Furthermore, the floating telescopic shaft is in clearance fit with the jack of the handle main body.
Furthermore, the guide hole and the locking hole on the surface of the handle main body are symmetrically arranged, and the axis of the jack of the handle main body is the symmetrical axis of the guide hole and the locking hole.
Further, the feeding adjusting knob is a socket head cap screw.
Furthermore, the hexagonal prism-shaped connecting block is matched with a hexagonal prism hole at one end of the floating telescopic shaft.
After adopting above-mentioned structure, during the use, can insert the hexagonal hole of the telescopic shaft one end that floats with double-end screwdriver pole, the telescopic shaft that floats can let the telescopic shaft that floats stretch out and draw back forward under cylindrical helical compression spring's elasticity effect, guide screw and the epaxial guide way cooperation of telescopic shaft that floats, the guide way has played the guide effect, feed adjust knob and the epaxial locking groove cooperation of telescopic shaft that floats, the locking groove has played fixed locking effect, has restricted the extension length of telescopic shaft that floats.
Advantageous effects
The utility model discloses beneficial effect: simple structure, the structure is reasonable, it is convenient to use, low cost, through the direction of transferring double-model head screw cutter arbor, realize the purpose of installing different model head screws, it installs to have solved the staff and using the screw, the maintenance, the equipment, in the fixed process, need prepare the different screwdriver of multiple model length, cause and carry inconveniently, and during the loading and unloading screw, need to change the screwdriver of different model cutter arbor lengths because of the screw position difference in height, thereby increase staff's intensity of labour and reduce work efficiency's problem.
