The pillars 11 may include tour primary pillars 111 corresponding to corners of the cartridge. All of the primary pillars 111 have the same height. In other embodiments, the pillars 11 may include a plurality of secondary pillars (not shown) arranged between the primary pillars 111. Each of the connecting rods 12 connects two adjacent primary pillars 111.
The bearing platform 2 includes supporting pads 21 arranged on the top of each of the primary pillars 111. Preferably, the dimension and the shape of the supporting pads 21 are substantially the same. In the embodiment, the dimension of the cross sections of the supporting pads 21 is larger than that of the primary pillars 111. The supporting pads 21 include a supporting piece 213 and a contacting piece 214. The supporting piece 213 is arranged between the primary pillars 111 and the contacting piece 214. The supporting piece 213 may be made by metallic materials with high strength. The contacting piece 214 may be made by materials with buffer capabilities, such as rubbers.
The contacting piece 214 of each supporting pads 21 includes a bearing portion 211 and an abutting portion 212. The abutting portion 212 is higher than the bearing portion 211. Each of the bearing portions 211 is for supporting one corner of the cartridge, and the abutting portion 212 is for preventing the cartridge from moving horizontally. In the embodiment, each abutting portion 212 includes two stopper arms 215 higher than the two abutting portions 212 in the vertical direction, and the two abutting portions 212 are vertical to each other. In other embodiments, the abutting portion 212 may include one stopper arm 215, and the direction of the stopper arm 215 of each of the supporting pads 21 may be adjusted to prevent the cartridge from moving horizontally.
