[0032] The first linkage assembly 110 includes a support block 111 and two guide blocks 112 . The two guide blocks 112 are fixed to opposite sides of the support block 111 by bolts, and a guide groove 113 is provided on the inner side of the guide block 112 . The connecting block 210 is inserted into the guide groove 113 and abuts against the cross tube 200 .

[0033] It should be noted that the engine fixing front beam is assembled by welding multiple components; the first linkage assembly 110 and the second linkage assembly 120 are both connected to the base 100 by bolts, and the bearing bracket 150 is also connected to the base 100 by bolts;
