[0026] In a further preferred embodiment of this utility model, the clamping mechanism includes a U-shaped frame 15, a bidirectional motor 16, a bidirectional screw 17, and two clamping rings 18. The U-shaped frame 15 is disposed on the fixed frame 4. The bidirectional motor 16 is fixedly installed on one side of the U-shaped frame 15. The bidirectional screw 17 is rotatably installed on the U-shaped frame 15. One end of the bidirectional screw 17 is fixedly connected to the output shaft of the bidirectional motor 16.

[0027] In this embodiment, the U-shaped frame 15 is mounted on the fixed frame 4 as the main support structure of the clamping mechanism. The bidirectional motor 16 is fixedly installed on one side of the U-shaped frame 15 as a power source to drive the bidirectional screw 17 to rotate. By rotating the bidirectional screw 17, the two clamping rings 18 can move synchronously towards or away from each other, thereby clamping or releasing the digestion bottle 10. This can ensure the stability of the digestion bottle 10 during digestion and facilitate the movement of the digestion bottle 10 to the atomic absorption spectrometer 2 after digestion.

[0030] In a further preferred embodiment of this utility model, a transverse motor 21 is fixedly installed on one side of the mounting bracket 3, and a transverse screw 22 is rotatably installed on the mounting bracket 3.

[0031] In this embodiment, the transverse motor 21 is fixedly installed on one side of the mounting frame 3 as a power source to drive the transverse screw 22 to rotate. The slide 23 is threaded onto the transverse screw 22 and slides against the inner wall of the mounting frame 3. Through the threaded transmission and the cooperation of the transverse screw 22, the transverse motor 21 can move in the transverse direction, and at the same time drive the fixed frame 4 and its components to move together. By driving the transverse screw 22 to rotate through the transverse motor 21, the transverse motor 21 can drive the slide 23 and its fixed components to move flexibly in the transverse direction, and drive the digestion bottle 10 to move automatically to the atomic absorption spectrometer 2 and tilt it.

[0033] In this embodiment, the mounting slot 24 is provided on the mounting frame 3 to provide a space for fixing and installing the photoelectric position sensor 25, while ensuring that the slide 23 can pass through the sensor and be accurately detected during movement. The photoelectric position sensor 25 is used to sense and detect the position of the slide 23. When the slide 23 moves under the drive of the transverse screw 22, the sensor can capture its position change and convert this information into an electrical signal for transmission and processing. When the slide 23 moves to the designated position, the photoelectric position sensor 25 sends a signal to stop the transverse motor 21, so that the digestion bottle 10 corresponds to the position of the atomic absorption spectrometer 2.

[0034] In a further preferred embodiment of the present invention, a rubber pad 26 for protecting the digestion bottle 10 is fixedly installed on the inner wall of the clamping ring 18.

[0035] In this embodiment, the rubber pad 26 is fixedly installed on the inner wall of the clamping ring 18. The rubber pad 26 is made of highly elastic rubber material, which can protect the digestion bottle 10 from scratches, wear or crushing damage that may occur when the clamping ring 18 clamps it directly. It can provide a buffer layer between the clamping ring 18 and the digestion bottle 10 to reduce direct contact between the two.
