[0002] The scanning electron microscope is a powerful and widely used instrument for material characterization and observation. It is mainly used to magnify and observe the surface structure of objects. Specifically, it uses a focused electron beam to scan the sample surface and measure the various physical signals generated to observe the sample. The placement table of the scanning electron microscope is a platform for placing samples to ensure that the samples can be correctly aligned for observation and analysis.

[0003] However, the existing placement table is multifunctional and simple, and can only simply carry samples. During use, the samples are quite diverse. For some samples, the sample size is small and it is difficult to operate and fix them. Especially when fixing the fracture samples, the fracture samples themselves are thin and need to be placed vertically. Therefore, it is difficult to fix them, which is not conducive to operation and use by relevant personnel.

[0004] In view of this, the present utility model is proposed. Utility Model Content

A connecting block 101 which is fixedly connected to a scanning electron microscope device is provided at the bottom of the table body 1. The connecting block 101 is a connecting part for docking and installing with the device. When operating the device, the connecting block 101 needs to be installed at a specified position. A clamping groove 102 is provided on the upper surface of the table body 1. The table body 1 also comprises a clamping assembly 2 which can be installed in the clamping groove 102. The clamping groove 102 is used to limit the position of the clamping assembly 2 to avoid displacement of the sample. The clamping assembly 2 comprises a clamping base 201. An elastic sheet 202 for fixing the fracture sample is provided on the clamping base 201. The elastic sheet 202 can clamp and fix the sample by its own elasticity. An operating panel 203 is provided on the side wall of the elastic sheet 202. The operating panel 203 is used to assist a user in applying force so as to deform the elastic sheet 202. An auxiliary mechanism 3 is provided at the center of the upper surface of the table body 1. The auxiliary mechanism 3 is used for further auxiliary operation. An auxiliary clamping groove 103 for limiting the position of the clamping assembly 2 is provided next to the auxiliary mechanism 3.

[0027] The auxiliary mechanism 3 includes a rotating rod 301, on the outer wall of which a limiting plate 302 and a force plate 303 are fixed, a rotating seat is fixed on the platform 1, the rotating rod 301 is slidably engaged on the side wall of the rotating seat, and a limiting piece 304 is fixed on the rotating seat for allowing the limiting plate 302 to be engaged, so that it is convenient to apply force to the elastic sheet 202 and limit and fix the elastic sheet 202.

[0028] The bottom of the clamping base 201 extends to both sides to form a dovetail shape, an operating notch is provided on the operating plate 203, one side of the clamping base 201 extends upward to form a side back plate 204, a side pad is fixed on the side back plate 204, and the side pad can be used as a reference surface for the vertical reference of the reference sample, so that the clamping base 201 can be easily fixed to prevent the clamping base 201 from falling off, and a follower plate 205 for maintaining the vertical fracture sample is rotatably installed on the side wall of the elastic sheet 202 close to the side back plate 204, so as to prevent the clamping The sample is subjected to excessive force locally, and a clamping column 4 is rotatably installed on the side wall in the clamping groove 102. A side clamping groove corresponding to the bottom shape of the clamping base 201 is opened on the outer wall of the clamping column 4. Part of the outer wall of the clamping column 4 protrudes from the upper surface of the platform 1, which can make it more convenient to clamp and fix the clamping component 2. Magnetic sheets 5 are fixed in the side clamping groove and at the bottom of the clamping groove 102, and a magnetic suction part that attracts the magnetic sheet 5 is fixed to the bottom of the clamping base 201, which can conveniently restrict the clamping base 201.

[0029] When the utility model is in use, the clamping assembly 2 is first placed in the auxiliary card slot 103, the force plate 303 on the auxiliary mechanism 3 is slid into the operating notch on the operating plate 203, and then the operating plate 203 is rotated to force the elastic sheet 202 to open. At this time, the force plate 303 can be further rotated so that the limit plate 302 can be clamped by the limit member 304, so that the elastic sheet 202 can be maintained in the open state, and then the fracture sample is placed between the follower plate 205 and the side pad on the elastic sheet 202. When clamping, The follower plate 205 can fit with the side wall of the sample, so that the force on the sample is more uniform. The operation is relatively simple and easy to use when clamping or placing. When the clamping component 2 needs to be taken out, the force plate 303 can be moved to separate it from the operating plate 203. The magnetic suction part at the bottom of the clamping base 201 can attract the magnetic sheet 5. When it is moved above the clamping column 4, the side clamping slot can be rotated so that the side clamping slot faces upward, so as to facilitate the placement of the clamping component 2, and the magnetic sheet 5 at the bottom of the side clamping slot and the clamping groove 102 can jointly fix the position of the clamping component 2.

[0030] Example 2

[0031] In this embodiment, the method of fixing the clamping assembly 2 in the clamping groove 102 is changed, so as to further prevent the clamping assembly 2 from being displaced.

[0032] The table body 1 also includes a center table 104 rotatably installed at the center of the table body 1, and the auxiliary mechanism 3 is fixed on the center table 104. The clamping groove 102 is a dovetail groove that adapts to the shape of the clamping base 201, and the clamping groove 102 extends toward the center table 104. One side of the auxiliary clamping groove 103 passes through the center table 104, which can facilitate the smooth transfer of the clamping component 2 to the clamping groove 102. A filling plate 206 is fixed to the bottom of the clamping base 201, and an arc-shaped surface is provided on the side wall of the filling plate 206, which can fit the side wall of the center table 104, so as to limit the movement of the clamping component 2. After the center table 104 rotates, the clamping groove 102 and the auxiliary clamping groove 103 are no longer completely connected to each other. At this time, the filling plate 206 can be blocked by the outer wall of the center table 104, thereby avoiding the displacement of the clamping base 201.

[0033] When in use, the sample is fixed on the clamping assembly 2 using the auxiliary mechanism 3, and then the clamping assembly 2 is directly pushed away from the center table 104, so that the clamping assembly 2 enters the snap-in groove 102. After the center table 104 continues to rotate, the filling plate 206 can be used to block the movement of the clamping base 201, so that the clamping assembly 2 is completely fixed.

[0034] The utility model can facilitate operators to clamp and fix the fracture sample by utilizing the clamping assembly 2, and the clamping assembly 2 can also better protect the fracture sample. When fixing the clamping assembly 2 on the platform 1, it is also easy to operate. The clamping assembly 2 can be directly clamped in the clamping groove 102, which effectively reduces the difficulty of placing the fracture sample.
