The invention discloses a fire-linked balcony railing escape passage, which includes a pair of openable railings and a railing opening mechanism respectively arranged on the left and right sides of the balcony. Both sides of the balcony are provided with railing installation grooves. The channel side fence and the lower side of the receiving side fence are hinged in the corresponding fence installation groove, and the upper part of the openable fence is locked and fixed by a mortise lock structure, and the fence opening mechanism is connected with the fire Detectors or fire alarm switches are connected to control the unlocking of the mortise lock structure, and the opening mechanism of the fence is arranged on one side of the side fence of each channel, and the side fence of the channel is provided with a channel receiving mechanism and a tubular channel, so The bottom of the tubular passage falls onto the receiving side fence in the open state when the passage side fence is in the open state. The present invention does not affect the use space of the balcony, and at the same time, the openable railing provided can form an escape passage automatically when the balcony is closed, and does not affect the escape.

The invention provides a numerical control machine tool. The numerical control machine tool comprises a workpiece clamping mechanism and a cutter clamping mechanism, wherein the cutter clamping mechanism comprises a positioning shaft, the positioning shaft is sleeved with a cutter disc, at least two cutter movement grooves are formed in the cutter disc, and cutters are arranged in the cutter movement grooves in a penetrating mode in the axial direction of the cutter disc; the positioning shaft is located at the center of the cutter disc, a cuter pushing mechanism used for pushing the cutters to the positioning shaft from the direction away from the positioning shaft is arranged in the cutter movement grooves, the cutter pushing mechanism is provided with a cutter locking / automatic unlocking mechanism, a cutter restoration mechanism used for pulling the cutters to be close to the outer edge of the cutter disc along the cutter movement grooves is arranged in the cutter movement grooves, and the cutter pushing mechanism is provided with a sliding guide rail mechanism and a pushing and sliding driving mechanism; a cutter capturing mechanism is arranged on the positioning shaft. The numerical control machine tool has the advantages that multiple groups of cutters are arranged in the cutter disc in a hidden mode, using is safe, actuating units used for cutter change are reasonably arranged, and cutter change is stable and smooth.

The invention provides a control system of an intelligent charging pile and a charging method of a storage battery. The control system of the intelligent charging pile comprises an operation terminal, a processing terminal and the charging pile, wherein the operation terminal receives a charging instruction transmitted by a user, and transmits the charging instruction to the processing terminal; the processing terminal analyzes the charging instruction to determine the charging pile used for charging a to-be-charged battery; the charging pile detects voltage of the to-be-charged battery, receives a charging mode transmitted by the processing terminal, and determines a charging scheme for the to-be-charged battery according to the voltage and the charging mode. In the control system of the intelligent charging pile, the charging pile can analyze the voltage and the charging mode of the to-be-charged battery to determine the charging scheme for the to-be-charged battery, so that the determined charging scheme is more scientific; a charging process is safer; the technical problems of low safety and poorer intelligent degree of the conventional charging pile during charging of the to-be-charged battery are alleviated.
