Specific implementation mode
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, a kind of convenient hand saws of dismounting saw blade, including saw frame 1, fixed saw
The rear end fixed part 2 of item, 1 bottom of the saw frame are equipped with inner cavity, and the interior intracavitary is equipped with elastic mechanism, and the elastic mechanism is with after
Hold fixed part 2 hinged, the bottom of the saw frame 1 is equipped with control mechanism, and the control mechanism is interconnected with elastic mechanism, described
Control mechanism controls the elastic of elastic mechanism.When saw blade is installed in dismounting, the bottom that need to only adjust saw frame is equipped with control mechanism, control
The rear end fixed part 2 that mechanism processed will drive elastic mechanism to adjust fixed saw blade makes dismounting installation saw at a distance from front end
Item becomes simple and convenient, installs tensile force that is rear and can guarantee saw blade.
In embodiment, as shown in Figure 2, Figure 3, Figure 4, the elastic mechanism includes the No.1 connector being connect with control mechanism
3,3 one end of institute's No.1 connector is hinged with saw frame 1, and the other end is hinged with No. two connectors 4, sliding part 5 and No. three companies successively
Fitting 6, the sliding part 5 are slided in interior intracavitary, and 4 axial length of No. two connectors is adjustable.The both sides of the inner cavity are equipped with
Sliding slot 7, the sliding part 5 are mounted in the sliding slot 7 on both sides.Sliding slot 7 ensures that sliding part 5 is moved in interior lumenal levels, can also have
Effect prevents sliding part 5 from being dropped out from the interior intracavitary of saw frame 1；No. two 4 axial lengths of connector are adjustable, can be according to saw blade to different materials
Different tensile forces makes adjusting required for material.
