The structure and function of the solution of the present application will now be described in detail with reference to fig. 1 to 6.

The utility model provides a paper storehouse sliding adjustment spare combines fig. 1 to 4, and it includes and contains a sliding block 2 and a rotating piece 1, and sliding block 2 contains a stop gear 3 that has a dysmorphism rotation groove 32 and one connects in stop gear 3's arc sliding plate 5, and arc sliding plate 5 has a first fluting 51 that leads to dysmorphism rotation groove 32. The first slot 51 extends in the axial direction of the arc-shaped sliding plate 5. The rotating member 1 includes a modified rotating shaft 11 fitted in the modified rotating groove 32, and a crank 12 having one end connected to the modified rotating shaft 11. By pulling the other end of the crank 12 away from the shaped rotation shaft 11, the rotation member 1 can be rotated around the shaped rotation groove 32 relative to the slide block 2. The shaped rotating groove 32 brings the first open groove 51 to elastically expand or elastically contract during the rotation of the rotating member 1.

Referring to fig. 4, the irregular-shaped rotating shaft 11 includes a pressing portion 111 in a circumferential direction and a hollow portion 112 having a smaller size than the pressing portion 111 in a radial direction. The inner peripheral wall of the irregular rotation groove 32 includes a receiving portion 321 that can receive the pressing portion 111, a holding portion 322 that is smaller in radial dimension than the receiving portion 321 and is adapted to the pressing portion 111, and a pressure receiving portion 323 that is connected to the receiving portion 321 and the holding portion 322. The first slot 51 can keep elastically opened when the pressing portion 111 abuts against the holding portion 322. In this embodiment, when the rotating member 1 rotates in the first direction, the end of the pressing portion 111 along the first direction is connected to the hollow portion 112 through an arc segment 113, the arc segment 113 protrudes outward in the radial direction, and the arc segment 113 is smoothly connected to the pressing portion 111. The other end of the pressing portion 111 opposite to the first direction is connected to the hollow portion 112 through a straight section. The pressure-receiving portion 323 protrudes radially inward, and the pressure-receiving portion 323 is arc-transitionally connected with the receiving portion 321 and the holding portion 322, respectively. The pressure receiving portion 323 is connected to one end of the receiving portion 321 in the first direction. When the rotating member 1 rotates in the first direction, the arc segment 113 presses the pressure-bearing portion 323 to drive the first open slot 51 to elastically open towards the left and right sides, the pressing portion 111 moves from the receiving portion 321 to the holding portion 322, and when the pressing portion 111 keeps contact with the holding portion 322, the width of the first open slot 51 opening towards the left and right sides is kept within a certain threshold. Wherein, the first direction is one of clockwise direction or anticlockwise direction.

As can be seen from the above, the outer peripheries of the pressing portion 111 and the hollow portion 112 on the special-shaped rotating shaft 11 are of the arc structure, and the inner peripheries of the receiving portion 321, the holding portion 322 and the pressure receiving portion 323 on the special-shaped rotating groove 32 are of the arc structure, so that when the special-shaped rotating shaft 11 props up the special-shaped rotating groove 32, the special-shaped rotating shaft 11 and the special-shaped rotating groove 32 are in line contact (along the axial direction) and are in arc transition, thereby reducing the resistance of the toggle rotating member to rotate, and when the thrust applied to the special-shaped rotating groove 32 by the special-shaped rotating shaft 11 maintains the width of the first open groove 51 opened along the left and right sides within a certain threshold, the special-shaped rotating shaft 11 and the special-shaped rotating groove 32 can be in surface contact, so that the rotating member rotates even if the external force is.

In the embodiment of the present invention, referring to fig. 1 and 4, the limiting mechanism 3 includes a first blocking plate 31 having a first fastening portion 41, and the crank 12 has a second fastening portion 13. The first fastening portion 41 and the second fastening portion 13 are disposed opposite to each other, the first fastening portion 41 is a protrusion extending toward the second fastening portion 13 along the axial direction, and the second fastening portion 13 is a fastening groove capable of being received and adapted to the first fastening portion 41. Specifically, the first fastening portion 41 is a bump with a cone structure. The rotation member 1 can stop rotating when the second fastening part 13 is fastened to the first fastening part 41, so that the first open groove 51 is kept in an elastically opened state, and the width of the first open groove 51 opened along the left and right sides is kept within a certain threshold. Further, when the first fastening part 41 is fastened to the second fastening part 13, the rotating member 1, the sliding block 2 or the paper compartment sliding adjusting member itself will not rotate relative to the rotating member 1 when an external force is applied to the rotating member 1, the sliding block 2 or the paper compartment sliding adjusting member itself.

In the embodiment of the present invention, referring to fig. 2, the first baffle 31 is configured with a spring wall 4, the first fastening portion 41 is configured on the spring wall 4, and the spring wall 4 generates elastic deformation under the pushing force of the second fastening portion 13. It is understood that, in other embodiments, when the second fastening part 13 is a bump, the spring wall 4 is elastically deformed by the pushing force of the second fastening part 13. In this embodiment, the spring wall 4 preferably extends along the moving track of the second fastening portion 13, and the first fastening portion 41 is disposed at the end of the moving track on the spring wall 4.
