Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the overall structure figure of cartilage shredder bar.A shaft 11 is equipped in shredder bar main body 1, shaft 11 is hung down
Directly in the section of shredder bar main body 1.Motion bar 2 has a circular opening, and the diameter of circular opening is identical as the diameter of shaft 11,
Shaft 11 is inserted in the aperture of motion bar 2, rotates motion bar 2 on the section of cutting bench main body 1, forms pivot joint.Pivoting point
Positioned at the middle position of main body 1, shredder bar main body 1 and the pivot joint of motion bar 2 form lever, facilitate pressing.One end phase of motion bar 2
Blade 3 is had, motion bar 2 interlocks the pushing of blade 3 and cut.Shredder bar main body 1 is equipped with auxiliary cutting bed 4, auxiliary cutting
Platform 4 is located at the underface of blade 3, and auxiliary cutting bed 4 is a prismatoid.Auxiliary cutting bed 4 is surrounded by baffle 43, to needs
The cartilage block of cutting is fixed, and prevents from skidding off cut coverage in cutting, lower pushing broach 3 makes cartilage block in auxiliary cutting bed 4
On cut, realize the effect quickly shredded.
Blade 3 is installed on tool apron 10, has stroke lever 8 on tool apron 10, and stroke lever 8 and tool apron 10 are integrally formed, stroke
The other end of bar 8 is connected with briquetting 7, and briquetting 7 is a block-like cuboid of elasticity.Stroke lever 8 have screw thread, briquetting 7 have with
The aperture of the identical screw thread of stroke lever 8, briquetting 7 are connected through a screw thread with stroke lever 8.Motion bar 2 is driven tool apron by pressing briquetting 7
Blade 3 on 10 is cut.The length of stroke lever 8 is the mobile maximum distance of blade 3, and stroke lever 8, which plays, limits 3 row of blade
The effect of journey.The insertion of briquetting 7 moves the guided way 5 being oriented to it, and guided way 5 is the runner of four squares, pastes respectively
Tightly in four vertex of briquetting 7, briquetting 7 is made to be embedded in guided way 5, makes briquetting 7 in guided way 5 pressing of briquetting 7 by motion bar 2
It moves up and down.The lower end of guided way 5 is equipped with limit plate 6, and limit plate 6 is a sheet metal, and center has an aperture, and stroke lever 8 is worn
Aperture connection briquetting 7 is crossed, for limiting the depression distance of briquetting 7.Limit plate 6 is fixed in shredder bar main body 1, limit plate 6
It is parallel to horizontal plane.Guided way 5 is fixedly welded on 6 top of limit plate, and guided way 5 is perpendicular to horizontal plane, so that motion bar 2 presses
Briquetting 7 vertically declines.Spring is mutually had between briquetting 7 and limit plate 6, can be resetted after being pressed briquetting 7.Passing through will
Cartilage block is placed on auxiliary cutting bed 4, when pressing motion bar 2, interlocks blade 3 downwards close to cutting secondary station 4, thus to soft
Bone block carries out netted cutting, substantially increases the efficiency of cutting.
