Specific embodiment
The embodiments of the present invention are further illustrated with reference to the accompanying drawing.
A kind of coil pipe Three-jaw sling as illustrated in fig. 1 and 2, including hanging scaffold 1, pull rod 2, sunpender 3 and sliding panel 8, sunpender
Number be 3, the top of the sunpender 3 is hinged on hanging scaffold 1, the pull rod 2 run through hanging scaffold 1, the bottom end of the pull rod 2 with
8 center of sliding panel is fixedly connected；It further include motion bar 4, one end of the motion bar 4 is hinged on the middle part of sunpender 3, the activity
The other end of bar 4 is hinged with end casing 5, is provided with second spring 9 between the motion bar 4 and sunpender 3, and the one of second spring 9
End is arranged on motion bar 4, and the other end of second spring 9 is arranged on sunpender 3, makes motion bar 4 will not be with by second spring 9
Sunpender 3 collides；As shown in figure 3, the inside of the sunpender 3 is provided with sliding slot 31, the edge of the sliding panel 8 be provided with
The convex block 81 that sliding slot 31 matches, the convex block 81 are arranged in sliding slot 31；The bottom end of the sunpender 3 is hinged with chuck 7.Sliding
