The rigid contact of object and handrail 4 becomes flexible contact, so as to protect to cargo.
Specific implementation process: when the height of handrail 4 needs to adjust, drive rack 52 is pulled, makes to nibble with drive rack 52
The driving gear 34 of conjunction rotates, and driving gear 34 in the course of rotation, turns bull stick 33, so that in 33 guide sleeve 331 of bull stick
It moves up and down, to realize the height adjustment of handrail 4.
When needing to carry the cargo of weight, the height of handrail 4 is turned down by drive rack 52 first, then removes cargo
It transports on handrail 4, starts driving motor 43, so that screw rod 431 is rotated with the rotor of driving motor 43, screw rod 431 is being rotated
Process push plate 432 can be moved along the axis direction of screw rod 431, to facilitate cargo transport at upper floor plate 1 or fortune
It is defeated to arrive at lower floor plate 2, it is more convenient and high-efficient.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
