Abstract: A lock device is disclosed, which includes: a holder which is provided with a through hole running through the holder and a slide intersecting with the through hole; a guide bar, which is provided with an outer threaded area on at least a portion of a surface and passes through the through hole, and the outer threaded area is located where the through hole intersects with the slide; a lock component received in the slide, and the end of the lock component facing toward the guide bar is provided with a lock threaded area which can engage with the outer threaded area of the guide bar; and a drive assembly which drives a lock assembly to move toward or away from the guide bar in the slide. The guide bar is locked when threads on the lock threaded area engage with outer threads on the outer threaded area.

Abstract: A puncture needle holder comprising a base frame, a link bar, a first seat part, a second seat part, and a positioning mechanism is disclosed.

Abstract: Various embodiments disclose a shielded or isolated heat dissipating system comprising a case, a heat sink base, and a circuit board comprising at least one electronic device for which heat dissipation is desired. The heat sink base is attached to the case and together with the shielding case defines an enclosed space within which electromagnetic interference is reduced. Both heat-dissipation function and electromagnetic shielding function may be achieved by the combination of the heatsink base and the case while maintain electrical isolation with one or more specially treated components. The space required for mounting the system may also be reduced without adversely affecting normal and stable operation of the electronic device.
