Abstract

The utility model discloses a grass cutter rotating mechanism for grass trimmer, which comprises a hand grip, a handle and a grass cutter which is positioned inside the inner annular slot of the handle top terminal movably. A limit gear I and a limit gear II are arranged on the inner annular slot. A limit rotating block I which rotates 90 degrees correspondingly with limit gear I, and a limit rotating block II which rotates 90 degrees correspondingly with limit gear II, are positioned at the grass cutter. With the effect of the limit gears and limit rotating block, the grass trimmer can achieve two models of normal grass trim and edge-cutting grass trim, by operating the pressure block positioned on the grass trimmer handle, which can drive a connected lock block on the pressure block to lock the two gearshifts located on the grass cutter moveably. The edge-cutting grass trim model can trim grasses at corner effectively. The utility model has improved structure and better practicability and can meet the market demand well.

Description

Rotary mechanism of moving head of grass machine

Technical field

The utility model relates to mower, the especially rotating mechanism of mower moving head on finishing in a kind of flower bed, lawn, the garden, cutting meadow.

Background technology

The handle and the moving head of existing mower all are disjunctors, handle is provided with starting switch, be provided with micro-machine in the moving head, the rope of fixedly beating the grass on the motor output shaft, starter motor work, the drive rope high speed rotating of beating the grass can carry out the finishing and the cutting on meadow, because the moving head that is connected handle end can't rotate, therefore often can't effectively cut off for the weeds that are grown in the inside, little corner.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art and provides a kind of to need the rotation moving head can reach that routine is beaten the grass and the rotary mechanism of moving head of grass machine of the two states of beating the grass is cut on the limit, can effectively cut off the weeds of the inside, little corner by this mechanism.

Technical problem of the present utility model is achieved through the following technical solutions:

A kind of rotary mechanism of moving head of grass machine, comprise handle, handle and moving head, it is characterized in that described moving head is rotatably installed on the inner groove of handle bottom, inner groove is provided with spacing shelves I and spacing shelves II, is provided with the rotating limit block I of 90 ° of relative limit shelves I rotations and the rotating limit block II that relative limit shelves II rotates 90 ° simultaneously on moving head; Also be provided with the button that is subjected to spring push on the described handle, button is provided with the disjunctor fixture block, and moving head is provided with two the gear a and the gear b that are subjected to the movable locking of disjunctor fixture block.

Described handle is formed by the mutual snapping of two and half shells.

Compared with prior art, the utility model is rotatably installed in moving head on the inner groove of mower handle end, inner groove is provided with spacing shelves I9 and spacing shelves II10, on moving head 7, be provided with simultaneously the rotating limit block I11 of 90 ° of relative limit shelves I rotations and the rotating limit block II12 that relative limit shelves II rotates 90 °, by two gears on the movable locking of disjunctor fixture block set on mower handle moving head, make this mower reach the purpose that routine is beaten the grass and the two states of beating the grass is cut on the limit, the weeds that the state of beating the grass can effectively cut off the inside, little corner are cut on the limit, this structure operation is simple, have better practicality, fully meet the need of market.

Embodiment

To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.

As Fig. 1～shown in Figure 7,1-handle, 2-switch, 3-power line, 4-handle, 5-button, 6-spring, 7-moving head, 8-disjunctor fixture block, the spacing shelves of the spacing shelves of 9-I, 10-II, 11-rotating limit block I, 12-rotating limit block II, 13-gear a, 14-gear b.

Rotary mechanism of moving head of grass machine can be connected on the mini mower of plastics system handle or metal system handle, realizes that routine is beaten the grass and the two states of beating the grass is cut on the limit.Its structure comprises " L " type handle 4 that is formed by the mutual snapping of two and half shells, this half shell structure such as Fig. 3～shown in Figure 5, handle top also is connected with handle 1 simultaneously, handle is provided with switch 2 and power line 3, hide the lead that connects switch in the handle, one inner groove structure is arranged at handle 4 bottoms, this inner groove is provided with spacing shelves I9 and spacing shelves II10, two position of bone lay respectively on the inner groove of two and half shells, spacing shelves I9 can play the anti-forward rotation when routine is beaten the grass state, spacing shelves II10 can play the anti-reverse rotation of cutting on the limit when beating the grass state, simultaneously also be provided with opening at " L " of handle 4 type turning, opening part is provided with by spring 6 pushing tows can pass the up and down button of opening 5, and button is provided with disjunctor fixture block 8.

Moving head 7 rotates and is fitted in handle 4 bottoms, be provided with micro-machine (not shown) in it as power source, moving head such as Fig. 6, shown in Figure 7, fix one on it and rotate equipped rotating disk with handle 4 inner grooves, this rotating disk simultaneously is provided with two relative limit shelves I9 and rotates the rotating limit block II12 that 90 ° rotating limit block I11 and relative limit shelves II10 rotate 90 °; Another side is provided with two the gear a13 and the gear b14 that are subjected to the disjunctor fixture block 8 movable lockings on the button 5.Gear a is the routine state position of beating the grass, and its effect is when guaranteeing that disjunctor fixture block 8 is in this latched position, and mower is in the routine state of beating the grass; Gear b is that the state position of beating the grass is cut on the limit, and its effect is that mower is in the limit and cuts the state of beating the grass when guaranteeing that disjunctor fixture block 8 is in this latched position.

The conversion of beating the grass of the utility model two states is very convenient, when being in routine and beating the grass state, the limited shelves of rotating limit block I11 I9 blocks, make whole moving head 7 to turn clockwise, disjunctor fixture block 8 on the button 5 also locks gear a13 simultaneously simultaneously, makes whole moving head also can't be rotated counterclockwise; When making mower adjust to the limit from the routine state of beating the grass, cut when beating the grass state by needs, pressing keys 5 makes it overcome spring 6 elastic force and down moves, disjunctor fixture block 8 on the button promptly staggers with gear a13 at this moment, the moving head rotation, because the limited shelves of the clockwise direction of rotating limit block I12 I9 blocks, therefore moving head 7 can only be rotated counterclockwise, when forwarding the limited shelves of rotating limit block II12 II10 to and block, moving head just goes to 90 °, decontrol button 5 this moment, button rises under spring 6 elastic force effects and resets, thereby drives the disjunctor fixture block 8 locking gear b14 on the button, and moving head 7 promptly is lockable and can't turns clockwise.Promptly enter the limit and cut the state of beating the grass this moment, and the weeds in the little corner are effectively cut off.
