In this way, both the hydraulic oil introduced into the first connecting member 51 through the first opening 1102 and the hydraulic oil introduced from the second portion 11012 can be split, so as to prevent the hydraulic cylinder 10 from being mismatched with the type of the hydraulic motor 20, so that the flow rate of the hydraulic oil introduced into the hydraulic motor 20 is too large to damage the hydraulic motor 20.
Preferably, the first connecting element 51 is embodied as a three-way tube.

Specifically, when the movable member 12 relatively moves inside the oil chamber 1101 to decrease the spatial dimension of the first portion 11011 and increase the spatial dimension of the second portion 11012, since the fourth check valve 64 blocks the introduction of hydraulic oil into the third port 5203, the hydraulic oil inside the first portion 11011 passes through the first opening 1102 and is guided to the first port 5101 by the first check valve 61, and at this time, since the third check valve 63 blocks the introduction of hydraulic oil into the third opening 1104 by the third port 5103, the hydraulic oil inside the first port 51 is discharged from the second port 5102, enters the motor chamber 2101 by the first port 2102 and is discharged from the second port 2103, enters the second port 52 by the first port 1103 and is guided to the second check valve 62 by the second port 5201 and is guided to the second port 5203 by the second port 5201, and is guided to the second port 5212 by the second port 62.

Likewise, when the movable member 12 relatively moves within the oil chamber 1101 to decrease the spatial dimension of the second portion 11012 and increase the spatial dimension of the first portion 11011, since the second check valve 62 obstructs the introduction of hydraulic oil into the second port 5202 by the second opening 1103, hydraulic oil within the first portion 11011 passes through the third opening 1104 and is guided to the third communication port 5103 by the third check valve 63, at which time hydraulic oil within the first port 51 is discharged from the second communication port 5102, enters the motor chamber 2101 by the first port 2102 and is discharged from the second port 2103, enters the second port 52 by the first port 5201 and is guided to the fourth check valve 64 by the third port 3, and is guided to the fourth port 5201 by the fourth check valve 64 through the fourth port 5201 and is guided to the fourth port 5211 by the fourth port 1105.
In this process, hydraulic oil always enters the motor chamber 2101 through the first port 2102 and is discharged through the second port 2103, so that the rotation direction of the rotation shaft 22 rotated by the hydraulic oil is always kept consistent, and the rotation speed of the rotation shaft 22 is controlled within a predetermined range.
