When in use, the transverse tube 4 is passed through the shaft sleeve 91 to achieve the connection between the cloth table top and the support structure. The shaft sleeve 91 is provided with a plurality of openings. The shaft sleeve is provided with an opening to facilitate the extension of the folding assembly on the transverse tube and the arms connected at both ends, thereby improving the folding efficiency. The side of the cloth table top 9 is provided with a hanging bag and / or a hook. It also includes a net bag 10, which is fixed to the upper end of the arm 2 by a rivet 53.

[0080] In this embodiment, shaft sleeves 91 are provided on opposite sides of the cloth table top. When the telescopic arm 2 is extended, the cloth table top is stretched straight to form a structure tightly abutting against the telescopic arm 2, thereby increasing the flatness and supporting strength of the table top.

[0081] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the basic features of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
