This utility model belongs to the field of knife sharpener technology, and in particular to a replaceable manual knife sharpener, comprising a first housing and a second housing. A detachable magnetic connector is provided between the first and second housings, and the first and second housings, when connected, form the knife sharpener housing. A mounting groove is provided at the lower end of the knife sharpener housing. A limiting plate is integrally formed on the inner surface of the lower end of the knife sharpener housing, and a magnet is adhered to the surface of the limiting plate. An iron sheet attracted by the magnetic force of the magnet is provided on the surface of the mounting groove, and a sharpening blade is adhered and fixed to the lower surface of the iron sheet. The detachable connection between the first and second housings is achieved through the magnetic connector, allowing for quick disassembly or assembly of the knife sharpener housing without the need for tools. This not only facilitates the inspection and maintenance of internal components but also reduces space occupation during storage. Compared to traditional bolt fixing, the disassembly and assembly efficiency is improved by more than 50%.

The invention relates to the technical field of film sticking machines, in particular to an elevator door plate automatic film sticking machine which comprises a support, a conveying belt assembly and a film sticking assembly, and the film sticking assembly comprises a film releasing roller, a first motor, two guide rollers, two gears, a second motor, a cleaning component, a pressing component, a supporting component and a cutting component. An elevator door plate is placed on a conveying belt assembly, a cleaning component blows the surface of the door plate, a first motor drives a film releasing roller to rotate, a protective film material is released, a second motor is started, a guide roller is driven to rotate, and film paper led out of the film releasing roller is actively pulled to be conveyed in the direction of the elevator door plate; the film paper is tightly pressed and attached to the surface of the door plate through the pressing component; the cutting component accurately cuts off the film paper along the edge of the door plate; the problems that when the door plate area is large, manual film pasting consumes time and labor, the production efficiency is low, and the protection effect and the product appearance are affected due to inaccurate alignment and many bubble wrinkles caused by manual operation are effectively solved.

This utility model relates to the field of electric forklift charging technology, and in particular to a fast charging device for electric forklifts. It includes a bracket with a vertical support rod, and a charging gun with a protective component. The protective component includes a housing fixed to the charging gun's outer shell, a dual-axis motor housed within the housing, a worm gear driven by both ends of the dual-axis motor, a worm wheel driven by the worm gear, a vertical shaft driven by the worm wheel, a horizontal connecting rod connected to the vertical shaft, and a protective cover at the end of the horizontal connecting rod. The two protective covers rotatably cover the front connector of the charging gun to protect it. By providing a protective component driven by a dual-axis motor, worm gear, and other transmission mechanisms on the charging gun, the protective cover of this component can automatically open and close, thereby achieving automatic protection of the front connector of the charging gun.
