Abstract

This utility model relates to the field of outrigger structure technology, and in particular to a self-locking outrigger mechanism and auxiliary trolley. It includes a mounting base and an outrigger body. The outrigger body includes a control component, a first outrigger, and a second outrigger. The control component includes a control button, a first control switch, and a second control switch. A first locking component is installed inside the first outrigger, and a second locking component is installed inside the second outrigger. The first control switch is connected to the first locking component, and the second control switch is connected to the second locking component. The control button allows the outrigger body to move relative to each other. When the control button is not pressed, the outrigger body is locked. This utility model provides easy and smooth operation, meeting the needs of supporting equipment to work in any position or fixed location. After pressing and holding the control button, the external equipment is pulled to the desired position and angle, and then the control button is released to complete the suspension and fixation of the external equipment.
