Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, the present invention discloses a straight rod rotating mirror, which comprises an endoscope body 1, an outer mirror tube 2 and a rotating structure 3;

the outer surface of the endoscope body 1 is fixedly connected with a rotating structure 3, and one end of the rotating structure 3 is fixedly connected with an outer endoscope tube 2;

the rotating structure 3 comprises a fixed end 31, one side of the outer surface of the fixed end 31 is fixedly connected to the outer surface of the endoscope body 1, the other side of the outer surface of the fixed end 31 is fixedly connected with a connecting pipe 32, the outer surface of the connecting pipe 32 is rotatably connected with a rotating pipe 33, the inner side wall of the rotating pipe 33 is fixedly connected with a mounting pipe 34, and one end of the mounting pipe 34 is fixedly connected with the outer endoscope pipe 2; the outer surface of the connecting pipe 32 is fixedly connected with a limiting block 35, one end of the rotating pipe 33 close to the connecting pipe 32 is fixedly connected with a convex block 36, and the outer surface of the convex block 36 is movably connected with the limiting block 35;

the outer surface of the connecting pipe 32 is fixedly connected with a limiting block 35, when the rotating pipe 33 rotates in a single direction, a bump 36 on the rotating pipe 33 meets the limiting block 35 on the connecting pipe 32, the limiting block 35 blocks the bump 36 to continue rotating in the single direction, and at the meeting position of the limiting block 35 and the bump 36, because the limiting block 35 and the bump 36 both have certain thickness, the angle of the single direction rotation is smaller than 360 degrees, namely, the phenomenon that when the rotating pipe rotates in the single direction all the time, the inner connecting line is knotted or twisted off is avoided;

the outer surface of the mounting tube 34 is fixedly connected with a rotating wheel 38 through a positioning bolt; the outer surface of the connecting pipe 32 is in threaded connection with a protective sleeve 37, and the rotary pipe 33 is rotatably connected inside the protective sleeve 37; a through hole is arranged at the center of the fixed end 31;
