[0025] In an embodiment, the multistage telescopic link 1 is composed of a plurality of first sleeves that are telescopically movable and mutually sleeved, and a rubber ring is arranged between adjacent two first sleeves to increase the moving resistance of the first sleeves.

[0026] In this way, by arranging the rubber ring to increase the telescopic resistance of the first sleeves, the plurality of first sleeves can automatically remain at the adjusted position without being affected by a large external force after being pulled to be elongated or contracted, so that the adjustment process can be further simplified without affecting the telescopic use of the multistage telescopic link 1.

[0033] In this way, when the tension spring 332 is in a natural state, the adjusting disc 331 cannot rotate due to the limitation of the second protrusions on the first protrusions, and the observation mirror 2 can maintain the angle unchanged under the cooperation of the synchronous telescopic assembly 31 and the transmission assembly 32. When the angle of the observation mirror 2 needs to be adjusted, an operator holds the telescopic rod 1 with one hand and pulls down the adjusting disc 331 with the other hand, so that the second protrusions are not located in the rotating area of the first protrusions, and then rotates the adjusting disc 331, thereby driving the synchronous telescopic assembly 31 inserted into the adjusting disc 331 to rotate, and further driving the observation mirror 2 to adjust the angle under the transmission of the transmission assembly 32. When the angle of the observation mirror 2 is adjusted, the operator only needs to release the adjusting disc 331, so that the adjusting disc 331 moves upward under the pulling of the tension spring 332 to reset, thereby maintaining the rotation limitation of the angle of the observation mirror 2.
