Abstract

The utility model relates to an electric tool, in particular to a saw support of an electric curved saw, which comprises a saw support frame, a rotation shaft, clamping springs, chucking fixtures and a rolling core, wherein the rolling core is arranged between the two chucking fixtures, the rolling core and the two chucking fixtures are jacketed to the rotation shaft, the rotation shaft is arranged on the saw support frame, and the clamping springs are arranged between the saw support frame and the chucking fixtures. The utility model has the beneficial effects that the clamping springs on the two sides of the chucking fixtures guarantee that the chucking fixtures effectively clamp a saw blade and the saw blade is kept in the middle position between the chucking fixtures without deviation, which improves cutting accuracy and quality.

Description

The saw holder of electric jig saw

Technical field

The utility model relates to the saw holder of a kind of electric tool, particularly a kind of electric jig saw.

Background technology

The saw holder of existing electric jig saw generally comprises saw carriage and saw pallet, saw blade props up in the slit of saw pallet, and when saw blade moved up and down, the saw pallet pivoted on the saw carriage, the saw pallet only plays a pushing and pressing effect to saw blade, can not guarantee saw blade rectilinear motion up and down; In use, up and down during high-speed motion, saw blade can swing saw blade, is offset, and influence cut quality, and the phenomenon that saw blade ruptures can take place when serious.

Summary of the invention

The purpose of this utility model is to provide a kind of electric jig saw saw holder of the saw blade of stable holding long-term effectively.

The technical scheme that its purpose that realizes the utility model adopts is: a kind of saw holder of electric jig saw, have saw carriage, rotating shaft, fastening spring, chuck, roll core, the described core that rolls is positioned in the middle of two chucks, rolling core and chuck is enclosed within the rotating shaft together, described rotating shaft is arranged on the saw carriage, between saw carriage and chuck fastening spring is set.

Further describe structure, roll the core centre and have the trapezoidal stopper slot of a circle; Rotating shaft is located by jump ring on the saw carriage; Fastening spring is disk spring, cylindrical spring, elastomeric pad or rubber spring etc.

The core that rolls between the chuck rolls around axle, and saw blade is played the pushing and pressing effect, and the spring between chuck and the saw carriage is used to keep the clamping of chuck to saw blade, and saw blade is not offset.

The beneficial effects of the utility model are: the fastening spring on chuck both sides has guaranteed the effective clamping of chuck to saw blade, and the saw blade that has guaranteed simultaneously to be in the middle of the chuck mediates all the time, does not shake, drift, has improved cutting precision.
