DETAILED DESCRIPTION
[0012] For example, see the attached Figures 1 to 4The adjustment limit locking carbon brush holder is to fix the square baffle plate 4 on the boss 7-2 above the brush holder body 7 with screws, and the circular hole on the baffle plate 4 is provided with an adjustment plate seat 4-1, and the adjustment plate seat 4-1 is provided with an adjustment plate slot, and the shaft 3 in the adjustment plate slot is fixedly connected with the adjustment plate 6 of right angle sectors with different radii, and the adjustment rod sliding slot 6-1 with the same angle and arc shape as the adjustment plate 6 is provided at the outer arc edge of the adjustment plate 6. The adjustment rod 5 with an upper circle and a lower part is slidingly matched in the adjustment rod sliding slot 6-1, and the upper end of the adjustment rod 5 is 7-8mm higher than the adjustment plate 6, and the square section of the adjustment rod 5 corresponds to the adjustment rod slot 7-1 in the middle of the front of the brush holder body 7. The lower end of the adjustment rod 5 is fixed in the middle of the outer side of the brush pressing plate 14. The brush box 8 is fixed with a fastening bolt 19 in front of the brush holder body 7. Four constant pressure spring slots 8-1 are provided at the front and bottom of the brush box 8. The constant pressure spring coil 10 is installed in the constant pressure spring slot 8-1. The upper end of the constant pressure spring coil 10 is fixed to the top of the brush box 8 with a constant pressure spring fixing bolt 9. The brush pressing plate 14 is fixedly connected to one end of the spring seat 13 below the four constant pressure spring slots 8-1 below the brush box 8.
