The bottom of the back plate 12 is fixedly connected to the top of the platform 2, and a pressure plate 13 fitted on the top of the platform 2 is arranged on one side of the back plate 12. The bottom of the pressure plate 13 is fixedly connected to the sleeve 22, and the outer wall of the sleeve 22 is slidably engaged with the top through hole of the platform 2 and the upper cavity. The sleeve 22 can move in the top through hole of the platform 2, and the inner side of the sleeve 22 is threadedly connected to the screw 21. The outer side of the screw 21 is rotatably connected to the top of the platform 2 through a bearing, and the screw 21 can rotate through the bearing;

[0025] Specifically, when using the sample pressing rod device for the direct reading spectrometer, the user can place the sample on the inner side of the back plate 12 and the pressing plate 13, and then rotate the screw 21. When rotating, the screw 21 can drive the pressing plate 13 to move and fix the sample to prevent the sample from moving during stamping.
[0026] Embodiment 2: By Figure 1-3 It can be seen that a round sleeve 3 is fixedly connected to the outside of the body 1, and round rods 4 are fixedly connected to the upper and lower sides of the round sleeve 3. The outer sides of the two round rods 4 are rotatably connected to a bent plate 5 through a bearing. The bent plate 5 can rotate through the bearing. A vertical cylinder 7 is fixedly connected to one side of the bent plate 5. A slider 8 is movably connected to the inside of the vertical cylinder 7. The slider 8 can move inside the vertical cylinder 7. The bottom of the slider 8 is fixedly connected to the top of the pressure rod 10, and the bottom of the pressure rod 10 fits with the top of the conical pressure head 15.
[0027] In the specific implementation process, it is worth pointing out that the user can pull the slider 8 downward to indirectly drive the pressure rod 10 and the conical pressure head 15 to move downward;
[0028] Furthermore, a handle 9 is fixedly connected to the outer side of the slider 8, and the outer side of the handle 9 is movably connected to the side through hole of the vertical tube 7;
[0029] In the specific implementation process, it is worth pointing out that the handle 9 is convenient for the user to pull the slider 8 up and down;
[0030] Furthermore, the outer side of the round rod 4 is movably connected to a first spring 6, and the two ends of the first spring 6 are respectively fixedly connected to the inner side of the bent plate 5 and one end of the round sleeve 3, and the outer side of the pressure rod 10 is movably connected to a second spring 11, and the two ends of the second spring 11 are respectively fixedly connected to the bottom of the slider 8 and the inner lower side of the vertical tube 7;
[0031] In the specific implementation process, it is worth pointing out that the device can drive the bending plate 5 to automatically reset by relying on the elastic deformation of the first spring 6, wherein the second spring 11 can drive the conical pressure head 15 to automatically reset by relying on its own elastic deformation;
[0032] Further, a positioning rod 14 movably connected to the bottom groove of the pressure rod 10 is fixed to the top of the conical pressure head 15, a first annular plate 16 and a second annular plate 20 are respectively fixed to the lower outer wall of the pressure rod 10 and the outer wall of the conical pressure head 15, a rod body 17 is fixed to the bottom of the first annular plate 16, the lower outer wall of the rod body 17 is movably connected to the top groove of the second annular plate 20, the rod body 17 can move relatively in the top groove of the second annular plate 20, a clamping block 18 is movably connected to the lower outer side of the rod body 17, the outer side of the clamping block 18 is movably connected to the inner groove of the second annular plate 20, the clamping block 18 can be clamped in the groove of the second annular plate 20 for positioning, and one side of the clamping block 18 is fixedly connected to the inner groove of the second annular plate 20 through a rubber block 19;
[0033] In the specific implementation process, it is worth pointing out that after the second annular plate 20 and the rod body 17 are plugged into each other, the clamping block 18 can be clamped in the groove of the second annular plate 20 for positioning. When the second annular plate 20 is pulled out with force, the rubber block 19 is compressed to drive the clamping block 18 to break away from the side groove of the rod body 17. In daily use, the elastic deformation of the rubber block 19 can drive the clamping block 18 to be clamped in the side groove of the rod body 17 for positioning.
[0034] Specifically, based on the first embodiment, the cone pressing head 15 can be disassembled through the cooperation among the pressing rod 10, the cone pressing head 15 and the first annular plate 16, so that the user can replace the cone pressing head 15 of different sizes or a damaged cone pressing head 15 easily.
