Field of the Invention The present invention relates to a suspension clamp for supporting an electric wire, which is easy to attach and detach and which does not damage the electric wire when the electric wire is mounted. is there. 2. Description of the Related Art The following structure of a suspension clamp is known from Japanese Utility Model Publication No. 3-4119. In order to protect the electric wire, the electric wire is held by a pair of upper and lower soft resin collars, supported by a hook of the main body, and a through bolt is attached to the main body so as to be able to be tightened by a holding metal pivotally attached to the main body. In this case, the lower hook, the electric wire, and the upper collar are stacked in three stages on the main body hook, the hanging holder is lifted, and most of the processes of inserting the through bolts require simultaneous operation of both hands. It was not appropriate as the above work. Also, when tightening the pair of upper and lower collars, there was a risk that the wires would be bitten at both ends. A cylindrical member having eccentric large-diameter flanges at both ends is provided with a notch on an eccentric side, and a resin material (hereinafter, referred to as a "protective cover") provided with outward opening elasticity is prepared. The protective cover is mounted between the main body and the holding metal with the cut side up. The presser bracket is pivotally attached to the main body at the lower end, and has a gap at an upper portion where an electric wire can be inserted, and prevents a downward rotation. Insert the electric wire from above and tighten the main body and the holding bracket with the through bolt. Since the wires are supported at the lower part of the closed space, there is no risk of damage at the upper edge. The penetrating bolt has a rectangular head, and the bolt hole of the main body has a rectangular shape that allows passage of the bolt easily. When the penetrating bolt is turned after insertion, it is locked at the rectangular hole of the main body. To prevent the bolts from rotating together when tightening the nut, a square portion is provided adjacent to the rectangular head. The penetrating bolt is integrated into the holding bracket together with the nut and can be operated as it is, so that it can be operated with one hand without fear of dropping parts. Also, since the head of the penetrating bolt is spherical, the electric wire is not damaged by the bolt head when inserted between the main body and the press fitting. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 7, for example, as shown in FIG.
And a protective cover, and a main body, a holding bracket,
Consists of four parts of through bolts. As shown in FIGS. 4 and 5, the protective cover 1 is provided with large-diameter flanges 1b which are eccentric at both ends of the cylindrical portion 1a.
A cut is made on the eccentric side, and projections 1c are provided on the inner surface of the flange on the left and right. Since it is made of a soft resin and provided with open-open elasticity, unlike the case of a single unit, the cut is opened by a predetermined angle. As shown in FIG. 1, the main body 2 has a retaining portion at the upper end, a semicircular portion corresponding to the cylindrical portion of the protective cover at the center, and a pin 3 at the lower end. The central portion has a width that can be gripped by both flanges of the protective cover, and has a hole corresponding to the projection 1c of the protective cover. When both are engaged, the protective cover is positioned and locked with the cuts vertical. Although the lower end of the presser fitting 4 is pivotally attached to the main body by the pin 3, the lower end tail portion 4a is in contact with the rear surface of the main body, so that the rotation range is limited, and the lower end does not hang down. The central part is opposed to the main body and holds the cylindrical part,
And is positioned and locked by the engagement between the projection 1c and the hole. Further, the upper end portion is brought into contact with the main body so that the through bolt 5 can be inserted therethrough. The penetrating bolt 5 has a spherical rectangular head 5 as shown in FIG.
a, a square portion 5b, and a screw portion 5c, and the bolt hole of the main body is also rectangular corresponding to the head. FIG. 1 shows that the presser fitting is moved to the left so that the head of the penetrating bolt passes through the rectangular hole 2a of the main body to expose a square portion, and then the head is turned 90 degrees to the right to return the head to the main body. Shows where it is locked. At this time, since the square portion 5b is engaged with the rectangular hole 2a of the main body, when the nut 6 is tightened, the bolt does not twist. [0005] It is assumed that the penetrating bolt is detached from the main body, the holding metal is stopped by the stopper action of the tail part 4a, and the upper part of the clamp is closed by this suspended clamp. After inserting the electric wire into this, the presser fitting is returned, and the through bolt is tightened as described above. There is no need to use both hands in the electric wire mounting process described above. You can grab the ladder with one hand and do all the work with the other. Further, since the cut of the protective cover is at the upper side, there is no danger of damaging the wire coating supported on the lower surface.
