The invention relates to a smashing device for a kitchen. The smashing device comprises a smashing groove and a cover plate which is located at the top end of the smashing groove and matched with the smashing groove, the cover plate is detachably connected with the smashing groove, the interior of the cover plate is of a hollow structure, a smashing hammer is arranged in the smashing groove, a swing rod is fixed to the top end of the smashing hammer, a first arc-shaped block for increasing the working area of the smashing hammer is arranged on one side of the top of the swing rod, a sliding structure matched with the first arc-shaped block and used for driving the swing rod to swing is arranged on one side of the first arc-shaped block and located in the cover plate, the top end of the swing rod extends into the cover plate, a driving structure used for driving the smashing hammer to move up and down and improving the buffering performance of the smashing hammer is arranged in the cover plate, and a scraping plate matched with the smashing groove is arranged on the outer side of the bottom of the swing rod and located above the smashing hammer in a sleeving mode.

The invention discloses a road indicator plate and a mounting method thereof, Including a column, a fixing rod, a fixingring and an end cap, characterized in that: the top end of the upright post is provided with a positioning groove, The fixing rod is vertically arranged in the positioning groove, the fixing ring is arranged on the fixing rod, a sign plate, a limiting groove and a connecting block are arranged on the fixing ring, a clamping groove is arranged on the inner wall of the limiting groove, a clamping block is arranged on the connecting block, and the end cover is provided with a connecting ring and a connecting tooth, and the connecting ring is connected with the fixing rod. The invention is provided with a buffer groove on the fixing ring, which improves the buffer performanceof the fixing ring and strengthens the strength of the fixing ring through the buffer groove. In addition, the connecting block on the adjacent fixing ring is rotated into the buffer groove to facilitate the separation of the clamping block on the connecting block from the clamping groove, thereby facilitating the separation of the upper and lower adjacent two fixing rings.

The invention provides a tire body structure and a non-pneumatic tire. The tire body structure comprises a head part and a neck part, the neck part is arranged on the inner circumferential surface ofthe head part and protrudes towards the radial inner side of the tire, and the inner circumferential surface of the head part, the side surface of the neck part and the inner circumferential surface of the neck part jointly define a matching part matched with a rim; a plurality of radial center holes and a plurality of radial side holes are evenly distributed in the inner circumferential face of the neck part at intervals along the whole circumference of the tire, the radial center holes are located in the axial center of the inner circumferential face of the neck part, and the radial side holes are symmetrically formed in the two sides of the radial center holes and distributed alternately with the radial center holes in the circumferential direction of the tire, the radial center holes and the radial side holes are perpendicular to the inner circumferential face of the neck part and extend towards the radial outer side of the tire; a plurality of axial holes are formed in the side surface of the head part and are communicated with the radial central holes in a one-to-one correspondence manner; the phenomenon of ring slipping between the tire and a rim can be avoided, it is ensured that the tire has good buffer performance and durability, and the endurance mileage of a vehicle is increased.
