The utility model solves the defect existed in background technology, and the utility model possesses following beneficial effect:
(1) by the action of toggle mechanism, driven wheel can be shifted one's position between the first gear and the second gear, serve the effect of conversion driven wheel engagement object, simultaneously because the first gear is contrary with the second gear direction of rotation, ensure that each driven wheel conversion engagement object rear drive shaft all converts direction of rotation.
(2) direction of rotation of driving shaft and the direction of stirring of toggle mechanism form linkage structure just, when driven wheel and the first gears meshing, toggle mechanism driven shaft drives the tendency and power that toggle mechanism are had driven wheel is allocated to the second gear, and final driven wheel departs from the first gear, and the elastic potential energy of the first spring on fork is relied on to drive and the second gears meshing; Otherwise when driven wheel and the second gears meshing, toggle mechanism can make driven wheel counter motion.
(3) structure of feather key can ensure that the clip existed between driven wheel and driving shaft along driving shaft circumference limits on the one hand, ensure driven wheel can not circumferentially with driving shaft generation relative motion, on the other hand driven wheel can sliding axially along driving shaft, ensures that driven wheel moves between the first gear and the second gear.
(4) two shifting fork bars lay respectively at driven wheel both sides, driven wheel can driving lever drive under, along driving shaft axially-movable.
(5) athletic posture that block can limit driving lever is overlapped, the fork that first spring drives can be limited in certain hunting range by block simultaneously, and then the range of movement of driving lever is also defined, ensure the left and right skew that driving lever can not be excessive, only ensure that driven wheel converts the spacing of engagement between the first gear and the second gear.
(6) when driven wheel and the first gears meshing, fork offsets towards the first gear side, now the first spring straining fork, swivel nut by screw drive away from the first gear, then first the first tightrope is tauted, and then pull fork to rotate towards the second gear side, when fork crosses vertical state, driven wheel and the first gear depart from, now fork just can pull and support towards the second gear side by the pulling force of the first spring, and fork is swung towards the second gear direction, driven wheel presses and the second gears meshing the most at last.
(7) shifting fork bar is constantly moved left and right along driving shaft by two shifting fork bars promotion driven wheels in the side-to-side movement process of driving lever, change engagement object.
Cooperatively interacting of (8) first rotating shafts and the second rotating shaft, makes fork with the second rotating shaft for rotating in the center of circle, to drive driving lever to move left and right, and then shift fork bar is followed driving lever and moved left and right.
(9) two pulleys are arranged on the left and right sides of the second rotating shaft, and the second tightrope is by after the company's of walking around pulley, and the second tightrope of transformation pulls the direction of fork, ensures that two tightropes can pull fork respectively from different directions.
(10) move left and right in process at knee, the first tightrope and the second tightrope can realize nonsynchronous preferential tensioned state, fork is achieved situation that the same time only can be tightened by a tightrope.
(11) arranging of block ensures that the lower end of fork can not be departed from and overruns, and also namely fork can not make driving lever moving range excessive.
(12) structure of screw drive swivel nut, and then swivel nut provides power resources for toggle mechanism, because the rotation direction of screw rod is relevant with the object that driven wheel engages, so, the direction of motion of swivel nut is relevant with the rotation direction of driving shaft, and the rotation direction of driving shaft is subject to the control of toggle mechanism; Such said process just forms interactional cyclic motion process, and toggle mechanism and driving mechanism constantly affect continuous loop control.
(13) when driven wheel and the first gears meshing, rolling wheel near the second gear side just tightens up the tightrope of its correspondence, after tightrope is tightened to certain energy degree, fork just pulls by tightrope, shifting fork bar motion now on driving lever, driven wheel promotes to the second gear direction by shifting fork bar, and finally makes driven wheel and the second gears meshing, and driving shaft is reversed; Otherwise driven wheel is pulled to the first gear direction and engages.
Spacing between (14) two shifting fork bars is greater than the axial length of driven wheel, provides heterodromous inertia to cushion can to the motion of driven wheel.
Spacing between (15) two shifting fork bars is greater than the axial length of driven wheel, the length of being longer than driven wheel is the length surpluses of two shifting fork bar spacing relative to driven wheel, due to the existence of above-mentioned surplus, fork is when being in vertical state, two shifting fork bars all can not stop by driven wheel, only need when fork crosses its vertical state to rely on inertia.
(16) travelling gear is coaxial with the first gear, and the second gear engages with travelling gear, achieves the reverse rotation of the first gear and the second gear.
(17) locking lever on shut-down mechanism can pull up by handle, and being stopped the projection that the right-angle surface in mechanism blocks like this can depart from constraint, and driving lever just can continue to move left and right, only otherwise pulling up mechanism just only can do monocyclic motion.
(18) projection can be blocked in the position of driven wheel just between the first gear and the second gear by the position that shut-down mechanism is arranged, and now driven wheel departs from engagement.
(19) by the gearing of driving mechanism, the object power of motor being transported to drill bit is achieved; Simultaneously by the effect of toggle mechanism, the engagement object of driven wheel can be converted, so realize drill bit and retrogressing complete after stopping.
