2, easy to operate, change quick;

3, can when not using, protect blade not stretch out, carry out cutting operation, more can effectively protect blade thus and blade is stretched out.

The present invention will further describe in detail through following specific embodiment, and further combine will obtain knowing more and significantly understanding to the explanation of accompanying drawing.

Description of drawings

Fig. 1 has shown the combination sketch map with dise knife of blade protective device of the present invention.

Fig. 2 has shown the decomposing schematic representation with dise knife of blade protective device of the present invention.

Fig. 3 has shown that the blade with dise knife of blade protective device of the present invention exposes state diagram.

The specific embodiment

Referring to Fig. 1 and Fig. 2, shown the specific embodiment with dise knife of blade protective device of the present invention.This dise knife 20 comprises handle 21 and the blade accommodation section 22 that is positioned at handle 21 front ends; This blade accommodation section 22 comprises the groove 23 that holds blade 30, and a side of this groove 23 is a part plectane 24, and this part plectane 24 is approximately the arc plate face of 120-160 degree; And the middle part of this part plectane 24 has annular protruding 241; Centre at this annular protruding 241 is provided with oval long through-hole 242, and the bottom of this groove 23 is an annulus base plate 26, and groove 23 has two ends 25 and 27; The another side of this groove is a part Circular Plate 28; The radian of this part Circular Plate 28 is identical with the radian of part plectane 24, and the inward at both ends of this part Circular Plate 28 is extended a flange 281 respectively, and this part Circular Plate 28 is provided with depression 283 and 284 near the position of this flange 281; This flange 281 forms stop portion 282 downwards; This blade 30 has manhole 301, this ellipse long through-hole 242, an elastomeric pad 61 and a nut 62 engagements that manhole 301, one bolts 60 pass this blade 30, thereby blade 30 is fixed in this groove 23.

Wherein, on blade 30, be coated with blade protective device 40, this blade protective device 40 comprises blade baffle and degree of tightness plate 50; This blade baffle comprises circular slab 41 that is positioned at the middle part and the notch board 42 that is connected through rib with circular slab 41, and notch board 42 be the part Circular Plate in this, the inside vertically extension of notch board in this; And extend flange 421 and 422 respectively at two ends; In this circular slab 41, be provided with the through hole that is passed by this bolt 60 and be provided with two fixed parts 412 and 413, these two fixed parts are respectively along the diameter symmetry setting, each fixed part comprise a swingle and from these swingle both sides to the lip-deep side plate that extends below and be connected to circular slab 41; Degree of tightness plate 50 is a long plate shape; One side of plate is provided with the accommodation section 511 and 521 that two swingles that can hold fixed part respectively pass, and this accommodation section can hold swingle in interior relative rotation, thus; This degree of tightness plate 50 can be around this swingle rotation rotating on circular slab 41; And the both sides of this degree of tightness plate 50 be provided with part Circular Plate 28 on depression 283 and 284 corresponding protuberances 53 and 54, on circular slab 41, rotate being fitted in 41 last times of circular slab this protuberance 53 and 54 and depression 283 and 284 engagements at this degree of tightness plate 52; Thereby make degree of tightness plate 50 bolt 60 rotations relatively; Make bolt 60 rotation relatively of blade baffle thus, and on the both side surface of degree of tightness plate 50, be provided with the convexity 55 and 56 that person easy to use grasps, and both sides one end of degree of tightness plate 50 is respectively equipped with the butting section 57 and 58 with the stop portion 282 corresponding settings of flange 281; Thus, degree of tightness plate 50 firm when the applying circular slab 41 further is provided.

In use, the position like needs adjustment blade baffle turns to the state (referring to Fig. 3) that blade is exposed as being positioned at guard mode shown in Figure 2, can the degree of tightness plate be mentioned through convexity; After making the degree of tightness plate perpendicular to circular slab, rotation degree of tightness plate is behind the inside Rotate 180 degree of driving blade baffle; Interior notch board is hidden in the groove, and blade exposes, and can carry out work; At this moment the degree of tightness plate is put down, the protuberance of degree of tightness plate and butting section cooperate with depression and stop portion on the part Circular Plate, stop the rotation of baffle; Behind end-of-job, otherwise both can move, and make baffle be positioned at the position of protection blade.

Through foregoing description, the present invention can effectively protect blade, has not only prolonged service life, also is convenient to safeguard and change.

It is obvious that, and above description and record only are for example rather than in order to limit disclosure of the present invention, application or use.Though described and be described in the drawings embodiment in an embodiment; But the optimal mode that the present invention does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present is with the specific examples of the instruction of embodiment of the present invention, and scope of the present invention will comprise any embodiment of the specification that falls into the front and appended claim.
