INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field The present invention relates to a linear actuator having a quick release device, which is applied to a machine for reciprocating motion of extending and retracting. The quick release device is designed to restore the load without the need for a power source. [Prior Art] The general linear actuator is mainly composed of a motor, a power output shaft, a transmission shaft, a screw shaft, a nut and an inner tube. First, the motor transmits the rotational torque to the output force, because the output shaft and the transmission shaft The axial torque is coupled to transmit the rotational torque of the output shaft to the drive shaft, and the drive shaft is provided with a screw shaft, the screw shaft is sleeved with a nut and the nut is connected with the inner tube; when the screw shaft is driven When the shaft rotates, the nut converts the rotational force of the screw shaft into a linear thrust or pulling force, so that the inner tube makes a reciprocating motion of extending or retracting to drive the load to achieve linear actuation. However, in the absence of a power source or in an emergency, if the inner tube of the linear actuator and the load on the linear actuator need to be quickly retracted, the linear actuator must have a manual mechanical quick release mechanism. The traditional quick release mechanism, such as the European patent EP0685662, designs the quick stomach release mechanism into a coupling type, and places the coupling between the transmission shaft and the screw shaft, so when it is to be loose, the coupling That is, the separation causes the motor, the output shaft and the transmission shaft to be separated from the screw shaft, the nut and the inner tube; thus the screw shaft can freely rotate within the nut, thereby causing the inner tube to retract. Due to the quick release mechanism of the coupling type, the load will be almost instantaneous when it is loose.

INSTRUCTIONS (2) The inner tube is retracted, thus causing considerable impact on the load and the linear actuator itself, and is liable to cause damage. Another conventional quick release mechanism, such as U.S. Patent No. 6,158,295, uses a brake-type quick release mechanism design that improves the impact of the load and the internal tube, thereby improving the impact. However, this type of loosening mechanism must include a planetary gear set; when loose, the internal teeth and the planetary gears revolve around the sun teeth in addition to the rotation, and the loosening of the slider also requires the conversion of the axial force into a diameter. The force is so strong that the mechanism design is complicated, and the loosening mechanism must cooperate with the linear actuator to design the planetary gear set to add the loose-rug mechanism, thus limiting the scope of use of the loose-release mechanism. In summary, the quick release mechanism of the conventional linear actuator is necessary for improvement. SUMMARY OF THE INVENTION The present invention provides a linear actuator with a quick release device that linearly retracts the load without the need for a power source supply = controllable speed and distance of the recovered load. It is designed to interrupt or divert the power transmission from the power source to the load, and then rely on the weight of the load to quickly recover the negative φ load. The design of the linear actuator mainly includes: a power device for driving the power of the rotary torque; a transmission device for transmitting power to the negative portion including the screw shaft, the nut and the inner tube, The screw shaft is connected to the power device to transmit power, and the nut is sleeved on the screw shaft to convert the rotational torque into a squat motion, B ^ and the inner tube is fixed on the nut and move with the 嫘 cap; a load joint,

The nut 35 fastens the release handle 36 to the line of the quick release mechanism for outputting the rotational torque device 20, and the transmission device 20, and the transmission device 20 and the screw shaft 21 are coupled to the dynamic screw shaft 2 1 to rotate the torsion nut 22 The upper end of the front end of the nut 22 and the shaft release spring 33 are detached from the load joint 40 which is axially sleeved with a ball bearing 32 and the front end of the load joint 40. Actuator stereo decomposition power source, the motor will be placed 20 from the screw shaft load joint 40 between the powerful device 10 to transfer power to linear transport, the inner tube 23 rear sleeve 3 1 outer diameter sleeve The outer diameter of the release handle 3 6 ; the outer diameter of the tight fit, tight fit, and the bearing; finally the use of the buckle 41 to help; wherein the power unit 10 drives the screw nut 22 to convert the rotary motion into linear motion, so that The linear movement of the screw t from the inner tube 23 on the 22 is pushed out or retracted. Between the inner tube "and the load joint 40 is provided with a quick release device 3 〇, which coaxially engages the inner tube" and 5, the invention description (5) the load joint 40, the quick release dream and the loose spring 33 The fixing member 30 is mainly composed of a rotating portion and a non-rotating portion==nail is a bearing 32=:=3 is connected to a non-rotating portion of the ball shaft 2=two: loose; the fixing nut 35 is axially sleeved on the load joint 4. The fixed shaft is combined with the rotating disc and the rotating disc is not 斿, and the load is connected to the load (not shown) by the connecting hole 42 on the gas, the detachment and the head 4 . The rotation part and the non-rotation part can also be loosened, and the negative figure 3 is a detailed view of a part of the detail of FIG. 2; wherein the other end of the two release springs 33 of the quick release spring 33-end has an inner folding hook 331 to fix m And the right ice aunt 勹 ^ 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上Tight force. Because the loose spring "two folds = two fixed on the load joint 40, when the loose spring 33 332 is not pulled, the torsion force will cause the release spring 33 to be inwardly received, resulting in loosening the sleeve 31 on the tightness 2 when causing The outer diameter of the loose sleeve 31 and the ball bearing 32 of the rotating portion are combined with the non-rotating portion to be in a non-rotatable state, and the power is transmitted to drive the load to move; however, if the loose spring is pulled, the hook 3 32 is used. When the elastic spring 33 is loosened, when the spring tightening force on the loose sleeve 31 is smaller than the force required for the combination of the rotating portion and the non-rotating portion, the outer diameter of the rotating sleeve 31 and the ball bearing 32 of the rotating portion That is, it is in a rotatable state away from the restriction of the non-rotating portion. At this time, a force is generated due to the weight of the load, and the force causes the nut 1288215 to be invented (6) 22 (Fig. 2), the inner tube 23, and the loose shaft.
