Embodiment

For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.

The utility model is a kind of extirpator, as Fig. 1, Fig. 2, Fig. 4, Fig. 5, shown in Fig. 6, it comprises extirpator main body 2, extirpator main body 2 is the metal pipe that a hollow bending 90 is spent, one end of extirpator main body 2 is the handle of extirpator, handle jacket is sleeve 1 on the other hand, the solder joint 6 of the other end of extirpator main body 2 and pedal 5 welds, in pedal 5, have a foot-operated plate hole 14, the 90 degree places in extirpator main body 2 open a kerf 7, its inner side is molded into a circular arc 8 through pushing in backward, there is a push rod 9 through in the extirpator main body 2 of otch 7, the upper end of push rod 9 connects push-pull button 10, there is the second butterfly limit 19 of an extrusion modling at the nearly middle part of push rod 9, one first pad 20 is being worn on the top on the second butterfly limit 19, the first pad 20 tops are installed with a spring 21, be installed with one second pad 22 at otch 7 places near extirpator main body 2, the lower end of push rod 9 is squeezed into the first butterfly limit 12, through foot-operated plate hole 14 and board butterfly lateral opening 13, solder joint 11 in push rod 9 ends, lower end welds slide block 4, on slide block 4, evenly have multiple slide block pawl nails hole 15, and align with board pawl nail hole 16, but the central diameter in slide block pawl nail hole 15 is more smaller than the central diameter in board pawl nail hole 16, in board pawl nail hole 16 and slide block pawl nail hole 15, be installed with pawl nail 3, pawl is followed closely 3 surfaces straightedge 24 (as shown in Figure 8), board 17 connects by screw 18 with pedal 5.

As shown in Figure 2, for the structural representation of extirpator assembling section inside, this figure is also that extirpator is under the thrust of spring 21, push rod 9 moves downward, until push rod step 23 (as shown in Figure 7) gear stops to board face 25, pawl is followed closely 3 these time delay slider bore 15 and is opened, and is split into extirpator readiness for operation.

As shown in Figure 3, for careless schematic diagram is grabbed in extirpator work, namely extirpator operator holds taper knob 1 place of extirpator, pawl nail 3 is aimed on the weeds that will pull out, tramp with one's feet and step on sole 5, under the effect of pedal force, pawl nail 3 gos deep in weeds earth around, earth promotes slide block 4 and is slided along board butterfly lateral opening 13 in the first butterfly limit 12 of push rod 9, because align with board pawl nail hole 16 in slide block pawl nail hole 15, but the central diameter in slide block pawl nail hole 15 is more smaller than the central diameter in board pawl nail hole 16, so pawl nail 3 has formed Five-link machine with slide block pawl nail hole 15, pawl is followed closely 3 inward collapsibles, together with the earth of weeds and weeds root, catch, push-pull button 10 is held in operator's one have gentle hands, mention extirpator simultaneously together with another hand, the main root of weeds is firmly held and is pulled up by pawl nail 3 with earth together, when handgrip push-pull button 10 is decontroled, push rod 9 is at the first pad 20, spring 21, under the effect of the second pad 22, move downward, push rod 9 is with movable slider 4 to move together, pawl nail 3 is outwards launched, at this moment by the pawl nail 3 weeds roots of holding tightly and earth along with the promotion 9 of slide block 4 and the outside expansion of pawl nail 3, weeds drop from the pawl nail 3 of extirpator together with root.

Board butterfly lateral opening 13 coordinates with the first butterfly limit 12 of push rod 9 heads, is guarantee the location of push rod 9 and only have a degree of freedom sliding up and down the rotation of restriction push rod 9.

Straightedge 24 design that pawl is followed closely 3 surfaces is the friction in order to reduce the slide block pawl nail hole 15 on pawl nail 3 and slide block 4, thereby can reduce the manufactured materials of spring 21, reduces costs, weight reduction.
