Description
Technical field
The utility model relates to a kind of cutter, specifically is a kind of spade chisel.
Background technology
Traditional chisel, its cutter hub and handle are fixing non-removable, and the anterior blade of cutter hub is the straight knife body, and the straight knife body just is meant that the width of whole blade equates, the width of cutter hub blade foremost also equates with blade.There is following defective in this chisel: at first, because cutter hub and handle are on-dismountable, and handle often damages easily, in case handle damages, whole chisel just is difficult to use even scrap; Secondly, blade blade width foremost is less, during processing work and the contact area of workpiece little, the speed of processing work is slow, efficient is low.
Summary of the invention
The technical problem that the utility model will solve is, the spade chisel that working (finishing) area was big, speed is fast, efficient is high when the detachable and processing work of a kind of cutter hub and handle was provided.
The technical solution of the utility model is, a kind of spade chisel is provided, and it comprises cutter hub and handle; Cutter hub comprises anterior blade and back bar; Handle is through with centre bore, and handle rear end is provided with the termination, and the rear end that back bar passes handle center hole and back bar is connected with the termination is removable; Be provided with latch between handle and the back bar, blade is made up of front wide and rear narrow spade blade and straight knife bar foremost.
The spade chisel of the utility model compared with prior art has the following advantages:
Because the back bar is connected with the termination is removable; Like this, extract the latch between handle and the back bar, then back bar and termination are taken apart; Just can make things convenient for smoothly cutter hub is separated with handle; So after if handle damages, can change timely and conveniently, be difficult to after having avoided handle to damage to use even situation that whole chisel is scrapped; Because blade comprises foremost front wide and rear narrow spade blade and straight knife bar, and like this, the width of blade obviously increases, the contact area of blade and workpiece also increases during processing work, so process velocity is fast, efficient is high again.
As improvement, the termination is made up of end cap and internal thread sleeve pipe, and the internal thread sleeve pipe is contained in the centre bore; The external diameter of end cap is greater than the aperture of centre bore, and back bar is provided with external screw thread, and back bar and internal thread sleeve pipe screw; Like this; The end cap of termination is stuck in outside the centre bore of handle, and the back bar and the termination of cutter head screw, and it is all convenient to make cutter hub be connected, dismantle with handle.
As improving again; Handle is provided with radial direction through hole; The position corresponding with radial direction through hole is provided with radially pin-and-hole on the back bar of cutter hub, and latch passes radial direction through hole and inserts radially in the pin-and-hole, like this; Can be quickly and easily that cutter hub and handle is circumferentially spacing through latch, prevent that the cutter hub rotation from getting loose from the internal thread sleeve pipe of termination.
