[0024] The utility model is further explained in detail below in combination with the drawings and examples. Identical parts are denoted by identical reference numerals. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular part.

[0025] Referring to Figures 1 to 7 As shown in the figure, the power adapter assembly structure of the hand motor of the embodiment includes a lead sheath 1 and a lead transmission shaft 2. The lead sheath 1 is sleeved on the outside of the lead transmission shaft 2. A through hole is formed in the lead sheath 1 to facilitate the lead transmission shaft 2 to extend into the lead sheath 1. The end of the lead transmission shaft 2 towards the drive head 3 is buckled with the lead sheath 1. The lead sheath 1 and the lead transmission shaft 2 are connected by buckling, which increases the connection stability between the two. Without the need for additional parts to bind the two, the two are prevented from separating. The existing method binds the two with rubber bands to prevent them from separating. The buckling method eliminates the need for the use of springs and the installation of springs, thereby improving the installation efficiency.

[0026] The buckling method can be a clasp structure, a spring buckle, a concealed buckle or a thrust buckle.

[0027] The drive head 3 is connected to the outer tube of the hand motor by bolts. The bolts are evenly distributed along the circumference of the drive head 3, which increases the connection strength between the drive head 3 and the outer tube of the hand motor.
