[0025] Working principle: When the present invention is used, the carburetor to be tested is first placed between the two fixed plates 7, and then the electric push rod 5 is opened, and the fixed plate 7 is driven to move by the extension of the movable end of the electric push rod 5, and the clamping force between the two fixed plates 7 is used to clamp and fix the carburetor, which is beneficial to the detection of the carburetor; then the retractable connector (the existing technology) on the carburetor air tightness tester body 4 is connected to the carburetor, and the carburetor air tightness test is performed on the carburetor using the carburetor air tightness tester body 4; When the gas seal of the carburetor meets the requirements, at this time, the electric push rod 15 is opened, and the strip block 18 is driven to move by the contraction of the telescopic end of the electric push rod 15, and the movement of the strip block 18 is divided into two processes: Process 1: Under the action of the squeezing spring 1 22, the movable block 23 moves synchronously with the strip block 18, thereby driving the rectangular plate 30 to move, thereby driving the short cylinder 31 and the circular ink filling box 29 to move; The short cylinder 31 initially moves along the smooth groove 2501. At this time, the circular ink-adding box 29 keeps moving horizontally, so that the circular ink-adding box 29 is separated from the marking head 35. As the rectangular plate 30 continues to move, the short cylinder 31 moves along the descending groove 2502, thereby driving the rectangular plate 30 to move downward, so that the circular ink-adding box 29 moves to the bottom of the marking head 35. When the rectangular plate 30 moves to the two ends of the rectangular opening, the rectangular plate 30 will not move any further, and at this time, the baffle 24 is in contact with the connecting frame 10; Process 2: As the strip block 18 continues to move, the baffle 24 will be driven to move, and then the connecting frame 10 will be driven to move, thereby driving the rectangular block 6 to move. As the rectangular block 6 moves, the connecting rod 11 will be driven to move, so that the connecting rod 11 will first move along the parallel groove 1701, and then drive the slider 26 to move horizontally, thereby driving the sleeve 14, the movable rod 34 and the marking head 35 to move horizontally; as the connecting rod 11 continues to move, the connecting rod 11 will move along the lifting groove 1702, and then drive the slider 26 to move upward, thereby driving the sleeve 14, the movable rod 34 and the marking head 35 to move upward, so as to achieve the lifting of the marking head 35, thereby ensuring that the marking head 35 is coplanar with the carburetor; finally, the connecting rod 11 enters the pushing groove 1703, so that the slider 26 keeps moving horizontally, thereby driving the sleeve 14, the movable rod 34 and the marking head 35 to move horizontally, so that the marking head 35 contacts the carburetor, thereby marking the carburetor; After the carburetor is marked, the movable end of the electric push rod 15 is extended to drive the bar block 18 to reset, and then under the action of the extrusion spring 22 and the reset spring 13, the rectangular block 6 is reset first, so that the connecting rod 11 moves along the push groove 1703, the lifting groove 1702 and the parallel groove 1701, and finally the marking head 35 is horizontally retreated first, then descended, and finally moved to the initial position; when the marking head 35 moves to the initial position, at this time, as the bar block 18 continues to reset, the movable block 23 is separated from the rectangular plate 30, and then under the action of the reset spring 2 32, the circular ink adding box 29 is first raised and covered on the marking head 35, so that the marking head 35 is in contact with the ink in the circular ink adding box 29, so as to add ink to the marking head 35, so as to print a clear mark on the carburetor; When the detected carburetor is unqualified, at this time, the electric push rod 15 will not move, so the carburetor will not be marked; finally, the qualified carburetor or the unqualified carburetor is determined by observing the mark on the carburetor.

[0026] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
