In one embodiment, the mains voltage reaches 10V to 36V after passing through the voltage reducer 31. In one embodiment, the mains voltage reaches 12V after passing through the voltage reducer 31.

In this way, the fourth resistor can protect the output terminal of the voltage comparator 36.
Further, referring to fig. 2 to 8, as an embodiment of the power supply circuit control device provided by the present invention, the tightness adjusting mechanism includes: a first through hole arranged on one conical sleeve 1, a second through hole arranged on the adjacent conical sleeve 1, a rod-shaped nut 41 which is provided with a threaded hole and can pass through the first through hole and the second through hole, and a screw rod 42 which is arranged in the first through hole and the second through hole and can be in threaded connection with the rod-shaped nut 41; the rod nut 41 has a length greater than the diameters of the first and second through holes. Thus, a first through hole is formed in the side wall of one conical sleeve 1, a second through hole is formed in another adjacent conical sleeve 1, the rod-shaped nut 41 can pass through the first through hole and the second through hole and then reach the inner side of the other conical sleeve 1, and the screw rod 42 sequentially passes through the first through hole and the second through hole and then is in threaded connection with the rod-shaped nut 41 so as to lock the two conical sleeves 1; the tightness of the contact between the two conical sleeves 1 can be varied according to the degree of locking of the screw 42.
Further, referring to fig. 2 to 8, as an embodiment of the power supply circuit control device provided by the present invention, the rod nuts 41 at two sides of the threaded hole are respectively provided with a wire passing hole 411. Thus, the rope 43 can pass through the thread holes 411 on both sides of the screw 42 nut, so that the rod nut 41 can be pulled by the rope 43 when passing through the first through hole and the second through hole.
In one embodiment, the extension direction of the wire through hole 411 is the same as the extension direction of the screw rod 42. Therefore, when the rope 43 passes through the thread passing hole 411, the screw rod 42 is not easily interfered in the traction process of the rope 43.
In one embodiment, referring to fig. 8, in the radial direction of the screw rod 42, any of the wire holes 411 is respectively located at the outer sides of the first through hole and the second through hole; thus, when the rope 43 passes through the first through hole and the second through hole and reaches the inside of the wire passing hole 411, the rope 43 can be opened towards the radial outer side of the screw rod 42, so that the rope 43 can be tensioned towards the center directions of the first through hole and the second through hole in the process of tensioning the rod-shaped nut 41, and the position stability of the rod-shaped nut 41 is improved. After the screw 42 is inserted into the first through hole and the second through hole, the rope 43 approaches the screw 42 from the outside of the tapered sleeve 1, then the rope 43 sequentially passes through the first through hole and the second through hole, the rope 43 passing through the second through hole extends to one of the thread passing holes 411 in a direction away from the screw 42, the rope 43 passing through one of the thread passing holes 411 winds around the outer side of the rod-shaped nut 41 to the other thread passing hole 411 and passes through the other thread passing hole 411, the rope 43 passing through the other thread passing hole 411 extends to the second through hole in a direction approaching the screw 42 and passes through the second through hole, the rope 43 passing through the second through hole passes through the first through hole again, and the rope 43 passing through the first through hole reaches the outside of the tapered sleeve 1 and extends in a direction away from the screw 42. In this way, in the process of pulling the two ends of the rope 43, since the rope 43 passing through the two wire passing holes 411 enters the second through hole in the direction close to the screw rod 42, the rope 43 can pull the rod-shaped nut 41 in the direction of the screw rod 42, and the rod-shaped nut 41 is prevented from being separated from the screw rod 42; because the two ends of the rope body 43 are respectively opened towards the direction departing from the screw rod 42, the rope body 43 is not easy to interfere with the movement of the screw rod 42 in the traction process.
In one embodiment, two adjacent tapered sleeves 1 are respectively provided with a cross mark, so that the two adjacent tapered sleeves 1 can be spliced and aligned with each other when being sleeved with each other.

In one embodiment, first ring body 513 is disposed in the area of a side of the first plate body. In one embodiment, in the axial direction of first ring body 513, the closest distance from first ring body 513 to the edge of the first plate body is less than the radius of first ring body 513; therefore, the deformation in the axial direction of the first ring body 513 can be transmitted to the edge of the first plate body as soon as possible to release, and the axial bending and fracture of the first ring body 513 caused by the overlarge stress in the axial direction of the first ring body 513 are avoided.

In one embodiment, the axial direction of the first pin body 511 passes through the axis of the first ring body 513; in this manner, first pin 511 is easily and evenly transferred to first ring 513 during traction. In one embodiment, at least one corner of the first rectangular side surface is located between the screw rod 42 and the corner of the first rectangular contact surface, and the distance between the corner of the first rectangular side surface and the corner of the first rectangular contact surface is a first stress transfer distance D1, and the distance between the corner of the first rectangular side surface and the screw rod 42 is a first stress release distance K1, D1 being less than K1, such that stress is sufficiently transferred between the first ring body 513 and the first plate body to be released and thereby reduce the influence on the screw rod 42. In one embodiment, D1 is exp (-K1) × Sin (K1/D1), such that the distance ratio between D1 and K1 decreases exponentially, such that as K1 is greater, D1 can decrease exponentially, such that as K1 increases, the closer upper corners of first ring body 513 and the closer upper corners of the first plate body can be closer together to relieve stress more quickly, reducing the amount of stress transferred to the bolts by first ring body 513; in addition, the distance between D1 and K1 has a sinusoidal fluctuation, and the periodic adjustment during adjustment of the different first ring bodies 513 enables D1 and K1 to change the rate of change between D1 and K1 during adjustment to reduce the resonance generated between the different first ring bodies 513.
