[0030] The two bearing bodies 2 each include a bearing seat 21 connected to the other end of the bracket body 11 , and a shaft sleeve 22 rotatably sleeved in the bearing seat 21 , and the shaft sleeve 22 is used to connect to the end of the main shaft 3 .

[0031] Specifically, the bracket body 11 is used to support the fixing plate 12, and the fixing plate 12 is used to connect with the pillar 4, so that the pillar 4 is used to support the cantilever bearing; the bracket body 11 is also used to support the bearing seat 21, and the bearing seat 21 is used to support the sleeve 22, and the sleeve 22 is used to support the end of the main shaft 3, so that the pillar 4 indirectly supports the end of the main shaft 3 through the cantilever bearing, thereby preventing the end of the main shaft 3 from forming a large bending moment, and the design requirements can be met without increasing the cross-sectional area of ​​the main shaft 3, and the cost is low. In order to facilitate the rotation of the sleeve 22 along the bearing seat 21, a clearance fit is preferably provided between the bearing seat 21 and the sleeve 22.

[0032] Further, such as Figure 2 The bracket body 11 includes a first pipe fitting 111, a second pipe fitting 112, a third pipe fitting 113 and a fourth pipe fitting 114 which are closed and connected in sequence, the fixing plate 12 is connected to the third pipe fitting 113, the bearing seat 21 is connected to the first pipe fitting 111, and the first pipe fitting 111 and the third pipe fitting 113 are arranged opposite to each other.

[0033] Specifically, the first pipe fitting 111 , the second pipe fitting 112 , the third pipe fitting 113 and the fourth pipe fitting 114 are used to jointly achieve the connection between the bearing seat 21 and the fixing plate 12 .

[0034] Further, such as Figure 2 The bracket assembly 1 also includes a reinforcing rod 13, one end of the reinforcing rod 13 is connected to the connection between the first pipe fitting 111 and the second pipe fitting 112, and the other end of the reinforcing rod 13 is connected to the connection between the third pipe fitting 113 and the fourth pipe fitting 114, or one end of the reinforcing rod 13 is connected to the connection between the first pipe fitting 111 and the fourth pipe fitting 114, and the other end of the reinforcing rod 13 is connected to the connection between the second pipe fitting 112 and the third pipe fitting 113.

[0035] Specifically, the reinforcing rod 13 is used to increase the strength of the bracket body 11. Since one end of the reinforcing rod 13 is connected to the connection between the first pipe fitting 111 and the second pipe fitting 112, and the other end of the reinforcing rod 13 is connected to the connection between the third pipe fitting 113 and the fourth pipe fitting 114, or one end of the reinforcing rod 13 is connected to the connection between the first pipe fitting 111 and the fourth pipe fitting 114, and the other end of the reinforcing rod 13 is connected to the connection between the second pipe fitting 112 and the third pipe fitting 113, it is equivalent to the reinforcing rod 13 being connected to the diagonal line of the bracket body 11, so that the bracket body 11 forms two triangular structures, thereby preventing the bracket body 11 from deforming.
