The utility model discloses a variable diameter blowout preventer pipe relates to wellhead sealing blowout preventer technical field, and its technical key points include main pipeline, the top of main pipeline installs first variable diameter pipe, the top of first variable diameter pipe installs second variable diameter pipe, the top of second variable diameter pipe installs the top pipe, the utility model discloses when using, realized through variable diameter pipe group and realized the passage diameter adaptation, and pressure sensor and blowout preventer valve guarantee safety, with the help of flange, U -shaped clamping plate and locking assembly, realize quick firm connection with least three bolts, trapezoidal positioning structure realizes pipeline accurate butt joint, and the overall operation efficiency, safety and convenience are improved.

The present application relates to the technical field of plasma cutting, in particular to a positioning cutting device for processing luggage hardware, which comprises a machine tool, the top of the machine tool is fixedly connected with slide rail one and slide rail two, the slide rail one is slidably connected with slide block one, the slide rail two is slidably connected with slide block two, the slide block one is slidably connected with mounting column, and the mounting column is slidably connected with plasma cutting mechanism on one side. The present application realizes the composite functions of blanking, positioning, clamping and other stages by moving the inclined surface sliding block by different distances and cooperating with path switching. The inner expansion type clamping provides a perfect working space without obstruction for the plasma cutting mechanism, ensures the integrity and flexibility of cutting, and through the inner expansion clamping at one end and the end top shaft at the other end, a stable two-end support is formed for the metal rod, and the stable rotation is driven by the driving shaft, effectively resisting the vibration generated during plasma cutting, ensuring the stability of the cutting process, thereby ensuring the high quality and high precision of the cut.
