Abstract: The invention provides a power supply including at least one power output port, at least one status alert component, and at least one output port status monitoring module. The status alert component generates at least one visual prompt based on an alert signal. The output port status monitoring module includes at least one temperature sensor adjacent to the power output port, a microcontroller connected to the temperature sensor and sensing an output current from the power output port, and a reset signal generator connected to the microcontroller. The microcontroller comprises at least one port status alert condition that takes a temperature and the output current of the power output port as decision factors. The microcontroller outputs the alert signal to the status alert component when the port status alert condition is met and maintains the status until a reset signal provided by the reset signal generator is received.

Abstract: An adjustable axial gap of the thread rod assembly has a brace, a thread rod rotationally deployed onto the brace, a thread bearing for gripping one end of the thread rod is screwed into the first positioning hole of the brace, and one side of the thread bearing withstands against the thrust washer. The user may rotate the thread rod by applying force passing through the thrust washer onto the thread rod and shifting an axial moving of the thread rod to adjust the axial gap of the thread rod assembly which attains the merits of simple installation and easy application.

Abstract: A slide block assembly mounted on a thread rod having a slide block and an entraining element. The slide block is coupled up by two slide units with an inner bore of spiral surface for screwing connection. The entraining element is deployed outside of the slide block for restraining the slide units in help of solving the problem as block seizing by slightly enhancing torque onto the block, so as to create a block gap leading an automatic consequence of slide block's restoration from deviation resulted from an inappropriate screw between the thread rod and the thread bore.
