The bus pull handle capable of being adjusted in height is composed of transmission devices, a pressure switching device, a fastening device, a time delay device and an automatic band collecting and releasing device. The time delay device is located on the lower side in a handle frame and is used for converting outer force of a passenger into mechanical force. The transmission devices are located on the two sides in the handle frame and are used for transmitting the mechanical force to the pressure switching device. The pressure switching device is located on the upper side in the handle frame and can tightly bite a hanging band after transmission of the mechanical force. The fastening device is located in the middle position on one side in the handle frame and can prevent the clamped hanging band from slipping. One end of the automatic band collecting and releasing device is arranged on a bus, and the other end of the automatic band collecting and releasing device is connected with the right middle of the lower side in the handle frame and is used for adjusting the length of the hanging band.
