The clutch can automatically function to let the drive wheel of an electric tool engage or disengage from the driven wheel in driving a screw to a preset depth in an object, able to prevent both the drive wheel and the driven wheel from wearing.

Abstract: A bit holder includes a shank, and a bit sleeve. The shank has a first end portion of a non-circular geometric equiangular cross-section for combining a hand tool, and a second end portion formed with a combining hole having female threads in its wall. The bit sleeve has a through hole for a bit to extend therein, male threads and a circular circumference. The bit sleeve is combined with the shank by engagement of the male threads with the female threads, and the bit sleeve may be rotated to fix with or loosen from the shank by an auxiliary tool for changing the bit. In assembling, the bit is inserted through the through hole of the bit sleeve, and then the male threads of the bit sleeve are engaged with the female threads of the shank by an auxiliary tool fitted with the circular circumference and rotated to keep the bit combined with the shank, with the bit sleeve pressing the bit so as to minimize the tolerance of the gap between them, thus enabling the bit to drive a screw smoothly into an object.

Abstract: An adjustable drilling edge-widening and screw driving tool set includes a main body, a first sleeve, a second sleeve and a third sleeve. The main body has the front portion installed with a drill base and the rear portion combined with a locking rod of a powered tool. With the powered tool to drive the main body to rotate, the drill base fixing a drill can be simultaneously driven to rotate. A first sleeve combined with a second sleeve is used to operate a micro adjustment of extending length of the drill base and the drill to get a precise depth of drilling and edge-widening, and a third sleeve is employed to enable the locking rod combined with or released from the rear portion of main body. The locking rod released from the main body can be solely used as a screw driver. So, the adjustable tool set has three kinds of functions.

Abstract: A self-drilling screw includes a thread section, a head on the thread section, and a drilling section. The thread section has plural threads. The drilling section includes two opposite cutting edges with an end point for cutting a hole in a workpiece, a discharging section for exhausting bits cut by the drilling section, a guiding section formed above the discharging section to lead the screw to vertically move in the workpiece, and two discharging grooves to lead cut bits to temporarily stay in the discharging section. When the screw is rotated to move in a workpiece, the cutting edges can drill a hole, with cut bits moving into the discharge section and exhausted out through the discharging grooves. After the screw moves into the workpiece for a certain depth, the guiding section can guide the screw to move straight and accurately in the workpiece.

Abstract: A torque releasing clutch for a screw driver blade is installed in a connect rod, including a spring, ball holes for fitting steel balls, and a washer respectively in the holes to restrict the spring and the steel balls within the groove of the clutch so that the clutch moves forward and backward regularly. When a screw is driven in an object for a preset depth, the clutch may push forward the screw driver blade so that the torque-releasing steel balls may release the screw driver blade in time. Then, even if the screw driver should still have some torque, it might only rotate the connect rod idly, keeping the driver blade immovable. Thus the remaining torque might not damage the blade slot of the screw, in addition to avoiding the remaining torque returning to a user of the screw driver and harming the user.
