[0022] The bottom of the fixed seat 121 is fixedly connected to a base 211, and the bottom of the base 211 is fixedly connected to a slider 212. The slider 212 is slidably arranged inside the arc track 132. Two circular slide grooves are provided at the bottom of the slider 212. The two circular slide grooves are slidably connected to positioning blocks 213. The top of the positioning block 213 is fixedly connected to a spring 214.

[0023] A square vertical slot 14 is provided on the right side of the vehicle body 1, and the square vertical slot 14 is arranged below the fixed seat 121. A lifting seat 141 is slidably connected inside the square vertical slot 14, and a threaded rod 142 is threadedly connected at the center of the lifting seat 141. Connecting rods 143 are fixedly connected to the four corners of the top of the lifting seat 141. The top of the connecting rod 143 is fixedly connected to the bottom of the arc plate 131, and a bevel gear 1 421 is fixedly connected to the outer side of the bottom of the threaded rod 142. A motor 2 145 is fixedly connected to the right side of the vehicle body 1. Motor 2 The output end on the left side of 145 is fixedly connected with a bevel gear 2 451, which is meshed with the bevel gear 1 421; when the motor 2 145 is started and drives the bevel gear 2 451 to rotate, the bevel gear 2 451 will drive the threaded rod 142 to rotate through the bevel gear 1 421, and the threaded rod 142 will cause the lifting seat 141 to move upward or downward by rotating in different directions, and the lifting seat 141 will drive the arc plate 131 to move upward or downward through the connecting rod 143, thereby adjusting the height of the contact 124.

[0024] The bottom of the threaded rod 142 is rotatably connected to the bottom of the inner wall of the square vertical groove 14, and the top of the threaded rod 142 is rotatably connected to a stabilizing frame 144. The front and back sides of the stabilizing frame 144 are fixedly connected to the inner wall of the square vertical groove 14; the stabilizing frame 144 is used to support and limit the top of the threaded rod 142, so that the threaded rod 142 is more stable when rotating.

[0025] When in use, the vehicle body 1 is moved to the position required for testing, and the adjustment assembly 12 is in a state of being stored behind the test control device 11. At this time, the turning handle 314 is first turned counterclockwise to make it leave the curved plate 131, thereby releasing the fixation of the fixing seat 121, and then the fixing seat 121 is pushed to make the base 211 drive the slider 212 to slide in the curved track 132. At this time, the positioning block 213 is pushed into the slider 212 and squeezes the spring 1 214 to disengage from the positioning hole 312 on the left side of the curved plate 131. When the slider 212 is moved, the positioning block 213 is pushed into the slider 212 and squeezes the spring 1 214 to disengage from the positioning hole 312 on the left side of the curved plate 131. After the block 212 moves to the right side of the arc track 132, the fixing seat 121 is finely adjusted to move the positioning block 213 to the positioning hole 312 on the right side of the arc plate 131. Then, the positioning block 213 is elastically ejected into the positioning hole 312 by the spring 214. At this time, the fixing seat 121 is positioned. Finally, the turning handle 314 is turned clockwise to make it contact with the bottom of the arc plate 131, thereby fixing the position of the fixing seat 121. When the fixing seat 121 moves, the threaded shaft 313 moves in the arc groove 311. Then, the adjustment of the adjustment component 12 is controlled by operating the test control device 11. At this time, the motor 2 145 will be started first to drive the bevel gear 2 451 to rotate, and the bevel gear 2 451 will drive the threaded rod 142 to rotate through the bevel gear 1 421. The threaded rod 142 will make the lifting seat 141 move upward or downward through the rotation in different directions, and the lifting seat 141 will drive the arc plate 131 to move upward or downward through the connecting rod 143, so as to adjust the height of the contact 124. When the arc plate 131 moves, the stabilizing bar 133 will slide on the vehicle body 1. When the height adjustment is completed, the motor 1 222 is started again to drive the gear 223 to rotate counterclockwise. At this time, the gear 223 will drive the extension slide bar 123 to extend outward through the rack 231, and the extension slide bar 123 will slide in the fixed slide bar 122. The extension of the extension slide bar 123 will make the contact 124 move to the closed busbar for connection. This method can increase the moving distance of the contact 124, thereby meeting different needs. When the contact 124 is connected to the front and rear positions of the closed busbar, the contact 124 will drive the movable rod 1 232 to slide in the extended slide rod 123, and at the same time, the bottom of the movable rod 242 on the connecting block 241 will slide on the connecting frame 235 through the limiting shaft, and drive the spring 234 to stretch. This method can make the contact 124 have a certain activity space, and under the elastic effect of the spring 234, the access effect of the contact 124 can be improved and the situation of falling off can be reduced. When the contact 124 is connected in the up and down direction, the contact 124 will drive the connecting block 241 to slide on the movable rod 242 and squeeze the spring 3 243 to improve the access effect of the contact 124. Since the front side of the connecting block 241 is provided with a T-shaped slot, and the back side of the movable rod 1 232 is fixedly connected with a T-shaped limiting block, the front side of the connecting block 241 will slide on the T-shaped limiting block on the back side of the movable rod 1 232, thereby not affecting the movement of the connecting block 241. When the test is completed, the contact 124 is reset and the height adjustment of the arc plate 131 is reset. Then, the handle 314 is turned counterclockwise to release the fixation of the fixing seat 121, and then the fixing seat 121 is pushed to move the adjustment component 12 to the rear position of the test control device 11 for storage. At this time, the positioning block 213 on the slider 212 is inserted into the positioning hole 312 on the left side of the arc plate 131 to position the fixing seat 121. Then, the handle 314 is turned clockwise to make it contact with the bottom of the arc plate 131, thereby fixing the position of the fixing seat 121 and completing the storage work.
