For 1.8mm, the bottom knife than existing 1.5mm is thick, and the probability deformed upon reduces very much, reliability height.
As shown in figure 5, the interior sliding of sliding slot above the front end of fuselage 100 is provided with a cutter head block 13, cutter head block
Spring 12 is equipped between 13 and fuselage 100.The front end of the shell 14 of fuselage 100 is equipped with card slot 241.
Such as Fig. 4, shown in Fig. 2, the top of cutter head 16 sets that there are one fixture blocks 24.
When actual installation cutter head, fuselage 100 is taken on the other hand, pinches the non-slip parts on cutter head 16 with thumb and index finger on the other hand
25 (hand tries not to encounter blade) insert the alignment fuselage 100 of cutter head 16, do not have to deliberately notice whether upper slitter insert 23 is right
The accurate card slot 110 of swing component 11, cutter head block 13 can be by the upper surface of cutter head 16 to the pusher such as arrow sides Fig. 2 in insertion process
To when fixture block 24 is embedded in card slot 241, cutter head block 13 can reset under the effect of spring 12, and upper slitter insert 23 is also inserted into
In the swing component card slot 110 of swing component 11, to which cutter head 16 connect such as Fig. 1 with fuselage 100, shown in Fig. 3.
Since cutter head block 13 can stretch reset, so play guiding positioning action during the installation process, no matter on
Knife insert 23 and swing component 11 are in which kind of angle or height, as long as being substantially aligned with, as long as cutter head block 13 resets, and fixture block 24
In embedded card slot 241, the relative position of each component is just accurately fixed up.
Lower cutter head 16 is unloaded, as long as a hand handle cutter head block 13 makes its end be detached from shelves groove to Fig. 2 arrow directions such as are pushed back
24, the thumb and index finger of the other hand pinch the non-slip parts 25 of cutter head 16 the extraction outward of cutter head 16.
As it can be seen that the utility model handling cutter head 16 do not need tool, as long as and installation cutter head 16 when be substantially aligned with, ten
It is convenient to divide.
Such as Fig. 1, two cutter head screws 101 can be reused with user and lock cutter head 16, lock and withstand fuselage 100, from
And improve the connection reliability of cutter head 16 and fuselage 100.
As shown in figure 3, when the utility model is used, pressing motor switch 1, power source body 26 is powered to motor 5, and motor 5 is logical
It crosses speed reducer 6 and eccentric head 8 is driven to rotate, the eccentric part of eccentric head 8 drives movement square 9 and circular motion is converted to directly
Line moves and swing component 11 is driven to move up and down in swing component guide groove 10, upper in the swing component card slot 110 of swing component 11
Knife insert 23 just moves up and down, and to which cutter 21 is rotated around hinged shaft 19, shearing work is completed in conjunction with motionless bottom knife 22.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
The difference of embodiment, just to refer each other for identical similar portion between each embodiment.To the upper of the disclosed embodiments
State it is bright, enable professional and technical personnel in the field realize or use the utility model.Various modifications to these embodiments pair
