[0003] At present, in the process of management bidding, projection equipment is usually used in large-scale bidding meetings, detailed interpretation of bidding documents or real-time presentations. The existing management bidding projection equipment needs to be changed when used. Since bidding activities usually need to be conducted in different locations, the management bidding projection equipment needs to be disassembled so that the management bidding projection equipment can be carried. However, the existing management bidding projection equipment is usually fixed to the top of the bracket by bolts or screws.
