[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 5 , a workpiece transport trolley, comprising a frame body 1, above which a transport table panel 2 is installed. At the top of the front end of the frame body 1, a transport table panel lifting assembly is installed, and at the bottom of the front end, a directional caster 12 is installed. At the top of the rear end of the frame body 1, a push rod 3 is installed, and at the bottom of the rear end, a swivel caster 11 is installed; the transport table panel lifting assembly includes a pair of linear bearings 10 installed at the top of the front end of the frame body 1, and also includes a pair of guide shafts 4 installed under the front end of the transport table panel 2. Washers 7 are installed on the guide shafts 4, and the guide shafts 4 are assembled through the linear bearings 10.

[0022] In the above embodiment, three pairs of cam followers 5 are symmetrically installed on the front end upper surface of the transport table panel 2. The three pairs of cam followers 5 guide the trolley to make the trolley enter a predetermined position; a pair of positioning bushings 6 are symmetrically installed on the front end upper surface of the transport table panel 2.
