1. A connection device, for connecting a control box of a fracturing apparatus with a mounting base of the fracturing apparatus, the fracturing apparatus further comprising a transmission component, the transmission component comprising a transmission shaft, wherein the connection device comprises:
a fixation rack, configured to be fixedly connected with the mounting base;
a box connection mechanism, configured to be connected with the control box, and drive the control box to move at least from a first position to a second position relative to the fixation rack;
wherein, when the connection device is connected with the mounting base and the control box is located at the first position, the control box is located at a side of the transmission component in a direction perpendicular to an axis of the transmission shaft and a distance between the control box and the transmission component is less than a predetermined distance, and during the control box being moved from the first position to the second position, the control box is away from the transmission component to form an operation space for the transmission component at the first position.
