Abstract: A bit assembly includes a bit for driving a screw, a shank for holding and driving the bit to rotate about a pivot axis wherein the bit is capable of moving relative to the shank in a predetermined range, and a limiting structure formed between the bit and the shank for preventing the bit to move beyond the predetermined range. The bit and the shank are made of different materials and form a sliding connection so that they have a certain buffer space in the axial direction and in the circumferential direction thereby reducing the effect of impacts on the service life of the bit assembly.

Abstract: A screw tool having a gear head, which has a freewheel gear, having an output shaft, which is inserted in a non-rotatable but displaceable manner in an output opening and can be moved to and fro between a right-hand screw position and a left-hand screw position in each case by use of axial displacement, wherein in each case a different end section of the output shaft projects out of the gear head, having at least one locking mechanism to secure the position of the output shaft in the respective screw position and/or around a screw output element on the output shaft. As a development which is advantageous for use, the at least one locking mechanism can be moved from a locking position to a release position by pressure on an actuation element arranged on the end face of the output shaft.

Abstract: A top surface of a transmitter on a torque wrench is opposed to a position camera, and bolt holes to fix the transmitter to a wrench main body open on the top surface. The bolt holes are formed to four places so as to define a rectangle and extend in a thickness direction of the transmitter. The marker is attached to the top surface of a head of one of the bolts, which extends through a through bolt hole. When the transmitter is fixed to the main body using a bolt, the depth of a large diameter portion of the through bolt hole is larger than the total thickness of the bolt head portion and the marker. Therefore, the marker is disposed lower than an aperture surface of the bolt hole and the possibility of the marker being damaged during work is reduced.

Abstract: A two-stage locking electric screwdriver, with its main improved features as follow: the electric screwdriver has pre-locking and locking functions; the torque settings of the electric screwdriver can be easily modulated, and meanwhile the torque accuracy and energy efficiency can be improved; the torque modulation type is external modulation, so that the torque modulation can be carried out externally and even the torsion spring can be replaced. Meanwhile, the component structures inside the electric screwdriver is improved through a design that the motor directly drives the clutch and then drive the screwdriver head unit, and that an internal gear clutch is used to replaced the gear unit and clutch unit, so that the number of parts is dramatically reduced to save production cost. During general rotation, the electric screwdriver will not drive the clutch unit, and when the torque jumps to the set value, the internal gear clutch rotates and generates a torque.
