A clamp module 200 is provided at the end of the saw blade operation bar 3 so that the saw blade S is detachable,
The clamp module 200 has a saw blade so as to be orthogonal to the main clamp groove 210, one side of which is open to the end of the saw blade operating bar 3 and the main clamp groove 210, while having a negative shape in the longitudinal direction of the saw blade operating bar 3. A multi-clamp groove 220 extending in the width direction of the operating bar 3 to form a +-type keyway 230, a clamp hole 240 penetrating the center of the +-type keyway 230 and fastening a bolt, and a +-type keyway 230 A top system for non-vibrational high-place work, characterized in that it includes a +-type key 250 in which a through hole 252 is formed to be engaged with the keyway 230 and fastened with a bolt. According to claim 4,
The saw blade (S) is guided in linear movement by the distance maintaining module 300,
The distance maintenance module 300 has one end fastened to the output port 13 by bolts and the other end formed in an arcuate curvature to be spaced apart from the saw blade S, and the expansion wings 312 protrude on both sides to be cut. The ring arm 310 mounted on the water, the extension arm 320 extending to intersect the saw blade S at a predetermined angle at the end of the ring arm 310 and mounted on the object to be cut, and the extension arm 320 It is formed in a reduced size compared to the thickness of the ring arm 310, and the locking jaw portion 330 formed by the difference in thickness between the extension arm 320 and the ring arm 310 is bolted in a state accommodated in the locking jaw portion 330. , including a slot block 340 in which a slot groove 342 is formed so that the body area S2 of the saw blade S, except for the blade area S1, is locally accommodated,
The slot block 340 is formed of a material that is softer than the saw blade S containing synthetic resin,
Characterized in that the body area S2 of the saw blade S is accommodated in the slot groove 342, and the blade area S1 is spaced apart from the extension arm 320 by the thickness of one side of the slot block 340 so as to be non-contact. Vibration-free top system for high-place work. According to claim 1,
A plurality of balance holes 52 are formed around the main shaft 31 in the bevel gear 50, and the balance holes 52 gradually increase in size toward the crankshaft 42 of the crank arm 40. The top system for vibration-free high-place work, characterized in that the area of the bevel gear 50 corresponding to the crankshaft 42 is formed to be expanded and lightened compared to other areas by the balance hole 52.
