Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings.

With reference to fig. 1-3, the locking mechanism with the boosting function comprises a connecting rod 1, a guide rail 2, a sliding rod 3, a handle 8 and a base 7, wherein the handle 8 comprises a lock cap 9, a shifting block 10, a bolt 12, a lock hook 13 and a pushing spring 14, the sliding rod 3 comprises a pressing piece 4, a cover plate 5 and a cushion plate 6, the handle 8 and the base 7 are riveted through the bolt 11 to form a revolute pair, the pushing spring 14 is pressed into the lock cap 9 by the lock hook 13 to be pushed to a certain position, the shifting block 10 is embedded into the lock hook 13 through a waist-shaped hole at the upper end face of the lock cap 9 and riveted through the bolt 12, the pushing spring 14 is always kept in a compressed state, the pressing piece 4 is arranged in a semicircular guide groove of the sliding rod 3 and is fastened by the cover plate 5 with a semicircular guide groove, the pressing piece can freely rotate along the circular guide groove formed by matching and pressing, the cushion plate 6 is fixed on the large face of the pressing piece, the handle 8 is connected with the slide bar 3 by the connecting rod 1 and the guide fastener 15.
