Abstract
The utility model relates to a pneumatic type hand clamping tool. The tool comprises a stent, a transmission shaft which is axially and actively connected on the stent, a left and a right connecting rods which are actively connected to the ends of the transmission shaft, a left and a right crab clamps which are actively connected with the left and right connecting rods together respectively, an upper and a lower support plates which are fixedly connected on the stent. The left and the right crab clamps are actively connected on the upper and the lower support plates correspondingly. The special departments of the utility model are that the upper ends of the left and the right crab clamps are provided with corresponding scissors, and the left and the right crab clamps which are under the scissors are provided with corresponding internal semicircle edges respectively, the upper and the lower support plates which are under the internal semicircle edges are provided with positioning ports. Compared with the prior technology, the utility model has the advantage that the misoperation of shearing break the article which is ought to be reduced in diameter can not occur easily.
Description
Technical field:
The utility model relates to a kind of small tool.
Background technology:
The portable clamp instrument of existing pneumatic type mainly by support, axially be actively socketed on power transmission shaft on the support, be actively socketed on the left and right sides connecting rod of transmission axle head, the left and right sides crab claw that are movably connected with left and right sides connecting rod respectively, the upper and lower support plate that is fixed on the support and constitute, the left and right sides crab claw relatively are actively socketed on the upper and lower support plate, be provided with the interior semicircle edge of a knife of symmetry in the upper end of the left and right sides crab claw, be respectively equipped with corresponding scissors on the left and right sides crab claw below the interior semicircle edge of a knife.During work, cylinder drives power transmission shaft and does axially-movable, and power transmission shaft drives left and right sides connecting rod swing, and left and right sides connecting rod drives the left and right sides crab claw and does open and close movement, thereby tightens up or object is cut off by the interior semicircle edge of a knife on the crab claw or the scissors somewhere diameter with object.The portable clamp instrument of this kind pneumatic type since scissors be positioned at the semicircle edge of a knife below, and it is very heavy often to tighten up the article of diameter, like this, on the scissors in article just drop into easily below the semicircle edge of a knife, generation maloperation and being cut off by scissors.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of portable clamp instrument of pneumatic type that article are cut off in maloperation that can not produce.
The utility model is to realize like this, comprise support, axially be actively socketed on power transmission shaft on the support, be actively socketed on the left and right sides connecting rod of transmission axle head, the left and right sides crab claw that are movably connected with left and right sides connecting rod respectively, be fixed in the upper and lower support plate on the support, the left and right sides crab claw relatively are actively socketed on the upper and lower support plate, its special feature is to be provided with in the upper end of the left and right sides crab claw scissors of correspondence, be respectively equipped with the corresponding interior semicircle edge of a knife on the left and right sides crab claw below scissors, be provided with locating aperture on the upper and lower support plate below the interior semicircle edge of a knife.
During use, when needs are received object certain diameter little, earlier object is placed in the crab claw of the left and right sides, object is leaned against on the locating aperture of upper and lower support plate, start cylinder then, drive left and right sides crab claw closure by power transmission shaft, left and right sides connecting rod, by the interior semicircle edge of a knife on the crab claw that the diameter receipts of semicircle knife-edge part in placing on the object are little, so that with the thing in the object (as placing the interior steel wire rope of pipe) banding.In the time of need cutting off ropy (as steel wire rope),, start cylinder, drive left and right sides crab claw closure, ropy is cut off by the scissors on the crab claw by power transmission shaft, left and right sides connecting rod as long as ropy is placed on the scissors.
The utility model is owing to place the interior semicircle edge of a knife on the scissors of the crab claw, thereby lowered greatly that the object misplace that will need to receive minor diameter cut off on scissors may, because this object has constant weight often, utilize its deadweight to drop on the locating aperture on the upper and lower support plate, the possibility that it is dropped on the scissors is very low.Therefore, compared with the prior art the utility model has and is not easy to produce the advantage that these article that will receive minor diameter are cut off in maloperation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in the figure, the utility model, mainly by support 1, axially be actively socketed on the power transmission shaft 2 on the support 1, be actively socketed on the left and right sides connecting rod 3 of power transmission shaft 2 ends, 4, respectively with left and right sides connecting rod 3,4 left and right sides crab claw 5 that are movably connected, 6, be fixed in the upper and lower support plate 7 on the support 1,7a constitutes, the left and right sides crab claw 5,6 relatively are actively socketed on upper and lower support plate 7, on the 7a, its special feature is at the left and right sides crab claw 5,6 upper end is provided with corresponding scissors 8,9, at scissors 8, the left and right sides crab claw 5 below 9, be respectively equipped with the corresponding interior semicircle edge of a knife 10 on 6,11, at the interior semicircle edge of a knife 10, upper and lower support plate 7 below 11,7a is provided with locating aperture 12.End 13 and 1 on support at power transmission shaft 2 are provided with returning spring 14, are returned to original position so that the left and right sides crab claw 5,6 engage object receipts footpath or object is cut off the back under the effect that recovers spring 14.
