The utility model relates to the technical field of medical care, in particular to a supporting auxiliary protection frame which comprises a clamping plate, a replacement plate is arranged at the bottom of the clamping plate, an installation sliding block is fixedly connected to the top of the replacement plate, a limiting rod is slidably connected into the clamping plate, and a fixing screw rod is in threaded connection with the top of the replacement plate. According to the supporting auxiliary protection frame, through the arrangement of the clamping plate, the replacement plate, the mounting sliding block, a limiting rod, a fixing screw rod, an adjusting screw rod and a limiting ring, when the supporting auxiliary protection frame is used, the mounting sliding block is attached to a sliding groove in the bottom of the clamping plate, the replacement plate and the clamping plate are connected after attachment, and the replacement plate and the clamping plate are connected more stably by rotating the fixing screw rod; and then the adjusting screw rod is rotated to drive the bottom replacement plate to move up and down, meanwhile, the limiting rod limits the bottom replacement plate, the limiting ring is rotated after the bottom replacement plate is adjusted to a proper position, position deviation of the bottom replacement plate is prevented, and the effect of improving the adaptability of the device is achieved.

The application discloses a liquid metal bearing for an X-ray tube and the X-ray tube, relates to the technical field of X-ray tubes, and solves the technical problems of short service life and poor heat dissipation effect of the bearing. The liquid metal supporting bearing comprises a bearing sleeve, a mandrel, liquid metal and a microporous structure; the bearing sleeve is sleeved outside the mandrel, and a gap is arranged between the bearing sleeve and the mandrel; the liquid metal is filled in the gap; the microporous structure is arranged on the inner surfaces opposite to each other of the bearing sleeve and the mandrel and / or the outer surfaces opposite to each other of the mandrel and the bearing sleeve, the microporous structure is formed by a plurality of micropores arranged in an array, and the microporous structure has a protruding direction consistent with the flowing direction of the liquid metal. The liquid metal distribution is optimized through the micropores and optional microslit structures between the bearing sleeve and the mandrel, the friction coefficient is reduced, the heat dissipation performance is enhanced, and the service life and the heat dissipation effect of the bearing can be remarkably improved.

The invention discloses an unmanned aerial vehicle charging interface piece, a charging plug and a charging system, and belongs to the technical field of charging of unmanned aerial vehicles. The unmanned aerial vehicle charging interface piece comprises a battery connecting part and a charging interface part, the charging interface part comprises a plurality of interface contacts and a concave area, the interface contacts are located in the concave area, the concave area is connected with an unmanned aerial vehicle charging plug, and the cross section of the concave area is gradually increased in the direction gradually away from the battery connecting part. Therefore, the side surface area of the recessed area is increased, the contact area between the recessed area and the unmanned aerial vehicle charging plug is increased, the friction force between the recessed area and the unmanned aerial vehicle charging plug is increased, and the unmanned aerial vehicle charging interface piece and the unmanned aerial vehicle charging plug are connected more tightly. The side surface of the recessed area also has good guiding and limiting effects, so that the unmanned aerial vehicle charging plug can be well connected with a plurality of interface contacts of the recessed area, and the problem of poor charging contact is improved.

The utility model relates to the technical field of cutting tools, in particular to a flat-angle margin microbit capable of stably guiding chips, which comprises a drill edge and a drill handle, a connecting part is arranged between the drill edge and the drill handle, the drill edge comprises an inner core and a margin, and the margin is spirally distributed on the outer wall of the inner core. The edge position of the cross section of the edge strip extends outwards to form a right-trapezoid-shaped flat-angle protrusion, the inner core comprises a drill tip and a drill tail, the edge strip extends from the drill tip to the drill tail to form a first chip guide groove and a second chip guide groove, and the first chip guide groove and the second chip guide groove converge to form a third chip guide groove. The side face area of the drill edge is increased through the flat-angle protrusions, the first chip guiding grooves and the second chip guiding grooves are combined to form the third chip guiding grooves to reduce the length of the edge belt spacing part between the chip guiding grooves, and therefore the rigidity of the drill bit is improved, and when the edge belts rotate, trapezoidal slopes on the flat-angle protrusions make contact with a workpiece to be machined for guiding cutting. The cutting capacity of the drill is improved.
