As shown in Figure 1, in some embodiments of the invention, described actuator can comprise windlass 1051, roller 1052 and wireline 1053. Displacement coding unit 1061 has rotation axis, and the rotation axis of windlass 1051 and the rotation axis of displacement coding unit 1061 can coaxially be arranged. That is, the rotation axis of windlass 1051 and the rotation axis of displacement coding unit 1061 can synchronous axial system, the displacement of transport trolley 104 on walking track 103 can be calculated. One end of wireline 1053 can be connected with the rotation axis of windlass 1051, and the other end of wireline 1053 can be connected with transport trolley 104, and wireline 1053 can stride across roller 1052. Thus it is possible not only to make the structure of described feeding device more reasonable, and displacement coding unit 1061 can be made more accurately to calculate the displacement of transport trolley 104 on walking track 103.
