Specific embodiments

As shown in Figure 1, the garden tool 100 that the utility model disclosed can be used for mowing, topiary and other plant.This garden tool 100 comprises a main frame 1, and this main frame 1 can connect with different blade carrier, to realize different functions.As depicted in figs. 1 and 2, the short sword tool carrier 3 of having enumerated topiary rimmer knife tool carrier 2 in the present embodiment and having mowed.Each blade carrier all comprises base 4 and cutter, and topiary blade carrier 2 has the blade 20 of the do front and back straight reciprocating motion of a pair of length, and the blade carrier 3 of mowing has the blade 30 of the motion that swings of a pair of weak point.

As shown in Figure 3, the output that motor 10, one reducing gears are connected in motor 10 is housed in the main frame 1 of garden tool 100, is used to reduce the speed of motor 10.This reducing gear is a gear drive, comprises 4 gears 12,13,14,15.Wherein, gear 12 is installed on the output shaft of motor 10, and gear 13,14 is installed on the axle 16, and gear 15 is installed on the axle 11.Gear 12 and gear 13 are meshed, and gear 14 and gear 15 are meshed.The free end of axle 16,11 is conical, and both are parallel to each other, and the segment distance of being separated by in the vertical.These two axles 16,11 all stretch out from main frame 1, are connected with blade carrier.One eccentric is fixedly connected on the lower surface of gear 15, and this eccentric comprises large eccentricity wheel 17 and small eccentricity wheel 18, two eccentric wheels are made one.

Be the structure of example explanation garden tool 100 automatic tool presets below with topiary blade carrier 2.In Fig. 1, the main frame 1 of garden tool 100 is connected with topiary blade carrier 2, and the garden tool 100 of this moment can be used as a shrub trimmer and uses.As Fig. 1 and shown in Figure 5, two holes 21,22 of vertically arranging are arranged on the blade carrier 2, the spacing between these two holes equates with spacing between axle 16 and the axle 11, spools 16,11 can distinguish in the patchhole 21,22.The blade 20 of blade carrier 2 is made up of cutter 201 and bottom knife 202.Wherein, cutter 201 is a bending blade, and as shown in Figure 4, the bending that makes progress of the mounting portion of this blade 201 forms a dogleg section 205, cutting part 206 almost parallels of this dogleg section 205 and blade 201, and both are not in same plane; Bottom knife 202 is a flat blade.Preferably, last bottom knife 201,202 adopts and has certain flexible spring steel and make.In the present embodiment, last bottom knife 201,202 is done anti-phase straight reciprocating motion, and in other embodiments, this blade also can be made up of a movable blades and a stationary blade.The mounting portion of last bottom knife 201,202 has a big slotted eye 203 and a little slotted eye 204 respectively, the short radius of these two slotted eyes equates that with the radius of big or small eccentric wheel 17,18 on the axle 11 therefore big or small slotted eye 203,204 can match with big or small eccentric wheel 17,18 respectively respectively.Hole 22 is positioned at big or small slotted eye 203,204.Last bottom knife 201,202 is installed on the gripper shoe 5 of base 4 by bolt.This gripper shoe 5 is fixedlyed connected with base 4, and as shown in Figure 6 and Figure 7, gripper shoe 5 comprises a groove 50, and its size is greater than the mounting portion of bottom knife 202, so the mounting portion of bottom knife 202 is in vacant state.Cutter 201 is positioned on the bottom knife 202, and its dogleg section 205 also is in vacant state.Because last bottom knife 201,202 all has certain elasticity, so both in the vertical directions have freedom of motion, can be to bottom offset.

Also comprise back joint fastener 41 and left and right sides joint fastener 42,43 on the base 4 of blade carrier 2.Has a button 6 on the main frame 1.By this button 6, the user can handle connected hook 7 and turn to and cooperate with draw-in groove 44 on the base 4 or separate.When mounting cutter carrier 2, earlier in the hole 19 that back joint fastener 41 is inserted on the main frames 1, again axle 16,11 is aimed in the patchhole 21,22, press the button 6 this moment, makes hook 7 be in and produce the position, blade carrier of closing then 2 and main frame 1, make left and right sides joint fastener 42,43 engage with left and right sides groove 72,73 on the main frame 1, last release button 6, hook 7 changes in the groove 44, so blade carrier 2 is installed on the main frame 1.In this state, big or small eccentric wheel 17,18 might not just in time be positioned at big or small slotted eye 203,204, might be pressed on the edge of slotted eye, makes the mounting portion of going up bottom knife 201,202 move down.At this moment, starter motor 10, motor 10 drives big or small eccentric wheel 17,18 by reducing gear and rotates, when big or small eccentric wheel 17,18 turns to the short radius place of big or small slotted eye 203,204, can fall in the slotted eye 203,204, match, realize aiming at automatically with slotted eye.Simultaneously, last bottom knife 201,202 has not been owing to there has been the pressure of eccentric wheel 17,18, and pops up, and recovers reset condition.So blade 20 is done anti-phase straight reciprocating motion then under the drive of eccentric wheel 17,18, thereby implement to prune.

As shown in Figure 2, be example with the blade carrier 3 of mowing, blade 30 is made up of a movable blades 301 and a stationary blade 302, and movable blades 301 can swing with respect to stationary blade 302.Wherein, stationary blade 302 is fixedly mounted on the base 4; Movable blades 301 is the bending blade, and its dogleg section 305 can move by in the vertical direction.There is a slotted eye 303 mounting portion of movable blades 301, and it can match with the large eccentricity wheel 17 on the main frame 1.When needs used garden tool 100 as mower, the user can press the button 6, unloaded topiary blade carrier 2, changed the blade carrier 3 of mowing.The assembling process of blade carrier 3 is identical with the assembling process of above-mentioned blade carrier 2, earlier back joint fastener 41 is inserted in the groove 19 of main body 1, axle 16,11 is aimed in the patchhole 21,22 blade carrier 3 of closing respectively again.So blade carrier 3 is installed on the main frame 1.Under this confined state, eccentric wheel 17 is pressed on the edge of slotted eye 303 probably, and does not aim at, and makes the dogleg section 305 of movable blades 301 to bottom offset.At this moment, starter motor 10, eccentric wheel 17 is along with axle 11 rotations, when going to the short radius place of slotted eye 303, it falls in this slotted eye 303, realize aiming at automatically, the dogleg section 305 of movable blades 301 returns to initial conditions owing to leaving of eccentric wheel 17 pops up, and moves under the drive of eccentric wheel 17 then.For this blade carrier that a movable blades is only arranged, with the installation of main frame 1 and automatic tool preset the time, the small eccentricity wheel 18 on the axle 11 is in idle state.

Those of ordinary skill in the art should expect easily that the blade carrier with other cutters also can be installed on the main frame, thereby can be so that this garden tool has purposes widely.As long as comprise the function that at least one blade that has bending can be realized automatic tool preset in its cutter, for user's tool changing provides convenience.

The garden tool that the utility model discloses is not limited to content mentioned above and structure shown in the drawings.For example, the material of cutter is not limited to spring steel, also can adopt other suitable to have certain flexible material; Mounting structure between blade carrier and the main frame; Eccentric number when the cutter on the blade carrier all has only a movable blades, only needs an eccentric wheel can realize automatic tool preset.In a word, on basis of the present utility model, the shape of other members and position made apparently and change, substitute or revise, all within scope of the present utility model.
