[0071] The working principle of the utility model will be introduced below to better understand the utility model:

[0072] When the angle between the treatment shell 11 and the base 2 needs to be adjusted, first, the handle 333 is rotated in the positive direction, the other end of the lever structure 31 is subjected to the force of the sleeve 332, and moves towards the support point structure 32, under the action of the support point structure 32, one end of the lever structure 31 moves away from the support point structure 32, and since one end of the lever structure 31 is connected with the treatment shell 11, the movement of one end of the lever structure 31 drives the end of the treatment shell 11 close to the ocular lens 1132 to move away from the base 2. When the handle 333 is rotated in the reverse direction, the force acting on the other end of the lever structure 31 is removed, the other end of the lever structure 31 moves away from the support point structure 32, one end of the lever structure 31 moves towards the support point structure 32, and drives the end of the treatment shell 11 close to the ocular lens 1132 to move towards the base 2. Thus, the angle between the treatment shell 11 and the base 2 can be adjusted.

[0073] Please refer to Figures 9-11 The utility model further comprises a second embodiment, and the difference between the second embodiment and the first embodiment is that the lever structure 31 and the support point structure 32 are improved, and the improvement is that:

[0074] In the embodiment, the upper surface of the fulcrum structure 32 is provided with a first recess 322, and the recess depth of the first recess 322 relative to the upper surface of the fulcrum structure 32 is recorded as a second depth. Correspondingly, the lower surface of the lever structure 31 is provided with a second protrusion 312, and the protrusion height of the second protrusion 312 relative to the lower surface of the lever structure 31 is recorded as a second height, which is greater than or equal to the second depth. The second protrusion 312 moves back and forth on the first recess 322.

[0075] Other technical features and technical effects are consistent with the first embodiment, which will not be repeated here.

[0076] Please refer to Figures 12-14 The utility model still includes third embodiment, the difference between third embodiment and first embodiment lies in that the lever structure 31 and fulcrum structure 32 are improved, specifically:

[0077] In the embodiment, the upper surface of the fulcrum structure 32 is provided with at least one first tooth 323, and the height of the first tooth 323 relative to the upper surface of the fulcrum structure 32 is recorded as a third height. Correspondingly, the lower surface of the lever structure 31 is provided with at least two second teeth 313, and the first tooth 323 is engaged with the second tooth 313. The height of the second tooth 313 relative to the lower surface of the lever structure 31 is recorded as a fourth height, which can be less than or equal to the third height, determined by the actual production condition.

[0078] When the second end of the lever structure 31 is pressed down, the first tooth 323 is clamped between the two adjacent second teeth 313. The advantage of this structure is that when the user adjusts the angle of the treatment part 1 and the base 2 to the appropriate vertical, the first tooth 323 and the second tooth 313 can be clamped with each other, so as to fix the angle of the treatment part 1 and the base 2.

[0079] Other technical features and technical effects are consistent with the first embodiment, which will not be repeated here.
