The cover plate is provided with a pressure plate 30 that can be adjusted up and down in the seating seat, and a pair of rescue cutter heads 40 with adjustable spacing are arranged on the underside of the pressure plate, so that the rescue cutter head can be driven downward by the pressure plate, and the rescue cutter head can be passed through the rescue. The cutter head is disassembled into the gap between the main pipe of the repair pipe and the inserting plate to realize the demolition action.

In this embodiment, in order to realize the locking of the cover plate and the seat, the locking mechanism includes a locking screw 11, the lower end of which is hinged with the outer extension 12 of the other upper end of the seat, and the cover The other end of the plate is provided with a groove 21 for inserting the locking screw, and the locking screw is also screwed with a thumb nut 13 . Therefore, after the locking screw rod is buckled into the groove, the locking of the cover plate and the seat is completed by tightening the hand nut.

In this embodiment, in order to realize the lifting of the pressure plate, a vertical screw 31 is screwed on the cover plate, and the lower end of the vertical screw is rotatably connected with the upper end surface of the pressure plate through a rotating mechanism such as a bearing. The vertical guide rods 32 are respectively fixed on each part, and the vertical guide rods pass through the cover plate and are slidably connected with the cover plate. Thereby, the rotating action of the vertical screw is converted into the lifting action of the pressing plate, and the lifting guide is realized through the vertical guide rod.

In this embodiment, in order to drive the vertical screw to rotate, a driving handle 33 is fixed to the upper end of the vertical screw.

In this embodiment, in order to realize the distance adjustment between a pair of cutter heads, both sides of the lower part of the pressure plate are provided with slide grooves 34, and a breakaway cutter head 40 slidingly matched therewith is arranged in the slide grooves. The pressing plate is provided with a transverse threaded rod 35 passing through the two chutes and both sides are rotatably connected with the pressing plate. Phase screw connection. Thereby the distance adjustment between a pair of rescue cutter heads is realized by the rotation of the transverse screw rod.

In this embodiment, in order to drive the horizontal screw to rotate, a drive end 36 is fixed at one end of the horizontal screw passing through the pressing plate. The middle part of the screw rod is rotatably connected with the pressure plate, so as to ensure the connection strength between the horizontal screw rod and the pressure plate.
