In the figure: 1-a tool holder body; 10-knife grooves; 2-a blade; 3-U-shaped frame; 4-a rotatable knife cover; 5-a rotating shaft; 6-handle bar; 7-magnet block.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
As shown in FIG. 1, the utility model provides a knife rest protection device, which comprises
The tool rest comprises a tool rest body 1, wherein a tool groove 10 is formed in the tool rest body 1;
a blade 2, the blade 2 is fixed in the cutter groove 10 through a blade fixing device; the blade fixing device is used for clamping or fixing two sides or end faces of the blade;
the U-shaped frame 3 is arranged at the top end of the knife rest body 1;
two rotatable knife covers 4, two rotatable knife covers 4 set up respectively in the top both sides of U-shaped frame 3, and rotatable knife cover 4 is located the top of blade 2. The blade cover is used for covering the blade 2, when slicing is carried out, the blade cover 4 can be rotated to enable the blade cover not to cover the blade, the top of the blade 2 is not covered, and the blade can be more smoothly operated.
The utility model has the advantages that:
the utility model discloses set up two rotatable blade covers on slicer knife rest, the finger can not be hurt to the blade in the time of the rotatable blade cover of control, has guaranteed the security of operation, and rotatable blade cover can prevent effectively that the blade from receiving external shock and damaging on the blade, has prolonged blade life, has also avoided the blade to operating personnel's the mistake injury of rubbing, simple structure, and is with low costs.
As a preferred embodiment of the present invention, the rotatable blade cover 4 is disposed on the U-shaped frame 3 through a rotation shaft 5.
As a preferred embodiment of the present invention, the one end of the rotating shaft 5 is connected with the handle 50, thereby the rotating shaft 5 is controlled to rotate to make the rotatable blade cover 4 rotate to cover the blade, the handle 50 is a control end, the finger does not contact with the blade 2 when the control is rotating, and the operation safety is ensured.
As a preferred embodiment of the present invention, the rotating shaft 5 rotates or slides left and right on the U-shaped frame 3. The two rotatable knife covers 4 can rotate and can be pulled apart to enlarge the exposed range of the blades, and the blades are not blocked during working.
As a preferred embodiment of the present invention, the two rotation shafts 5 are coaxial.
As a preferred embodiment of the present invention, the rotatable blade cover 4 is made of iron material, and the lateral portion of the blade holder body 1 is provided with the magnet block 6.
As a preferred embodiment of the present invention, when the bottom end of the rotatable blade cover 4 contacts the tool rest body 1, the magnet block 7 and the rotatable blade cover 4 attract each other. When the rotatable knife cover 4 covers the blade, the attraction of the magnet block 7 fixes the rotatable knife cover 4 to prevent the rotatable knife cover from rotating or sliding, thereby ensuring the stability and safety of the knife cover covering the blade.
As a preferred embodiment of the present invention, the total length of the two rotatable blade covers 4 is greater than the length of the blade 2. The blade 2 can be completely covered when the end surfaces of the two rotatable knife covers 4 are ensured to be contacted.
The utility model discloses a theory of operation:
when the slicing machine is finished, if the blade does not need to be taken down, the control hand lever enables the end surfaces of the two rotatable knife covers 4 to be contacted, the two rotatable knife covers 4 are rotated to enable the rotatable knife covers 4 to cover the blade 2, and the magnet block 7 attracts the rotatable knife covers to complete fixation.
When the slicing machine works, the hand lever is controlled to rotate the rotatable knife covers, so that the rotatable knife covers 4 rotate to the back surfaces of the blades, the hand lever is pulled towards the outward direction of the knife rest body, the two rotatable knife covers 4 are transversely displaced, the rotatable knife covers 4 are not positioned right above the blades any more, the blades are not shielded by the rotatable knife covers, and the working range of the blades is greatly expanded.
The above description is only an example of the preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and those skilled in the art should be able to realize the equivalent alternatives and obvious variations of the present invention.
