This utility model discloses a lifting device for PT connecting sleeves, relating to the field of installation equipment technology. The lifting device for PT connecting sleeves includes a base and a hanger located in the middle of the top surface of the base. It also includes a slider slidably connected to the top left side of the hanger, with a fixing mechanism fixedly connected to the bottom of the slider. Through the fixing mechanism, when the device is to be used, the external PT connecting sleeve is first passed through a suspension rope, and then secured using the rope loops and fixing buckles inside the suspension rope. Next, the lifting hydraulic rod is raised, allowing the sleeve to rise with the fixing plate for further transportation. This facilitates the securing and lifting of the connecting sleeve during transportation, preventing tilting and detachment during transport due to inadequate or insufficient securing, which reduces transportation efficiency and increases the damage rate of the connecting sleeve.

This invention provides a guidewire clamping device, aiming to solve the problems of the clamping range being limited by the metal nozzle and the risk of guidewire clamping damage in existing guidewire clamping devices. This invention mainly includes a handle and a cap. One end of the handle, inserted into the cap, integrates a bite-shaped cavity for clamping the guidewire. Because the handle of this guidewire clamping device integrates a bite-shaped cavity with existing functions, compared to the metal nozzle of existing standard parts, its internal bite-clamping range is fixed, thus limiting its ability to clamp the guidewire. The bite-shaped cavity integrated in the guidewire clamping device provided by this invention consists of four bite-shaped flaps, resulting in a simpler structure, reducing the assembly difficulty of existing products. Furthermore, the handle is made entirely of nylon PA material, preventing damage to the guidewire body.
