Driving tool

Abstract

The magazine, which is removable from the tool body, is secured to the tool body by fixing screws or a locking mechanism. Conventionally, the user had to loosen the fixing screws or release the locking mechanism before moving the magazine in the removal direction to remove it, which resulted in poor operability. This disclosure improves the operability when removing the magazine. [Solution] The magazine 50 is provided with a locking member 62 for attaching the magazine 50 to the tool body 10, and an operating part 62a that is operated when removing the magazine 50 from the tool body 10 to move the locking member 62 from the locked position to the unlocked position, and the operating part 62a can be operated in an operating direction that intersects both the feeding direction of the driving tool by the magazine 50 and the driving direction of the driving tool. The magazine 50 can be removed from the tool body 10 by rotating it in the removal direction while the operating part 62a is unlocked with one hand.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the driving tools disclosed in Patent Documents 1 and 2, when removing the magazine, the user must move the operating member with one hand along the extending direction of the magazine (on the plane including the feeding direction of the driving tool), and then move the magazine in the removal direction with the other hand. For this reason, conventionally, it was necessary to place the driving tool on a workbench, for example, and perform the magazine removal operation with both hands free. In this respect, the magazine removal operation was cumbersome. The purpose of this disclosure is to improve the operability of magazine removal. [Means for solving the problem]

[0006] According to one aspect of this disclosure, a driving tool includes a tool body for driving in a driving tool and a magazine detachably attached to the tool body for supplying the driving tool to the tool body. The driving tool has a locking member provided on the magazine for attaching the magazine to the tool body. The driving tool has an operating part provided on the magazine for moving the locking member from a locked position to an unlocked position when the magazine is removed from the tool body. The operating part is operable in an operating direction that intersects both the feeding direction of the driving tool by the magazine and the driving direction of the driving tool.

[0007] Therefore, by operating the control unit in the operating direction, the locking member moves from the locked position to the unlocked position, allowing the magazine to be removed from the tool body. This improves the ease of operation for removing the magazine.

[0008] The operating direction of the control unit intersects both the feeding direction of the driving tool by the magazine and the driving direction of the driving tool, and is generally left-right from the perspective of the operator holding the driving tool. Therefore, the operator can, for example, hold the grip 4 of the driving tool with their right hand and the magazine with their left hand, and then operate the control unit to move and remove the magazine. In this way, the magazine can be removed while the driving tool is still in the hand during work, without the need to place the driving tool on a workbench or take other steps, thus improving the ease of operation when removing the magazine.

[Figure 14] This is a longitudinal cross-section of the pusher positioned at the rear end. [Modes for carrying out the invention]

[0010] In one or more embodiments, it has an elastic member that biases the locking member from the unlocked position to the locked position. By operating the operating portion, the locking member moves from the locked position to the unlocked position against the biasing force of the elastic member. Accordingly, the locking member is biased to the locked position by the biasing force of the elastic member. The operating portion is unlocked against the biasing force of the elastic member.

[0011] In one or more embodiments, a guide portion for guiding the magazine in the thickness direction of the magazine is provided on the tool body when the magazine is attached to the tool body. After being guided by the guide portion, the magazine is locked in the locked position by the locking member. Accordingly, the convenience of the magazine attachment work is achieved.

[0012] In one or more embodiments, it has a backlash suppressing member that biases the magazine to suppress backlash of the magazine with respect to the tool body. Accordingly, the magazine is attached to the tool body without rattling.

[0013] In one or more embodiments, it has a cover that covers the backlash suppressing member, and the cover also serves as a guide portion for guiding the magazine when the magazine is attached to the tool body. Accordingly, the usefulness of the cover is enhanced. Also, the number of parts can be reduced as compared with the case where the function as a cover for covering the backlash suppressing member and the function as a guide portion for guiding the magazine are achieved by separate members.

[0014] In one or more embodiments, the cover covers the surface of the tool body and, in cooperation with the surface of the tool body, the cover guides the magazine. Accordingly, the cover that covers the backlash suppressing member also has the function as a guide portion for guiding the magazine. Thereby, an increase in the compactness of the tool body and the number of parts can be avoided.

[0015] In one or more embodiments, the backlash suppressing member biases the magazine in the driving-in direction and the feeding direction. Accordingly, the backlash of the magazine is suppressed in both the driving-in direction and the feeding direction.

[0016] In one or more embodiments, the driving tool can be loaded into the magazine from a loading space opposite to the driving direction. The operating section is located on the rear end side of the magazine in the feeding direction relative to the loading space. Therefore, the operating section is positioned without sacrificing loading space.

[0017] In one or more embodiments, the magazine has a pusher that pushes the driving tool in the feeding direction. The operating part is operablely exposed when the pusher is positioned at its retracted end in the feeding direction. Therefore, the operating part can be operated even when the pusher is positioned at its retracted end.

[0018] In one or more embodiments, the tool body has an engagement portion that rotatably engages with the first end of the magazine. The magazine has a locking member that protrudes from a second end opposite the first end along the tangential direction of the circumference centered on the engagement portion. Thus, the locking member engages more securely with the tool body, stabilizing the magazine's mounting state (locked state by the locking member). [Examples]

[0019] Next, one embodiment of the present disclosure will be described. In this embodiment, as an example of a driving tool 1, a gas spring type driving tool 1 is shown that utilizes the gas pressure of a pressure accumulator chamber as thrust for driving in a driving tool n. In the following description, the case in which the user holds the driving tool 1 in a forward-facing position will be given as an example. Therefore, the driving direction of the driving tool n will be the forward direction, and the opposite driving direction will be the rear direction. The user of the driving tool 1 is located at the rear (generally to the right of the driving tool 1 in Figure 1). The user is used as the reference point for each direction: up, down, left, and right.

[0020] As shown in Figures 1-6, the driving tool 1 has a tool body 10. The tool body 10 has a configuration in which a cylinder 12 is housed in a generally cylindrical body housing 11. The body housing 11 has a split structure that is divided into left and right halves. The left half-housing 11L and the right half-housing 11R are joined together to form the body housing 11.

[0021] A piston 13 is housed within the cylinder 12 so as to be able to reciprocate back and forth. The rear part of the cylinder 12 behind the piston 13 is connected to a pressure accumulator 14. Compressed gas, such as air, is sealed in the pressure accumulator 14. The gas pressure in the pressure accumulator 14 acts as a thrust on the rear surface of the piston 13, causing it to move forward in the direction of impact.

[0022] The front of the cylinder 12 is connected to the driving passage 2a of the driving nose portion 2 provided at the front of the tool body 10. A magazine 50 loaded with multiple driving tools n is connected to the driving nose portion 2. Driving tools n are supplied one by one from the magazine 50 into the driving passage 2a. The driving tools n are supplied in a position that extends in the front-rear direction. A contact arm 3 that is movable relative to the driving nose portion 2 is provided at the front of the driving nose portion 2. The contact arm 3 retracts relative to the driving nose portion 2 by coming into contact with the material to be driven W.

[0023] A long driver 15 is attached to the front of the piston 13. The front part of the driver 15 enters the driving passage 2a. The driver 15 moves forward in the driving passage 2a due to the gas pressure of the accumulator chamber 14 acting on the rear surface of the piston 13. The front end of the driver 15 strikes a single driving tool n supplied into the driving passage 2a. The struck driving tool n is ejected from the ejection port 2b of the driving nose section 2. The ejected driving tool n is driven into the material W to be driven.

[0024] A forward-end damper 17 is positioned at the front of the cylinder 12 to absorb the impact at the forward end of the piston 13. A driver 15 enters the inner circumference of the forward-end damper 17. As the driver 15 reaches the forward end and performs a driving motion, the piston 13 collides with the forward-end damper 17. After the piston 13 collides with the forward-end damper 17 and stops at the forward-end position, the piston 13 and driver 15 are returned to the rear standby position by a lift mechanism 20, which will be described later.

[0025] Multiple rack teeth are provided on the upper surface of the driver 15. Each rack tooth is positioned to protrude upward. The engaging parts of the wheel 28 of the lift mechanism 20, described later, are sequentially engaged with the multiple rack teeth, thereby returning the driver 15 from the forward end position in the driving direction to the rearward standby position.

[0026] As shown in Figure 1, a grip 4 for the user to hold is provided approximately in the middle of the tool body 10 in the front-to-back direction. A trigger 5, operated by the user pulling it with their fingertips, is provided on the upper front of the grip 4. The trigger 5 is activated by pressing the contact arm 3 against the material to be driven W and moving it backward relative to the driving nose portion 2. A battery mounting portion 6 is provided at the bottom of the grip 4. A battery pack 7 can be detachably attached to the underside of the battery mounting portion 6. The battery pack 7 can be removed from the battery mounting portion 6 by sliding it backward relative to the battery mounting portion 6. The removed battery pack 7 can be reused by charging it with a separately prepared charger. Power from the battery pack 7 is supplied to the lift mechanism 20.

[0027] A lower housing 48 is attached to the front of the battery mounting section 6. The lower housing 48 is positioned to protrude forward. A rectangular flat-plate-shaped controller 49 is housed inside the lower housing 48. As shown in Figure 6, the controller 49 is supported in an upright position. The controller 49 primarily controls the operation of the electric motor 30. The upper part of the lower housing 48 is open. The lower part of the electric motor 30 is held in the upper opening 48a of the lower housing 48.

[0028] The lift mechanism 20 is positioned across the area extending to the right and above the driving nose section 2. The lift mechanism 20 has the function of returning the piston 13 and driver 15 together to the rear standby position after impact. When the piston 13 is returned to the rear by the lift mechanism 20, the gas pressure in the pressure accumulator chamber 14 is increased.

[0029] As shown in Figure 6, the lift mechanism 20 is housed in a lift housing 21 located on the right side of the right half housing 11R. The lift housing 21 has a large opening downwards. The opening of the lift housing 21 is closed by the right lift base 22. An electric motor 30 is attached to the right lift base 22. The upper opening 48a of the lower housing 48 is located opposite the opening of the lift housing 21. The electric motor 30 is held between the opening of the lift housing 21 and the upper opening 48a of the lower housing 48.

[0030] The electric motor 30 is supported in a position where the axis of the output shaft 31 (motor axis J) is aligned in the vertical direction. Therefore, the motor axis J is perpendicular to the driving direction (the direction perpendicular to the plane of the paper in Figure 6). The electric motor 30 is powered by the battery pack 7 and started by pulling the trigger 5. The magazine 50 is located along the left side of the electric motor 30.

[0031] As shown in Figure 6, the output shaft 31 of the electric motor 30 is rotatably supported in the motor housing 32 via bearings 33 and 34. A drive bevel gear 35 is provided on the upper part of the output shaft 31. The drive bevel gear 35 meshes with a large-diameter driven bevel gear 36. The driven bevel gear 36 is supported by an intermediate shaft 37. The intermediate shaft 37 is rotatably supported around its axis via bearings 38 and 39. The axis of rotation of the intermediate shaft 37 is perpendicular to the motor axis J and the driving direction.

[0032] The left bearing 38 is attached to the right lift base 22. The right bearing 39 is attached to a disc-shaped cover 40 that is fitted to close the opening of the right lift base 22. A ring-shaped elastic body 41 is interposed between the cover 40 and the lift housing 21. The elastic body 41 absorbs vibrations of the lift mechanism 20.

[0033] A small gear 37a is provided on the left side of the intermediate shaft 37. The small gear 37a is meshed with the large gear 24. The lifter shaft 27 is connected to the large gear 24. A wheel 28 is supported on the lifter shaft 27. When the electric motor 30 is started, the wheel 28 rotates. Multiple engagement points are provided along the periphery of the wheel 28. As the wheel 28 rotates, each engagement point sequentially engages with the rack teeth. This returns the driver 15 from the forward end position to the rear standby position.

[0034] As the wheel 28 rotates, the driver 15 moves further back from its standby position, disengaging from the rack teeth. This causes the driver 15 to advance in the driving direction due to the gas pressure in the pressure accumulator chamber 14 acting on the rear surface of the piston 13. The driving tool n supplied into the driving passage 2a is struck by the advancing driver 15 and driven into the material W to be driven.

[0035] The magazine 50 is detachably attached to the tool body 10. As shown in Figures 7, 8, and 9, the magazine 50 has a base 51 that is a vertically elongated rectangular flat plate. An upper base 52 is attached to the upper part (first end) of the base 51, and a lower base 53 is attached to the lower part (second end). A pusher 54 is supported on the base 51 so as to be movable between the upper base 52 and the lower base 53. The pusher 54 is biased by a coil spring 55 in the feeding direction (upward) of the driving tool n. The driving tool n loaded in the base 51 is pushed towards the driving passage 2a by the pusher 54.

[0036] The pusher 54 can be moved to a lower retracted position against the coil spring 55. The driving tool n can be loaded by moving the pusher 54 to the lower retracted position. As shown in Figure 14, the pusher 54 is provided with a position holding mechanism 56 for holding it in the lower retracted position relative to the base 51. A release lever 54a is provided on the front of the pusher 54. The release lever 54a is supported so as to be rotatable back and forth via a pivot shaft 54b. The release lever 54a is biased to rotate forward by a compression spring 54c.

[0037] An engaging portion 54d is provided on the lower front side of the release lever 54a. The engaging portion 54d protrudes forward. A single engaged portion 51c is provided on the lower front side of the base 51. When the engaging portion 54d engages with the engaged portion 51c from below, the pusher 54 is held in place at its lower retracted end position. When the release lever 54a is pushed backward against the compression spring 54c, the engaging portion 54d retracts backward relative to the engaged portion 51c as a whole. This releases the position holding mechanism 56, allowing the pusher 54 to move upward.

[0038] A box-shaped recess 54e is provided at the bottom of the pusher 54. The recess 54e opens to the left and is enclosed on the front, back, top, bottom, and right side by walls. The user can press the release lever 54a with one finger while hooking another finger into the recess 54e. This allows for one-handed operation of both pressing the release lever 54a and sliding the pusher 54 up and down.

[0039] The lower surface of the engaging portion 54d of the pusher 54 has an inclined surface that slopes downward toward the rear. Therefore, when moving the pusher 54 downward, the engaging portion 54d is pressed against the engaged portion 51c and displaced downward while being displaced backward relative to the engaged portion 51c by the rotation of the release lever 54a. As a result, the engaging portion 54d automatically engages with the engaged portion 51c from below. Therefore, when moving the pusher 54 to the lower retracted end position, the pusher 54 will automatically lock in the retracted end position if a finger is placed in the recess 54e and pushed downward.

[0040] A loading section 51a for loading multiple stapling tools n is provided at the rear of the base 51. The loading section 51a is located in approximately the lower half of the base 51. The thickness of the base 51 is reduced in the loading section 51a. The stapling tool n is a so-called U-shaped tacker, having a head na and two legs nb extending from both sides of the head na. Multiple stapling tools n are loaded into the base 51 from the loading section 51a in a temporarily connected state. The stapling tools n are loaded so that the base 51 is positioned between the two legs nb.

[0041] A protruding portion 51b is provided at the rear of the base 51, above the loading portion 51a. The protruding portion 51b extends linearly from the top of the loading portion 51a toward the driving passage 2a. The position of the protruding portion 51b inside the head portion na helps to maintain the front-to-back position of the loaded driving tool n.

[0042] An engaging portion 52a is provided at the front of the upper base 52. As shown in Figure 8, a coupling shaft 2c is provided at the front of the driving nose portion 2. When the engaging portion 52a engages with the coupling shaft 2c, the front of the upper base 52 is positioned relative to the driving nose portion 2. A projection 52b is provided at the rear of the upper base 52, protruding backward. A rectangular coupling recess 2d is provided at the rear of the driving nose portion 2. When the projection 52b is fitted into the coupling recess 2d from below, the rear of the upper base 52 is positioned upward, backward, and to the left and right relative to the driving nose portion 2. When the upper base 52 is positioned on the underside of the driving nose portion 2, the upper part of the base 51 is positioned along the driving passage 2a. This allows the driving tool n to be smoothly supplied from the magazine 50 into the driving passage 2a.

[0043] As shown in Figure 9, the magazine 50 can be attached to and detached from the tool body 10 by rotating the magazine 50 back and forth (in the direction of arrows M1 and M2 in Figure 9) while the engaging part 52a is hooked onto the coupling shaft 2c from above.

[0044] The magazine 50 is locked to the tool body 10 by a locking mechanism 60 provided on the lower base 53. A rectangular flat base 61 is provided at the rear of the lower base 53. The base 61 has a rectangular retaining recess 61a that opens to the left. The locking member 62 is held within the retaining recess 61a. A guide recess 61b is provided at the upper rear corner of the retaining recess 61a. The guide recess 61b extends diagonally upward and to the rear.

[0045] As shown in Figures 10 and 11, a shaft portion 63 is provided in the guide recess 61b of the base portion 61. The locking member 62 is supported via the shaft portion 63 so as to be able to tilt left and right (in the thickness direction of the locking member 62). The locking member 62 has a rectangular flat operating portion 62a and a lever portion 62b that extends diagonally upward and rearward from the upper corner of the rear side of the operating portion 62a. The operating portion 62a is located in the holding recess 61a, and the lever portion 62b is located in the guide recess 61b. The rear side (tip side) of the lever portion 62b protrudes further rearward from the guide recess 61b.

[0046] An elastic member 64 is interposed between the bottom of the retaining recess 61a and the operating portion 62a. In this embodiment, a compression spring is used as the elastic member 64. The biasing force of the elastic member 64 biases the locking member 62 to displace the operating portion 62a to the left (locking side) and to displace the tip of the lever portion 62b to the right. As shown in Figures 7 and 8, a locking claw 62c and a guide inclined surface 62d are provided at the tip of the right side of the lever portion 62b. The guide inclined surface 62d is provided at an angle to the direction in which the lever portion 62b enters.

[0047] As shown in Figure 12, a locking receiver 70 is provided on the left side of the lower housing 48 of the tool body 10. The locking receiver 70 has a rectangular recess 70a. A ventilation hole 70b is provided at the bottom of the recess 70a. Cooling air from, for example, the controller or electric motor 30 is introduced through the ventilation hole 70b.

[0048] Two wall portions 71 and 72 are provided on the rear side of the lock receiving portion 70. The two wall portions 71 and 72 are integrally provided so as to protrude to the left from the left side of the lower housing 48.

[0049] The upper wall portion 71 extends parallel to the front-rear direction. The lower wall portion 72 extends downward from the rear of the upper wall portion 71. The front surface of the lower wall portion 72 is inclined diagonally upward and forward. A lock recess 73 is provided at the intersection of the upper wall portion 71 and the lower wall portion 72. The lock recess 73 extends diagonally upward and backward with a constant width.

[0050] As shown in Figure 11, the bottom of the lock recess 73 is provided with a claw-hooking portion 73a into which the lock claw 62c of the lock member 62 is hooked. When the lock member 62 is displaced toward the locked side by the elastic member 64, the lock claw 62c engages with the claw-hooking portion 73a and the lock member 62 is held in the locked position.

[0051] When the operating part 62a is pushed to the right against the elastic member 64, the locking member 62 tilts towards the unlocking side around the shaft portion 63. This causes the locking claw 62c of the locking member 62 to disengage from the claw engagement portion 73a. In this embodiment, the operating direction for locking and unlocking the operating part 62a is a direction (left-right direction) that intersects both the feeding direction of the driving tool n by the magazine 50 and the driving direction of the driving nose portion 2 of the driving tool n. Therefore, the user can push the operating part 62a by, for example, pinching it from both sides with the fingertips of their left hand.

[0052] A cover 74 is mounted spanning between the upper and lower wall sections 71 and 72. The rear side of the lock receiving section 70 and the lock recess 73 are covered by the cover 74. When attaching or removing the magazine 50, the left-right position of the lever section 62b of the locking member 62 is guided by the claw-engagement section 73a of the cover 74 and the lock recess 73.

[0053] When the magazine 50 is installed, the lock receiver 70 and the cover 74 function as guides that guide the magazine 50 in the thickness direction. When the magazine 50 is installed, the base portion 61 of the magazine 50 is inserted between the lock receiver 70 and the cover 74. The lock receiver 70 and the cover 74 guide the position of the lower part of the magazine 50 in the left-right direction (thickness direction of the magazine 50) and restrict left-right play of the lower part of the magazine 50 when installed. In addition, when locked, an external force in the leftward direction (unlock direction) is applied to the lever portion 62b from the claw engagement portion 73a (lock recess 73) as a reaction force of the biasing force of the elastic member 64. The leftward external force applied to the lever portion 62b (reaction force of the spring 64) is received by the cover 74. This restricts the displacement of the lever portion 62b in the direction that would disengage from the claw engagement portion 73a, and securely locks the magazine 50 in place.

[0054] A rattle suppression member 75 is provided on the front surface of the lower wall portion 72. The rattle suppression member 75 is supported so as to be displaceable between a position that protrudes from the front surface of the wall portion 72 and a position that is flush with it. The rattle suppression member 75 is biased by a compression spring 76 in a direction that protrudes from the front surface of the wall portion 72.

[0055] As shown in Figure 9, when attaching the magazine 50 to the tool body 10, the magazine 50 is rotated counterclockwise (in the direction of arrow M1) around the coupling shaft 2c of the driving nose portion 2 with the engaging portion 52a engaged. The lever portion 62b of the locking member 62 protrudes along the tangent H direction of the circumference centered on the coupling shaft 2c (engaging portion 52a). The lock recess 73 also extends along the same direction. Therefore, when the magazine 50 is rotated backward around the coupling shaft 2c, the lever portion 62b of the locking member 62 is inserted straight into the lock recess 73.

[0056] The lever portion 62b is indirectly biased by the elastic member 64 toward the side approaching the bottom of the lock recess 73. Therefore, when the lever portion 62b is inserted into the lock recess 73, the guide inclined surface 62d of the lever portion 62b comes into contact with and overcomes the claw hook portion 73a, causing the lock claw 62c to automatically engage with the claw hook portion 73a. As a result, when attaching the magazine 50, the magazine 50 is automatically locked in the attached position by inserting the lever portion 62b of the lock portion 60 into the lock recess 73 without pressing the operating portion 62a. This improves the operability when attaching the magazine 50 to the tool body 10.

[0057] As shown in Figure 10, when the magazine 50 is attached to the tool body 10, the rattle suppression member 75 on the lock receiving portion 70 side is pressed against the rear surface 61c of the base portion 61 of the magazine 50. This causes the biasing force of the compression spring 76 to act on the base portion 61. The biasing force of the compression spring 76 acts in a direction that pushes the rear surface of the base portion 61 forward and diagonally upward. The biasing force of the compression spring 76 presses the magazine 50 against the driving nose portion 2, suppressing rattle. This allows for a smooth supply of the driving tool n from the magazine 50 into the driving passage 2a.

[0058] Furthermore, when the magazine 50 is installed, the rattle suppression member 75 is pressed against the rear surface 61c of the base portion 61 of the magazine 50. When the locking member 62 is unlocked by operating the operating part 62a, the lower side of the magazine 50 is pushed in the removal direction by the biasing force of the rattle suppression member 75. This improves the ease of removing the magazine 50.

[0059] To remove the magazine 50, first push the operating part 62a of the locking member 62 to the right. The pushing operation of the operating part 62a is performed against the elastic member 64. Pushing the operating part 62a causes the locking member 62 to tilt towards the unlocked side around the shaft 63. When the locking member 62 tilts towards the unlocked side, the lever part 62b tilts to the left. This causes the locking claw 62c of the lever part 62b to disengage from the claw engagement part 73a.

[0060] After unlocking the locking member 62 by pushing the operating part 62a to the right, the magazine 50 can be removed from the tool body 10 by rotating it clockwise (in the direction of arrow M2) around the coupling axis 2c in Figure 9. The magazine 50 can be removed, for example, by pushing the operating part 62 of the locking member 62 with the left hand and displacing the lower side of the magazine 50 forward. Therefore, the user can remove the magazine 50 with only their left hand while holding the grip 4 with their right hand.

[0061] As shown in Figure 9, the magazine 50 can be attached and detached with the magazine 50's pusher 54 moved to its lower retracted position. Regardless of the position of the pusher 54, the user can unlock the locking member 62.

[0062] As shown in Figure 13, the driving tools n can be loaded into the magazine 50 while the magazine 50 is still attached to the tool body 10. With the magazine 50 attached, a loading space S is secured behind the loading section 51a for positioning multiple driving tools n to be loaded. The magazine 50 is mounted so as to extend downwards from the driving nose section 2. On the other hand, the lift mechanism 20 is positioned offset to the right relative to the driving nose section 2. This ensures that a loading space S for the driving tools n is secured to the left of the lift mechanism 20. The driving tools n are loaded with their legs nb facing forward, passing through the loading section 51a and straddling the base 51. The loading of the driving tools n is performed via the loading section 51a with the pusher 54 held in its lower, retracted end position. After loading the driving tool n onto the base 51, the position-holding mechanism 56 of the pusher 54 is released (by unlocking the release lever 54a), which pushes the loaded driving tool n towards the driving nose portion 2.

[0063] According to one embodiment, the driving tool 1 has a locking member 62 provided in the magazine 50 that attaches the magazine 50 to the tool body 10. The driving tool 1 has an operating part 62a that is operated when the magazine 50 is removed from the tool body 10 to move the locking member 62 from the locked position to the unlocked position. The operating part 62a can be operated in an operating direction that intersects both the feeding direction of the driving tool n by the magazine 50 and the driving direction of the driving tool n.

[0064] Therefore, by operating the operating part 62a in the operating direction, the locking member 62 moves from the locked position to the unlocked position, allowing the magazine 50 to be removed from the tool body 10. This improves the ease of operation for removing the magazine 50.

[0065] The operating direction of the control unit 62a intersects both the feeding direction of the driving tool n by the magazine 50 and the driving direction of the driving nose portion 2 of the driving tool n, and is generally left-right when viewed from the perspective of the worker holding the driving tool 1. Therefore, the operator can, for example, hold the grip 4 of the driving tool 1 with their right hand and the magazine 50 with their left hand, and then operate the control unit 62a to move the magazine 50 forward (in the direction of arrow M2 in Figure 9) and remove it. In this way, the magazine 50 can be removed while the driving tool 1 is still being held in the hand during work, without the need to place the driving tool 1 on a workbench or take other steps, thus improving the operability when removing the magazine.

[0066] According to the embodiment, the locking member 62 has an elastic member 64 that biases it from the unlocked position to the locked position. By operating the operating part 62a, the locking member 62 moves from the locked position to the unlocked position against the biasing force of the elastic member 64. Therefore, the locking member 62 is biased to the locked position by the biasing force of the elastic member 64. The operating part 62a is pushed to the right against the biasing force of the elastic member 64.

[0067] According to the embodiment, a cover 74 and a locking receiver 70 are provided on the tool body 10 as guide parts that guide the magazine 50 in the thickness direction (left-right direction) when attaching the magazine 50 to the tool body 10. After being guided by the guide parts, the magazine 50 is locked in the locked position by the locking member 62. Therefore, the attachment work of the magazine 50 is made easier.

[0068] According to the embodiment, the magazine 50 has a compression spring 76 as a play suppression member that biases the magazine 50 and suppresses play between the magazine 50 and the tool body 10. Therefore, the magazine 50 is attached to the tool body 10 without any play.

[0069] According to the embodiment, the device has a cover 74 that covers the compression spring 76, which acts as a rattle suppression member, and the cover 74 also serves as a guide that guides the magazine 50 when attaching the magazine 50 to the tool body 10. Therefore, the usefulness of the cover 74 is enhanced. In addition, the number of parts can be reduced compared to when the functions of a cover that covers the compression spring 76 and a guide that guides the magazine 50 are achieved by separate components.

[0070] According to the embodiment, the cover 74 covers the surface of the tool body 10, and the cover 74 works in cooperation with the surface of the tool body 10 to guide the magazine 50. Therefore, the cover 74 that covers the compression spring 76 also functions as a guide for the magazine 50. This makes the tool body 10 compact and avoids an increase in the number of parts.

[0071] According to the embodiment, the compression spring 76, acting as a rattle suppression member, biases the magazine 50 in both the driving and feeding directions. Therefore, rattle of the magazine 50 is suppressed in both the driving and feeding directions.

[0072] According to the embodiment, the driving tool n can be loaded into the magazine 50 from the loading space S in the direction opposite to the driving direction. The operating portion 62a of the locking member 62 is provided on the rear end side of the magazine 50 in the feeding direction relative to the loading space S. Therefore, the operating portion 62a of the locking member 62 is positioned without sacrificing the loading space S.

[0073] According to one embodiment, the magazine 50 has a pusher 54 that pushes the driving tool n in the feeding direction. The operating section 62a is exposed in an operable manner when the pusher 54 is positioned at its retracted end in the feeding direction. Therefore, the operating section 62a can be operated even when the pusher 54 is positioned at its retracted end.

[0074] According to the embodiment, the tool body 10 has a coupling shaft 2c as an engaging part that rotatably engages with the upper part of the magazine 50, which is the first end. The magazine 50 has a locking member 62 that protrudes from the second end opposite the first end along the tangential H direction of the circumference centered on the coupling shaft 2c. Therefore, the locking member 62 is more securely engaged with the tool body 10, and the mounting state of the magazine 50 (locked state by the locking member 62) is stabilized.

[0075] Various modifications can be made to the embodiments described above. For example, although a magazine 50 for loading a U-shaped tacker was given as an example of a driving tool n, the illustrated locking mechanism 60 can also be applied to a magazine for loading rod-shaped nails.

[0076] For example, although a compression spring was given as an example of an elastic member 64 that biases the locking member 62 toward the locked position, a configuration using a leaf spring instead of a compression spring to bias toward the locked position may also be used.

[0077] In this example, the magazine 50 is positioned to the left of the lift mechanism 20 by offsetting the lift mechanism 20 to the right of the drive-in nose section 2. Accordingly, the locking mechanism 60 is unlocked by pushing the operating part 62a of the locking member 62 to the right. Alternatively, the magazine may be positioned to the right of the lift mechanism by offsetting the lift mechanism to the left of the drive-in nose section 2, and the locking mechanism may be unlocked by pushing the operating part of the locking member to the left (left-right reversed).

[0078] Although a gas spring type driving tool was given as an example of driving tool 1, the locking part 60 of the illustrated magazine 50 can also be applied to compressed air type driving tools that use compressed air supplied from an external source as a driving source, mechanical spring type driving tools that use the thrust of a compressed spring as the driving force, or electric wheel type driving tools.
