Supports 3 for inserting the screw nails A into the base 2 are provided at regular intervals in the longitudinal direction, and the support 3 is provided on the belt-like base 2 with an inner diameter that is compatible with the shaft B of the screw A. A hole 4 and a cylindrical support tube 5 projecting around the insertion hole 4 on the back side of the band-shaped base 2, and a notch 6 for feeding is provided on both sides of the band-shaped base 2. It has a structure provided at the same pitch as that of FIG.
[0003]
In the illustrated case, the support tape 1 is provided with a plurality of slits 5a in the middle of the support tube 5 from the belt-like base 2 to improve the passage of the head C of the screw A.
[0004]
Such a support tape 1 is mounted on an electric screwdriver tool 7 as shown in FIGS. 10 to 12, and is used for continuous driving of the screw nail A.
[0005]
The electric screwdriver tool 7 has a sliding member 11 movably housed in a guide case 10 which is screwed and fixed to a tool body 8 with a connection screw tube 9, and is inserted into the sliding member 11 from the guide case 10. And a guide 24 that supports the support tape 1 and guides the guide to the sliding member 11 is attached to the outer surface of the guide case 10.
[0006]
The sliding member 11 is vertically guided by a long hole 13 provided in the guide case 10 and a pin 14 fixed to the sliding member 11 so as to fit in the long hole 13, and provided in the guide case 10. The sliding member 11 is always pressed to the lowered position by the coil spring 15, and a guide groove 16 for inserting the support tape 1 is provided in the sliding member 11 so as to penetrate the sliding member 11. At the upper position of the guide groove 16, there is provided a feed claw 17 for engaging the feed notch 6 on both sides of the support tape 1 in the guide groove 16. The contact fitting 18 is fixed to the casting surface.
[0007]
The feed claw 17 is a feed mechanism 21 including a bent groove 19 of the guide case 10 and a swing pin 20 attached to the slide member 11 so as to fit in the guide groove 10. Each time it moves up and down, it rotates intermittently at a predetermined angle to feed out the support tape 1 in the guide groove 16 by a pitch equal to the arrangement interval of the support portions 3. During the lowering, the screw engages with the driver engaging groove provided in the head C of the screw nail A held by the support portion 3 located in the guide groove 16 of the support tape 1, and the screw nail is attached to the screwed member. A will be screwed.
[0008]
When the screw A is screwed into the threaded member with respect to the support tape 1, the head C pushes the insertion hole 4 of the support portion 3 and the support cylinder 5 to pass through.
[0009]
FIG. 11 shows the relationship between the conventional support tape 1 and the guide groove 16 of the sliding member 11. In the guide groove 16, the cross-sectional shape of the band-shaped base 2 is sufficiently accommodated in order to ensure smooth movement of the support tape 1. The sliding member 11 is formed with a width and a height, and the sliding member 11 is provided with a head storage groove 22 for the screw nail A at an upper part of the guide groove 16 and a head passage groove 23 at the lower part. .
[0010]
[Problems to be solved by the invention]
As described above, since the guide groove 16 of the sliding member 11 is formed in a horizontally long shape having a width and a height in which the cross-sectional shape of the belt-shaped base 2 can be accommodated with a margin, the support tape 1 accommodated in the guide groove 16 is As shown in FIG. 11, an upper and lower gap a is generated between the guide tape 16 and the guide tape 16. Due to the existence of the gap a, the support tape 1 is particularly loose in the guide groove 16. Poor feed of the support tape 1 and fall of the screw nail A will occur.
[0011]
If the screw A falls down, the axis of the screwdriver A and the screw A will not be aligned, and if the screwing operation is performed in such a state, the wall material into which the screw A is screwed may be damaged or the screw A may be damaged. There is a problem that the screw nail A that bites into the inside of the sliding member 11 to interrupt the work and needs to be removed must be removed.
[0012]
As a method for solving such a problem, it is conceivable to increase the thickness of the support tape 1 to reduce the upper and lower gaps a between the support tape 1 and the guide groove 16. However, if the thickness of the support tape 1 is increased, The removal of the head C of the screw nail A from the support tape 1 becomes worse, and the workability decreases, which is not preferable.
[0013]
Therefore, an object of the present invention is to eliminate the occurrence of vertical rattling in the guide groove of the sliding member of the electric driver tool without increasing the thickness of the support tape, and to improve the mobility of the support tape and the removal of the head of the nail. An object of the present invention is to provide a support tape of a fixing tool which can prevent poor feeding of the support tape and occurrence of falling down of the nail while ensuring the property.
