Detailed Description
Please refer to fig. 1-4, for the utility model provides a steel bar hole digger, including hole digger body 1 and the connecting handle 2 of setting at hole digger body 1 tip, hole digger body 1 is equipped with chip groove 3 along its periphery, is equipped with more than one installation notch 4 on the tip of hole digger body 1, corresponds on the installation notch 4 and sets up cutting block 5, and cutting block 5 top surface is equipped with four cutting faces 6, and four cutting faces 6 form five cutting edges 7 with two sides of cutting block 5.
For solving the technical problem that exists among the background art, the utility model discloses an adopt the mode that sets up a plurality of cutting blocks 5, to concrete drilling's in-process, can share impact load, set up five cutting edges 7 simultaneously on cutting block 5 to this increases cutting block 5's cutting force, can cut the reinforcing bar.
An auxiliary chip groove 8 is formed in the position of the mounting notch 4 along the axial direction of the mounting notch, and the auxiliary chip groove 8 is communicated with the chip groove 3. The auxiliary chip discharge groove 8 is arranged to facilitate the discharge of cutting chips, for example, chips generated by cutting the reinforcing steel bars by the cutting block 5 are guided to the chip discharge groove 3 through the auxiliary chip discharge groove 8 and discharged.
As shown in fig. 4, the hole cutter body 1 has a hollow section 9, and more than one through hole 10 is opened on the outer peripheral surface of the hollow section 9. The provision of a hollow section 9 enables the tapper body 1 to maintain a certain rigidity and enables the cut chips to be led out through the through hole 10.
The end part of the connecting handle 2 is provided with more than one positioning part 11 which is sunken inwards. The positioning part 11 is used for connecting external equipment.
The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
