Abstract
The utility model relates to a rotary type hand-pushing knife which comprises a handle (6), a blade driving device (8), a knife disc (13), a blade (5), a rotating shaft (2), a washer (3), a rotating shaft seat (4) and a nut (11), wherein the knife disc (13) is positioned at the front end of the handle (6) and in a circular disc structure; the rotating shaft (2) sequentially penetrates the washer (3), the rotating shaft seat (4), the blade (5), the knife disc (13) and the blade diving device (8) and then is matched with nut (11) for mounting the blade (5) on the knife disc (13). The rotary type hand-pushing knife is characterized in that an axial wave crest-shaped bulge is arranged on the washer (3). The rotary type hand-pushing knife can effectively solve the technical problem that the blade is easy to sway left and right when the existing hand-pushing knife is used for cutting an object.
Description
Technical field
The utility model relates to a kind of rotary type hand-pushed cutter, specifically is meant a kind of rotary type hand-pushed cutter that can be used for cutting nonmetal things such as office paper, factory's nylon cloth.
Background technology
In the prior art, the blade shaft of rotary type hand-pushed cutter promptly directly is locked in blade on the cutterhead through screw rod to being generally stationary structure.The shortcoming of this structure is in use, and when the user imposed on the power generation deflection of hand-pushed cutter handle, blade for want of axial pre tightening force can produce and vacillates now to the left, now to the right, thereby influences cutting work and the user is brought certain potential safety hazard.
Summary of the invention
The utility model provides a kind of improved hand-pushed cutter, the easy wiggly technical problem of blade when having the hand-pushed cutter cutting object now to solve.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of rotary type hand-pushed cutter comprises handle, blade drive, cutterhead, blade, rotating shaft, packing ring, shaft seat, nut; The front end that cutterhead is positioned at handle is the circular discs structure; Rotating shaft is passed behind packing ring, shaft seat, blade, cutterhead and the blade drive through with cooperating of nut blade being installed on the cutterhead successively; It is protruding that said packing ring is provided with the axial wave peak shape.
As preferably, the axostylus axostyle cross section of said rotating shaft is " D " font, and the axostylus axostyle end is provided with the screw thread that is used for fixing rotating shaft, and this structure can prevent that when blade rotation, axostylus axostyle and blade rotate together.
As preferably, also be provided with hand protecting cover on the said handle, this structure has good anti-skidding effect, can play protective effect to user's hand simultaneously.
As preferably, said rotary type hand-pushed cutter also comprises the rotating shaft lid, and the rotating shaft lid is stuck on the bayonet socket of shaft seat through disposable buckle, and this structure is elegant in appearance, can also prevent effectively that rotating shaft from coming off.
Can find out according to such scheme and the utlity model has following advantage: one, packing ring has possessed certain elasticity; Can impose on axial pre tightening force of blade; Blade is very light when cutterhead is released or taken in like this; Because of the effect of elastic washer, blade can be close to cutterhead to blade, can not vacillate now to the left, now to the right when work simultaneously.Two, the axostylus axostyle cross section of rotating shaft is " D " font structure, and blade is when rotating, and rotating shaft can not followed rotation, thereby is not easy to make rotating shaft loosening, has strengthened the stability of rotating shaft.Three, also be provided with hand protecting cover on the handle, this structure has good anti-skidding effect, can play protective effect to user's hand simultaneously.Four, the rotating shaft lid is stuck on the bayonet socket of shaft seat through disposable buckle, and this structure is elegant in appearance, can also prevent effectively that rotating shaft from coming off.
Description of drawings
Fig. 1 is the utility model assembling sketch map.
Fig. 2 is the structural representation after the utility model assembling is accomplished.
Shown in the figure: 1, rotating shaft lid, 2, rotating shaft, 3, packing ring, 4, shaft seat, 5, blade, 6, handle, 7, button, 8, blade drive, 9, spring, 10, hand protecting cover, 11, nut, 12, nut cap, 13, cutterhead.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
A kind of rotary type hand-pushed cutter; Comprise handle 6, blade drive 8, cutterhead 13, blade 5, rotating shaft 2, packing ring 3, shaft seat 4, nut 11; Cutterhead 13 is positioned at the front end of handle 6, and rotating shaft 2 is passed packing ring 3, shaft seat 4, blade 5, cutterhead 13 and blade drive 8 back effects through nut 11 successively blade 5 is installed on the cutterhead 13; It is characterized in that: it is protruding that said packing ring 3 is provided with the axial wave peak shape; The axostylus axostyle cross section of said rotating shaft 2 is " D " font, and the axostylus axostyle end is got on the bus and is useful on the screw thread of fixed rotating shaft 2.Also be provided with on the said handle 6 and be used for hand protecting cover 10 anti-skidding and protection user hand.Said rotary type hand-pushed cutter also comprises rotating shaft lid 1, and rotating shaft lid 1 is stuck on the bayonet socket of shaft seat 4 through disposable buckle.Blade 5 all links to each other with blade drive 8 with cutterhead 13, under the effect of spring 9, can realize stretching out and contraction of blade through button 7, and is loosening in order to prevent nut 11, and nut cap 12 also is installed on nut 11.
According to above structure, in conjunction with accompanying drawing 2, when the actual use of the utility model; The user grasps handle 6, then presses button 7, and blade 5 just ejects from cutterhead 13 under the effect of blade drive 8; Begin then material to be cut is cut, in the process of cutting, blade 5 rotates with cut direction; Simultaneously under the effect of user's applied pressure, sever object, because the elastic reaction of packing ring 2, in the whole cutting process; Blade 5 receives the axial pre tightening force effect that packing ring 2 applies and is close on the cutterhead 13, and blade 5 is no longer vacillated now to the left, now to the right, thereby accomplishes the cutting task smoothly.In addition, in when cutting, though blade 5 can rotate, the axostylus axostyle cross section of rotating shaft 2 be " D " font, and rotating shaft 2 can be with blade 5 rotations, so that rotating shaft 2 can not produce because of the rotation of blade 5 is loosening.
Variation based on the utility model is not limited in above-mentioned embodiment, and multiple variation can also be arranged, and can make shell fragment or spring etc. into like packing ring.The effect that they are obtained is identical.These simple variations still belong to the protection domain of the utility model requirement.
