Through the setting of the second bearing 17, the second adjusting rod 11 can be rotated more smoothly on the adjustment platform 2. The outer ends of the first adjusting rod 10 and the second adjusting rod 11 are fixed with rotating hand wheels 22. Through the setting of the rotating hand wheels 22, the first adjusting rod 10 and the second adjusting rod 11 are convenient to rotate, thereby bringing convenience to the staff.

[0030] like Figure 4 As shown: the bottom of the top plate 3 is symmetrically provided with an "L"-shaped mounting plate 18. It should be noted that: the mounting plate 18 is connected to the top plate 3 by bolts 23. Through the setting of the bolts 23, the two mounting plates 18 can be disassembled, and the bottoms of the two mounting plates 18 are fixed with the inside of the same adjustment box 12. The inside of the adjustment box 12 is installed with a clutch transmission assembly 13 used in conjunction with the first adjustment rod 10 and the second adjustment rod 11.

It should be noted that the backs of the first bevel gear 131 and the second bevel gear 132 are both provided with an annular groove 137 with a "convex" shape in cross section, and a rotating ring 138 is rotatably installed inside the annular groove 137, and the two rotating rings 138 are respectively fixed to the adjustment box 12, through the annular groove 137 and the rotating ring 138 The cooperation can install the first bevel gear 131 and the second bevel gear 132 on the inner wall of the adjustment box 12, and the first bevel gear 131 and the second bevel gear 132 are transmission connected through the third bevel gear 133, and the third bevel gear 133 is located at the upper part of the first bevel gear 131 and the second bevel gear 132, and a mounting ring 139 is fixed on the top of the third bevel gear 133, and the mounting ring 139 is rotatably connected with the mounting shaft 1311 through the first bearing 1310, and the mounting shaft 1311 is fixed to the top of the adjustment box 12, and the third bevel gear 133 is installed through the arrangement of the mounting ring 139, the first bearing 1310 and the mounting shaft 1311.

[0032] It should be noted that the inner end of the second adjusting rod 11 extends to the adjusting box 12 and is fixedly connected to the second bevel gear 132 , so that the second bevel gear 132 can drive the second adjusting rod 11 to rotate.

[0033] It should be noted that: the inner end of the first adjusting rod 10 extends to the adjustment box 12 and is equipped with a pin 136, and a first slot 134 for use with the pin 136 is opened at the center of the first bevel gear 131, and the first slot 134 is a through hole; the center of the second bevel gear 132 is provided with a second slot 136 for use with the pin 136, and the second slot 135 is a blind slot.

[0034] In the initial state, the latch 136 is located between the first bevel gear 131 and the second bevel gear 132 and is disengaged from the first slots 134 and the second slots 135 , so that the first adjustment rod 10 and the second adjustment rod 11 can rotate independently on the adjustment platform 2 .

[0035] When the latch 136 is inserted into the second slot 135 , the first adjusting rod 10 and the second adjusting rod 11 can rotate on the adjusting platform 2 in the same direction.

[0036] When the latch 136 is inserted into the first slot 134 , the first adjusting rod 10 and the second adjusting rod 11 can rotate on the adjusting platform 2 in opposite directions.

[0037] A rotating cylinder 15 is fixed to the inner side of the adjustment platform 2, and the first adjustment rod 10 is sleeved in the rotating cylinder 15 and arranged coaxially, an annular protrusion 14 is fixed on the first adjustment rod 10, and compression springs 16 sleeved on the first adjustment rod 10 are respectively arranged on both sides of the annular protrusion 14. It should be noted that: the opposite ends of the two compression springs 16 are connected to the annular protrusion 14, and the opposite ends of the two compression springs 16 are respectively fixedly connected to the inner end wall of the rotating cylinder 15 and the inner side wall of the adjustment platform 2. Through the arrangement of the annular protrusion 14, the rotating cylinder 15 and the compression spring 16, the first adjustment rod 10 is reset.

[0038] When the connection terminals of the two voltage transformer bodies 5 are connected by a flexible conductive element 6 (flexible conductive connecting wire), the voltage transformer bodies 5 can be adjusted in the following two ways: first, the two voltage transformer bodies 5 are adjusted separately (since the adjustment methods of the two voltage transformer bodies 5 are the same, this application only describes the adjustment method of the voltage transformer body 5 on the right); second, the two voltage transformer bodies 5 are adjusted simultaneously in opposite directions;

[0039] like Figure 1-3 As shown: if the voltage transformer body 5 on the right side is to be adjusted: the first adjusting rod 10 is rotated, the first adjusting rod 10 can drive the gear 9 on the rear side to rotate, because the gear 9 is meshed with the rear gear rod 8, the gear 9 can drive the rear gear rod 8 to move inside the two slide rails 19 during the rotation process, and the rear gear rod 8 can also drive the right adjustment plate 4 to move left and right through the mounting seat 7 during the movement, so that the adjustment plate 4 can drive the voltage transformer body 5 on the right side to be adjusted left and right.

[0040] If the two voltage transformer bodies 5 are adjusted simultaneously in opposite directions: first, the first adjusting rod 10 is pulled, and the first adjusting rod 10 can drive the annular protrusion 14 and the latch 136 to move during the pulling process; the annular protrusion 14 can squeeze the compression spring 16 close to the inner wall of the adjustment platform 2, and the compression spring 16 at this time changes from the original state to the compressed state, and the latch 136 can be inserted into the first slot 134; then the first adjusting rod 10 is rotated, and the first adjusting rod 10 can drive the first bevel gear 131 to rotate through the latch 136, and the first bevel gear 131 is rotated by The third bevel gear 133 drives the second bevel gear 132 to rotate. Since the first bevel gear 131 and the second bevel gear 132 rotate in opposite directions, the first bevel gear 131 and the second bevel gear 132 can respectively drive the first adjusting rod 10 and the second adjusting rod 11 to rotate in opposite directions. The first adjusting rod 10 and the second adjusting rod 11 can respectively drive the gear 9 to rotate in opposite directions. The two gears 9 respectively drive the gear rod 8 to move in opposite directions. The two gear rods 8 drive the voltage transformer body 5 through the adjustment plate 4 to be horizontally adjusted in opposite directions.

[0041] When the connection terminals of the two voltage transformer bodies 5 are connected by a rigid conductive element 6 (rigid metal connecting piece), the two voltage transformer bodies 5 can be adjusted in an equidistant manner in the following manner to prevent the rigid conductive element 6 from being damaged due to the continuous increase or decrease in the distance between the voltage transformer bodies 5;

[0042] When the two voltage transformer bodies 5 are adjusted equidistantly: push the first adjusting rod 10, the first adjusting rod 10 drives the annular protrusion 14 to move and can also drive the latch 136 to move, so that the annular protrusion 14 can squeeze the compression spring 16 close to the first bevel gear 131, and the compression spring 16 at this time changes from the original state to the compressed state, and the latch 136 can be inserted into the second slot 135; then rotate the first adjusting rod 10, the first adjusting rod 10 drives the second bevel gear 132 to rotate through the latch 136, and the second bevel gear 132 can rotate the second adjusting rod 11. Since the first adjusting rod 10 and the second adjusting rod 11 have the same rotation direction, they can drive the two gears 9 to rotate in the same direction at the same time. The two gears 9 drive the adjustment plate 4 to move equidistantly through the gear rod 8 respectively, and the two adjustment plates 4 can drive the voltage transformer body 5 to move equidistantly to prevent the hard conductive element 6 from being damaged due to the continuous increase or decrease in the spacing between the voltage transformer bodies 5.
