[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 4 , a data entry device for marking metallographic samples, comprising a shell 1, one side of the shell 1 is rotatably connected to two door panels 2, one side of the two door panels 2 is provided with an observation window 3 for observing the internal marking situation, a marking machine 4 is provided on the top inner wall of the shell 1, the top inner wall of the shell 1 is fixed with two fixing frames 5 and two guide frames 6 by bolts, a slide 9 is slidably connected in the guide frame 6, one end of the slide 9 is provided with a groove, a ball 15 is rollingly connected in the groove, and the ball 15 can contact the door panel 2, a camera 13 is rotatably connected between the inner walls of the two sides of the two fixing frames 5, one side of the two fixing frames 5 is rotatably connected to a winding roller 10 through a connecting shaft, and the connecting shaft passes through the fixing frame 5 and is fixed to the camera 13, a torsion spring 11 is fixed to one side of the connecting shaft by bolts, and the torsion spring 11 is fixed to the torsion spring 11 by bolts, and the torsion spring 11 is fixed to the torsion spring 11 by bolts. The spring 11 is fixed to the fixed frame 5, and a pull rope 8 is fixed to the outer side of the circumference of the winding roller 10 by bolts, and the pull rope 8 is fixed to the slide 9. A tension spring 14 is welded on one side of the slide 9, and the tension spring 14 is fixed to the guide frame 6, and the tension of the tension spring 14 is much greater than the torque generated by the torsion spring 11. When marking, the door panel 2 is in a closed state. At the same time, the torsion spring 11 will make the lens of the camera 13 and the laser generated by the marking machine 4 face each other, avoiding damage to the lens by the laser, thereby improving the protection effect of the device. When recording is required, the door panel 2 is opened, and the deformed tension spring 14 recovers and drives the slide 9 to slide in the guide frame 6, so that the pull rope 8 drives the winding roller 10 to rotate, and then drives the camera 13 to rotate, so that the lens of the camera 13 is directed to the marked sample, thereby recording and collecting the sample.

[0025] In order to facilitate the camera 13 to better record samples, a screw rod 16 is also provided. The screw rod 16 is rotatably connected to one side of the bottom of the guide frame 6. The circumferential outer wall of the screw rod 16 is threadedly connected with a block 18, and the block 18 is slidably connected to the guide frame 6. One end of the screw rod 16 passes through the guide frame 6 and is fixed with a turning handle 19 by bolts. The turning handle 19 drives the screw rod 16 to rotate, so that the block 18 slides in the guide frame 6, and then the position of the block 18 is adjusted. A sponge pad 17 is bonded to one side of the block 18, and the sponge pad 17 can contact the slide 9. After opening the door panel 2, one side of the slide 9 will impact the block 18, and the sponge pad 17 absorbs the impact force to prevent the thread from being damaged by excessive impact force. After adjusting the position of the block 18, the sliding distance of the slide 9 can be blocked, thereby changing the rotation angle of the camera 13, thereby realizing the recording of different samples, and improving the recording effect of the device.

[0026] In order to further protect the lens of the camera 13, a cover frame 12 is also provided. One end of the cover frame 12 passes through the fixing frame 5 and is slidably connected to the fixing frame 5. The cover frame 12 is in contact with the lens of the camera 13 and can block the lens of the camera 13, thereby reducing the influence of the laser generated by the marking machine 4 when marking on the lens. At the same time, the rotation of the camera 13 will squeeze the cover frame 12 to slide upward, thereby avoiding affecting the rotation of the camera 13, further improving the protection effect of the device.

[0027] In addition, a mounting groove is provided on one side of the two fixing frames 5, in which a pulley 7 is rotatably connected, and the pulley 7 is wound around the pull rope 8, which reduces the friction between the pull rope 8 and the fixing frames 5 and prolongs the service life of the pull rope 8.

[0028] Finally, it should be noted that: for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included in the protection scope of this utility model.
