A kind of operation principle of groove inner wall drill is: when lock sleeve 2 is unscrewed, clamping seam 59 distance in drill bit clamping 12 becomes large, now drill bit 1 can take out or load onto in clamping hole 60, otherwise, when lock sleeve 2 is unscrewed, clamping in drill bit clamping 12 is stitched 59 distances and is diminished, drill bit 1 is lockable, lower shake-changing arm 3, in cylindrical hole I 28 in the middle part of upper rocker arm 5, reversible lock I 13 is installed, reversible lock II 14, when clockwise turn knobs 9, under the traction of back-moving spring 75, partial gear 71 drives two-way ratchet 68 to rotate clockwise around two-way pawl axis 69, when the steel ball 51 on knob 9 slides to hemisphere groove III 35 position along chute 25, steel ball 51 spring II 74 act under bullet in hemisphere groove III 35, thus fix knob 9, and then pin ratchet 62, when ratchet 62 rotates counterclockwise, the tooth of ratchet 62 can be blocked by the end face of two-way ratchet 68, now two-way pawl axis 69 provides support power, ratchet 68 cannot be rotated counterclockwise, if ratchet 68 rotates clockwise, tooth on ratchet 62 can give two-way ratchet 68 inner cambered surface thrust, because now two-way ratchet 68 is only subject to the elastic force of back-moving spring 75, so the tooth of ratchet 62 easily can turn over along the inner cambered surface of two-way ratchet 68, when running into ratchet 62 inter-lobe clearance, thrust suffered by two-way ratchet 68 disappears, two-way ratchet 68 gets back to latched position again under the effect of back-moving spring 75 elastic force, so just achieve clockwise direction ratchet 62 with upper, lower shake-changing arm turns in the same way, , otherwise, counterclockwise turn knobs 9, counterclockwise ratchet 62 and lower shake-changing arm 3, upper rocker arm 5 turns in the same way, when the steel ball 51 of knob 9 falls in hemisphere groove II 34, 62, ratchet is not with lower lower shake-changing arm 3, upper rocker arm 5 rotates, when carrying out common plane bore operation, the knob 9 of clockwise turn lower shake-changing arm 3 makes its steel ball 51 slide to hemisphere groove III 35 position along chute 25, the knob 9 of turn upper rocker arm 5 makes its steel ball 51 slide to hemisphere groove II 34 position along chute 25, at this moment, as long as operator pins rubber disc 8 on the other hand, another holds handle 11 and rotates clockwise and can carry out common plane bore operation, will when groove inner wall be holed, clockwise turn lower shake-changing arm 3, the knob 9 of upper rocker arm 5 makes its steel ball 51 slide to hemisphere groove III 35 position along chute 25, now, ratchet 62 is clockwise with lower shake-changing arm 3, upper rocker arm 5 rotates, counterclockwise then not with lower shake-changing arm 3, upper rocker arm 5 rotates, when rotating clockwise drill, under sinistral external thread 43 and levogyrate inner thread 67 act on, the ratchet 62 of upper rocker arm 5 moves on screw rod 7, one end that screw rod 7 is connected with rubber disc 8 is away from upper rocker arm 5, now screw rod 7, rubber disc 8 provides support power and power for boring, when handle 11 is threaded to extreme position, oppositely firmly, initial firmly position got back to again by such handle 11, circulate and so forth, just bore operation can be realized, although drill only moves back and forth in an angular range, but due to reversible lock I 13, the effect of reversible lock II 14, drill bit is rotated along a direction all the time, so boring can be realized, after boring terminates, the knob 9 being rotated counterclockwise upper arm 5 again makes its steel ball 51 fall in hemisphere groove I 33 along chute 25, now, ratchet 62 counter clockwise direction and upper rocker arm 5 rotating in same direction, upper rocker arm 5 is then only had to rotate clockwise, when rotating counterclockwise drill, under sinistral external thread 43 and levogyrate inner thread 67 act on, ratchet 62 moves on screw rod 7, one end that screw rod 7 is connected with rubber disc 8 is near upper rocker arm 5, after screw rod 7 screws in ratchet 62 completely, just drill can be taken out from groove.
The utility model has following beneficial effect:
1, multiple functional, wide application;
2, easy disassembling, saves space, is easy to carry;
