This application discloses a coffee tamper for use with a coffee funnel. The tamper includes: an upper body having a through first chamber with ball grooves formed in the wall of the first chamber; a pressure plate surrounding one end of the upper body, the pressure plate having a second chamber with a plurality of graduated grooves arranged vertically on the wall of the second chamber; a ball assembly disposed within the ball grooves and capable of engaging with the graduated grooves as the upper body moves downwards vertically; and a lower body surrounding the other end of the upper body for connecting the upper body and the pressure plate. This application features a reasonable structural design, achieving precise pressure control and multi-flavor extraction through the innovative design of the ball assembly-gradient groove feedback system and reset structure.

This invention discloses a device for correcting the tilt of a transmission tower in a mining area, comprising a base, a fixed support assembly on the base, a support seat connected to the fixed support assembly, a tower fixing seat connected to the support seat, and a tower mounted on the tower fixing seat. A detection alarm assembly is connected to the middle of the bottom wall of the support seat, and a correction assembly is movably connected to the upper wall of the base. A self-positioning locking assembly is provided on the upper wall of the base, and an adjustment assembly is provided on the self-positioning locking assembly. The self-positioning locking assembly and the adjustment assembly are located at the lower end of the support seat. This invention belongs to the field of transmission tower correction technology, and particularly relates to a device for correcting the tilt of a transmission tower in a mining area. The detection alarm assembly can detect and control the tilt of the tower, and the correction assembly can correct the tilt of the tower and simultaneously fix the corrected tower, reducing the use of jacks.
