On, the position for making 101 face of drill bit need to punch, rotational positioning ring 134 adjusts position of the positioning ring 134 in connecting rod 13,
By the position of the graduated scale 132 of 134 upper surface face of positioning ring, the drilling depth of drill bit 101 is controlled, butterfly is then reversely rotated
Shape bolt 31 overcomes the prestressing force of the first compressed spring so that wing bolt 31 is detached from threaded hole 3, then catches handle 14 to push,
So that motor body 1 moves down；When compression bar 42 is detached from the extruding to normally closed button 4, normally closed button 4 resets closure, motor
Closed circuit is formed between main body 1 and power supply line, motor body 1 opens up work, and drill bit 101 rotates；Continue to push, to aluminium alloy
Plate drills, when the lower end surface of positioning ring 134 acts against 22 upper surface of supporting plate, positioning ring 134 prevent motor body 1 after
It is continuous to move down, reach predetermined drilling depth；Mitigate the downward pressure applied to handle 14, motor body 1 is in the first compression
It springs back under the action of spring, so that motor body 1 rises, is squeezed until compression bar 42 is again formed normally closed button 4, so that motor
The electric current of main body 1 is disconnected, and stops powering to motor body 1, motor body 1 shuts down.
Detailed Jie has been carried out to a kind of portable aluminium alloy building-material factory Special-purpose puncher provided by the invention above
It continues.The explanation of specific embodiment is merely used to help understand method and its core concept of the invention.It should be pointed out that for this skill
