Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Shown in Fig. 1, the present invention includes fuselage 1, the rear handle 2 of the afterbody of fuselage 1, the handle 5 of the top of fuselage 1, the front end of fuselage 1 Head capsule 4, two groups of the both sides of head capsule 4 circular blades 7.
Motor 11 is provided with fuselage 1, the switch 3 of motor 11 is located on rear handle 2, and motor 11 is by dc-battery or exchange Electric drive.Design is existing basic engineering part above.
Shown in Fig. 2, motor 11 is provided with transmission mechanism into head capsule 4, and transmission mechanism includes：
First master gear 12, the second master gear 13, drive link 14, driving bevel gear 15 and two driven bevel pinions 16.The One master gear 12 is connected on the motor shaft of motor 11, the second master gear 13 be connected to one end of drive link 14 and with the first main tooth The engagement of wheel 12, the other end connection driving bevel gear 15 of drive link 14, the second master gear 13, drive link 14, driving bevel gear 15 Three is concentric.Two driven bevel pinions 16 and the engaged transmission of driving bevel gear 15, driven bevel pinion 16 coaxially connect with blade 7 Connect, the axis of two driven bevel pinions 16 is vertical with the axis of driving bevel gear 15 respectively, while two axis of driven bevel pinion 16 Between form 60 degree or 90 degree or 120 degree of angle.First master gear 12, the second master gear 13, drive link 14, driving bevel gear 15 and two driven bevel pinions 16 be limited in head capsule 4.
Due to forming angle between two axis of driven bevel pinion 16, therefore, two groups of blades 7 being attached thereto, which are also formed, to be cut Cut angle, described two groups of blades 7 are in the shape of the letter V ornaments, and the bottom of two groups of blades 7 is relative to be drawn close.The structure fluting when, make by The bulk that the building stones of cutting are V-shaped comes off, and is not likely to produce chip and dust.Meanwhile the line of rabbet joint cross section opened is also V-arrangement, Wiring and during pipeline in the line of rabbet joint of this V-arrangement, line and pipeline, which are compressed downwards, can find suitable locking position, prevent line and Pipeline loosens.
Every group of blade 7 can be monolithic or multi-disc superposition.
Secondly, shown in Fig. 4, the thrust point of center line and rear handle 2 between two groups of blades 7 is in same straight line.This Sample stability under loading, biasing force will not be produced, because the blade 7 of this angle design, easily bursts apart in stress off normal.Described Handle 2 can be the handle of strip-like-shaped handle or U-shaped afterwards, when being arranged to the handle of U-shaped, the rear energy of handle 2 and machine 1360 degree of rotations of body.
Single protective cover is equipped with two groups of blades 7, described protective cover is divided into two-part；Protective cover 28 and head capsule 4 It is relatively fixed, the relative folding of protective cover 28 of the energy of protective cover 1, or, protective cover 1 can rotate with protective cover 28 be superimposed, and protect Lock screw 8-1 is provided between shield 1 and protective cover 28, the position of its folding is fixed.Protective cover 28 covers blade 7 Area is not more than a quarter, and when protective cover 1 is opened, such structure can make the front end of blade 7 when cutting right-angled bend Formed and cut without dead angle.
Described head capsule 4 is provided with benchmark harden structure, and shown in Fig. 3, benchmark harden structure includes bottom plate 9, stretch rod 18, regulation Screw rod 20, spring 19.The stretch rod 18 passes through head capsule 4 and the relative head capsule 4 of energy is up and down, the lower section of stretch rod 18 and bottom plate 9 It is connected, energy belt bottom moves up and down.The top of stretch rod 18 is provided with rib, axial direction and the activity side of stretch rod 18 of adjusting screw rod 20 To rib identical and through stretch rod 18, the head of adjusting screw rod 20 is threadedly coupled with head capsule 4, and the afterbody of adjusting screw rod 20 is Positive stop end 17 is used for the activity for limiting stretch rod 18.Spring 19 is cased with adjusting screw rod 20, spring 19 is in head capsule 4 and stretch rod Between 18 rib, the rib of stretch rod 18 is sandwiched in centre by spring 19 and positive stop end 17.
Bottom plate 9 has spacing with 7 minimum position of blade, and spacing is default groove depth.
Such as：During regulation, adjusting screw rod 20 is rotated, adjusting screw rod 20 is screwed in head capsule 4, while the length of adjusting screw rod 20 Degree changes.Because stretch rod 18 is limited on adjusting screw rod 20, therefore stretch rod 18 moves downward with bottom plate 9, bottom Plate 9 and the spacing at 7 minimum position of blade diminish.Above-mentioned spring 19 is against at the rib of stretch rod 18, can play damping Effect, for example, on the wall, fuselage 1 can shake face patch in fluting, if without spring 19, then reference plane on the basis of bottom plate 9 It can be beated with fuselage 1.The design of this damping is in order to which bottom plate 9 and fuselage 1 are changed into two independent main bodys, fuselage 1 and knife The vibrations of piece 7 are unlikely to feed back on bottom plate 9.
The lower section of head capsule 4 is additionally provided with catch 10, and catch 10 is be hinged with head capsule 4, the ornaments direction of catch 10 and the axle of hinged place To vertical with motor direction of principal axis, the lower edge of catch 10 hangs on bottom plate 9 automatically, and catch 10 is in the rear of bottom plate 9, and Close to the rear side of handle 2.Or the hinged place of catch 10 is provided with torsion spring.Because bottom plate 9 is a piece of smooth platy structure, therefore Rubble can be retrojected and got rid of by blade 7 when rotating, and catch 10 is to stop the rubble for retrojecting and getting rid of.
Bottom plate 9 is provided with notch 9-1, and notch 9-1 extends internally from the lateral margin of bottom plate 9, and blade 7 inserts from notch 9-1, The front end of blade 7 is in the outside of bottom plate 9, and the rear end of blade 7 is in notch 9-1.This groover due to being v-shaped structure blade 7, Therefore, blade 7 can not be press directly against cut surface, so have the consequence for collapsing knife, therefore, it is necessary to the front end of blade 7 is first cut In wall, then main body turning 1, makes bottom plate 9 be pressed on metope, then promotes groover, to reach the effect of straight cuts.
