This utility model discloses an insect-attracting and killing device, including a cylindrical lamp holder. The bottom end of the lamp holder is connected to a circular push-pull plate. An electric telescopic rod is inserted inside the lamp holder. The head end of the electric telescopic rod is fixedly connected to the push-pull plate, and the tail end of the electric telescopic rod is fixedly connected to the top of the inner cavity of a protective shell. An insect-attracting lamp tube is fixedly installed around the lamp holder, and a cylindrical electric grid cover is fitted over the lamp tube. The bottom of the protective shell has an open end, on which a ring-shaped fixing seat is installed. A cylindrical scraper is installed inside the fixing seat, and the scraper is slidably connected to the electric grid cover. This utility model can automatically store the insect-attracting lamp tube and the electric grid cover into the inner cavity of the protective shell, effectively preventing rainwater erosion and improving durability. It can also automatically scrape off insect carcasses and other impurities on the outer surface of the electric grid cover, ensuring the electric shock effect of the electric grid cover.

The utility model belongs to the technical field of police apparatuses, especially relates to a stainless steel flail, including handle, front cylinder, telescopic link and electric shock subassembly. The front cylinder is internally provided with a front movable passageway. The telescopic link includes telescopic front link and telescopic rear link. The electric shock subassembly includes battery and electric shock strip. The stainless steel flail provided in the application adopts arc conductive rubber material, can be adaptively fitted according to the shape of human body surface, increases the contact area, and the increase of the contact area can make the current more evenly distributed on the human body surface, thereby improving the electric shock effect; a plurality of electric shock strips are uniformly arranged in the telescopic rear link in a ring shape, when the current passes through these electric shock strips, can produce electric shock effect on the suspect in a larger range, makes the electric shock effect more comprehensive and effective, and is more favorable for the police to control the suspect.

The utility model relates to the technical field of electric water heaters, and discloses an electricity guard device and an electric water heater. The electricity-proof wall device comprises a shell, a sleeve and a foaming unit, a main water outlet is formed in one end of the shell, a water outlet pipe is integrally formed at one end of the main water outlet, a first flow channel is formed in the water outlet pipe, and the first flow channel communicates with the main water outlet; one end of the sleeve is closed, the other end of the sleeve is open, the sleeve detachably sleeves the water outlet pipe, a second flow channel is formed between the outer wall of the sleeve and the inner wall of the shell, a third flow channel is arranged between the inner wall of the sleeve and the outer wall of the water outlet pipe, and the third flow channel communicates with the second flow channel and the first flow channel; the bubbling unit is detachably installed in the shell, and a bubbling outlet of the bubbling unit communicates with an inlet of the second flow channel. According to the utility model, the electricity-proof effect can be improved, and meanwhile, the bubble water function is realized.

The utility model discloses a tool for fastening a hexagon nut in a limited space. The tool comprises a handle, a connecting rod, a nut and an end which are connected in sequence, the handle adopts a DN20 galvanized tee joint design, so that when a hexagon nut which is difficult to disassemble or fasten is encountered, other tools can be used for penetrating through the tee joint to increase the torque, and the work can be more effectively completed; the internal thread connection is adopted, so that the stability and reliability of the connection are ensured, and the tool is not easy to loosen or damage in the use process; the insulating tape is wound outside, so that not only are the insulating and anti-electric shock effects achieved, but also the friction force is increased, and a user is safer and more stable in the operation process; meanwhile, the insulated rubber tape also has anti-corrosion and anti-rust functions, so that the service life of the tool can be prolonged.
