This invention discloses a prefabricated steel formwork device for concrete encapsulation of drainage pipe socket interfaces, belonging to the field of drainage pipe network construction technology. The device includes a modular steel formwork body customized to the pipe dimensions, pins, manual fixing screws, pin fixing holes, a rear handle, an installation handle, and multiple sets of fixing holes. The pins and fixing holes are located at the junction of the steel formwork body. The manual fixing screws are installed in the pin fixing holes. Multiple sets of handles are located on both sides and the rear of the steel formwork body, and the fixing holes are evenly distributed on the sides and rear of the formwork. During construction, the modular formwork is snapped onto the pipe socket interface, the pins are aligned and positioned, and the screws are tightened to form a whole. Steel rods are inserted through the fixing holes for fixation, and concrete is poured to complete the encapsulation. This invention offers quick installation, precise positioning, firm fixation, and resistance to bulging and deformation, resulting in high-quality concrete molding. It is also easy to disassemble and can be reused multiple times, significantly reducing construction costs and improving work efficiency.

The present application relates to the technical field of plasma cutting, in particular to a positioning cutting device for processing luggage hardware, which comprises a machine tool, the top of the machine tool is fixedly connected with slide rail one and slide rail two, the slide rail one is slidably connected with slide block one, the slide rail two is slidably connected with slide block two, the slide block one is slidably connected with mounting column, and the mounting column is slidably connected with plasma cutting mechanism on one side. The present application realizes the composite functions of blanking, positioning, clamping and other stages by moving the inclined surface sliding block by different distances and cooperating with path switching. The inner expansion type clamping provides a perfect working space without obstruction for the plasma cutting mechanism, ensures the integrity and flexibility of cutting, and through the inner expansion clamping at one end and the end top shaft at the other end, a stable two-end support is formed for the metal rod, and the stable rotation is driven by the driving shaft, effectively resisting the vibration generated during plasma cutting, ensuring the stability of the cutting process, thereby ensuring the high quality and high precision of the cut.

The utility model relates to a pet excrement receiving device, which comprises a handle and an elastic telescopic rod installed at one end of the handle, and the elastic telescopic rod is hingedly connected with an excrement receiving claw at the tail end; when the elastic telescopic rod is extended under the action of elastic force, the excrement receiving claw is automatically elastically opened to clamp a garbage bag and receive pet excrement; when not in use, the excrement receiving claw can be stored on the elastic telescopic rod in the folded state to realize compact folding and portable storage. The utility model has the advantages of simple structure, convenient operation, quick deployment of the excrement receiving structure, improved efficiency of cleaning pet excrement outside, and good practical value and portability.

The utility model provides a kind of motor clutch device of dynamic load adjustment, including motor, transmission mechanism, controller and clutch mechanism. Clutch mechanism is made of ratchet wheel and paddle, is located on transmission path. When motor positive rotation, paddle is disconnected with ratchet wheel, load is separated from power, realizes artificial free pay-off without resistance;When motor reverses, paddle is embedded in ratchet wheel tooth groove, power transmission is to drum, realizes constant speed automatic pay-off. Transmission mechanism adopts small sprocket, chain, large sprocket and coaxial drum structure, realizes deceleration and torque increase. Ratchet wheel is one-way bevel gear, ensure one-way locking. The device is equipped with inductive switch and controller cooperation, automatically detects clutch state and executes safety start-stop logic, ensure reliable engagement before reversing. Compact overall structure, response is reliable, without additional power element, applicable to agricultural pesticide spraying, cable laying and other need flexible feeding and automatic recovery scene, significantly improve operation convenience and safety.
