The invention discloses a steel-plastic composition corner brace for an aluminum alloy door / window. The steel-plastic composition corner brace comprises an outer layer plastic main body and an interior metal framework, wherein the outer layer plastic main body coats the interior metal framework, multiple reinforcing locating holes are formed in the interior metal framework, framework grooves are formed in the outer side of the interior metal framework, framework protruded blocks are arranged on the inner side of the interior metal framework, the framework grooves are located in outer side grooves of the outer layer plastic main body, and the framework protruded blocks are located at inner side protruded blocks of the outer layer plastic main body. Compared with the prior art, the steel-plastic composition corner brace for the aluminum alloy door / window has the advantages that an improved interior metal framework is mainly utilized, so that the framework grooves of the interior metal framework can directly contact with aluminum alloy, and meanwhile, the framework protruded blocks can bear the pressure of an aluminum alloy frame on the inner side, so that the grooves and the protruded blocks on the two sides are matched to further reinforce the aluminum alloy door / window, and the aluminum alloy door / window is firmer and prevents from cracking and removing; and the service life is prolonged, the maintenance rate is reduced, and popularization and application values are achieved.

The invention discloses a mechanical pile-clamping case, and relates to a main component of a static pile press. The mechanical pile-clamping case comprises a pile-clamping case main body the upper end of which is connected with a main press cylinder, a round wokpiece pile hole is formed at the center of the pile-clamping case main body, two pairs of movable integrated jaws which are connected with the main press cylinder are arranged in the pile-clamping case main body symmetrically, and movable blocks are arranged on the movable integrated jaws, one end of each movable block is in rotary connection with one movable integrated jaw, and the other end of each movable block is provided with a spring. The mechanical pile-clamping case provided by the invention has the advantages of simple manufacture process, low cost, stable performance, convenience in maintenance, long service life, and low cost which is reduced by 40% as compared with that of the traditional pile-clamping case, completely eliminates the problems of pile breakage and slippage, has low maintenance probability, has prolonged service life, is in no need of jaw replacement when applied to piles in various specifications, and is simple and convenient to operate, and the jaw service life is also prolonged.

The present disclosure relates to a gripping arm (2) suitable for a device (1) for gripping, holding and guiding, in particular bottle-shaped containers, wherein the device has a control device (11) to move the gripping arm ( 2) the gripping section (5) moves from the extended position to the gripping position or from the gripping position to the extended position, the gripping arm comprises a bore (10) for supporting the bearing pin (20), to pivotally fix the grab arm (2) in the device (1) and include a force accumulator for moving the grab segment (5) of the grab arm (2) from the grab position to The unfolded position or move from the unfolded position to the grab position. In order to achieve the goal of such a gripping arm which remains sufficiently free of dirt and germs, can thus be cleaned without problems and can be produced quickly and easily, it is provided that the force store has an integral design Elastically deflectable spring tongues ( 6 ) on the gripping arm ( 2 ) are in or come into active engagement with spring tongues of the mirror-symmetrically designed gripping arms ( 3 ) of the device ( 1 ).
