The invention provides a plug bush which is firmly contacted with pins of a power plug, has large contact area and great current capacity and is used for domestic use, etc. An upper end of a slot wallof a U-shaped slot plug bush is sequentially extended and bent towards the inside of the plug bush to form an elastic contact piece, an elastic support piece, a support arm, an auxiliary supporting piece and an inclined support arm. When the plug bush is completely tabled with the pin, the support arm, the auxiliary support piece and the inclined support arm to form a firm A-frame which is supported among slot walls to push the pin to have close surface contact with the plug bush, that is, a firm maximized permanent clamping force is formed, and the clamping force is never weakened or lost, and the serious dependence of the clamping force of the plug bush on property, thickness and elasticity of a sheet metal is overcome. The plug bush with the shape and the structure has the advantages of large current capacity, safe use and long service life.

The invention discloses a concrete compaction anti-cracking agent which comprises 20.0-60.0% of light calcined magnesia, 10.0-30.0% of calcium oxide-calcium sulfoaluminate double-expansion source expanded clinker, 5.0-15.0% of gypsum and 20.0-50.0% of a fine powder material of which the specific surface area is greater than 300m<2> / kg, wherein the sum of the contents of all components is 100% based on the total mass of the concrete compaction anti-cracking agent. The concrete compaction anti-cracking agent can be used in concrete to effectively inhibit shrinkage of the concrete and improve the compactness and the durability of the concrete.
