摘要:
A portable cutting tool includes a blade and a motor for driving the blade to rotate. The motor has a motor output shaft. A guard assembly includes an upper guard and a lower guard which is used for receiving the motor. A base is connected to the upper guard. The base further includes a front portion connected to the upper guard, a rear portion extending longitudinally, and a gripping portion disposed between the front portion and the rear portion. The blade shaft is perpendicular to the motor output shaft.

A method of testing a braking device in a drivetrain of a vehicle which includes at least one tractive element coupled to a traction motor. The method includes: (a) applying the braking device to a tractive element of the vehicle; (b) using an electronic controller, causing the traction motor to apply a predetermined force to the tractive element; and (c) using the controller, monitoring the tractive element for movement while the force is being applied. A dynamic braking or “retarder” function may also be tested. A system for carrying out the method is provided.

The present invention relates to a miter saw, including a base, a work table, a saw unit pivotally mounted on the base, and fence assembly connected to the base. The fence assembly is directly removably mounted on the base so as not to cause space between the two fences, thus promoting cutting precision and making simple structures at a lower cost. The fences having different heights are interchangeably used, which increases inclined cutting angles.

A power tool comprising a housing, a motor, an output shaft, a gear transmission mechanism and a control system. The gear transmission mechanism is connected between the motor and the output shaft to transmit the rotary power of the motor to the output shaft. The power tool comprises a signal generator and a control system electrically coupled to the signal generator and operatively engaged with the gear transmission mechanism such that when the signal generator is manually activated, an electric signal is generated and transmitted to the control system to cause the gear transmission mechanism to vary the gear reduction ratio.

A miter saw comprises a worktable; a first support member attached to the worktable; a second support member attached to the first support member; a saw unit pivotally connected to the second support member via a pivot; and a matching mechanism disposed between the first support member and the second support member, the matching mechanism is operated to cause the second support member to move with respect to the first support member, and the second support member is moved to reach a plurality of predetermined working positions to perform cutting operation. Thus, the cutting capacity of the miter saw is improved for the miter saw being able to cut workpieces with more specifications.

An industrial dust collector comprises a frame body, a suction device attached to the frame body, a suction device attached to the suction device. The frame body has a containing cavity for containing the suction device. A supporting device is disposed between the suction device and the frame body for the suction device being movably attached to the frame body, so that the suction device can move between an unfolding status and a containing status. In the unfolding status, the suction device is unfolded relative to the containing cavity; in the containing status, the suction device is contained in the containing cavity. Therefore, the industrial dust collector has the advantages of small packaging size, convenient transportation and low transportation cost.
