Multi-joint shifting slide gear 61 connects, and shifting block 7 other end forms lasso 72 being set on guide pillar 8 makes the shifting block 7 can be along leading
Post 8 moves, and the setting direction of guide pillar 8 is parallel with slip shaft 62 simultaneously.It is provided with pin on the outer face of above-mentioned lasso 72
Axle 73, one end of driving lever 2 is connected with swing arm 10 and offers U-lag 21 on the other end, and this bearing pin 73 is flush-mounted in U
In shape groove 21 so that shifting block 7 is formed with driving lever 2 and is connected.So drive lower rotation, swing arm when swing arm 10 knob 5 again
10 drive driving lever 2, and driving lever 2 makes lasso 72 move along guide pillar 8 further through bearing pin 73, so that shifting block 7 drives many
Connection shifting slide gear 61 moves along slip shaft 62.
In the present embodiment, knob 5 includes operation dish 51 and is arranged at the chassis 52 below operation dish 51, this operation dish
The bottom surface of 51 and the end face on chassis 52 form the most sliding distribution structure, i.e. this cunning distribution structure and include bottom surface and the end of operation dish 51
The end face of dish 52.In the present embodiment, the bottom surface of operation dish 51 is provided with elastic steel ball 54 and spacer pin 55, and the end
The location hole group snapped in for this elastic steel ball 54 and the stopper slot embedded for spacer pin 55 is offered on the end face of dish 52
522.Location hole group is made up of hole 521, two location, this hole 521, two location distribution spacing on this end face and speed change
In gear train 9, the spacing of two change-speed gearings 91 is corresponding, i.e. when operation dish 51 rotates relative to chassis 52, elastic
Steel ball 54 is deviate to slide at chassis 52 end face with operation dish 51, when knob 5 rotates in hole 521, a location from which
To the angle needed, elastic steel ball 54 snaps in again in another hole 521, location, thus realizes location, it is ensured that boring machine
The accuracy of speed change.Above-mentioned stopper slot 522 extends along the spacer pin 55 glide direction on this end face and its length and change
Speed gear train 9 length match, so when knob 5 rotates, spacer pin 55 with operating portion in stopper slot 522
Slide, be prevented effectively from multi-joint shifting slide gear 61 and exceed stroke.
Above-mentioned swing arm 10 the most axially wears operation dish 51 and the center on chassis 52 of knob 5, and driving lever 2 radially connects
It is connected to the end of swing arm 10, and the end of driving lever 2 is formed for the jack 22 that swing arm 10 end is inserted, swing arm 10
It is arranged with two buckle projections 101 on outer peripheral face up and down, and distinguishes on the hole wall of operation dish 51 centre bore 53 and jack 22
Offer the snap-fit grooves 531 snapped in for each buckle projection 101.
As fully visible, when rotating clockwise or counterclockwise knob 5, swing arm 10 drives driving lever 2, driving lever 2 front end
U-lag 21 drives again bearing pin 73 so that lasso 72 moves along guide pillar 8, and then makes the fork 71 of shifting block 7 drive many
Connection shifting slide gear 61 horizontally slips along slip shaft 62, makes multi-joint shifting slide gear 61 nibble from the change-speed gearing 91 of the different numbers of teeth
Closing, it is achieved the fast of variable-speed shaft 3 converts at a slow speed, variable-speed shaft 3 drives to again main shaft 1, and then makes the fast of main shaft 1 become at a slow speed
Change, finally realize the conversion of boring machine drilling speed.
