[0021] The following will be further described in detail with reference to the attached Figure 1 —5 to this application.

[0022] A new type of sample holder connecting device includes a sample stage 1 and a transfer rod 2.

[0023] A through hole 3 and a placement hole 4 are provided on the sample stage 1. A through groove 5 is provided on the through hole 3, and a guide groove 6 is provided in the placement hole 4; a mounting table 7 is provided in the placement hole 4: a threaded hole 8 is provided in the placement hole 4, a positioning hole 9 is provided on the mounting table 7, a counterbore 10 is provided on the positioning hole 9, and a connecting bolt 11 is placed in the counterbore 10. The connecting bolt 11 passes through the positioning hole 9 and is threadedly connected to the threaded hole 8. Through the setting of the split mounting table 7, the production and manufacturing process of the sample holder is simplified.

[0024] A limit pin 16 corresponding to the through groove 5 is fixedly provided on the transfer rod 2; a guide block 17 is fixedly provided at one end of the transfer rod 2 close to the limit pin 16. The setting of the limit pin 16 enables the transfer rod 2 to be fixed in the sample holder, and the setting of the guide block 17 plays a guiding role when the transfer rod 2 is inserted into the sample holder, facilitating installation.

[0025] A relief hole 12 is provided on the mounting table 7. A limit table 13 is fixedly provided in the relief hole 12. A first relief groove 14 and a second relief groove 15 are provided on the limit table 13. The first relief groove 14 and the second relief groove 15 are oppositely arranged at both ends of the limit table 13, and the through groove 5 is collinear with the first relief groove 14. The setting of the relief hole 12 enables the limit pin 16 to rotate in the relief hole 12. At the same time, the settings of the first relief groove 14 and the second relief groove 15 play a guiding and restricting role respectively, enabling the transfer rod 2 to be installed on the sample holder.

[0026] The sample stage 1 is provided with a mounting hole 18, and an internal thread 19 is provided in the mounting hole 18. The mounting hole 18 and the through hole 3 are coaxially arranged; a stop block 20 is fixedly arranged in the mounting hole 18, a pressing block 21 is slidably arranged on the stop block 20, a limiting block 22 is fixedly arranged on the pressing block 21, and the limiting block 22 is located on the side of the stop block 20 away from the through hole 3; a set screw 23 is threadedly connected to the internal thread 19, and a spring 24 is placed in the mounting hole 18. The spring 24 is located between the set screw 23 and the limiting block 22. The pressing block 21 is pushed by the spring 24 to exert a force on the transfer rod 2, so that when the limit pin 16 is placed in the second relief groove 15, the placement state of the limit pin 16 is more stable.

[0027] When the transfer rod 2 is inserted into the sample stage 1, after the limit pin 16 passes through the through slot 5 and the first relief groove 14, when the transfer rod 2 rotates 180° axially, the pressing block 21 presses against the guiding block 17, so that the limit pin 16 presses against the second relief groove 15.

[0028] The implementation principle of this embodiment is as follows: When installing the sample rack, the transfer rod 2 and the through hole 3 are coaxially arranged, and after the limit pin 16 corresponds to the through slot 5, the transfer rod 2 is inserted into the sample rack, so that the limit pin 16 sequentially passes through the through slot 5 and the first limit groove and then enters the relief hole 12; at this time, the guiding block 17 presses against the pressing block 21 and pushes the pressing block 21 in the direction close to the set screw 23, and the pressing block 21 and the set screw 23 compress the spring 24; then the transfer rod 2 rotates 180° axially, so that the limit pin 16 is aligned with the second relief groove 15. At the same time, the spring 24 restores and pushes the pressing block 21 to move away from the set screw 23, so that the guiding block 17 drives the limit pin 16 on the transfer rod 2 to move in the direction of the second relief groove 15, and the limit pin 16 presses against the second relief groove 15, completing the connection between the sample rack and the transfer rod 2; when disassembling, push the transfer rod 2 in the direction close to the set screw 23, so that the limit pin 16 is separated from the contact with the second relief groove 15, and then rotate the transfer rod 2 180° axially, so that the limit pin 16 is aligned with the first relief groove 14, and then the drive rod can be pulled out to withdraw it from the sample rack, completing the disassembly of the two.

[0029] Through the setting of the mounting platform 7, when connecting the sample rack and the transfer rod 2, the second relief groove 15 on the mounting platform 7 can limit the limit pin 16. At the same time, the pressing block 21 is pressed against the transfer rod 2 by the spring 24, so that the limit pin 16 presses against the second relief groove 15, optimizing the connection method between the sample rack and the transfer rod 2, and having the advantage of improving the installation process of the sample rack.
