Abstract: A protective device of a power tool includes a fixing base having a tube portion and an abutting surface, a restricting ring fitting around the tube portion, several springs disposed between the abutting surface and a first end of the restricting ring, a protective cover having several second projections and several second recesses, and a locking member. The first end has an abutting portion. A second end of the restricting ring has several first projections and several first recesses matching with the second projections and the second recesses. The restricting ring is located between the protective cover and the abutting surface. When a blocking portion of the locking member moves to a first position, the blocking portion restricts the restricting ring from moving toward the abutting surface. When the blocking portion moves to a second position, the blocking portion leaves a position between the abutting surface and the abutting portion.

Abstract: An impact tool having an exchangeable handle structure includes an impact tool main body. A rear-end portion of the impact tool main body forms an engaging portion having two lugs respectively on a top surface and a bottom surface and an annular body on a rear-end surface. Two penetrated portions respectively extend from a top side and a bottom side of the annular body. A left-half part and a right-half part of a front-end portion of a casing cover the lugs and the annular body. A plurality of fixing members respectively passes through the lugs, arm casings formed by the casing, the penetrated portions, and a rear annular casing of the casing. The rear annular casing is connected to a handle having a triggering member. The impact tool main body is detachably engaged with a handle device through the engaging portion.

Abstract: A motor assembly includes a motor in a housing. The motor includes a stator and a rotor mounted in the stator casing, and an output shaft engaged with the rotor passes through the stator casing. Two opposite ends of the stator casing and the stator abuts against an annular plate and a rear end cap, respectively. Each screw passes through the rear end cap and the stator to screw into the annular plate, so the stator is fixed and restricted from moving axially in the stator casing. A front end of the housing is engaged with a motor fixing frame. The output shaft passes through a bearing on the motor fixing frame. The motor fixing frame is spaced from the motor. With such design, a vibration of the output shaft during operation is transmitted to the housing, but not directly affect the screws in the motor, thereby increasing the durability of the motor assembly.

Abstract: A mandrel collector includes a case body and an end plate. The case body has a connecting end for being connected to a rivet gun. The end plate is engaged with the case body and is opposite to the connecting end. The end plate has at least one receiving hole, wherein a hole section of the receiving hole is a hexagonal hole with six walls. The walls include three first walls and three second walls. Each of the first walls is connected between adjacent two of the second walls. The hole section is defined to have a central axis and a reference plane perpendicular to the central axis. On the reference plane, a side length of at least one of the first walls is smaller than side lengths of the second walls. With such design, the receiving hole could receive a head of an adapter and could rotate the adapter as a screwdriver.
