A guide rod 6 is provided on each side of the base 3 corresponding to the telescopic hole; each end of the guide rod 6 has a mounting hole, which facilitates the fixed installation of the cylinder to an external location.

[0034] In the same cylinder assembly, front covers 7 are respectively installed between the inner cavities of the cylinder barrels 11 of two adjacent individual cylinders 1, between the inner cavity of the foremost cylinder barrel 11 and the base 3, and between the inner cavity of the rearmost cylinder barrel 11 and the rear cover 4.
