When the limit switch lever 10 moves to the limit switch 11 and contacts the limit switch 11, the limit switch 11 generates a switch signal, which indicates that the limit switch 11 lever 10 has moved to the limit position.
Referring to fig. 5, the condenser lens slider 5 is fixed on the guide rod base 4 through two linear guide rods 18, the two linear guide rods 18 are respectively inserted into two ends of the condenser lens slider 5, and the linear guide rods 18 are fixed on the guide rod base 4 through linear bearings 17 sleeved at two ends, so that the condenser lens slider 5 is connected with the guide rod base 4.
And an adjusting screw 19 is inserted into one end of the guide rod seat 4, the adjusting screw 19 sequentially penetrates through the guide rod seat 4 and the condenser lens sliding block 5, the adjusting screw 19 is rotated, and the distance between the condenser lens sliding block 5 and the guide rod seat 4 is adjusted, namely the adjusting screw is used for adjusting the limit stroke of the condenser lens sliding block 5 and determining the focal length of the small light spot.
Referring to fig. 4, the third assembly body includes a stepping motor 6, and an output shaft of the stepping motor 6 is connected to a ball screw 16; the ball screw 16 is sleeved with a nut 14, the nut 14 is fixed in the nut seat 13, and two ends of the nut seat 13 are respectively sleeved with a spring 15.
The nut 14 is connected with the ball screw 16 through a screw thread, when the stepping motor 6 operates, the ball screw 16 rotates, the nut 14 moves (linearly moves) along the ball screw 16 along with the rotation of the ball screw 16, the nut 14 linearly moves, and the nut holder 13 is driven to move along the ball screw 16.
Referring to fig. 6 and 8, the connection between the first assembly and the second assembly.

In the moving process, because the springs 15 are sleeved at the two ends of the nut seat 13, when the nut seat 13 drives the limit switch pull rod 10 to move to the limit position, the total displacement of the nut seat 13 is 10mm, wherein 9mm is the compression amount of the springs 15, namely, the limit switch 11 pull rod 10 drives the condenser lens to move only 1 mm.
In the moving process, under the power action of the stepping motor 6, the condenser lens slide block 5 reciprocates along the linear guide rod 18, and the adjustment of the change of the size of the light spot is realized. When the nut seat 13 drives the pull rod 10 of the limit switch 11 to move to the limit position, the pull rod 10 of the limit switch contacts with the limit switch 11, the limit switch 11 sends a signal (an alarm signal) to an external computer, and the external computer controls the step motor 6 to stop working (or manually controls the step motor 6 to stop working).
Meanwhile, due to the compression buffering of the spring 15 and the alarm signal of the limit switch 11, the collision between the condenser lens mounting seat 7 (which is light in weight, small in thickness and easy to damage) and the guide rod seat 4 can be effectively avoided, and the condenser lens mounting seat 7 is prevented from being damaged.
The utility model can adjust the focal length of the condensing lens by sliding the guide rod seat 4, and lock the condensing lens by rotating the handle bolt 8, thereby determining the focal length of the large facula; rotating the adjusting screw 19, adjusting the limit stroke of the condenser lens slide block 5, and determining the focal length of the small light spot; under the power action of the stepping motor 6, the condenser lens slide block 5 reciprocates along the linear guide rod 18 to realize the change of large and small light spots.
