Detailed description of the invention
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 7, a kind of clamping device of sweep-saw, comprise: reciprocating lever 1, knob 2, knob base 3, holder 4 and saw blade 5, in reciprocating lever 1, be equipped with the first elastic component, the first elastic component is for playing cutter spring 6, play on cutter spring 6 and be connected with and play knife rest 8, play knife rest 8 and be connected with saw blade 5.
In addition, play knife rest 8 front ends and be provided with bullet knife rest locating slot 9, reciprocating lever 1 front end is provided with reciprocating lever locating slot 10, described holder 4 offers slot 11, on saw blade 9, comprise saw blade arm 12, saw blade arm 12 also matches with reciprocating lever locating slot 10 and bullet knife rest locating slot 9 respectively through the slot 11 of holder 4, between reciprocating lever locating slot 10 and bullet knife rest locating slot 9, mutually vertically, jointly locates the centering of saw blade 5.
In addition, knob 2 is connected and forms cavity with knob base 3, holder 4 is located in cavity, and coordinate and be arranged on knob base 3, reciprocating lever 1 is connected with holder 4 through knob 2, on knob base 3, be connected with the second elastic component, the second elastic component is torsion spring 7, saw blade 5 is successively through knob base 3, holder 4 is connected with bullet cutter spring 6 with knob 1, holder 4 comprises 2 holder limited blocks 13, between 2 holder limited blocks 13, form and open shelves 14, open on shelves 14 and be equipped with limiting plate 15, on knob base 3, be provided with 16 and 2 knob base limited blocks 17 of 2 clamping guide pads, knob base limited block 17 matches with holder limited block 13, the rotating seat limited block 17 of knob base 3 is opened after shelves 12 by holder, be screwed on holder limited block 13, limiting plate 15 is inserted into opening in shelves of holder 4, knob base 3 can not be return like this.Clamp guide pad 16 and contact with saw blade arm 12, knob base 3 rotates under the twisting force of torsion spring 7, and the clamping guide pad 16 of rotating seat 3 is along with rotating clamping saw blade 5 gradually.
The clamping device specific works principle of the utility model sweep-saw is as follows: when clamping saw blade 5, as long as when dextrorotation knob the 2 motionless position, when the reciprocating lever locating slot 10 of reciprocating lever 1 aligns with slotting 11 of knob base 3, saw blade 5 is inserted, promote saw blade 5 motionless to saw blade 5, knob 2 and knob base 3 circle round under the active force of torsion spring 7, and the clamping guide pad 16 of knob base 3 promotes saw blade arm 12, clamping saw blade 5, to fastening position, is locked saw blade 9 under the active force that plays cutter spring 6 gradually.While exiting saw blade 5, if by knob 2 to right rotation until rotate motionlessly, saw blade 5 is automatic spring under the effect that plays cutter spring 6.
