[0030] like Figures 1 to 5As shown, an automated sample tube liquid dispensing device includes a main unit 1 with a display screen 2. The main unit 1 is used to dispense liquid into the tube. One end of the main unit 1 is mechanically connected to a connecting block 3. One end of the connecting block 3 is provided with a bevel 4 with several first magnetic elements 5, and the other end of the connecting block 3 is provided with an abutment block 6. The display screen 2 is snapped onto one side of the connecting block 3. A connecting shell 9 is screwed onto one side of the display screen 2. One end of the connecting shell 9 is provided with a groove 8 with several second magnetic elements 7, and the other end of the connecting shell 9 is provided with a fixing block 11 with a fixing groove 10. There is an angle of 100° to 120° between the fixing block 11 and the groove 8. The connecting shell 9 is made of plastic. The fixing groove 10 is used to insert into the abutment block 6. There is a magnetic attraction between the first magnetic elements 5 and the second magnetic elements 7. The groove 8 is inserted into the connecting block 3. The display screen 2 is mounted on the main unit 1 at an angle through the bevel 4. In this embodiment, the included angle between the fixing block 11 and the groove 8 is complementary to the tilt angle of the inclined surface 4. That is, the included angle and the tilt angle of the inclined surface 4 are complementary angles, so that while the inclined surface 4 and the groove 8 abut against each other, the connecting block 3 can stably cover one end of the connecting block 3. By setting the magnetic adsorption of the first magnetic component 5 and the second magnetic component 7, combined with the insertion of the abutting block 6 and the fixing groove 10, the display screen 2 is tilted and assembled on one end of the host 1. The tilt angle of the display screen 2 is the tilt angle of the inclined surface 4. On the one hand, it is convenient to observe the data on the display screen 2, and on the other hand, it is convenient for the user to position, disassemble or assemble the display screen 2, reducing the difficulty of disassembling and assembling the display screen 2.

[0031] Specifically, the display screen 2 is a touch-operated CNC screen. The display screen 2 has a shielded cavity 20 with a first main control board 12. The shielded cavity 20 is made of silicon steel sheet. The host 1 has a second main control board 13. One end of the abutment block 6 has a power receiving block 14 that is wired to the second main control board 13. The groove 8 has an electronic receiving slot 15 that is wired to the second main control board 13. The power receiving block 14 is used to insert into the electronic receiving slot 15. The power receiving block 14 is inserted into the abutment block 6 through the fixing slot 10, so that the power receiving block 14 and the electronic receiving slot 15 are inserted, thereby enabling the display screen 2 and the host 1 to be powered, and enabling the first main control board 12 and the second main control board 13 to achieve data connection. This allows the user to control the operation of this embodiment through the display screen 2. It should be noted that the display screen 2 has a battery 17 that is wired to the first main control board 12. In actual use, the disassembled display screen 2 can become an independent database. The user can continue to use and query the data stored in the first main control board 12, which is convenient for the user.

[0032] It is worth noting that the plane of the connecting block 3 is parallel to the plane of the fixing block 11. Both the connecting block 3 and the fixing block 11 are made of plastic. The abutting block 6 is perpendicular to the connecting block 3, and the cross-sectional shape of the abutting block 6 is a rounded rectangle, which facilitates the insertion of the abutting block 6 into the fixing groove 10. It should be further explained that a rubber film 60 is adhered to the abutting block 6. In this embodiment, the rubber film is adhered to the periphery of the abutting block 6, which can further enhance the friction between the inner wall of the fixing groove 10 and the abutting block 6, and enhance the connection structure strength between the abutting block 6 and the fixing groove 10.

[0033] At least four first magnetic components 5 are provided. In this embodiment, the four first magnetic components 5 are evenly distributed in a rectangular shape on the groove 8. The first magnetic components 5 are permanent magnets, and the cross-sectional shape of the first magnetic components 5 is semi-circular. At least four second magnetic components 7 are provided. In this embodiment, the four second magnetic components 7 are evenly distributed in a rectangular shape on the inclined surface 4. The second magnetic components 7 are iron magnetic grooves, and the second magnetic components 7 are distributed one-to-one with the first magnetic components 5 to avoid skew or offset when the user assembles the display screen 2, thereby improving the positioning and connection effect. It should be noted that in this embodiment, the first magnetic components 5 can be exposed in the groove 8, or hollow spherical protrusions can be provided in the groove 8 to hold the first magnetic components 5 in place, preventing damage and enhancing the service life of this embodiment.

[0034] One end of the host 1 is provided with a power cord 18, and the host 1 is also provided with a power switch 16. The power cord 18 and the power switch 16 are both wired to the second main control board 13. By setting the power cord 18, the host 1 can be connected to an external power source to supply power to the host 1. By setting the power switch 16, it is convenient for users to start and stop this embodiment.

[0035] Working principle: Connecting block 3 is horizontally inserted into groove 8, limiting the connection position of connecting block 3 on display screen 2, so that inclined surface 4 abuts against one end of groove 8, and several first magnetic parts 5 and several second magnetic parts 7 are magnetically connected one-to-one, and display screen 2 is tilted on host 1; at the same time, abutting block 6 is vertically inserted into fixing groove 10, so that power receiving block 14 and power receiving groove 15 are connected and powered, thereby powering display screen 2 and host 1, and enabling data connection between first main control board 12 and second main control board 13.
