The present invention provides an impact tool. The hammer drill (1) is constructed to include: a cylindrical top tool holding component (10) that holds a top tool (T); a piston (16) that moves forward and backward with the rotation of a motor (4); an impact piece (18) that moves forward and backward in conjunction with the piston; an intermediate piece (20) that is housed between the impact piece and the top tool in a manner that allows it to move forward and backward in the top tool holding component, and that abuts against the rear end of the top tool during normal impact to indirectly transmit the impact from the impact piece to the top tool, and two metal front rings (42) and rear rings (43) are housed on the front side of the intermediate piece in the top tool holding component and between the top tool holding component and the intermediate piece so as to be movable in the forward and backward directions. According to the present invention, even a tool that restricts the movement of the intermediate piece toward the impact piece can exert a stable anti-air strike function.

This invention relates to the field of touch detection circuit technology, and more particularly to a high-sensitivity touch detection circuit, comprising: a touch analog circuit, a touch digital circuit, and a CPU processor. The touch digital circuit includes a counter circuit, a latch circuit, a subtractor circuit, and a comparator circuit. This invention uses a simple digital detection circuit to detect touch events and reduces false alarms or missed detections by comparing with a configured threshold, making the touch detection circuit more reliable and meeting the higher requirements of next-generation MCUs for touch detection. It can be applied in MCU systems, suitable for 32-bit and 8-bit MCU series products. Charge is transferred from on-chip I / O capacitors to on-chip capacitors. When a touch action occurs, the capacitance for charge transfer increases, leading to a decrease in the number of transfers. The digital circuit determines whether a touch event has occurred by detecting the number of transfers.
