Since the diameter of the fixing rod 2 is smaller than that of the connecting rod 1 and the connecting head 4, the connecting rod 1 and the connecting head 4 can limit the limiting sleeve 3 to prevent the limiting sleeve 3 from sliding.

[0023] A main fixing box 6 is installed on the limiting sleeve 3, an auxiliary fixing box 7 is installed on the main fixing box 6, a communicating pipe 8 is connected to the main fixing box 6, a connecting plate 9 is connected to the main fixing box 6, grooves 18 are provided above and below the connecting plate 9, springs 19 are connected in the grooves 18, one end of each spring 19 is connected to a clamping block 20, and inclined surfaces are provided on both sides of the clamping block 20. Through the inclined surfaces on both sides of the clamping block 20, the slot wall of the slot 11 can flexibly push the clamping block 20 to move, so as to facilitate the staff to install and disassemble the main fixing box 6 and the auxiliary fixing box 7.

[0024] On one side of the main fixing box 6 opposite to the auxiliary fixing box 7, an arc-shaped groove 10 is provided. A slot 11 is formed in the auxiliary fixing box 7, and a jack 12 is formed in the auxiliary fixing box 7. A micro pump 13 is installed on one side of the auxiliary fixing box 7 through a pipeline. The arc-shaped grooves 10 on the main fixing box 6 and the auxiliary fixing box 7 together form a circular hole and are in fitting contact with the limit sleeve 3. One side of the micro pump 13 is connected with an infusion tube 14, and during actual operation, the infusion tube 14 will be connected to the box body storing cutting fluid on the processing machine tool, so as to prevent the main fixing box 6 and the auxiliary fixing box 7 from rotating with the tool body 5 by the rotation of the acting force and the limit sleeve 3 on the fixing rod 2.

[0025] Liquid storage cavities 15 are provided inside both the auxiliary fixing box 7 and the main fixing box 6.

As the connecting plate 9 is inserted, the clamping block 20 will be pushed into the groove 18 by the slot wall of the slot 11 to compress the spring 19, and then the spring 19 will rebound to push the clamping block 20 into the card slot 21 to fix the connecting plate 9, preventing the main fixing box 6 and the auxiliary fixing box 7 from being accidentally separated. During operation, the micro pump 13 will transport the cutting fluid to the liquid storage cavity 15 in the auxiliary fixing box 7 through the infusion tube 14, and the communicating pipe 8 will ensure the circulation of the cutting fluid in the main fixing box 6 and the auxiliary fixing box 7, prompting the spray heads 17 below the main fixing box 6 and the auxiliary fixing box 7 to work together to cool and lubricate the tool body 5 performing the cutting work.
