Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a guide piece KII for a portable small electric light.

Traditionally, portable electric circular saws have been used to cut various types of wood according to the capabilities of the main body, but in recent years, portable electric circular saws in particular have been used as hand saws for various types of wood processing. ing. In the above-mentioned processing, it often happens that paper cutting is started halfway through the wood.In this case, a guide piece 3 indicating the cutting position of the saw blade 2 of the small portable electric circular saw 1ki shown in the figure is attached to the main body. 4 is fixed by protruding from the surface plate 5 in the front direction of the papermaking process, so when cutting starts halfway through the wood 6, as shown in Figure 2, the guide piece 3 serves as a fulcrum and the main body 4 moves from side to side (Figure 2). The saw blade 2 is not positioned at the desired cutting position 7, making it difficult to process the wood 6.The portable large W11E circular saw shown in FIG.
The guide piece 8 is located inside the surface plate 9, and the defects shown above have been removed, but the processing line 1o shown on the wood 6
A portion 11 of the machine was hidden under the surface plate 90, and the machine was inferior to a small portable electric circular saw in terms of confirming the cutting position.

An object of the present invention is to eliminate the drawbacks of the conventional guide pieces of a small portable electric circular saw and a guide piece of a large portable electric circular saw, and to improve the operability of the portable electric circular saw.

The present invention has a structure in which the guide piece is movable relative to the surface plate, and when a load is applied to the guide piece, the guide piece enters the surface plate, and when the load is removed, the guide piece is automatically returned by a spring. be.

[Specific examples are shown in Figures 4 to 5. As shown in Figure IIJ, the guide piece 12 passes through a square hole 14 provided in a surface plate 15, and is capable of protruding and sinking into the surface plate, and is fixed to the surface plate with screws 15. The threaded portion forms an elongated hole 16 to enable the guide piece to move relative to the surface plate. Furthermore, the spring 17 is made to correspond to the convex portion 18 of the guide piece,
The guide piece is buried so that a restoring force is applied during running.

The spring is fixed with a pin 19 provided on the surface plate.

In such a configuration, the operation is shown in FIG.

When starting cutting with the portable electric circular saw 20 along the cutting line halfway through the wood 6, aligning the guide piece 12 to the position of the cutting line will reduce the weight of the portable electric circular saw and the cutting line. The guide piece receives a load in the direction of the arrow mark 22 due to the operating force of the circular saw, and is applied to the inside of the surface plate 13. After the guide piece is buried, cutting is started using the tip 23 of the surface plate as a fulcrum, and cutting is performed in a stable state. Furthermore, the surface plate is connected to the wood and the bottom part 2.
When the entire surface contacts in step 4, the load on the guide piece is removed and the guide piece protrudes from the tip of the surface plate due to the return force of the spring as shown in Fig. 4, and the position of the guide piece and the machining line is confirmed. You can cut while cutting.

According to the present invention, in a portable electric circular saw, the guide piece can be protruded from and buried in the surface plate, so that stable cutting is possible when cutting from the middle of the wood, and the portable electric circular saw can be operated. I was able to improve my sexuality. Furthermore, since it has an automatic return structure, the load on the guide piece is removed, and when it cools down, the guide piece moves to the center of the round surface from the surface plate, so that it does not interfere with the next cutting operation.
