易なさしめるものである。An embodiment will be described below with reference to the drawings. Reference numeral 1 denotes a blade member having a U-shaped notch 2 on one side, and downward and upward blades 3 and 4 formed on the upper and lower edges of the notch 2. The lower end of the blade member 1 is attached to the tip of the elongated shaft rod 10, and the blade holder is press-fitted into the bifurcated blade holder 5' of the member 5, and the two pins 6.6
The blade holder is connected to the part 5' by piercing it at a symmetrical position between the part 5' and the blade member 1, and the blade holder has a pin 6.6 projecting from one side of the part 5'. A small hole I perpendicular to the axial direction of the pin 6 and 6' is provided at the tip of each of the pins 6 and 6'. By inserting and locking the pins 6, 6'
In addition, by pressing and closing both legs of the spring 80 against the expansion bias, the legs of the spring 8 can be disengaged from the small hole 7, and the pin 6.6' can be easily removed. It can be pulled out, thereby making it easy to replace the blade member 1.
尚上記刃部材１の上下端に設けられた通孔９゜９′は、
該刃部材１の刃３，４を上下逆に使用するため刃部材を
ひつくり返した場合該通孔９，９′にピン６．６′を刺
通し、刃受は部５′と連結するためのものである。The through holes 9°9' provided at the upper and lower ends of the blade member 1 are as follows:
When the blade member 1 is turned over so that the blades 3 and 4 of the blade member 1 are used upside down, the pins 6 and 6' are inserted into the through holes 9 and 9', and the blade holder is connected to the part 5'. It is something.

いる。Further, another shaft rod 12 into which a hammer member 11 is loosely fitted is screwed to the lower end of the shaft rod 10.
The impact receivers 13 and 14 of the hammer member 11 are fixed to the middle and lower end portions of the shaft rod 12 that sandwich the hammer member 11, and the impact receivers are attached to the shaft rod 12 and the impact receiver above the member 13. A handle portion 15, 16 is formed on the shaft portion at the lower end of the member 14.
また上記ハンマ一部材１１の下端にはハンマ一部材１１
０重量を適宜調整するためのナツト状の重量継足し部材
１７が着脱自在に螺着しており、該重量継足し部材１７

マ一部材１１に対する螺着をとげば、該重量継足し部材
１７は軸杆１２より抜き取ることができるものである。Further, a hammer member 11 is provided at the lower end of the hammer member 11.
A nut-shaped weight addition member 17 for appropriately adjusting the zero weight is removably screwed onto the weight addition member 17.
The diameter of the impact receiver at the lower end of the shaft rod 12 is larger than the diameter of the member 14, and if this weight addition member 17 is screwed to the hammer member 11, the weight addition member 17 can be attached to the shaft rod. It can be extracted from 12.
本考案は以上のように構成されるところから、ハンマ一
部材を衝撃受は部材に衝突させ、該衝突によって生じた
衝撃力によって刃部材に形成された上下刃を枝の上下側

うるものであり、従って作業に従事する人の疲労も少な
く作業能率も向上しその実用的効果は極めて犬である。Since the present invention is constructed as described above, the hammer member collides with the impact receiver member, and the impact force generated by the collision causes the upper and lower blades formed on the blade member to bite into the upper and lower sides of the branch. When cutting down branches by using a hammer, depending on the age and gender of the person involved in the felling work, the size of the branch to be felled, etc., it is possible to change the weight adding member that is removably attached to the hammer part as appropriate. However, tree branches can be easily cut down, and the practical effects of this method are extremely high, as the fatigue of the workers is reduced and work efficiency is improved.
