BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a preferred embodiment of the present invention, in which a fixing part 1 for fixing a plaster iron handle a in a detachable manner is provided. A pivot pin bolt 2 is erected on the base, and a base 3 ′ of the rotation fixing body 3 is pivotally connected to the pivot pin bolt 2 to fix the other part 3 ″ of the rotation fixing body 3 so as to be horizontally rotatable. A shaft attachment part 4 is provided on the other part 3 ″ of the rotation fixed body 3, and the base 5 ′ of the rotation mounting body 5 is mounted on the bearing part 4, and the other end of the rotation mounting body 5 is vertically rotated. Fasten as possible,
At the other end of the rotary mounting member 5, there is provided a mounting portion 6 which can removably fasten the base end portion b 'of the long operating rod b which can be extended and contracted.

In the illustrated embodiment, the fixing portion 1 is formed in a short pipe shape to be fitted on the outer diameter of the cylindrical plaster iron handle a, and a nut is welded to the outer peripheral wall of the fixing portion 1, and the nut is attached to the nut. Fix the fixed part 1 with the plastering iron handle a
Fasten and fix to.

A bolt-shaped pivot pin bolt 2 is erected on the outer peripheral wall of the fixed portion 1, and a base 3 ′ of a female screw cylindrical rotating fixed body 3 is screwed to the pivot pin bolt 2. "to fasten the by welding, the other part 3" other part 3 of the sector plate shape to 3 'drilled pin holes 3 ₁ as pivotally mounted portion 4 at the base near the lower end of a right side of the pin hole 3 ₁ And fix the nut by welding. Reference numeral 9 in the drawing denotes a fastening wing bolt for rotating the other portion 3 "of the rotating fixed body 3 in the horizontal direction about the pivoting pin bolt 2 and fixing it to the pivoting pin bolt 2 at a desired rotational angle. It is.

The illustrated rotary mounting portion 5 and mounting portion 6 will be described.

In the illustrated mounting portion 6, a nut is welded to the outer peripheral wall surface of the short pipe shape into which the base end portion b 'of the long and extendable operating rod b is fitted, and the operating rod retaining wing bolt 10 is screwed to this nut. To fix the mounting portion 6 to the base end b 'of the operating rod b.

[0013] rotatable attachment 5 bent by concatenating short guide plate 5 ₂ long rotating mounting plate 5 ₁ and vertical設長of the vertical設長of the inverted U-shaped lower end of the mounting portion 6 and vertically, and the rotation mounting plate 5 _1, fitted the upper portion of the other part 3 of the rotation fixing member 3 "between the guide plates 5 _2, the engagement pin to the lower end of the pivot mounting plate 5 ₁ drilled holes 5 _3, the shaft attaching portion 4 by axial wearing a pin hole 3 ₁ of the pivot mounting body 5 and the engagement pin hole 5 ₃ in the axial Chakucho bolt 11
Configure, operating lever b other end shaft attaching portion 4 rotates the mounting plate 5 ₁ and the axis of the guide plates 5 ₂ as a guide provided to be vertically rotated.

[0014] Reference numeral 13 is a nut which is welded fixed to the rotating mounting plate 5 _1, the rotating mounting plate 5 ₁ When 14 became to a desired angle and the other end to the upper and lower rotation of the operation lever b It is a fixed wing bolt that is fixed to the rotation fixing portion 3 and maintains a predetermined angle.

Since the present embodiment is constructed as described above, when the fixing portion 1 is fitted to the handle a of the plastering iron and fixed by the handle fixing wing bolt 8, the axis of the handle a of the plastering iron is used. By rotating the fixing portion 1 back and forth with respect to the (X-axis), it is possible to fix the fixing portion 1 at a desired angle with respect to the X-axis, and to rotate and fix with respect to the axis (Z-axis) of the pivot pin bolt 2. By rotating the body 3 horizontally, it is possible to fix the body 3 at a desired angle with respect to the z-axis.
Can be fixed at a desired angle with respect to the Y-axis by pivoting up and down.When applying cement or plaster in a narrow place where people can not easily reach or a work site where it is hard to reach. The plastering work can be freely performed by fixing the plastering iron surface of the plastering iron to an easy-to-use angle suitable for the situation at the work site.

Further, the pivot pin bolt 2 and the base 3 'of the rotation fixing body 3 are formed in a screw structure, and this screw connection is further fixed by the fixing wing bolt 9, so that both are firmly fixed. Fixed to Similarly, since the rotation fixing body 3 and the rotation mounting portion 5 are screwed and fixed with the pivoting wing bolts 11 and the connection between the two is firmly fastened with the fixing wing bolts 14, it can be freely used during the work. Troubles such as loosening of the fittings and retightening are eliminated.

Further, as shown in the figure, in order to hold the plaster iron handle a, a detent insertion groove 1 'is provided on the lower surface of the fixing portion 1 to be inserted into the handle holding rod a' standing upright from the iron surface. The fixing part 1 of the universal fitting may be prevented from rotating against the plastering iron handle a.

[0018]

Since the embodiment of the present invention is configured as described above, when applying cement or stucco coating in a narrow place where people cannot easily reach or a work site where it is difficult to reach, the fixing part of the universal fitting is used. Is rotated back and forth with respect to the axis of the plastering iron handle, the rotation fixing body is pivoted horizontally with the axis of the pivot pin bolt, and the rotation mounting body is rotated with respect to the axis of the shaft attachment portion. The plastering iron can be rotated freely and fixed at an easy-to-use angle suitable for the work site to perform plastering work such as cement or plaster application. Easy to apply coating work such as, and can show excellent effect of saving labor cost and shortening delivery time. Freely connect practical and inexpensive plastering iron handle and base end of operating rod Metal fittings.
