Preferably, end casing is also provided with pcb board hold-down screw, and after pcb board hold-down screw runs through end casing, one end extends in clamp groove, and pcb board hold-down screw and clamp groove form threaded engagement.By the degree of depth of adjustment pcb board hold-down screw, the top, one end extended to by pcb board hold-down screw in clamp groove is pressed onto on the edge of pcb board, forms position-limiting action to pcb board.
Preferably, in order to avoid pcb board damage, simultaneously in order to play insulation effect, stent strut is the rigid block rubber of insulation.
In order to avoid pcb board damage, simultaneously in order to play insulation effect, pcb board hold-down screw is plastic screw.
Preferably, the cross section of clamp groove is circular arc.
In order to avoid pcb board damage, simultaneously in order to play insulation effect, stent strut is metal derby, and clamp groove inwall is provided with coatings layer.
The invention has the advantages that: the use amount reducing screw, the spacing clamping effect of PCB is formed with the form of slot, excessive use screw is avoided to cause PCB to damage, efficiency of assembling is high, whole operation can complete within the operating time of tens seconds, and much more than 2 minutes of the operation of traditional structure, the Fast Installation of multi-layer PCB board can be realized.
