Background technology
Sweep-saw is a kind of electric tool of cutting saw usefulness, conversion base plate angle as required usually during use.Common sweep-saw will use inner hexagon spanner as instrument when conversion base plate angle, regulates quick and convenient inadequately.Chinese patent 200620101214.9 discloses a kind of sweep-saw panel assembly that refoots fast, on the arch sheet of base plate, offer board slot, arch face is provided with location-plate and base plate pressing plate on arch sheet, the interior arch face of arch sheet is provided with cushion block and spanner, it is hinged that plate pin on the location-plate passes pressing plate and cushion block and spanner, one end of spanner is provided with the convex piece, and conflicting by this convex piece and cushion block compresses location-plate.This device need not to use inner hexagon spanner as instrument when regulating the base plate angle, regulate quick and convenient, but also exist not enough: the height of the convex piece of spanner one end is unadjustable, in the process of base plate quick adjustment, the unavoidable not tight situation of card, the positioning and locking poor effect of occurring.
Summary of the invention
In order to solve the above-mentioned deficiency of existing sweep-saw, the utility model proposes a kind of sweep-saw of locating the band base plate quick adjustment mechanism firm, that locking effect is good.
A kind of sweep-saw with base plate quick adjustment mechanism, comprise sweep-saw body and base plate quick adjustment mechanism, on the described sweep-saw body saw blade is installed, described base plate quick adjustment mechanism comprises the base plate that sets up arch sheet, described arch sheet cooperates with the bottom arc surface of described sweep-saw body, have board slot on the described arch sheet, the interior arch face of described arch sheet is provided with cushion block, and the opening that passes for saw blade is arranged on the described base plate; Be equipped with holding screw on described board slot and the cushion block, be socketed with nut, driving lever on the described holding screw, the head of described nut and described driving lever is positioned at the trough of described sweep-saw body, corresponding upper and lower boss is arranged between the two, when upper and lower opposite tower, the height sum of described nut and driving lever head equals the height of described trough, when upper and lower boss staggers, the height sum of described nut and driving lever head is less than the height of described trough, and the lower end of described holding screw is connected with adjusting nut; Described arch sheet is provided with the locking slot that is intervally arranged, and locking member passes in described cushion block, the locking slot locking hole to the casing, and base plate is located.
Further, described locking member is an angle modulation screw, and the screw thread with the angle modulation screw coupling is arranged on the described cushion block.
Further, described arch sheet is provided with the scale of sign base plate angle.
Preferably, described locking slot is distributed on a side of described arch sheet.
Technical conceive of the present utility model is: stir driving lever, upper and lower boss between driving lever head and the nut is staggered, thereby nut and casing produce the gap of rotating for base plate, unclamp angle modulation screw, rotary bottom plate is to required angle, the locking angle modulation screw passes in described cushion block, the locking slot locking hole to the casing it, and base plate is located.Stir driving lever at last, make upper and lower opposite tower between driving lever head and the nut, nut and driving lever wedging are finished the adjusting of base plate angle in trough.
The beneficial effects of the utility model are: (1) by angle modulation screw location, the angle of regulation range of base plate is big, locate firm, locking effect good; (2) can regulate base plate, easy to use without instrument.
