In the related art, an 'excavator forceps drive structure' similar to the present invention has been registered by Utility Model Registration No. 333745 as shown in FIG.

That is, the forceps assembly 100 is integrally formed with one end of the coupling portion 110 and the coupling portion 110 which is hinged to the arm, and drives the pair of first and second tongs 130 and 140 simultaneously. It consists of a bracket that is provided with a drive cylinder 122 and the first to third drive links (124, 126, 128). The bracket is in a state in which the three sides are open, and a drive cylinder fixedly installed at a predetermined position in the bracket so that the cylinder rod (not shown) is stretched and driven in one direction by the hydraulic force supplied through the hydraulic line therein. And a first driving link 124 hinged to one end of the cylinder rod and the other end hinged to the first tong 130, and one end corresponding to the driving of the first driving link 124. Is coupled to a predetermined edge of the first driving link 124 and the other end is coupled to one end of the third driving link 128 and the driving force of the first driving link 124. Third drive link 128, the second tong 140 is fixed to the other end to receive the second drive link 126 via the medium to drive the second tong 140 together with the first tong 130. ) Is included. Here, the driving cylinder 122 has a central portion thereof fixed by a fixed shaft a in the bracket, and the first driving link 124 has both ends thereof when the cylinder rod of the driving cylinder 122 stretches. The first pivot center (b) is formed so that the center portion is hinged in the bracket so as to rotate in one direction, the third drive link 128 is the second driving link 126 to drive the driving force of the first drive link (124) And the first pivotal central shaft (b) to be rotated in a direction opposite to the rotational direction of the first driving link 124 to grip a predetermined object by the first and second tongs 130 and 140. A second pivotal center c is formed in which the central portion of the collinear bracket is hinged.

The prior art structured as described above shows the state of the tongs of the excavator in normal times, so that the pair of tongs 130 and 140 are kept open to grasp a predetermined object. When the rock, the scrap metal, etc. are gripped from such a state, the object is contained in the pair of tongs 130 and 140, and the hydraulic pressure is applied to the drive cylinder 122 to drive the drive cylinder 122 from the predetermined control device. When the hydraulic force is provided through the line, the cylinder rod of the driving cylinder 122 is stretched and driven in one direction. Then, one end of the first driving link 124 coupled to one side of the cylinder rod of the driving cylinder 122 corresponds to the stretching direction of the cylinder rod to protrude out of the bracket to move the first pivot center shaft b. It is rotated counterclockwise toward the center, and at the same time, the first tongs 130 are also rotated counterclockwise to grip one side of the object to be gripped.

The drive link 128 is hinge-driven in the clockwise direction with the second pivotal center (c) hinged in the bracket in the same structure as the first pivotal center (b). As a result, the second tong 140, which is coupled to the end of the third driving link 128, is driven clockwise to grip the other part of the object held by the first tong 130. As such, even if only one driving cylinder 122 is driven, the first, second, and third driving links 124, 126, and 128 coupled to the driving cylinder 122 are driven to be interlocked and driven. The tongs 130 and the second tongs 140 also receive a driving force to be able to grip and transport the object.
