Abstract

Provided is an auxiliary device that can easily and uniformly cut without the need for skilled techniques.
A side plate 2 is formed at right angles to the left and right of a bottom plate 1 of a support base. The side plate has a hole 3 serving as a bearing, and an inner shaft can be moved in an arc shape on an arc centered on the hole 3. A slot 4 is provided. The hole 3 and the groove hole 4 are provided at positions facing the left and right side plates of the support base, and a guide plate 5 is sandwiched therebetween. A rotation shaft 8 is attached to the guide plate 5 through the hole 3 of the side plate 2, and the guide plate 5 can rotate about the rotation shaft 8 by the length of the slot 4 provided in the side plate 2. It is like that. Further, a fixing knob 7 that can be screwed is attached to the guide plate 5 through the slot 4 of the side plate 2. The guide plate 5 can be maintained at an optimum cutting angle by loosening the fixing knob 7 and moving the guide plate 5 to an angle at which it is desired to cut the molded product and tightening the fixing knob 7.

Description

      The present invention cuts the end face of a plate-shaped molded product (hereinafter referred to as a molded product) such as a thick soft resin or paper that can be cut with a cutter knife, etc. It is for cutting the end face uniformly at a set angle so as to be flat, and is used as an auxiliary tool that can easily perform uniform cutting without requiring a skilled technique.

      Construction works such as moldings and thick wallpaper on floors and walls are frequently carried out at construction sites and interior construction sites, but the floor and wall areas rarely coincide with molded products. Therefore, it becomes necessary to cut the molded product according to the shape of the wall or floor. The molded product has a wall thickness, and it is not always necessary to cut the end faces vertically when joining, and it is necessary to cut diagonally. In such a case, the operator makes sure that the direction does not go wrong with a ruler, a plate, etc., but the angle to cut is determined by the scale, and the work is supported by hand so that the angle of the cutter knife does not go wrong. Yes. However, it was difficult to cut straight while keeping the angle unless it was very skilled, and there was a demand for a tool that could be easily operated on site.

      If the cutter knife is supported by a ruler or a plate and the angle is determined, and the end face of the molded product is cut obliquely, the blade of the cutter knife will inevitably shake, creating irregularities on the cut surface, and the cutting angle will not be fixed. It takes skill to do exactly. I want to be able to do this easily even if I am not an expert.

      A guide plate made of spacers inserted at both ends to create a space between the two side plates and the blade of the cutter knife between them, and a guide that can freely adjust the angle of the guide plate with respect to the cut surface The problem can be solved by using a combination of plate supports.

When the blade of the cutter knife is inserted into the slot provided in the guide plate of the present invention and the molded product is cut, even if the blade of the cutter knife is shaken by the repulsive force of the object, the guide plates on both sides are shaken. In order to hold down, it was possible to cut linearly and the cut surface became flat.
The angle adjustment function provided on the guide plate support can freely adjust the angle of the guide plate with respect to the molded product. Now anyone can do it easily.

      The present invention will be described with reference to FIGS. FIG. 1 is an overall configuration diagram of the present invention, and FIG. 2 is a rotating shaft of a guide plate and a fixing knob. There are side plates 2 that rise up at right angles to the left and right of the bottom plate 1 of the support base in FIG. 1, and the side plate has a hole 3 that can be a bearing and a groove that can move the shaft in an arc on the arc centered on the hole 3. A hole 4 is provided. The hole 3 and the groove hole 4 are provided at positions facing the left and right side plates of the support base, and a guide plate 5 is sandwiched therebetween. A rotation shaft 8 is attached to the guide plate 5 through the hole 3 of the side plate 2, and the guide plate 5 can rotate about the rotation shaft 8 by the length of the slot 4 provided in the side plate 2. It is like that. Further, a fixing knob 7 that can be screwed is attached to the guide plate 5 through the slot 4 of the side plate 2. The guide plate 5 can be maintained at an optimum cutting angle by loosening the fixing knob 7 and moving the guide plate 5 to an angle at which it is desired to cut the molded product and tightening the fixing knob 7. A more accurate angle can be set by carving a scale indicating the angle in the slot.

      The guide plate 5 is provided with a guide groove hole 6 into which a blade of a cutter knife fits exactly and can move the blade of the cutter knife in the horizontal direction. When cutting the molded product, insert the blade of the cutter knife into one end of the guide slot 6 of the guide plate 5 fixed at a fixed angle so that the blade penetrates the molded product, and move the cutter knife toward the other end. The molded product is cut at a set angle without the blade of the cutter knife being shaken.

      Since the cutter knife guide of the present invention is easy to operate and is portable, it can be easily used at any construction site. In addition, the work time can be shortened without requiring skill, and the finished state can be satisfied. In the future, cutting work of a molded product at a construction site will be performed, and the convenience of the present invention is always required there.

  1 is an overall view of the present invention.   It is a rotating shaft and a fixed knob used in the present invention.

Claims (1)

    It is possible to freely set the angle at which the end face of the object is cut. Insert the blade of the cutter knife into the groove that is open to the thickness of the blade and slide it sideways along the groove, so that it is below the bottom plate. A cutter knife guide intended to cut the end face of a fixed object at a predetermined angle so that the cut surface is evenly flat.
