Description
Technical field
The utility model belongs to field of power tools, particularly relates to a kind of saw blade clamping device.
Background technology
The combination of reciprocating type electric saw comprises the strip saw blade that a body and a group are located at this body one end, by the drive of the reciprocating mechanism that this body configures, this saw blade just can on straight line back and forth movement, saw effect is cut to produce, due to saw blade contact with work object after can cause loss, so after using a period of time, saw blade must be changed.
At present, the connected mode between reciprocating saw blade and reciprocating saw sliding bar is all that screw is directly fixed on saw blade on the slide bar of reciprocating saw, and handling saw blade is complicated.
Utility model content
The purpose of this utility model is to provide a kind of saw blade clamping device, is intended to solve current reciprocating saw blade and adopts screw mode to be connected with reciprocating saw sliding bar, the problem of handling saw blade complexity.
The utility model realizes like this, a kind of saw blade clamping device comprises the saw blade seat and saw blade clamping mechanism that are configured in electric saw body one end, described saw blade clamping mechanism comprises a holding spanners, a back shaft, a U-shaped elasticity iron bar, with a pair return spring, saw blade sliding bar sleeve is provided with in described saw blade seat, saw blade sliding bar sleeve lining both sides are provided with pair of sliding groove, sliding tray tilts outside saw blade sliding bar sleeve, sliding tray side-lower is provided with a back shaft, U-shaped elasticity iron bar is arranged in sliding tray, U-shaped elasticity iron bar openend is opened laterally, the open end of U-shaped elasticity iron bar is the saw blade gripper jaw of infolding, return spring to be arranged on above gripper jaw and to withstand gripper jaw, holding spanners and back shaft form lever construction, one end of holding spanners is positioned at saw blade seat outside, the other end can contact with U-shaped elasticity iron bar close segments.
Further, described saw blade sliding bar sleeve cross section is rectangle, offers the wire cylindrical void of a clamping saw blade in the axial direction.
Further, bottom saw blade seat, be provided with a spanner room with buckle, holding spanners exposed portion is positioned at spanner indoor.
effect gathers
Saw blade clamping device of the present utility model, form lever construction by holding spanners and back shaft, pull holding spanners by U-shaped elasticity iron bar jack-up, saw blade gripper jaw skids off from the locating hole of saw blade can take off saw blade, avoid the problem that traditional clamp method needs knockout screw, easy to use.
