[0002] A microscope is an optical instrument composed of a lens or a combination of several lenses. It is a symbol of mankind's entry into the atomic age. The microscope presents a whole new world to the human vision. For the first time, people saw hundreds of "new" tiny animals and plants, as well as the internal structure of various things from the human body to plant fibers. When dissecting an animal, the cell conditions of the animal can be clearly observed through a microscope. However, some microscopes require the base and the observation component to be assembled together when in use. Usually, the base is connected to the support column of the observation component. However, the fixing method between the two is generally relatively simple, and the stability of the connection between the two cannot be ensured. Because the microscope is a very precise instrument, the instability of the device connection will have a huge impact on the observation. At the same time, in order to enable the support column to meet the requirements of different installation heights of the observation component, the present application specifically proposes a stable base for an electron microscope.

[0016] The following will be combined Figure 1-3 The present invention is described in detail. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0017] A stable base for an electron microscope comprises a base 1, a lifting base 2 and a support column 3. A countersunk hole 4 is provided in the center of the base, and a group of relative slide grooves 5 are provided in the radial and axial directions with the countersunk hole as the center. The depth of the countersunk hole is greater than or equal to the depth of the slide groove. The lifting base is arranged directly above the countersunk hole and a first electric telescopic rod 6 which can be telescoped in the vertical direction is provided in the countersunk hole. One end of the first electric telescopic rod is connected to the bottom of the lifting base. At the same time, four support rods 7 which are evenly distributed along the circumference are fixedly connected to the bottom of the lifting base. The other end of each support rod away from the lifting base is connected to a slider 8. The slider is slidably connected in the slide groove. Several blocks 9 are provided at the bottom of the support column. Several slots 10 which match the blocks are provided at the top of the lifting base. At the same time, a brim 15 is provided at the bottom of the support column along the circumference. Several mounting holes 16 are provided on the brim. Bolts 17 are installed in each mounting hole. The lifting base is provided with threaded holes which match the bolts. The support column is connected to the base through a clamping mechanism.

[0018] Specifically, the clamping mechanism includes two groups of clamping components relatively arranged on both sides of the support column, each clamping component includes a mounting block 11, an electric screw 12, a second electric telescopic rod 13 and a clamping block 14, each mounting block is vertically fixed on the top side of the base, and a vertical electric screw is provided on the mounting block, a fixed block 18 is rotatably sleeved on the electric screw, a second electric telescopic rod that can be telescoped in the horizontal direction is fixedly connected to one side of the fixed block, and the other side of the fixed block is slidably connected to the mounting block, one end of the second electric telescopic rod that can be telescoped is fixedly connected to the clamping block, the two clamping blocks are relatively close to the clamping support column, and the clamping surface of the clamping block is set to be an arc surface that matches the support column.

[0019] The lifting seat is driven to automatically rise and fall by the first electric telescopic rod, thereby driving the linked support column to rise and fall to adjust the height to meet the requirements of different installation heights of the electron microscope observation components. During the lifting process, the support rod at the bottom of the lifting seat slides axially and radially to make the lifting seat rise and fall stably. In addition, the clamping block is loosened or clamped by the extension and retraction of the second electric telescopic rod. After the height is adjusted, the clamping block is driven by the movement of the electric screw to adjust to a suitable height to clamp the support column, which can maximize the stability of the entire device.

[0020] During the implementation process, first insert the block of the support column into the card slot of the lifting seat to engage it, and then combine the support column and the lifting seat into one by tightening the bolts, and then start the first electric telescopic rod to raise the lifting seat and adjust the height according to the actual installation height of the electron microscope observation component, thereby driving the support column to rise, and then start the electric screw to raise the clamping block to a suitable force height, and finally start the second electric telescopic rod to move until the clamping block clamps the support column. After use, the second electric telescopic rod moves again, the telescopic rod retracts to drive the clamping block to loosen the support column, and the movement of the first electric telescopic rod drives the lifting seat to descend and wait for the next use.
