Retain problem in the pipeline for solving the cutting chip, the utility model is set with magnetic material ring and spring successively at the rear portion of described centre drill, the effect of this spring is to shore the magnetic material ring, make it all the time near boring cutting position, the strong magnetic force that utilizes magnetic material self to be had will cut chip and cut by ring-like drill bit under circular slab be adsorbed in the lump on the magnetic material ring and take out of.
Positive stop key described in the utility model is made up of two recessed keys of symmetrically arranged semicircle camber, two pull bars pass two gathering sills that symmetrical worker goes out on the drilling tool body respectively and combine with two recessed keys of semicircle camber, and the effect that is installed on the spring on the pull bar is to make two recessed keys of symmetrically arranged semicircle camber be in closure state all the time.
Operation principle of the present utility model is as follows:
When using hand pipeline drilling machine of the present utility model on duct wall, to hole, ring flange that can be by being positioned at drilling tool body front end is with on the arm that drilling machine is connected with trunk line combines, make positive stop key break away from drilling rod by the mode of mentioning pull bar then, and push ahead drilling rod fast, during when drill bit arrival or near the cutting position place, positive stop key can be installed in the limited ring groove of the corresponding position that processes on the drilling rod by auto-closing under the effect of spring, make drilling rod pass through positive stop key, the supporting ring flat-plate, crimping ring flat-plate and hand-operated feed ring constitute a monoblock type axial displacement linkage structure, can drive the hand-operated feed ring this moment by the mode that cooperatively interacts and hole with the ratchet-type turning handle that is positioned at the drilling rod rear end.After boring finishes, make positive stop key break away from drilling rod by the mode of mentioning pull bar once more,, and close valve on the arm rapidly, promptly finish boring work fast to the drilling rod of pulling back.
That the utility model not only has is simple in structure, use flexibility and reliability, in light weight, the advantage easily of carrying, install, cut to, and can adapt to multiple construction site needs, effectively solve problem in the residual pipeline of iron filings in the boring procedure, save the non-cutting time of construction greatly, increase work efficiency.
