Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to chucks, and more specifically, it allows operators to control the outer structure of the chuck to rotate reciprocally to a predetermined angle to achieve a drill bit. The purpose of assembly positioning and disassembly. [Previous technology] The chuck structure of the conventional drill bit is generally connected to the power shaft of the transmission device by a body. The body is provided with a plurality of inclined guide holes, and a clamping jaw is provided in each inclined guide hole. A driving ring provided outside the body controls the clamping jaw to advance and retreat in the body, to clamp or loosen a tool, and when the transmission device is started, its power shaft drives the body, the clamping jaw, the driving ring and the tool to rotate synchronously. The above-mentioned chuck structure has an oblique guide hole in the body that is related to the moving direction of the jaw and the force of the clamping tool, so it requires high accuracy and relatively high production cost; and the clamping jaw is clamped on the body of the tool If the working resistance becomes larger, the phenomenon of slipping of the jaw and the cutter is likely to occur. Therefore, many designs for improving the torque of the jaw chuck came into being, but many designs made the chuck structure more and more complicated. Manufacturing costs are also increasing. [Summary of the invention] The technical problem to be solved by the invention: The present invention is to eliminate the problems of the structure of the three-jaw chuck described in the prior art, such as high production cost, increased slippage of the jaw and the cutter when the working resistance increases, and reduced torque. The present invention attempts to overcome the above problems with a structural mode that is completely different from the conventional three-jaw chuck, and achieves the purpose of simplifying the chuck structure, facilitating and rapid bit assembly and positioning, and increasing the torque of the bit. Inventing technical solutions to problems:

Description of the invention (?) The jacket (40) can be seized daily. You can use the bullet, resistance, and clip to know that it has been rotated to a predetermined position. It can also stop the user from turning the needle (20) and the needle. The accommodating portion (3 3) or in addition to the shaped section of the drill bit (80) described above, such as the seventh and eighth (8 11) (8 1 2) such as hexagonal or positive (131) (132) are relative The cross section also reaches the cutter rotation positioning as shown in the ninth figure. The above implementation is replaced, and the long beads (20) of the positioning section (81) cooperate. In summary, the user can unload the drill bit (80) by hand, and the action is reliable. The above-mentioned hole-forming state of the present invention (for example, drilling a cement wall hole) is a scope that can be used without departing from the spirit of the case and the above-mentioned embodiments. Jufan does not apply the spirit of this case. The moving bead (51) moves in the bead groove (53) or (54) of the bead groove (52), and the sound of the pop-up card, and the end wall of the slot (34) and the protrusion (丨 6) move the spin. Move the angle of the outer cover (40) to ensure the relative position of the inclined surface (3 2). The position part (81) and the drilled hole (丨 3) are circular diagrams. The positioning part is a square prism. Of course, the shape of the drilled hole is based on the combined technical function of the polygonal hole column. For example, the roller needle (20) can actuate the beads (201), and the holes (14) can be the bead grooves (14) and the early rotation of the rotating jacket (4〇). It is simple and fast, and the positioning structure of the drill bit (80) is suitable for the description of the best embodiment of the drill that requires low rotation speed and high torque, but it is proficient in making various changes in this technical category. It is clear that this case is not intended to limit the various modifications or changes undertaken in this case.
