Wherein the first reinforcing ribs 21 and the second reinforcing ribs 22 are commonly used to reinforce the region of the first body 11 where the first and second connection parts 13 and 14 are provided, so as to improve the structural strength of the region. By connecting the first reinforcing rib 21 and the second reinforcing rib 22, the first reinforcing rib 21 and the second reinforcing rib 22 can generate acting force with each other, so that the overall structural strength of the first main body 11 is improved, the first reinforcing rib 21 extends along the second direction to mainly generate supporting reinforcing effect in the second direction, and the second reinforcing rib 22 extends along the first direction to mainly generate supporting reinforcing effect in the first direction.
It can be appreciated that, because the stresses of the first body 11 in the first direction and the second direction are different, the thicknesses of the first reinforcing rib 21 and the second reinforcing rib 22 are set differently, and the thicknesses of the first reinforcing rib 21 and the second reinforcing rib 22 can be correspondingly set according to the stress conditions of the first body 11 in the first direction and the second direction, so as to realize a targeted reinforcing effect, avoid resource waste, and simultaneously intensively increase the structural strength of the position with larger stress.

It will be appreciated that when the number of the first reinforcing ribs 21 is plural, the plural first reinforcing ribs 21 may be disposed at intervals, and the stress is different due to the different connection positions between the plural first reinforcing ribs 21 and the first body 11, so that the thickness of each first reinforcing rib 21 may be different, and the reinforcing effect may be generated specifically. Similarly, when the number of the second reinforcing ribs 22 is plural, the plural second reinforcing ribs 22 may be disposed at intervals, and the stress is different due to the different connection positions between the plural second reinforcing ribs 22 and the second body 12, so that the thickness of each second reinforcing rib 22 may be different, and the reinforcing effect may be generated in a targeted manner.
In some examples, the number of first reinforcing ribs 21 is three and the number of second reinforcing ribs 22 is one.

Through so setting up can improve the strengthening effect of third strengthening rib 31 for two gusset 311 can have the interact, can jointly produce the strengthening effect, and because the position of being connected of two gusset 311 and second main part 12 is different, consequently the thickness of two gusset 311 also sets up differently, can produce the strengthening effect according to the atress is different to.
In some examples, the junction of the two ribs 311 is formed with a second cylindrical portion that can increase the strength of the junction of the two ribs 311, increasing the integrity of the two ribs 311. The angles of the included angles between the two rib plates 311 of each third reinforcing rib 31 intersecting each other may be set to be different, so that a reinforcing effect can be correspondingly generated for different positions of the second body 12.
