The provision of the storage holes may also limit the rotation angle of the snap ring 131 and the tray 132 to 0 to 90 ° through the storage holes. The retainer ring 131 is disposed at an upper portion of the storage hole, and an upper top surface of the storage hole serves as a barrier to the retainer ring 131 to prevent the retainer ring 131 from continuing to rotate upward after being leveled. The tray 132 is disposed at a lower portion of the storage hole, and a lower bottom of the storage hole acts as a barrier against the tray 132 to prevent the tray 132 from continuing to rotate downward after being leveled.

When there is no storage hole, a baffle may be placed on the upper side of the snap ring 131 and the lower side of the tray 132 to prevent the snap ring 131 from being excessively rotated upward and the tray 132 from being excessively rotated downward.

When the holes or baffles are stored, the tray 132 is prevented from over-rotating against the drinking vessel by the storage holes and baffles.

Further, the depth of the storage hole is smaller than the thickness of the mounting panel 12, so as to prevent the storage hole from penetrating through the mounting panel 12 and exposing the snap ring 131 and the tray 132.

Based on the embodiment, the invention discloses a portable field operation workbench which comprises a box body and a box cover, wherein the box cover is covered on two side surfaces of the box body, the inner wall of the box cover is provided with a containing groove, a folding foot rest is arranged in the containing groove, and the box cover and the box body are provided with locking devices; when the box cover is unfolded from the side face of the box body, the locking device locks the box cover and the box body, and the folding foot stand is unfolded to support the box cover and enable the top faces of the box cover and the box body to be on the same horizontal plane. This portable workstation integrated design of field operations, it is small, the transportation transport of being convenient for can expand into work platform fast simultaneously, stable in structure is reliable, and structure utilization is high, and same structure possess the multiple use, has realized that a thing is multi-purpose. The drinking vessel storage device arranges the snap ring and the tray on the side wall of the installation panel 12 of the workbench to avoid hindering the operation work. The clamping ring and the tray which can be unfolded and folded are arranged, when a drinking vessel needs to be placed, the clamping ring and the tray are unfolded, the drinking vessel is placed in the clamping ring, and the tray supports the drinking vessel, so that daily use requirements are met. When not in use, the clamping ring and the tray are folded, thereby further avoiding obstructing the operation work of operators. The drinking tool capable of being unfolded and folded is matched with the workbench capable of being unfolded and folded, so that the daily use requirement of the workbench is met, the space on the workbench surface is not occupied, and the utilization rate of the workbench surface is improved.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, are included in the scope of the present invention.
