A positioning fixture block 20133 is further arranged on the left side of the bottom surface of the pressure relief groove 2013, when the rotatable supporting plate 2031 rotates on the left side, the left side of the rotatable supporting plate 2031 can push away the positioning fixture block 20133 from the left side of the positioning fixture block 20133 to move to the right side of the positioning fixture block 20133, so that the positioning fixture block 20133 limits the rotatable supporting plate 2031 at the position, and the rotatable supporting plate 2031 can be kept in an open state.

The relief hole 2014 is shaped as a triangle having a vertex facing the rear side of the rotatable supporting plate 2031. The cross-sectional shape of the silicone plug 2032 is the same as the shape of the pressure relief aperture 2014 to better plug the pressure relief aperture 2014.

The inner side walls of the two bottom corners of the triangle are arc-shaped curved surfaces protruding outwards. The purpose of the arc-shaped curved surface is to realize smooth transition.

The box body 1 is provided with four side edges, the outer side edge of the sealing cover 2 is provided with four lock catch mounting grooves 2012, each lock catch 202 is respectively mounted in each lock catch mounting groove 2012, the two ends of each lock catch mounting groove 2012 are respectively provided with a hinged inserted bar 20121, each lock catch 202 comprises a lock catch body 2021, a hinged groove 2022, a

lock catch edge

2023 and 2 locking units 2024 which can tightly lock the side edge of the box body 1, the hinged groove 2022 is arranged at the top end of the lock catch body 2021, the hinged groove 2022 and the hinged inserted bars 20121 at the two ends of each lock catch mounting groove 2012 are respectively inserted and combined, the hinged groove 2022 and the two hinged inserted bars 20121 can rotate relatively, the lock catch edge 2023 is arranged at the bottom of the inner side wall of the lock catch body 2021. In this embodiment, the latch body 2021, the hinge groove 2022, the

fastening edge

2023, and 2 locking units 2024 are integrally formed.

The locking unit 2024 includes 2 linear curved protrusions 20241 protruding upward, the linear curved protrusions 20241 extend along the longitudinal direction of the fastening edge 2023, and a gap is left between any two adjacent linear curved protrusions 20241.

The number of the locking units 2024 is two, and the two locking units 2024 are respectively disposed at two ends of the buckling edge 2023.
