The invention relates to the technical field of medical apparatuses and instruments, and provides a limb traction device which comprises a traction seat used for fixing a limb of a patient and provided with a mounting via hole and a rotating hole, and the rotating hole and the mounting via hole are arranged at an interval and communicate through a mounting window; the basic shaft is arranged in the mounting through hole in a penetrating manner and is provided with a rack extending in the axial direction of the basic shaft; the driving mechanism comprises a rotating shaft rotationally connected into the rotating hole, a driving gear fixed to the rotating shaft and a clutch locking mechanism arranged on the rotating shaft; the driving gear is positioned in the rotating hole and is meshed with the rack through the mounting window; the clutch locking mechanism is matched with the traction seat, has a locking state and an unlocking state, and is provided with a driving end for receiving driving force; in the locking state, the clutch locking mechanism is in limiting fit with the traction seat to limit rotation of the rotating shaft; when the driving end receives driving force, the clutch locking mechanism and the traction seat are separated from limiting fit to be switched to an unlocking state, so that the rotating shaft drives the driving gear to rotate, and the traction seat is driven to slide along the basic shaft.

This utility model relates to the field of scanning equipment technology, and in particular to a quick-change battery compartment structure. The technical solution includes a scanner body and a locking block connected to the bottom of the scanner body. A battery slot is provided at one end of the scanner body near the locking block, and a battery is installed inside the battery slot. It also includes a slot at the end of the scanner body near the locking block, and a locking groove is provided inside the slot. This utility model utilizes the cooperation of a positioning pin, a locking head, a button, and a spring. When installing the battery, the battery is placed in the battery slot of the scanner body, the positioning pin of the locking block is inserted into the positioning groove, and pressing causes the locking head to engage with the slot, thus securing the battery. When replacing the battery, the button is pressed against a hard object to disengage the locking head from the slot, and then both hands can be used to separate the scanner body and the locking block, allowing the old battery to be removed or placed in. No special tools are required during the process, making the operation simple and quick, greatly simplifying the steps and reducing the skill requirement.
