[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-2, a needle grinding machine which is convenient for height adjustment comprises a body 1 and a grinding needle 9. A switch 2 is installed on the front of the body 1. A guide column 3 is fixedly connected to the upper surface of the body 1. A top plate 4 is installed at one end of the guide column 3 away from the body 1. A lifting seat 5 is slidably connected to the outer surface of the guide column 3. A tightening rod is connected to the internal thread of the lifting seat 5, and a rotary handle 6 is fixedly connected to one end of the tightening rod. A first shell 7 is installed on the outer surface of the lifting seat 5. A first driving motor is installed inside the first shell 7. A connecting column 8 is fixedly connected to the output end of the first driving motor. The grinding needle 9 is fixedly sleeved on the outer surface of the connecting column 8. When the rotary handle 6 is turned, the tightening rod can be driven to rotate accordingly. When the tightening rod is tightened, the lifting seat 5 can be limited. When the tightening rod is turned, the limit of the lifting seat 5 can be released, so as to facilitate the adjustment of the height of the grinding needle 9. After starting the first driving motor, the grinding needle 9 can be driven to rotate.
