A fixing device for a triode

The utility model discloses a fixing device for a triode. The fixing device for the triode comprises a base plate (10), a fixing clamping plate (20), a movable clamping plate (30), a telescopic spring (40) and a fixing block (50). A fixing hole (101) is arranged in the base plate. The fixing clamping plate is vertically fixed on the base plate. The base plate is provided with a slide chute (102). The movable clamping plate is provided with a slide block which is clamped in the slide chute (102). The fixing block is vertically fixed on the base plate. One end of the telescopic spring is fixed on the fixing block, and the other end is fixed on the movable clamping plate. The fixing clamping plate is parallel to the movable clamping plate. The fixing clamping plate and the movable clamping plate are perpendicular to the slide chute. The base plate is fixed on electronic equipment or an electronic device through the fixing hole. The triode is clamped between the fixing clamping plate and the movable clamping plate. Through the above technical scheme, the triode can be both directly taken away from the base plate and installed on the base plate again. Installing and dismounting of the driode together with the base plate is not needed, so that the replacement of the triode is convenient, and material consumption in practical application is saved.
