Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a roof tile cutter, and more particularly to a technique for improving operability for cutting.

[Prior Art] Conventionally, in the roof tile cutter, as shown in FIG.
Only the cutting portion 2 at the tip is slidably contacted along the cutting ruler 3 to form a cutting line, and the roof tile is folded along the cutting line to cut.

[Problems to be solved by the invention] However, in order to engrave a cutting line by sliding only the cutting portion 2 at the tip of the roof tile cutter to the cutting ruler 3 as described above,
The hand is pulled while setting the angle formed by the cutting portion 2 and the roof tile 5 to an angle suitable for cutting, but the rear end of the roof tile cutter cannot be fixed, and it is difficult to maintain the optimum angle for cutting. Moreover, there was a problem that it was difficult to obtain linearity.

The present invention has been made in view of such a problem, and its purpose is to position the rear end of the cutter body and maintain the angle between the roof tile and the cutting portion at the optimum angle for cutting. The purpose of the present invention is to provide a roof tile cutter that can improve the workability of cutting and easily produce linearity.

[Means for Solving the Problems] In the roof tile cutter of the present invention, a cutting part 2 for slidingly moving a cutting ruler 3 is formed at the tip of the cutter body 1, and a cutting ruler 3 is provided at the rear end of the cutter body 1. The upper surface 3a and the side end surface 3b continuous with the upper surface 3a, the L-shaped contact surface 4 is formed, and the L-shaped contact surface 4 is formed in a flat shape, and the hanging piece 11 is provided at the rear end of the cutter body 1. A vertical surface portion of the L-shaped abutment surface 4 that is provided and contacts the side end surface 3b of the cutting ruler 3 is formed, and the rear end edge of the hanging piece 11 is inclined downward to the front side. is there.

[Operation] As described above, the cutting ruler 3 is attached to the rear end of the cutter body 1.
By forming an L-shaped abutment surface 4 capable of abutting on the upper surface 3a of the blade and the side end surface 3b continuous with the upper surface 3a of the cutter body 1, the rear end of the cutter body 1 has an upper surface 3a of the cutting ruler 3 at the L-shaped contact surface 4. Also, the rear end portion is positioned by abutting against the side end surface 3b so that a predetermined cutting angle can be maintained during cutting, and linearity can be easily obtained so that cutting can be performed with good operability. Further, since the L-shaped contact surface 4 is formed flat, the contact area of the L-shaped contact surface 4 with the upper surface 3a and the side end surface 3b of the cutting ruler 3 can be increased, and the cutter body for the cutting ruler 3 can be increased. The position and the holding of the rear end of the cutter body 1 can be surely performed, and therefore, the cutter body 1 is less likely to be shaken, and the cutting portion 2 of the cutter body 1 can be surely positioned and held. Is something that can be done. Moreover, a hanging piece 11 is provided at the rear end of the cutter body 1 to form a vertical surface portion of the L-shaped abutment surface 4 that abuts against the side end surface 3b of the cutting ruler 3 and the rear end edge of the hanging piece 11 is located at the lower front side. Since it is inclined to, the hooking of the rear edge of the hanging piece 11 can be reduced, and the hanging piece 11 can be smoothly slid when sliding along the cutting ruler 3. .

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

A cemented carbide cutting tip 7 is attached to the tip of the cutter body 1 formed with a grip 6 such as synthetic resin, and a blade holder 8 made of tool steel.
A cutting portion 2 attached by brazing or the like is formed.
An L-shaped contact surface 4 is formed at the rear end of the grip 6, and the upper surface 3a of the cutting ruler 3 and the side end surface 3b continuous with the upper surface 3a.
It can be brought into contact with. When forming the L-shaped abutment surface 4, the hanging piece 11 depending from the grip 6 may be made of tool steel, or may be made of the same synthetic resin as the grip 6.

In this way, the cutting ruler 3 is attached to the rear end of the cutter body 1.
By forming an L-shaped abutment surface 4 capable of abutting on the upper surface 3a of the blade and the side end surface 3b continuous thereto, the rear end of the cutter body 1 has a cutting ruler 3 at the L-shaped abutment surface 4.
The upper end 3a and the side end face 3b of the blade are brought into contact with each other to position the rear end, and the cutting angle formed by the roof tile 5 and the cemented carbide cutting tip 7 can be held at a substantially optimum angle, and linearity can be easily obtained for easy pulling. ,
Predetermined cutting can be performed with good operability. Further, the lower surface of the rear end portion of the cutter body 1 forming the lateral surface portion of the L-shaped contact surface 4, and the hanging piece 11 forming the vertical surface portion of the L-shaped contact surface 4.
By making each side surface of the L-shaped contact surface flat, the contact area of the lateral surface portion of the L-shaped contact surface 4 with the upper surface 3a of the cutting ruler 3 and the cutting are more effective than forming the L-shaped contact surface 4 in a curved shape. The contact area of the vertical surface portion of the L-shaped contact surface 4 with the side end surface 3b of the ruler 3 can be increased, and the rear end of the cutter body 1 with respect to the cutting ruler 3 can be positioned and held reliably. You can Also, by tilting the rear end edge of the hanging piece 11 to the lower front side, it is possible to reduce the catching of the rear end edge of the hanging piece 11. A rubber portion 9 is formed at the front end portion and the rear end portion of the grip 6. The shape and size of the grip 6 can be modified in various ways.
As shown in the figure, if a large gap 10 is formed between the grip 6 and the roof tile 5, the hand can be easily gripped.

[Effects of the Invention] In summary, according to the present invention, the rear end of the cutter body is formed with the L-shaped abutment surface capable of contacting the upper surface of the cutting ruler and the side end surface continuous with the ruler. The rear end of the L-shaped contact surface contacts the upper surface and the side end surface of the cutting ruler to position the rear end, and the optimum cutting angle can be maintained, and linearity can be easily achieved. There is an advantage that cutting can be performed with good performance. Further, since the L-shaped contact surface is formed flat, the contact area of the L-shaped contact surface with the upper surface and the side end surface of the cutting ruler can be increased, and the rear end of the cutter body is positioned with respect to the cutting ruler. In addition, the cutter body is less likely to be shaken, and the cutting portion of the cutter body can be positioned and held reliably. Moreover, since a hanging piece is provided at the rear end of the cutter body to form a vertical surface portion of the L-shaped abutment surface that abuts against the side end surface of the cutting ruler, the rear end edge of the hanging piece is inclined downward to the front side. The hook of the trailing edge of the hanging piece can be reduced, and the hanging piece can be slid smoothly when sliding along the cutting ruler.
