A spindle drive tool for adjusting a position of a head of a spindle relative to a piston of an electro-mechanical automatic lubrication system in which the spindle and piston are connected by complementary screw threads includes a mounting portion and a coupling portion connected to the mounting portion. The mounting portion includes a bearing surface having a spindle head inlet at a first end, a first cavity and a second cavity. The spindle head inlet opens into the first cavity, the first cavity has a cross section configured to couple with the spindle head such that the spindle head cannot rotate relative to the mounting portion while in the first cavity, and the second cavity is coaxially with the first cavity and has a larger cross section than the first cavity such that the spindle head can rotate freely in the second cavity.

A screwdriver allows a screwing operation and an unscrewing operation to be performed smoothly. A screwdriver includes a housing, a motor including a stator and a rotor, a spindle, a clutch assembly, and a spindle locking assembly. The spindle includes a rod to which a tip tool is attachable, and is supported by the housing in a manner movable between an advanced position and a retracted position in a front-rear direction. The spindle has a reception hole extending frontward from a rear end face of the spindle. The clutch assembly transmits a rotational force from the rotor to the spindle in response to the spindle moving to the retracted position during forward rotation of the rotor. The spindle locking assembly transmits a rotational force from the rotor to the spindle during reverse rotation of the rotor, and includes the reception hole, and a countershaft placed in the reception hole.
