[0027] like Figure 1-4As shown, it includes a heat dissipation component and two telescopic rods 1. The telescopic rods 1 are of an adjustable two-stage structure for changing the length. The upper ends of the two telescopic rods 1 are fixedly connected by a connecting plate 2. The connecting plate 2 is provided with a screw hole for positioning and can be connected to the existing machine tool moving axis by bolts. The two telescopic rods 1 are fixed to the side of the heat dissipation component. A semicircular plate A3 is fixed to the bottom end of the two telescopic rods 1. The front and rear end surfaces of the semicircular plate A3 are elastically hinged with claws 4. The claws 4 are arc-shaped structures. A torsion spring is installed at the hinge between the claws 4 and the semicircular plate A3. A semicircular plate B5 is provided on the left side of the semicircular plate A3. The semicircular plates A3 and B5 have the same shape. The diameter of the middle position of the semicircular plates A3 and B5 is larger than that of the upper two end positions. The diameter of the semicircular plate B5 can be limited by the claw 4 and fit with the semicircular plate A3 to form a cylindrical structure. The bottom of the semicircular plate A3 is magnetically attracted with a collecting circle 6, and the collecting circle 6 can be magnetically attracted with the semicircular plate B5. The collecting circle 6 is concentrically arranged with the semicircular plates A3 and B5. The inner wall of the bottom end of the collecting circle 6 is gathered inward. A drain pipe 7 is installed at the bottom end of the collecting circle 6, and the drain pipe 7 is connected to the heat dissipation component. Multiple injection pipes 8 are transversely installed on the sides of the semicircular plates A3 and B5. The injection port of the injection pipe 8 is in the arc-shaped inner circle of the semicircular plates A3 and B5. The injection pipe 8 is in the middle position of the semicircular plates A3 and B5, and is in the position of its maximum diameter. The multiple injection pipes 8 are connected to the heat dissipation component by a water inlet pipe 9.

[0028] The heat dissipation assembly comprises a housing 10, and heat dissipation holes 11 are provided on the left and right sides of the housing 10;
