This utility model relates to a composite insulation board cutting device, including an operating platform, a track, a limiting slide plate, a cutting drive unit, a circular saw, and a movable frame. The operating platform has a cutting strip hole. The track and the limiting slide plate are both horizontally fixed below the operating platform and are arranged parallel to the cutting strip hole. The cutting drive unit is mounted on the movable frame, and its drive end is connected to the circular saw. A portion of the circular saw extends upward from the cutting strip hole and is located above the operating platform. The movable frame has a first roller and a second roller. The first roller is rotatably connected to the track, and the second roller is rotatably connected to the bottom surface of the limiting slide plate along the length of the track. At least one side of the movable frame is also fixed with an operating handle, the height of which is not lower than the height of the operating platform. This utility model is simple and labor-saving to operate, and allows for convenient adjustment of the cutting speed at any time.

This application relates to the field of storage tool technology and provides a card holder. The card holder includes a first clamping body and a second clamping body. The first clamping body is a flexible component, and the second clamping body is a rigid component. The first and second clamping bodies are connected, and a clamping space for holding cards is provided between them. The second clamping body in this application is a rigid component. This structural design provides stable structural support for the card holder, enabling it to withstand greater external forces without easily deforming, breaking, or snapping. This effectively enhances the overall durability of the card holder, reduces the risk of damage due to long-term use, and extends the card holder's service life. Simultaneously, the first and second clamping bodies, as flexible components, work together to buffer and absorb shocks when subjected to external forces, protecting the cards within the clamping space. Furthermore, the combined use of the first and second clamping bodies also makes the card holder's style less monotonous, achieving an effective fusion of two different materials.
