[0026] The present invention is described in detail below in conjunction with specific embodiments.

[0027] In the present utility model, when directional words appear, they are used to facilitate the description of the utility model and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present utility model.

[0028] In the present invention, unless otherwise specified and limited, when terms such as "disposed on", "connected" and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figures 1 to 4 As shown, a coffee powder tamper comprises a handle 10, a connecting rod 20, a pressing block 30, a pressing block cover plate 40 and a spring 21.

[0030] The handle 10 is made of steel, wood or aluminum alloy. An inner cavity 11 opened to one end is provided inside the handle 10 , and the inner cavity 11 is a circular slot.

[0031] One end of the connecting rod 20 is inserted into the inner cavity 11 and connected to the handle 10 , which can be a close-fitting plug-in connection or a threaded connection.

[0032] The pressing block 30 is a cylinder, and is vertically fixedly connected to the other end of the connecting rod 20. A plurality of annular grooves 31 are provided at the bottom of the pressing block 30 at intervals along its radial direction. The diameter of the annular grooves 31 gradually increases from the inside to the outside, forming a thread-like pressing groove, which can make the coffee powder cake present a thread shape after pressing, making the extraction pressure more balanced and the extraction speed more stable, thereby extracting coffee with a better taste.

[0033] The pressing block cover plate 40 is stacked on the pressing block 30, and a guide sleeve 41 is vertically arranged on the pressing block cover plate 40.
