A fixing groove 15 is formed in the protruded portion of the connection groove 14 and when a pair of adjacent guide members 10 are assembled by the fixing groove 15 and are positioned in parallel with each other, The fixing protrusion 22B of the connector 20 to be described later is inserted into the fixing groove 15 and its position is fixed.

The guide body 10 of the crown guide 2 is formed into a cylindrical shape having various diameters corresponding to the crown size and the tooth condition to be used and the guide body 10 having different sizes To be used in a line.

The connecting hole 20 is inserted into and fixed to the coupling hole 12 in the direction in which the coupling protrusion 13 is not formed and is assembled with another guide body 10 positioned adjacent to the coupling hole 20 using the coupling hole 20.

7 and 8, the coupling 20 is inserted into and fixed to the opposite side of the coupling hole 12 of the guide main body 10 on which the coupling step 13 is not formed, A locking part 22 integrally formed on one side of the fixing part 21 and having a relatively larger diameter than the fixing part 21 and a locking part 22 formed on one side of the locking part 22, And a fitting insertion portion 23 that is inserted and fixed to the coupling hole 12 of another guide main body 10 formed integrally with the coupling protrusion 13.

8, a plurality of insertion insert portions 23 are formed in a radial shape at predetermined intervals from each other as shown in FIG. 8, and a plurality of insertion insert portions 23, (More preferably two or more) engaging protrusions 23B are protruded partially along the outer surface of the fitting insertion portion 23. [

The outer side surface of the other fitting insertion portion 23 in which the locking protrusion 23B is not formed is formed in a plane 23A which is formed in a plane with a constant width so as to correspond to the plane formed in the locking protrusion 13 of the guide main body 10, .

The engaging portion 22 is engaged with the engaging portion 22 on the outer surface of the guide body 10 when the engaging hole 12 of the engaging hole 20 is inserted into the engaging hole 12 of the guide body 10 The crown guide 2 is inserted into the coupling hole 12 of the guide main body 10 when the pair of crown guides 2 at the adjacent positions are assembled, 20) to prevent them from moving easily.

To this end, the engaging portion 22 on the side opposite to where the guide body 10 is positioned is formed in a shape corresponding to the connection groove 14 of the guide body 10 as shown in Figs. 8 and 9 (a, A contact portion 22A in which mountains and valleys are alternately formed is formed.

At this time, the mountain and the valley of the contact portion 22A are connected to each other through a connecting groove (not shown) formed in the guide main body 10 of the other crown guide 2 at a position where one crown guide 2 is rotated by 90 degrees among two adjacent crown guides 2 14).

The engaging portion 22 is provided with a fixing protrusion 22B which is assembled to the fitting groove 12A of the guide main body 10 in a state where a pair of adjacent crown guides 2 are rotated in parallel with each other.

[

In this state, when one crown guide 2 is rotated by 90 degrees, the distance between the side guide bodies 10 is increased as the mountains and the valleys of the contact groove 14 and the contact surface portion 22A are moved to a position where they face each other. And at the same time the engagement protrusion 23B of the fitting insertion portion 23 inserted into the engagement hole 12 is restricted by the engagement protrusion 13 so that the connection groove 14 and the contact portion 22A The latching protrusions 23B are brought into close contact with the latching jaws 13 at a strength corresponding to the force of pushing them against each other.

Therefore, only the assembled crown guide 2 is maintained in a state in which it is assembled in parallel (more specifically, the upper surface is parallel) so that the engaging projection 23B is held in close contact with the engaging jaw 13, The crown guide 2 is kept in a rigid and assembled state.

The connecting groove 14 of the present invention is formed with the fixing groove 15 into which the fixing protrusion 22B of the contact surface portion 22A is inserted so that the contact groove 14 and the contact surface portion 22A, And the fixing projections 22B are inserted into the fixing grooves 15 in a state in which the ribs and the valleys are opposed to each other, and the rotated position is fixed. As a result, the assembled crown guide 2 is prevented from rotating arbitrarily, The crown guide 2 is held while the state in which the engaging protrusion 23B is in close contact with the engaging protrusion 13 is maintained as it is, And the rotation and flow of the crown guide 2 are suppressed, whereby the crown guides 2 to be assembled to each other are effectively prevented from being arbitrarily separated.

Hereinafter, another embodiment of the guide body 10 and the connector 20 according to the present invention will be described.

The connection groove 14 of the guide main body 10 and the mountain and the bottom are assembled at positions displaced from each other by 90 degrees with respect to the mountain and the valley of the contact surface portion 22A when the connection port 20 is fixed to the guide body 10 There is a need.

12 (a), a fitting groove 12A having a predetermined depth is formed along the length of the inner side surface of the coupling hole 12 of the guide body 10 according to the present invention, As shown in Fig. 12 (b), a fitting protrusion 21A having a width and a height corresponding to the fitting groove 12A is protruded from the fixing portion 21.

The guide protrusion 21A of the coupling port 20 is aligned with the fitting groove 12A of the guide main body 10 by the structure of the guide body 10 and the coupling hole 20, (Direction) by merely inserting the engaging hole 21 into the engaging hole 12 of the guide main body 10.

In another embodiment of the present invention, when the crown guides 2 are assembled to each other, a structure for preventing the crown guides 2 from being further rotated beyond a predetermined angle is provided, 13) so as to protrude to one side of the stopper 13A.

In another embodiment of the present invention, as shown in Fig. 13 (b), the inclined surface portion 13B is formed on one side of the engagement protrusion 13 in the direction opposite to the connection groove 14, The engaging protrusion 23B is engaged with the inclined face portion 13B of the engaging jaw 13 when the contact groove 14 and the contact surface portion 22A are rotated so as to face each other, So that the locking protrusion 23B can be brought into close contact with the locking protrusion 13 more strongly.

As described above, according to the present invention, by the engagement protrusion formed on the guide body and the position of the engagement protrusion formed on the connector, the pair of adjacent guide bodies are arranged at 90 degrees to each other, Since the engaging portions formed on the connecting port of the guide body are inserted so as to be close to each other and then the guide body of one side is rotated by 90 ° so that the guide bodies of both sides are parallel to each other, The guide body is not structurally separated, and therefore, the guide body assembled during drilling is basically prevented from being arbitrarily separated by vibration or the like.

Also, since the assembled crown guide does not flow and is rigidly assembled and retained, holes can be formed at precise positions.
