[0017] The present utility model will be further described below in conjunction with the accompanying drawings:

[0018] Embodiment 1:

The front and rear sides of the right side of the shaft rod 1 are fixedly connected to the left sides of two straight plates 4 respectively. Control structures 2 are connected to the inner sides of both straight plates 4. Installation structures 3 are connected to the front and rear ends of the outer wall of the shaft rod 1 respectively. A plurality of electric control box circuit breakers 6 are connected to the outer wall of the shaft rod 1. The model of the electric control box circuit breaker 6 is selected according to the usage requirements. A bracket 5 is connected to the bottom of the installation structure 3.

[0020] The control structure 2 includes a first screw rod 201 and a cylinder 202. The front and rear ends of the first screw rod 201 are fixedly connected to the inner sides of two straight plates 4 respectively. The inner wall of the cylinder 202 is threadedly connected to the outer wall of the first screw rod 201. The cylinder 202 rotates forward and backward on the outer wall of the first screw rod 201 under force. A sleeve 203 is rotatably connected to the outer wall of the cylinder 202. The sleeve 203 rotates on the outer wall of the cylinder 202 through a bearing under force. A cross plate 204 is fixedly connected to the right side of the sleeve 203. A second screw rod 205 is threadedly connected to the inner wall of the cross plate 204. The second screw rod 205 rotates left and right on the inner wall of the cross plate 204 under force. A plurality of round openings 207 are machined on the outer wall of the cylinder 202. The inner wall of the round opening 207 on the right side is inserted into the left side of the outer wall of the second screw rod 205. A handle 206 is fixedly connected to the right side of the second screw rod 205. The handle 206 facilitates driving the second screw rod 205 to rotate.

[0021] By making the handle 206 drive the second screw rod 205 to rotate to the right through the cross plate 204 in the control structure 2, the left side of the second screw rod 205 is disengaged from the corresponding round opening 207. Then, the cylinder 202 rotates on the outer wall of the first screw rod 201, changing the position of the cylinder 202 to prevent the cross plate 204 from conflicting with the installation location. Subsequently, the sleeve 203 rotates to the right on the outer wall of the cylinder 202, making the cross plate 204 face to the right. Then, the handle 206 drives the second screw rod 205 to rotate to the left, inserting the left side of the outer wall of the second screw rod 205 into the corresponding round opening 202 on the outer wall of the cylinder 202, reducing the usage difficulty of the floating interface drive shaft assembly for the electric control box circuit breaker and eliminating the usage limitations.

[0022] The installation structure 3 includes a bearing block 301 and a bottom plate 302. The inner walls of the two bearing blocks 301 are fixedly connected to the front and rear ends of the outer wall of the shaft rod 1 respectively. Bearings are provided on the inner walls of the bearing blocks 301, and thus the shaft rod 1 is fixedly connected thereto and can rotate. The left and right sides of the bearing block 301 are fixedly connected to the inner sides of the bottom plate 302 respectively. The front and rear sides of the top of the bottom plate 302 are fixedly connected with cushion plates 303. The cushion plates 303 are iron washers. The bottoms of the bearing block 301 and the bottom plate 302 are both in contact with the top of the bracket 5.

[0023] Working principle:

[0024] Installation of the floating interface drive shaft assembly of the electric control box circuit breaker:

[0025] First, rotate the grip 206 with the second screw 205 to the right through the cross plate 204, so that the left side of the second screw 205 disengages from the corresponding round opening 207. Then, rotate the cylinder 202 on the outer wall of the first screw 201 to change the position of the cylinder 202 to prevent the cross plate 204 from conflicting with the installation location. Subsequently, rotate the sleeve 203 to the right on the outer wall of the cylinder 202 to make the cross plate 204 face to the right. Then, rotate the grip 206 with the second screw 205 to the left, so that the left side of the outer wall of the second screw 205 is inserted into the corresponding round opening 202 on the outer wall of the cylinder 202. Then, fit the bottoms of the bearing block 301 and the bottom plate 302 to the top of the bracket 5. Then, pass a bolt through the notch on the outer wall of the bottom plate 302 and thread it into the bracket 5 until the bottom of the nut of the bolt abuts against the top of the cushion plate 303. At this time, a frictional force is formed between the nut and the cushion plate 204.

[0026] Angle adjustment of the floating interface drive shaft assembly of the electric control box circuit breaker:

[0027] By swinging the cross plate 204 up and down, the cross plate 204 drives the cylinder 202 and the first screw 201 to swing through the second screw 205. Thus, the straight plate 4 drives the shaft rod 1 to rotate on the inner wall of the bearing block 301. The rotating shaft rod 1 drives the electric control box circuit breaker 6 to adjust the angle, thereby realizing the floating adjustment of the left interface of the electric control box circuit breaker 6.

[0029] Refer to the attached Figures 1-5 In this embodiment, a floating interface drive shaft assembly of an electric control box circuit breaker further includes a sheath 7. The inner wall of the sheath 7 is fixedly connected to the outer wall on the right side of the cross plate 204.

[0030] Working principle:

[0031] The sheath 7 can protect the hand through its rubber material to prevent scratches when the hand controls the cross plate 204.
