One large glitch was detected in PSR B1737$-$30 using data spanning from MJD57999 to 58406 obtained with the newly built Shanghai Tian Ma Radio Telescope(TMRT). The glitch took place at the time around MJD 58232.4 when the pulsarunderwent an increase in the rotation frequency of $\Delta \nu$ about1.38$\times 10^{-6}$ Hz, corresponding to a fractional step change of $\Delta\nu / \nu$ $\thicksim$ 8.39$\times 10^{-7}$. Post$\textrm{-}$glitch $\nu$gradually decreased to the pre$\textrm{-}$glitch value. The frequencyderivative was observed to undergo a step change of about $-$9$\times 10^{-16}$s$^{-2}$. Since July 1987, there are 36 glitches already reported in PSRB1737$-$30 including this one. According to our analysis, the glitch sizedistribution is well described by the power law with index of 1.13. Thedistribution of the interval between two adjacent glitches (waiting time$\Delta T$) follows a Poissonian probability density function. For PSRB1737$-$30, the interval is prone to be long after a large glitch. But nocorrelation is found between glitch size and the interval since previousglitch.
