When the condenser adjustment limit pin 9 is installed in the waist hole on the lamp holder clamping sleeve 8, when in use, the finger turns the knob rubber sleeve 10, which will cause the condenser seat 6 to rotate. At this time, the condenser adjustment limit pin 9 on the condenser seat 6 passes through the waist hole on the lamp holder clamping sleeve 8, which will cause the lamp holder clamping sleeve 8 to be rotated, and then the ribs on the lamp holder clamping sleeve 8 drive the negative electrode lamp holder 15 to rotate, thereby realizing the function of rotating the strip light and the function of focusing the strip light; similarly, when in use, the finger moves the 10-knob rubber sleeve up and down, and the strip light focusing function can be realized by moving the condenser 5 up and down.

[0048] The utility model provides a novel retinoscope, which separates the function of the conductive mechanism of the bulb from the dimming knob by adjusting the position of the condenser 5. The knob rubber cover 10 has a good hand feel when used. When the finger leaves the knob, the knob can stay in place, which is convenient to use.

[0049] At the same time, this structure can optimize the conductive mechanism, so that the traditional dimming knob does not need to be made of metal materials, so the shape of the knob is also improved.
