The microscopic observation mechanism 3 comprises a microscope and a camera, wherein the camera is connected with an ocular lens of the microscope, and an objective lens of the microscope is used for aligning a test piece. The clamp 1 and the upright post can be connected by interference fit.
In this embodiment, when the moving platform is directly disposed on the experimental platform or the distance between the moving platform and the experimental platform is small, the moving platform is easy to interfere with other experimental mechanisms on the experimental platform, and when the distance between the moving platform and the experimental platform is large, the limiting observation mechanism disposed on the moving platform is difficult to observe the test piece disposed on the experimental platform. Because clamp 1 cover is established on the stand, and clamp 1 highly can be adjusted on the stand, because moving platform sets up on clamp 1, when adjusting clamp 1 highly on the stand, can drive moving platform motion simultaneously to adjust the distance between moving platform and the experiment platform.
In general, because clamp 1 cover is established on the stand, and clamp 1 highly can be adjusted on the stand, because moving platform sets up on clamp 1, when adjusting clamp 1 highly on the stand, can drive moving platform motion simultaneously, adjusts the distance between moving platform and the experiment platform. Therefore, the height of the clamp 1 on the upright post is adjusted, so that a proper distance is kept between the mobile platform and the experimental platform, and the microscopic observation mechanism 3 arranged on the mobile platform can observe a test piece on the experimental platform and prevent the mobile platform and other mechanisms from interfering.

Wherein the test piece is arranged on the right side of the microscopic observation mechanism 3.
In this embodiment, the first moving mechanism 21 is vertically disposed, when the second moving mechanism 22 and the first moving mechanism 21 slide relatively, the second moving mechanism 22 moves in the vertical direction, and since the third moving mechanism 23 is disposed on the second moving mechanism 22, the microscopic observation mechanism 3 is disposed on the third moving mechanism 23, and when the second moving mechanism 22 moves in the vertical direction, the third moving mechanism 23 and the microscopic observation mechanism 3 can be driven to move in the vertical direction. Similarly, the second moving mechanism 22 is disposed along the front-rear direction, and when the third moving mechanism 23 and the second moving mechanism 22 slide relatively, the third moving mechanism 23 moves along the front-rear direction, and since the microscopic observation mechanism 3 is disposed on the third moving mechanism 23, the third moving mechanism 23 moves along the front-rear direction, so that the microscopic observation mechanism 3 can be driven to move along the front-rear direction. In the process of moving the microscopic observation mechanism 3 along the vertical direction and along the front-back direction, the visual field of the microscopic observation mechanism 3 can be accurately aligned to a specific position on the test piece, so that the test piece can be observed conveniently.
Meanwhile, the third moving mechanism 23 is provided in the left-right direction, and when the microscopic observation mechanism 3 slides with respect to the third moving mechanism 23, the microscopic observation mechanism 3 moves in the left-right direction.

When only one clip 1 is provided, the first moving mechanism 21 has a cantilever structure, and the second moving mechanism 22, the third moving mechanism 23, and the microscopic observation mechanism 3 are provided on the first moving mechanism 21, so that an eccentric load is easily generated on the first moving mechanism 21, which results in deformation of the first moving mechanism 21, and structural instability of the second moving mechanism 22, the third moving mechanism 23, and the microscopic observation mechanism 3, which affects accuracy of observation data of the microscopic observation mechanism 3.
In this embodiment, two clips 1 are provided on the upright, and the upper and lower ends of the first moving mechanism 21 are respectively connected to one of the clips 1, so that the upper and lower ends of the first moving mechanism 21 can be simultaneously assembled on the upright. From this, set up two clamps 1 on the stand to with the upper and lower both ends of first moving mechanism 21 respectively with one of them clamp 1 be connected, can promote the rigidity of first moving mechanism 21, second moving mechanism 22, third moving mechanism 23 and microscopic observation mechanism 3 set up on first moving mechanism 21, be difficult to make first moving mechanism 21 take place to warp, thereby guarantee second moving mechanism 22, third moving mechanism 23 and microscopic observation mechanism 3's structural stability, and then guarantee microscopic observation mechanism 3's observation data's accuracy.
Preferably, the clip 1 is made of nylon material.

Meanwhile, both collars 11 are provided in a semicircular shape. In addition, a spring washer is arranged on the bolt, and the spring washer is positioned between the nut and the lantern ring 11.
In the present embodiment, two collars 11 are oppositely provided on the column, and bolts are used to pass through the screw holes to connect the two collars 11. When the test piece is observed in the experimental process, the bolts are screwed, friction force between the lantern ring 11 and the upright post is increased, the lantern ring 11 is prevented from sliding on the upright post, stability of the clamp 1 is improved, and stability of the microscopic observation mechanism 3 is further improved.

Before the clamp 1 is sleeved, rough fillers such as paper adhesive tapes and electrical adhesive tapes are arranged on the stand columns in advance, and then, when the clamp 1 is sleeved, the clamp 1 is sleeved in an area on the stand columns, where the rough fillers such as the paper adhesive tapes and the electrical adhesive tapes are arranged, the friction coefficient between the clamp 1 and the rough fillers such as the paper adhesive tapes and the electrical adhesive tapes is large, the friction force is also large, the clamp 1 can be prevented from sliding on the stand columns, and the stability of a mobile platform is convenient to guarantee.
