The primary roller (34) and the secondary roller (36) are movably arranged in the primary matching groove (37) and the secondary matching groove (38), respectively.

8. The aisle stacker with convenient fork angle adjustment according to claim 7, characterized in that: The primary roller (34) and the secondary roller (36) are both sleeved and mounted on the mounting shaft, and the side walls of the primary roller (34) and the secondary roller (36) are both provided with oil guide holes (39). The movable seat body (17) is provided with a primary oil storage groove (42), and an oil passage (43) is provided on the side of the primary oil storage groove (42) in the lower direction. A force column groove (44) is provided at the lower end of the oil passage (43), and an annular oil groove (45) is provided on the side wall of the force column groove (44). The bottom of the force column groove (44) is connected to a force column (46) via a support spring (46). 47), the lower side end of the force-bearing column (47) is hemispherical, and an oil guide groove (48) is provided on the side wall of the force-bearing column (47). When the support spring (46) is in a reset state, the oil guide groove (48) and the annular oil groove (45) are not connected. When the force-bearing column (47) is fully pushed into the force-bearing column groove (44), the oil guide groove (48) and the annular oil groove (45) are connected, so that the lubricating oil flows out along the oil guide groove (48) to lubricate the primary roller (34). The oil guide holes (39) are all embedded with oil-absorbing cotton cores (65).

9. The aisle stacker with convenient fork angle adjustment according to claim 8, characterized in that: A limiting block (52) is integrally formed on the side wall of the load-bearing column (47); an annular groove (49), an insertion groove (50) and a limiting groove (51) are provided on the side wall of the load-bearing column groove (44); the insertion groove (50) and the limiting groove (51) are symmetrically arranged in a group, and the insertion groove (50) and the limiting groove (51) are both arranged in communication with the annular groove (49); when the load-bearing column (47) is actually installed, the limiting block (52) is pushed into the limiting groove (51) along the insertion groove (50) and the annular groove (49); and when the load-bearing column (47) is completely pushed into the load-bearing column groove (44), the limiting block (52) does not separate from the limiting groove (51).

10. The aisle stacker with convenient fork angle adjustment according to claim 9, characterized in that: The fork arm (18) is provided with a secondary oil storage groove (53), and the lower edge of the secondary oil storage groove (53) is provided with a lubrication structure for lubricating the secondary roller (36), and the lubrication method of the lubrication structure is the same as the lubrication method of the primary roller (34).
