The utility model is optimized for further: described latch-up structure comprises the compact heap being located at the relative T-slot side of T-shaped slide block, described compact heap is connected with T-shaped slide block slip and the glide direction of glide direction and T-shaped slide block is perpendicular, makes the compression of compact heap and T-shaped chute or loosen by the governor motion be arranged on clamp.

By adopting technique scheme, compact heap can be realized by governor motion and sliding along the direction perpendicular with T-shaped slide block glide direction, thus realize the compression of compact heap and T-shaped chute or loosen, realizing the lock function between clamp and upper shell.

The utility model is optimized for further: described governor motion comprises the adjusting screw(rod) be threaded with clamp, and one end and the compact heap activity of described adjusting screw(rod) are connected, and the other end passes clamp and is provided with rotation holding head.

By adopting technique scheme, being arranged on the rotation holding head of adjusting screw(rod) one end by rotating, realizing the slip that adjusting screw(rod) drives the relative T-shaped slide block of compact heap, and then the compression realized between compact heap and T-shaped chute and the effect loosened.

The utility model is optimized for further: described compact heap is provided with unidirectional tooth relative to the one side of T-slot, and described T-slot is provided with the unidirectional card article matched with unidirectional tooth relative to the one side of compact heap.

By adopting technique scheme, can first drive compact heap and T-shaped chute compress with adjusting screw(rod), slide clamp subsequently again, by the cooperation of unidirectional tooth and unidirectional card article, just firmly can clamp after clamp clamping insulating barrier, operate flexibly convenient.

Compared with prior art, the utility model has following advantage: can directly be inserted by insulating barrier by the fixing cell body be arranged on lower house, then by being arranged on the movable cell body on upper shell, by clamp, insulating barrier is further clamped, make the state of insulating barrier on housing more firm, decrease the probability occurring to get loose with housing.
