Four grooves are symmetrically arranged with the rectangular block coordinated with the rectangular channel on macropore hole wall, the hole wall of aperture, spill clamp passes through
Rotating shaft is arranged in groove, and spill clamp top and bottom are provided between claw, the claw of spill clamp and are provided with slip ring,
Spring b is provided between spill clamp one end of slip ring and the side wall of spiral stabilizer body, it is another with spill clamp
Screwed hole is provided with the side wall for holding corresponding spiral stabilizer body, screw is arranged in screwed hole, is set in the outer rim of slip ring
Projection is equipped with, projection is arranged in the chute on aperture hole wall, is set between the top and bottom in projection upper and lower ends and chute
It is equipped with spring a, aperture and is provided with joint, joint outer rim is provided with annular groove, annular groove is correspondingly arranged with spill clamp, joint and company
Connect block connection.
Specifically, contiguous block, joint and sleeve pipe outer rim are interference fitted.
The utility model is designed, simple in construction, easy to operate, and usability is strong, and firm and durable adds and contiguous block is helped
Positive force, while having benefit easy for installation.By being arranged on the first stable block, the second stable block and the 3rd stable block not
Set raised with position, may be such that mud or fluid rotate in the horizontal direction, it is to avoid the first stable block, the second stable block occur
Projection is set to cause to suppress stifled situation with the same position of the 3rd stable block.

Embodiment
As shown in Fig. 2 in a kind of spiral stabilizer, socket and the outer wall of sleeve pipe 19, including stabilizer body 14, stabilizer sheet
It is evenly equipped with the stable block 3 of the stable block the 2, the 3rd of the stable block 1, second of first set in the shape of a spiral on the periphery of body 14, described the
It is provided with projection on the stable block 3 of the stable block 2 and the 3rd of one stable block 1, second, the raised position of the first stable block 1 is on top, the
The raised position of two stable blocks 2 is at middle part, and the raised position of the 3rd stable block 3 is in bottom.In the mistake of the delivery cannula 19 into well
Cheng Zhong, when the borehole wall has projection or when the dive of sleeve pipe 19 is obstructed, revoling tube 19 makes it drive spiral stabilizer rotation, helically
The first stable block 3 of the stable stable block the 2, the 3rd of block 1, second that shape is set is easier to decline when rotated.
The upper and lower ends of stabilizer body 14 are each provided with macropore 15, and aperture 16 of two macropores 15 in the middle of it is connected, greatly
It is uniformly arranged on the hole wall in hole 15 in the rectangular channel 11 perpendicular to horizontal plane, macropore 15 and is provided with contiguous block 4, contiguous block 4
Outer rim is provided with the rectangular block 18 coordinated with the rectangular channel 11 on the hole wall of macropore 15, the hole wall of aperture 16 and is symmetrically arranged with four
Groove 8, spill clamp 7 is arranged in groove 8 by rotating shaft, and the top and bottom of spill clamp 7 are provided with claw, spill clamp
Slip ring 9 is provided between 7 claw, is set between one end of spill clamp 7 of slip ring 9 and the side wall of spiral stabilizer body 14
Spring b17 is equipped with, screwed hole, spiral shell are provided with the side wall of spiral stabilizer body 14 corresponding with the other end of spill clamp 7
Nail 20 is arranged in screwed hole, projection 13 is provided with the outer rim of slip ring 9, projection 13 is arranged on the chute 12 on the hole wall of aperture 16
It is interior, it is provided between the upper and lower ends of projection 13 and top and bottom in chute 12 in spring a10, aperture 16 and is provided with joint 5,
