For example, a spiral impulse suppression and offset device 36 is configured to offset the suppressor 1 90 against a step between the large diameter portion 41 〇 and the middle diameter portion 4 2 0 of the sleeve wall. Two degrees. The first displacement suppressing ball 390 is arranged in the second radial hole 395. The second radial hole 3 95 has a geometry corresponding to the first radial hole 3 30 to limit the movement of the first restraint displacement ball 3 90 to the movement corresponding to the lock ball 17 0. A second displacement suppressing ball 400 is arranged in the third radial hole 405. The second radial hole 405 has a geometry corresponding to the first radial hole 301, to restrict the movement of the displacement ball 400 to the movement corresponding to the lock ball 170. The radii of the first, second and third radial holes are substantially the same. The second radial hole 395 is disposed in the depth direction of the elongated connector device 110 ′, and at a distance from the first radial hole 130 corresponding to about half the radius of the radial holes, and the third radial hole The hole 405 is arranged in the depth direction of the slender connection device 1 and 10, and at a distance from the first radial hole 395 corresponding to the large, half-spooned half corresponding to the radial holes. Therefore, the radial holes are arranged circumferentially on the outer side of the slender connector device 110, which corresponds to a half-to-back staggered position corresponding to a half radius of the radial holes. This is advantageous for the first and second The displacement suppressing balls 39, 400 are respectively arranged in completely relative positions, so two first displacement suppressing balls are used and two first displacement suppressing balls are used. In this way, the suppressor can achieve smooth and more reliable movement. See FIG. 11A and FIG. 11B.

Explanation of the invention (23) Therefore, the first restraint displacement ball 390 is pressed against the lock ball suppressor 190, forcing the ball suppressor 190 toward the tool holder 10. As shown in FIG. 12A and FIG. 12 β, when the tool drill 300 is further depressed, the seat 3 of the tool drill 300 hits the second suppression displacement ball 400 ′, and the suppression The displacement ball was pressed out of the third radial hole 405. Therefore, the second restraint displacement ball 400 is pressed against the lock ball suppressor 90, forcing the lock ball 190 further toward the tool base 10. σ is now at a position on the lock ball 170. Moreover, the downward movement of the tool drill 300 will cause the seat 3 of the tool drill 300 to collide with the lock ball 170, and the lock ball will be pushed out of the first radial hole 13, as shown in Figure 13a and Figure 13 Thirteen B is shown. Therefore, the lock ball 丨 70 will be pressed against the lock ball suppressor 190, forcing the lock ball suppressor 丨 90 to move further toward the tool holder β to a position of the lock ball suppressor. When the tool bit 300 is pressed Further pressing, this position allows the lock ball to completely exit the deep hole 120, as shown in Figures 14A and 14B. In Fig. 15A and Fig. 15β, it is shown that the position of the device immediately before the lock ball 170 is in the circumferential groove 330 entering the tool drill 300.

In Figures 16A and 16β, the tool bit 300 is fully inserted and the lock ball 170 is fully seated into the circumferential groove 330 in the tool bit 300. Now the ball lock suppressor 19 is in the lock ball. At a position on 17 °, the lock ball can be effectively positioned and locked. Therefore, the tool drill bit 300 is held in the middle. In order to release the tool drill bit 300 from the grip 100, the outer sleeve 180 is pulled back toward the tool holder 10 and moved from the position on the lock ball 70 to Ball lock suppressor °

Description of the invention (25) One of 30-substantially spherical lock ball 17, as it is related to the present invention = As described in one embodiment. When the tool drill 300 is fully inserted into the grip 〇00, the lock ball 170 cooperates with the circumferential groove of the tool drill 300 to position and lock the tool drill. The outer sleeve 1 87 is arranged to slide on each other on the connector device 111 between the positions of the two end portions, and has a stepped inner diameter having a face; a middle diameter portion 188 of 100; and The tool drill 300 has a large-diameter portion 189 with a small-diameter portion 198 in the middle. A spherical groove 172 is arranged in the small direct control portion 198+, and the groove m has a shape conforming to the spherical surface of the lock ball 170. For example, a helical spring deflection suppressing device 200, is arranged in the portion 189 to offset the outer sleeve m away from the pedestal seat 1 () and thereby the spherical groove 172 away from the lock ball 170. A ring-shaped offset device baffle 5 is arranged at the end of the connector device 11 and faces the tool bit ⑽0 to prevent the sleeve offset device from falling from the sleeve and to provide a supporting surface for the offset device. An angled channel 112 is arranged on the connector device 11! Between the first radial hole 130 and the end of the connector device facing the handle 100. The angled channel and the radial hole are connected by a connecting channel 3, which is arranged on the side of the connector facing the sleeve. An elongated rigid arm 171 is arranged in the angled passage 112, so that the rounded end portion 173 of the hard arm 171 is pushed into the connection passage 113. When the tool-less drill bit 300 is fully inserted into the deep hole 21 and the outer sleeve 187 is offset, and its position is closest to the tool seat i 0, the slender rigid arm i 7 is a passage freely at a certain angle. 112 moves, but because the outer sleeve 187 and the bottom of depth = 2! Block its movement, the slender rigid arm 171 cannot move out of the channel. The β-rounded end 173 is placed in the #near spherical groove 172 or the ball 526107 V. Description of the invention (26) The surface groove 172 is in this position of the sleeve. When a tool drill 300 is inserted into the grip 100, the outer sleeve 1 8 7 is in the position shown in FIG. 19, and the rounded end 1 73 of the hard arm 1 7 is further blocked. The sleeve moves towards the tool holder 10 '' '. When the insertion end of the tool drill 300 contacts the hard arm 171, the hard arm 171 is tilted away from the stop edge 183, which is arranged on the inner side of the outer sleeve 1 8 7 so as to be locked against this by the hard arm The edge of the stop is no longer blocked during its offset movement away from the tool bit 300. Therefore, 'the sleeve will slide away from the tool drill 300 and the lock ball 丨 70 will be pressed into the circumferential groove of the tool drill 300, and the tool drill 300 will be firmly positioned and locked' as shown in Figure 19 As shown. When the tool bit 3 00 is fully inserted, it is shifted by the sleeve offset device 200 by the sleeve 187, and the tool bit 1 is shifted away from the tool seat 1 0 so that the lock ball 17 is seated in the tool bit 3 without restriction. 〇〇 In the circumferential groove 0 In order to loosen the tool bit 3 〇〇, the outer sleeve 丨 8 7 slide away from the tool seat 1 0 ′ whereby the small diameter portion of the outer sleeve 1 8 7 1 8 no longer blocks the lock ball 1 70's movement in radial holes. The rounded end of the rigid arm 71 is slanted against the edge of the stopper arranged on the inner side of the outer sleeve 1 87, so that the hard arm is locked against the edge of the seeding part, away from it. The tool bit 3 blocked the sleeve during the offset movement. Therefore, the spherical groove 丨 7 2 is directly located on the lock ball 丨 7 〇. Therefore, the tool bit 3 00 can be removed from the deep hole 2 0,, as shown in FIG. 19. A fourth embodiment of the present invention is shown in FIGS. 10 to 25B. The connection device 1 1 0 ′ ’′ includes a deep hole 丨 2 2 and an opposite tool holder ίο’. The connector device 110, further has 526107 in the seat of the deep hole 122. V. Description of the invention (27)

The substantially cylindrical enlarged portion of the deep hole 丨 2 3. A deep incision 丨 7 7 is arranged along the enlarged portion of the deep hole 1 2 3 and a penetrating hole 1 7 8 is arranged opposite to the deep incision 1 ^ 7. A washer 176 has a substantially circular circumference, a short radial projection 1 6 1, and a long radial projection 62.

When the device is being assembled, the first projection 161 is inserted into the through-hole 1 7 8 and the second projection 1 62 is inserted into the deep incision 1 7 7. The outer sleeve 202 is shifted away from the tool holder 10 by a sleeve biasing device 201, which is pressed against the sleeve through the second protrusion 162 of the washer 176. The outer diameter of the washer 1 7 6 is smaller than the inner diameter of the enlarged portion 1 2 3 of the deep hole 1 2 2. The loop 1 76 prevents excessive tilting by engaging the first projection 丨 6} with the through hole 78 and the second projection 162 with the deep incision 1 7 7. The sleeve 202 has a side entry hole 203 on its end facing away from the tool holder 10 '. The entry hole 203 is aligned with the inserted tool drill bit 300, and its cross-section has a cross-section corresponding to the entry hole, a deep hole 丨 2 2 and a central hole 1 79 of the washer 丨 7 and a central hole of the washer and Deep hole, as shown in Figure 20.

In FIG. 11 ', the tool bit 300 has a contact ring 176, so that the ring 176 is aligned with the outer side of the tool bit. Therefore, during the insertion of the tool bit 300, the washer is forced to tilt less to fit the tool bit inside the center hole 17 of the washer 17 6. During insertion, the sleeve offset setting 2 0 1 was also slightly compressed. When the tool bit 3 is completely inserted into the depth

In this manner, the tool bit 3 0 0 is held inside the circumference of the center hole 1 79 of the washer 17 6 to prevent the tool bit 3 0 0 from being removed from the depth hole 1 2 2. In order to release the tool bit 300, the sleeve 202 will have to be pressed against the tool grip 10. Then the second protrusion 1 6 2 of the washer 1 7 6 will be pressed in the same direction · 'to make the washer less inclined. Therefore, the grip of the washer on the tool bit 300 is reduced, and the tool bit 300 can be removed. A variation of the fourth embodiment of the present invention is shown in Fig. 47.

The turning ball 194 is arranged in a turning hole 195 in the connector device 11 4 '. The turning hole is actually radial, and preferably, it is inclined at an angle, so that the bottom of the turning hole 95 is arranged deeper from the tool base 10IV than the turning hole top 195. Alternatively, the turning hole is actually perpendicular to the deep hole 120 IV. Therefore, the diameter of the turning ball 194 substantially corresponds to the diameter of the turning hole 195, and the first position of the turning hole bottom 195 ' The chamfered turning portion 1 8 6 is pressed against the turning ball 丨 9 4 by the sleeve offset device 3 6 0 ′ ′. ^ In Fig. 29A, the tool drill 300 is held in the position of 'inserted into the grip'. The lock ball 170 is freely located in the radial hole 130, and the large-diameter portion 193 of the intermediate cylinder biasing tube 184, 'is located near the lock ball 170.
