Shield tail sealing brush tensile test equipment and test method thereof

The invention relates to the technical field of tensile test equipment, and discloses shield tail sealing brush tensile test equipment and a test method thereof.The shield tail sealing brush tensile test equipment comprises a supporting unit, a pull-up detection unit, a locking limiting unit and a clamping unit. According to the shield tail sealing brush clamping device, by arranging the clamping unit, an operator can rotate a worm to drive a worm gear and a lead screw shaft to rotate, a lead screw lantern ring on the lead screw shaft moves synchronously, a guide plate at the bottom is driven to move downwards, and finally a connecting support and a clamping plate can be driven to press downwards to clamp the whole shield tail sealing brush; the grinding rollers at the bottom synchronously extrude and clamp the shield tail sealing brush shell, when the clamping unit clamps the shield tail sealing brush shell unfirmly, in a tensile test, the clamping unit integrally moves and drives the grinding rollers to rot
