Specific embodiment
The embodiments of the present invention are described further referring to figs. 1 to Fig. 5.
The present embodiment specific structure：Including pedestal 1 and the rack being placed on pedestal 12, rack 2 is equipped with motor 21 and bores
Machine 3, drilling machine 3 include drive plate 31, transmission shaft and drill bit 4, and the output end of motor 21 is connected by belt 21a and drive plate 31,
Drill bit 4 is placed on the output end of rotation axis, and drill bit 4 includes fixture and drilling rod 5, and drilling rod 5 and fixture are detachably connected, the pedestal
1 is equipped with guide rod 12, the connection that rack 2 and guide rod 12 are slided, and rack 2 is equipped with the handle 22 of driving transmission shaft lifting.
Constituting in fixture has the hollow cavity protruded into for drilling rod 5, and fixture includes top base 42 and bottom base 41, top base
42 and bottom base 41 be rotatablely connected, bottom base 41 includes outer barrel 411 and inner cylinder 412, outer barrel 411 and inner cylinder 412 it
Between constitute and have for the movable active chamber of top base 42, the bottom of top base 42 is equipped with reverse plate 6, and reverse plate 6 is placed in lower base
It is rotatablely connected in the end of seat 41 and with bottom base 41, constituting on the end of bottom base 41 has circular groove 40, on the inner wall of circular groove
Several tooth sockets 401 are furnished with, are set on reverse plate 6 there are two elastic slice 61, elastic slice 61 and tooth socket contradict.On inner cylinder 412 constitute due to
The limit chamber that drilling rod 5 protrudes into, open up on inner cylinder 412 there are two and limit chamber notch 410, top base 42 protrudes into
Notch is corresponded in the main body inner wall of active chamber is equipped with the ring eccentric wheel 4a that can be protruded into notch and contradict with drilling rod 5.
