Abstract: A cover of a power battery has a plate, two electrodes, and two sealing pieces. The plate has two through holes disposed on the plate. The two electrodes are respectively engaged with the plate. The two sealing pieces are respectively mounted between the two electrodes and the plate, and are located between the two electrodes and the two through holes. Furthermore, the two sealing pieces are each formed integrally by an injection-molding step. The two sealing pieces allow the cover to isolate the outer space and the inner space of the power battery, and further to avoid air or liquid leakage. Moreover, the injection molding simplifies the assembly of the cover of a power battery, which makes the process of producing a cover of a power battery more efficient and more convenient. A manufacturing method of the cover of a power battery is also provided.

Abstract: A boot insole includes a sole base and multiple absorbing studs. The sole base is a flat pad that matches a foot contour and has multiple air vents. The absorbing studs are integrally and downwardly formed on a bottom surface of the sole base. The boot insole provides a shock absorbing effect without adding an air cushion to decrease the pressure on the foot, and also increases the ventilation between the foot sole and the orthopedic boot.

The holder extender is pivotally combined with the ankle holder and located over the ankle holder. The four combination structures are disposed on the base, the ankle holder, and the holder extender to combine with the base, the ankle holder, and the holder extender. The ankle stirrup can achieve a fixing effect for an ankle of a user.

Abstract: An ankle stirrup has an ankle holder, a positioning unit, and multiple mounting belts. The ankle holder has a leg portion comprising a hole formed through the leg portion, and a foot portion. The positioning unit is mounted in the hole of the ankle holder, and has a body being elongated and having a longitudinal direction and a rotatable portion formed on a front side of the body, inserted through, engaging, and being rotatable relative to the hole. The positioning unit further has a limiting portion detachably mounted in the rotatable portion to keep the rotatable portion from detaching from the hole.

Abstract: A length adjusting device has a guiding track and a controlling assembly. The guiding track has a guiding structure and a locking structure. The controlling assembly has a connecting base, an engaging body, a switch base, a spring, a switch, and a controlling body. The guiding track is mounted between the connecting base and the engaging body. The engaging body is selectively engaged with the guiding track. The switch is combined with the connecting base and has a switching recess. The spring is mounted between and compressed by the engaging body and the switch base. The switch is selectively engaged in the switching recess. The controlling body is mounted on the switch base and has a gear engaged with the guiding track.

Abstract: An adjustable limb protective assembly has a main body, a first covering frame and a second covering frame. The main body has a first extending arm, a second extending arm, two holding bases, two operating elements and a jointing connector. Each extending arm has a connecting board. The holding bases are respectively connected to the extending arms adjacent the connecting boards. The operating elements are respectively and securely mounted on the connecting boards, and each one of the operating elements has an operating mount and an operating stem. The jointing connector is connected to the extending arms. The first covering frame is connected to the first extending arm and has a first supporting arm and a first covering base. The second covering frame is connected to the second extending arm and has a second supporting arm and a second covering base.

Abstract: A rehabilitation footwear has a sole, two supporting arms and multiple fastening belts. The sole has two sidewalls formed on and protrude from a top of the sole and facing to each other. The supporting arms are respectively connected to the sidewalls of the sole and each has an inserting tab, multiple supporting tabs, at least two bending segments and multiple belt mounts. The inserting tab is connected to one of the sidewalls of the sole. The supporting tabs are sequentially formed with each other. The at least two bending segments are formed with the supporting tabs, and each bending segment is formed with two adjacent supporting tabs and has a convex inner side and a concave outer side. The belt mounts are respectively mounted on the supporting mounts. The fastening belts are connected to the sole and the supporting arms.

Abstract: A buckle of a seat belt has a seat belt buckle body, a releasing button module, a spring module, and a buckle module. The releasing button module is pivotally mounted in the seat belt buckle body and has a spring recess and an abutted portion. The spring module has a buckle spring mounted in the spring recess and a buckle spring block mounted on the buckle spring. The buckle module engages the releasing button module, and abuts the buckle spring block. When the releasing button module is pressed and the buckle module disengages from the releasing button module, the buckle spring will spring the buckle spring block, the buckle module will depart from the seat belt buckle body, and then the buckle spring block is stopped on the abutted portion. As a result, the buckle spring will not spring out of the seat belt buckle body.
