The invention discloses a tool for rapid press fitting of a planetary shaft. The tool comprises a hydraulic machine and a workbench top and further comprises a support connected to the workbench top, a pressing plate connected to the top of the support, and a fastener. One end of the fastener penetrates the pressing plate, and the fastener is connected with the pressing plate. A gap is formed between the bottom of the fastener and the upper large circle end face of a planet carrier, and it can be ensured that the upper large circle end face of the planet carrier is moved into the position below the fastener through the gap. When the fastener inclines on the planet carrier, the fastener abuts against the upper large circle end face, the inclination degree of the planet carrier is limited, and it is ensured that the planetary shaft is pressed in a planet hole. According to the tool, assembly of the planet carrier can become easy and fast, and therefore the labor intensity of workers is lowered, and the production efficiency is improved.

The invention relates to a punching tool. A conventional punching tool such as a box nailing machine which is rotatingly provided with a limiting part adjacent to a shooting outlet for limiting the position or inclination of a punched article is capable of punching a thin nail with a relatively small head part from the center of the shooting outlet in a straight way. However, the conventional punching tool which is limiting the rotation direction of the limiting part is unable to fully perform position or inclination limitation. Therefore, defective punching is especially to be decreased. The invention aims to reduce defective punching by more reliably limiting the position or inclination of punched articles. Specifically, the aim is achieved through the following ways of limiting the inclination of punched articles (n) in the front-back direction through a first limiting part (10) rotatingly supported by an actuator guide part (4); equipping a circular-ring shaped second limiting part (20) on an orifice adapter (30) equipped on a contact rod (9); and limiting the position or inclination of the punched articles (n) circumferentially through the second limiting part (20).
