A driving tool is provided with a driver for driving out a fastener from a nozzle, a balancer, and a balancer biasing member for biasing the balancer in a direction away from the nozzle. The balancer moves in the direction away from the nozzle by a biasing force of the balancer biasing member when the driver moves toward the nozzle.

Driving tool with reaction absorbing mechanism

In an electric driving tool of the invention, when moving a driverhaving driven out a fastener upwardly from a bottom dead center position and making the driverto stop at a wait position, a wait position when a decrease of a residual quantity of connected fasteners in the magazineis detected is set to be lower than a wait position when the decrease of a residual quantity of connected fasteners in the magazineis not detected.

Electric driving tool having drive mechanism controller

A pneumatic tool includes a tool body, a nose part for ejecting a nail, which is provided in a lower part of the tool body, an air chamber for storing compressed air, which is provided in the tool body, an air supply pipe for supplying the compressed air from an air supply source to the air chamber, an air duster, an air duster pipeline connected to an air outlet of the air duster, and an air duster valve for controlling supply of the compressed air to the air duster pipeline.

Pneumatic tool

A ratchet member, which is provide with a slopefor guiding a tip end of a nail inclined to a rear side of an ejection openinginto the ejection openingsand, and a guide surfacefor guiding the tip end of a nail to the center of each of the ejection openingsand, is provided on a rear side of ejection openingsandand urged so that a guide surfaceof the ratchet memberenters the ejection openingsand

Nailing drive guide mechanism for nailing machine

A nailing machine is provided with a nailing machine bodyin which a contact armis arranged so as to slide along a nose portion, and a plurality of contact noses() having different inside diameters. The contact noses() can be mounted to and dismounted from a lower end of the contact arm, and nails having different diameters can be used by exchanging the contact noses(). The inside diameter of the nose portionis so formed as to fit to a large nailhaving the largest head diameter among the nails to be used. A diameter of a driveris so formed as to fit to the contact nose() for a small nailhaving the smallest head diameter. A conical pipe portionwhich is upwardly enlarged in diameter for guiding a nail tip is formed in an upper part of the contact nose(). An upper end of this conical pipe portionis so formed as to have a larger diameter than that of the nose portion

Nailing machine

A contact nose, in which an ejection openingis formed coaxially with an ejection openingof a nose portionthat guides a driver slidably, is slidably provided at an end part of the nose portionto be urged in a direction of an end portion of the ejection opening. A guide slopeadapted to guide a tip end of a nail, which is hammered out tiltingly from the ejection openingof the nose portion, into the ejection openingis formed on an upper rear side of the ejection openingof the contact nose

An approach prevention wall for preventing a head portion of a lead nail from unnecessarily approaching is protruded on a front inner wall of the nose section of the nailing machine. The nose section accommodates the lead nail of connected nails, and the connected nails are connected with a connecting member. A lower end face of the approach prevention wall is inclined, and the inclined face of the lower end face of the approach prevention wall is formed at a position where the height of the inclined face is substantially the same as that of a position where the connecting member to connect the lead nail with the next nail is cut off at the time of driving the lead nail. Otherwise, the inclined face of the lower end face of the approach prevention wall is formed at a position where its height is higher than that.

Structure of guiding nail in nose section of nailing machine

A contact mechanism includes a contact top disposed on an outer peripheral portion of a leading end portion of a nose in such a manner that it is slidable along an axial direction of the nose, and a hollow nose top held by the contact top and including an ejection opening formed in front of an ejection opening formed in the nose in such a manner that the ejection opening of the nose top is connected continuously with the ejection opening of the nose. The contact top is connected to an adjuster mechanism through a contact arm and, at the same time, the contact top can be guided by the outer peripheral surface of the leading end portion of the nose.
