Description

Technical Field

[0001] The utility model relates to the technical field of wire construction cutting, in particular to a cutting device for the construction of the power supply wire of a lighting fixture. Background Art

[0002] The cutting device for the power supply wire of a lighting fixture is mainly used for cutting wires or cables in a power supply line during the construction of a lighting system, so as to carry out wiring, install lighting fixtures or perform other necessary electrical connection work.

[0003] In the prior art, the patent document with the publication number of CN212968818U discloses a cable truncation device for electric power construction, including a wire transmission box. Compared with the existing ordinary cable truncation device, this device adjusts the elongation of the scale telescopic rod, and then the motor drives the first transmission roller to rotate and cooperate with the second transmission roller to transmit the cable. When the cable contacts one end of the scale telescopic rod, the hydraulic cylinder cooperates with the cutter to perform equal-length truncation on the cable; by rotating the threaded rod to drive the C-shaped rod to move up and down and drive the first transmission roller to move up and down, the distance between the first transmission roller and the second transmission roller is adjusted, so as to facilitate the clamping and transmission of cables with different diameters by the first transmission roller and the second transmission roller; through the cooperation of the support plate and the collection box, it is convenient to collect the cut cables, reducing the burden on the user and facilitating the user to carry the cut cables, saving time and effort.

[0004] During the use process, it is found that the above device is relatively large in size. When truncating the cable on a support surface, if it is found that the length of the cable fixed at one end is relatively long during the construction process, other tools are still needed for truncation, and the use has certain limitations.
