[0041] Embodiment 1:

[0042] The utility model provides a portable observation and recording device, comprising: a writing and recording board 1, a hexagonal longitudinal support rod 101, an L-shaped insertion plate 102, a rectangular installation box 2, a U-shaped connection frame 201, a transverse support shaft rod 202, a U-shaped swing frame 203, a guide block 204, a top shaft 205, a pressure strip 3, a magnifying glass 4, a handle tube 401, and a push shaft 402. At the front end of the writing and recording board 1, two rectangular installation boxes 2 are symmetrically and fixedly arranged. The two rectangular installation boxes 2 are used for inserting the magnifying glass 4.

[0043] Among them, the outer side of the rectangular installation box 2 is open at the first end, and a top shaft 205 is fixedly arranged at the center position of the end plug plate of the rectangular installation box 2.

[0044] On the left and right sides of the front end of the writing and recording board 1, two hexagonal longitudinal support rods 101 are symmetrically and fixedly arranged. On the two hexagonal longitudinal support rods 101, two L-shaped insertion plates 102 are symmetrically slidably installed by spring pushing. The front half of the L-shaped insertion plate 102 is inserted and matched with the first end of the rectangular installation box 2 to block the magnifying glass 4 in the rectangular installation box 2, avoiding the magnifying glass 4 being directly exposed and accumulating dust during long-term storage when idle, and saving the trouble of wiping and cleaning every time it is used.

[0045] A handle tube 401 is fixedly formed on the outer retaining ring of the magnifying glass 4. A push shaft 402 is slidably installed in the handle tube 401 by spring pushing. A force receiving disc is fixed at the rear end of the push shaft 402. A retaining ring is fixedly arranged at the open end of the tail of the handle tube 401, and the force receiving disc abuts against the retaining ring. When the magnifying glass 4 is inserted into the rectangular installation box 2, the handle tube 401 is sleeved and matched with the top shaft 205, and the top shaft 205 abuts against the force receiving disc and pushes the push shaft 402 to compress the spring thereon and slide towards one end of the magnifying glass 4. When in use, the paper for recording data related to tea pests and diseases is laid on the writing and recording board 1. The magnifying glass 4 is used to magnify and observe the local details of tea tree branches and leaves to understand the damage caused by pests to tea leaves and obtain relevant pest and disease data.

[0046] When the L-shaped insertion plate 102 is slid backward and pulled out to open, the magnifying glass 4 loses the insertion and retention of the L-shaped insertion plate 102 and can be automatically ejected from the rectangular installation box 2 by the spring rebound of the push shaft 402. Compared with the prior art, it can save the trouble of directly picking with fingers or using external tools for assistance, and is convenient to operate and use.

[0047] Preferably,

[0048] A V-shaped guide block 204 is fixed inside the rectangular installation box 2 near the top shaft 205. The V-shaped side of the guide block 204 is a concave arc structure, and a through hole arranged concentrically with the top shaft 205 is opened at the center of the guide block 204. The guide block 204 can guide the handlebar 401 in the center through the inclined guiding principle of its V-shaped side, so as to facilitate the alignment of the handlebar 401 with the through hole and the top shaft 205 for plug-in assembly.

[0049] Preferably,

[0050] When the magnifying glass 4 is inserted into the rectangular mounting box 2, the tube 401 is slidably matched with the through hole.

[0051] Based on the first embodiment, the second embodiment:

[0052] A cross bracing shaft 202 is welded between the rear end blocking plates of the two rectangular installation boxes 2 .

[0053] Preferably,

[0054] A U-shaped swing frame 203 is welded between the tail end portions of the top plates of the two rectangular installation boxes 2 .

[0055] Preferably,

[0056] A U-shaped swing frame 203 is rotatably mounted on the cross bracing shaft 202 , and two tension springs are symmetrically hung between the rear end cross bracing rod of the U-shaped swing frame 203 and the top cross bracing plate of the U-shaped swing frame 203 .

[0057] Preferably,

[0058] The open end of the U-shaped swing frame 203 is hinged with a paper pressing strip 3, which is used to press and fix the front end of the paper to position the paper as a whole on the writing recording board 1. The U-shaped swing frame 203 can swing up and down to drive the paper pressing strip 3 to move up and down to tighten the paper.

[0059] Working principle: When in use, the paper for recording the data of tea pests and diseases is spread on the writing and recording board 1, the magnifying glass 4 is used to magnify and observe the local details of the tea branches and leaves, so as to understand the damage caused by pests and diseases to the tea leaves and obtain relevant pest and disease data, the paper pressing strip 3 is used to press and fix the front end of the paper, so as to position the paper as a whole on the writing and recording board 1, and the up and down swinging frame 203 can drive the paper pressing strip 3 to move up and down to tighten the paper;

[0060] The front half of the L-shaped plug plate 102 is inserted and matched with the front end of the rectangular installation box 2 to seal the magnifying glass 4 in the rectangular installation box 2 to prevent the magnifying glass 4 from being directly exposed to dust for a long time when it is idle.

[0061] When the magnifying glass 4 is inserted into the rectangular mounting box 2, the tube 401 and the top shaft 205 are sleeved and fitted. The top shaft 205 abuts against the force-receiving disc, and pushes and drives the push shaft 402 to compress the spring thereon and slide towards one end of the magnifying glass 4. When the L-shaped insertion plate 102 is slid backward and pulled out to open, the magnifying glass 4 loses the insertion and retention of the L-shaped insertion plate 102, and can be automatically ejected from the rectangular mounting box 2 by the spring rebound on the push shaft 402. The guiding block 204 can implement centering guidance on the tube 401 through the inclined plane guiding principle of its V-shaped side surface, facilitating the alignment and insertion assembly of the tube 401 with the through hole and the top shaft 205.
