However, when such a thin blade is bumped, the blade may be shattered by the recoil force. During the rotation of the grinding disc joint, the fragments rotate against the wall in the grinding disc joint, resulting in an unstable center of gravity of the grinding disc joint, which affects the normal operation of the grinding disc joint. This embodiment provides the following technical solutions:

[0020] A ventilated resin grinding disc joint, comprising a grinding disc joint 1, an air inlet slot 2 is provided on the grinding disc joint 1, a convex block 3 is provided on the outer side of the grinding disc joint 1 at a position corresponding to one end of the air inlet slot 2, and also comprising an air catching slot 4, the air catching slot 4 is provided on the convex block 3, a pad 7 is provided on the grinding disc joint 1, an anti-slip rubber strip 8 is provided on the grinding disc joint 1, an auxiliary through hole 5 is provided on the grinding disc joint 1, a resin grinding disc 9 is provided on the upper end of the grinding disc joint 1, and a connecting bolt hole 10 is provided on the resin grinding disc 9 at a position corresponding to the auxiliary through hole 5, a connecting flange 12 is provided on the lower end of the grinding disc joint 1, a connecting pipe 14 is provided on the end of the connecting flange 12 away from the grinding disc joint 1, the connecting pipe 14 and the connecting flange 12 are integrally arranged, a second connecting thread 15 is provided on the inner wall of the end of the connecting pipe 14 away from the connecting flange 12, and the second connecting thread 15 is integrally arranged with the inner wall of the connecting pipe 14;

[0021] In this embodiment, please refer to Figure 1-Figure 3When the staff places the resin grinding disc 9 on the cushion block 7, the fixing bolt is inserted from the lower end of the grinding disc joint 1 into the secondary through hole 5, through the grinding disc joint 1 until it is inserted into the connecting bolt hole 10 opened on the resin grinding disc 9, and the connection between the resin grinding disc 9 and the grinding disc joint 1 is completed. Because the resin grinding disc 9 is in direct contact with the cushion block 7, the cushion block 7 raises the height of the resin grinding disc 9 so that there is a gap between the resin grinding disc 9 and the grinding disc joint 1. Therefore, when the grinding disc joint 1 and the resin grinding disc 9 rotate, the wind catching groove 4 on the protrusion 3 will capture air and allow the air to enter the air inlet groove 2. The air is in The friction between the grinding disc joint 1 and the resin grinding disc 9 is increased, and the connection between the resin grinding disc 9 and the grinding disc joint 1 is more stable. The staff can insert the output end of the rotating motor into the connecting pipe 14, and the external thread on the output end of the rotating motor and the second connecting thread 15 in the connecting pipe 14 are engaged with each other to realize the connection between the grinding disc joint 1 and the rotating motor.

[0022] In this embodiment, a bolt 13 is provided on the connecting flange 12, and the bolt 13 penetrates the connecting flange 12 and extends into the grinding plate joint 1. The bolt 13 is threadedly connected to the grinding plate joint 1.

Because the resin grinding disc 9 is in direct contact with the cushion block 7, the cushion block 7 raises the height of the resin grinding disc 9 so that there is a gap between the resin grinding disc 9 and the grinding disc joint 1. Therefore, when the grinding disc joint 1 and the resin grinding disc 9 rotate, the wind catching groove 4 on the protrusion 3 will capture air and allow the air to enter the air inlet groove 2, and the air Air flows between the grinding disc joint 1 and the resin grinding disc 9, dissipating heat and cooling the resin grinding disc 9 and providing good ventilation effect. The height of the anti-slip rubber strip 8 is connected to the height of the pad 7 and is also in contact with the resin grinding disc 9, which can increase the friction between the resin grinding disc 9 and the grinding disc joint 1, making the connection between the resin grinding disc 9 and the grinding disc joint 1 more stable. The staff can insert the output end of the rotating motor into the connecting pipe 14, and engage the external thread on the output end of the rotating motor with the second connecting thread 15 in the connecting pipe 14 to achieve the connection between the grinding disc joint 1 and the rotating motor.
