Left and right sides end wall offers bolt hole, and bolt is provided in the bolt hole, is provided between the bolt and fixed device
Becate chain sling is welded to connect between the drilling rod ontology and square toes by ring block one and ring block two.
Further, the fixed device includes circular block, and the circular block is provided centrally with round hole, the circle
Cross bar is welded between the inner wall of hole, the left and right end of the front side of the fixed device is provided with fixed column.
Further, the docking groove with dock the of same size of block.
Further, the distance between the docking block and the bottom of drilling rod ontology are one centimetre.
Further, the diameter of the circular block is equal to the internal diameter of drilling rod ontology, the close drilling rod ontology of the fixed column
The side radian of inner wall is equal to the radian of drilling rod inner body wall.
Further, the square toes inner wall is provided with the annular reinforcement block to match with bolt hole, and annular reinforcement block with
Square toes inner wall is welded to connect.
Compared with prior art, the utility model has the beneficial effects that the utility model being capable of the side of making by becate chain sling
When head and the fracture of drilling rod ontology weld, drilling rod ontology still is able to take up drill bit by square toes, avoids drill bit and square toes
The problem of stake holes can not salvage is fallen into after fracture, can be reinforced by docking groove and docking block anti-between drill body and square toes
Torsional forces prevents from being broken between drilling rod ontology and square toes, and docking groove and docking block can prevent drill bit and side when broken
Head appearance rotation causes becate iron chains torque to make becate iron chains, and there is a situation where be broken.
