[0029] To realize that the opening of the rotatable planting groove 2c is upward in the static state, the shaft tube 2b is fixed on the base plate 2a through a support, the left and right sides of the rotatable planting groove 2c are provided with shaft rings 2f, the shaft rings 2f are movably sleeved on the shaft tube 2b, the shaft tube 2b supports the rotation of the rotatable planting groove 2c to make the opening of the rotatable planting groove 2c upward, the bottom surface of the rotatable planting groove 2c is a circular arc surface, which does not contact the surface of the base plate 2a in rotation, as Figure 5 shown, when the base plate 2a is installed obliquely, the opening of the rotatable planting groove 2c can also be upward.
