[0031] The adjusting mechanism 5 includes a transmission unit and a limiting unit;

[0032] The transmission unit is used for adjusting the gap between the separating rods 2;

[0033] The limiting unit is used for limiting the transmission unit after movement;

[0034] The transmission unit includes a guiding groove 501, a rotating block 502, and a pulling block 503;

[0035] The guiding groove 501 is opened at the top end of the supporting seat 4, and the guiding groove 501 is used for guiding the movement of the guiding rod 3;

[0036] The rotating block 502 is rotatably connected to the protruding part at the top end of the guiding rod 3, and the rotating block 502 is used for driving the pulling block 503 to rotate;

[0037] The pulling block 503 is rotatably connected to both ends of the rotating block 502, and the pulling block 503 is used for applying a thrust or a pulling force to the guiding rod 3;

[0038] The limiting unit includes a limiting groove 504, a movable rod 505, a limiting block 506, a positioning rod 507, and a spring 508;

[0039] The limiting groove 504 starts on the outer wall of the support base 4, and the limiting groove 504 is used to limit the movement of the limiting block 506;

[0040] The movable rod 505 is axially slidably installed in the shaft cavity of the rotating block 502 and extends to the outside of the rotating block 502. The movable rod 505 is used to drive the limiting block 506 to move and the rotating block 502 to rotate;

[0041] The limiting block 506 is fixed to the outer wall of the movable rod 505 and extends into the inner cavity of the limiting groove 504. The limiting block 506 is used to limit the rotation of the movable rod 505;

[0042] The positioning rod 507 is fixed to one end of the movable rod 505 and extends into the shaft cavity of the rotating block 502. The positioning rod 507 is used to guide the movement of the movable rod 505;

[0043] The two ends of the spring 508 are respectively clamped on the inner cavity of the shaft of the rotating block 502 and the outer wall of the positioning rod 507. The spring 508 is used to always provide an elastic force in one direction for the positioning rod 507;

[0044] The number of the distinguishing rods 2 is set to two, and the two distinguishing rods 2 are symmetrically and obliquely distributed downward.

[0045] In this embodiment: When it is necessary to adjust the gap between the two distinguishing rods 2, an outward pulling force can be applied to the movable rod 505. The stressed movable rod 505 synchronously drives the limiting block 506 to move, so that the limiting block 506 moves out of the inner cavity of the limiting groove 504 and no longer limits the rotation of the movable rod 505. At this time, the movable rod 505 can be rotated. The rotated movable rod 505 will synchronously drive the positioning rod 507 to rotate, so that the convex block at the top of the positioning rod 507 transmits the rotational force to the rotating block 502, thereby synchronously driving the rotating block 502 to rotate.

The number of the limiting grooves 504 is set to be multiple, and the multiple limiting grooves 504 are circumferentially distributed on the support base 4 with the midpoint of the movable rod 505 as the axis. A chute for the vertical movement of the outer wall of the pulling block 503 is formed in the inner cavity of the guiding rod 3. The midpoint of the movement track in the inner cavity of the guiding groove 501 is the same as the midpoint of the rotation track of the distinguishing rod 2.

[0047] In this embodiment: through this structure, during the process that the movable rod 505 moves outward under force, the positioning rod 507 at the end of the movable rod 505 will also move along with the movement of the movable rod 505, thereby applying an extrusion force to the spring 508 until the gap of the distinguishing rod 2 is adjusted to the required distance. At this time, when the movable rod 505 is not subjected to an external pulling force, the positioning rod 507 will drive the movable rod 505 and the limiting block 506 to move under the action of the spring 508, and the limiting block 506 entering the inner cavity of the limiting groove 504 will limit the rotation of the movable rod 505 again.
