Thus, the front end of the wheel-type auxiliary 20 can be fixed without shaking in the horizontal and vertical directions.
As shown in fig. 2, 3, 10 and 11, the hook 142 of the rear hook 140 is guided by the guiding opening 222a to enter the slot 222 b. As mentioned above, the hook 142 is embodied as a post, and the end of the post forms a stop 142 a. Wherein the diameter of the catch is smaller than the width of the slot 222b and can move in the slot 222b, and the diameter of the stop 142a is larger than the width of the slot 222b, so that the stop 142a is buckled below the slot 222 b. Then, the hook 142 pushes the latch 224a to move to the closed end of the slot 222b, and the elastic element 226 allows the latch 224a to return to the latching position, so as to fix the hook 142 of the rear hook portion 140 in the slot 222 b. In this way, the rear end of the main bracket 110 is also fixed, thereby fixing the entire vehicle-mounted fixing device 10 to a designated area and stably fixing the wheel-type assistive device 20.
