Embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described.

As accompanying drawing 1,2 illustrate: a kind of extirpator, it comprises handle 1, support tube 2, pullover 101, uprooting weed jaw 5, described handle 1 comprises outdoor handle 11 that is connected with the upper end of described support tube 2 and the inner handle 12 that is provided with rotationally with described outdoor handle 11, the lower end of described support tube 2 is connected with described pullover 101, the upper end of described uprooting weed jaw 5 is accommodated in described pullover 101, being provided with in described support tube 2 can be along the connecting rod 4 of support tube 2 length directions slip, the upper end of described connecting rod 4 is connected with described inner handle 12, and the lower end of described connecting rod 4 is connected with the upper end of described uprooting weed jaw 5.

Described uprooting weed jaw 5 roughly takes the shape of the letter U, and its U-shaped structure has elasticity, and two arms of U-shaped structure can open relatively under the situation that is subjected to the external force effect or be close.

Be provided with first locating part 6 in described support tube 2, be provided with spring 7 between first locating part 6 and uprooting weed jaw 5, described spring 7 is set on the described connecting rod 4.

As 5,6 signals of accompanying drawing: on described outdoor handle 11, offer through hole 8, be connected with second locating part 9 on the described inner handle 12, described second locating part 9 is in the downside of through hole 8, described downside refers to when using extirpator, side near ground, the length of described second locating part 9 is less than the length of through hole 8 and greater than the width of through hole 8, the width of described second locating part 9 is less than the width of through hole 8.Described outdoor handle 11 is provided with the 3rd locating part 13 that is used to limit described second locating part 11 positions, described the 3rd locating part 13 is positioned at the infraoral outside of through hole 8, described the 3rd locating part 13 has two, and they lay respectively at the both sides of described through hole 8 and being staggeredly located out in the horizontal direction.

Exert pressure earthward for convenience, support tube 2 is provided with the foot-operated stressed member 3 that is used to ride.

In order to reduce the friction between uprooting weed jaw 5 and pullover 101, described pullover 101 is provided with friction and slows down part 10, described friction slows down part 10 and comprises the roller bearing 102 that is arranged on described pullover 101 both sides rotationally, described roller bearing 102 is connected by roller bearing pin 103 phase pivots with described pullover 101, and described uprooting weed jaw 5 is inconsistent with described roller bearing 102.

In use, at first with inner handle 12 relatively and outdoor handle 11 be that turning cylinder rotates to the state shown in the accompanying drawing 6 with the axial line of connecting rod 4, because the length of second locating part 9 is greater than the width of through hole 8, so second locating part 9 and described outdoor handle 11 are inconsistent and block, make inner handle 12 and outdoor handle 11 in the position of vertical direction by relative fixed, at this moment, aligning target to be pulled out, hand-held outdoor handle 11, firmly the uprooting weed jaw 5 with the extirpator front end inserts in the soil, during insertion, can tramp with one's feet that stressed member 3 is stepped in step so that uprooting weed jaw 5 gos deep into soil.After uprooting weed jaw 5 enters in the soil fully, one hand or both hands hold outdoor handle 11, outdoor handle 11 is rotated repeatedly to drive uprooting weed jaw 5 rotation repeatedly, this moment, the root of weeds or seedling separated with soil under the effect of fork fully, then, initial position (being attached position illustrated in Figure 5) is returned in inner handle 12 reverse rotations, because the length of second locating part 9 and width are respectively less than the length and the width of through hole 8, so at this moment second locating part 9 can slip in the through hole 8, that is to say that inner handle 12 can slide with respect to outdoor handle 11 in the vertical directions, at this moment, upwards spur inner handle 12 to the position shown in the accompanying drawing 4, weeds or seedling that uprooting weed jaw 5 and uprooting weed jaw 5 are clamped also can upwards be risen, thereby reach the purpose of uprooting weed, and the top of uprooting weed this moment jaw 5 has entered in pullover 101.And in the process that becomes by the state shown in the accompanying drawing 3 by the state shown in the accompanying drawing 4, the top of uprooting weed jaw 5 and roller bearing 102 are inconsistent, roller bearing 102 is close to the outer surface of uprooting weed jaw 5 and is rotated around roller bearing pin 103, can reduce the friction between uprooting weed jaw 5 and pullover 101 like this, make that to lift inner handle 12 convenient and strength-saving.

In the described in the above process that is pulled upwardly inner handle 12, uprooting weed jaw 5 also upwards rises, the upper end of the spring 7 between the uprooting weed jaw 5 and first locating part 6 and described first locating part 6 are inconsistent, the lower end of spring 7 is subjected to upwarding pressure of uprooting weed jaw 5 and is compressed, after weeds are extracted, unclamp inner handle 12, the elastic force of spring 7 makes uprooting weed jaw 5 move downward, and returns to initial position.

The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
