Abstract

The utility model discloses a hand-held electric groove cutting machine, comprising a host machine (1), a base plate (3), a saw bit (12), a saw bit casing and a handle (20); the saw bit casing is assembled by inner and outer casings (6, 5); the saw bit casing is hinged with the base plate (3); the host machine (1) is fixed on the inner casing (6); the saw bit (12) is fixed on a host machine output shaft (2); the inner and outer casings (6, 5) are provided with a drawing-off dust path (19) consistent with the tangential direction of the saw bit (12) which clockwise rotates; the chamber of the handle (20) is connected with the drawing-off dust path (19); the handle (20) is integrated with the inner and outer casings (6, 5). Adopting the above structure, the drawing-off dust process is smoother, the mechanical strength is firmer and the streamline model of the appearance is more beautiful; moreover, the accident of oversized chops being discharged can be prevented; the utility model has the advantages of simple and reasonable structure, good effects of drawing-off dust and dust prevention, long service life, good reliability and safety performance, etc.

Description

The hand-hold electric grooving machine

Technical field

The utility model relates to a kind of hand held electric tool, particularly a kind of groover of the operation of slotting on building and ornament surface.

Background technology

Existing hand-hold electric grooving machine is because at high and the liking of user extremely of building such as wall, ground, table top and ornament surface fluting efficient, its efficient is more than 5 times of artificial fluting; But there is following defective in existing groover: the one, and saw blade counterclockwise rotates, can only back operation during cutting, dust discharge and the same direction of advancing, inside and outside case and handle split design, complex structure, dust discharge and dustproof weak effect, inconvenient operation; The 2nd, on the inside and outside case corresponding, protective cover is not set with saw blade, the fragment wearing and tearing that inside and outside case is discharged from easily, service life is short, and excessive fragment is discharged from and meets accident; The 3rd, prevent the restraint device of unexpected cutting or do not have, or operation inconvenience, misoperation appears easily, reliability and poor stability.

Summary of the invention

For solving the problems referred to above that existing hand-hold electric grooving machine exists, the utility model provides a kind of simple and reasonable, dust discharge and the good hand-hold electric grooving machine of good dustproof effect, long service life, reliability and security performance.The technical scheme that its technical problem that solves the utility model adopts comprises main frame, base plate, saw blade, saw blade case, handle, the saw blade case is combined by inside and outside case, saw blade case and base plate hinged, main frame is fixed on the inner can, saw blade is fixed on the host output shaft, described inside and outside case is provided with the dust discharge passage consistent with the saw blade tangential direction that turns clockwise, and the inner chamber of handle links to each other with the dust discharge passage, and handle and inside and outside case fuse.

For the ease of fixedlying connected with dust collect plant, the end of described handle is provided with the joint that is connected with dust collect plant, and joint and handle fuse.

Directly touch with the inside and outside cover shell joint in order to prevent to cut fragment, reduction of service life, excessive fragment is discharged from and meets accident, described inside and outside case be provided with and the corresponding shelter-clad of saw blade, the shelter-clad corresponding with the dust discharge channel entrance is provided with grid.

In order to control depth of cut, be fixed with scale on the described base plate, be provided with depth of cut adjusting pressing plate by regulating bolt on the scale.

In order to prevent the unexpected cutting of groover, described handle below is hinged with the trigger-type limit button, and an end of limit button withstands on the scale.

Conveniently moving in order to cut is provided with the axis of rolling before and after the described base plate.

After adopting said structure, the rotation of saw blade clockwise direction, the dust discharge passage is along the tangential direction setting of saw blade, and saw blade case and handle fuse, and not only dust discharge is more smooth and easy, and mechanical strength is more firm, and the exterior flow line modelling is more attractive in appearance; The setting of shelter-clad not only can prolong the service life of saw blade case greatly, and can prevent that excessive fragment is discharged from and meets accident, but and simplified processing process; The setting of scale and trigger-type limit button not only can be controlled depth of cut, and can prevent unexpected cutting; Have characteristics such as simple and reasonable, dust discharge and good dustproof effect, long service life, reliability and security performance be good.
