[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4In this embodiment of the present invention, an automatic sample preparation device for a protective tube includes a first C-shaped plate 1, with second C-shaped plates 2 symmetrically arranged on both sides of the first C-shaped plate 1. A protective tube is provided inside both the first C-shaped plate 1 and the second C-shaped plate 2. Four supporting guide wheels 3 are symmetrically and rotatably mounted on the side of the second C-shaped plates 2 that are far apart from each other. A movable C-shaped seat 4 is rotatably connected between the supporting guide wheels 3. A driving mechanism is provided outside the movable C-shaped seat 4. A sliding conductive component is provided between the movable C-shaped seat 4 and the second C-shaped plate 2. A mounting base 5 is fixedly connected to the inner side of the movable C-shaped seat 4. A first electric push rod 6 is fixedly mounted on the mounting base 5. The telescopic end of the first electric push rod 6 slides through the mounting base 5 and is fixedly connected to a movable seat 7. A cutter 8 is fixedly connected to the movable seat 7. A first guide rod 9 is symmetrically fixedly connected to the movable seat 7. The first guide rod 9 slides through the mounting base 5. A circular hole for the first guide rod 9 to slide through is symmetrically opened on the mounting base 5.

[0025] Driven by a drive mechanism, the movable C-shaped seat 4 reciprocates under the action of the support guide wheel 3, thereby cutting the protective tube located in the first C-shaped plate 1 and the second C-shaped plate 2 by the cutter 8. During cutting, the movable seat 7 is moved by the first electric push rod 6, so that the cutter 8 can be inserted into the protective tube and gradually cut off the protective tube. Electric cutting is more labor-saving, and mechanical rotation cutting results in a neater cut surface.

[0026] The drive mechanism includes symmetrically arranged drive gears 10, and a first sprocket 11 and a second sprocket 12 arranged flush. The drive gears 10 are rotatably mounted on the opposite side of the second C-shaped plate 2. The movable C-shaped seat 4 has a toothed groove 13, which meshes with the drive gear 10 for transmission. A third sprocket 14 is concentrically mounted on the drive gear 10. The third sprocket 14, the first sprocket 11, and the second sprocket 12 are all connected by a chain 15 for transmission. The first sprocket 11 serves as a support and guide. Both the first sprocket 11 and the second sprocket 12 are rotatably connected to the second C-shaped plate 2.

[0027] The shaft ends of the second sprocket 12 are respectively fixedly connected to an external spline shaft 16 and an internal spline shaft 17. The internal spline shaft 17 is simultaneously rotatably connected to the corresponding second C-shaped plate 2 and the first C-shaped plate 1. The external spline shaft 16 is rotatably connected to the corresponding second C-shaped plate 2. One end of the external spline shaft 16 is inserted into the internal spline shaft 17 and slidably connected.

[0028] One end of the internal spline shaft 17 is fixedly connected to a first gear 18. The first gear 18 is externally provided with a second gear 19 that meshes with it for transmission. The second gear 19 is fixedly connected to the output end of the motor 20. The motor 20 is fixedly mounted on the first C-shaped plate 1.

[0029] The first sprocket 11, the second sprocket 12 and the third sprocket 14 work together to drive the two drive gears 10 simultaneously, thus creating a stable driving effect on the movable C-shaped seat 4. The two second sprockets 12 are connected as a whole by the external spline shaft 16 and the internal spline shaft 17, and are driven by the motor 20 in conjunction with the first gear 18 and the second gear 19. Thus, the movable C-shaped seats 4 on both sides can be driven simultaneously by one motor 20, making the mechanism more optimized.

[0030] A handle 21 is fixedly installed on the first C-shaped plate 1.

[0031] The handle 21 makes it easy to hold the device as a whole.

[0032] An adjusting sleeve 22 is fixedly connected to the first C-shaped plate 1 and one of the second C-shaped plates 2. An adjusting rod 23 is fixedly connected to the other second C-shaped plate 2. The adjusting rod 23 is provided with a scale line 24. The adjusting rod 23 is inserted into the adjusting sleeve 22 and is slidably connected to the adjusting sleeve 22. A hand-tightening bolt 25 is threadedly connected to the adjusting sleeve 22. The hand-tightening bolt 25 is inserted into the adjusting sleeve 22 and abuts against the adjusting rod 23. The adjusting sleeve 22 is provided with a threaded hole for threaded connection of the hand-tightening bolt 25.

[0033] The top of the first C-shaped plate 1 is symmetrically and fixedly connected with a second electric push rod 26. The telescopic ends of the second electric push rod 26 are fixedly connected with a clamp 27. The two sides of the clamp 27 are symmetrically and fixedly connected with a second guide rod 28. An auxiliary sleeve 29 is slidably sleeved on the outer side of the second guide rod 28. The auxiliary sleeve 29 is fixedly connected to the side wall of the first C-shaped plate 1.

[0034] One of the second C-shaped plates 2 is fixed at a distance from the first C-shaped plate 1, while the other second C-shaped plate 2 can have its spacing adjusted by the cooperation of the adjusting sleeve 22 and the adjusting rod 23, thereby controlling the length of the sample.

[0035] A base plate 30 is fixedly connected between the first C-shaped plate 1 and one of the second C-shaped plates 2. A mobile power supply 31 is installed on the base plate 30. A switch 32 is installed on the mobile power supply 31. The switch 32 is electrically connected to the mobile power supply 31. The first electric push rod 6, the motor 20, and the second electric push rod 26 are all electrically connected to the switch 32.

[0036] The working principle of this utility model is as follows:

[0037] In use, the adjusting rod 23 slides within the adjusting sleeve 22, controlling the distance between the two second C-shaped plates 2 in conjunction with the scale line 24, and is locked in place by the hand-tightening bolt 25. During this process, the outer spline shaft 16 and the inner spline shaft 17 slide against each other, thus achieving synchronous extension and retraction. Holding the handle 21, the device is secured to the outside of the protective tube. The second electric push rod 26 is activated, and under the guidance of the second guide rod 28 and the auxiliary sleeve 29, the clamp 27 clamps and fixes the protective tube, making the C-shaped plate concentric with the protective tube. At this time, the motor 20 is activated, and the motor 20 passes through the first tooth... The engagement of wheel 18 and second gear 19 drives the inner spline shaft 17 to rotate, thereby synchronously driving the outer spline shaft 16 to rotate, which in turn causes the second sprocket 12 to rotate, which in turn drives the third sprocket 14 to rotate via chain 15, which in turn drives the drive gear 10 to rotate, which in turn drives the movable C-shaped seat 4 to roll within the support guide wheel 3 via tooth groove 13. The forward and reverse rotation of motor 20 controls the reciprocating rotation of the movable C-shaped seat 4. At this time, the first electric push rod 6 drives the movable seat 7 to move, thereby bringing the cutter 8 close to the protective tube and cutting the protective tube, thus performing sample preparation.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
