Cummins, PCT/US2000/009080 (WO 2001/017728), describes a hand drill having a drive shaft and can be 45 about an axis of rotation relative to the drive shaft. Set the axis to manually rotate the knife table. The turrets have 90 each other. Two collets are provided which are spaced apart at an angle with respect to the axis of rotation of the turret. The user of the drill bit can load each chuck with a drill of the appropriate size so that each drill bit can be used sequentially for specific operations requiring the use of two drill bits. In order to interchange the drill bit, the user must hold the hand grip of the drill bit with one hand and manually rotate the turret 180 after disengaging the drill bit from the first collet that is currently in use. . This operation delivers the second collet and corresponding bit to the use position where the user can selectively re-engage the drive shaft with the second collet to facilitate use of the drill bit. In many cases the user of the drill bit cannot liberate his hands. If not both hands are free, the user cannot replace the collet and the drill bit without risking certain risks. This occurs when the user is standing on a ladder with a hole above the top of the drill head above the ground level. In order to change the bit position using the tools described above in the prior art, the user must pull down the ladder and then manually rotate the table, then climb the ladder again to continue using the drill with the new bit in place. Accordingly, it is an object of the present invention to provide a hand held tool, preferably a hand held drill, comprising a plurality of drill jigs mounted on a turret, the drill jigs being selectively replaceable to a use position, respectively No need to use the operator's hands. SUMMARY OF THE INVENTION H5054.doc 1301427 According to the present invention, there is provided a tool comprising a plurality of drill jigs that are interchangeable with each other in use in front of the tool, the drill jigs being mounted at an angularly spaced apart position on the tool table The turret is rotatable about an axis set at an angle relative to a rotational axis of the drive shaft, the drive shaft reciprocating between the first and second axially spaced positions, the drive shaft being divided into two The position is engaged with and disengaged from the bit holder in the use position, wherein the positioning of the drive shaft in the second position establishes a drive connection between the drive shaft and the table, so that the subsequent operation of the drive shaft rotates the table to replace the The position of the bit holder in position is used, wherein the drive shaft is adapted to return to its first position after the table has been rotated and to resume driving connection with the new bit holder in the position of use. Preferably, the turret has a height of substantially 45 with respect to the axis of the drive shaft. ' Set the axis of rotation and install two drill clamps. This arrangement is particularly useful in the case of tools with a pistol grip because it allows the bit holder that is not in the position to occupy the storage position in front of the hand grip. Preferably, the tool also includes at least two triggers for controlling the operation of the tool, the first trigger being selectively operable to generate rotation of the drive shaft, and the second trigger being selectively operable to The drive shaft reciprocates between its first and second axially spaced apart positions. Preferably, the trigger is disposed on the hand grip portion of the tool. In a preferred embodiment, the drive shaft has a pinion that is in a non-functional position when the drive shaft is in its first position and that moves to the pinion when the drive shaft is in its second position Set on the turret 115054.doc 1301427 where the drive shaft is in the position of the drill bit of the subsequent rotary position or mesh with the ring gear integrated with the turret, the turret is rotated, and the interchange is in use. In the preferred embodiment of the invention, the actuation of the drive shaft to its second position is achieved by having the drive shaft in its second position. Preferably, the electromagnetic coil is disposed by the second trigger, and the rotation of the turret selectively activates the first trigger. In a preferred embodiment, the drive shaft has a pinion gear. The pinion is in a non-functional = set when the drive shaft is in its first position and moves in engagement with a gear that is placed within the turret when the drive shaft is in its second position, wherein the drive shaft is subsequently rotated The turret is rotated and thereby swapped the position of the drill bit in the position of use. In a possible preferred embodiment of the alternative, preferably, the second trigger is in a mechanism that applies a force to it mechanically to move the drive shaft to its second position 'when the second trigger has driven the shaft When the motion is moved to the 1st position, the sensor or switch is activated, which causes the drive shaft to rotate and thereby rotate the table. In a preferred embodiment, the tool is a battery powered drill and the drill chuck is a drill chuck. [Embodiment] Any suitable form of hand-held tool 10 is shown in Figures 1 to 5f, such as an electric drill as shown. Although an electric drill is shown in the figures, it will be understood that the hand tool 10 can be implemented in many other forms, and thus the present invention is not limited to the particular embodiment shown. 115054.doc 1301427 In particular, in time u, it can be seen that the hand tool 1G is constructed as a drill having a body housing 12 with a grab grip portion 14 and a hand tool 10 (hereinafter referred to as, The user of the drill 10") (not shown) can comfortably hold the hand tool 10 with one hand. The speed control slider or switch 16 allows the speed of the drill 1 to be changed to suit the drill to be drilled. Different materials (not shown). The pistol grip portion 14 has an enlarged base 18 for charging a rechargeable battery (not shown) into the drill 10. The two trigger switches 2, 22, respectively The power supply of the drill 10 is 〇N/〇FF switch (2〇) and the chuck replacement switch (22). Although not shown in the drawing, as an alternative to using a rechargeable battery as a power supply device, the drill 1 can be The AC power source is used to supply power, or it may be a pneumatic or hydraulic drill device. It should therefore be understood that the invention is not limited to the particular embodiment described. The front end of the body housing 12 is provided with a rotatable turret 24 on which two drills are mounted With collets 26, 28. It should be understood that if necessary More chucks are provided, so the invention is not limited to the particular embodiment provided. The collets 26, 28 have respective axes of rotation 30, 32 and are capable of different tool bits 34, 36 (such as the drill shown in the figures) Mounted on the respective chucks %, 28 shown. The body housing 12 houses the motor 38 powered by the on/off switch 2A of the battery of the tool 1 ,, also accommodated by the speed control switch 16 and the motor 38 The drive is transmitted to the reduction gearbox 4 of the drive shaft 42. As shown in Figures la and lb (and the top views of Figures 2a and 2b), the drive shaft is interchanged when the chucks 26, 28 are interchanged at the forward end of the drill 10. 42 can be axially reciprocated between two axially spaced apart positions by the collet change switch 22. The clamps 115054.doc 1301427 are mounted in respective connectors 44, 46, the connectors It is rotatably mounted on the turret 24 such that its axes 3, 32 are set at an appropriate angle to each other, such as substantially 9 〇 in the figure. Each connector 44, 46 has a central rear socket (not shown) Show that the central rear socket has an open entrance for The movement of the moving shaft 42 to the first or engaged position (see, for example, Figures la and 2a) directs a complementary shaped plug structure (not shown) formed on the forward end of the drive shaft 42 into the central rear socket. In particular, the position of the collet 26 in Fig. 1a), the plug structure of the drive shaft 42 can be mated with the central rear socket of the connector 44 so that rotational drive from the drive shaft 42 is transmitted to the front end of the drill 10. Connector 44 and collet 26. Drive shaft 42 is resiliently biased toward its engaged position (Figs. 1a and 2a) by a spring or any other suitable means (not shown) in which the plug structure and the drill are At the end of the 10th, the central rear socket of the connector 44 is sprayed. The operation of the solenoid 48 moves the drive shaft 42 to a second or disengaged position against the bias of the spring (see, for example, Figures lb and 2b) which is axially separated from its spray position (see Figures 1a and 2a). And in the disengaged position, the plug structure at the end of the drive shaft 42 is retracted from the center of the connector 44. It should be understood that instead of using a spring or similar device (not shown) to return the drive shaft 42 to its engaged position, the drill 10 can simply perform the same action using a double acting solenoid or similar device (not shown), thus The invention is not limited to the specific embodiments provided. The turret 24 is mounted such that it rotates about the axis 5〇 after the plug structure of the drive shaft 42 has been retracted from the connector 44 to its disengaged position (see Figures 1 & ib). The axis 50 is preferably disposed 45 as opposed to the axis of the drive shaft 42 as shown. 115054.doc -10- 1301427 Angle, but can be set to any suitable angle, both axes preferably located in the same plane as the longitudinal axis of the hand grip portion 14. The turret 24 is rotated to change the position of the collets 26, 28 by the operation of the mechanism 52 shown in more detail in Figures 5a through 5f (described later). In Fig. 5a, it can be seen that the mechanism 52 of the drill 10 includes a toothed circular rack or ring gear μ concentric with the square pivot axis 50 of the turret 24, which is coupled or integrated with the turret 24. . The drive shaft 42 has a bevel gear or pinion 56 that is disengaged from the engaged position of the drive shaft 42 from its engaged position along arrow a (see Figure 5b) due to the selective operation of the solenoid 48 in response to the collet change switch 22. Movement, the bevel gear or pinion 56 is spouted with the ring gear 54. The upper peripheral edge or surface of the ring # wheel 54 is provided with two chevron blocks 58, as shown in Fig. 5a, which are disposed on opposite sides of the axis 50 which are diametrically opposed, and which are respectively provided with a pair of opposite inclined faces. Blocks 58 are each positioned to cooperate with rocker 60. The rocker 60 includes two parallel arms 62 (see top views of Figures 2a, 2b and 3) that have strips or bridges 64 that connect a pair of ends 66. The bridge 64 includes a smooth lower surface that abuts the upper peripheral edge of the %-shaped gear 54 during operation of the mechanism 52. When the ring gear 54 is rotated by the pinion 56, the opposite inclined surface of the block 58 acts on the bridge 64 of the rocker 6 (see Fig. 5d). The other pair of ends of the parallel arms 62 "terminate to the respective pawl 70. When the rocker 60 is in its rest position (shown in solid lines in Figures 5a, y, & and 5f), the pawl 70 is in the ring The teeth of the gear 54 are engaged. The rocker 60 is mounted on a pin 72 that is mounted in a bushing (not shown) that allows the pin 72 to rotate about its axis. The lower side of the pin 72 is parallel 115054 .doc • 11 - 1301427 There is a section (4) between the arms 62 with teeth on the underside as shown, and the Deng 74 is preferably provided on its upper surface or with the upper surface. • 7 integrated cover (not shown). The cover accommodates the lower portion of the wound compression spring 76: the end 'this spring is preferably held inside a straight tube (not shown). As shown in the "to 4" factory, the rocker The upper end is coupled to the body-housing 12 at a thrust bearing 78 by a lock 72. Rocker 60 is biased by portion 74 and spring 76 to its rest position. The toothed lower surface of the portion μ provides an eccentric device (〇ver_centering deV1Ce) that cooperates with the spring 76 to hold the rocker 60 in one of the two stationary positions (Figs. 5a, 5b, 5e). And 5 f), the other is the disconnected position (Figures 5c and 5d). When the pinion gear 56 engages with the break block 78 fixed to or integrated with the lower surface of the parallel arm 62, the rocker 60 is switched to the direction of the arrow arrow ^ (see Fig. 5c) Disconnected, position, because pinion 56 is pulled in the direction of arrow a to anneal to ring gear 54. When the lower surface of the bridge 64 engages with the chevron block 58 and is pushed upward by it, the rocker 60 returns to its rest position in the direction of arrow b (see Figs. 5d and 5e) because the ring gear 54 is small A gear 56 (which rotates in the direction of arrow d as the drive shaft 42 rotates) rotates in the direction of arrow c. 1 The use of the drill 10 and the selective automatic rotation of the drive shaft 42 and the connector 44 in response to the activation of the collet change switch 22 are described in more detail below with particular reference to Figures 5a through 5f (Figures la and 2a). As shown, when the position corresponding to the internal components of the drill 10 shown in Figure 5a is engaged, one of the user's hands can be utilized to selectively operate the ΟΝ/OFF trigger switch 20 (using the clamp 115054.doc - 12- 1301427 Head 26 and corresponding drill bit 34) for drilling holes above the head. If necessary, the drill is operated while the user is standing on the ladder held by the other hand. The operation of the ΟΝ/OFF switch 20 completes a circuit (not shown) between the battery (not shown) and the motor 38, which supplies the drive shaft 42 with an output drive transmitted by the gearbox 40. The drive shaft 42 rotates at a speed determined by the depth of compression applied to the on/qff switch 20.

When the ΟΝ/OFF switch 20 is released, the circuit leading to the motor 38 is disconnected, which causes the rotation of the drive shaft 42 to stop. Then, by selectively pressing the collet replacement switch 22, the user can interchange the positions of the collets %, 28 as needed. The chuck replacement switch 22 is pressed to supply power to the electromagnetic coil 48. When the plug structure (not shown) of the electromagnetic coil and the guide shaft of the drive shaft 42 is retracted from the connector 44, the drive shaft is driven from the / position. Reciprocating toward its disengaged position (Figs. 5c to 5e) in the direction of arrow a (Figs. 5b and 5c). The movement of the drive shaft 42 to its disengaged position causes the pinion 56 to engage and push the rocker 6's break block, which causes the rocker 6 to move from its resting position in the direction of arrow b (Fig. 4) The movement to its disengaged position rocker 60 to its disengaged position causes the upper peripheral edge of the lower surface of the bridge member to engage. At the same time, the rotation of the rocker (9) will be parallel arm 62 at the end 68. The pawl 7〇 is raised outside the slit between the teeth of the ring gear 54, and the pinion 56 meshes with the ring gear 54. The user of the 4th, while the finger is continuously pressing the chuck to replace the switch 22 Press 〇N/〇FF trigger switch 2〇 with another finger. All these operations can be performed by Tian Tiantian ^ ^. The household is used again and again, so that the other hand is 115054.doc -13- 1301427 Free to continue to support itself on the ladder. The second press of the ΟΝ/OFF switch 20 acts to re-energize the motor 'but this time' its rotational drive is transmitted by the drive shaft 42 and the pinion %, Rotate the knife clockwise along arrow c (see Figure 5d). The position of 26, 28 (see the figures shown in Figures 3 and 4: middle = set) 'until the turret 24 has been rotated approximately 18 在 in this embodiment, so that the connector 46 of the collet 28 and the drive shaft 42 The front end is almost opposite so that its plug structure (not shown) is approximately aligned with the open opening of the connector 46. The human block 58 is thus positioned on the ring gear 54 of the turret 24, i.e., when this = occurs When the lower surface of the bridge 64 is covered by the inclined surface of the block 58, the inclined surface forces the bridge 64 of the rocker 6 () to be upward, which pushes the rocker 6 = arrow b' direction (Fig. 5e) back to Its resting position. When the pawl 70 of the parallel arm 62 on the end 68 is opposite (not engaged) with the corresponding tooth of the ring gear 54, the bridge 74 is overcome by a small upward movement of the spring bias of the spring 76 by the portion 74. The rise of the member 64. The rotation of the turret 24 is unobstructed and continues until the pawl 70 is aligned between the teeth of the ring gear 54. The pawl 70 then falls into the middle of each tooth to prevent the turret 24 Further rotation. At this time, the plug structure (not shown) and the plug at the front end of the drive shaft 42 The open ports of the members 46 are opposite and spaced apart. The chuck change switch 22 can then be released to disconnect the power to the solenoid 48. The drive shaft 42 can then act in the direction of the arrow a' (Fig. 5f). The spring-biased thrust on the shaft 42 reciprocates back to its engaged position. During this movement, the plug structure is guided into the insert 46 (if desired by opening the inlet). 26, 28, the user can release 〇n / 〇 FF open 115054.doc -14 - 1301427 off 20, and press the chuck replacement switch 22 as before. Then disconnect the power supply to the motor 38, touch the electromagnetic coil 48 to drive the drive shaft 42 (in the direction of arrow a) and return to its disengaged position. The turret 24 can then be rotated 180 by operating the two switches 20, 22 together. Or, depending on the number of chucks and any suitable angle of their positioning, the procedures already described can then be repeated. In Figures 6 through 7d, there is shown any suitable form of hand held tool 10 manufactured in accordance with a second preferred embodiment of the present invention, such as an electric drill shown. In Figs. 6 to 7d, the same reference numerals correspond to the similar portions shown in Figs. The tool 1〇〇 (hereinafter referred to as "drill 1"") of Figures 6 to 7d differs from the drill 10 of Figure las5f in that the drive shaft 142 is in its engaged position (Figures 6 and 7(1) and The manner of movement between the disengaged positions (Figs. 7a to 7c), and the components of the mechanism 152. These main differences are discussed below. In Fig. 6, similar to the drill 1〇 in Figs. ia to 5f, it can be seen that the drill The drive shaft 142 with the 100 is resiliently biased by the magazine 18 (or other suitable means) to its engaged position 'in the engaged position, its plug structure 182 and the rear socket 184 of the connector 144 at the forward end of the drill 1 〇〇 Engagement. Instead of using the electromagnetic coil to move the drive shaft 142 to its disengaged position, the drill 1 of Figures 6 through 7d utilizes a mechanical trigger mechanism that acts as a collet change switch 122 for the drill 100. Chuck replacement trigger The 122 is pivoted relative to the pin 186 in the direction of the arrow 乂 and x' (see Figure and 7d). The chuck replacement trigger 122 is in the parked position when the drive shaft 142 is in its engaged position (see Figures 6 and 7 when The chuck replacement trigger 122 moves to the starting position when the drive shaft 142 moves and is in its disengaged position (See FIGS. 115054.doc -15. 1301427 see Figures 7a through 7c.) In response to the force applied to the collet replacement trigger 122, when the collet replacement trigger 122 is moved in the direction of arrow X to its activated position The drive shaft 142 is moved from its engaged position in the direction of the arrow a to its disengaged position. The upper portion of the collet replacement trigger 122 acts on a projection 188 disposed on or integral with the drive shaft 142. The collet replacement trigger 122 is configured to pull the drive shaft 42 into its disengaged position in the direction of arrow a when a force is applied. When the collet replacement trigger 122 is released from its activated position, the magazine 180 The collet replacement trigger 122 is returned to its rest position in the direction of arrow xf (Fig. 7d) while the spring ι8 〇 returns the drive shaft 142 to its engaged position in the direction of the arrow ^. The peripheral edge of the rear surface 122 is an extension 19 that is arranged in such a manner that when the collet replacement trigger 122 is forced into its activated position in the direction of arrow X, the opening switch 192 is activated by the extension 190. The opening switch 192 is activated. Completed in electricity A circuit (not shown) between the pool (not shown) and the motor 138 of the drill 1 (9). When power is supplied to the motor 138, the drive shaft 142 rotates in the direction of the front head d (see Figure 7b), which results in a knife The table 124 rotates in the direction of the arrow c because the pinion 156 is engaged with the mechanism 15 2 of the drill 1 (10) in the disengaged position of the drive shaft 142. Unlike the case of the drill 1〇 in Figs. la to 5f, the drill The mechanism 152 is a simple gear 154 disposed in the turret 124 that engages and drives the gear 154 by the pinion ι 56 as the drive shaft 142 rotates in the direction of arrow d (Fig. 7b) and is in its disengaged position. As a drill 1 in Figures 6 to 7d having a mechanism 152 utilizing a rocker setting (60) that correctly positions the collets (26, 28) in the respective use positions of the collets, as in Figure 1 & The tool 100 utilizes an inductor or switch (not shown) that can detect when the knife σ 124 is correctly aligned with the collets 126, 128, in the case of the drilling tool 1 〇 115054.doc -16- 1301427. Precisely, the drive shaft 142 can be moved back to its engaged position in the direction of arrow a when the collet replacement trigger 丨 22 is released.
