To solve above-mentioned technical problem, one aspect of the present invention is：A kind of anti-interference frequency modulation switch is provided, Including a Switch main body, the Switch main body front arranges some data connectors, and the back side of the Switch main body arranges coarse adjustment Switch, the external connection inching switch of the coarse adjustment switch, the Switch main body back side is prolonged its back side extension and is connected with a screen in Net is covered, the shielding sieve bottom is provided with buckle, and the draw-in groove being adapted with buckle, the shielding are provided with the Switch main body Net stretches out and is wrapped in the coarse adjustment switch and inching switch wherein, and in the closing of inching switch most external；It is described micro- Tune switch outermost end arranges the signal input that shielding line is used as the anti-interference frequency modulation switch of the modified.

Preferably, connection member is set between the coarse adjustment switch and Switch main body, and the connection member is used to be socketed slightly Tune switch, it is possible to which, so that coarse adjustment switch is elastic at the Switch main body back side, adjustment receives signal；The data connector with open Close and be also equipped with connection member between body；In front and back between connection member from inside Switch main body together with it is internal to pass through data Line connecting valve and data connector simultaneously connect modem between switch and data connector.

Preferably, lines is provided with the coarse adjustment switch, ridge orientation prolongs coarse adjustment switch longitudinal direction.

Preferably, it is provided with horizontal thread on the inching switch

The situation of prior art is different from, the invention has the beneficial effects as follows：Switch main body two can be fixed on and use device On, adjusted come the frequency for completing to receive signal with rotation by the lateral displacement of Switch main body, can effectively extend device Service life, the impact for avoiding regulation of the electromagnetic interference of outside to switch itself to bring by shielding web frame, while card Button is connected with draw-in groove, removes and installs conveniently, is conducive to the maintenance for switching to change.

Description of the drawings

Fig. 1 is the schematic diagram of the anti-interference frequency modulation switch of embodiment of the present invention modified.

Fig. 2 is embodiment of the present invention gauze screen connection diagram.

Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than the embodiment of whole.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.

Referring to the anti-interference frequency modulation switch of a kind of modified that Fig. 1 is provided, it is characterised in that including a Switch main body 1, institute State Switch main body front and some data connectors 4 are set, the back side of the Switch main body arranges coarse adjustment switch 2, the coarse adjustment switch External connection inching switch 3, the Switch main body back side is prolonged its back side extension and is connected with one week gauze screen 8, the gauze screen Bottom is provided with buckle, and the draw-in groove 81 being adapted with buckle is provided with the Switch main body, and the gauze screen stretches out simultaneously The coarse adjustment switch and inching switch are wrapped in wherein, and in the closing of inching switch most external；The inching switch outermost end The signal input that shielding line is used as the anti-interference frequency modulation switch of the modified is set.

In the present embodiment, connection member 5 is set between the coarse adjustment switch 2 and Switch main body 1, the connection member is used for Socket coarse adjustment switch 2, it is possible to which, so that coarse adjustment switch is elastic at the Switch main body back side, adjustment receives signal；The data Connection member 5 is also equipped between joint 4 and Switch main body 1；Connect from Switch main body inside between connection member in front and back, in it Portion is by data wire connecting valve and data connector and connects modem between switch and data connector.
