NOVEL TRAMCAR FROG

Disclosed in the present invention is a novel tramcar frog, comprising a frog body, a sliding block, and four grooved steel rails respectively fixed to four ends of the frog body by welding. An assembly cavity is formed in the upper end face of the frog body, and the sliding block is movably and adjustably assembled in the assembly cavity; two sets of symmetrically arranged frog flangeways each in the shape of the Chinese character "八" are formed on the left and right sides of the assembly cavity on the upper end face of the frog body; a first connecting flangeway and a second joint flangeway are formed in the upper end face of the sliding block, and the first connecting flangeway and the second connecting flangeway are in the shape of the Chinese character "八". By adjusting the position of the sliding block, the first connecting flangeway and the second connecting flangeway are communicated with a corresponding pair of obliquely corresponding frog flangeways in the two sets of frog flangeways each in the sha
