Abstract: The present invention relates to the technical field of power-driven hammers, and more specifically, to an impact structure, which comprises a connecting shaft with two ends connected to first bearings and second bearings, wherein the shaft is sleeved around a control disc whose one end-face is connected to gears and the other end-face connected to a striking disc having keys along its circumference, a first stop ring around the shaft and a second stop ring around the shaft are provided respectively between the control disc and the first bearings and between the striking disc and the second bearings, and a spring is provided between the second stop ring and the striking disc; the present invention reciprocates by meshing between the control disc's driving teeth and the striking disc's driven teeth and under the spring's action in operation, effectively avoiding being stuck fast to ensure uninterrupted striking of nails.

Abstract: A locking device for a spindle of an electric tool comprises an output shaft, a fixing ring, a retainer, locking roller pins, bearing roller pins and a power output disc. When the power output disc is active, the power output disc drives the output shaft to rotate thus outputting torque and meanwhile driving the retainer to rotate synchronously; when the output shaft is active, the output shaft rotates to make the planes of the multi-surface shaft of the output shaft deflect and drives the locking roller pins to abut against the fixing ring so as to lock the spindle. In the locking process, under the supporting effect of the bearing roller pins, the spindle rotates in a balanced mode and is stressed uniformly, the locking reliability is high, and the overall structure assembling difficulty is low.

Abstract: Disclosed is a gear adjusting device for a gearbox of an impact drill, comprising a front gearbox housing, a torsional cover, a reduction mechanism and a tripping mechanism which comprises annular adjusting screws, tripping columns and a tripping cushion. Each tripping column is sleeved with a compression spring with two ends respectively connected to the bottom of a corresponding adjusting screw and a corresponding tripping column. The torsional cover is in threaded drive connection with each adjusting screw. The lower end of each tripping column is connected with the reduction mechanism. The tripping cushion is slidably connected to the front gearbox housing along the vertical direction. A cushion locking structure is disposed between the torsional cover and the front gearbox housing. The tripping cushion can be locked and fixed by the cushion locking structure when the torsional cover is rotated anticlockwise, and then the tripping cushion cannot move vertically.

Abstract: A self-locking device of an electric tool output shaft includes a main shaft, a power output disk, a stop ring, and a plurality of self-locking pins. An upper end surface of the power output disk is provided with a plurality of drive blocks. A bottom of the main shaft is inserted into the power output disk. An inner side of the power output disk is provided with a plurality of drive surfaces. An outer wall of a lower end of the main shaft is provided with a plurality of driven surfaces and a plurality of self-locking surfaces. The main shaft has the driven surfaces to lean against the drive surfaces and the power output disk to accomplish a power output function, and further has the self-locking surfaces to lean against the self-locking pins to accomplish a self-locking function.

Abstract: A gear adjusting device for an electric impact device, comprising a front gearbox housing, a torsional cover rotationally sleeved at the top of the front gearbox housing, a reduction mechanism disposed at the bottom of the front gearbox housing and a tripping structure disposed within the torsional cover. The tripping structure consists of an adjusting screw, a tripping cushion, an adjusting ring and an impact conversion cushion. The adjusting ring can lock the tripping cushion and the impact conversion cushion. The torsional cover and the adjusting ring are provided with corresponding upper bosses and lower bosses, so the torsional cover drives the adjusting ring to rotate during anticlockwise rotation and when the torsional cover rotates clockwise, the adjusting ring does not rotate. Therefore, gear switching can be conducted when the torsional cover is rotated anticlockwise, achieving the effects of short adjustment stroke and quick switching.

Abstract: An impact switching device of an impact drill gearbox includes a gearbox front shell, an output shaft, a torque regulating mechanism, an impact mechanism, a decelerating mechanism and a gear shifting mechanism. The gearbox front shell on its top is prominently mounted with threaded columns. The gear shifting mechanism includes a function switching loop, a circular adjustment screw, a gear shifting gasket and stop posts. The adjustment screw is in thread connection to the threaded columns. The stop posts are connected to the gearbox front shell. The lower ends of the stop posts are connected with the decelerating mechanism. The gear shifting gasket is slidingly connected to the gearbox front shell along the vertical direction. The upper end face of the gear shifting gasket is prominently provided with position-limiting bosses.

Abstract: A system and method of updating firmware and a method of creating firmware are provided. The system includes a firmware storage module having first firmware and second firmware. The first and second firmware each have image header file data, including a cyclic redundancy checksum (CRC) and an image header file creation time. The method of updating firmware includes determining whether the first and second firmware have an abnormality according to the CRC information. When an abnormality is present in the first or second firmware, the abnormality-stricken firmware is replaced with new firmware. When the abnormality is absent from the first and second firmware, the first firmware is compared with the second firmware in terms of the image header file creation time such that the firmware with the earlier creation time is replaced by the new firmware. Operable firmware is available even if the firmware updating operation fails.
