  In order to solve the above-mentioned problems, a high branch cutting rod structure includes an extending support tube, a fixed rod, a rotary blade, a control member, and a gripping portion, and a fixed rod including a fixed portion and a movable portion having a bent shape. The end of the cylinder is fixed, and a rotary blade including a blade portion and an interlocking portion is provided on one side of the fixed rod so as to be rotatable. And the operation of the blade portion is an open state in which the blade portion rotates downward and When the blade part is in a cutting state that rotates upward, the blade part comes into contact with the movable part of the fixed rod, and the interlocking part protrudes and extends in the direction away from the blade part. The member interlocks the interlocking part of the rotary blade by connection, and the grip part includes the over and under knives. Possible Is provided on one side of the blade part, and is provided on one side of the blade part of the rotary blade in the undercut, and when the blade part of the rotary blade is in an open state in which it rotates downward, the downward extending direction of the blade part and the extending support cylinder The gist of the present invention is an improved structure of a high-edged shear, characterized in that there is an outwardly-opening angle between the installation axes.

  Compared with the prior art, this device achieves practically advantageous effects such as increasing the width of the maximum cut formed between the blade portion and the movable portion of the fixed rod, thereby increasing the degree of arcing.

  According to the “advanced structure of a high branch cutting rod” of the present invention, the blade portion of the rotary blade opens outwardly between the downward extending direction of the blade portion and the installation axis of the extending support tube 10 depending on the open state in which the blade portion rotates downward. Compared with the known structure in the prior art, the new original structure form and technical features that form an angle increase the width of the maximum cut formed between the blade part and the movable part of the fixed rod, and further increase the degree of arc cutting It is a high eaves cutting structure with practical progress that can be utilized.
