The invention can realize the innovative matching between the guide drill sleeve 1 and the matching drill handle 2, based on the magnetic attraction technology and the phase change characteristics of the phase change filling bag 9, when the phase change filling bag is converted into a liquid mobile phase, the phase change filling bag 9 is forced to deform to actively approach and enter a preset filling hole 7 on the matching drill handle 2, then the compacting effect of filling is improved under the action of the early warning rod 8, and then the phase change filling bag is converted into a solid phase for bridging, so that the high-strength positioning connection is effectively carried out on the guide drill sleeve 1 and the matching drill handle 2, the guide performance of the percussion drill bit 4 during working is indirectly improved, the radial vibration and transverse vibration are greatly weakened, the displacement is sensed in advance by the fragile characteristic of the early warning rod 8 at the initial stage of the displacement, then the percussion bit is broken to release the volatile material in the interior, thereby early warning is timely carried out on technical personnel and being beneficial to, the loss caused by precision deviation is reduced, and a product with higher quality is produced.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
