Claims

1. A dual handle power saving rebar hand saw, characterized in that, include: A support frame (1) and an elbow (2), wherein a saw blade (4) is connected between the support frame (1) and the elbow (2) by a steel strip frame (3); The first handle (5) is connected to one end of the support frame (1); Two guard pieces (6) are rotatably disposed on the front and rear sides of the elbow (2), so that the vertical end of the elbow (2) forms a second grip position; And two locking structures are provided at the ends of the handguard (6) to restrict the rotation of the handguard (6) relative to the elbow (2). The locking structures restrict the handguard (6) from rotating to the side position of the elbow (2), thereby adjusting the angle of the second grip position. Each of the aforementioned locking structures includes a guide seat, an end cap (10), and a locking pin (13). The guide seat is disposed on one side of the elbow (2), and the guard piece (6) is rotatably connected to the guide seat. The end cap (10) is disposed on the side of the guard piece (6) and is rotatably connected to the guide seat. Both the end cap (10) and the guide seat have hole structures. The locking pin (13) is inserted into both hole structures at the same time, so that the rotation of the end cap (10) relative to the guide seat is restricted.

2. The dual handle power bar rebar saw of claim 1, wherein: The guide seat includes a rotating shaft (7) and a limiting plate (8), the limiting plate (8) being connected to the end of the rotating shaft (7) away from the elbow (2); The diameter of the limiting plate (8) is larger than the diameter of the rotating shaft (7). The guard (6) is penetrated by the rotating shaft (7) and the guard (6) is attached to the limiting plate (8), so that the guard (6) can rotate relative to the elbow (2) and is not easy to fall off.

3. The dual handle power bar rebar saw of claim 2, wherein: The guard piece (6) includes a steel plate (61) and a wooden handle (62). The wooden handle (62) is attached to the surface of the steel plate (61) to improve the grip fit of the elbow (2) end.

4. The dual handle power bar rebar saw of claim 3 wherein: The upper end of the steel plate (61) is provided with a rotating hole (611), and the rotating hole (611) is rotatably connected to the rotating shaft (7). The lower end of the handguard (6) is provided with a pin hole (621) that passes through the wooden handle (62) and the steel plate (61). The elbow (2) is provided with a positioning hole (9). A positioning pin (622) is provided in the pin hole (621) that passes through the positioning hole (9). The positioning pin (622) makes the handguard (6) fit against the elbow (2).

5. The dual handle power bar rebar saw of claim 3 wherein: The end cap (10) is a hollow cylindrical cap with an opening on one side. The open end of the end cap (10) is connected to the surface of the steel plate (61), and the other end of the end cap (10) is provided with a first hexagonal hole (11). The guide seat has a second hexagonal hole (12) on its limiting plate (8), and the first hexagonal hole (11) and the second hexagonal hole (12) correspond to the locking pin (13).

6. The dual handle power bar rebar saw of claim 5 wherein: The locking pin (13) has two hexagonal ends of different sizes. The size of the first hexagonal hole (11) is smaller than that of the second hexagonal hole (12). The two hexagonal ends of the locking pin (13) are respectively inserted into the first hexagonal hole (11) and the second hexagonal hole (12).

7. The dual handle power bar rebar saw of claim 4 wherein: The two guard pieces (6) extend out of the elbow (2), and an inner clamping plate (14) is detachably connected between the two guard pieces (6). Each of the positioning pins (622) passes through the inner clamping plate (14), so that the inner clamping plate (14) fills the space between the two guard pieces (6).

8. The dual handle power bar rebar saw of claim 7 wherein: The inner clamping plate (14) has a protrusion (15) at its end, and the bottom ends of the two steel plates (61) are provided with grooves (16), and the protrusion (15) is embedded in the groove (16).

9. The dual handle power bar rebar saw of claim 7 wherein: The end of the inner clamping plate (14) protrudes between the two steel plates (61), and a support rod (17) abuts between the end of the clamping plate (14) and the support frame (1).
