作によりねじ保持ベルトが−ねじ区間だけ移送される。As shown in a conventional example in FIG. 13, this screw driving device has a cylindrical sliding guide case 73 attached to the tip of an electric screwdriver tool 7l via a connecting member 72, and a sliding member into which a screw holding belt is loaded. 74 is fitted into the case 73 via a return spring 75 so as to be vertically slidable. The belt loading portion of the sliding member 74 is provided with a sprocket that engages with the screw holding belt and a ratchet wheel that engages with the sprocket. This ratchet wheel rotates the subrocket when the sliding member 74 is pushed into the case 73 and the pin 76 protruding from the ratchet wheel passes through the inclined part 78 of the slit 77. This action causes the screw holding belt to rotate. - Only the thread section is transported.

とによるものである。This means that the lower part of the head of the screw transferred under the driver bit before driving is held by the screw holding belt, and if the screw is long, the tip of the screw is attached to the screw holding belt. This is because the screw is often deviated from the driving direction, and if the screw length is long, it is difficult to continue driving the screw while keeping it straight in the driving direction after it engages with the driver bit and separates from the screw holding belt. .

。From the standby state, the tip of the sliding member 5 is brought into contact with the driven member 29, which is the other member into which the screw is driven, and the sliding member 5 is operated so as to be pushed into the case 3 against the return spring 4. Then, the bottle 2 is guided by the tapered part 28.
l slips under the lever 23. As the bin 21 is pushed downward by the lever 23, the ratchet wheel 18 engages with the sprocket l5, and while the bin 2l passes through the inclined portion 22A, the sprocket l5 moves the screw holding belt 14 by one screw distance. Rotates in eight directions. After passing through the inclined portion 22A, the pin 2l comes out from below the lever 23, and the ratchet wheel 18 separates from the sprocket 15. In this state, the sliding member 5
When pushed in further, the tip of the driver bit 30 that passes through the insertion hole 3l of the sliding member 5 engages with the head of the screw 13.
The screw l3 can be driven into the driven member 29 by the driver bit 30 which is rotationally driven by the electric driver tool 1. In the return operation, when the sliding member 5 retreats within the case 3 due to the biasing force of the return spring 4, the pin 21 moves downward along the slit 22 and returns to the standby state through the inclined portion 22A. During this return while passing through the slope part 22A,
Since the bin 21 rotates in the opposite direction through the elongated hole 20 while the ratchet wheel 18 is detached from the subrocket l5, only the ratchet wheel l8 simply rotates in the direction of arrow B.

うになっている。In this embodiment, the screw holding mechanism section 58 is designed so that the screw holding mechanism described above can be easily replaced when the screw holding mechanism breaks down.
Including the front leg part 32A, the protruding part 43, and the rear leg part 32B.
.. This is a block of part of 32C. This block 55 can be attached and detached by engaging and disengaging the plurality of upper and lower engaging portions 56 with the engaging portions 57 on the main body of the device, so that the block 55 can be easily replaced in the event of a failure. It is now possible to do this. Next, still another embodiment will be explained based on FIG. First, the general configuration of the screw driving device of this embodiment will be explained. The left and right side plates of the sliding guide case 59 attached to the ends of the connecting member 2 are provided with long holes 60 for sliding guides, as shown by cutting out the side cover 59A. A sliding member 62 having a pin 61 protruding left and right using a sliding guide that fits into the case 59 can slide within the case 59 within the elongated hole 80 against a return spring (not shown).

ねじ保持部材44は図示を省略した。The rotating lever 66 rotates the ratchet wheel 64 clockwise when the sliding member 62 is pushed into the case 59 and the bin 67 passes through the inclined rotation guide groove 68. The screw retaining belt l4 is transported by the -thread section by the meshing subrocket 63,
The screw l3 is attached to the front and rear legs 32A, 3 at the tip of the sliding member 62.
Sent between 2B. When the sliding member 62 is pushed back inside the case 59 by the return spring and returns to the standby state, when the pin 67 passes through the rotation guide groove 68, the ratchet wheel B4 rotates counterclockwise. As a result, the mesh with the subrocket 63 becomes disengaged, and the subrocket 63 does not rotate. After the hook lever 70 transfers the screw l3 under the driver bit, it moves the sliding restriction bottle 61 to the hook 70A.
This is to temporarily hold the sliding member 62 while it is being pushed into the case, and to easily center the screw marked on the member to be driven with the driving center. It is now possible to do this. The leg portions 32A, 32B, 32C and the protruding portion 43 of the sliding material 62 are provided with screw holding members 36, 44, and an operating lever 42. The screw holding mechanism 58 described above, which is composed of small protrusions 50 and the like, is provided. In addition, the leg portion 32C,
The screw holding member 44 is omitted from illustration.
以上説明したように本発明によれば、ドラバビット下に
移送されたねじをねじ保持部材によって打ち込み方向に
真っすぐ保持することができるので、5cm程度と長い
ねじを打ち込む場合でも、被打ち込み部材の打ち込み中
心に正確にねじを打ち込むことができる。As explained above, according to the present invention, the screw transferred under the driver bit can be held straight in the driving direction by the screw holding member, so even when driving a long screw of about 5 cm, the driving center of the driven member can drive screws accurately.
また従来は、ねじが打ち込み方向からずれている場合に
