Through such an arrangement, the center of the dotting can be marked with a cross so that the position can be accurately determined.
[0023] The diameter of the sponge part is larger than the diameter of the connecting part. The bottom end of the support plate 1 is located on one side of the telescopic sleeve 2 and is fixedly installed with an extrusion feeding hopper 4. The feed end and the discharge end of the extrusion feeding hopper 4 are respectively connected and penetrated with a one-way valve 5. The one-way valve 5 at the feed end is connected and penetrated with a feed pipe 6. The feed pipe 6 extends to the upper surface of the support plate 1. The connecting end of the one-way valve 5 at the discharge end is connected and penetrated with a discharge pipe 7.
