Furthermore, the number of the small steel blocks is two, and the small steel blocks are symmetrically distributed;
further, the drill rod slide rails are symmetrically arranged;
furthermore, when the drill rod and the drill rod are connected and sleeved for use, the small steel blocks are clamped into the herringbone clamping grooves;
furthermore, when the drill rod and the drill rod connecting sleeve are used in a matched mode, the position where the small steel block is clamped into the herringbone clamping groove limits the working state of the drill rod.
According to the technical scheme provided by the utility model, the utility model discloses a coil hoist has following technological effect:
1. by using the drill rod device of the utility model, the connecting sleeve is inserted along the slide rail only by inserting the tail part of the drill rod and the drill rod inlet on the connecting sleeve into the herringbone clamping groove, the assembling and disassembling processes of the drill rod are simplified, the time for replacing the drill rod is shortened, the working strength of workers is reduced, meanwhile, the number of people participating in the work is reduced, the labor cost is saved, and the overall working efficiency is improved;
2. the drill rod device of the utility model reduces the use of the connecting sleeve, does not use accessories such as the inserting nail and the spring clip, greatly saves the mechanical use and maintenance cost, and is beneficial to reducing the equipment cost; the possibility that workers are injured by crashing when the drill rod is assembled and disassembled is avoided, and the working safety coefficient of the workers is improved.
In summary, the drill rod device of the utility model simplifies the assembly and disassembly of the drill rod, reduces the working strength of workers, saves the labor cost and improves the overall working efficiency; fittings such as plug pins and spring clips are not used, equipment cost is reduced, the working safety factor of workers is improved, and the method is beneficial to wide popularization and application.

Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings for clarity and understanding of the technical contents. The present invention may be embodied in many different forms of embodiments, and the scope of the invention is not limited to the embodiments described herein.
In the drawings, structurally identical elements are represented by like reference numerals, and structurally or functionally similar elements are represented by like reference numerals throughout the several views. The size and thickness of each component shown in the drawings are arbitrarily illustrated, and the present invention is not limited to the size and thickness of each component. The thickness of the components may be exaggerated where appropriate in the figures to improve clarity.
As shown in fig. 1 and 3, the drill rod device of the present invention comprises a drill rod 1 and a drill rod connecting sleeve 3; the tail part of the drill rod 1 comprises two small steel blocks 2, the cross section schematic diagram is shown in figure 2, and the two small steel blocks 2 are symmetrically arranged; the connecting sleeve 3 comprises a drill rod inlet 5, a drill rod slide rail 4 and a herringbone clamping groove 6, and the drill rod slide rails 4 are symmetrically arranged as shown in the right view in the direction B of fig. 3 as shown in fig. 4; the herringbone clamping groove 6 is positioned in the connecting sleeve 3, is curved near the inlet and is in a straight shape far away from the inlet;
