each other, coordinates in the lower end of the first connecting rope 50 and sets Clip 12 is put, connector sleeve 5 opens up the first groove 13, the width matching of the first groove 13 and the first connecting rope 50 along its length It closing, the second groove 14, fixing groove 15 and holding tank 18 is opened up respectively on connector sleeve 5, the first groove 13 is communicated with the second groove 14, Second groove 14 is matched with the width of clip 12, and the second groove 14 is communicated with fixing groove 15, fixing groove 15 and 18 phase of holding tank Logical, the fan-shaped limiting plate 16 of setting, the inside cambered surface of limiting plate 16 are matched with 12 outer surface of clip in fixing groove 15, limiting plate Limiting slot 17, the connecting pin matching ends of limiting slot 17 and clip 12, the outside of limiting plate 16 are opened up in 16 inside cambered surface Gear ring is set in cambered surface, setting first gear 19, electric shifting fork 24 and fixed plate 25 in holding tank 18, gear ring always with the first tooth 19 engagement of wheel, first gear 19 are mounted on first gear axis 23, and set key 26 in fixed plate 25, electric shifting fork 24 can be by the One gear shaft 23 is allocated to be coordinated with key 26, and far module is set on electric shifting fork 24, sets at least two to fix in fixing groove 15 Bar 21 opens up the sliding slot 22 of arc on limiting plate 16, and fixed link 21 is located in sliding slot 22, and limiting plate 16 can pass through 22 edge of sliding slot Fixed link 21 rotates in fixing groove 15, and connecting hole 6 and link slot 7 are opened up in connector sleeve 5, and connecting hole 6 and link slot 7 communicate, Setting second gear axis 9 in link slot 7, second gear axis 9 is linked with first gear axis 23 by transmission device, second gear axis Second gear 8 is set on 9, and the first rack 10 and the second rack 11 are engaged in 8 both sides of second gear respectively, and 10 lower end of the first rack leads to It crosses the first cross bar and connects several first clamp bars 27,11 upper end of the second rack connects several second clamp bars 28, number by the second cross bar A first clamp bar 27 and several second clamp bars 28 are respectively positioned in connecting hole 6, and the upper end of the second connecting rope 51 is located at the several first folders Between item 27 and several second clamp bars 28.The size of installing plate 2 is identical with the inner wall size of housing 1.This structure can remove When transporting mobile shell, two connecting ropes are connected using connector sleeve 5, then moved rotary electric machine 48 and wire spool 49 is driven to rotate, so as to Each tank body that installing plate 2 connects above is sling, housing 1 is in moving process is carried, the vibrations of generation or the power of shaking, meeting There is connecting rope absorption, so as to mitigate the power that each tank body is subject to, be damaged when each tank body being avoided to carry.First connecting rope 50 is with connecting When female connector 5 connects, close up clip 12, clip 12 is made to be fixed on the lower end of the first connecting rope 50, by 12 and first connecting rope of clip 50 are pushed into the second groove 14 and the first groove 13 respectively, and after clip 12 enters the second groove 14, connecting pin end enters limiting Limiting slot 17 on plate 16, rotation connection set 5 or first connecting rope 50, make limiting plate 16 turn to opposite side, so as to drive the One gear 19 rotates, and after the completion of rotation, by controlling electric shifting fork 24, it is made to be allocated to first gear axis 23 and is coordinated with key 26, So as to make first gear axis 23 can not circumferential movement, make limiting plate 16 that can not be rotated back to original position, due to the first connecting rope 50 It can be moved along the first groove 13, and clip 12 leads to it since the limiting slot 17 that its connecting pin end is limited on plate 16 blocks Can not be moved along the second groove 14, so as to which connector sleeve 5 be made to fix the first connecting rope 50 and clip 12 so that connector sleeve 5 with First connecting rope 50 connects.Before connector sleeve 5 is connect with the upper end of the second connecting rope 51, the upper end of the second connecting rope 51 is put into number Between a first clamp bar 27 and several second clamp bars 28, after being connect after the lower end of the first connecting rope 50 with connector sleeve 5, first gear Axis 23 can generate rotation, and second gear axis 9 is driven by first gear axis 23 to be rotated, and makes several first clamp bars 27 and several second Clamp bar 28, which moves towards, clamps the upper end of the second connecting rope 51, behind the upper end for clamping the second connecting rope 51, the electricity in connector sleeve 5 First gear axis 23 is allocated to by dynamic shift fork 24 to be coordinated with key 26, so as to make first gear axis 23 can not circumferential movement, i.e. the second tooth Wheel shaft 9 can not rotate, so as to complete the fixation of the lower end to the first connecting rope 50.During disengaging, electric shifting fork 24 is controlled, makes it will First gear axis 23 is dialled from the key 26 in fixed plate 25, and so as to which first gear axis 23 be enable to rotate, the second connecting rope 51 is certainly It is disconnected from sleeve 5 under body gravity, during disengaging, the second connecting rope 51 can strut the first clamp bar 27 and the second clamp bar 28, the first clamp bar 27 and second clamp bar 28 be located remotely from each other and rotate second gear axis 9, so as to which first gear axis 23 be driven to rotate, make limiting plate 16 multiple Position, so as to which connector sleeve 5 be made to be detached from the first connecting rope 50.The configuration achieves the first connecting ropes 50 and the second connecting rope 51 Dynamic locking, convenient for storing and connecting.This connection mode is connected and disconnected from conveniently, due to no exposed switch and prominent during connection Go out object, other objects and connector sleeve 5, which touch, can not also make to be mutually disengaged between rope, and when storage facilitates each connecting rope to be detached from, just In separated storage, convenient for collecting and arrangement.Transmission device can be gear drive, chain transmission, Worm Wheel System etc. Various structures.

Torsional spring 29 is set on the second gear axis 9.This structure can store power, solution in locking by torsional spring 29 During lock, torsional spring 29 reverses second gear axis 9, so as to make the first connecting rope 50 and the second connecting rope 51 are automatic to disengage.
