Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1, it is the structural schematic diagram of the embodiment of the pay-off rack of the present invention. The pay-off stand comprises a support 1, wherein two ends of the support 1 are respectively provided with a coaxial fixed shaft section 2, a pay-off sleeve 3 is arranged between the two fixed shaft sections 2, and two ends of the pay-off sleeve 3 are respectively sleeved on the two fixed shaft sections 2 in a rotating fit manner; the difference between the distance between the two ends of the bracket 1 and the length of the pay-off sleeve 3 is more than or equal to the length of one of the fixed shaft sections 2; of course, the length of the pay-off sleeve 3 should also be greater than the distance between the two fixed shaft sections 2, which will not be described again. The two fixed shaft sections 2 of this embodiment are equal in length, facilitating the installation and the removal of the pay-off sleeve 3. The paying-off sleeve 3 is sleeved with at least one wire spool 4 which rotates synchronously with the paying-off sleeve, and the paying-off sleeve 3 is further provided with a hoop 5 for axially positioning the position of the wire spool 4.
