As shown in fig. 3, the center fixing base 11 includes a seat plate 111, two vertical plates fixed on left and right opposite sides of the seat plate 111, two wing portions 113 located outside the two vertical plates, and a handle 117 connecting upper portions of the two vertical plates, rear contact portions 1121 contacting the rear surface of the tailgate 2 are provided below the two vertical plates, positioning holes 1131 for penetrating the height fine adjustment assembly 14 are provided on the wing portions 113, and lower contact portions 1132 contacting the upper surface of the tailgate 2 are provided below the wing portions 113. The two vertical plates are divided into a first vertical plate 112a and a second vertical plate 112b, and a first bearing 114 is provided on the first vertical plate 112 a.
The lower contact portion 1132 and the rear contact portion 1121 are portions that come into contact with the surface of the tailgate 2, and therefore, are preferably made of an elastic material so as not to scratch the surface of the tailgate 2 during assembly. The height fine adjustment assembly 14 is inserted into the hole of the tail plate 2 through the positioning hole 1131, and the lower contact portion 1132 of the wing portion 113 contacts the upward surface of the tail plate 2. Because the center of gravity of the center fixing base 11 is located at the rear, the center of gravity of the center fixing base 11 tends to swing, and the rear contact portion 1121 contacts the rear surface of the tailgate 2 under the moment of gravity, so that the whole adjusting device 1 is hung on the tailgate 2, and thus an operator does not need to hold the adjusting device 1 by one hand but can operate by two hands during fine adjustment, and the operation is convenient. The handle 117 provides a force application position of the holding and releasing adjusting device 1, and increases the connection between the first vertical plate 112a and the second vertical plate 112b, so that the structure of the central fixing seat 11 is more stable.

The U-shaped stopper 1211 plays a role in left-right and rear stoppers for the outer wall of the tail gate lock 3. In order to completely fix the tail gate lock 3 with the clamping limiting plate 121, the quick clamp 123 needs to be operated to move the T-shaped driving block 124 backward. Because both the clamping jaws 125 are of a lever type structure with a middle rotation, the clamping jaws 125 swing synchronously and clamp the tail door lock 3 from the left and right sides in cooperation with the driving post 1251 and the driving hole 1241. The head of the limit bolt keeps the T-shaped driving block 124 against the lower surface of the clamping limit plate 121, and the longitudinal guide waist holes 1242 enable the T-shaped driving block 124 to slide back and forth only under the limit of the limit bolt.
