The arrangement of the easy-cut holes 4 facilitates the processing of the slide groove 3 when the clearance holes 5 need to be opened during the installation of the power distribution device.

[0031] The housing 2 is fixedly provided with a sliding part 6, a placement hole 7 is provided on the sliding part 6, a steel ball 8 is placed in the placement hole 7, a spring 9 is placed in the placement hole 7, and the spring 9 is located between the steel ball 8 and the housing 2; the sliding part 6 is slidably provided in the slide groove 3, a limiting groove 10 is provided on the slide groove 3, and the steel ball 8 is pressed against the limiting groove 10; the slide groove 3 is provided with two paths; the guide rail 1 is fixedly provided with a limiting block 11, and four limiting blocks 11 are provided, and the four limiting blocks 11 are respectively provided at both ends of the two slide grooves 3. By installing the sliding part 6 in the slide groove 3 and making the steel ball 8 press against the limiting groove 10, the housing 2 can be conveniently adjusted on the slide groove 3 and fixed on the slide groove 3.

[0032] The housing 2 is provided with a mounting hole 12, in which a contact piece 13 is fixedly arranged. The housing 2 is provided with a tightening mechanism 14 which is rotatably arranged. The tightening mechanism 14 comprises a rotating part 15, a tightening part 16 and a toggle part 17. The rotating part 15 is rotatably arranged on the housing 2, the tightening part 16 is fixedly arranged on a side of the rotating part 15 close to the contact piece 13, and the toggle part 17 is fixedly arranged on a side of the rotating part 15 away from the tightening part 16; an isolating part 18 is fixedly arranged on the rotating part 15.
