[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with an L-shaped support plate on a U-shaped support plate. When the fixing rod 2 is separated and moved across the central axis of the device again, the extrusion airbag will be squeezed by the collision ball. When the collision ball is squeezed, the air inside will be quickly sprayed to the slit lamp through the air jet port, so that the dust falling inside the slit lamp can be cleaned conveniently and timely, and the situation that the light is not suitable for use or focusing due to dust accumulation can be reduced.

[0015] 2. The utility model provides an elastic belt on the adjusting ring. When the elastic belt is rotated, it will drive multiple adjusting rings to start rotating at the same time. When the adjusting ring is rotated, it will drive the rotating column so that the connecting rod drives the rotating ring to move in a circle in the sliding groove. When the slit lamp is adjusted and does not need to be moved but the examination table needs to be readjusted, the elastic belt can be pulled to separate it from the adjusting ring. Then the adjusting ring on the fixed rod can be rotated to move the examination table alone. When the examination table moves alone, the connecting arc plate will also drive the fixed rod 2 to start rotating the rotating ring in situ. This makes it convenient to adjust the angle alone and move coaxially, making it convenient to use the equipment and not only to use the light but also to check the patient's eyes.

[0016] 3. The utility model is provided with a slit lamp on a fixed rod 2. When the staff uses the equipment, the slit lamp is directed toward the patient to be examined, and then the slit lamp is turned on to produce vertical light. The slit lamp can quickly focus the patient's pupil for convenient eye examination by the staff. The user can aim at the observation barrel and observe the focused pupil through the observation mirror. If adjustment is required, the internal focuser can be adjusted to the required degree by rotating the multiple adjustment rings 2. If different observation mirrors need to be replaced, the lifting block can be moved to make the annular plate squeeze the elastic arc plate into the installation groove. Multiple observation mirrors can be taken out and replaced with different observation mirrors for convenient adjustment of the observation intensity. The patient's eyeball can be examined during the lighting process. At the same time, the pupil can be quickly focused for convenient examination. Different focusers required for adjustment can be conveniently replaced and adjusted, thereby enhancing the applicability and portability of the equipment.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
