This utility model discloses an assembled soil tamping device, including a handle and a tamping head. The tamping head has a threaded cylinder with four reinforcing ribs. A limiting hole is formed on the bottom side wall of the threaded cylinder. A threaded head is provided at the bottom of the handle, and a limiting mechanism is provided on the threaded head. The limiting mechanism includes an upper sliding cavity and a lower sliding cavity formed on the threaded head, and the two are interconnected. A sliding plate is provided inside the lower sliding cavity, and a spring is provided inside the lower sliding cavity at the bottom of the sliding plate. By setting the threaded cylinder and threaded head, an assembled connection between the handle and the tamping head is achieved, facilitating disassembly and assembly. During transportation and storage, the handle and the tamping head can be separated, reducing space occupation and making it easy to carry and store. The limiting mechanism, through the elastic force of the spring, causes the limiting head to automatically extend and insert into the limiting hole, achieving automatic limiting between the handle and the tamping head, preventing loosening of the threaded connection, and improving the stability and safety of the connection.

The utility model relates to the technical field of showcase lighting, specifically relates to a light guide plate mounting assembly suitable for showcase, including aluminium frame, limiting component, limiting component installs in one side of aluminium frame, and limiting component is used for fixed position of light guide plate, heat dissipation component, heat dissipation component installs in one side of aluminium frame, and heat dissipation component is used for heat dissipation. Compared with prior art, the application realizes automatic position limiting and firm fixing of light guide plate through the combination of limiting component and elastic compression structure, realizes the high -efficient heat dissipation of LED light source through the setting of heat dissipation component and air convection channel, prolongs light source life and guarantees the temperature stability inside showcase, and simultaneously, the installation and maintenance are simple and convenient, improve the uniformity and reliability of the overall lighting effect of showcase.

The invention relates to the technical field of flat wire production, and discloses a flat wire take-up machine which comprises a bottom plate, a rail arranged at the top of the bottom plate, a sliding seat slidably connected with the top of the rail and a rotating mechanism at the top of the sliding seat, the rotating mechanism comprises a rotating shaft, a first disc body and a take-up reel, and the rotating shaft is arranged at the top of the sliding seat through a bearing seat; the first disc body is arranged at one end of the rotating shaft, and the second disc body is fixed to one end of the first disc body. A fourth transmission wheel is fixed to the outer side wall of the rotating shaft, a third shaft body is fixed to one end of the rotating shaft, a rotating air cylinder is fixed to one end of the third shaft body, a limiting mechanism is arranged on the rotating shaft, and the rotating air cylinder is used for controlling the limiting mechanism to expand or contract, so that the limiting mechanism limits the take-up reel; after the take-up reel finishes take-up, the limiting mechanism rapidly expands or contracts through work of the rotary air cylinder, and therefore automatic limiting and releasing of the take-up reel are achieved. By means of the design, manual intervention is remarkably reduced, and production efficiency is improved.
