
The effect of motor；When active rotating shaft has rotation, straight pin is moved to highest point, sliding sleeve along the helicoid on active rotating shaft
Tooth and fixed frame card slot are in separated position, and the strip groove in passive rotating shaft leads passive rotating shaft and then under straight pin drive
The rotation of turn axis；When active rotating shaft is without rotation, for sliding sleeve under pressure spring active force, straight pin is returned to the spiral of active rotating shaft
Face lowest point, sliding sleeve tooth and the cooperation of fixed frame card slot are clamped, and passive rotating shaft latching is not able to rotate；
2. opening up strip groove in passive rotating shaft, strip groove plays position-limiting action to straight pin, make straight pin always along
Strip groove moves up and down, and the offset of shift position will not occur, and improves accuracy of action；
3. setting retaining ring and pedestal are encapsulated in active rotating shaft and passive rotating shaft on fixed frame, integrally-built stabilization is improved
Property；
It is mounted on fixed frame 4. active rotating shaft and passive rotating shaft pass through bearing, bearing is to active rotating shaft and passive rotating shaft
It plays a supportive role, reduces the coefficient of friction in active rotating shaft and passive rotating shaft motion process, and guarantee active rotating shaft and by turn
Axis rotating accuracy.
