Tensile strength testing device for automotive plastic accessory

The utility model discloses a tensile strength testing device for a vehicle plastic accessory. The tensile strength testing device comprises a tester main body, a lifting sliding table, a lower clamping seat, an upper clamping seat, a sensor, a secondary reinforcing mechanism and a protective device, the secondary reinforcing mechanism is arranged on the inner side of the lower clamping seat, the connecting frame drives the long nail to move by screwing the second screw rod, and the long nail can penetrate through the static clamping piece and the movable clamping piece through the first through hole and the second through hole respectively, so that a sample is nailed between the movable clamping piece and the static clamping piece, further reinforcing can be carried out, and the sample clamping efficiency is improved. By arranging a protection device at the bottom of the lifting sliding table, when the sample is in a stretching state in the testing process, the stored deformation energy of the sample is larg
