The utility model relates to a sampler. The utility model relates to a sampler, in particular to an intertidal zone surface sediment sampler. The device comprises a sampling rod, a mud sampler and a screen, the mud sampler is a hollow container, one side of the mud sampler is provided with a sample inlet, the other side of the mud sampler is provided with a discharge port for discharging internalseawater, the discharge port is provided with the screen, and the bottom edge of the sample inlet extends outwards relative to the top edge, namely the sample inlet is an inclined plane and inclines outwards from top to bottom; the sampling rod is a telescopic rod, the lower end of the sampling rod is connected with the other side of the bottom sampler, and the upper end of the sampling rod is a handheld end. According to the utility model, the telescopic sampling rod and the mud sampler matched with the telescopic sampling rod are arranged, so that the sampler can be suitable for complex andchangeable sampling sites of intertidal zone surface sediments, the collection of surface sediment samples with set depth and set quantity is realized, the operation is simple, and the sampling quality is high; meanwhile, carrying and using are convenient.
