When the pulley assembly is not required, the pulley assembly can be disassembled, as shown in the front view of the disassembled slidable folding bag as shown in Fig. 9C, the separate pulley assembly, the support frame and the slidable folding bag body can be separately placed so as to be carried The slidable folding bag is very convenient. In addition, it is convenient to install the slidable folding bag during use, such as sliding the pulley assembly into the guiding groove of the pulley assembly mounting portion of the second substrate, and selectively inserting the supporting frame into the receiving groove, thereby One can drag the slidable folding bag body, which better solves the disadvantages of the prior art. Also, the slidable folding bag can hold more items.

In order to make the slidable folding bag shown in FIG. 9A to FIG. 9D very beautiful, it is also generally possible to provide other auxiliary facilities on the outer surface of the folding bag 20, such as fonts configured with various patterns or other contents, to improve the utility of the slidable folding bag. Sex. The slidable folding bag in this embodiment is elegant and has the advantages of convenience and labor saving. The slidable folding bag in any of the above embodiments is suitable for use in various exhibitions, trade fairs, convenience stores, and supermarkets.

It should be noted that the above embodiments are only for explaining the technical solutions of the present invention, and are not intended to be limiting; although the present invention has been described in detail 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 are modified, or some of the technical features are equivalently replaced. The modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
