Abstract: The disclosure is a nut structure for an electric pushing rod. The electric pushing rod has a guide screw (A) with an outer thread (A1). The nut structure includes a metal cylinder (10) and a plastic intermediate component (20). The metal cylinder (10) has a pivot hole (11) being passed through by the guide screw (A). An inner wall of the pivot (11) is provided with an inner thread (12). The plastic intermediate component (20) covers the inner thread (12) and is disposed of between the outer thread (A1) and the inner thread (12). The plastic intermediate component (20) includes a fixed side thread (21) mounted on the inner thread (12) and a driving side thread (22) screwed with the outer thread (A1). Therefore, the strength may be enhanced to avoid both the nut structure from being broken and the driving side thread (22) from getting stripped.

Abstract: An actuator having a manual rotating mechanism and an anti-pinch mechanism includes an actuating body, a manual rotating mechanism, and an anti-pinch mechanism. The actuating body has a stretchable tube. The manual rotating mechanism has a sleeve assembly and a manual rotating wheel. The sleeve assembly has a central shaft and a connecting plate. The anti-pinch mechanism has a clutch wheel which is fixed to the stretchable tube and is movably sleeved around the central shaft. When the stretchable tube is blocked during a retraction stroke, the clutch wheel is detached from the connecting plate such that the clutch wheel follows the stretchable tube to idle. Therefore, the stretchable tube can be manually rotated to retract and the anti-pinch effect during the stretchable tube being retracted can be achieved.

Abstract: A linear actuator (1) and the centrifugal safety device (50) thereof is disclosed. The safety device (50) includes an outer socket (51) having a stop portion (512) and a first accommodation portion (513), an inner socket (53) having a raised portion (531) and a second accommodation portion (532) and a centrifugal assembly (55) having a centrifugal block (551) and an elastic element (555). The inner socket (53) drives the centrifugal assembly (55) to rotate. If the centrifugal force of the centrifugal block (551) is smaller than the elasticity of the elastic element (555), then the centrifugal block (551) is limited in the second accommodation portion (532) by the elastic element (555), or else the centrifugal block (551) moves into the first accommodation portion (513) and clamped by the raised portion (531) and the stop portion (512).
