Example 2:
as shown in fig. 7, different from embodiment 1, vent holes 14 are formed in the upper and lower sides of the L-shaped vertical plate 111 corresponding to the groove 112, a check valve 15 is disposed in the corresponding vent hole 14, a sealing piston 16 is fixedly connected to one end of the extension rod 113 located in the insertion slot, a sound tube 17 communicated with the upper vent hole 14 is fixedly connected to the upper end of the L-shaped vertical plate 111, and a plurality of reeds 18 are fixedly connected to the interior of the sound tube 17.
After the detection mark is finished, the pushing spring 115 pushes back the supporting plate 114, so that the sealing piston 16 at the rear end of the extension rod 113 moves outwards relative to the groove 112 to suck air, the air enters from the vent hole 14 at the position corresponding to the sound tube 17 on the upper side, and then the reeds 18 in the sound tube 17 vibrate to sound, so as to prompt a worker to finish the detection in time.
