Background

The wire clamping device is a stringing construction tool for an electric power department for paying off and tightening wires, and the wire clamping device for clamping the wires is used because the wires are drawn by the wire tightening device in the wire-tightening operation of the wire construction.

The existing wire clamping device comprises a connecting plate, a pull ring, an upper jaw, a lower jaw, a main plate, a pull arm, a pull ring, a spring support, a screw, a spring and the like as in Chinese patent with application number CN200920070588.2, wherein the main plate is connected with the lower jaw through three pin shafts; the pin shaft and the nut are tightly riveted and fixed by a riveting machine, so that the main board and the lower jaw cannot move. The connecting plate is connected with the lower jaw through a pin shaft, and the pin shaft and the nut are tightly riveted and fixed through a riveting machine, but the free movement of the pin shaft and the nut is ensured. The pull arm and the connecting plate are connected by a pin shaft, and the pin shaft and the nut are tightly riveted and fixed by a riveting machine, but the free movement of the pin shaft and the nut is ensured. A spring is arranged between a spring bracket and the pull arm on the connecting plate to ensure that the wire clamping device can automatically reset. The pull arm, the main board and the pull ring are connected through a pin shaft, and the pin shaft and the nut are tightly riveted and fixed through a riveting machine, but the free movement of the pin shaft and the nut is ensured.

The above prior art solutions have the following drawbacks: the model of cable, the electric wire that this kind of fixing-line device that has now can the centre gripping is all at certain extent value, for example the fixing-line device of centre gripping cable can't be used for the thin iron wire of centre gripping, and the fixing-line device of the thin iron wire of centre gripping also can't interlock the great cable of diameter naturally, consequently often need carry the fixing-line device of different accommodation in electrician's operation process, and is comparatively loaded down with trivial details and operation flexibility relatively poor, consequently, has the space of improving.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a be used for cable laying to use fixing-line device has the function that can dismantle the anchor clamps of changing the difference at punch holder and lower plate to a size that is used for adapting to different cable or electric wire.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

a wire clamping device for cable laying comprises a wire clamping device body, wherein the wire clamping device body comprises an upper clamping plate, a lower clamping plate, a main plate and a pull ring, a first clamping groove and a second clamping groove are formed in clamping openings of the upper clamping plate and the lower clamping plate, which face each other, respectively, the first clamping groove and the second clamping groove extend along the length direction of the upper clamping plate and the lower clamping plate, one ends of the first clamping groove and the second clamping groove, which are far away from the pull ring, are blocked, and an opening is formed in the other ends of the first clamping groove and the second clamping groove; first anchor clamps and second anchor clamps are slided to the joint respectively in first draw-in groove and the second draw-in groove, first draw-in groove and second draw-in groove are close to the one end of pull ring all is provided with the shutoff open-ended limit structure.

Through adopting above-mentioned technical scheme, set up the first draw-in groove sliding connection who has first anchor clamps at the punch holder, set up the second draw-in groove sliding connection who has the second anchor clamps at the lower plate to can realize the regulation to pressing from both sides the mouth between punch holder and the lower plate through prefabricating and changing not unidimensional first anchor clamps and second anchor clamps, can adapt to major diameter's cable or minor diameter's steel wire etc.. Thereby first anchor clamps and second anchor clamps can not break away from in first draw-in groove or the second draw-in groove by the spacing restriction of shutoff end when taut cable by the one end shutoff setting that first draw-in groove and second draw-in groove kept away from the pull ring, then shift out first anchor clamps and second anchor clamps and change from the open end of first draw-in groove and second draw-in groove when needing to be changed first anchor clamps and second anchor clamps. Wherein limit structure is used for spacing first anchor clamps and second anchor clamps in daily use, avoids first anchor clamps and second anchor clamps to drop from first draw-in groove or second draw-in groove in the unconscious.
