As shown in fig. 2-6, the follow-up traction mechanism is a flexible socket type traction mechanism; the flexible socket joint type traction mechanism comprises a flexible pen cap 4 fixed in the middle of the upper end of the substrate 1; the flexible pen cap 4 is of a conical structure; the outer side wall of the flexible pen cap 4 is provided with an indicating mark 5 which is consistent with the cutting direction of the arc-shaped knife 3; a micro linear vibration motor 6 and a micro storage battery 7 are fixed on the upper part of the substrate 1; the micro storage battery 7 is used for supplying power to the micro linear vibration motor 6; the vibration direction of the miniature linear vibration motor 6 is parallel to the cutting direction of the arc-shaped knife 3; a charging seat 8 is arranged outside the substrate 1; a dry battery 9 for supplying power to the micro storage battery 7 is arranged in the charging seat 8; a protection groove 10 is arranged on the charging seat 8; the protection groove 10 corresponds to the substrate 1; a positioning magnetic block 11 is fixed in the substrate 1; the charging seat 8 is fixed with a magnetic absorption block 12; the positioning magnetic block 11 is correspondingly magnetically connected with the magnetic attracting block 12.
As shown in fig. 7 to 9, the base plate 1 includes an upper support case 13 and a lower turntable 14; the inlay 2 comprises an upper inlay 15 embedded outside the support shell 13 and a lower inlay 16 embedded outside the turntable 14; the follow-up traction mechanism is a universal rotary traction mechanism; the universal rotary traction mechanism comprises a fulcrum shaft 17 coaxially fixed at the upper end of the turntable 14; the fulcrum shaft 17 is coaxially and rotatably connected with the supporting shell 13; the arc-shaped knife 3 is fixed on one side of the lower end of the rotary table 14 and deviates from the axis position of the rotary table 14; a nib groove 18 is formed in the middle of the upper end of the supporting shell 13; a protection box 19 for protecting the arc-shaped knife 3 is correspondingly arranged outside the base plate 1.
The conventional cutting tool 20 usually uses a blade point part when cutting wrong extraction problems, the sharp point of the blade point is used for firstly pricking the paper 21, and then the blade part is slid to cut the paper 21, however, the blade point is sharp but easily broken, as shown in fig. 10, once broken, the paper 21 is not smoothly pricked at the beginning, so that the subsequent cutting is not so smooth and convenient; in addition, the problems that the conventional cutting tool 20 is easily injured, easily cuts the lower paper 21, and is inconvenient in cutting and turning are also obvious.
Furthermore, the paper 21 can be regarded as a multi-layer structural form in the thickness direction, the cutting edge cuts the paper 21 in a layer-by-layer progressive manner, as shown in fig. 11, if a cutting tool 20 with a conventional flat cutting edge is used, it is required that the smaller the pre-cutting angle formed between the cutting edge and the paper 21 is, the better the pre-cutting angle is, so that when the cutting edge is stroked, the fewer the layers of the paper 21 which are mutually pulled and influenced in the thickness direction are, and the paper 21 is less prone to wrinkle or tear, otherwise, when the pre-cutting angle is larger, the more the layers of the paper 21 which are mutually pulled and influenced in the thickness direction are increased, and the tearing strength caused by pulling is increased, so that the paper 21 is easy to wrinkle and tear, and the extraction effect is affected.
The cutting tool 20 used in the technical scheme is the arc-shaped cutter 3, the diameter of the arc-shaped cutter 3 is only 2mm-3mm, the lower end of the arc-shaped cutter 3 only penetrates out of the lower end of the inlay 2 by 0.07mm, and the arrangement structure is not purposeful but has important purposes:
first, the arc-shaped knife 3 is shaped such that the blade portion is also arc-shaped, and when the arc-shaped knife edge cuts the paper 21, no matter how the knife edge swings in the direction, the pre-cutting angle is along the tangential direction of the contact point between the knife edge and the paper 21, that is, the pre-cutting angle is small (close to 0 °), so that no matter what angle the arc-shaped knife 3 swings to cut, the problem that the paper 21 is wrinkled or torn during cutting does not occur.
Second, the thickness of the conventional paper 21 is substantially between 0.07mm and 0.1mm, so that the lower end of the curved blade 3 is only 0.07mm through the lower end of the inlay 2, thereby ensuring that the underlying paper 21 is not cut. Of course, if the thickness of the sheet 21 slightly exceeds 0.07mm, the sheet 21 may not be cut completely, but may be cut with deep scratches, and the portion to be extracted can be removed easily.
Thirdly, the shape of the arc-shaped knife 3 is combined with the arrangement that the volume of the arc-shaped knife 3 is very small and the penetrating part is very short, so that the arc-shaped knife 3 can be cut and turned more conveniently, the problem of 'cutting over' or 'not cutting in place' is not easy to happen, and the problems of breakage, damage and scratch of the arc-shaped knife 3 are not easy to cause.
Of course, this device is very small and exquisite, especially arc sword 3 part, but according to present processing technology, the degree of difficulty of getting up in production is not high, even the part that arc sword 3 wore out from inlay 2 lower extreme is only 0.07mm, according to present technological means, no matter fix arc sword 3 earlier and cover inlay 2 again, cover inlay 2 earlier and then penetrate arc sword 3 and all can reach comparatively easily.
Example 1:
in this embodiment, install flexible cup joint formula drive mechanism on base plate 1, as shown in fig. 2-3, can tightly overlap pen point department with writing pen 25 through flexible pen socket 4 (can adopt the transparent silica gel material), and set up the direction unanimous indicator 5 with the 3 cutting directions of arc sword at 4 lateral walls of flexible pen socket, like this when cutting paper 21, just can relax the removal through writing pen 25, accurate realization is to the cutting of paper 21 (turning to when cutting), base plate 1 sets up to the ball arc, inlay 2 adopts the special fluorine dragon material, make the cutting move and the angle swing more smoothly.
The vibration direction of the miniature linear vibration motor 6 is parallel to the cutting direction of the arc-shaped knife 3, so that the amplification effect on the cutting of the arc-shaped knife 3 can be achieved, and the cutting is more efficient. The miniature storage battery 7 can be conveniently charged at any time through the charging seat 8, and the dry battery 9 which is low in cost and can be replaced at any time is selected as the power supply source in the charging seat 8, so that the device is more favorable for popularization of students, and the practicability is enhanced; in addition, the substrate 1 is fixed in the protection groove 10 by adopting the corresponding magnetic connection of the positioning magnetic block 11 and the magnetic attraction block 12, so that the substrate can be taken out and fixed more conveniently, and as shown in fig. 5-6, the charging contact 22 of the micro-battery 7 and the power supply contact 23 of the dry battery 9 can be aligned more accurately.
Example 2:
as shown in fig. 7-8, in the present embodiment, a universal rotary type traction mechanism is adopted, and by using the way that the arc-shaped knife 3 deviates from the axis of the fulcrum shaft 17, when the writing pen 25 drives the substrate 1 to move, the turntable 14 is forced to rotate along with the force until the cutting direction of the arc-shaped knife 3 is consistent with the moving direction of the writing pen 25, so that a control mode of "knife-following-movement" is realized, instead of the control mode that the writing pen 25 needs to conform to the cutting direction of the arc-shaped knife 3 in embodiment 1, on this basis, the pen point of the writing pen 25 only needs to be placed in the pen point groove 18 in the present embodiment. Of course, in order to make the orientation of the arc-shaped blade 3 follow more smoothly, the portion of the fulcrum shaft 17 rotatably connected to the support case 13 may be fitted with the ball 24.
