Preferably, a power storage spring is arranged at the bottom of each limiting clamping plate. The effect of holding power spring is the spacing cardboard of being convenient for reset, because the effect clamping plate of ratchet can't inwards reset, and holds power spring's effect and be supplementary spacing cardboard compression, spacing cardboard is to compressing in the compression groove that resets and extending plate break away from, and the clamping plate will reset under elastomeric element's effect.

Preferably, the number of the limiting clamping plates is 6, and the number of the clamping plates is 6. The number of the limiting clamping plates corresponds to the number of the clamping plates, the number of the clamping plates can be increased or decreased according to the requirements, the utility model uses 6 limiting clamping plates and 6 clamping plates as an example for explanation, and the 6 limiting clamping plates and the 6 clamping plates are symmetrically arranged and correspond to each other one by one.

Preferably, the elastic component is a shrapnel or a spring. The elastic part is used for assisting the clamping plates to move inwards or inwards in two sides in the sleeve holes, and the elastic sheet or the spring can achieve the effect.

Thus, a universal socket of the present utility model adapted for mounting screws of different sizes has the following advantages: the clamping plate and the positioning protrusion in the sleeve can clamp the bolts, so that the bolts or the bolts can be effectively prevented from slipping in the sleeve holes, the limiting clamping plate in the sleeve holes is matched with the clamping plate to clamp and fix the bolts, the resetting can be realized by only pressing an external wedge plate after the screwing is finished, the operation is simple and convenient, a plurality of sleeves are not required to be carried during the use, and the working efficiency is increased.
