Embodiment Construction

[0009] As shown in the figure, two symmetrical handles 2 are welded on the disc 2, two symmetrical holes are set on the disc 2 perpendicular to the handle 2, and the holding rod 5 is connected to the oval holding head 3 and passes through the disc In the symmetrical hole on 2, the end of the blocking rod 5 is connected with the baffle 6, and the spring 4 is installed inside the baffle 6.

[0010] When using, pull the baffle 6 outwards with both hands, the blocking head 3 is submerged in the disc 2, and the disc 2 is put on the broken drill bit, and the blocking head 3 is aligned with the groove on the drill bit to loosen the baffle 6. The spring 4 is reset, the blocking head 3 is embedded in the groove of the drill bit, and the blocking rod 5 enters the upper hole of the disc 2 to complete the fixing of the drill bit. The handle 1 can be rotated in the forward and reverse directions to facilitate the removal of the drill bit.

Abstract

The invention provides an emergent detaching device of a drill bit, which can easily take out a broken drill bit. Two symmetric handles are welded on a disk; two symmetric holes are formed in the disk in the direction vertical to the handles; blockage rods are connected with elliptic blockage heads, and penetrate through the symmetric holes in the disk; the tail ends of the blockage rods are connected with baffle plates; and springs are mounted at the inner sides of the baffle plates. The emergent detaching device of the drill bit is simple in structure and scientific in design; and through the elliptic design of the blockage heads, a drilling tool on the drill bit can be prevented from damaging the blockage heads.

Description

Technical field [0001] The invention relates to the field of mechanical drilling, in particular to a drill bit emergency disassembly device. Background technique [0002] In the process of mechanical drilling, it is inevitable to encounter the phenomenon that the drill bit is broken in the drilling hole. Although the drill pipe can provide greater torsion when drilling, it is affected by the direction of the drill pipe connecting thread when the broken bit is taken out. It’s hard to make a difference. Summary of the invention [0003] In order to solve the above problems, the present invention provides an emergency drill bit disassembly device, which can easily take out the broken drill bit. [0004] The present invention is realized as follows: two symmetrical handles are welded on the disc, two symmetrical holes are provided on the disc perpendicular to the handles, and the blocking rod is connected to the elliptical blocking head and passes through the symmetrical holes on the d...
