The invention relates to the technical field of micro-nano optical fiber, and discloses a micro-nano optical fiber micro experiment structure, manufacturing method of the structure and measuring instrument. The micro experiment structure comprises monomode optical fiber and a capillary glass straight pipe, and ports are formed in the two ends of the capillary glass straight pipe; the middle of the monomode optical fiber is provided with drawing-made micro-nano optical fiber, the monomode optical fiber is arranged in the capillary glass straight pipe in a penetrated mode, and is fixedly connected with the capillary glass straight pipe, and the whole micro-nano optical fiber is arranged in the capillary glass straight pipe and is arranged in a suspended mode. Because the whole micro-nano optical fiber is arranged in the capillary glass straight pipe and is arranged in a suspended mode, under the protection of the capillary glass straight pipe, the micro-nano optical fiber is protected from being polluted, outside dust and vapor are avoided from making contact with the micro-nano optical fiber, optical nature of the micro-nano optical fiber will not be affected, the optical performance of the micro-nano optical fiber will not degrade rapidly along with time, the micro-nano optical fiber is easy to process, long-term and stable practical application of the micro-nano optical fiber can be achieved, and the micro-nano optical fiber is easy to compile with other optical fiber devices.

The invention discloses a method of and an apparatus for fitting or removing a tyre (4) of a vehicle wheel (1), in which at least one fitting or removal tool (5) is guided parallel to the axis (11) ofthe vehicle wheel (1) and the vehicle wheel (1) is moved controlledly perpendicularly to its wheel axis (11) in dependence on a rim contour along which the fitting or removal tool (5) is to be guidedat a small spacing.

The invention relates to an anti-electric-shock socket board. The anti-electric-shock socket board comprises a safety cap (1), three safety cap notches (2), an upper cover button square frame (3), a safety box body (4), three safety box body notches (5), a safety box body lock catch (6), a power switch button (7), a safety cap fastener tape (8) and a socket electric wire hole (9). According to the anti-electric-shock socket board, a cap with a socket and a method for locking the cap with the socket are adopted so that a number of normally-used plugs are fixed and then the cap is covered and locked to ensure that a child cannot contact the pugs, as a result, the safety of a multi-purpose socket is ensured fundamentally, and the power utilization safety for children is ensured from the other side.

The invention relates to a method for assembling a fuel cell stack. The method comprises a step (1) of providing a fixing mechanism, a location mechanism, a pressure supply mechanism and a locking mechanism; a step (2) of successively placing a lower end plate, a current collecting plate, an assembly stack single cell, a current collecting plate and an upper end plate of the stack into the fixing mechanism in sequence, wherein each location post of the fixing mechanism is perpendicular to the stack to enable the periphery of the stack to be nested in a space defined by a second surface of each location post; a step (3) of utilizingpressure blocks of the pressure supply device to exert pressure in the direction perpendicular to the stack on the upper end plate and the lower end plate of stack parts to compress each part of the stack to meet set requirements; a step (4) of utilizing the locking mechanism to fix each part of the stack to achieve the purpose of assembling the stack; and a step (5) of removing the pressure, removing the fixing mechanism and the location mechanism and taking down the stack to finish the assembly of the stack. The method for locating and assembling the assembly stack is simple and convenient to operate, high in actionability and precise in location. The location mechanism ensures that all parts of the stack are in contact uniformly without deviation. The pressure blocks of the pressure supply device ensure each assembly of the assembly stack to be forced uniformly, and the quality of the assembly stack is guaranteed.

The invention discloses a multifunctional set-top box fixing device, and relates to the technical field of electronic products. The multifunctional set-top box fixing device comprises a base box, thebottom of the inner wall of the base box is fixedly connected with a motor, and an output shaft of the motor is fixedly connected with a heat dissipation fan; a ventilation opening is formed in the positioning, opposite to the heat dissipation fan, of the top of the base box in a penetrating mode, and the inner wall of the ventilation opening is fixedly connected with a dustproof net; fixed cylinders are fixedly connected to both sides of the top of the base box, and the inner wall of each fixed cylinder is slidably connected with a sliding rod; a first fixed block is fixedly connected to theend, close to the heat dissipation fan, of each sliding rod, and a second fixed block is fixedly connected to the end, away from the heat dissipation fan, of each sliding rod. The multifunctional set-top box fixing device has two functions of plane fixing and hanging, can be flexibly used in different environments, can fix set-top boxes with different sizes, and has the function of heat dissipation, and performance of the set-top boxes is more stable in the using process.
