Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
Referring to Fig. 1~Fig. 4, a kind of handheld cutting device of pipe fitting of the present invention, including hand grip portion 10, link block
20 and can free bend cutting saw blade 30.Hand grip portion 10 and link block 20 there are two and be symmetrically set in cutting saw blade 30
The one end at both ends, link block 20 is connected with hand grip portion 10, the rotatable phase in end that the other end passes through pin and cutting saw blade 30
Even.It is provided along its length gulleting 40 at least one side of cutting saw blade 30.
First embodiment：
Link block 20 is triangular structure, and the tip of link block 20 is rotatably connected by pin 51 with cutting saw blade 30.
The end of link block 20 offers strip-shaped hole, and hand grip portion 10 is banded structure.Hand grip portion 10 be arranged in corresponding strip-shaped hole and
Its both ends is fixedly linked to form cyclic structure.
Cutting saw blade 30 includes several cutting rods 31 and connection strap 32, and cutting rod 31 and the interval of connection strap 32 are arranged and pass through
Axis pin part 52 joins end to end successively, and the unidirectional side of all cutting rods 31 is equipped with gulleting 40.
Gulleting 40 is structure as a whole with cutting rod 31, sets to the concave to form gap 41 in the middle part of gulleting.Gap
Gulleting is separated into the first cutting teeth portion 42 and second by 41 cuts teeth portion 43.First cutting teeth portion 42 is rectangular configuration, the
Two cutting teeth portion 43 are triangular structure.First cutting teeth portion 42 and second is cut on the lateral surface of teeth portion 43 and in gap 41
It is equipped with cutting edge.The cutting edge of second cutting teeth portion 43 is higher by the cutting edge of the first cutting teeth portion 42, and cutting is made to imitate
Fruit is more notable.
Gulleting on two adjacent cutting rods 31 is symmetrical arranged.Gulleting on certain cutting rod 31 can also
