Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] The invention adopts a simplified pulley block (threading hole) to increase the force, and improves the shearing force of the traditional steel bar shears. Such as figure 1 As shown in the figure, a simple pulley-type reinforced steel bar shear includes a pair of knife scissors 1, a frame 2, a limit frame 7, a limit plate 8, a take-up handle 4, a take-up handle installation shaft 9, two nylon ropes Frame 3, nylon rope 5, force pin 13.

[0015] Such as figure 2 As shown, the two blades of the pairing scissors 1 are hingedly fixed to one end of the frame 2, the limit plate 8 is installed on the other end of the frame 2, the take-up handle installation shaft 9 is installed on the limit plate 8, and the take-up The handle 4 is hinged on the take-up handle installation shaft 9; the limit frame 7 is installed on the frame 2 for installing the nylon rope frame 3; the tw...

Abstract

The invention discloses a pair of simple pulley reinforcing steel bar scissors. A force increasing mechanism is added for a pair of ordinary knife type steel bar scissors by adopting a simplified pulley block, and the shearing force of a pair of traditional manual knife type steel bar scissors is increased. The pair of simple pulley force-increasing steel bar scissors has the advantages of simple structure, convenience in use, low cost and no use of any energy source and can be widely applied to shearing metal wires.

Description

technical field [0001] The invention relates to a steel bar shearing tool, in particular to a simple pulley type reinforced steel bar shear. Background technique [0002] In construction, machinery, and rescue industries, steel bar cutting tools are widely used to cut metal wires such as steel bars and cables. Presently known steel bar shearing tool has following several: (1) manual steel bar is cut, is common pair of knife type scissors usually. This kind of scissors utilizes a simple lever principle to increase force, and the shearing force is small, but the volume is large; it is not suitable for people with weak physical strength. (2) Manual hydraulic steel bar shears. Compared with ordinary paired scissors, this kind of scissors has the advantage of large shear force, but the structure is complicated, and the hydraulic oil is easy to leak, the maintenance is inconvenient, and the cost is also high. (3) The steel bar shearing machine uses additional energy such as elec...
