Safety bench saw

Abstract

The invention belongs to the technical field of bench saws, and particularly relates to a safety bench saw. The safety bench saw comprises a bench saw shell, a controller, an annular saw blade, a motor, a driving wheel, a first U-shaped plate, a first swing rod, an arc-shaped guide rail, a telescopic rod, a belt, a driven wheel and the like, wherein the first swing rod and the second swing rod instantly move towards the direction away from a triangular block after gunpowder is triggered to be exploded, and a first shaft sleeve drives a ring sleeve to move to the triangular block instantly after being transmitted; after limiting of first limiting teeth and second limiting teeth, the annular saw blade stops rotating at the moment; under the dual action of instantaneous moving of the ring sleeve to the triangular block and driving of the angular momentum of the annular saw blade, the annular saw blade completely enters a mechanism cavity instantly so that the damage risk caused by furthercontact with the annular saw blade to hands can be reduced. In addition, when the driven wheel moves to the triangular block instantly, the belt is gradually loosened, so that the possibility that the annular saw blade rotates after transmission of the driven wheel is avoided, and the safety of a user is better protected.

Description

technical field [0001] The invention belongs to the technical field of table saws, in particular to a safety table saw. Background technique [0002] At present, for the traditional table saw, the user needs to use the table saw carefully to cut the object to be cut; however, in the process of using the table saw, the hand of the user may still be cut due to accidents. In order to prevent the user from being cut by accident, there is a hot dog saw in the current technology that is specially designed to protect the user, but the saw blade of the hot dog saw cuts in a very short time In the process of stopping, the saw blade is limited instantly by rigidity; when the saw blade is stopped rapidly by rigid limit many times, the teeth on the saw blade are easily damaged by the collision of rigid limit; at the same time, the traditional hot dog saw The way for the saw blade to return to the table below the saw table in an emergency is realized by the angular momentum of the saw b...

[0002] At present, for the traditional table saw, the user needs to be careful to use the table saw to cut the object to be cut; but in the process of using it, the user may still cut his hand due to accidents

In order to prevent the user from being cut by accident, there is a hot dog saw in the current technology that is specially designed to protect the user, but the saw blade of the hot dog saw cuts in a very short time In the process of stopping, the saw blade is limited instantly by rigidity; when the saw blade is stopped rapidly by rigid limit many times, the teeth on the saw blade are easily damaged by the collision of rigid limit; at the same time, the traditional hot dog saw The way for the saw blade to return to the table below the saw table in an emergency is realized by the angular momentum of the saw blade; the reliability of the mechanism operation can be guaranteed by increasing the way the saw blade returns to the table below the saw table; In addition, in order to prevent the saw blade from being damaged by the rigid limit collision, it is necessary to design a safety table saw that can protect the saw blade
