By adopting the technical scheme, the working principle and the working process of the invention are as follows: before threading, the electric hand drill is positioned and mounted on the rear side of the rear mounting plate, the power driving end of the electric hand drill is provided with an outer hexagonal column, the outer hexagonal column extends into the inner hexagonal driving sleeve, then two compression bars are respectively inserted into the insertion holes of the left positioning rod and the right positioning rod, the electric hand drill is screwed, the driving screw rod extends forwards, and the front side face of the pressing plate is tightly pressed against the rear end part of the electric hand drill shell. After the electric hand drill is firmly fixed, the steel wire lead is taken out and forwards threaded from the rear end of the hollow worm, passes through the space between the upper wire feeding wheel and the lower wire feeding wheel and then forwards extends out through the hollow shaft. Then use spanner to screw up the press nut, the gland nut will go up the press seat and push down the distance between the seat and reduce, go up the backup pad and use first pivot as the centre and rotate slightly downwards, lower backup pad upwards rotate slightly with the second pivot as the centre, not only can make go up wire feed wheel and lower wire feed wheel can compress tightly the wire lead like this, provide enough frictional force that carries the wire lead forward, can ensure moreover that go up the driving gear and mesh with last driven gear all the time, lower driving gear meshes with driven gear all the time down.

When the front end of the steel wire lead moves to the bending and turning position of the electric wire tube, the bending and turning section is difficult to pass through by simply moving the steel wire lead forwards; at this time, the finger holding the holding tube presses the trigger backward, the trigger drives the two driving rods to rotate upward by taking the supporting shaft as a fulcrum, the pull rod between the rear ends of the two driving shafts drives the braking rods to move downward through the driving sleeve, the spring is compressed, and the upper ends of the braking rods are separated from the positioning groove. Because the front side wall of the installation shell is rotationally connected to the hollow shaft, the rear side wall of the installation shell is rotationally connected to the hollow worm, after the brake disc is released, the hollow worm drives a part of power of the upper worm wheel and the lower worm wheel to drive the installation shell to rotate, the rotation of the installation shell drives the steel wire lead to rotate, and due to the arrangement of the rotary damper, the rotation speed of the installation shell and the brake disc is smaller, so that the hollow worm can continuously transmit a part of power to the upper worm wheel and the lower worm wheel, the steel wire lead is continuously moved forwards, the forward moving speed is reduced, the steel wire lead can be driven to rotate while being moved forwards, and the front end of the steel wire lead can be easily bent and changed to a section of the electric wire tube.

When the curved redirecting section of the electrical conduit is again encountered, the trigger is again depressed. And closing the electric hand drill until the steel wire leads extend out of the outlet of the electric wire pipe.
Of course, when threading operation, just pressing the trigger from the start electric hand drill, liberating the brake disc, the installation shell remains rotatory all the time, and the steel wire lead also moves forward under last wire feeding wheel and the centre gripping of lower wire feeding wheel simultaneously, and the trafficability characteristic of this kind of threading mode is fine, but the threading time is longer.
The hollow shaft not only plays a role in guiding the steel wire lead forwards, but also is used for being rotationally connected with the mounting shell through the fourth bearing; the hollow worm not only plays a role of reducing the rotation speed of the electric hand drill to increase the torque, but also has a role of guiding the wire lead forward and for rotatably connecting the installation housing through the third bearing.

Because the front side wall of the installation shell 7 is rotationally connected to the hollow shaft 5, the rear side wall of the installation shell 7 is rotationally connected to the hollow worm 12, after the brake disc 8 is released, the hollow worm 12 drives a part of power of the upper worm wheel 17 and the lower worm wheel 18 to drive the installation shell 7 to rotate, the rotation of the installation shell 7 drives the steel wire lead 28 to rotate, and due to the arrangement of the rotary damper 6, the rotation speed of the installation shell 7 and the brake disc 8 is smaller, so that the hollow worm 12 can continuously transmit a part of power to the upper worm wheel 17 and the lower worm wheel 18, the steel wire lead 28 is continuously moved forward, the forward moving speed is reduced, the steel wire lead 28 can be driven to rotate while being moved forward, and the front end of the steel wire lead 28 can easily pass through the bending direction-changing section of the electric wire tube. After bending the turning section, the trigger 47 is released, the brake lever 49 is moved upward by the spring 50 and reinserted into the positioning groove 57 to position the brake disk 8, the mounting case 7 is also stopped from rotating, and the wire lead 28 is moved forward only and is not rotated. When the curved redirecting section of the electrical conduit is again encountered, the trigger 47 is again depressed. The electric hand drill 4 is turned off until the wire leads 28 extend out of the outlet of the electric conduit.
Of course, when the trigger 47 is pressed down from the start of the electric hand drill 4 during threading operation, the brake disc 8 is released, the mounting shell 7 always keeps rotating, and the wire guide 28 moves forward under the clamping of the upper wire guide wheel 23 and the lower wire guide wheel 24, so that the threading mode has good passing performance, and the threading time is long.
The hollow shaft 5 in the invention not only plays a role of guiding the wire leads 28 forwards, but also the hollow shaft 5 is used for rotationally connecting the mounting shell 7 through the fourth bearing 33; the hollow worm 12 not only plays a role of reducing the rotation speed of the electric hand drill 4 to increase the torque, but also has a role of guiding the wire lead 28 forward and for rotatably connecting the mounting case 7 through the third bearing 32.
The rotation damper 6 damps the rotation of the brake disc 8 by damping oil.
The left positioning rod 38 and the right positioning rod 39 of the adjustable positioning frame are provided with a plurality of groups of jacks 43 at the rear end parts, so that the adjustable positioning frame can be suitable for electric hand drills 4 with different sizes (lengths) to enable the pressing plate 40, the fixing seat 41 and the screw 42 to move forwards or backwards, and the adjustable positioning frame has wider universality. The electric hand drill 4 is taken down, the device is light and convenient, has small volume and is easy to carry.
The holding tube 46 not only has the function of convenient holding, but also provides a space for installing and hiding the brake lever 49, and the brake lever 49 adopts a structure that the hand-pressing trigger 47 and the spring 50 are reset, so that the structure is simple and compact, labor-saving and easy to manufacture.
