so that the contact block 95 at the lower end of the rear side face of the moving block 94 is inserted into the second-stage threading hole 71, the contact block 95 is in contact with the second-stage conducting wire 7, current is transmitted to the moving block 94 through the second-stage conducting wire 7 by the storage battery 23, is transmitted to the metal wire 93 through the moving block 94 and then is transmitted to the touch screen 3 through the first-stage conducting wire 6, the power is supplied to the touch screen 3 through the storage battery 23, then the mobile phone is wirelessly connected with the touch screen 3 through Bluetooth, the order grabbing can be carried out through the touch screen 3, the voice navigation function is started after the order grabbing is finished, a distributor does not need to hold the mobile phone with one hand and one riding hand, the safety is improved, the optimal route is selected through navigation, the goods delivery efficiency is improved, because the frame 31 of the touch screen 3 is movably connected with bearings in the first-stage shaft grooves 32 on the left and right sides of the placing groove 11 through the first-stage rotating shaft 33, the angle of the touch screen 3 can be adjusted by pressing the front side of the upper end face of the touch screen 3, so that the influence of reflection on the order information of a distributor is avoided, the influence of reflection on the distribution and the observation of the road traffic condition in front is also avoided, the use safety is improved, when the touch screen 3 is rotated downwards, the left pin shaft 43 is bounced into the primary limiting hole 35 at the lower end of the right side face of the primary limiting plate 34 of the touch screen 3 under the action of the spring 42, so that the touch screen 3 is limited, the touch screen 3 is prevented from rebounding to the original position due to bumping in the riding process, the touch screen 3 is prevented from shaking when the touch screen 3 is touched by hand, the distribution operator can conveniently perform order grabbing operation through the touch screen 3, the distribution operator rides the storage battery car to search in a street lane, the photovoltaic panel 24 continuously absorbs sunlight, and solar energy is converted into electric energy to be stored in the storage battery 23, the model of the charging controller 22 is TSM101ACDT, the charging amount of the storage battery 23 is controlled by the charging controller 22, when the storage battery 23 is fully charged, the photovoltaic panel 24 is cut off to supply power to the storage battery 23 by the charging controller 22, the storage battery 23 is prevented from being oversaturated, the service life of the storage battery 23 is shortened, the outer surfaces of the storage battery 23 and the charging controller 22 are respectively sleeved with a flexible protective pad, the storage battery 23 and the charging controller 22 can be prevented from being damaged due to collision between the storage battery 23 and the charging controller 22 and the box body 21 caused by bumping, the cover plate 25 is fixedly connected to the upper end surface of the box body 21 through screws, the storage battery 23 and the charging controller 22 are convenient to overhaul by disassembling the cover plate 25 at the later stage, the storage battery 23 provides electric energy for the touch screen 3, so that the electric energy is saved, the protective cover 5 is pulled up in sunny days, so that a distributor can rob orders through the touch screen 3, in the process of pulling up the protective cover 5, the secondary limiting plate 51 rotates around the secondary rotating shaft 52, the right pin shaft 43 is bounced into a second-stage limiting hole 54 at the lower end of the left side surface of a second-stage limiting plate 51 under the action of the spring 42, so that the protective cover 5 is limited, the protective cover 5 is prevented from covering the touch screen 3 due to bumping and falling down in the riding process to influence a distributor to rush orders through the touch screen 3 when meeting rainy days, the protective cover 5 is pulled down to avoid the influence of rainwater on the touch screen 3 when meeting rainy days, the touch screen 3 can be protected through the protective cover 5 when meeting sandy days, the sandy dust is prevented from being attached to the touch screen 3 to influence checking, after the protective cover 5 is pulled down, the right pin shaft 43 supports the second-stage limiting plate 51 under the action of the spring 42 to prevent the protective cover 5 from being warped due to bumping to rainwater on the touch screen 3 to influence use when meeting rainy days and insufficient sunlight, the electricity stored in the storage battery 23 is consumed completely, accessible rotating threaded rod 91 drives movable block 94 and moves forward, thereby make contact block 95 of movable block 94 leading flank lower extreme insert in tertiary through wires hole 81, make contact block 95 and the contact of tertiary wire 8, because tertiary wire 8 and storage battery electric connection of storage battery car, thereby make touch-sensitive screen 3 obtain the power output of storage battery and can continue to use, the availability factor of touch-sensitive screen 3 has been improved when practicing thrift the electric energy, end fixedly connected with insulating knob at threaded rod 91, avoid the rotating in-process to take place the electric shock, the security has been improved, wire 93 is helical structure, avoid the movable block 94 to break wire 93 at the in-process that moves in the front and back, 6 parts that are located standing groove 11 inside of one-level wire are the heliciform, avoid breaking 6 with one-level wire at the in-process of rotatory touch-sensitive screen 3, the life-span of the equipment of improvement.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
