When belt wheel rotates, the band tooth on belt wheel moves along the arcwall face of tapered end, and when moving to any one end at two ends of arcwall face, the lock claw of tapered end engages with the gear teeth on tumbler outline locks thus drives whole tumbler to rotate.
The quantity of above-mentioned lock claw is 2, arranges along tumbler gear teeth arragement direction.
The toothed quantity of above-mentioned belt wheel is 3 and along belt wheel circle distribution, the quantity of described tapered end is 3.
Above-mentioned mount pad comprises bearing, damped ring and mount pad end cap, described lock sleeve stiff end is arranged in the mounting hole of bearing seat by bearing, described mount pad end cap is arranged on the outside of lock sleeve stiff end and is fixedly connected with mount pad, and described damped ring steps up between mount pad end cap and lock sleeve stiff end.
Described positive and negative rotation mechanism also comprises lock sleeve end cap, and described lock sleeve end cap is arranged on the outside of the tumbler installation end of lock sleeve, and is fixedly connected with lock sleeve by fixture.
Compared with prior art, beneficial effect is the utility model:
Positive and negative rotation mechanism provided by the utility model suitable/be rotated counterclockwise time can lock handwheel, and plug is easy to loading and unloading, and structure is simple.

Embodiment
Below by specific embodiment, and by reference to the accompanying drawings preferred version of the present utility model is described in further detail.
As in Figure 2-4, the utility model positive and negative rotation mechanism is primarily of compositions such as mount pad 1, lock sleeve 2, tapered end 4, belt wheel 3, straight pin 5, bearing 10, damped ring 9, mount pad end cap 8 and lock sleeve end caps 6.Tapered end 4 is designed to seesaw shape, is assemblied on lock sleeve 2 by straight pin 5, and it can rotate around straight pin 5; Belt wheel 3 bore design has the gear teeth 31, and belt wheel 31 is enclosed within lock sleeve 2, the gear teeth 31 on it and tapered end 4 position correspondence; The shape of lock sleeve 2 designs according to the demand of other part, and Main Function is as the mounting platform of other part and spacing; Lock sleeve 2 is installed on mount pad by bearing 10.
When positive and negative rotation mechanism is in original state, at this moment can loads or unload plug; After loading plug, when belt wheel turns clockwise, after the gear teeth on belt wheel rotate to an angle, just contact together with tapered end, then tapered end rotates also together with the contact of plug handwheel around straight pin, just can pin plug handwheel, thus drive it to turn clockwise together when rotating to certain position; When belt wheel is rotated counterclockwise, principle is identical.
Embodiment: see accompanying drawing 5, the utility model is arranged on test platform, after electric connector 13 loads, motor 14 drives the belt wheel 3 in positive and negative rotation mechanism 11 by Timing Belt 12, see accompanying drawing 1 and accompanying drawing 2 and Fig. 3, due to the effect of damped ring 9, belt wheel is made to have a rotation relative to lock sleeve 2, the gear teeth after certain angle on belt wheel will contact tapered end 4, thus drive tapered end to rotate around straight pin 5, after entering certain angle again, tapered end contacts with electric connector handwheel 7, after continuing to rotate to an angle, the gear teeth of belt wheel will block electric connector handwheel by tapered end, at this moment due to limited resistance that damped ring can provide, belt wheel-tapered end-electric connector handwheel will form one, rotate under the support of bearing 10 together.And when motor rotates, due to the seesaw structure of tapered end, make the gear teeth of belt wheel block electric connector handwheel by the other end of tapered end in the other direction.Like this, no matter clockwise or can handwheel be locked when being rotated counterclockwise.
When this device is in the left figure position of Fig. 6, belt wheel only need be made to rotate a less angle in the opposite direction, and this device just can be made to reset, and be in position shown in the right figure of Fig. 6, under this position, the handling of plug are all very convenient.
Above-described embodiment is a kind of preferred version of the present utility model, not any pro forma restriction is done to the utility model, under the prerequisite not exceeding the technical scheme described in claim, also have other variant and remodeling can also be applicable to rotation and the locking of other tumbler.
