The utility model is further set to: described elastic key is positioned at one end of corresponding the first end cap of connecting head, and described keyway is positioned at the other end of corresponding the first end cap of coupling band.
By adopting technique scheme, between coupling band and connecting head, there is larger slipping space, utilize to greatest extent to the greatest extent the length of coupling band, thereby reach the object that reduces coupling band length, cost-saving.
The utility model is further set to: on described key push pole, be provided with baffle plate, the opening end of described through hole is provided with for postive stop baffle and prevents the cover plate that key push pole comes off.
By adopting technique scheme, the cover plate arranging by via openings end, can prevent that key push pole from coming off from through hole by postive stop baffle, avoids the loss that comes off of component, avoids causing unnecessary loss.
The utility model is further set to: described key push pole is arranged with the second elastic component.
By adopting technique scheme, when operation, by extruding key push pole, make the second elastic component sheathed on key push pole generation deformation that is squeezed, gather elastic potential energy, when the power on acting on key push pole disappears, the second elastic component can transform the elastic potential energy of gathering, key push pole is resetted, facilitated next use.
Compared with prior art, the utility model has the advantage of: in coupling band, slippage is connected with connecting head, by squeezing by key push pole, can make the elastic key keyway of freely coming in and going out, elastic key is during with the clamping of keyway phase, whole coupling is a stable drive mechanism, during installing axle, only need select installing according to the size of the diameter of axle, and by key push pole, make elastic key shift out keyway by squeezing, toward the first end cap direction of coupling band, press simultaneously, the first elastic component is shunk, until axle moves to adaptive with it joint, reach the object of the axle that connects different model, from structure, analyze, this structure movement is more flexible, telescopic movable up and down, unloading the first end cap can also take out sheathed connecting head, be convenient to the replacing to connecting head, clean, maintenance, can also effective conserve space during placement.
