Limiting slot 84 offers sliding slot 842 along its length, and pressing board 843 is slidably connected in sliding slot 842.

It the concrete operating principle of the present embodiment and has the beneficial effect that

Working principle:

Adjust the relative position in the strip sliding slot 2 of regulating part 3 according to the actual situation first, and with the first locking member 22 Regulating part 3 and strip sliding slot 2 are locked, interconnecting piece 41 is then adjusted according to the length of practical aluminum alloy bar and adjusted Relative position between part 3, and interconnecting piece 41 and regulating part 3 are locked with the second locking member 32.

After part 3 and interconnecting piece 41 to be regulated fix, aluminum alloy bar one end is placed on angle cutting mold 16, the other end is put On interconnecting piece 41, triggering block 813 is pressed, the direction that triggering block 813 drives frizzen 812 towards close aluminum alloy bar is mobile, from And to push against block 814 and aluminum alloy bar abutting fixation, groove 82 is aligned with limiting slot 84 at this time, and fixture block 831 is in third elasticity The elastic force effect of part 832 is lower and limiting slot 84 is clamped, and then realizes relatively fixed between frizzen 812 and outer sleeve 811.

Start motor after fixing to aluminum alloy bar, corner cut cutter 14 cuts aluminum alloy bar；To aluminum alloy bar After well cutting, pressing board 843 is pressed, fixture block 831 is detached under the promotion of pressing board 843 with limiting slot 84, and frizzen at this time 812 drive the direction for pushing against block 814 towards separate aluminum alloy bar to move under the elastic force effect of the second elastic component 816, block to be pushed against After 814 are detached from aluminum alloy bar, the aluminum alloy bar of well cutting can be taken out from interconnecting piece 41.

When not needing to carry out aluminum alloy bar to be cut, unscrews the second locking member 32 and slide to interconnecting piece 41 far from strip One end of shape sliding slot 2, and be locked with the second locking member 32, it then will unscrew the first locking member 22, rotate clockwise Regulating part 3, by connector 5 and strip sliding slot after regulating part 3 is accommodated in completely in strip sliding slot 2 and with the first locking member 22 2 are locked.

The utility model has the advantages that

Frizzen 812 is driven to make by the way that aluminum alloy bar to be placed on interconnecting piece 41, and by pressing triggering block 813 Block 814 must be pushed against, aluminum alloy bar is pushed against into fixation, so that aluminum alloy bar is held during carrying out corner cut instead of operator, It ensure that the safety of operator, and simple to operate quick.

The clamping of fixture block 831 and limiting slot 84 is realized by pressing triggering block 813 so that pushing against block 814 for aluminium alloy Item, which pushes against, to be fixed, and by press pressing board 843 fixture block 831 and limiting slot 84 are detached from so as to by aluminum alloy bar from even It is taken off in socket part 41, whole process is simple to operate quick.

Since the first locking member 22 is arranged in the company in the first strip through slot 21 and with regulating part 3 and strip sliding slot 2 The place of connecing is locked, so that regulating part 3 is to carry out rotation company around the first locking member 22 relative to strip sliding slot 2 It connects, simultaneously because the first strip through slot 21 is penetrated through with strip sliding slot 2, to connector 5 can be received when not in use It is contained in strip sliding slot 2, to reduce the space occupancy rate of connector 5.

Due to being all connected through a screw thread between regulating part 3 and strip sliding slot 2, between fixture 4 and regulating part 3, thus The connective stability between regulating part 3 and strip sliding slot 2, fixture 4 and regulating part 3 is enhanced, and then has ensured fixture 4 to aluminium Stability when alloy bar is fixed.

By the way that aluminum alloy bar to be placed on interconnecting piece 41, and aluminum alloy bar is pushed against by third locking assembly 8 and is fixed, To hold aluminum alloy bar during carrying out corner cut instead of operator, the safety of operator ensure that.

It is slidably connected in strip sliding slot 2 by regulating part 3 and passes through the first locking member 22 for regulating part 3 and strip Sliding slot 2 is fixed, so as to adjust the relative position in strip sliding slot 2 of regulating part 3 according to the actual situation, thus for behaviour The operation for making personnel provides conveniently.

It is slidably connected on regulating part 3 by interconnecting piece 41 and passes through the second locking member 32 for interconnecting piece 41 and regulating part 3 is fixed, so as to adjust the relative position of interconnecting piece 41 Yu regulating part 3 according to the length of practical cutting aluminum alloy bar, leads to The change of 41 position of interconnecting piece is crossed to enhance the stability that aluminum alloy bar is placed on interconnecting piece 41.

Since the setting of connector 5 is so that interconnecting piece 41 and abutting portion 42 are linked to be an entirety, while connection sheet 52 is indirect The contact area between interconnecting piece 41 and abutting portion 42 is increased, so that the connection between interconnecting piece 41 and abutting portion 42 is more Add stabilization, and then strengthens the whole fixed function to aluminum alloy bar of fixture 4.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
