The utility model discloses high elastic double density shoe sole relates to the field of sole production, including sole main part, the sole main part, the first bonding groove corresponding with the sole bottom of the sole main part top outer wall is seted up, the inside of sole main part is equipped with the elastic structure for reinforcing the elasticity of sole, the elastic structure includes the first elastic buffer chamber and second elastic buffer chamber of setting up in the inside of sole main part, and the first elastic buffer chamber and second elastic buffer chamber inner wall are equipped with elastic buffer block, the sole main part bottom is equipped with the antiskid structure. This high elastic double density shoe sole has greatly strengthened the elasticity of sole, in the walking or movement process, the reaction force of ground is absorbed and dispersed by the synergistic effect of elastic buffer chamber, elastic buffer block and silica gel, can efficiently buffer ground reaction force, effectively reduces the impact to foot and joint, reduces the risk of sports injury, provides excellent comfortable experience for the user.

This utility model relates to the technical field of bag sealing and cutting equipment, and proposes a simple tape sealing machine suitable for supermarket and retail packing tables. The sealing machine consists of paired support plates forming a through-rotation groove at their upper ends. Rotatably mounted support components include a round shaft and a radial extension to support the tape roll. A vertical groove at the front end of the support plate serves as a restricted channel for feeding and cutting. On both sides of the channel are arranged a one-way ratchet stepping mechanism consisting of toothed pins / moving teeth and toothed wheels, and an embedded cutting mechanism consisting of a rocker arm blade holder, a pointed blade, and a return spring. A tailing bar with an arc-shaped protrusion and an auxiliary spring are provided on the other side of the blade holder to achieve overshoot assistance and anti-rebound. Optionally, a safety blade holder can be provided on the outside of the support plate for trimming / emergency cutting, and anti-slip rubber feet can be provided at the bottom to improve table stability.
