A detachable connection between the guard 101 and the spherical rear guard 100 is realized. Further, the rear surface of the spherical rear guard 100 is recessed toward the front guard 101 to form a mounting cavity 102, the mounting cavity 102 has an opening, the opening faces away from the front guard 101, and the opening is spherical. A mounting opening 105 is formed extending along the rear guard 100 toward the front guard 101 . Drive assembly 200 is removably mounted within mounting cavity 102 . When separating the rear spherical guard 100 and the driving assembly 200, the rear spherical guard 100 can be separated from the driving assembly 200 by moving it along a straight line, and the rear spherical guard 100 can be easily cleaned.

More specifically, as shown in FIGS. 2, 4, 6, and 7, the drive assembly 200 includes a mounting housing 210 and a first motor 220, the mounting housing 210 being removable into the mounting cavity 102. Connected as possible. Further, the outer surface of the mounting housing 210 is spherically structured for aesthetics of the overall appearance after the mounting housing 210 is installed in the mounting cavity 102 . After assembly, the outer surface of the mounting housing 210 aligns with the rear surface of the spherical rear guard 100 to form a complete spherical structure, and the mounting housing 210 can completely fill the opening of the mounting cavity 102 .

In this embodiment, the connection pole 215 provided close to the mounting portion 211 increases the force that the mounting portion 211 receives, and the support strength of the housing 213 is improved when the mounting portion 211 and the stand base 400 are connected. , thereby effectively preventing deformation of the housing 213 . In this embodiment, the first motor 220 can be installed in the housing 213 by locking it directly inside the front cover 214 or by fixedly installing it in the housing 213 .

Additionally, as shown in FIGS. 3 and 7, the mounting housing 210 is provided with a first planar surface 216 at its lower outer edge. The mounting portion 211 is provided on the first plane 216 . Since the mounting portion 211 obliquely supports the drive assembly 200 and the spherical rear guard 100, the mounting portion 211 exerts reaction forces on the mounting housing 210 in two directions, horizontal and vertical. According to the force decomposition, the supporting force received by the mounting housing 210 can be combined into an obliquely upward force. The supporting strength is higher and the amount of deformation is smaller than when the mounting portion 211 is directly connected to the spherical surface. The back surface of the spherical rear guard 100 is also provided with a second planar surface 104 aligned with the first planar surface 216 to form a planar surface having a circular cross-section.

Nor. In an embodiment in which the inclined surface 401 of the stand base 400 has an included angle of 45° with the horizontal surface, the rotating end 601 vertically penetrates the inclined surface, so the inclined surface 401 supports the rotating end 601 in the radial direction. . Thereby, the support rigidity of the inclined surface 401 with respect to the rotating end 601 is maximized, and the problem of deformation and depression of the upper surface of the stand base 400 is effectively avoided.
