The utility model provides a technical scheme that its technical problem adopted as follows:

a drilling tool comprises a tool body, a sleeve and a top head; the cutter body is arranged in the sleeve, the upper end of the sleeve is provided with an opening, and the lower end of the sleeve is provided with a bottom plate; the bottom plate is provided with a through hole for accommodating the cutter body; the cutter body comprises a cutter handle and a cutter head, the cutter handle is positioned in the sleeve, the cutter head is positioned outside the sleeve, a limiting block is arranged on the surface of one end of the cutter handle, and the limiting block is connected with the bottom plate through a spring; the top is fixed at the upper end of the sleeve and abuts against the end part of the knife handle.

Furthermore, the top comprises a positioning block and a top column arranged on the positioning block, an annular groove used for accommodating the sleeve is formed in the end face of the positioning block, and the annular groove is located on the outer side of the top column.

Further, the positioning block is in threaded connection with the sleeve.

Furthermore, be equipped with the shaft hole that is used for the holding tool bit on the fore-set, be equipped with the external screw thread on the surface of fore-set, be equipped with the internal thread of being connected with external screw thread cooperation on the inner wall of through-hole.

Furthermore, a conical head is arranged at the end part of the cutter head, a cutting edge and a reamer are arranged on the surface of the cutter head, and the cutting edge is positioned between the conical head and the reamer.

The utility model has the advantages that:

(1) the utility model fixes the top at the end part of the sleeve opening and supports against the end part of the knife handle, so that the spring is compressed, the knife head is positioned outside the sleeve, and the knife body is extruded and fixed at the moment, thereby the workpiece can be processed; when not using, take off the top, under the effect of spring, the tool bit contracts to the housing in, can preserve like this, and prevents again that the tool bit from revealing and causing the damage outside to improve life.

(2) The utility model discloses a fore-set can compress tightly the handle of a knife in the sleeve, realizes through the ring channel with muffjoint.

(3) The utility model discloses a threaded connection, simple structure, convenient operation.

(4) The utility model discloses can install the top at the telescopic other end, the one end of tool bit promptly, through fore-set and through-hole screw thread fixed connection, the tool bit holding has further protected the tool bit like this in the shaft hole, prevents that dust impurity from getting into the sleeve to avoid damaging the tool bit.

(5) The utility model discloses a conical head is earlier to work piece processing centre bore, has realized the guide effect to cutter drilling, and the rethread cutting edge carries out the processing in hole, carries out reaming and repaiies the hole through the reamer, need not to change the cutter, has saved the time greatly, has improved work efficiency.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of the present invention when not in use;

wherein: the cutting tool comprises a cutting tool body 1, a tool shank 11, a tool bit 12, a conical head 121, a cutting edge 122, a reamer 123, a sleeve 2, a top head 3, a positioning block 31, a top column 32, an annular groove 33, a shaft hole 34, a bottom plate 4, a limiting block 5 and a spring 6.

Detailed Description
