Description
Technical field
The utility model relates to a kind of governor motion of graden machine, specifically is the angle regulation positioning device of pruner.
Background technology
Pruner is a kind of graden machine of routine, is used for repairing the tree-like of trees, shrub, needs the two hand-held sets of operating personnel to carry out operation.Its basic structure is to utilize the motion of motor to drive two movable tooth rows to carry out linear reciprocating motion, because the direction of motion of two movable tooth rows is opposite, and movable tooth row dual-side is along the basic vertical and direction of motion of the knife edge of the some serrated knives that stretch out, will shear branch or the blade of trees, shrub by the formed shearing motion of the relative motion of serrated knife, so that trees, shrub tree-like reaches desirable effect.Existing pruner is simple in structure, is to fixedly connected between its handgrip and the host machine casing, can not adjusting angle; When the tree-like pruning operation of carrying out multiple angles, operating personnel need the multiple machine angle of holding of frequent conversion, and not only workload is big, and efficiency is not high yet.
The utility model content
Technical problem to be solved in the utility model provides a kind of long handle pruner main frame dividing and positioning mechanism, this mechanism should be able to overcome the deficiency of above-mentioned background technology, can regulate the angle between pruner main frame and the handgrip as required, have regulate flexibly, reliable operation, characteristic of simple structure.
The technical scheme that the utility model provides is: long handle pruner main frame dividing and positioning mechanism, comprise host machine casing and annular handgrip, the both sides of described host machine casing respectively are shaped on the internal spur gear that a coaxial line is arranged, and respectively have a gear that is meshed to be positioned at respectively in the described internal gear; The corresponding cavity that a both sides is shaped on respectively of described annular handgrip surrounds aforesaid internal spur gear and gear; Also respectively be shaped in each cavity one can with the internal gear of gears engaged, the be placed in outside of internal spur gear and keep certain axial spacing of this internal gear with internal spur gear; The facewidth of described gear is less than the facewidth of internal spur gear, and each gear is subjected to the axial compressive force of the direction laterally that some springs apply respectively, make each gear simultaneously and internal spur gear and internal gear engagement so that the angle of locking host machine casing and annular handgrip; The both sides of annular handgrip also are shaped on a through hole respectively, this through hole is positioned at the axial end and the through hole location one division of gear and presses head, the axial end application of force of gear is made move in it and the engagement of disengaging and internal gear so that the pressing calibration is pressed head, reach the purpose of adjusting host machine casing and annular handgrip orientation angle.
Be shaped on respectively on the axial end of described each gear and the relevant position on the casing and be suitable for the blind hole that spring inserts the location.
Be shaped at least six internal tooths on the described internal gear.
Use of the present utility model is very simple: the operator only needs press head with the calibration of pointing roof pressure host machine casing both sides simultaneously, its chain promotion gear is moved and the engagement of disengaging and internal gear, and host machine casing promptly is in the state of relatively rotating with annular handgrip; As long as the requirement of the angle match operation person after rotating between host machine casing and the annular handgrip, can remove the pressing power of calibration being pressed head, spring force it is moved laterally and once more with the internal gear engagement, locked the relative position between host machine casing and the annular handgrip thus; Angular adjustment is promptly finished.
The beneficial effect that the utility model produces is: owing to can regulate angle between host machine casing and the annular handgrip easily and flexibly, thereby the working strength of operating personnel when operation reduce relatively, and efficiency is improved.In addition, because design is ingenious, so structure is also simple, the reliability of mechanism's work is higher.

Embodiment
As shown in Figure 1, long handle pruner main frame dividing and positioning mechanism, comprise host machine casing 10 and annular handgrip 8, the internal spur gear 15 that each side is shaped on a coaxial line layout of described host machine casing, and respectively have a gear that is meshed 3 to be positioned at respectively in the described internal gear; The left and right sides of described annular handgrip then is shaped on corresponding cavity respectively aforesaid internal spur gear and gear is surrounded; Also respectively be shaped in each cavity one can with the internal gear 16 of gear 3 engagement, the be placed in outside of internal spur gear and keep certain axial spacing of this internal gear with internal spur gear; Among Fig. 4, Fig. 5 as can be known: close up and with some screws (by screw base 3-3) connection that is tightened by handgrip upper casing 8-1 and handgrip lower casing 8-2, on handgrip upper casing 8-1 and the handgrip lower casing 8-2 edge one circle nib 8-5 just in time embeds a circle groove of the left and right sides of host machine casing, can keep relatively rotating of annular handgrip and host machine casing like this, cavity is effectively isolated with extraneous.Described internal gear 16 can be that the number of teeth is complete, also can only use several teeth; As can be known, each internal gear 16 is spliced by handgrip upper casing 8-1 and handgrip lower casing 8-2 among Fig. 4, Fig. 5; Wherein only make three internal tooths (quantity of the number of teeth can increase and decrease as required) respectively on handgrip upper casing 8-1 and the handgrip lower casing 8-2, can carry out work effectively.
In addition, the facewidth of described gear is less than the facewidth of internal spur gear, and each gear is subjected to the axial compressive force of the direction laterally that some springs 4 apply respectively, make each gear simultaneously and internal spur gear and internal gear engagement so that the angle of locking host machine casing and annular handgrip; Among Fig. 4, Fig. 5 as can be known: each gear all is subjected to the pressure of three springs 4, and is shaped on respectively on the axial end of each gear and the relevant position on the casing and is suitable for the blind hole that spring 4 inserts the location; So when the inside pressing gear of the application of force, spring 4 is forced to shrink, and gear 3 can slip in (sinking to) internal spur gear 15 fully.
The both sides of annular handgrip also are shaped on a through hole respectively, this through hole is positioned at the axial end of gear and through hole location one division and presses 1, the axial end application of force of gear is made move in it and the engagement of disengaging and internal gear so that the pressing calibration is pressed head, reach the purpose of adjusting host machine casing and annular handgrip orientation angle.Among Fig. 4, Fig. 5 as can be known: this through hole is spliced by handgrip upper casing 8-1 and handgrip lower casing 8-2; Calibration is pressed 1 inside (being parallel to pivot center 20 directions) and is shaped on four sheets that overhang, and wherein is shaped on to the outstanding bead of periphery direction on two sheet 1-1 that overhang, and then is shaped on the through hole to the outstanding convex of pivot center 20 directions; This bead is caught on by convex, can guarantee that calibration presses head and be positioned at (can not break away from through hole) in the through hole.Calibration is pressed the axial end that other two sheet 1-2 that overhang on 1 then directly extend to gear; So, the operator is when pressing head (two calibration that only need be positioned at the host machine casing both sides with the finger while pressing of one hand are pressed head) with finger pressing calibration, just but two gears of roof pressure move and the engagement of disengaging and internal gear to internal spur gear, make host machine casing and annular handgrip be in rotatable state, so that the operator selects needed angle.
