When the other person needs to disassemble the case band 500, the second lead sealing assembly must be broken, so that the bolt 600 is disassembled, and the case band 500 is disassembled.
The third abutting portion 315 and the fourth abutting portion 316 position the plug 600 along the circumferential direction of the ferrule 300, so that the fifth connection hole 541 is aligned with the sixth positioning hole 631.
In some embodiments, the side portion of the plug 600 has a protruding arc portion 620, and the arc portion 620 is disposed towards the body 110, so that when the plug 600 slides through the first plug hole 521 and the second plug hole 317, the arc portion 620 has a guiding function, so as to correct the position of the plug 600, and then quickly slides into the first plug hole 521 and the second plug hole 317.
In some embodiments, the side of the latch 600 has a boss 610, and the boss 610 is disposed toward the body 110, such that the boss 610 abuts against a side of the third abutment 315 away from the body 110, thereby preventing the latch 600 from sliding away from the lower port of the second observation hole 510. Meanwhile, the boss 610 is in abutting connection with the third abutting portion 315, thereby achieving positioning of the plug 600 in the axial direction, and further aligning the fifth connection hole 541 with the sixth positioning hole 631.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention. Furthermore, embodiments of the invention and features of the embodiments may be combined with each other without conflict.
