Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Embodiments of the lime cutter for troweling the inside and outside corners of the present utility model are shown in fig. 1-5.

Example 1

The lime cutter for plastering and polishing the internal and external corners of the embodiment comprises a V-shaped cutter body 1 and a handle 2, wherein the cutter body 1 is hinged with the handle 2 so as to adjust the angle between the cutter body 1 and the handle 2, and internal corner and external corner construction is convenient to conduct. The cutter body and the handle are fixed at an angle through the fixing piece. The cutter body 1 comprises two mutually perpendicular cutter plates, and the cutter body is integrally formed. The two knife boards are trapezoidal boards, and the long sides of the two knife boards are clung. The right-angle edges of the two knife boards are respectively welded with a first connecting sheet 3, the first connecting sheet 3 is a trapezoid sheet, and the bottom plates of the two first connecting sheets 3 are parallel. The handle 2 is a cylindrical handle, one end of the handle connected with the cutter body is welded with a second connecting sheet 5, the second connecting sheet 5 is positioned between the first connecting sheets 3, and the first connecting sheets clamp the second connecting sheets. The first connecting piece 3 is provided with a first circular connecting hole 4, the second connecting piece 5 is provided with a second circular connecting hole (not shown in the figure), the fixing piece is a screw 6, and the screw 6 penetrates through the first connecting piece 3 and the second connecting piece 5 so as to fix the angle between the handle 2 and the cutter body 1. The screw 6 is screwed with the first connecting hole 4 and the second connecting hole (not shown in the figure), and the screw 6 is fixed by a nut 7. After the angle between the handle and the cutter body is adjusted, the angle between the handle and the cutter body can be fixed by screwing the screw and then fixing the screw with the nut. The handle 2 is a telescopic handle so that constructors can collect light for the internal corners and the external corners of the high place. For the internal corners and the external corners at the lower part, the handle is contracted to a proper length, and after the angle between the handle and the cutter body is adjusted, the plaster cutter for plastering and light collecting at the internal and external corners is directly used for plastering and light collecting. And for the internal corners and external corners of the high place, after the plastering of constructors is finished, the handle is extended, and after the angle between the handle and the cutter body is adjusted, the lime cutter for plastering and collecting the internal and external corners can be used for collecting the internal and external corners of the high place by standing on the ground.
