Simple fixing device for cable trench support

The invention discloses a simple fixing device for a cable trench bracket. The simple fixing device for the cable trench bracket comprises a base, a main body and at least two clamping structures, wherein the lower end of the main body is fixedly connected with the base, the upper end of the main body extends upwards, and scale marks marked in the vertical direction are arranged between the upper end and the lower end of the main body; one end of each clamping structure is connected with the main body and can be adjusted relative to the main body in the vertical direction, the other end of each clamping structure extends in the direction away from the main body in the horizontal direction, and each clamping structure is used for fixing and clamping a cable. According to the arrangement, the distance between the cable trench supports can be measured through the scale marks on the main body, so that the use of measuring tools is reduced, meanwhile, a plurality of cable trench supports can be installed through t
