Utility model content
The purpose of this utility model is to provide a kind of fastener, and to solve existing fastener in use, movable chuck easily slides, the problem that fastening effect is lower.
The utility model provides a kind of fastener, comprise the kelly that is provided with the body of rod and hook portion, one end of the described body of rod connects described hook portion, described fastener also comprises and the movable movable chuck coordinating of the described body of rod, the described body of rod is provided with plural through hole, and described through hole longitudinally arranges on the described body of rod.The body of rod and the hook portion of kelly are generally Integral design, to meet higher requirement of strength, after movable chuck and kelly clamping template, by fixtures such as iron wire or nails, penetrate the through hole of diverse location on the body of rod, movable chuck in diverse location when being fixed on the template of fastening different-thickness, prevents in use, due to the effect of external force, movable chuck is slided to the one end away from institute's clamping plate, and then guaranteed the fastening effect of fastener.
Further, described through hole is that diameter is the circular port of 0.5cm.So neither affect the intensity of kelly, can realize again fixtures such as penetrating iron wire or nail.
Further, the spacing between described through hole is 1cm.Through hole distributes relatively uniformly and can avoid stress to concentrate, thereby has guaranteed the intensity of kelly, and the spacing of 1cm be can meet preferably fastening different-thickness template time, the different permanent positions of movable chuck.
Further, the described through hole of the A end face of close described kelly and the distance between described A end face are not less than 10cm, the described through hole of B end face and the distance of described B end face near described kelly are not less than 10cm, the end face away from described hook portion that described A end face is described kelly, described B end face that be the described body of rod with end face described hook portion junction.The scope of application of fastener has been covered in the distribution of through hole like this, has guaranteed again the intensity of kelly simultaneously.
Further, described through hole is positioned at the centre position transversely of the described body of rod.In centre, be provided with and be beneficial to the intensity that guarantees kelly, not fragile, longer service life.
The beneficial effects of the utility model are, on the body of rod by the kelly at fastener, offer plural through hole, and through hole is along longitudinal setting of the body of rod, the hook portion of movable chuck and kelly is clamped after template, by objects such as iron wire or nails, penetrate the through hole of diverse location on the body of rod, movable chuck in diverse location when being fixed on the template of fastening different-thickness, prevent in use, effect due to external force, movable chuck is slided to the one end away from institute's clamping plate, and then guaranteed the fastening effect of fastener.
Accompanying drawing explanation
Fig. 1 shows the schematic diagram of the fastener that the utility model the first embodiment provides;
Fig. 2 shows the schematic diagram of the fastener that the utility model the second embodiment provides.
The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
Fig. 1 shows the fastener that the utility model the first embodiment provides, comprise the kelly that is provided with the body of rod 1 and hook portion 2, one end of the body of rod 1 connects hook portion 2, this fastener also comprises and the movable movable chuck 3 coordinating of the body of rod 1, the body of rod 1 is provided with plural through hole 4, and through hole 4 longitudinally arranges on the body of rod 1.The body of rod 1 is with hook portion 2 for integral type designs, and the length of kelly is 80cm, and through hole 4 is that diameter is the circular port of 0.5cm, and through hole 4 is non-equidistance setting.Through hole 4 and the distance between A end face 5 near the A end face 5 of kelly are 20cm, near the through hole 4 of the B end face 6 of kelly and the distance of B end face 6, are 20cm, the end face away from hook portion 2 that A end face 5 is kelly, and B end face 6 is the body of rod 1 and end faces hook portion 2 junctions.
In the present embodiment, while using this fastener, make the hook portion 2 of kelly hook template, then by movable chuck 3, hook portion 2 ends to kelly move, until clamping template, then penetrate the through hole 4 nearest apart from movable chuck 3 with nail or iron wire, thereby further fixing movable chuck 3, while preventing from being subject to external force or vibration, movable chuck 3 slides to the direction away from template, and then has guaranteed the fastening effect of fastener.
Fig. 2 shows the fastener that the utility model the second embodiment provides, comprise the kelly that is provided with the body of rod 1 and hook portion 2, one end of the body of rod 1 connects hook portion 2, this fastener also comprises and the movable movable chuck 3 coordinating of the body of rod 1, the body of rod 1 is provided with plural through hole 4, and through hole 4 longitudinally arranges on the body of rod 1.
The body of rod 1 is with hook portion 2 for integral type designs, and the length of kelly is 70cm, and through hole 4 is that diameter is the circular port of 0.5cm, neither affects the intensity of kelly, can realize again fixtures such as penetrating iron wire or nail.And the spacing between through hole 4 is 1cm, through hole 4 distribution relatively uniformly can avoid stress to concentrate, thereby has guaranteed the intensity of kelly, and the spacing of 1cm be can meet preferably fastening different-thickness template time, the different permanent positions of movable chuck 3.Through hole 4 is positioned at the centre position transversely of the body of rod 1, is conducive to guarantee the intensity of kelly, not fragile, longer service life.Through hole 4 and the distance between A end face 5 of the A end face 5 of close kelly are 10cm, the through hole 4 of the B end face 6 of close kelly is 10cm with the distance of B end face 6, the end face away from hook portion 2 that A end face 5 is kelly, B end face 6 is the body of rod 1 and end faces hook portion 2 junctions, the scope of application of fastener has been covered in the distribution of through hole 4 like this, has guaranteed again the intensity of kelly simultaneously.
In the present embodiment, while using this fastener, make the hook portion 2 of kelly hook flitch, then by movable chuck 3, hook portion 2 ends to kelly move, until clamping template, then penetrate the through hole 4 nearest apart from movable chuck 3 with nail or iron wire, thereby further fixing movable chuck 3, while preventing from being subject to external force or vibration, movable chuck 3 slides to the direction away from template, and then has guaranteed the fastening effect of fastener.
