Description

Technical Field

[0001] The utility model relates to the technical field of copper wire stretching, in particular to a multifunctional copper wire stretching device. Background Art

[0002] The copper wire stretching machine is also known as the copper core wire tensile machine. Its basic functions are tensile performance, tensile strength and deformation rate, breaking force, tear resistance, heat sealing strength performance, and roller peeling test. Most of the copper wire stretching devices currently used cannot prevent the copper wire from being broken and injuring people. During use, when the copper wire is stretched, the copper wire may be broken, causing the copper wire to bounce onto the person's body, causing certain injuries to the person. It has poor safety and practicality, and is not convenient for fixing the copper wire. During use, the copper wire needs to be fixed before work. Manual fixation may make the copper wire unstable, which may cause the copper wire to break free during stretching, reducing its clamping stability and poor practicality. Patent documents have now been used to improve this.

The utility model can prevent the copper wire from being broken and injuring people through the setting of the lifting mechanism. During use, the first motor rotates, thereby driving the first gear to rotate in the first gear slot, so that the first lifting rod rises or falls, allowing the test to be carried out in the box, thereby protecting the test personnel and preventing injuries to personnel due to the copper wire being broken, thereby improving its safety and making it more practical.

[0004] Although the above patent solves the problem that the copper wire may be broken when it is stretched, causing the copper wire to bounce onto a person and cause certain injuries to the person, the above patent requires the use of multiple motors to control the movement and the manual control of the lifting mechanism to control the movement of the copper wire on the workbench into the box for protection, which is too cumbersome to use.
