[0002] As is well known, the common traditional test signs at present can only indicate on one side and cannot make good use of both sides for display. At the same time, the display content cannot be replaced timely and conveniently. Especially in scientific experiment sites, most of the existing test signs cannot be preset and adjusted in height as needed, and the marked content cannot be freely replaced.
[0003] The existing signs that can replace the marked content generally involve complex technologies such as electro-optics and sound, and are not suitable for portable use in scientific experiment farmlands. There is an urgent need for a marking device that has simple usage technology, is suitable for field tests in different topographies and landforms, can meet the timely replacement of the marked content, adjust the height of the sign, etc. Therefore, we propose a portable test sign device to solve the above problems.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all 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.
[0020] Please refer to Figures 1-3, a portable test sign device of the present utility model includes a support base 1. The support base 1 is relatively heavy in weight, making it convenient to support the support base 1 of the portable test sign device. A height-adjustable telescopic rod 2 is provided at the top of the support base 1. A U-shaped sliding adjustment seat 3 is provided at the top of the height-adjustable telescopic rod 2. A sliding adjustment roller 4 is provided in the middle of the U-shaped sliding adjustment seat 3. The sliding adjustment roller 4 cooperates with the height-adjustable telescopic rod 2. The cooperation mode between the sliding adjustment roller 4 and the U-shaped sliding adjustment seat 3 is a sliding fit, so that the sliding adjustment roller 4 can slide and adjust along the U-shaped sliding adjustment seat 3. A switch-adjustable telescopic rod 5 is provided at the top of the U-shaped sliding adjustment seat 3. A positioning rod 6 is provided at the left end of the switch-adjustable telescopic rod 5. A sign cloth piece 7 is provided between the positioning rod 6 and the sliding adjustment roller 4. The sign cloth piece 7 cooperates with the positioning rod 6 and the sliding adjustment roller 4. The cooperation mode between the sign cloth piece 7 and the positioning rod 6 and the sliding adjustment roller 4 is a detachable fit, which is a zipper-type disassembly and assembly, making it convenient to disassemble and assemble the sign cloth piece 7 with the positioning rod 6 and the sliding adjustment roller 4.
