The invention discloses an improved porous wire type binding machine. The improved porous wire type binding machine comprises a machine frame, a control circuit, a binding platform, a drilling mechanism and a wire feeding mechanism, wherein the binding platform is arranged in the middle of the machine frame; the drilling mechanism is arranged above the binding platform, and the drilling mechanismis provided with three drilling cutters; the wire feeding mechanism is positioned below the binding platform, the wire feeding mechanism is provided with three machine needles, each machine needle isaligned with the corresponding drilling cutter in parallel, a receding groove opening is formed in the binding platform, the binding platform is used for receding the drilling cutters and the machineneedles, the receding groove opening penetrates through the binding platform up and down, the receding groove opening transversely penetrates each drilling cutter and each machine needle, and the width of the receding groove opening is larger than the outer diameter of the drilling cutters and the outer diameter of the machine needles. Compared with the prior art, the binding machine can be used for receding the use of a conductive rubber pad and a rubber pad translation mechanism, receding the drill cutters in the downward drilling process, so that a binding line can be conveyed to penetratethrough the binding platform and a binding hole, and the whole machine is low in cost and good in stability.
