The lower end of the screw rod 42 passes through the through hole 21 of the fixing plate 2 and simultaneously passes through the through hole 31 of the connecting plate 3 and the positioning nut 43. The screw rod 42 is screwed with the positioning nut 43, and since the positioning nut 43 is locked in the nut hole 22 of the fixing plate 2, that is, the positioning nut 43 does not rotate, the screw rod 42 moves up and down relative to the positioning nut 43 and the fixing plate 2 when rotating.

The limiting component 6 is usually installed on the screw rod 42 and rotates synchronously with the screw rod 42, and comprises an upper limiting part and a lower limiting part which clamp the connecting plate 3 on a certain fixed screw rod section, and the upper limiting part is tightly attached to the upper port of the through hole 31; the lower retainer abuts against the lower end of the through hole 32.

With continued reference to fig. 3, in the present embodiment, the upper portion of the screw 42 is formed with a screw widening portion 71 having a larger diameter, the diameter of the screw widening portion 71 is larger than that of the through hole 31, and in the present embodiment, the upper positioning portion is composed of the screw widening portion 71 and a first washer 72, a lower end surface of the first washer 72 abuts against an upper end opening of the through hole 31, and an upper end surface of the first washer 72 abuts against a lower end surface of the screw widening portion 71.

Through the setting of above-mentioned structure, can ensure the screw rod section in the through-hole 31, not only can be for connecting plate 31 free rotation, this screw rod section is located spacing subassembly 6 all the time moreover, and this screw rod section can not take place relative displacement with spacing subassembly 6 promptly.

The crossed roller guide rail 5 (the crossed roller guide rail 5 is common in the prior art and is not described again here, the utility model discloses a linear type) comprises a female guide rail 51 and a male guide rail which are matched with each other, and the female guide rail 51 is fixedly connected with the assembly plate 1; the sub-guide rail is fixedly connected with the fixed plate 2.

Referring also to fig. 4, in the preferred embodiment, the female guide rail 51 is provided with V-shaped raceways on both left and right sides (not shown in the figure for viewing reasons); the sub-guide rails comprise a left sub-guide rail 52 and a right sub-guide rail 53 which are respectively connected with the fixed plate 2, the right side of the left sub-guide rail 52 is provided with a V-shaped raceway (not shown in the figure due to the view angle), and the V-shaped raceway is matched with the V-shaped raceway on the left side of the main guide rail 51; the right sub-rail 53 is provided on its left side with a V-shaped raceway (not shown for reasons of perspective) which cooperates with a V-shaped raceway on the right side of the female rail 51. In use, the left sub-rail 52 and the right sub-rail 53 are relatively displaceable along the main rail 51, respectively.

In operation, the fixed plate 2 is fixed to other parts of the paper feeder, and the female guide rail 51 is fixedly mounted on the fixed plate 2, i.e. the fixed plate 2 and the female guide rail 51 are always in a relatively stationary state. Since the positioning nut 43 is locked in the nut hole 22 of the fixing plate 2, that is, the positioning nut 43 does not rotate, the screw rod 42 is displaced up and down relative to the positioning nut 43 and the fixing plate 2 when rotating. Meanwhile, the limiting component 6 can ensure that the connecting plate 3 can move up and down (but does not rotate) along with the screw rod 42, and because the assembly plate 1 is fixed with the connecting plate 3, relevant parts (including the paper pressing wheel 11) installed on the assembly plate 1 and the left sub-guide rail 52 and the right sub-guide rail 53 fixed with the assembly plate 1 can move up and down along with the screw rod 42, so that relative displacement can occur. That is, by rotating the fine adjustment handle 41, the screw rod 42, the fine adjustment handle 41, the connecting plate 3, the left sub-rail 52, the right sub-rail 53, the mounting plate 1, and the relevant parts (including the paper pressing wheel 11) mounted on the mounting plate 1 are moved up or down as a whole with respect to the fixed plate 2 and the female rail 51, thereby adjusting the distance between the paper pressing wheel 11 and the paper feeding roller (not shown).

The present invention has been described in detail with reference to the embodiments, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention.
