Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chamfering trowel. The problem with conventional chamfering trowels is that the replacement plate fixing plate part is integrated and the angle and surface width are fixed, so they must be used differently depending on the application, and several types of chamfering trowels must be prepared. It had a point.

The present invention was invented to solve such problems and to provide a chamfering trowel that can be freely adjusted in surface width and angle and can be applied to chamfering with various surface widths and angles.

Referring now to FIGS. 1 and 2, which show an example of the embodiment, 1 is a handle, and 2 is an adjusting plate fixed vertically to both ends of the handle 1 in a substantially inverted T-shape. Reference numerals 3, 3, . . . designate screw movement holes that are bored laterally in the horizontal plates 4, 4 of the adjustment plate 2 in a substantially oval shape from the center position to the left and right. 5, 5... is a substantially fan-shaped angle adjustment plate, and angle adjustment holes 6, 6..., which are substantially elliptical in shape and parallel to the outer circumferential surface, are bored in the upper half of the board to adjust each angle. The hole 6 is diagonally intersected with the screw movement holes 3, 3, . . . in the vertical direction, and the screws 7, 7, .
... can be inserted and tightened freely, and by loosening the screw 7, the angle adjustment plate 5 is provided to be slidable vertically on the adjustment plate 2. Reference numerals 8 and 8 designate angle adjusting plates 5, 5... with the handle 1 and the handle 1, with the upper end facing inward and the lower end facing outward, facing each other left and right, at the lower end of the angle adjusting plates 5, 5... This is a replacement painted plate fixing plate that is fixed in the parallel direction. Reference numeral 9 denotes a replacement coating plate for the replacement coating plate fixing plate, which has an almost V-shaped cross section and can be freely inserted into the lower surface side of the left and right replacement coating plate fixing plates 8, 8. A fitting edge 10 is provided by bending the edge. 11 is a scale engraved on the surface of the angle adjustment plate 5. 12 is a scale engraved on the horizontal plate 4.

Because the present invention has such a structure, when the screw 7 is loosened, the angle adjustment plate 5 can slide vertically, and the replacement coating plate fixing plate 8 fixed to the lower end of the angle adjustment plate 5 can move along the curve of the angle adjustment plate 5. The replacement coating plate 9 fitted into the replacement coating plate fixing plate 8 can also be opened and closed inwardly and outwardly, and the inclination angle changes inwardly and outwardly, allowing it to be opened and closed inwardly and outwardly. Further, by replacing the replacement coating plate 9 with one having a wider or narrower V-shaped intersection, a desired surface width can be freely obtained. In addition, if the replacement coating plate 9 is mainly used with a narrow intersection width, there is no need to separate the screw movement holes 3 on the left and right as shown in FIG. 1 and drill them in the adjustment plate 2.
The same effect can be obtained by drilling holes in the center as shown in FIG. , Also, replace the replacement painted plate fixing plates 8, 8 with the angle adjusting plate 5.
If it is attached to the lower end of the tube, it can be used on the outside with the same effect if it is attached in an inverted V-shape instead of in a V-shape as shown in FIG.

Therefore, by implementing the present invention, it is possible to quickly change the angle of the painted plate fixing plate by simply tightening/loosening/replacing the screws.
This is a truly convenient invention that allows adjustment of the surface width and eliminates the need to prepare several types of surface cutting trowels depending on the surface to be finished.

Claims (1)

[Claims] 1 Fix adjustment plates in the shape of an inverted T in the vertical direction to both ends of the handle, and drill screw movement holes in the horizontal direction in an approximately elliptical shape in the horizontal plates of the adjustment plates. A fan-shaped angle adjustment plate is provided with the upper and lower ends facing inward, and an angle adjustment hole bored in the upper half parallel to the outer peripheral curved surface intersects with the screw movement hole so as to slide in the vertical direction, Attach a replacement coating plate fixing plate with an 8-shaped cross section to the lower end of the angle adjustment plate in a direction parallel to the handle, fit the replacement coating plate with a V-shaped cross section into the replacement coating plate fixing plate, and insert the replacement coating plate into the screw movement hole and the angle adjustment hole. Insert a screw for tightening and fixing, and adjust the angle of the replacement coating plate fixing plate by moving the angle adjustment plate up and down along the left and right opposing curves, and adjust the surface width by replacing the replacement coating plate with the replacement coating plate fixing plate.
