The movable sliding block 6 is of a hollow tubular structure with an opening at the top, and the aperture of the opening at the top of the movable sliding block 6 is smaller than the outer diameter of the large-diameter end of the pull rod. The outer diameter of the movable sliding block 6 is matched with the inner diameter of the sleeve 3, and the movable sliding block 6 is inserted into the sleeve 3 from the bottom of the sleeve 3 and stressed to move up and down in the sleeve 3. The bottom of the movable sliding block 6 is provided with a lead hole pin 7 in a threaded connection mode.

Furthermore, the diameter of the hole guiding pin 7 is determined according to the aperture of the hole to be guided, and the hole guiding pin can be detached and replaced.

The utility model has the advantages that:

1) The device adopts the structure of handle, L type work piece, sleeve pipe, slider and draw the hole round pin, has realized the lead hole and has fixed a position fast, guarantees to draw requirements such as hole axiality, convenient operation, raises the efficiency. 2) Due to the adoption of the structure of the handle, the L-shaped workpiece, the sleeve, the slider and the hole leading pin, the defects of narrow hole making space and low hole coaxiality are overcome, the problem that hole leading in narrow space and hole leading in a thick part are difficult is effectively solved, and the device is simple, convenient to develop and practical and has high economic benefit.
