Description
Technical Field
The invention relates to the technical field of pipe cutting tools, in particular to a tubular material cutter with an easily replaceable blade.
Background
The existing pincer type PVC pipe cutter mainly comprises a large handle, a small handle, a push pawl, a pull pawl, a tail buckle, a plurality of springs, a blade, a ratchet and the like. The principle of the novel broach is that an operator overcomes the resistance of a torsional spring for pulling the ratchet, pulls the button spring to rotate towards the outer side far away from the ratchet piece, continues to overcome the resistance of the torsional spring on the pushing ratchet, drives the pushing ratchet to rotate towards the outer side together, enables the pushing ratchet and the pulling ratchet to be separated from the ratchet of the ratchet piece, and enables the blade to be quickly retracted under the action of the button spring, so that the next-time broach feeding is prepared. Because the resistance of a button spring on the ratchet is required to be pushed and pulled at the same time when the cutter is withdrawn, the defects of labor waste when the cutter is withdrawn and slow conversion speed of the cutter withdrawing and withdrawing are overcome; in addition, the existing tubular material cutter needs to be integrally disassembled when the blade is replaced due to the complex structure, so that the blade is very inconvenient to disassemble and assemble.
In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, chinese patent literature discloses a portable quick automatic retracting pincer type PVC pipe cutter [ CN200720107773.5], which comprises a pincer type body composed of a small handle and a large handle, and a blade, a ratchet piece, a large screw, an adjusting block and a matching adjusting block compression spring which are assembled; the small handle and the large handle are connected through a pin column to realize movable connection; the blade and the ratchet piece are positioned through the positioning pin and the positioning hole of the blade and the ratchet piece, and are fixed into a component by two blade screws; then the big screw is tightly pressed on the big handle and can rotate; the regulating block is connected to the large handle through a spring pin and is compressed by a regulating block pressure spring. When the pushing pawl pushes the ratchet piece, the blade makes a circular feed motion along with the pushing pawl to realize the action of cutting the pipe, and when the pushing pawl pushes the ratchet piece to move forward by one step, the pulling pawl hooks the ratchet piece to prevent the blade from moving backward; when the knife is retracted, the plastic tail buckle is rotated to the large handle.
