Auxiliary tool guaranteeing linear machining performed by carpenter

The invention discloses an auxiliary tool guaranteeing linear machining performed by a carpenter. The auxiliary tool guaranteeing linear machining performed by the carpenter comprises a machining table which is provided with an electric lifting table; the table face of the electric lifting table is provided with two parallel grooves; each groove is internally provided with two suspended rollers; the highest point of the rollers is higher than the surface of the electric lifting table; the rollers are connected to the inner walls of the grooves through roller shafts; the electric lifting table is provided with a sliding plate; the bottom of the sliding plate is provided with two parallel sliding grooves; the two sliding grooves are right opposite to the two grooves correspondingly; the sliding grooves are matched with the rollers; and the machining table is further provided with an F-shaped hand screw clamp. The auxiliary tool guaranteeing linear machining performed by the carpenter aims at solving the problems that when the carpenter uses an electric drill to drill holes in the prior art, handholding is not stable, the hole drilling quality is affected, and potential safety hazards exist due to direct contact with the electric drill, and the purposes of reducing the potential safety hazards and meanwhile keeping straight hole drilling are achieved.
