Safety bench saw provided with annular sawblade

Abstract

The invention belongs to the technical field of bench saw, and particularly relates to a safety bench saw provided with an annular sawblade. The safety bench saw provided with the annular sawblade comprises a bench saw housing, a controller, the annular sawblade, a motor, a driving wheel, a first U-shaped plate, a first swinging rod, an arc-shaped guide rail, a telescoping rod, a belt, a driven wheel, etc., wherein after explosive is ignited and combusted, the first swinging rod and a second swinging rod instantaneously move far away from a triangular block, and a first shaft sleeve drives a ring sleeve to move toward the triangular block after transmission; after a first limiting tooth and a second limiting tooth perform limiting, the annular sawblade is instantaneously stopped rotating;the annular sawblade instantaneously completely enters a mechanism chamber under the double effects of instantaneous moving of the ring sleeve in the the triangular block direction and kinetic drivingof the annular sawblade, and thus the risk that hands are injured due to further touch the annular sawblade can be reduced; in addition, the belt is gradually loosened while the driven wheel instantaneously moves in the triangular block direction, so that the possibility that the annular sawblade is driven to rotate through the driven wheel after transmission, and as a result, the safety of a user is protected.

Description

technical field [0001] The invention belongs to the technical field of table saws, in particular to a safety table saw with a circular saw blade. 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 ang...

[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
