a copper rod

Abstract

The invention belongs to the technical field of copper rods, specifically a copper rod, including a copper cover, an anti-slip pattern, a copper round rod, a finger pressure plate, a round copper plate, a round copper block, a cross-head bolt, a square through hole, a return spring, Square mouth slot, rectangular guide block, movable pin, first torsion spring, column slot, threaded hole, second torsion spring, shaft rod and single-slot copper wheel. The design of the invention is reasonable, and it is beneficial to fix and connect the glass cutter heads with connection structures of different specifications and sizes by adjusting the distance between the three cross-head bolts, so as to realize the function of reciprocating knocking on the structure of the cut plate with the glass cutter head , and it is convenient to knock off the exhaust gas plate structure on the scratched side, by pulling out the ink-soaked thin wire wound on the single-groove copper wheel from the copper cover, fix the two ends of the thin wire in a straight line close to the corresponding structure surface and Loosen upwards to spring the thread, thus having the auxiliary function of drawing a straight line on the surface of the corresponding structure.

Description

technical field [0001] The invention belongs to the technical field of copper rods, in particular to a copper rod. Background technique [0002] A glass knife refers to a tool used to cut glass. Usually, the part of a glass knife used for cutting is made of diamond or alloy material that is harder than glass. This part is at the tip of the knife. The knife can be divided into diamond glass knife and alloy roller glass knife. It is suitable for cutting flat glass with a thickness of 1-8 mm. It is an indispensable glass cutting tool for decoration and building materials industries. [0003] When using a copper rod connected by a glass knife, when hitting the surface of the structure to be cut, it is necessary to continuously raise the hand to drive the whole reciprocating movement to knock. The operation wrist is sore, and the glass cannot be cut ideally. At the same time, the glass cutter head will fall during use after the copper rod is used to fix the glass cutter head, wh...

[0003] When using a copper rod connected by a glass knife, when hitting the surface of the structure to be cut, it is necessary to continuously raise the hand to drive the whole reciprocating movement to knock. The operation wrist is sore, and the glass cannot be cut ideally. At the same time, the glass cutter head will fall during use after the copper rod is used to fix the glass cutter head, which will damage the nearby objects, and is not conducive to the glass cutter head. protection of
