The corners at the entrance and exit of the trolley main rail are set to be right angles. When the driving device drives the chain guide rail assembly to transport goods, when the goods are transported to the right angle corner at the entrance or exit, the transportation is prone to be unsmooth, which may cause the push block in the chain guide rail assembly used to drive the trolley main rail to fall off when driving the goods, posing a safety hazard.

DETAILED DESCRIPTION
[0016] Reference Figure 1-3 A lifting device embodiment of the utility model is further described.
[0017] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.
