The specific embodiment

Preferred embodiment of the utility model such as Fig. 1, Figure 1A, Fig. 2, Fig. 2 A and shown in Figure 3.Because the utility model is the improvement at clutch, so do not draw control circuit that is contained in casing 10 inside and the motor that is subjected to its control, for transmission mechanism, also just emphasis has drawn, and it cranks arm 20.

As can be seen, main shaft 30 wherein is contained in two rigid bearings 301 from Fig. 1 to Fig. 3, and an end of main shaft is fixedlyed connected with restrictor bar 40.20 positions that are sleeved on the main shaft near the restrictor bar inboard of cranking arm in the transmission mechanism can be around spindle swing under the driving of motor.

From Fig. 1 to Fig. 3, as can be seen, be provided with a guide 505, latch 501 and back-moving spring 502 are housed in guide in restrictor bar 40 inboards.The lower end of back-moving spring is limited by the step on the latch, and the upper end is limited by hard-wired locating part 503, when extracting latch, and the back-moving spring pressurized, thus can produce the elastic force that latch is pushed away downwards.As can be seen from the figure, the upper end of latch 501 is exposed to the top of guide.In addition, be provided with a bayonet socket 201 on 20 cranking arm, its width is slightly larger than the diameter of latch lower end, makes the lower end of latch can insert or extract this bayonet socket 201.

During operate as normal, in the bayonet socket on the lower end of latch 501 is inserted in and cranks arm, 20 driven and when swinging when cranking arm, its bayonet socket 201 can rotate around the axle center of main shaft 30, because the lower end of latch is inserted in the bayonet socket, just by latch will crank arm and restrictor bar linked together, make crank arm, be interlock between main shaft and the restrictor bar, can drive restrictor bar when rotating so crank arm rotates together, but and then the lifting and putting down of control sluice bar, Figure 1 shows that down state, Figure 2 shows that the state of lifting.

When breaking down or have a power failure, current with restrictor bar is that down state is an example, if there is vehicle to pass through, then needs to lift restrictor bar.In the present embodiment, only need simply latch 501 be extracted from the bayonet socket of cranking arm with hand, rotate simultaneously restrictor bar 40 a little, can realize removing the function of connection, because the lower end of latch was extracted from bayonet socket and dislocation was taken place with it this moment, thus the rotation of restrictor bar can not be subjected to cranking arm limit.Removed after the connection, used the hand propelled restrictor bar, can easily it have been changed to the state of lifting by down state, so that vehicle passes through.After trouble shooting or power supply normally, by applying a control signal of lifting restrictor bar, can make cranks arm swings to position in the time of restrictor bar can being lifted fully, because this moment, restrictor bar also was to be in the state of lifting, so being contained in the latch of restrictor bar inboard can be under the effect of back-moving spring 503, automatically be inserted in the bayonet socket of cranking arm, just recovered automatically to crank arm with restrictor bar between be connected.

Restrictor bar is in the state of lifting if break down or when having a power failure, and also can remove and restrictor bar is pressed onto down state after connecting by extracting latch; After trouble shooting or power supply were normal, by applying a control signal of putting down restrictor bar, can make cranks arm swung to position in the time of restrictor bar can being put down fully, thus recover automatically to crank arm with restrictor bar between be connected.

By among Fig. 3 as can be seen, be convenient to staff plug operation, in the upper end of latch 501 a discoid cap 504 that draws is housed, when specifically implementing, also can draw cap with substituting this with structures such as drag hooks.In addition, when specifically implementing, can also be with enclosed hole clipping replace cranking arm bayonet socket 201 on 20.
