The whole working principle is that when the rotation range of the first sheath 1 and the second sheath 2 needs to be narrowed, the shift lever 316 is rotated, the shift lever 316 rotates to drive the clamping lever 310 to rotate, the clamping lever 310 rotates to drive the clamping block 314 to slide out of the inner wall of the arc-shaped groove 315, then the positioning plate 308 is rotated, the positioning plate 308 rotates to drive the inserting rod 309 to rotate, the inserting rod 309 rotates to drive the clamping lever 310 to slide along the inclined plane of the protruding block 312, at the moment, the inclined plane of the protruding block 312 can press the clamping lever 310 to slide in the direction far from the protruding block 312, the clamping lever 310 continuously rotates to be separated from the protruding block 312, because the spring 313 is always in a contracted state, the inserting rod 309 slides in the direction close to the protruding block 312 by the pulling force of the spring 313, the inserting rod 309 drives the clamping lever 310 to abut against the inner wall of the mounting groove 311 again, at the moment, the protruding block 312 reaches the position limiting function of the clamping lever 310 to limit the position of the positioning plate 308, when the second sheath 2 rotates, the supporting plate 304 drives the rotating rod 303 to rotate along the inner wall of the circular tube 302 by means of the rotation of the second sheath 2, the rotation of the rotating rod 303 drives the circular plate 305, the rotation of the circular plate 305 drives the positioning plate 308 to rotate, the rotation of the positioning plate 308 contacts with the positioning rod 307, the positioning plate 308 and the sliding groove 306 reach the effect of limiting the rotation range of the positioning rod 307, so that the first sheath 1 and the second sheath 2 can rotate within a certain range, when the rotation range of the first sheath 1 and the second sheath 2 needs to be enlarged, the inserting rod 309 is pulled in a direction away from the circular plate 305, the inserting rod 309 slides to stretch the spring 313, the spring 313 is in a stretched state, the inserting rod 309 slides to drive the clamping rod 310 to synchronously slide, the clamping rod 310 is separated from the inner wall of the mounting groove 311, the positioning plate 308 rotates in the opposite direction, the clamping rod 310 rotates, after the clamping rod 310 is adjusted to a proper position, the inserting rod 309 is loosened, at this time, the inserting rod 309 drives the clamping rod 310 to abut against the surface of the protruding block 312 again by means of the tensile force of the spring 313, then the shifting rod 316 is rotated, the shifting rod 316 is rotated to drive the clamping rod 310 to rotate, the clamping rod 310 is rotated to drive the clamping block 314 to slide into the inner wall of the arc-shaped groove 315 again, at this time, the arc-shaped groove 315 can limit the position of the clamping block 314 and further limit the position of the clamping rod 310, and the situation that a patient touches the inserting rod 309 by mistake to the greatest extent, and the rotation range of the positioning rod 307 is enlarged is prevented.
When the elbow rest 44 is needed, the driving plate 55 is rotated firstly, the driving plate 55 rotates to drive the nut 52 to rotate, the nut 52 moves in the direction away from the rectangular frame 54 by virtue of threads when rotating, the nut 52 moves to be separated from contact with the rectangular frame 54, then the rectangular plate 42 can slide, the rectangular plate 42 slides to drive the threaded column 51 to slide along the rectangular frame 54, the rectangular plate 42 slides to drive the screw 43 to move, the push plate 45 moves to drive the elbow rest 44 by virtue of the movement of the screw 43, the driving plate 55 rotates to drive the nut 52 to rotate in the opposite direction after the elbow rest 44 moves to a proper position, the nut 52 moves to the direction close to the rectangular frame 54 by virtue of threads when rotating, after the nut 52 abuts against the surface of the rectangular frame 54, the nut 52 reaches the effect of limiting the position of the threaded column 51 and further limiting the position of the rectangular plate 42, then the rotating plate 49 rotates to drive the screw 43 to rotate, the rotating plate 49 achieves the effect of conveniently rotating the screw 43, the groove reaches the effect of increasing the surface friction of the rotating plate 49, the screw 43 moves upwards by virtue of the screw 45, the push plate 45 moves to drive the push plate 45 to move upwards, the directional plate 46 moves to drive the push plate 46 to move along the round push plate 45, the round push plate 45 moves to limit the round push plate 45 to move along the round push plate 45, and the round push plate 45 moves more conveniently, the round plate 45 moves along the round push plate 45 moves the round push plate 45, thereby the round plate 45 moves more so that reaches the effect of the sliding plate 45 is more convenient to slide path, and the round plate 46 moves is more convenient to move the round plate 45.
