In order to solve the above technical problems, a kind of metal cutter of the utility model, on the rotating shaft, the metal is cut for setting
Knife includes several blades, and protective device is provided between the blade and the rotation axis, and the protective device includes that fixation is set
Set the transmission parts in the rotation axis, the transmission parts and the relatively turnable connection of the blade, two neighboring institute
It states and is provided with elastic conductive part between blade, when cutting is more than the hard material of setting hardness, the blade is in the promotion expected firmly
Lower that the elastic conductive part is deflected and compressed toward anti-cut direction until being disengaged with the hard material, the elastic conductive part is multiple
The position blade is to its initial position, i.e., protective device can get around hard hard material, and need not shut down and can be used continuously, together
When blade is protected, service life is long, so that blade is being cut by protective device between each blade and rotation axis
Cutting the when of encountering the hard material more than setting hardness makes transmission failure between blade and rotation axis, thus when not easily damaged, replacement
It only needs that damaged blade exchange to get off, replacement cost is low.
The transmission parts and the blade are hinged.
The transmission parts include transmission main body and with the fixed annulus of the transmission main body, the annulus fixes and is set in
In rotation axis.
The fixing piece that is radially provided with of the annulus is fixed with the rotation axis.
The transmission parts are integrally formed with the rotation axis.
The transmission parts uniform ring is arranged around the rotation axis.
The elastic conductive part is spring.
The blade is provided with evacuation cambered surface on the cutter hub at the rotation axis, for preventing the blade traditional method of indicating the pronunciation of a Chinese character from cutting
Interference is generated when direction deflects.
Frosting is provided at the non-blade of blade cutting side, i.e. blade passes through setting frosted on the face at blade
Face can play the effect for facilitating cutting to detach, and improve cutting efficiency.
The blade include cutter hub and with the integrally formed knife ring of the cutter hub, the knife ring be suitable for be set in the rotation
On axis, i.e., in transmission failure, knife ring can relatively rotate shaft rotation and move, that is, facilitate the fixed enabling for facilitating protective device again.

Specific implementation mode
Embodiment 1
Fig. 1 show the metal cutter in the present embodiment, and metal cutter includes several blades 1, and the volume cost of blade is implemented
Example is 4, but is not limited to the quantity, and protective device 3 is provided between blade 1 and rotation axis 2, and protective device 3 includes that fixation is set
The elastic conductive part 33 set the transmission parts 32 in rotation axis 2 and be arranged between two neighboring blade 1, the elastic conductive
Part 33 is spring, 1 relatively turnable connection of transmission parts 32 and blade, as shown in Fig. 2, the present embodiment will by articulation piece 6
Transmission parts 32 and blade 1 are hinged, and articulation piece 6 is a screw and a nut, can also be other modes, such as rivet.When cutting
When cutting hard material 4 more than setting hardness, blade 1 is under the promotion of hard material 4 toward the deflection of anti-cut direction and elasticity of compression conducting piece
33 with hard material 4 until disengage, elastic conductive part 33 resets blade 1 to its initial position.
