The first to fourth links are arranged in a parallelogram configuration, wherein the first and third links are arranged on opposite sides and the second and fourth joints are arranged in a diagonal direction. The front link extends from the first link. The first extension link is rotatably connected to the second joint. The second extension link is rotatably connected to the first extension joint. The third extension link is rotatably connected to the second extension joint. The fourth extension link is arranged between the third extension joint and the fourth extension joint. The fifth extension link is arranged between the first joint and the second extension joint. The first, fourth, and fifth extension links are in parallel with one another.

A frame lifting mechanism includes a base, a motor, a lead screw, a sliding member, a lifting member and a supporting shaft. The motor is connected to the lead screw, and the lead screw is fastened onto a transmission tube, allowing the transmission tube to move forward and backward while being driven by the lead screw. The sliding member is installed on a sliding track arranged on the base and connected to the transmission tube, allowing the sliding base to actuate with the transmission tube synchronously. A rear end of the lifting base is pivotally attached onto the base for support, and the supporting member uses its two top and bottom ends to be pivotally attached onto the lifting member and the sliding member respectively, allowing the supporting shaft to utilize the movement of the sliding member to drive the lifting member to move upward and downward.

A trajectory record arm is disclosed, on which the connection apparatus is engaged in order to provide the transmission of the motion trajectory of a connection apparatus to a trajectory recording device. The trajectory record arm includes: at least one telescopic bar which is engaged on one side with at least one fastening element and on the other side with the connection apparatus such that freedom of rotation is allowed between the fastening element and the connection apparatus, at least one first sensor for detecting the movement between the telescopic bar and the fastening element, at least one second sensor for detecting the distance change between the fastening element and the connection apparatus based on the change in the length of the telescopic bar, at least one third sensor for detecting the movement of the connection apparatus in relation with the telescopic bar.

The present invention provides a motor shell, comprising a hollow metal shaft and a plastic shell, wherein the hollow metal shaft is fixedly connected to the plastic shell, and the connection between the hollow metal shaft and the plastic shell is one of injection molding connection, glue connection and interference connection. By using the motor shell according to the present invention, problems in the prior art such as low processing precision of the motor shaft, poor wiring structure, low structural strength, no limiting for the magnetic ring and tending to deform after loading are solved.

A reusable flexible arm stabilizes tissues during surgical procedures. The stabilizer arm switches between a flexible state for conforming to a desired curvature and a rigid state for maintain a desired positioning. A suspension length provided by the stabilizer arm is also adjustable. The arm has an articulating portion with successive articulating links each having a central passage. A length adjustable portion has successive length-adjustable links each having a central passage. A tension cable extends through the central passages between a proximal one of the length-adjustable links and a distal one of the articulating links. A base member captures the length-adjustable links at a position corresponding to a desired extension length of the arm. A control mechanism is movable between a retracted position and an extended position to selectably separate the captured length-adjustable links, thereby adjusting a tension in the tension cable and a rigidity of the stabilizer arm.

A rotation mechanism having a positioning function includes a rotary base, a rotary set rotatably arranged on the rotary base, a securing set mounted on the rotary set for adjusting a spacing between the rotary set and the rotary base, and an elastic set mounted between the securing set and the rotary set and butted against by the securing set for providing an elastic force. The rotary case includes a fix pin extending from the rotary base and a first slide portion portion disposed on the rotary base and configured around the fix pin. The rotary set includes a second slide portion correspondingly engaged with the first slide portion, and a first opening used for receiving the fix pin and allowing the rotary set being rotated relative to the rotary base.

This application is directed to a passively-cooled electronic device including a housing, a plurality of electronic assemblies and a plurality of thermally conductive parts. The electronic assemblies are enclosed in the housing, and include a first electronic assembly and a second electronic assembly. The first and second electronic assemblies are disposed proximately to each other within the housing, and the second electronic assembly is substantially sensitive to heat, including heat generated by operation of the first electronic assembly. The thermally conductive parts are coupled between the first electronic assembly and the housing, and configured to create a first plurality of heat conduction paths to conduct the heat generated by the first electronic assembly away from the second electronic assembly without using a fan. At least a subset of the thermally conductive parts mechanically supports one or both of the first and second electronic assemblies.

A rotary joint for a lighting fixture includes: a first mounting member having a first housing; a second mounting member having a second housing and a positioning plate; a number of first metal connecting plates fixed to the first mounting member; a number of second metal connecting plates fixed to the second mounting member; and a shaft passing through the first housing, the second housing, the positioning plate, the first metal connecting plates, and the second metal connecting plates. The shaft rotatably connects the first mounting member to the second mounting member.

A assembled support mechanism for an LED display screen, comprises: a bottom support, being in an assembled frame structure, provided with devices configured for longitudinal and transverse splicing at a periphery thereof, and the devices configured for longitudinal and transverse splicing comprising a longitudinal engagement device and a transverse engagement device; and middle portions of a front side and a rear side of the bottom support being respectively provided with screen connecting portions configured for connecting to an LED display screen in a vertical direction. A plurality of rotational stands, in detachable connection with the bottom support, and a respective rotational stand after being spliced and assembled being rotatable around the bottom support with a rotational angle range of 0° to 180°.
