However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification. Embodiment

[0022] As Figures 1-5 shown, the present utility model provides a technical solution: a compact anti-loosening gear, which includes a gear disc 1. A plurality of tooth openings 2 are distributed on the outer side of the gear disc 1. A transmission shaft 3 is installed inside the gear disc 1. A notch 8 is opened on the outer side of the transmission shaft 3. Connecting sleeves 4 are symmetrically installed inside the notch 8. Installation blocks 7 are installed at both ends of a single connecting sleeve 4. Installation grooves 5 are opened at both ends of a single connecting sleeve 4. The installation grooves 5 are clamped with the installation blocks 7. A limiting groove 9 is opened on the inner side of the gear disc 1. The connecting sleeve 4 is installed inside the limiting groove 9. A plurality of docking blocks 12 are distributed on the side surface of the connecting disc 11. Docking grooves 10 are opened on both sides of the gear disc 1. The docking blocks 12 are arranged inside the docking grooves 10. A plurality of rubber strips 13 are distributed on the side surface of the connecting disc 11. The side surface of the connecting sleeve 4 is connected to the side surface of the connecting disc 11.

[0023] In this embodiment, by installing two connecting sleeves 4 inside the notch 8 and clamping the installation blocks 7 with the installation grooves 5, it is convenient to install the connecting sleeves 4, and the operation is convenient for maintaining and replacing the connecting sleeves 4. Then, the gear disc 1 is installed on the outer side of the transmission shaft 3, and the connecting sleeve 4 is clamped inside the limiting groove 9 opened on the inner side of the gear disc 1, effectively reducing the gap between the transmission shaft 3 and the gear disc 1, making the connection between the gear disc 1 and the transmission shaft 3 closer, making the transmission more accurate and stable, effectively avoiding the displacement of the gear disc 1 on the transmission shaft 3, reducing the fault shutdown time caused by the loosening of the gear disc 1, ensuring the stable operation of the gear disc 1. At the same time, with the cooperation of the connecting disc 11 installed on the outer side of the transmission shaft 3 and the docking blocks 12 clamped inside the docking grooves 10, it is beneficial to further ensure the stability between the gear disc 1 and the transmission shaft 3, effectively avoiding the loosening between the gear disc 1 and the transmission shaft 3.
