It is a shock tube that is projected on the circumferential surface. One end of the tension coil spring 5 is hooked on the hooking metal 6 at the base end of the blade mounting tube 1 and the hooking rod 7 provided at the base of the impact tube 3, respectively.
In the shock tube 3. An operating rod 10 is connected to the base end of the impact tube 3 by a connecting rod 9. Reference numeral 11 denotes a slot formed in the impact tube 3 into which the impact piece 12 protruding from the blade mounting tube 1 is inserted.

とができる。Operation: When the sickle 2 is hooked on a tree branch, the impact tube 3 is pulled down against the tension coil spring 5, and the receiving piece 12 is hit by the driving collar 4, the tension coil spring 5 pulls the blade with a force. The attachment pipe is pulled, and the impact force allows the cutting blade 2 to cut off the branch.

い。[Effects] According to the present invention, since the blade attachment tube is pulled down by hooking a sickle on a branch and utilizing the elastic force of the coil spring 5, the elastic force of the coil spring increases due to human power. In other words, the elasticity of the coil spring is applied to the sickle after the sickle is manually pulled on the branch and pulled,
Two-stage stance gives a branching impact. Therefore, even a relatively thick branch can be smoothly cut by the force of the sickle and human impact, and the performance as this kind of branch cutting blade is improved. Further, since the blade mounting tube 1 moves up and down by being guided by the receiving piece 12 fitted in the groove hole 11, the blade mounting tube 1 always moves straight and there is no fear of shaking.
