Described locating slot can be set to rectangle, square, trapezoidal or triangle; Described locating slot the best is set to rectangle; The rectangle locating slot cooperates tight, is difficult for during work becoming flexible, thereby improves the quality of sawing work.
Described working head middle part is provided with front bayonet slot, and the front portion of described fuselage is provided with preceding claw, and this preceding claw matches with described front bayonet slot; Its effect is to make to have good being connected with fixing between described working head front end and the described fuselage.
Described working head rear portion is provided with the back draw-in groove, and the middle part of described fuselage is provided with the back claw, and this back claw matches with described back draw-in groove; Its effect is to make to have good being connected with fixing between described working head rear end and the described fuselage.
Described fuselage described back claw and described before between the claw, also be provided with a plurality of support claws, this support claw contacts with the external rear face of described working head; Above structure and be arranged so that the integral body of described working head and described fuselage between have good coupling stiffness, to improve its operating accuracy and operating efficiency.
The present invention is owing to adopted the saw blade can be along perpendicular to rotational structure in the plane of the direction of motion of described saw blade with respect to this fuselage, compared with prior art, its advantage is to make originally only to keep the saw blade of a fixed angle that a plurality of use angles can be arranged, thereby improve its operation comfort, can increase work efficiency greatly again.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to view;
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 show an embodiment of electric saw of the present invention, comprise the working head 2 of a translator 21, and the head device of this working head has reciprocating saw blade 1; Rotatable connection one fuselage 4 of the afterbody of this working head; Promptly this working head can be can be along rotating in the plane perpendicular to the direction of motion of saw blade with respect to this fuselage.
The front end of this fuselage 4 is provided with the location cage knob 3 of a tape guide rail; The rear end of this location cage knob connects a spring 31; The other end of spring 31 is positioned on the fuselage 4.Location cage knob 3 can be reciprocating along guided way.The front end of location cage knob 3 is provided with location buckle 33, matches with working head, and working head adopts manually rotation; Perhaps adopt by transmission mechanism and drive the working head rotation.
The afterbody of working head 2 is provided with a plurality of circumferentially uniform locating slots 6 of chuck mode, as shown in Figure 1, 2; This location cage knob 3 matches with locating slot 6.
