The invention discloses a spinning machine facilitating quick replacement of a machine needle. The spinning machine structurally comprises a machine body, a needle clamp, a presser foot, a base and ahand wheel disc; the bottom surface of the machine body is fixedly connected with the top surface of the base, and the hand wheel disc is installed at one side of the machine body. Compared with the prior art, the spinning machine has the advantages that there is no need to use an external tool, the replacement speed is high, the sewing progress is not affected, the installed machine needle can bekept perpendicular to a worktable, an operator does not need to hold the machine needle with one hand and conduct fixing operation with the other hand, the operation is more convenient, the hands canbe effectively prevented from being pricked by the machine needle, and the safety of installing the machine needle is greatly improved; the spinning machine can adapt to machine needles of differentneedle models and clamp the machine needles well, ensure that the installed machine needle is aligned with an opening seam of the presser foot, help to improve the spinning process and effectively prevent that the machine needle is misaligned and rigidly pressed broken by the presser foot.
