DETAILED DESCRIPTION

[0024] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-6 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0025] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0026] Embodiment 1, a cut-proof rolling paper cutter, comprising a paper cutter body 1 and a blade 2, characterized in that:

[0027] The paper cutter body 1 is provided with a first auxiliary plate 3 and a second auxiliary plate 4, and the first auxiliary plate 3 and the second auxiliary plate 4 are slidably connected with a first sliding plate 5 and a second sliding plate 6;

[0028] The first auxiliary plate 3 is provided with a plurality of positioning holes 7 at intervals, the first sliding plate 5 is slidably connected with two groups of adjustment plates 8, a return spring 9 is provided between the two groups of adjustment plates 8 and the first sliding plate 5, and the two groups of adjustment plates 8 are provided with positioning posts 10 corresponding to the positioning holes 7;

[0029] The first auxiliary plate 3 is provided with a nut 11, and the second auxiliary plate 4 is provided with a stud 12 matched with the nut 11;

[0030] The blade 2 is provided with a bearing 13, and the inner ring of the bearing 13 is interference fit with the stud 12;

[0031] The paper cutter body 1 is provided with a blade 2 clamp corresponding to the blade 2 .

[0032] When installing the blade 2, the blade 2 is placed in the middle of the paper cutter body 1 through the gap of the blade 2 and located between the first sliding plate 5 and the second sliding plate 6. The stud 12 passes through the second sliding plate 6 and the inner ring of the bearing 13 of the blade 2. Finally, the stud 12 is matched with the nut 11 provided on the first sliding plate 5. After the matching is completed, the blade 2 can rotate along the stud 12.

[0033] After the blade 2 is installed, the adjustment plate 8 can be moved to overcome the movement of the auxiliary spring, and the positioning column 10 can be disengaged from the positioning hole 7. At this time, the first sliding plate 5 and the second sliding plate 6 can be moved along the first auxiliary plate 3 and the second auxiliary plate 4 to adjust the height of the blade 2 in the paper cutter body 1;

[0034] When not in use, the blade 2 is inserted deep into the paper cutter body 1, which is highly safe and avoids accidental injury by the blade 2. When in use, the height of the blade 2 extending out of the paper cutter body 1 can be controlled, and the blade 2 can be adjusted according to actual application conditions for easy adjustment.

[0035] Embodiment 2, based on embodiment 1, the paper cutter body 1 is detachably connected with a front baffle 15 and a rear baffle 16 corresponding to the gap of the blade 2, and the front baffle 15 and the rear baffle 16 are both provided with a baffle groove 17 corresponding to the blade 2.

[0036] When descending, the front baffle 15 and the rear baffle 16 can play a good guiding role to avoid cutting errors, while also ensuring that only a small part of the blade 2 is exposed. If an operation error is made, the front baffle 15 will hit the palm first, thereby preventing cuts. In addition, in order to ensure that the blade 2 can rotate normally, a baffle groove 17 is added between the front baffle 15 and the rear baffle 16 to leave space for the blade 2 to roll.

[0037] Embodiment 3, on the basis of embodiment 2, the paper cutter body 1 includes a handle, and the handle is provided with an anti-slip pad; the front baffle 15 and the rear baffle 16 are connected to the paper cutter body 1 by screws or welded by hot melt adhesive; the front baffle 15 and the rear baffle 16 and the paper cutter body 1 are all made of transparent acrylic material.

[0038] When in use, the front baffle 15, the rear baffle 16 and the paper cutter body 1 are all made of transparent acrylic material, so as to avoid the problem of the protective device blocking the sight;

[0039] The front baffle 15 and the rear baffle 16 are connected to the paper cutter body 1 by screws or by hot melt adhesive, thereby ensuring the stability of the connection between the front baffle 15 and the rear baffle 16 and the paper cutter body 1 .

[0040] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
