Description of the Invention: [Technical Field] The present invention relates to a drill jig that combines self-locking characteristics and the possibility of locking by means of an auxiliary drill chuck. Further [Prior Art] A drill jig called a self-locking drill jig is known which includes a body adapted to be coupled to a drive shaft and a combined outer casing so that the outer casing can rotate relative to the main body but cannot move axially. The body has a proximal portion projected by the outer casing and a plurality of first handle surface units are formed in the closest portion. The outer casing defines a cavity having a conical inner surface and has a plurality of second handle surface units externally. A plurality of jaws are disposed within the cavity such that the jaws are movable radially and axially to grip the shaft of the bit member or to clamp another tool inserted into the cavity. The push block is guided inside the body so that the push block can move relative to the limb without rotating. The body has internal threads that are coupled to external threads of the push block. The jaws are coupled to a plurality of radial guides formed in the push block and coupled to a plurality of inclined guides formed in a plurality of separate assemblies disposed within the pockets between the jaws. With this configuration, when the body is rotated in the first direction relative to the outer casing, the push block moves axially against the conical inner surface to push the scale so that the tilting is closed by axial and radial movement to close position. When the body is slid away from the outer casing and rotated in the second direction, the push blocks move axially in opposite directions to release the jaws. The push block and the outer and inner threads of the body have a spacing, which is selected to provide a self-locking function of the clamps when the drill clamp is rotated in the first direction, and the first and the outer body and the outer casing The second handle surface unit allows the jaws to be easily released when the body is rotated relative to the outer casing in the second opposite direction by the hand. This mechanism for self-locking the drill bit holder has a more precise advantage than other mechanisms, in which the f-class moves along the body to form an oblique channel and has a tooth portion that is coupled to the outer closure f. The above self-locking function has a lock_advantage' because the larger the resistance of the drill bit or the other tool is, the stronger the lock is. So, but with some drawbacks. For example, 'self-locking iron mask forest is reversible, because when the body rotates in phase-down, the 201200272 clip will automatically become loose, ^ and ^; enough to support the combination of a certain device wiper function, because The clamp is easily released when it is impacted. Also known is a drill bit clamp that utilizes an auxiliary drill chuck wrench having end flanges and pinions to prepare for locking and loosening the jaws. The end guide edge of the auxiliary drill chuck is inserted into the guide hole of the radial drill head wrench formed in the body, the body has inclined passages, and the clamp moves along the inclined passage, and the pinion gear is closed externally. a toothed ring formed in the sleeve, the outer closure sleeve having threads threaded to a plurality of threads formed in the jaws. Such a drill chuck-locked drill bit clamp has the advantage of being reversible and sufficient to support the impactor function, but is not as accurate as self-locking the drill bit clamp. SUMMARY OF THE INVENTION It is an object of the present invention to provide a drill bit clamp that combines the advantages of a self-locking drill bit clamp and a drill chuck trigger clamp. SUMMARY OF THE INVENTION The present invention is directed to providing a general structure having a self-locking iron head clamp and further incorporating a modification to achieve a drill-wrench lock modification to facilitate the foregoing and other objects. The drill bit holder of the present invention comprises: a body adapted to be coupled to the drive shaft; an outer casing that is guided to coaxially rotate the body without axial movement and defining a cavity having a conical inner surface; a plurality of jaws inside the cavity such that the jaws are axially movable between open and closed positions; and are guided to be axially movable relative to the housing and not coaxially rotated against the conical shape The inner surface pushes the push blocks of the jaws. The push block has an external thread that is coupled to an internal thread formed in the body. The body has a plurality of first handle surface units in a proximal portion projected by the outer casing, and the outer casing has a plurality of second handle surface units. The drill jig of the present invention includes two opposing embodiments, although the opposite mechanism is used to make the p-drill wrench fresh. In the first implementation, the couch has a toothed ring in the closest portion projected by the (four) shell, and the outer casing has a radial drill chuck wrench guide hole such that the end guide edge of the auxiliary drill chuck wrench is inserted into the radial direction. When drilling the chuck wrench in the guide hole, part of the auxiliary drill chuck wrench = twisting the toothed ring. In the second embodiment, the body has a melon in the closest portion projected by the outer casing, the hand guide hole is sandwiched, and the outer casing has a ring gear, and the pure non-directional dirty hand guide hole is disposed such that the auxiliary drill When the end flange of the collet wrench is inserted into the guide hole of the radial drill chuck wrench, part of the auxiliary drill chuck of 201200272 will knit the ring gear. Therefore, the drill jig of the present invention can perform normal work by using the plurality of handle surface units described above, whether or not it is required, for example, when the drill jig is screwed; the feed is turned in the opposite direction, or when an impactor is required For function, 2 is used as a standard pan type for the drill chuck with the auxiliary drill chuck wrench. (9) As a result of its high precision and the ability to work in two lying directions, the present invention is particularly necessary for medical applications that are coupled to a manual drive shaft or a drive shaft of a portable or stationary machine. To this end, the net clamp of the present invention can be made of stainless steel, and the handle surface unit can include a plurality of very large and smooth concave surfaces that are distributed over the body and the outer casing to facilitate cleaning and disinfection of the drill head clamp.
