Specific embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings：
In embodiment, as shown in Figure 1, Figure 2, Figure 3 shows, one kind dismounting convenient hand saws of saw blade, including saw frame 1, fixed saw blade
Rear end fixed part 2, the bottom of the saw frame 1 is provided with inner chamber, and elastic mechanism is provided with the inner chamber, and the elastic mechanism is consolidated with rear end
Determine portion 2 to be hinged, the bottom of the saw frame 1 is provided with controlling organization, and the controlling organization is interconnected with elastic mechanism, the control
Mechanism controls elastic mechanism it is elastic.When saw blade is removed and installed, the bottom that need to only adjust saw frame is provided with controlling organization, control machine
Structure will drive elastic mechanism to adjust the rear end fixed part 2 of fixed saw blade and the distance of leading section, make to remove and install saw blade change
It is simple and convenient, after installing and can guarantee that the tensile force of saw blade.
In embodiment, as shown in Figure 2, Figure 3, Figure 4, the elastic mechanism includes a connector being connected with controlling organization
3, the one end of the fixture 3 is hinged with saw frame 1, and the other end joins successively No. two connectors 4, sliding part 5 and No. three connections
Part 6, the sliding part 5 is slided in inner chamber, and No. two connectors 4 axial length is adjustable.The both sides of the inner chamber are provided with cunning
Groove 7, the sliding part 5 is arranged in the chute 7 on both sides.Chute 7 ensures that sliding part 6 is moved horizontally in inner chamber, also can be effective
Sliding part 6 is prevented to be dropped out from the inner chamber of saw frame 1；No. two axial lengths of connector 4 are adjustable, can be according to saw blade to different materials
Required different tensile force makes regulation.
In embodiment, as shown in Figure 2, Figure 3, Figure 4, No. two connectors include bolt 8, a long nut 9 and two
