The specific embodiment

Below in conjunction with accompanying drawing enforcement of the present utility model is described.

See Fig. 1, Fig. 3, the utlity model has housing 1, by bearing 7 rocking bar 5 is installed on the housing 1, one end of described rocking bar 5 is the rotating shaft that is connected with the drill bit installing hole, the other end has an inclined-plane 4, the angle α that inclined-plane 4 is become with vertical direction be 5 spend to 30 the degree between, present embodiment get 20 the degree.Inclined-plane 4 is provided with the connecting axle 16 of one, and connecting axle 16 is preferably vertical with inclined-plane 4.Connecting axle 16 is connected with the upper end 17 of fork 3 by locking nut 2, the both ends of the surface of fork 3 upper ends 17 flexibly connect by ball respectively and between the end face of the inclined-plane 4 of described rocking bar 5 and locking nut 2, to reduce the friction between the contact-making surface, the noise when reducing work.See Fig. 1 to Fig. 3, specifically can be at the groove 19 that has annular on the inclined-plane 4 of the both ends of the surface of fork 3 upper ends 17 and rocking bar 5 around near fork upper end 17 centre bores, 19 devices of groove ball; The end face of the nut 2 that contacts with fork 3 upper ends 17 also has corresponding grooves, the inside device ball of groove.See Fig. 1, Fig. 2, the lower end 18 of fork 3 flexibly connects by roller 12 with an end of slide bar 13, and roller 12 flexibly connects with slide bar 13, specifically can have the roller hole of fore-and-aft direction in slide bar 13, and roller 12 inserts in the described hole; In slide bar 13 and roller 12, have the fork hole of above-below direction, the fork hole of the above-below direction that has in slide bar 13 is opposing direction and has bell-mouthed mounting hole, the above-below direction that in slide bar 13, has the fork hole and the roller hole of the fore-and-aft direction that has vertically communicate, the lower end 18 of fork 3 inserts in the fork hole of the above-below direction that has in the described roller 12.Fig. 1, Fig. 2 illustrate the axis normal of the lower end 18 of the axis of upper end 17 of fork 3 and fork 3.The other end device chuck 14 of slide bar 13 can install multiple cutter in the chuck 14, for example saw blade, file and so on, and device has saw blade 15 among Fig. 1.Slide bar 13 be installed on casing be in the guide pin bushing 11 of one.The axis that Fig. 3 illustrates connecting axle 16 is positioned at first position on inclined-plane 4, so can make the upper end of fork 3 be in the housing 1 by the top position, the best is that the axes intersect of the axis of the connecting axle 16 that is provided with on the axis, inclined-plane 4 of rocking bar 5 rotating shafts and fork 3 lower ends 18 is in a bit, the lower end 18 that so can prevent fork 3 drives slide bars 13 when doing straight reciprocating motion in guide pin bushing 11, and shake up and down takes place.Handle 10 is installed on the housing 1, is convenient to people's holds the utility model and operates.

Among Fig. 1,6 is the axle sleeve of

rocking bar

5, and 9 is the bonnet of

housing

1, and 8 is oil seal cover.

Rocking bar 5 and fork 3 contacted two faces also can be processed into sphere, and for example rocking bar 5 one sides are processed into concave spherical surface, and fork one side is processed into protruding sphere, the noise in the time of also can reducing wearing and tearing and work.

The course of work of the present utility model: the right-hand member of rocking bar 5 is packed into and is anchored on the pilot hole of drill bit, and under the drive that the electric drill motor shaft rotatablely moves, rocking bar 5 rotates.The other end of rocking bar 5 has an inclined-plane 4, makes fork 3 also be in obliquity.Because the both ends of the surface of fork 3 upper ends 17 flexibly connect by ball respectively and between the inclined-plane 4 of described rocking bar 5 other ends and the locking nut 2, and an end of the lower end 18 of fork 3 and slide bar 13 flexibly connects by roller 12, described roller 12 flexibly connects with slide bar 13, thus when rocking bar 5 rotates, promotion fork 3 upper ends 17 are attached at inclined-plane 4 and do the left and right directions swing, the lower end 18 of fork 3 drives slide bar 13 and do the left and right directions straight reciprocating motion in guide pin bushing 11, and the cutter that is installed in the chuck 14 is also done the left and right directions straight reciprocating motion.
