In order to ensure that the clamping effect of the clamping blocks on the exhaust pipe of the bulb is achieved without damaging the exhaust pipe of the bulb, the clamping blocks are made of rubber, and the number of the clamping blocks is at least two and are symmetrically arranged in the radial direction of the exhaust pipe.
Further, the reset piece is a magnetic block, and magnetism of the magnetic block positioned on the opposite side of the clamping block is the same. When the clamping blocks are not subjected to extrusion force of the side wall of the valve body along the radial direction of the supporting rod, the clamping blocks can be separated under the action of the magnetic blocks with the same magnetism, and the test of the next bulb is not affected.
Further, the shape of the upper end face of the sealing piston is matched with the top inner wall of the valve body. Under the condition that the shape of the upper end face of the sealing piston is matched with the top inner wall of the valve body, the sealing effect of the bulb pressure-resistant detection device is best.
