The M365421 flexible cord body 50 is locked to the positioning seat 45 of the outer tube 44, thereby causing flexibility (4) 5〇 to the first pulley 32 to the outer tube 44. Pulling out at the open end (as shown in the eighth figure) causes the guide rod 3 to rise from the outer tube 44; and when the guide rod 30 is raised, the second pulley 34 is raised to make the flexibility The cord body 50 pulls the end 52 and the fixing seat 411 such that the first rod member 51 projects from the jaw member 42. Continuing the above action, since the length of the long rod 621 is approximately equal to the extension limit state B to the extension limit 62, when the screw 23 is pulled out from the scale rod to the extreme position, the suspension nut The 622 pulls the long rod 621 away from the extension limit switch 62, so the extension limit switch 62 can issue a stop signal to prevent the motor 2〇 from excessively rotating. The flexible cord body 50 is loosened, and the whole set of mechanisms is pressed by the weight of the gravity or the bed and the table, and the action of the fine return is achieved. When the screw 23 is rotated to the end position of the retraction, the guide seat is top-touched. The object # 631 is exposed at the end of the sensor holder 61, and the short rod 631 is pressed against the retraction limit switch 63 to cause the bicycle to stop. Although the case is based on the best implementation of the reward, but the skilled person can do a variety of different forms of change without the spirit of the case. The above embodiments are intended to be used only to limit the scope of the present invention. All kinds of changes or changes that are not in violation of the spirit of the case are all within the scope of the patent. 7 M365421 [Simple description of the diagram] The first figure is a plan view of a known actuator.
