1. A detection apparatus, comprising:
a main body;
a detection component, wherein the detection component comprises:
a signal transmitter configured to transmit a detection signal;
a signal receiver configured to receive at least a portion of the detection signal transmitted by the signal transmitter; and
a connection part including a U-shaped structure or a C-shaped structure, wherein the U-shaped structure or the C-shaped structure allows a detection object to be located in an opening of the U-shaped structure or an opening of the C-shaped structure, wherein the connection part connects the signal transmitter and the signal receiver, and the signal transmitter and the signal receiver are spaced apart from each other by the connection part, and the signal transmitter and the signal receiver are respectively fixed on opposite branches of the U-shaped structure, or opposite branches of the C-shaped structure;
a detection object receiving part including limit posts configured to receive a detection object, wherein the detection object receiving part and the detection component are relatively movable on the main body transversely along the arrangement of a guide rail of the detection component, to allow a detection object received by the detection object receiving part to be located in a transmission path of the detection signal between the signal transmitter and the signal receiver, and the guide rail is fixed on the main body, wherein the detection component is movably arranged on the guide rail; and
a driver drivingly connected with the detection component to drive the detection component to move along the guide rail; wherein the driver comprises:
a motor with an output shaft;
a lead screw, wherein the lead screw is connected with the output shaft of the motor to rotate under the drive of the motor, and the lead screw is parallel to the guide rail; and
a screw nut, wherein the screw nut is threadedly engaged with the lead screw and is movably arranged on the lead screw, and the screw nut is connected with the detection component and drives the detection component to move along the guide rail.
