Abstract
The invention provides a metal hose tension and compression rigidity measuring device. The device comprises a sleeve which is provided with a containing cavity, an abutting pressing device and a transmission device. The containing cavity is used for containing a to-be-tested metal hose. The abutting pressing device is connected with one end of the sleeve and can be driven by external force to get close to or far away from the sleeve, and when the abutting pressing device gets close to or far away from the sleeve, pressure or tension can be applied to the sleeve so that the to-be-tested metal hose in the sleeve can bear pressure or tension. The external force and the abutting pressing device are arranged in a transmission connection mode through the transmission device. The abutting device is driven by the external force to get close to or far away from the sleeve through the transmission device.
