Referring to Fig. 1-3, a kind of Safety cutter head of the utility model, including mounting bracket 1, guard 2, moving knife component 3, setting exist
For movable knife disc 301 to be limited the limiting component in mounting bracket 1 on mounting bracket 1, limiting component can be an element or more
A element.
Guard 2 is fixed on mounting bracket 1, that is to say, that guard 2 is relatively-stationary with mounting bracket 1, and guard 2 can be with
It is fixed on mounting bracket 1 by the various modes such as crimping, being clamped, mounting bracket 1 is tubular structure and both ends open, and guard 2 will pacify
It shelves 1 open end to cover, is covered with aperture on guard 2.
Moving knife component 3 is movably arranged in mounting bracket 1 so that moving knife component 3 can rotate in mounting bracket 1, movable cutter set
Part 3 includes movable knife disc 301 and the cutting blade 302 on movable knife disc 301, and cutting blade 302 has multiple, is set on movable knife disc 301
It is equipped with the interconnecting piece 3011 for being detachably connected with driving mechanism, is determined when the interconnecting piece 3011 on movable knife disc 301 is placed through
After the through-hole 401 at position 4 centers of circle is connected with the driving mechanism on host, driving mechanism can drive movable knife disc 301 to rotate,
The cutting blade 302 allowed on movable knife disc 301 rotates, in this way, when shaving, beard is extend by the aperture on guard 2
In guard 2, at this point, cutting blade 302 cuts off the object extending into guard 2, to complete to cut.
Interconnecting piece 3011 is an open tubular column, and the endoporus of the open tubular column is hexagonal structure, correspondingly, the driving machine on host
The drive shaft of structure is also hexagonal structure, and when interconnecting piece is connected with driving mechanism, the drive shaft of driving mechanism is inserted into
Into the endoporus of the open tubular column, in this way, driving mechanism can drive movable knife disc 301 to rotate, by interconnecting piece 3011 and driving mechanism
When phase separation, which is pulled up from the drive shaft of driving mechanism.
Limiting component is removably arranged on mounting bracket, in this way, after disassembling cutter head from host, can incite somebody to action
Limiting component is removed from mounting bracket 1, then can remove movable knife disc 301, thus can be easily to 301 He of movable knife disc
Cutting blade 302 on movable knife disc 301 is cleaned, and after removing movable knife disc 301, can conveniently guard 2 it is interior
It is cleaned on surface.
Limiting component is a locating ring 4, and when locating ring 4 is inserted into mounting bracket 1, locating ring 4 passes through 402 band of elastic pressuring plate
The dynamic protrusion 403 positioned at 402 one end of elastic pressuring plate is moved along 1 inner wall of mounting bracket, when protrusion 403 is fixed on the annular outside guard
On fixed part 201, protrusion 403 will be embedded in mounting bracket inner card cage 103, and moving knife component 3 is just limited in locating ring 4 and guard
Between 2, can very easily locating ring 4 be taken out and be cleared up 2 inside of guard, the spy of locating ring 4 after removing cutter head
Point is that it makes molding for elastic stainless steel material, to the elasticity of itself and positioning moving knife after dismantling and being packed into repeatedly repeatedly
Component 3 is barely affected, and it is more preferable that this allows for its position stability, is influenced to moving knife component 3 due to will not be after repeatedly dismantling
Limit effect.
Mounting bracket 1 includes the first ring 101 and the second ring 102, and one end of the first ring 101, which is provided with, radially-inwardly prolongs
The annulus 1011 stretched, the week of guard 2, annular fixed part 201 was interior with annulus 1011 along annular fixed part 201 is above provided with
Surface fits, and the second ring 102 is fixed in the first ring 101, and the end face of the second ring 102 is pressed on annular admittedly
Determine in portion 201.
After using the above structure, the utility model has the following advantages that with existing structure comparison：
1. a kind of Safety cutter head of the utility model, due to being provided on mesh sheet mounting bracket for limiting moving knife component
Positioning coil component in mesh sheet mounting bracket only need to be by mesh sheet mounting bracket and host in this way when cutter head to be assembled on host
It is connected, while the coupling part on moving knife component is connected with the driving mechanism on host, in this process, movable cutter set
Part is always positioned in stationary knife component so that the cutting blade on moving knife component will not expose, in this way, cutting blade will not scratch human hand；
And when disassembling cutter head from host, mounting bracket is detached with host directly and then removes mounting bracket, at this point, dynamic
Knife assembly even be removed, even if the driving mechanism on host can not also drive moving knife if working at this time together with mounting bracket
Cutting blade rotation on component, can damage human hand to avoid cutting blade.
2. after head assembly is removed from host, locating ring for fixing can after the removing of relative ease so as to
To being cleaned in mesh sheet, locating ring itself has preferable elasticity, can dismantle repeatedly makes because being Five-gold-sheet molding making
With.
