According to the technical scheme, the leather cutting head for the protection shoes is characterized by comprising an installation shell, a suction assembly, a cutting assembly and a safety assembly, the cutting assembly is rotationally connected to the installation shell, the safety assembly is slidably connected to the installation shell, and the suction assembly is installed on the side face of the installation shell and connected with the cutting assembly; use safety is guaranteed through the physical structure of the safety assembly, if an accident occurs in the cutting process, the safety assembly can be immediately used for stopping the cutting assembly, the cutting assembly allows the cutting head to automatically adjust the cutting-in angle according to a path through the rotating connection design, blade abrasion is reduced, edge smoothness is improved, and the cutting efficiency is improved. And the purpose that meat tendons and other places are cut without being clamped is achieved.

The present application relates to infusion pump technology field, especially infusion device control method, before the user starts to use the device, the self-locking type switch circuit is disconnected, the system is in zero power consumption complete power-off state, when the user starts to use the device, the trigger signal of opening the device is generated, the switch circuit is turned on and self-locked, and the control circuit is powered; thereafter, the system controls the subsequent process by accumulating the number of pulses sent to the drive mechanism: when the pulse number reaches the first preset value, the initialization is completed; when the second preset value is reached, the trigger of the needle assisting mechanism is completed, and the infusion needle is implanted into the human body; finally, according to the user setting infusion instruction starts infusion. The control method ensures the safety of the infusion device through the hardware barrier, realizes the automatic and accurate control of the initialization and needle assisting mechanism by using single pulse counting, and realizes the true zero standby power consumption, which significantly improves the safety, reliability and user experience of the infusion device.

The application relates to an inflator pump device, comprising: an air guide pipe; and an inflator pump body provided with a limiting part and a switch, the limiting part being configured to be capable of limiting the air guide pipe, and the switch being electrically connected to the inflator pump body; wherein when the air guide pipe is in limiting cooperation with the limiting part, the air guide pipe triggers the switch, and the inflator pump body is in a shutdown state; when the air guide pipe is separated from the limiting part, the air guide pipe is separated from the switch, and the inflator pump body is in a working state. The inflator pump device provided by the application can realize automatic start and stop of the inflator pump device through taking and placing actions of the air guide pipe, and solves the problems of complicated operation and low efficiency of a traditional inflator pump.
