[0003] When the existing tamping machine is in use, it is necessary to use a hammer rod to impact the ground to achieve the tamping effect. When the hammer rod is working, it will generate a reverse force opposite to the running direction of the hammer rod. Under the combined effect of the reverse force and the driving force of the tamping machine, the hammer rod is subjected to a large impact force, which causes the hammer rod to shake and deviate during operation, resulting in a problem of shortening the service life of the hammer rod.
