The principle of the present apparatus is that the head and the tail both ends of drill collar are individually placed on the chassis of two groups of locating supports, and drill collar is fallen in
After in middle support plate, middle support plate is depressed, and the fold of left and right limit plate comes up, and surrounds independent space.For various outer diameter
Drill collar, the angle that the fold of left and right limit plate comes up is different (limit plate is blocked by drill collar outer wall), preferably limits drill collar
It shakes, simultaneously as each stop portions are spring connection, spring can play slow use of bestirring oneself.Then pressure rack and chassis
It is connected by Detachable connection structure.At this point, the drill collar end of different tube diameters is supported by drill collar limiting device, above by tension steel
Band is pushed down, and is tightened, and is fastened more stable.
In order to further increase degree of stability, setting positioning plate is that corresponding convex block is arranged in the bottom surface for tensing steel band, and
There is corresponding arc concave shape in non-the two.
Chassis and pressure rack are connected using hasp structure, structure is firm and cost is less.
