The present disclosure provides an adaptor, comprising an adapting bracket, an adapting member, and at least one locking component. The adapting bracket comprises a chute comprising two opposite sidewalls and a bottom wall. The bottom wall is disposed between the two sidewalls. The adapting member is disposed on the adapting bracket. The adapting member comprises an adapting interface and is in communicating with the chute. The at least one locking component is disposed in the adapting bracket. Each of the locking components comprises a locking member movably extending into the chute. When an electronic component is inserted in the chute, a mating interface of the electronic component is connected to the adapting interface, and the locking member is inserted into an engaging groove of the electronic component. By protecting the electronic component with the adapting bracket, it is possible to avoid damage to the electronic component from impacts.
