A connecting plate 27 is connected to the side of the slider seat 26 and a positioning plate 28 is connected through the connecting plate 27;

[0028] The cargo handling platform 3 is installed on the side of the positioning plate 28 and is connected thereto; The cargo guiding component 6 includes four positioning beams 61 arranged in parallel on the upper end surface of the cargo handling platform 3 in sequence; Among them, two adjacent positioning beams 61 are set as a group, and a number of deep groove ball bearings 62 are assembled on the opposite sides of the two groups of positioning beams 61; A guiding roller 63 is rotatably arranged between two adjacent deep groove ball bearings 62 facing each other.

[0029] In this embodiment, during actual use, when an operator guides goods onto the goods handling platform 3, the goods guiding wheels 64 and guiding rollers 63 on the goods handling platform 3 can guide the goods, thus driving the goods to enter onto the several goods guiding wheels 64 more quickly. At this time, through the mutual cooperation of the goods guiding assembly 6 and the goods handling platform 3, stable loading of the goods can be achieved. And through the lifting and handling assembly 2 to control the lifting movement of the goods handling platform 3, automatic handling of the goods can ultimately be realized. Compared with the automatic guided vehicle in the cited document, the AGV automatic guided vehicle body 1 of the present application can automatically handle between shelves or workbenches at different heights, so as to directly handle the loading and unloading of goods at high places, solving the height limitation problem of traditional AGVs, reducing the need for manual handling at the same time, thus reducing labor costs and also reducing the safety risks brought by manual operation.

[0030] Specifically, referring to Figure 3 , the lifting and handling assembly 2 further includes a ball bearing seat 23 arranged in the adjusting seat 22. A bearing member is assembled in the ball bearing seat 23 and is rotationally matched with the bottom end of the threaded lead screw 24.
