When the hole is drilled,
the front end of the section bar is placed at a drilling station (an opening 31 at the lower end of the middle part of a supporting plate), the drilling position is located under a drill bit 9 of an electric drill body, after a worker pedals a button of a power switch S1 at the toe, an internal contact of the power switch S1 is closed, so that a relay K2 can be electrically attracted to a control power input end of the relay and a normally open contact end of the relay, and then the pressure sensor A2 and a detection circuit, and a time control switch A3 is electrically operated (one-way conduction of a diode VD). After the pressure sensor A2 and the detection circuit are powered on (the electric drill body M2 is powered on after the relay K3 is powered on and is attracted), two poles of a 12V power supply enter positive and negative poles of power supply input ends of two sets of electric push rods AM1 through two control power supply input ends and two normally closed contact ends of the relay K1, and then movable columns of the two sets of electric push rods AM1 push the clamping blocks 4 to move towards the inner side ends to gradually clamp the profile.

As shown in fig. 1 and 2, after the time control switch A3 is powered on, the 3 and 4 pins of the time control switch A3 output positive and negative power supplies for a certain time at intervals (for example, output 10 seconds power supply for 4 seconds, the time period is 4 seconds as the required time for clamping the profile, and 10 seconds as the time for drilling, and the specific time is adjustable)) enter the positive and negative power supply input ends of the electric push rod M3, so that the movable column of the electric push rod M3 gradually pushes the drill bit 9 of the electric drill body to automatically drill the profile from top to bottom. After the operator finishes the visual drilling, when the operator does not step on the button of the power switch S1 any more, the relay K2 loses electricity and does not attract the control power input end and the normally closed contact end to be closed, and then the negative and positive electrode power input ends of the two sets of electric push rods AM1 timely control the switch A4 to work (the diode VD1 is conducted in one direction). After the negative and positive electrode power supply input ends of the two sets of electric push rods AM1 are powered on, the movable columns of the two sets of electric push rods AM1 drive the clamping blocks 4 to move towards the outer side end gradually and pull the distance from two sides of the section bar, and the right side end of the clamping block right side end of the movable column of the right end set of electric push rods AM1 is in contact with an open circuit of an internal contact of a button of the electric power switch AM1 before the movable columns of the right end set of electric push rods AM1 move to the outer dead center, so that the two sets of electric push rods AM1 are powered off, and the electric push rods AM1 are prevented from being damaged due to uncontrolled work. After the time control switch A4 is powered on, the 3 and 4 pins of the time control switch A4 output power sources for a certain time (for example, 10 seconds, the specific time is adjustable) to enter the negative and positive electrode power source input ends of the electric push rod M3, so that the movable column of the electric push rod M3 gradually moves up and down the drill bit 9 of the drill body to be ready for the next drilling. In exactly the same way as described above, the worker can drill another profile or send the profile backwards along the opening 31, and drill the next position of the profile.
