The support rods 110 are formed into a long pipe shape. At this time, the support rod 110 is a member which influences the overall length of the weed-removing tongue 100 and extends to have a predetermined length along the front-rear direction so as to remove weeds from a long distance. The inside of the support rod 110 is empty, and a grip unit 130 is installed at the front end and a grip 120 is installed at the rear end. The support rod 110 is preferably made of a metal having high durability, and it is most preferable that the support rod 110 is made of aluminum. Although not shown in detail in the present embodiment, the support rod 110 may have a telescopic structure for the convenience of storage and movement, and may be configured to be elongated or reduced in length.

The handle 120 is provided at the rear end of the support rod 110. The handle 120 is rotatably coupled with the support rod 110 wrapped around the handle 120. The grip portion 120 is rotatably moved in both left and right directions and the grip unit 130 is operated in accordance with the rotation of the grip portion 120. [ The grip 120 serves as a grip gripped by the operator. For this purpose, a grip (not shown) for providing a buffering force and a frictional force such as rubber or silicon may be coupled to the outer surface of the grip 120.

The clamp unit 130 is provided at the front end of the support rod 110. The grip unit 130 is operated by the gripper driving unit 140 driven when the grip part 120 is rotated so that the two grippers 132 and 134 are opened or closed. The grip unit 130 includes a fixed grip 132 fixed to the front end of the grip rod 110 and a pivot gripper 132 rotatably coupled to the front end of the grip rod 110, 134 and an elastic member 136 for providing an elastic force to the pivoting pivot 134 to pivot the pivoting pivot 134 to cause the pivoting pivot 134 and the fixed pivot 132 to open.

One end of the fixed clamp 132 is fixed to one side of both sides of the front end of the support rod 110. The fixed gripper 132 has a curved shape and a gripping plate 138 protruding from the other end is coupled. The pivot pin 134 has a curved shape and is provided at one end of the front end of the pivot rod 110 so as to face the fixed pintle 132 at one end. The pivot pin 134 is rotatably coupled about the pivot shaft 133 and is provided with an elastic force from the elastic member 136 through the push portion 135. A gripping plate 138 protruding like a fixed grip 132 is coupled to the other end of the rotating gripper 134. The gripping plate 138 of the fixed gripper 132 and the gripping plate 138 of the swing gripper 134 are closely contacted with each other in accordance with the rotation of the swing gripper 134 and used for catching weeds. The elastic member 136 provides an elastic force to the pivoting tongue 134 to pivot the pivoting tongue 134. Both end portions of the elastic member 136 are fixed to the pressing portion 135 of the pivoting tongue 134 and the inside of the holding bar 110, respectively. The elastic member 110 may be a coil spring or a leaf spring as an elastic body that provides a tensile elastic force. The swinging gripper 134 rotates about the swing shaft 133 by the elastic force of the elastic member 136 so that the gripping plate 138 of the swinging gripper 134 and the gripping plate 134 of the holding gripper 132 rotate, (138).

The pivoting of the pivoting forceps 134 is determined by the elastic member 136 and the force of the pivoting force of the pivoting forceps 134, Unit 140 as shown in FIG.

In addition, the gripping plate 138 can be joined at an angle from the fixed gripper 132 and the pivoting gripper 134, as shown in FIG. Specifically, the fixed clamp 132 and the pivoting clamp 134 extend along the longitudinal direction of the support rod 110. At this time, the length of the gripping plate 138 is not located on the extension line of the fixed gripper 132 and the pivoting gripper 134, but the length of the gripping gripper 132 and the pivoting gripper 134 is set at a predetermined angle a). It is preferable that the angle a between the fixed clamp 132 and the pivot plate 134 and the longitudinal direction of the grip plate 138 is approximately 40 to 45 degrees. When the gripping plate 138 is slantingly engaged with the fixed gripper 132 and the turning gripper 134 in the longitudinal direction as described above, the gripping plate 138 is horizontally It has the advantage of being able to catch weeds more easily and firmly because it is maintained.

Referring again to FIGS. 1 to 3, the gripper drive unit 140 is rotated by the elastic member 136 between the fixed gripper 132 and the swing gripper 134, And controls the rotation of the pivoting tongue 134 so that the gap is re-opened in a state where the pliers 134 are clogged. The forceps drive unit 140 includes a drive screw 142 that rotates together with the handle 120 in the handle 120 and a drive screw 142 that surrounds the drive screw 142 and moves back and forth A moving member 144, and a wire 146 to which both ends are connected to the moving member 144 and the grip unit 130, respectively.

The driving screw 142 is threaded outward and connected to the inside of the handle 120 to rotate together with the handle 120 when the handle 120 rotates. The moving member 144 is passed through the driving screw 142 and moves forward or backward along the inside of the support rod 110 when the driving screw 142 rotates in the forward and reverse directions. To this end, the shifting member 144 may be mated and coupled to the inside of the strut 110. One end of the wire 146 is connected to the moving member 144 and the other end is connected to the pressing portion 135 of the pivoting tongue 134. The wire 146 has a predetermined thickness and is flexible and has a rigidity higher than a certain level.

Hereinafter, the operation of the weed-removing tongs according to one embodiment of the present invention will be described in detail.

3, when the handle 120 is rotated in the normal direction, the drive screw 142 rotates together with the handle 120 and the movable member 144 is rotated by the rotation of the drive screw 142, And the wire 146 are moved forward. On the other hand, the pivoting tongue 134 is rotated around the pivoting shaft 133 by the advance of the wire 146 and the elastic force of the elastic member 136, so that the pivoting tongue 134 is separated from the fixed tongue 132 as shown in Fig.

The weed that is to be pulled out is brought into contact with the fixed gripper 132 in a state where the fixed gripper 132 and the pivot gripper 134 are separated from each other and then the handle 120 is turned in the opposite direction. The driving screw 142 rotates reversely with the rotation of the knob 120 and the moving member 144 and the wire 146 are moved backward by the rotation of the driving screw 142. [ The pressing portion 135 of the rotating tongue 134 to which the other end of the wire 146 is connected is pulled in accordance with the backward movement of the wire 146 and the rotating tongue 134 is rotated around the rotating shaft 133 And the weights are pressed between the fixed clamp 132 and the grip plate 138. When the weeds are fixed between the two tongs 132 and 134 by the above process, the struts 110 are lifted or pulled to remove the weeds from the ground.

The weed removing tongue 100 according to the present invention can be easily removed from a remote place by using two tongs 132 and 134 which are separated or opened by the pivoting of the pillar 110 and the handle 120 having a predetermined length There is an advantage that weeds can be easily and simply removed by turning the handle 120 only.

The fixed tongue 132 is fixed to the tie rod 110 and only the tongue 134 is rotated from the tie rod 110 to bring the weighed tongue to be drawn into the fixed tongue 132, So that the weeds can be gripped more firmly without being twisted.
