It is understood that in other embodiments, the fixture 100 may be used in other environments where equipment is secured to wires.

The fixture 100 is used for the fixation of the coil wire 200 in the valve. The fixing device 100 has a slit 10 between the coil guide 300 and the coil lead 200, and the fixing device 100 presses the coil lead 200 against the coil guide 300 through the slit 10, thereby fixing the coil lead 200.

In the existing coil, the coil wire is directly led out from the coil, and the coil wire is frequently repeatedly pulled in the process of installing the valve or connecting the wire to the valve, so that the stress of the leading-out end of the coil wire is concentrated, the service life of the coil wire is reduced, and even the leading-out end of the coil wire is pulled apart and short-circuited. This creates a potential risk for fluid control of the valve.

With this configuration, the coil conducting wire 200 is inserted into the gap 10 between the fixing device 100 and the coil guide 300, and the fixing device 100 presses the coil conducting wire 200 onto the coil guide 300 through the gap 10, thereby increasing the stress point of the coil conducting wire 200, i.e. the contact point 220 on the coil conducting wire 200 pressed by the fixing device 100. When an operator pulls the coil wire 200, the contact point 220 of the coil wire 200 and the fixing device 100 can be pressed, so that the pulling force is more concentrated on the contact point 220, thereby reducing the pulling force applied to the leading end 210 of the coil wire 200, further preventing the coil wire 200 from being torn or short-circuited at the leading end 210, and ensuring that the fluid control of the valve can be normally realized.
