[0036] Preferably, as shown in Figure 1 the hinged mechanism 3 comprises a first hinged piece 31 and a second hinged piece 32, the top end of the column 9 is hinged with one end of the force pressing rod 2 through the first hinged piece 31, the second hinged piece 32 is arranged on the side wall of the force pressing rod 2, and the force pressing rod 2 is hinged with the top end of the pressing rod 4 through the second hinged piece 32.

[0037] The beneficial effects of the above preferred scheme are: the first hinged piece is beneficial to make the force pressing rod rotate around the top end of the column, and the second hinged piece cooperates with the adjusting mechanism and the supporting mechanism, which is beneficial to make the pressing rod keep vertical state during the rotation of the force pressing rod, so that the blade receives a vertical force.

[0038] Preferably, as shown in Figure 1As shown, the support mechanism 7 comprises a first support 71 and a second support 72, the first support 71 is a plate structure, and the second support 72 is a hollow cylindrical structure arranged horizontally below the first support 71.

[0039] The above-mentioned preferred embodiment has the beneficial effect that the support mechanism is conducive to ensuring the stability of the adjustment mechanism when adjusting the angle and when being pressed down, thereby making the force applied to the blade constant, improving the cutting efficiency and effect.

[0040] Preferably, as shown in the drawings, Figure 1 As shown, the protection mechanism 8 comprises a protection shell 81 and a first return spring 82, the protection shell 81 is a shell structure arranged at the top end of the first support 71, and the top end and the bottom end are both provided with openings, and the first return spring 82 is arranged in the middle of the protection shell 81.

[0041] The above-mentioned preferred embodiment has the beneficial effect that the protection shell is conducive to providing buffering when the adjustment mechanism is lowered, avoiding damage to the device when pressing the force pressing rod with great force, and the first return spring is conducive to rebounding the adjustment mechanism to the initial state after cutting is completed by using the spring rebounding force.

[0042] Preferably, as shown in the drawings, Figure 1 As shown, the adjustment mechanism 6 comprises a size conversion knob 61, a connecting rod 62, a pressing plate 63, and a spring baffle 64, the top end and the bottom end of the connecting rod 62 are one-to-one connected with the size conversion knob 61 and the pressing plate 63 vertically, the size of the spring baffle 64 is adapted to the top end opening of the protection shell 81, the first return spring 82 is arranged around the connecting rod 62, and the two ends are one-to-one abutted with the first support 71 and the spring baffle 64.

[0043] The above-mentioned preferred embodiment has the beneficial effect that by rotating the size conversion knob, the pressing plate can be adjusted to different angles and press different blades, thereby cutting products of different specifications.

[0044] Preferably, as shown in the drawings, Figure 1 As shown, the top end of the size conversion knob 61 is provided with a groove, and the pressing rod 4 is rotatably installed in the groove at the top end of the size conversion knob 61.

[0045] The above-mentioned preferred embodiment has the beneficial effect that the pressing rod is rotatably installed in the groove at the top end of the size conversion knob, which is conducive to avoiding affecting the pressing rod when rotating the size conversion knob.

[0046] Preferably, as shown in the drawings, Figures 1 to 5As shown, the connecting rod 62 is vertically arranged and passes through the top sidewall of the first support member 71 and the second support member 72. The pressing plate 63 is a cross-shaped plate structure arranged inside the second support member 72.

[0047] The advantages of adopting the above preferred solution are: the connecting rod is set vertically and connected to the pressure plate perpendicularly, which helps to make the pressure plate horizontal, apply a constant force to the blade, and improve the cutting effect.

[0048] Preferred, such as Figures 1 to 5 As shown, the blade 5 can be vertically displaced through the bottom sidewall of the second support member 72. The blade 5 includes: multiple first force-bearing protrusions 51, multiple first blades 52, multiple second force-bearing protrusions 53, and multiple second blades 54. The multiple first force-bearing protrusions 51 are respectively disposed at the top of the multiple first blades 52, and the multiple second force-bearing protrusions 53 are respectively disposed at the top of the multiple second blades 54.

The multiple first blades 52 are wound around each other in stages, and the multiple second blades 54 are wound around each other in stages. The first force-bearing protrusions 51 on the multiple first blades 52 are staggered, and the second force-bearing protrusions 53 on the multiple second blades 54 are staggered.

[0049] It should be noted that: "misaligned setting" means that the first force-bearing protrusion 51 on each first blade 52 has a certain angle in the circumferential direction, and the second force-bearing protrusion 53 on each second blade 54 has a certain angle in the circumferential direction; "gradual winding setting" means that the multiple first blades 52 and the multiple second blades 54 are arranged at a certain interval in a graded manner, and the larger first blades 52 or second blades 54 surround the smaller first blades 52 or second blades 54.

[0050] The advantages of adopting the above-mentioned preferred solution are as follows: the force-bearing protrusion at the tip of the blade abuts against the pressure plate, which helps to transfer the force applied by the pressure plate to the blade, causing the blade to move downward, thereby cutting the artificial skin into a shape that is the same as the blade's outline. The multiple first blades and multiple second blades arranged in stages are conducive to cutting artificial skin products of different specifications in conjunction with the pressure plate. The staggered force-bearing protrusions are also conducive to adjusting the pressure plate above the force-bearing protrusions in conjunction with the size adjustment knob, and applying a downward force to achieve downward cutting of blades of different specifications, thereby obtaining artificial skin products of different specifications.

[0051] Preferred, such as Figure 6As shown, the blade reset mechanism 11 comprises a force receiving sheet 111, a second reset spring 112 and a plurality of limiting convex points 113, the force receiving sheet 111 is a plate structure fixedly installed at the top end of the first force receiving convex block 51 or the second force receiving convex block 53, the second reset spring 112 is in one-to-one correspondence with the bottom end of the force receiving sheet 111 and the inner wall of the bottom end of the second support 72 at both ends, and a plurality of limiting convex points 113 are arranged on the bottom end side wall of the first blade 52 or the second blade 54 and below the second support 72.

[0052] The beneficial effect of the above preferred scheme is that after the blade moves downward under the force to cut the artificial leather, the blade is pushed upward back under the action of the second reset spring, and the limiting convex points are beneficial to avoid the blade being pushed out of the second support by excessive force.

[0053] Preferably, as shown in the drawings, the first blade 52 and the second blade 54 are connected by a connecting rod 6, and the connecting rod 6 is arranged on the bottom end of the first blade 52 or the second blade 54. Figures 3 to 5 As shown, it further comprises an artificial leather 10, the artificial leather 10 is arranged between the base 1 and the bottom end plate structure of the second support 72, and the blade 5 is arranged above the artificial leather 10.

[0054] The beneficial effect of the above preferred scheme is that the artificial leather is arranged below the blade, which is beneficial to move downward after the blade is subjected to downward force, so as to cut the artificial leather into a finished product corresponding to the contour of the blade.

[0055] The working process of the present application will be described below through an embodiment:

[0056] As shown in the drawings, in the preferred embodiment of the present application, the finished product to be cut is a nose mask, and the nose mask is divided into three sizes of large, medium and small, and two sizes of nostrils are arranged, that is, three first blades 52 and two second blades 54 are arranged. Figures 1 to 6 The blade 5 for cutting large and medium nose masks and the blade 5 for cutting large nostrils are provided with a plurality of blade reset mechanisms 11, and the blade 5 for cutting small nose masks and the blade 5 for cutting small nostrils are connected by two blade reset mechanisms 11, that is, the blade 5 for cutting small nose masks and the blade 5 for cutting small nostrils are reset and popped up at the same time.

[0057] When cutting a small size nose mask, first rotate the size conversion knob 61 to rotate the pressing plate 63 above the first force convex block 51 at the top end of the first blade 52 and above the second force convex block 53 at the top end of the second blade 54 (it should be noted that at this time, the selection of the second blade 54 only needs to select the second blade 54 corresponding to the required nostril size according to actual needs); then press the force pressing rod 2, so that the force pressing rod 2 rotates clockwise around the first hinge 31, thereby pushing the downward pressing rod 4 to vertically displace downward, and the downward pressing rod 4 pushes the adjusting mechanism 6 to displace downward, so that the pressing plate 63 displaces downward to contact the first force convex block 51 at the top end of the first blade 52 and the second force convex block 53 at the top end of the second blade 54. With the continuous force on the force pressing rod 2, the pressing plate 63 gradually presses the first blade 52 and the second blade 54 of the innermost circle, and cuts out a small size nose mask and a required size of the nostril. In this process, the first return spring 82 will be continuously compressed and stored due to the continuous downward displacement of the spring baffle 64, and the second return spring 112 will be continuously compressed and stored due to the continuous downward displacement of the force receiving piece 111; finally, the force pressing rod 2 is released, and under the rebound force of the first return spring 82 and the second return spring 112, the pressing plate 63 is away from the blade 5, and the blade 5 is also away from the artificial leather 10. At this time, the artificial leather 10 is taken out, and a small size nose mask can be obtained.
