The purpose and effect of the present invention is that when the clutch wear piece is relatively coupled with the ridge of the impact ring by the shallow tooth groove, the impact ring is opened in a direction away from the nut to make the nut convex. The teeth are not staggered with the teeth of the impact ring, and the impact ring does not cause any interference with the nut, so that the nut can smoothly rotate with the main shaft and the jaws. The third purpose of the present invention is that when the clutch wear piece is inserted into the tooth ridge of the impact ring with its deep tooth groove, the convex teeth of the nut are interlaced with the convex teeth of the impact ring, and when the nut is worn When the main shaft and the claw rotate, the protruding teeth of the impact ring are pushed, so that the impact ring that is rotated and positioned in the impact shell generates a reciprocating movement in the axial direction, and the nut is repeatedly struck to eliminate the screw 6 200831219 'The hat of the hat (four) teeth and the thread of the Wei _ _, so that _ and the reduction is more tight, and the sew _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Break through the resistance of the drilling surface. The fourth purpose and effect of this case are that the impact shell and the rotating upper shell are all non-moving parts that do not rotate with the main shaft, which is a safety guarantee for the operator. [Embodiment] • In the case of the first and second pictures, the case automatically locks the chuck, which mainly includes: - the spindle (10) 'central setting-shaft hole (10), the fixed end of the drilling tool (10)); the spindle shaft wall a plurality of jaw holes (12) are provided; right right jaws (20) are disposed in the jaw holes (12), and each jaw (2) is provided with a clamping surface (21) and a thread a face (22), the clamping face (2) faces the shaft hole (1)), the thread face ((2) is exposed outside the main shaft (10); - a nut (30), which is sleeved outside the main shaft (10), and has a screw thread therein (8) screwing with the φ thread surface (22) of the central claw (10); _ cap (3 〇) is provided with a plurality of convex teeth (10) on one of the edges; - impact housing (40), fixed to the power source of the chuck The outer casing (not shown) is a stationary component; the impact ring (10) is pivoted outside the upper axle (10) and is rotationally positioned within the impact casing (4〇) with respect to the convex teeth of the nut (30) (32) a plurality of convex teeth (5) and a ridge (52) are provided on the ring surface; a spring (55) is disposed between the impact ring (50) and the impact casing (4〇); the impact ring (5〇) Reciprocating in the impact casing (40) by the spring (55), And the spring (55) causes the impact ring (50) to normally abut the nut (30), and the protruding ring (5) of the impact ring (5〇) is located at the nut (3〇) 7 200831219 Between the convex teeth (32); the ridge (52) is located at the periphery of the nut (30); a rotating upper shell (60), oppositely fitted to the end of the impact shell (40), Rotating by a operator within a limited range; a clutch wear plate (70) is positioned in the rotating upper casing (60) and located at the periphery of the nut (3〇) and with the impact ring (5〇) The ridge (52) is opposite; the clutch wear plate (7 〇) and the rim (in) opposite the rim are provided with a plurality of spaced apart deep cogging (71) and shallow cogging (72); The ridge (52) ^ is located in the deep tooth groove (71), and the convex tooth (51) of the impact ring (10) is located between the convex teeth (10) of the nut (3〇), and the tooth ridge (52) is shallow a tooth groove (72), the impact ring (5〇) is pushed away from the nut (3〇); a set of rotation index (10)), respectively disposed on the surface of the rotating upper casing (10) and the impact casing (4〇) The position of the um is used to indicate that the ridge (10) is located in the deep cogging (9) or the shallow cogging (72). The above is the main technical concept of the present case, which can produce the following functions: · Start the power source of the chuck, the power source drives the spindle (10) to rotate in the direction of action, the jaws (10) on it rotates The threaded surface (22) of the clamping jaw (10) cooperates with the internal thread (31) of the nut (10) to synchronously move the plurality of jaws (10), and the clamping faces (21) of the plurality of jaws (10) generate a to-axis ( 1〇) The clamping force in the axial direction clamps the drilling tool (10)). The clamping jaw (10) can no longer move because the drilling tool (9〇) has been clamped, and the threaded surface (22) and the internal thread (31) of the nut (4) are locked. The nut (10) It only starts to rotate with the cool claw (10). Conversely, when the power source π motion. The main axis (1〇) rotates in the inactive direction, the jaws (10) and the nut (10) are loose, so that the jaws (20) lose their axial direction (1〇). The force is thus released to release the drilling tool (90). It is worthy of special explanation, because the impact shell (10) is fixed to the power source of the cool head of the case. The non-moving part of the lion is not attached to the spindle. The rotating upper shell (4) is positioned at the impact 8 200831219. The outer shell (10) is also A component that does not rotate the shaft (10). Therefore, the impact shell (10) and the rotating upper shell (10) are not touched by the operator, which is a safety guarantee for the operator. As the fifth figure "the operator turns the rotating upper case (10)), the inner clutch wear piece (10) is also rotated by a predetermined angle. When the clutch wear plate (10) is relatively coupled with the ridge (52) of the impact ring (4 〇) with its shallow cogging (10), the impact ring (10) is pushed away from the nut (3 〇). The convex teeth (32) of the nut (10) are not interlaced with the convex teeth (51) of the impact ring (10), and the impact ring (50) does not interfere with the nut _, so the nut (10) is able to follow the main shaft (10) And the jaws (20) rotate smoothly. . As shown in Figures 4 and 6, when the clutch wear plate (10) is rotated with the rotating upper casing (10), it is supplied to the ridge (52) of the impact ring (50) with a deep cogging (71). Embedding, the elastic force of the spring (10) pushes the impact % (5 〇) into the direction of the nut (3 〇), and the convex teeth (32) of the nut (10) are interlaced with the convex teeth (51) of the impact ring (50). In contrast, when the nut (10) rotates with the main shaft (10) and the cool claw (10), it will push against the convex tooth (8) of the impact ring (10), so that the impact (5 〇) generated by the spheroid in the impact casing (10) is generated. The reciprocating movement in the axial direction forms a repeated impact on the nut (10), eliminating the screwing gap between the screw (31) of the nut (30) and the thread surface (22) of the jaw (10), so that the nut (30) ) and the clamping jaw (10) is more tightly locked, and the clamping jaw (10) provides a more stable and tight clamping force of the drilling tool (4), so that the drilling tool (10) can exert the output of the heavy torque and break through the resistance of the drilling surface. Understand the main technical readings of this case, and then introduce the brief details of this case. In the embodiment of the present invention, the impact housing (40) is fixed to the power source 9 200831219 of the chuck to become a stationary member. As shown in the first, second and third figures, the bottom of the impact casing (10) is provided with a shaft (41) for the power shaft to be inserted into the main shaft, and a fan-shaped opening (42) is provided at a peripheral position of the hole (41). - a connecting block (92) is disposed between the magazine (55) and the bottom of the impact casing (10), the connecting block (92) has two protruding connecting columns (10) extending beyond the fan-shaped opening (10), and the end portion is topped Made on the power source housing. The above-mentioned hole (41) is provided with a wear-resistant washer (94) and a positioning member (95) fixed in the positioning groove (14) at the end of the main shaft (10). Even if the main shaft (10) rotates, the impact housing (10) is not affected. Immobile. Regarding the rinsing shell (10), in the case of the residual beam system, the __ring (10) is rotated to the limit. For example, in the third figure, the inside of the impact casing (10) and the impact ring (10) are provided with a relative-bonding limiting strip (43) and a limiting slot (53), the limiting strip (43) and the limiting slot (53). The impact ring (5〇) - is confined to the inside of the flushing shell (10), and the inverted helium can be stably reciprocally displaced in the miscellaneous direction. With regard to the rotating upper casing (60), in the embodiment of the present invention, the clutch wear plate (10) is disposed in a circular direction. As shown in the third figure, the rotating upper casing (10) is screamed to support the clutch wear plate (7)) φ the saddle layer (61); the outer wall of the rotating upper casing (60) and the outer portion of the clutch wear piece (7〇) The limiting strip (62) and the limiting slot (73) are relatively coupled, and the limiting strip (10) and the limiting slot (73) cause the clutch wear piece (10) to be rotated to be limited to the rotating upper shell (6_ The part will therefore rotate with the rotating upper casing (10). The level (61) axially positions the clutch wear plate (10) in the rotating upper casing (60) opposite the impact ring (10). With regard to the rotating upper casing (6〇), in the embodiment of the present invention, the end of the impact casing (4〇) is rotated by the operator within a limited range. For example, in the second, third, sixth and seventh figures, the outer surface of the impact is provided with two elastic groove (44) (45), and the inner wall of the rotating upper casing (10) is embedded with a bow-shaped elastic piece 200831219 (10) 'the bow convex portion can be embedded The shrapnel groove (9) is rotated by the rotating casing (10) to be separated from the shrapnel groove (10). When the bow-shaped elastic piece (10) is located therein - the elastic piece groove (10), it indicates that the ridge (52) of the impact ring (50) is embedded in the deep tooth groove (8) of the clutch wear piece (7G), and the impact ring ((6) will be as above The nut (10) is repeatedly struck against the ground, as shown in the fourth figure. When the bow-shaped elastic piece (10) is located in the other elastic piece groove (45), it indicates that the ridge (52) of the impact ring (50) is oppositely coupled to the shallow tooth groove (72) of the clutch wear piece (7〇), The wire loop (5 inch) sugar nut (10) causes interference, as shown in the fifth figure.
