[0021] 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.

[0022] Example 1:

[0023] Please see Figure 1-5 This utility model provides a technical solution: an adjustable length medical scraper, including a handle 1, an adjusting post 2, and a scraper body 3. One end of the handle 1 has a sliding hole 11, and the adjusting post 2 is slidably inserted into the sliding hole 11. One end of the adjusting post 2 located inside the sliding hole 11 has an inner elongated hole 21. A lead screw 12 is horizontally rotatably connected inside the sliding hole 11. A threaded sleeve 22 is fixedly connected to the end of the inner elongated hole 21. The lead screw 12 is threadedly connected to the threaded sleeve 22. A rotating head 14 is fixedly connected to the end of the lead screw 12. The rotating head 14 passes through the end of the handle 1. By rotating the rotating head 14, the position of the adjusting post 2 can be adjusted, thereby adjusting the overall length, which is convenient for operation and more flexible.

[0024] The spoon body 3 is located on the end of the adjusting post 2 away from the handle 1. The adjusting post 2 away from the handle 1 has an insertion hole 24, and the end of the insertion hole 24 has a square opening 25. The side wall of the spoon body 3 is fixed to the insertion post 31, and the end of the insertion post 31 is fixed to the square post 32. The insertion post 31 is inserted into the insertion hole 24, and the square post 32 is inserted into the square opening 25. The spoon body 3 can be easily installed on the end of the adjusting post 2, which is convenient for replacing different types of spoon bodies and is more practical.

[0025] Example 2:

[0026] Please see Figure 1-5This is the second embodiment of the present invention. Based on the previous embodiment, a circular cavity 17 is provided inside the end of the handle 1 near the shaft 13. A ratchet ring 18 is rotatably connected inside the circular cavity 17. A small ratchet 19 is fixedly sleeved inside the circular cavity 17. A rotating head 14 is fixedly connected to one end of the shaft 13 outside the handle 1. A handle 15 is rotatably connected to the end of the rotating head 14. Two limiting side grooves 16 are provided on both sides of the sliding hole 11. Two limiting blocks 23 are fixedly connected to one end of the adjusting column 2 inside the sliding hole 11. The limiting blocks 23 are slidably connected to the limiting side grooves 16. When the handle 15 is rotated to a state perpendicular to the rotating head 14, it can be rotated with less effort.

[0027] Multiple first ratchet springs 110 are uniformly fixed to the side wall of the circular cavity 17. The first ratchet springs 110 engage with any ratchet tooth of the ratchet ring 18. Multiple second ratchet springs 111 are uniformly fixed to the inner side wall of the ratchet ring 18. The second ratchet springs 111 engage with any ratchet tooth of the small ratchet 19. The ratchet teeth on the small ratchet 19 face opposite directions to the ratchet teeth on the ratchet ring 18. The double ratchet structure allows the shaft post 13 to rotate freely in both directions. When the shaft post 13 stops, it is locked by the two sets of ratchet springs to prevent the shaft post 13 from rotating on its own.

[0028] A chamber 26 is opened at the end of the adjusting column 2 near the square opening 25. Two columns 28 are vertically fixed to both sides of the chamber 26 near the square opening 25. The columns 28 are rotatably connected to the rotating rod 29.

[0029] Inside the adjusting column 2, two fan-shaped openings 27 are opened on both sides of the square opening 25. The fan-shaped openings 27 are connected to the square opening 25 and the chamber 26. The end of the rotating rod 29 is slidably connected to the fan-shaped opening 27. The end of the rotating rod 29 is fixedly connected to the insert block 212 on the side near the square opening 25. Two positioning openings 33 are opened on both sides of the square column 32. The insert block 212 is inserted into the positioning opening 33. The side of the insert block 212 near the spoon body 3 is arc-shaped.

[0030] A torsion spring 210 is fixed at the rotatable connection between the column 28 and the rotating rod 29. A button 211 is fixed to one side wall of the rotating rod 29 located in the chamber 26. A damping sleeve 215 is fixed to the inner side wall of the insertion hole 24. The damping sleeve 215 is sleeved on the insertion post 31. A limiting plate 213 is fixed to one end of the rotating rod 29 located in the fan-shaped opening 27. An arc-shaped groove 214 is opened on the side wall of the fan-shaped opening 27. The limiting plate 213 is slidably connected to the arc-shaped groove 214. By pressing the two buttons 211, the insertion block 212 can be moved away from the positioning port 33, making it easy to pull out the square column 32 and replace the spoon body 3.

[0031] Example 3:

[0032] Please see Figure 1-5This is the third embodiment of the present invention, which is based on the above two embodiments. When using the present invention, rotating the handle 15 drives the shaft 13 to rotate, thereby adjusting the position of the adjusting column 2 to make the overall length appropriate. When the spoon body 3 needs to be replaced, pressing the two buttons 211 can make the insert 212 leave the positioning port 33 and pull out the square column 32. When installing the spoon body 3, the square column 32 is inserted into the square port 25. When inserted, the square column 32 presses the arc surface of the insert 212, causing the rotating rod 29 to rotate. When inserted to the bottom, the rotating rod 29 returns to its original position under the action of the torsion spring 210, and the insert 212 is inserted into the positioning port 33 to achieve fixation. The position of the adjusting column 2 of the present invention is adjustable, thereby adjusting the overall length, which is convenient for operation. The spoon body 3 is fixed to the end of the adjusting column 2 by plugging and snapping, which is convenient for replacement and more practical.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
