  The linear drive module includes a linear rail, a slider, and a plurality of steel balls. The linear rail has at least two rail grooves, and screw rods are provided in two end blocks and are provided in parallel to the linear rail.

In addition, even when changing to a linear rail of a different size, if two end blocks of different sizes are not manufactured again, the end of the linear rail is made to correspond to the original drive means via the newly manufactured end block. Since it cannot be coupled, extra replacement is required when replacing the screw rods and linear rails of different sizes in the linear drive module, which complicates the entire assembling and transporting operations.

  The linear drive module of another embodiment of the present invention further includes an adapter set that can be engaged with linear rails of different sizes, and the distance between the first slider of the adapter set and the adapter board is adjusted with a screw. As a result, the distance of the widening or reducing of the plurality of second sliders relative to the first slider can be linked, and the size of the adapter set is adjusted accordingly. The linear drive module can be coupled directly to the original end block and driving means by the size adjustment function of the adapter set without having to replace the end block and driving means with a new one. Therefore, the manufacturing cost can be reduced, and the assembly, transportation work and time can be reduced. At the same time, the coupling is protected against collision by the slider operation, the stability of the coupling drive and the freedom of assembly of the linear rail. The degree can be improved. In addition, the adapter slider set of the adapter set can be finely adjusted due to the characteristics that the coupling size can be finely adjusted.
