[Prior Art] In order to operate the opening or closing of a shutter such as a disconnect switch, a spring operator is used. Fig. 4 is a perspective view showing a conventional spring actuator for a shutter. The spring actuator for the shutter operates the opening or closing of the disconnecting switch through an operating rod coupled to a connecting rod mounted on the output shaft. In Fig. 4, the gear motor 1 is decelerated by using the worm wheel 4 which is connected to the worm shaft 2 directly coupled to the output shaft of the gear motor 1, and the elbow is engaged by the 4a, 5a of the engaging portion. The lever 5 rotates the worm wheel 4. Further, instead of the gear motor 1, the manual operation knob 4 may be coupled to the operation shaft 2d of the helical gear 2b. With the rotation of the toggle lever 5, the compression end is fixed and the one end is coupled to the toggle spring 8 on the toggle lever 5. When the toggle lever 5 and the toggle spring 8 become a line forming a dead point, the timing spring 8 can reach the maximum compression amount' and then when the toggle lever 5 is rotated beyond the dead point of the toggle spring 8, The toggle spring will begin to release energy and the toggle lever 8 will move quickly. At this time, the engagement of the toggle lever 5 with the worm wheel 4 will be released, and the force of the energy released by the toggle spring 8 drives the toggle lever 5, and the engaging portion 5b and the lever 9 of the toggle lever 5 are engaged. The engagement of the engaging portion 9a is applied to the driving lever 9 and the output shaft 1 is driven by a fork-shaped fork 1 2 which is engaged with the roller 10 of the -5-(2) 1272629 provided on the lever 9. 1. The opening/closing of the disconnecting switch 14 is operated by an operating lever 15 coupled to the connecting rod 1 of the output shaft 1 1. Fig. 5 is a view showing the load moment of the conventional spring operator and the output torque characteristic of the operator. In the conventional spring operator system, at the dead point, when the output shaft starts to move, the spring of the toggle spring is heavy and the arm of the toggle lever is small, but when the output shaft stops moving, the arm of the toggle lever is large. The load of the toggle spring is small, so the torque of the toggle lever will become a mountain-shaped feature with a spike on the way. On the other hand, the load characteristic applied to the shutter of the spring operator is that a large torque must be required at the beginning of the stroke or at the end of the stroke, so that the fork is transformed into a bathtub having a bottom in the middle of the activity. [Characteristics of the Invention] [Problems to be Solved by the Invention] The load characteristics of the shutter are as shown in Fig. 5, and the characteristics at the time of opening and closing are quite different. On the other hand, the torque characteristics that are changed by the forks must have the same characteristics when opening and closing, and excessive torque will be generated at the beginning of the stroke and at the end of the stroke. Question. (1) Since the unnecessary energy is released, the spring load will become more than necessary, and the size of the operator will also become larger. -6 - 1272629 (3) (2) Since excessive torque will occur at the end of the stroke, the buffer will tend to be a large buffer. (3) The loss due to the sliding friction of the fork portion is very large. Therefore, the present invention provides a spring actuator for a shutter which can provide a torque characteristic of a load corresponding to a torque characteristic of a load. [Means for Solving the Problem] The present invention is directed to interconnecting a rotatable toggle lever and a toggle spring, and the toggle lever and the toggle spring form a dead point when the toggle lever is rotated. When the toggle lever rotates beyond the aforementioned dead point, the toggle lever will quickly start moving, and the spring operator of the shutter is operated by the rotation of the output shaft driven by the toggle lever to operate the opening or closing of the shutter. A relay shaft and a connecting rod are arranged between the toggle lever and the toggle spring. With the setting of the lever angle of the relay shaft, the output torque characteristic can be arbitrarily set to realize the torque characteristic of the corresponding load. It has the characteristics of changing the torque characteristics of the output shaft with different rotation directions, so that when the rotation direction of one side is larger than the initial stage of rotation, the rotation direction of the other side is the initial stage of rotation than the end of rotation. Small output shaft torque characteristics. [Embodiment] Fig. 1 is a perspective view of a spring operator of the present invention. Although in the first figure, the vicinity of the gear motor and the worm shaft are not shown in the drawing, they will be mutually inconsistent with the conventional spring operator -7-(5) 1272629 shown in Fig. 4. Engage. The operating rod 15 of the disconnecting switch 1 4 is connected to the connecting rod 1 3 . Next, the spring operator of the present invention will be described. Fig. 2 (a) to (b) are schematic views showing the state in which the toggle lever and the toggle spring are changed. If the gear shaft 2 is rotated by the gear motor 1 or the manual handle 2 c from the closed state, the hammer 4 will start to rotate by the engaging portion 4a of the worm wheel 4 and the toggle lever 5 The engagement of the engaging portion 5 a can rotate the toggle lever 5 in the clockwise direction. When the rotation of the toggle lever 5 is transmitted through the coupling lever 6, the relay lever 7 is rotated in the counterclockwise direction, and the toggle spring 8 is compressed. (Refer to Fig. 2 (〇) With the rotation of the smashing wheel 4, the toggle lever 5 will continue to rotate.] When the lever 5 and the connecting rod 6 become in line, the toggle lever 5 will become The dead point state in which the moment has no effect. (Refer to Fig. 2 (b) When the rotation further exceeds this dead point, the direction of rotation of the relay lever 7 will be reversed to a clockwise direction, and the toggle spring 8 will be in a compressed state. Released, the accelerated toggle lever 5 is rotated clockwise, the connecting rod 13 is rotated clockwise, and the disconnecting switch 14 is switched to open by the operating rod 15 connected thereto. The present invention, as shown in Fig. 3, has the feature of "changing the torque characteristics of the output shaft with different directions of rotation", which can be obtained as a son-in-law when the rotation direction of a certain side is the initial stage of rotation compared with the end of rotation, .... -9 - (6) 1272629 The output shaft torque characteristic is smaller than the end of the rotation. [Effect of the Invention] The present invention provides a relay shaft and a connecting rod between the toggle lever and the toggle spring, by setting The angle of the connecting rod of the shaft By setting the output torque characteristics, the torque characteristics of the corresponding load can be realized. Since the release of unnecessary energy can be suppressed, the operator can be made smaller, because it can suppress excessive torque at the end of the stroke.
