Through the protruding cooperation of spacing recess and spacing card, one forms spacingly to the mounted position of connecting block, and two come, through reasonable size design, when spacing protruding complete cooperation embedding of card was installed in spacing recess, first mounting hole and screw hole just aim at, aim at to position between them and play the guide effect.

The upper end face of the limiting clamping protrusion is flush with the upper end face of the connecting block. The whole structure is neat and compact.

The lateral part of connecting block outside arch be provided with many elastic positioning muscle, many the elastic positioning muscle parallel from top to bottom and interval set up, elastic positioning muscle with the inner wall of cavity hug closely. The tight fit of connecting block in the cavity is realized to inlay through the protruding muscle of elastic positioning and is established the installation, reduces the manufacturing accuracy requirement to the connecting block, effective reduction in production cost.

The table foot installation position be set up on the crossbeam with the shape matched with of table foot installation sunken, the table foot inlay establish install corresponding position the installation sunken in. The whole structure is neat and compact.

The connecting block is made of PE plastic.

Compared with the prior art, the utility model has the advantages that: through the connecting block of establishing a threaded hole in close-fitting inlays in the table foot, during the integral erection, only need with the connecting block from the open-top of cavity beat in the installation table foot, make the threaded hole align with first mounting hole position can, simple structure, easily installation, assembly efficiency is high, and ordinary consumer also can accomplish the installation by oneself, has reduced manufacturing cost effectively.
