The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Structure of the present invention sees that accompanying drawing 1 is to shown in Figure 5.Hand saw capable of modifying cutting angle, the foregrip 2 and the back handle 11 that comprise injection mo(u)lding, the cavity of foregrip 2 and back handle 11 top correspondences is equipped with by what the metal body constituted sets a roof beam in place 15, for weight reduction and be convenient to hold, make things convenient for the user to operate, foregrip 2 and back handle 11 are plastic injection-moulded forming, and foregrip 11 handle portion are injected with plastics or the rubber layer of being convenient to hold 18 with back handle 11 handle portion; Set a roof beam in place and 15 form for metallic aluminium or aluminium alloy compression casting.The 15 inner chamber front ends of setting a roof beam in place are equipped with elastic component 16, and last elastic component 16 front end apical graftings are on foregrip 2 cavity walls, and standby saw blade 14 1 ends of 15 inner chambers of setting a roof beam in place are inserted in last elastic component 16 rear ends then apical grafting; Back handle 11 upper ends are connected with rolling cover 12, and this rolling cover 12 is shaped on and can covers the extension end cap 12a that back handle saw blade is gone into notch, and this rolling cover 12 is withheld standby saw blade 14 other ends; For keeping thrust evenly reliable, elastic component 16 is fixed with the spring 162 of push pedal 161 respectively for two ends.For making things convenient for complex environment, change saw blade when especially making things convenient for work high above the ground, it is 1 to 10 that 15 inner chambers of setting a roof beam in place have the standby saw blade 14 of storage.
Foregrip 2 has lower through-hole, and this lower through-hole front end is provided with adjusting nut 1, and pre-installed round pin 5a of front tension bar 5 connects adjusting nut 1 to the lower through-hole line that front sequence has passed preceding angle demodulator 4, preceding elastic component 3 and the foregrip 2 of adjusting saw blade sawing angle; The bump body of radian spacings such as preceding angle demodulator 4 peripheries are shaped on, foregrip 2 lower end through-hole wall bump bodies then match with preceding angle demodulator 4 periphery bump bodies;
Be the optimum tight assembling, the cover plate enlarged diagram as shown in Figure 4; Cover plate 8 is shaped on forward recess 8c and rearward recess 8b, and back angle demodulator 9 lordosis recess 9a are seated in the cover plate 8 forward recess 8c, and back angle demodulator 9 9b of opisthosoma then are seated in the cover plate 8 rearward recess 8b; And back handle cavity of resorption also cooperates the groove 11b that is shaped on storing back angle demodulator 9 opisthosomas.Back handle schematic perspective view as shown in Figure 5.
Get standby saw blade, only need rolling cover 12 is raised, the standby saw blade 14 that is positioned at 15 inner chambers of setting a roof beam in place ejects under the effect of elastic component 16 automatically, can take out work saw blade 6 to be installed after, only need rolling cover 12 closed standby saw blade 14 to be fastened to compress.
Use needs for satisfying different saw cutting angles, when tuning saw cutting angle, unscrew adjusting nut 1, move behind the front tension bar 5 and can take off work saw blade 6, continue to unscrew adjusting nut 1, after continuing, moves by front tension bar 5, preceding angle demodulator 4 moves after under the effect of preceding elastic component 3, has lower through-hole up to breaking away from foregrip 2, angle demodulator 4 before tuning according to required saw cutting angle, in like manner, back angle demodulator 9 is also done corresponding tuning; The preceding angle demodulator 4, the back angle demodulator 9 that mix up saw cutting angle are respectively charged into, screw adjusting nut 1 and get final product.Adjusting nut 1 needn't screw out and can tune saw cutting angle fast; And the angular range that tunes is 360 degree.
It is safe and efficient, simple and compact for structure that this handsaw has the loading and unloading saw blade, the advantage that sawing angle adjustment scope is big.
Though the present invention illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
