The barrel segment wallboard processing system and barrel segment wallboard processing method provided by the application comprise a workbench provided with a work guide rail, a welding unit provided on the work guide rail and provided with a first transmission mechanism, the welding unit being adapted to move along the work guide rail under the action of the first transmission mechanism and to frictionally weld stringers and skins, a milling unit provided on the work guide rail and provided with a second transmission mechanism, the milling unit being adapted to move along the work guide rail under the action of the second transmission mechanism and to mill the skins, and a clamping tool provided on the workbench and provided adjacent to the work guide rail between the welding unit and the milling unit, the clamping tool being adapted to limit the stringers and the skins. Such a design enables the stringers and the skins to be automatically welded and connected, improves the manufacturing efficiency of the storage tank, and facilitates the system to realize different processes and improve the application range due to the separate arrangement and independent movement of the welding unit and the milling unit.

The utility model relates to a fan handle, include: handle, one end of handle is connected with fan body, the outside structure of handle is established with box body mounting groove, box body mounting groove detachably with the box body of containing liquid is established, is equipped with the water inlet on the box body, the water inlet is closed through lid or rubber stopper, the connecting surface of box body with box body mounting groove is established magnet, the box body is established on box body mounting groove through magnetic attraction, the connecting surface of box body with box body mounting groove is established with magic tape, the box body is detachably fixed on box body mounting groove through magic tape, beneficial effect lies in: the box body cooling down is detachably connected on handle, and the user is convenient to cool down the box body alone, and the cooling effect is more obvious, and will not consume the electric quantity, does not influence the endurance time of fan.

The invention relates to a shunt stoma system, and belongs to the technical field of medical instruments. According to the atrial tissue cutting device, the pushing tube movably penetrates through the shunting sheath tube, the connecting rod movably penetrates through the pushing tube, the plug is connected with the connecting rod, and the cutter is arranged at the far end of the pushing tube, so that the plug and the cutter can be conveniently matched to clamp the atrial tissue to be cut, and the pushing tube can conveniently drive the cutter to rotate and move so as to cut the clamped tissue; according to the split-flow ostomy device, the cutter is arranged at the far end of the cutter, and the plug plugs the far end opening of the cutter, so that the cut tissue is plugged in a space formed by the plug and the cutter, the cut tissue can be conveniently withdrawn out of a body along with the split-flow ostomy device, and the cut tissue is prevented from being left in the atrium; the shunt stoma device in the system is reasonable in structural design and convenient to use, and cut tissue cannot fall off easily in the withdrawing process.

The utility model discloses a quick tool retracting mechanism of a boring machine in a pipeline orifice, which comprises a tool bar, a tool apron, a tool rest and a tool disc, the tool bar is fixed on the tool apron, the tool apron is fixed on the tool rest, a spring mechanism is arranged in the tool rest, the tool rest is fixed on the tool disc, the tool disc is fixed on a main shaft of a lathe, and the main shaft of the lathe is fixed on the main shaft of the lathe. The quick tool retracting mechanism comprises a tool holder, a wheel shaft is arranged at the upper end of one side of the tool holder, a connecting rod is arranged on one side of the wheel shaft, the central axis of the connecting rod and the central axis of the wheel shaft do not coincide, an outer wheel is arranged at one end of the connecting rod, and a pipeline is clamped between the outer wheel and a tool bar. And damage to the inner wall and the outer wall of the pipeline can be avoided, the use convenience is greatly improved, and the service life of equipment is prolonged.
