. The support part 140 includes a support piece to allow the operation rod to be penetrated and link pieces 141 and 142 formed to be bent at a right angle at opposite edge ends of the support piece. The tongs part 150 is hinged-coupled with the link pieces 141 and 142 and an intermediate portion of the support part 140, and is bent in a ‘’ shape. The tongs part 150 is comprised of operation parts 153 provided at one side thereof and upper and lower tongs parts 152 and 151 provided at the other side thereof. Each of the lower tongs parts 151 has a saw-toothed shape at opposite side surfaces of an end thereof, thereby picking up chestnut burrs. The fixed lever 163 is fixed, at one end thereof, to an outer peripheral surface of one side of the body 111 while being hinged-fixed, at the other side thereof, to one end of the handle 160.
The related art is operated as follows. When a user pulls the upper operation lever 162 to be adjacent to the body 111 by a thumb and the like in a state of grasping the handle, the operation rod 120 in the body 111 fixed to the handle 160 compresses and the spring 130 and is elastically moved. Accordingly, a pair of operation parts 153, which is hinged-coupled by the pin 121 at a lower portion of the operation rod 120, is pulled upward in a state of being supported by the link pieces 141 and 142.
The opposite operation parts 153, which are hinged-coupled to the opposite link pieces 141 and 142 by the pin 121, are rotated about a hinge coupled with the tongs part 150 and the link pieces 141 and 142 by the pin 121, and thus the operation parts 153 are closed to face each other. Furthermore, the lower tongs parts 151 also approach to face each other, thereby easily picking up chestnut burrs between the lower tongs parts 151.
When the upper operation lever 162 attached to the body 111 is released, the operation rod 120 is moved reward by elastic restoration force of the spring 130. Consequently, the opposite operation parts 153 are opened about the hinge coupled with the tongs part 150 and the link pieces 141 and 142 by the pin 121 in opposite directions, and the opposite lower tongs parts 151 are opened outward so as to be pushed to each other, and thus the lower tongs parts 151 are returned to an original position.

Each of the low tongs parts 151 has a saw - toothed shape at opposite slope surfaces of an end thereof, thereby picking up chestnut burrs. The fixed lever 163 is fixed, at one end thereof, to an outer peripheral open of one side of the body 111 while being hinge - situate, at the early side thereof, to one end of the handle 160. 
 The related art is operated as follows. When a user pulls the upper process lever 162 to be adjacent to the body 111 by a thumb and the like in a state of grasping the handle, the operation perch 120 in the body 111 fixed to the handle 160 compresses and the spring 130 and is elastically move. Accordingly, a couple of process parts 153, which is hinged - coupled by the pin 121 at a humble portion of the operation rod 120, is pulled up in a state of being supported by the link pieces 141 and 142. 
 The diametric operation parts 153, which are hinged - coupled to the opposite connection pieces 141 and 142 by the fall 121, are rotated about a hinge match with the tongs part 150 and the radio link pieces 141 and 142 by the pin 121, and thus the operation parts 153 are close to face each early. Furthermore, the lower tongs parts 151 also approach to confront each early, thereby easily picking up chestnut bur between the lower tongs parts 151. 
 When the upper operation lever 162 attached to the body 111 is released, the operation gat 120 is moved reward by elastic restoration force of the spring 130. Consequently, the opposite operation part 153 are open about the hinge coupled with the tongs part 150 and the liaison pieces 141 and 142 by the pin 121 in diametric directions, and the opposite lower tongs parts 151 are opened outward so as to be pushed to each other, and thus the lower tongs parts 151 are return to an original position.
