Specifically, protective shell 17 is a circular hollow structure with one end open, the open end of protective shell 17 is provided with a through hole, the open end of protective shell 17 extends into base 6, and base 6 is also provided with a through hole 65, and a mounting bolt is penetrated between the through hole of protective shell 17 and the through hole 65 of base 6 to realize the fixed connection between protective shell 17 and base 6.

[0026] As Figure 5As shown, the lower end of the rotating shaft 2 is fixedly connected with the auxiliary switch 14. Specifically, the top of the auxiliary switch 14 has a concave plate 13 which is a component of the auxiliary switch 14, and the bottom of the rotating shaft 2 has a third boss 12 which is connected with the concave plate 13 in a clamping manner, thereby realizing the fixed connection and synchronous rotation of the rotating shaft 2 and the concave plate 13. When the rotating shaft 2 rotates, the third boss 12 drives the rotation of the concave plate 13, and the auxiliary switch 14 can sense the angle of rotation of the rotating shaft 2. The auxiliary switch 14 is a prior art. In addition, in order to avoid the shaking of the rotating shaft 2, a shaft sleeve 9 is arranged between the base 6 and the rotating shaft 2. The inner wall of the shaft sleeve 9 is in contact with the outer wall of the rotating shaft 2, and the outer wall of the shaft sleeve 9 is in contact with the inner wall of the base 6, thereby preventing the rotating shaft 2 from shaking in the base 6.

[0027] As shown in Figure 7 , the base 6 has two second bosses 64, and the second bosses 64 have screw holes 641. As shown in Figure 6 , a screw rod 15 is installed on the screw hole 641. The upper end of the screw rod 15 extends into the screw hole 641, and the lower end of the screw rod 15 extends into a U-shaped opening 16 on the auxiliary switch 14. A nut is installed on the lower end of the screw rod 15 to hold the auxiliary switch 14, thereby realizing the fixed connection of the auxiliary switch 14 and the base 6.

[0028] The first pin shaft 4 is vertically fixed on the rotating shaft 2, and the second pin shaft 5 is arranged on the first pin shaft 4 and parallel to the rotating shaft 2. Specifically, the first pin shaft 4 penetrates the rotating shaft 2 and the pressing plate 3 to realize the fixed connection with the rotating shaft 2. One end of the first pin shaft 4 has a nut, and the second pin shaft 5 penetrates the other end of the first pin shaft 4. The second pin shaft 5 is in sliding connection with the first pin shaft 4, that is, the second pin shaft 5 can penetrate the first pin shaft 4 or be pulled out of the first pin shaft 4. The rotating shaft 2 and the pressing plate 3 are located between the nut on the first pin shaft 4 and the second pin shaft 5.

[0029] As shown in Figure 7 , the base 6 has a plurality of adjustment holes 62 located on the same circumference, and the lower end of the second pin shaft 5 penetrates the adjustment hole 62 and has a lock hole 51 for hanging a lock. As shown in Figure 5 , the outer wall of the lower end of the rotating shaft 2 is fixedly connected with a limiting plate 11. As shown in Figure 6 , the outer wall of the limiting plate 11 has an extension 111 extending radially outward. As shown in Figure 7As shown, the base 6 has four first bosses 63, the first bosses 63 have limiting holes 631, the four limiting holes 631 are located on the same circle, and the limiting bolts are inserted into two limiting holes 631 of the four limiting holes 63 to limit the rotation angle of the limiting plate 11. When the limiting plate 11 rotates with the rotating shaft 2, after the extension part 111 contacts with the stationary limiting bolt in the limiting hole 631, the limiting bolt blocks the rotation of the limiting plate 11, thereby limiting. By installing the limiting bolt in different limiting holes 631, the rotation of the manual mechanism can be limited to 90°, 135° and 180°.

[0030] In order to facilitate the installation of the whole manual mechanism, as shown, Figures 1 to 4 The side wall of the base 6 has a mounting plate 61, and the base 6 is fixedly connected with other components through the mounting plate 61. The mounting plate 61 of the base 6 has a circular hole for penetrating a bolt to assemble with other components.

[0031] In order to ensure good sealing, the upper end of the base 6 and the rotating shaft 2 have an oil seal 7. The inner wall of the oil seal 7 is in close contact with the rotating shaft 2, and the outer wall of the oil seal 7 is in close contact with the base 6.

[0032] In order to realize waterproof, the top of the base 6 has a waterproof cover 8, and the rotating shaft 2 penetrates the waterproof cover 8. The waterproof cover 8 is buckled on the top of the base 6, and the waterproof cover 8 is in contact with the outer wall of the rotating shaft 2. The oil seal 7 is located on the inner side of the waterproof cover 8, and the oil seal 7 is in close contact with the waterproof cover 8.

[0033] In order to realize the positioning between the rotating shaft 2 and the base 6 along the axis of the rotating shaft 2, a check ring 10 is arranged on the rotating shaft 2 above the limiting plate 11, and the check ring 10 is in contact with the bottom of the base 6.

[0034] The working principle of the utility model is: when in use, the second pin shaft 5 is pulled out by opening the lock, the rotating shaft 2 and the first pin shaft 4 are rotated by rotating the vertical connecting rod 1, the first pin shaft 4 is aligned with the corresponding adjusting hole 62 on the base 6, the second pin shaft 5 is inserted, and the lock 19 is locked. Correspondingly, the two limiting bolts installed on the limiting hole 631 to limit the rotation of the limiting plate 11 are also adjusted to the corresponding position, so that the disconnecting switch can accurately and reliably complete the opening and closing operation. The operator only needs to slightly rotate to change the position of the first pin shaft to complete the opening and closing operation. The four adjusting holes on the base can ensure that the rotating angle is suitable for various opening and closing operations. The utility model discards the traditional way of rotating the rotating shaft to block the groove on the base by pulling the operating rod to realize opening and closing. The structure of the utility model is simpler, and the appearance is beautiful and easy to operate.
