Claims

[Claims for Utility Model Registration] 1. A first fulcrum shaft 4 having a left-right direction is supported at the upper end of a column 3 erected near the front end of the base plate 2; A connecting rod 5 is arranged in a row so as to be able to rise and fall freely, a ratchet 6 is fixed to the lower end of the connecting rod 5, and a ratchet 6 is attached to the upper end of the connecting rod 5 and acts in the front-rear direction via a second fulcrum shaft 7 having a left-right direction. A third fulcrum shaft 9 is provided at a position near the first fulcrum shaft 4 behind the strut 3 on the base plate 2, and a third fulcrum shaft 9 is connected to the strut 3 and the ratchet. A lever characterized in that a claw 10 that engages and disengages from a lever 6 is provided in a manner that can be raised and lowered freely. 2 The base frame 21 corresponding to the substrate 2 has a rod attachment part 21A having an inverted U-shaped cross section due to the shape of the rod 13 to be processed, and an upright plate fixed to the rear end of this attachment part. 21B, and left and right cylindrical anchor receivers 21C attached vertically to the left and right corners of this upright plate, and the point of action formed at the tip of the lever corresponds to the shape of the rod 13 to be processed. The lever according to claim 1, wherein the lever has a claw shape with an inverted U-shaped cross section.
