[0021] Please see Figures 1-4A telescope eyepiece structure includes a mounting cylinder 1, a guide sleeve 2 fitted on the surface of the mounting cylinder 1, a connecting shell 3 welded to the top of the mounting cylinder 1, a connecting block 5 snapped into the inner cavity of the connecting shell 3, a pushing sleeve 6 welded to the top of the connecting block 5, a driving sleeve 7 rotatably connected to the top of the guide sleeve 2, a positioning component 16 provided on the top of the connecting shell 3, a convex lens 13 mounted on the top of the positioning component 16, and a positioning sleeve 15 fitted on the top of the positioning component 16.

[0022] Please see Figure 1 and Figure 4 The positioning component 16 includes a connecting ring 11, the surface of which is rotatably connected to the drive sleeve 7. A first elastic pad 12 is bonded to the top of the connecting ring 11, the top of which contacts the convex lens 13. A second elastic pad 14 is covered on the top of the convex lens 13. The surfaces of the first elastic pad 12 and the second elastic pad 14 are slidably connected to the positioning sleeve 15. By setting the positioning sleeve 15, the first elastic pad 12, the convex lens 13 and the second elastic pad 14 can be easily positioned, and the first elastic pad 12, the convex lens 13 and the second elastic pad 14 can be effectively prevented from falling off.

[0023] Please see Figure 1 and Figure 4 The surface of the connecting ring 11 is threadedly connected to the positioning sleeve 15. The first elastic pad 12 and the second elastic pad 14 are both made of elastic rubber. By setting the first elastic pad 12 and the second elastic pad 14, the convex lens 13 can be easily protected and can be effectively prevented from being damaged.

[0024] Please see Figure 1 and Figure 4 The bottom of the connecting ring 11 is connected to the guide rod 10 by bolts, and the top of the connecting shell 3 is welded to the guide shell 9. By setting the guide rod 10 and the guide shell 9, the mounting cylinder 1 and the connecting shell 3 can be guided and positioned, and the mounting cylinder 1 and the connecting shell 3 can be moved stably.

[0025] Please see Figure 1 and Figure 4 A baffle is welded to the bottom of the guide rod 10. By setting the baffle, it can play a positioning role and effectively prevent the guide rod 10 from detaching from the guide shell 9. The bottom of the baffle extends through the inner cavity of the guide shell 9 and is slidably connected to the guide shell 9.

[0026] Please see Figure 2 and Figure 3 The surface of the connecting shell 3 is welded with a slider 4, and the inner cavity of the guide sleeve 2 is provided with a groove 8.
