The below described drilling rod being positioned at described position-limiting tube is provided with positioning sleeve, described positioning sleeve comprises positioning sleeve skin and positioning sleeve internal layer, annular light transmission passage is formed between described positioning sleeve internal layer and positioning sleeve skin, the top described positioning sleeve being positioned at described annular light transmission passage is provided with annular light source, described positioning sleeve is provided with the power supply of powering for described annular light source, the outer wall of described positioning sleeve is provided with the gauge tap controlling described on and off switch, is provided with reinforcing prop between described positioning sleeve internal layer and positioning sleeve skin.
Improve as one, the rotation direction of described motor is identical with the rotation direction of screw thread on described position-limiting tube.
As improving further, described motor is provided with control crank, and described control crank is provided with the attaching plug connecting described motor, and described control crank is provided with the shift knob, high speed button and the low speed button that control described motor rotation situation.
Improve as one, the side face of described position-limiting tube is circumferentially evenly provided with some scales, and the outer surface of described cylinder near bottom is provided with some scales be uniformly distributed circumferentially.
Owing to adopting technique scheme, the beneficial effects of the utility model are:
Owing to being provided with support, punch operation is made steadily to avoid rocking, circumference is in transmission connection and connecting rod and drilling rod all slide axially with turning set to be provided with turning set between connecting rod and drilling rod, connecting rod is arranged with Compress Spring, one end and the limited post of Compress Spring offset, the other end and turning set offset, bottom and the position-limiting tube of turning set offset, when carrying out punch operation, the position of prior adjustment position-limiting tube, connecting rod is driven to rotate during motor rotation, and then drive turning set and drilling rod to rotate, to punch, when arriving appropriate depth when punching, the top of drilling rod drops into completely in position-limiting tube and departs from turning set, now drilling rod no longer rotates, therefore, the degree of depth of punching can be controlled by the position adjusting position-limiting tube, and position-limiting tube is provided with groove, scale is provided with in groove, with reference to scale, appropriate location is set to control the degree of depth of punching, use accurate convenience.
Below drilling rod being positioned at position-limiting tube is provided with positioning sleeve, annular light source is provided with in positioning sleeve, light transmission passage is formed between positioning sleeve internal layer and positioning sleeve skin, when annular light source is opened, the light sent is irradiated by circular passage, and shadow surface forms an annular aperture, and the centre of annular aperture is the shade that drilling rod is formed, adjusting pole position makes shadow positions overlap with punch position, can realize punching location.
Because the rotation direction of motor is identical with the rotation direction of screw thread on position-limiting tube, make when punching is to limited depth, avoid due to turning set and position-limiting tube offset and drive position-limiting tube to rotate time, position-limiting tube moves up and drilling rod can not be caused to continue motion and cause punching depth down, controls punching degree of depth safety and accurately.
Because motor is provided with control crank, control crank is provided with shift knob, high speed button and low speed button, easy to operate, realizes punch operation and controls flexibly.
Because the side face of position-limiting tube and cylinder are equipped with scale on the outer surface of bottom, the position of convenient adjustment position-limiting tube is effectively to control the degree of depth of punching.
