Three through holes of anchor mechanism；The grappling pincers tooth and be fixed on grappling pincers tooth outer wall that anchor mechanism includes being embedded in each through hole
On adjusting screw rod 201, grappling clamps tooth 2 and realizes that each grappling clamps tooth 2 into casing spider 1 between axle box by adjusting screw rod 2-1
The regulation of distance；A ring-shaped guide rail 4 is installed on the top end face of casing spider 1.
Stability column 5 includes four upper stability columns and four lower stability columns, above four upper stability columns respectively with position
Four lower stability columns in below correspond and between the bottom of upper stability column and the top of lower stability column by being sleeved on
The adjusting set 6 in the two outside is threadedly coupled with adjusting set 6 respectively；Adjusting set 6 has certain length, makes by stable in regulation
Post and lower stability column enable stability column 5 to be carried out according to the cutting position of sleeve pipe to be cut relative to the position of the inner side of adjusting set 6
Elongate or shorten accordingly；Every lower stability column bottom is provided with mutual with the ring-shaped guide rail 4 on the top end face of casing spider 1
The roller of cooperation, it is flexibly connected formation between stability column 5 and casing spider 1, i.e., stability column 5 is against the top end of casing spider 1
And can be circumferentially rotated relative to casing spider 1 on face；
As shown in Figure 1 and Figure 4, lower turn cylinder 7 is press-fitted and is fixed on the top surface of stability column；In the lower side wall of turn cylinder 7
On along the circumferential direction offer three through holes for being fitted with cutter 10, cutter 10 set perpendicular to the lower side wall of turn cylinder 7 and
Blade protrudes from the lower outer wall of turn cylinder 7 towards inner side, knife tail；Wherein, cutter 10 are set and are fixed on logical by two transverse directions
Spring 11 in the hole wall of hole both sides, realization grips and righting cutter 10, and the length of the blade of cutter 10 is more than backspin
Cylinder 7 is moved to the distance of internal surface of sleeve pipe to be cut.
As depicted in figs. 1 and 2, upper turn cylinder 9 is threaded on the lower top outer wall of turn cylinder 7；As shown in Fig. 2 upper
Multiple along the circumferential direction uniform arcs 12 are arranged at intervals with the bottom end face of turn cylinder 9, the both ends of each arc 12 lead to
Trip bolt 13 is crossed to be fixed on the bottom end face of turn cylinder 9；The inwall of each arc 12 to lower turn cylinder 7 outer wall
Spacing gradually increases.Arc 12 is tightened in the same horizontal line and completely with the initial setting up of cutter 10 in upper turn cylinder 9
Original state arc lower plate 12 when on lower turn cylinder 7 is with cutter 10 to be staggered；Specifically, arc 12 and cutter
10 upper surface is located in same horizontal line, and the axial height of arc 12 is more than the diameter of cutter 10 and upper turn cylinder 9
The axial height sum of upper screw thread.
Correspondingly, two rotary handles 8 are provided with the offside side wall of lower turn cylinder 7；In the offside side wall of upper turn cylinder 9
It is provided with two and moves back attacker's handle 901；Specifically, two rotary handles 8 and two move back what attacker's handle 901 was laterally set by two
Cylinder is formed, and size is adapted when the diameter of cylinder is held with people's bracelet, and two cylinders are located in same horizontal line.
The specific method that the realization of the wellhead casing pipe armstrong's patent cutter device is cut to sleeve pipe is as follows：
Make and process and install a kind of wellhead casing pipe armstrong's patent cutter device, casing spider 1 is enclosed on wants downwards
On the sleeve pipe of cutting, three grapplings are adjusted by adjusting screw rod 201 and clamp tooth, 3 grapplings on casing spider 1 is clamped tooth 2 tightly
