Abstract: A quick-release screwdriver structure includes a tool holder and a tool head embedded in a head portion of the tool holder. A fixing seat is sleeved outside the tool head; an inner wall of the fixing seat is provided with a notch, and a bottom surface of the notch is an inclined surface; a steel ball connected to a release ring is installed in the notch, and the steel ball contacts the tool head; and a movement of the release ring will drive the steel ball to move along a longitudinal direction of the bottom surface of the notch so as to lock or release the tool head. A new locking assembly is designed to act on a surface of the tool head so as to achieve locking and disassembly of the tool head.

Abstract: A two-way ratchet screwdriver includes a handle, a main shaft acting on a working end, a ratchet seat, and a reversing seat. Two ends of the ratchet seat are provided with an upper ratchet head and a lower ratchet head, respectively. The upper ratchet head has the same structure as the lower ratchet head and is fixedly connected to the handle. The upper ratchet head is provided with a circle of wheel facing teeth and a circle of ratchet teeth. The wheel facing teeth of the upper and lower ratchet heads are connected by pinions. A periphery of the reversing seat is mounted with at least one set of a forward pawl and an inverse pawl passing through the ratchet seat. The reversing seat is switched to rotate to drive the forward pawl or inverse pawl to act on the ratchet teeth of the upper and lower ratchet heads.

Abstract: An external tooth type ratchet screwdriver includes a handle and a ratchet head, the handle is provided with a ratchet seat, a first pawl and a second pawl; the ratchet head is of a round-bar shape and passes through the center of the ratchet seat; the middle part of the outer surface of the ratchet head is provided with teeth; one end of the inner circle of the first pawl is provided with a ratchet teeth structure; the second pawl has the same structure with the first pawl; the end surface of the ratchet seat is eccentrically provided with a circle of annular groove, and one end of the annular groove is cut off, and arc-shaped barrier strips are oppositely arranged on a cutoff; installation seats are formed between the wall of the ratchet seat and the arc-shaped barrier strips; a reversing cover is clamped outside the ratchet seat.

Abstract: The present disclosure discloses an image processing method of a mobile terminal, and a mobile terminal. To process an image, an audio signal is collected using a sensor of the mobile terminal. Air-blowing signal intensity is acquired by performing a windowed fast Fourier transform (FFT) on the audio signal to obtain a frequency domain signal of the audio signal. The frequency domain signal of the audio signal is divided into at least one time-slice frequency domain signal. It is then identified whether the audio signal is an air-blowing signal according to the at least one time-slice frequency domain signal and a preset property of the air-blowing signal. The air-blowing signal intensity is acquired according to the at least one time-slice frequency domain signal when the audio signal is identified as an air-blowing signal. An image is acquired according to the air-blowing signal intensity.

Abstract: The present invention discloses an apparatus, system and method for accessing internet webpage. The system includes a user terminal and a proxy server. The user terminal is configured to initiate an access request to the proxy server, the access request including URL information of a target webpage which carries an identifier of requiring security authentication, and receive and display target webpage information outputted from the proxy server. The proxy server is configured to receive the access request, perform security authentication on the URL information of the target webpage which carries the identifier of requiring security authentication according to pre-stored webpage security database information; if the security authentication is passed, obtain the target webpage information and output the target webpage information to the user terminal. By applying the present invention, network delay overload for accessing the internet webpage can be reduced, and user experience can be improved.
