The invention relates to a small fishing gear for fishing, in particular to a fishing device with a tension spring capable of automatically contracting to enable the fish to get hooked and not to fall off at the moment when the fish swallowed bait during fishing, and the fishing device is composed of the tension spring, a shell pipe, a protection line, a boss, a buoy, a sub-line, a fishhook and the like, and is named as a tension spring type automatic fishhook.

This application discloses a worm-inspired robot based on shape memory alloy and magnetic field, belonging to the field of soft robot technology. It not only shortens the contraction cycle and improves work efficiency but also achieves free steering and expands its application range. The robot includes at least one main structure; the main structure includes a bellows, a telescopic column structure, two magnet plates, two fixing rings, and multiple helical shape memory alloy wires; each end of the bellows is connected to a magnet plate via a fixing ring, and the two magnet plates are arranged facing each other with the same poles; the middle of the helical shape memory alloy wires passes through the bellows, and both ends are connected to corresponding fixing rings, with multiple helical shape memory alloy wires evenly distributed along the circumference of the bellows; the helical shape memory alloy wires contract and return to their helical state when energized; the telescopic column structure is located inside the bellows, and its two ends can provide different levels of resistance to the robot, thereby assisting the robot in moving forward or turning.

A kind of high-strength aluminum alloy special-shaped shell member hot straightening device and preparation method, steps: calculate the size of aluminum alloy raw material bar, carry out blanking;Preheated blank is carried out single die forging extrusion near net forming, after forging rapid cooling;Solution treatment and cryogenic treatment;After cryogenic treatment, special-shaped shell member is carried out precision hot straightening, carries out aging treatment.The hot straightening device is mainly composed of low-expansion high-thermal-conductivity high-silicon aluminum-based composite material mold, micron-sized high-silicon aluminum alloy filling particles, heating tooling and ultrasonic generator, the solid-phase particles in the shell are under the combined action of thermal field and ultrasonic field, realize the precision hot straightening of aluminum alloy shell near final size.The present application adopts the composite heat treatment method of forging rapid cooling-solution quenching-cryogenic treatment-precision hot straightening+aging strengthening treatment, effectively improves the mechanical properties and dimensional stability of aluminum alloy special-shaped shell member, has the advantages of high component bearing capacity, high material utilization rate, low cost, strong equipment versatility and the like.
