A first groove portion 22 and a second groove portion 23 which are matched with the inclined portion 3021 are arranged on the handle base 2, the first groove portion 22 and the second groove portion 23 are formed by arranging grooves on the handle base 2, the extrusion plate 3 comprises a pre-hanging position and a locking position, when the extrusion plate 3 is in the pre-hanging position, the inclined portion 3021 is positioned in the first groove portion 22, the extrusion plate 3 is clamped in a part of the limit short groove 2101, and the deformation portion 301 is separated from the avoidance section 202; when the extrusion plate 3 is located at the locking position, the inclined part 3021 is located in the second groove part 23, the extrusion plate 3 is completely clamped in the limit short groove 2101, and the deformation part 301 is located at the avoidance interval 202 and presses the evaginable hook 102 and the mounting surface 201 against each other.

FIG. 12 is a schematic structural view of a third embodiment of a pre-hitch assembly of the present invention, wherein a lower extrusion plate is in a pre-hitch position; the difference from the first embodiment is that the extrusion plate 3 comprises two linear extrusion pieces which are arranged in parallel, and the two extrusion pieces are arranged separately; the pre-hanging assembly 21 comprises two groups of first upper table 2104 and second upper table 2105 which are respectively arranged at two sides of the supporting edge 203, wherein a limiting short groove 2101 which is correspondingly arranged is formed between the first upper table 2104 and the supporting edge 203 and between the second upper table 2105 and the supporting edge 203; the short limiting grooves 2101 are used for limiting the positions of the inner side edge and the outer side edge of the U-shaped extrusion plate 3 respectively; the tail parts of the two linear extrusion pieces are both provided with an extrusion elastic piece 302, and the extrusion elastic pieces 302 comprise an inclined part 3021; a first groove portion 22 and a second groove portion 23 which are matched with the inclined portion 3021 are arranged on the handle base 2, the first groove portion 22 and the second groove portion 23 are formed by arranging grooves on the handle base 2, the extrusion plate 3 comprises a pre-hanging position and a locking position, when the extrusion plate 3 is in the pre-hanging position, the inclined portion 3021 is positioned in the first groove portion 22, the extrusion plate 3 is clamped in a part of the limit short groove 2101, and the deformation portion 301 is separated from the avoidance section 202;

as shown in fig. 13, when the pressing plate 3 is in the locked position, the inclined portion 3021 is located in the second groove portion 23, the pressing plate 3 is completely engaged in the short limiting groove 2101, and the deformed portion 301 is located at the escape interval 202 and presses the inside-out hook 102 and the mounting surface 201 against each other.

The working principle is as follows: during installation, the extrusion plate 3 is placed on one side of the handle base 2 far away from the metal plate 1 of the automobile body, the first abdicating groove 303 and the second abdicating groove 304 are respectively staggered with the first upper table-board 2104 and the second upper table-board 2105, the inclined part 3021 of the extrusion plate 3 is positioned on a side bump forming the first groove part 22, the downward pressing inclined part 3021 and the extrusion plate 3 and the limit short groove 2101 are positioned at the same height, the extrusion plate 3 is pulled to one side of the second groove part 23 until the extrusion plate 3 is positioned in a pre-hanging position, the inclined part 3021 is positioned in the first groove part 22, at the moment, the partial clamping of the limit short groove 2101 is provided with the extrusion plate 3, the deformation part 301 is separated from the avoidance interval 202, and the pre-installation process of the extrusion plate 3 is completed.

When the handle base 2 and the automobile body metal plate 1 are installed, the outward turning hook 102 of the automobile body metal plate 1 penetrates through the avoidance section 202 to be abutted against the installation surface 201 at the corresponding position, then the extrusion plate 3 at the pre-hanging position is continuously pulled along one side close to the limiting edge 24 of the handle base 2 until the extrusion plate 3 is located at the locking position, the inclined part 3021 is located in the second groove part 23, the extrusion plate 3 is completely clamped in the limiting short groove 2101 at the moment, the deformation part 301 is located at the avoidance section 202 and presses the outward turning hook 102 and the installation surface 201 mutually, and at the moment, the whole installation process of the handle base 2 and the automobile body metal plate 1 is completed.
