摘要： PROBLEM TO BE SOLVED: To provide a hand tool device having simple construction for optimizing a pressure fluctuation in an impact mechanism. SOLUTION: The hand tool device comprises the pneumatic impact mechanism 20 to be driven by a motor 12. The impact mechanism 20 defines a center axis S of the impact mechanism. It has an exciting element 22 reciprocative in a guide tube 21, and an impact element 23 to be movably guided into the guide tube 21 and driven via a pneumatic spring 25 by the exciting element 22. The exciting element 22 is reciprocative with a connection rod 29 eccentrically arranged on a motor-driven eccentric wheel 17 having a fixed rotational axis D. The rotational axis D of the eccentric wheel 17 is arranged an offset distance X in a direction perpendicular to the impact axis S. Preferably, the offset distance X from the rotational axis D to the impact mechanism axis S is 10-80% of a radius RE of the eccentric wheel 17, and the connection rod 29 has a bent form.

摘要： PROBLEM TO BE SOLVED: To obtain a hammer tool apparatus achieving hammer efficiency improved from a viewpoint of ergonomics.
SOLUTION: In a pneumatic hammer mechanism including a drive section for periodically moving a floating piston 13 between a hammer surface 27 and a position closest to an excitation piston 12, if the hammer mechanism 5 has a hammer frequency f during hammer action, mass m
2 of the floating piston 13, cross-sectional area A of a pneumatic space, maximum length L of the pneumatic space, stroke H of the excitation piston 12, and reflection coefficient q satisfy the following inequality, namely the inequality 1, thereby increasing hammer energy. Hereat, the value of parameter N is at least 4; p
0 is an outside air pressure; and κ is an entropy coefficient of gas or the like within the pneumatic space.

摘要： PROBLEM TO BE SOLVED: To provide active vibration damping equipment of simple structure for a hand tool device having a pneumatic striking structure using crank mechanism transmission.
SOLUTION: The hand tool device is driven by a crank pin 4 of an eccentric element 5 rotatably supported, and mass distribution having an unbalance load center U in relation to the eccentric axis E is given, and the unbalance load center U is arranged at a position shifted from the crank pin 4, which is separated by the crank radius K, by the unbalance load angle ψ in a range at 70°-90° in the rotating direction of the crank pin. Desirably, in a zone having impact frequency at 5Hz-25 Hz, degree of unbalance to be applied to the crank radius K and mass of a floating piston is set in a rage at 0.4-1.0. The eccentric element 5 is provided with a crank plate 9, and this crank plate 9 has non-rotatable symmetrical mass distribution with an eccentric top view, and is structured into a non-specular symmetrical shape in relation to the crank radius K.

摘要： PROBLEM TO BE SOLVED: To lengthen service life and to prevent accumulation of cutting chips and dust particles by distributing blowholes in an opposite direction of the drilling direction and in a peripheral direction along a second flat surface separated in parallel by a certain distance from a first flat surface. SOLUTION: A stroking body 19 to work in cooperation with a hammer 17 is provided between a piston 7 and a first idle end of a guide cylinder 9, and the stroking body 19 is made free to move longitudinally through an air cushion between itself and the piston 7. Blowholes 10, 11 arranged between the piston 7 and the stroking body 19 and extending in the radial direction to influence on pressure of the air cushion are provided on the guide cylinder 9. The blowholes 10 are distributed along the circumference of a first flat surface E1, and the blowholes 11 are distributed along a second flat surface E2 with an interval in an opposite direction of the drilling direction from the first flat surface E1. Control of the blowholes 10 and the blowholes 11 is carried out by a control body, and the control body is made free to move in the drilling direction by the hammer 17 and a spring 12 on the opposite side of the drilling direction against the guide cylinder 9.
