The invention discloses an electric drill with the drill bit diameter being adjustable. The electric drill is composed of a machine body assembly, a clutch sliding sleeve, a hydraulic adjusting assembly and an expandable drill bit. The expandable drill bit is adopted, the thickness of the drill bit can be adjusted through the oil charging amount according to the requirements, stepless gradually varied adjustment can be achieved, the machining requirement of holes within a certain range is met, the drill bit does not needed to be replaced, the situation of infirm mounting due to frequent drill bit replacement is avoided, and the working safety is improved; an output shaft is used for providing power for the hydraulic adjusting assembly and the expandable drill bit, power switching is achieved through the clutch sliding sleeve, the adjustment difficulty of the expandable drill bit is lowered, operation is more convenient, rapid and convenient, the part utilization rate is increased to the maximum, an existing structure can still be used, the machine body assembly does not need to be modified, and machining implementation is easier.

The invention discloses a combined type trachea cannula fixing device which is composed of two parts with symmetrical structures, wherein each part includes an elastic teeth cushion used for expanding and bracing the upper jaw and the lower jaw, an adjusting sliding block used for expanding and bracing the corresponding elastic teeth cushion, and an arc hoop used for fixing a tracheal catheter; each arc hoop is connected with the corresponding adjusting sliding block through a crank arm. In clinical application, the fixing device does not cause aching pain of the teeth due to overstress or harm to the oral cavity, teeth or lips of a patient, can provide stable support for the tracheal catheter, can be applied to tracheal catheters with various specifications and sizes, and is suitable for various patients with individual difference; the fixing device is ingenious in structural design, relatively easy to manufacture and implement, low in cost, and relatively convenient to mount, dismount and adjust, and can be operated by one person.

The invention discloses an internet remote medical training or meeting system. After improvement, the system is provided with both a main display screen and an auxiliary display screen, multi-positionsynchronous display can be achieved, the main display screen can move back and forth on two main display screen movable guide rails, the best display distance is obtained after regulation, and the normal distance viewing can be achieved for all conferees; on the other hand, each set of auxiliary display screens are movably arranged inside a meeting room through stand columns, the position of eachset of auxiliary display screens is rotatable for achieving display at different angles; during operation after improvement, the conferees in the meeting room can obtain pattern information obtainedthrough remote speaking, image information of a spokesman in the meeting room can be known, the attention of the conferees is improved, and therefore the remote medical training or meeting quality isimproved.

The invention discloses an automobile transmission shaft installation and fixing structure, which comprises a transmission shaft fixing crossbeam fixed on the lower surface of the front floor, and the transmission shaft fixing crossbeam is composed of a crossbeam body and a transmission shaft fixing seat welded and fixed on the outer surface of the crossbeam body. On the upper surface of the front floor, a reinforcing crossbeam symmetrical to the fixed crossbeam of the transmission shaft is welded and fixed. The structure of the invention has better rigidity and can meet the requirements of bearing capacity and fixing reliability.

The invention discloses a deformation machining process for nickel based alloys and iron nickel based alloys, and is used for solving the technical problems that the deformation machining of the nickel based alloys and the iron nickel based alloys in a solid solution state lowers the amount of crystal boundary carbide precipitation of materials in subsequent aging or serving process, thereby reducing the endurance strength, and the nickel based alloys and the iron nickel based alloys are low in plasticity, high in strength, difficult to deform and easy to crack when being subjected to deformation machining in an aging state. The process is technically characterized in that the nickel based alloys and the iron nickel based alloys subjected to solid solution treatment are subjected to one relatively-high-temperature heat treatment, carbides are precipitated near a crystal boundary firstly and simultaneously the precipitation of intracrystalline gamma' or gamma'' phases is reduced, then the obtained objects are subjected to deformation machining until the objects reach the required shape and size of parts, and finally, the obtained products are subjected to aging treatment, so that both the process properties of materials in the stage of deformation machining are ensured, and the final endurance strength of products is ensured.

The invention discloses an anti-loosening and anti-rotation structure for threaded connection. The structure comprises a connecting outer sleeve, a connecting inner sleeve and anti-rotation reeds, wherein an inner surface of one end of the connecting outer sleeve is provided with a number of grooves that are arranged on the same circumference, the grooves are the same in structure, and each groove is provided with three arcs that are different in radius; along a clockwise screw thread engagement direction, a first arc is far greater than a third arc in radius; an outer surface of the connecting inner sleeve is provided with a number of gaps that are arranged on the same circumference, an inner part of each gap is provided with an anti-rotation reed, and each anti-rotation reed corresponds to a groove on the inner surface of the connecting outer sleeve; when a connector plug head is plugged in a plug seat, easy rotation can be realized in the presence of resistance due to a large radius of the first arc in each groove of the connecting inner sleeve and a smooth chamfer; after the plug head is screwed, great resistance of the anti-rotation reeds is met when a product operates in a vibration environment due to a small radius of the second arc in each groove of the connecting inner sleeve, and therefore a connector can be prevented from loosening and can be protected.
