Specific embodiment
The utility model is described further below in conjunction with Figure of description.
It picture 1-4, is three kinds of embodiments of the cutter of the more allowing blade replacement of the utility model shown in Fig. 5-6, Fig. 7-8, they
It include handle 01, the blade holder 02a/02b/02c set on handle front end, the blade 03 that is assemblied in blade holder, blade holder
02a/02b/02c has notch 21 backwards to constrain by interruption, and the edge of blade 03 is surrounded by knife rest and in indentation, there
Exposed portion blade, blade holder 02a/02b/02c include blade shelves 22a/22b/22c and are assembled in blade shelves
Lid 23a/23b/23c, lid 23a/23b/23c, which are covered, constrains in blade holder for blade on blade shelves 22a/22b/22c
On, lid, which is opened, from blade shelves exposes blade then with more allowing blade replacement.
Specifically, embodiment one, Fig. 7-8 illustrated embodiment three, the front end of handle 01 are equipped with facing forward insert as shown in Figs 1-4
Hole 11 and connection spliced eye and the open lateral locking hole 12 in handle surfaces are connect, blade holder has plug division 24, plug division 24
Lateral flexible latches 25 are equipped with, plug division 24 is inserted into spliced eye 11, and flexible latches 25 are located at lateral locking hole
In 12, flexible latches are pressed into lateral locking hole, flexible latches is enabled to deviate from lateral locking hole to extract blade holder.In order to
Increase the intensity (handle is adopted made of plastic) at lateral locking hole, structural strengthening inserts 215 be equipped in the handle at the position,
Likewise, in order to increase intensity, it can also be in other positions (in such as blade shelves and lid) adding structural reinforcer.
Further, embodiment one as shown in Figs 1-4, blade shelves 22a, lid 23a are plate-like piece, blade placement
The side of frame 22a is equipped with blade placing groove 26, and lid 23a passes through the lateral pin shaft 27 and blade set on blade shelves front edge
Shelves 22a rotation connection, lid 23a are covered on the blade side shelves 22a and constrain in blade 03 in blade placing groove,
It raises lid and exposes blade to replace, plug division 24 includes the first plug division 28 on the blade shelves 22a and is set to lid
The second plug division 29 on sub- 23a, the first plug division 28 and the second plug division 29, which are closed up, to be inserted into spliced eye 11.Therefore, it is intended to
When more allowing blade replacement, must will remove on handle in blade holder can open lid replacement blade, and before blade holder is assemblied in handle
When end, lid cannot be opened, it is possible thereby to reliably constrain blade.
Since blade is relatively thin, when placing it in blade placing groove, not easy-to-use hand taking-up is replaced, what is more,
Since grease would generally be coated on blade, thus cause blade that can be adhered to blade placing groove, and it is in use, it can be because of dust
Etc. foeign elements by blade card in blade placing groove, be not easily taken out blade.Therefore, in Fig. 1-4 illustrated embodiment one, blade is placed
The position of the adjacent lateral pin shaft 27 in the edge of slot 26 is equipped with notch 210, and the position that notch is corresponded on lid 23a is equipped with top tongue 211,
Opening lid period of the day from 11 p.m. to 1 a.m top tongue 211 jacks up at the edge of blade 03 via notch 210 out of blade placing groove, to take out knife with hand
Piece.
Mode is raised according to lid, if the opening lid period of the day from 11 p.m. to 1 a.m does not limit the rotational angle of lid, pushing up tongue will excessively turn
It moves and leads to push up tongue from blade edge slippage, blade can fall again into blade placing groove, moreover, even if taking blade in this state
It replaces out, then in close the cover, the edge of blade can stop to push up tongue, cause lid that cannot close.Therefore, implement shown in Fig. 1-4
In example one, blocking portion 212 is equipped on lid 23a, opening lid period of the day from 11 p.m. to 1 a.m blocking portion 212, which contradicts on blade shelves 22a, to be hindered
Only push up 211 excess rotation of tongue and cause push up tongue from blade edge slip, it is ensured that when lid raises maximum angle push up tongue be maintained at by
The state that the edge of blade is jacked up out of blade placing groove.
Embodiment two as seen in figs. 5-6, lateral one end of blade shelves 22b is rotatablely connected through vertical pin shaft 213 to be covered
Sub- 23b, perpendicular to blade, blade shelves 22b is equipped with blade and inserts gap the vertical pin shaft, and blade inserts the one end in gap
It is open and towards lid 23b, blade inserts the other end closing in gap, and lid, which is covered, constrains in knife for blade in blade shelves
Piece inserts in gap, and the one end for opening lid exposing blade is replaced with extracting blade.
Embodiment three as Figure 7-8, blade shelves 22c, lid 23c are plate-like piece, blade shelves 22c with
Handle 01 is made as one, and the side of blade shelves 22c is equipped with blade placing groove, the back edge of lid 23c through lateral pin shaft with
Handle 01 is rotatablely connected, and the leading edge of lid 23c and the leading edge snapping of blade shelves 22c, lid are covered on blade placement
Frame side simultaneously constrains in blade in blade placing groove, raises lid and exposes blade to replace.Specifically, the front of lid 23c
Edge is equipped with hook 214, and hook 214 hooks when lid is covered on blade shelves side and constrains in blade in blade placing groove
The leading edge of blade shelves 22c realizes snapping.
Picture 1-4, three embodiments shown in Fig. 5-6, Fig. 7-8, blade 03 are in isosceles trapezoid, are made on the long bottom edge of blade
Blade out.
The tail portion of handle 01 is equipped with tail nail 13, for puncturing the joint sealing object of the packing cases such as similar film, adhesive tape；Handle 01 by
First shank body 14 docks composition with the second shank body 15, and pillar, another shank body are set in a shank body when it is implemented, can be
On set corresponding blind hole, pillar is inserted into and realizes and docks in blind hole, can will be convex by binder in order to guarantee bonding strength
Column gives be bonded with the inserting position of blind hole, the first shank body with the docking site of the second shank body, and tail nail 13 is fastened by fastener 16
It is clamped in a shank body and by the first shank body and the second shank body, guarantees that tail follows closely the assembly intensity on handle.
