Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The invention is described in detail below with reference to fig. 1 and 2:

embodiment 1, as shown in fig. 1 and 2, an internal flat thread connection drilling rod, including motor 3, threaded drill rod 4, puddler 5 and split card hand 6, the top of stirring stake support 1 sets up hydraulic equipment 2, and hydraulic equipment 2's output is connected on motor 3, and motor 3's output and threaded drill rod 4 upper end threaded connection, threaded drill rod 4 lower extreme and puddler 5 upper end threaded connection, the upper and lower end screw thread of threaded drill rod 4 is the same, and when the motor rotated, motor 3 was locked or the deblocking simultaneously with threaded drill rod 4 and puddler 5. Clamping grooves 5.1 are symmetrically arranged in the middle of the stirring rod 5, and the clamping grooves 5.1 can be two symmetrically arranged inwards concave planes or outwards convex plane structures; the splitting clamping arm 6 comprises a first clamping arm 6.1, a second clamping arm 6.2 and a stop lever 6.3; stop lever 6.3 sets up the terminal surface at split card hand 6 for in dismantling or the installation, block puddler 5 and restrict its motion, thereby accomplish quick dismantlement or installation, first joint arm 6.1, second joint arm 6.2 can pass the spacing puddler 5 of joint recess 5.1 and rotate. Therefore, the technical problem that the existing connecting drill rod is welded or fixedly connected with a flange screw and inconvenient to mount and dismount is solved. The installation is dismantled sooner, and is laborsaving convenient more.

Embodiment 2, as shown in fig. 1, fig. 2, an internal flat thread buckling connection drilling rod, including motor 3, screw rod 4, puddler 5 and split card hand 6, the top of stirring stake support 1 sets up hydraulic equipment 2, and hydraulic equipment 2's output is connected on motor 3, and motor 3's output and screw rod 4 upper end threaded connection, 4 lower extremes of screw rod and 5 upper end threaded connection of puddler, the upper and lower end screw thread of screw rod 4 is the same, and when the motor rotated, motor 3 was locked or the deblocking simultaneously with screw rod 4 and puddler 5. Clamping grooves 5.1 are symmetrically arranged in the middle of the stirring rod 5, and the clamping grooves 5.1 can be two symmetrically arranged inwards concave planes or outwards convex plane structures; the splitting clamping arm 6 comprises a first clamping arm 6.1, a second clamping arm 6.2 and a stop lever 6.3; stop lever 6.3 sets up the terminal surface at split card hand 6 for in dismantling or the installation, block puddler 5 and restrict its motion, thereby accomplish quick dismantlement or installation, first joint arm 6.1, second joint arm 6.2 can pass the spacing puddler 5 of joint recess 5.1 and rotate.
