Zusammenfassung:The invention belongs to the technical field of unconventional oil-gas well pressure perforation, and particularly relates to a device for handling cable clamping caused by sand in a choke tube duringpressure perforation. The device is compact in structure and high in operability and can rapidly handle the problem of cable clamping caused by the sand in the choke tube during the pressure perforation, and therefore help is provided for improving the handling efficiency of such engineering accidents. The device for handling cable clamping caused by the sand in the choke tube during the pressureperforation includes a choke-tube clamp hoop, a choke-tube outer sleeve clamp hoop, a nut for the choke-tube clamp hoop, a nut for the choke-tube outer sleeve clamp hoop and a lead screw; the choke-tube clamp hoop is composed of two choke-tube fast fixing parts which are in the same shape; each choke-tube fast fixing part is provided with two choke-tube clamp hoop fastening holes and a choke-tubeclamp hoop lead-screw conn
