The limiting slide rail 24 is slidably set inside the slide groove 112, and the limiting slide rail 24 is in conflict with the top of the flange 1121. A limiting block 18 is provided on the rear side of the slide groove 112. When the extension plate 20 is retracted, the limiting slide rail 24 is in conflict with the limiting block 18.

[0029] As a preferred embodiment, the limiting slide rail 24 is made of iron, and a magnet is provided on the front side of the limiting block 18. After the extension plate 20 is recovered, the extension plate 20 is fixed by the magnet to prevent the extension plate 20 from sliding out by itself during the transportation of the workbench. The extension plate 20 can be slid out with a little force when in use.

[0030] In this embodiment, a placement groove 21 is opened on the top front side of the extension plate 20. The extension plate 20 is provided to increase the working area of ​​the workbench, and the placement groove 21 is provided to provide a certain limit for the equipment and items placed on the increased working area to prevent the equipment from sliding off the extension plate 20.

[0031] In this embodiment, slots a111 are provided at the bottom of the first table top 11 near the four corners, and slots b22 are provided at the top of the extension plate 20 near the two rear corners. After the extension plate 20 is fully unfolded, the slot b22 is coaxial with the slot a111 on the front side of the first table top 11, and the telescopic leg 30 can be inserted into any slot a111 or slot b22. In specific use, the telescopic leg 30 embedded in the recovery groove 23 is taken out, and the extension plate 20 is fully unfolded. First, the two telescopic legs 30 are inserted into the two slots a111 on the rear side, and then the other two telescopic legs 30 are respectively inserted into the slots b22 and slots a111 on the front side. In this way, the unfolded extension plate 20 is further fixed and its longitudinal force strength is enhanced. The installation and recovery method of the telescopic leg 30 fully considers the portability and folding characteristics of the workbench. It is not only convenient to carry, but also can be quickly unfolded into a stable working platform when needed, providing great convenience for users.

[0032] Specifically, the working principle of the portable workbench for the dynamic strain signal acquisition instrument is as follows: when in use, first take out the four telescopic legs 30 from the recovery slot 23 and adjust them to an appropriate height. Then, completely slide out the extension plate 20 and insert the telescopic legs 30 into the slots a111 and b22 to ensure that the workbench is stably placed on the ground. Then, easily open the lock 16 and lift up the second table top 12 until its rear side contacts the bow-shaped baffle 17. During this process, the third table top 14 is unfolded along with the unfolding of the second table top 12 through the transmission of the connecting rod 15. At this point, the workbench is unfolded and the relevant equipment can be placed on it to start data collection. The above structure solves the problem of placing the equipment directly on the ground, causing friction between the data line interface, sensors and other equipment components and the ground, causing wear on the equipment surface, and dirt and dust on the ground invading the interface, resulting in poor contact and affecting the accuracy and stability of data collection.
