The invention discloses a folding and variable stiffness instrument arm for natural orifice surgery. The instrument arm is a surgical support tool with variable scale and variable rigidity, including a braided tube structure and a sealing membrane, and the sealing membrane includes The inner and outer sides and ends of the braided tube structure are covered to form an annular closed inner cavity, and the braided tube structure is covered inside it. The diameter of the instrument arm can be increased through the airbag or the driving wire, and the gas in the sealing membrane can be extracted to make the braided tube appear rigid and large-diameter, providing a larger passage for subsequent surgical tools, preventing subsequent tools from poking tissue, and providing Supports guarantee precision. It can also restore the soft state by re-entering the gas in the sealing film, and use the elasticity of the braided tube structure to return to the small-diameter state, so that the arm of the device can be more easily extended into and out of the human body cavity, and avoid puncture injuries and reduce human discomfort. .

A telescopic packaging and weighing system used for a silane crosslinking cable material production line comprises a hopper, a telescopic rotary support used for supporting packaging bags, and a metering device. The central point of the hopper, the central point of the support and the center point of the metering device are all located on a straight line perpendicular to the horizontal plane. The support is composed of two frames. The two frames are connected through connecting pieces which are arranged at the central point of the upper border and the central point of the lower border. The frames can rotate clockwise or anticlockwise, and an included angle between the two frames ranges from 0 degree to 360 degrees. The frames can be pulled upwards and downwards according to requirements so that the length of the left border and the right border can be adjusted. The frames are connected with a fixed sliding groove through a sliding rod. The sliding rod is connected with the fixed sliding groove through a rotatable connecting piece. A rail used for the sliding rod to slide is arranged on the fixed sliding groove. The telescopic packaging and weighing system has the beneficial effects that the packaging efficiency can be improved, and cargo bagging and weighing are facilitated.

The invention discloses a telescopic tool for machining a large-diameter inner hole by a numerical control lathe, and belongs to the field of mechanical machining devices. The telescopic tool comprises a tool bit (1) and a front tool apron (2) and is characterized by further comprising a rectangular rear tool apron (3), an adjusting nut (4), an adjusting rod (5), a joint bearing (8) and an adjusting seat (9), a large boss and a small boss are formed at the right end of the front tool apron (2), a through hole of the rear tool apron and a through hole in the large boss of the front tool apron (2) are mounted in a matched manner through a pin (6), an outer circle of the joint bearing (8) is fixed at the right end of the rear tool apron (3), an inner circle of the joint bearing is fixed with the adjusting nut (4), the right end of the adjusting rod (5) is connected with the adjusting nut (4), the left end of the adjusting rod (5) is fixed on the adjusting seat (9), and a through hole of the adjusting seat (9) and a through hole in the small boss of the front tool apron (2) are mounted in a matched manner through the pin (6). According to the telescopic tool, the tool bit can expand and contract in the hole diameter of a machining part, so that parts with narrow port sizes and large hole sizes are machined.

The invention discloses a quick demoulding terminal machine suitable for automatic processing, which includes a frame and a terminal die installed in the frame, the terminal die includes an upper support die and a lower support die, and the frame includes a bottom plate and a mounting Vertically placed on the bottom plate, the upper end of the vertical frame is equipped with an auxiliary clamping mounting frame, a downward pressure cylinder is installed in the auxiliary clamping mounting frame, a demoulding cylinder is installed on the bottom plate, and the downward pressure cylinder Set coaxially with the demoulding cylinder; the upper mold includes an upper mold base and a traveling cutter head connected to the upper mold base and coaxial with the driving direction of the lower pressure cylinder, and the lower mold includes a lower mold base The base and the retracting cutter head connected to the lower supporting mold base and coaxially connected to the power end of the demoulding cylinder, the advantage of the present invention is that the fixed end of the traditional terminal machine becomes a fixed lower supporting mold base and the retreating cutter head The combination, after the processing is completed, the retreating cutter head falls, which is convenient for the product to withdraw, and adapts to the automatic assembly line production mode.

The invention provides a detachable lower ball seat for a high-speed bridge swivel steel bearing, relates to the technical field of bridge construction, and solves the problem that the existing detachable lower ball seat for a bridge swivel steel bearing needs to be disassembled. It is extremely difficult to jack up the bridge first and then to be disassembled, and the bridge is jacked up and then dropped, which also makes the bridge a great safety hazard, and there may be deviations in the position, including the lower ball seat; The upper end of the lower ball seat is horizontally equipped with a lower ball joint. In the present invention, because the left end edge and the right end edge of the lower ball seat are respectively fixed with horizontal side support plates, they can also play a fixed role at the same time, and when the construction is completed, the squeeze block and self-unloading can be made The blocks are separated, so that the lower ball joint part falls, so that there is a gap between the device and the bridge, which can be withdrawn freely. In summary, the device is safer and more efficient when used, and the reuse rate is extremely high.

The invention discloses an underground movable split escape capsule system, which relates to the technical field of underground disaster prevention life-saving equipment for a coal mine and consists of a transition capsule, a main capsule and an auxiliary capsule, wherein all capsule body split bodies are connected through flanges and are provided with a transition capsule door, a main capsule door and an auxiliary capsule door. The underground movable split escape capsule system is characterized in that the system in the capsule body mainly consists of an alternating current motive-power power supply and high-capacity colloid storage battery uninterrupted conversion device, a compressed air system oxygen supply device, a compressed oxygen supply device, a filteration, temperature reduction and dehumidifying integration device, a gas dilution purifying device and an excrement collector, wherein the alternating current motive-power power supply and high-capacity colloid storage battery uninterrupted conversion device provides electric power supply for a communication and environment gas monitoring system and an instrument, and the excrement collector is arranged in the transition cabin.
