A pair of outward extending clamp arms are arranged on the periphery face of the seal cover, and the seal headis provided with a lock cylinder hole penetrating through the two ends of the seal head. The lock head and the lock cylinder hole are in one-way inserting and connecting fit. One ends of the pull wires are connected with the corresponding clamp arms, and the other ends of the pull wires penetrate through corresponding channels located in the corresponding seal pins to be connected with the lock head. The provided safety lead seal is reliable in usage, the opening process is convenient, and component scattering is avoided after opening.

Description

technical field [0001] The invention relates to a lead seal, in particular to a safety lead seal. Background technique [0002] A lead seal is a lock-like device applied by a specific person after the item is packed and the door is properly closed. Once the lead seal is properly locked, it cannot be opened unless it is violently damaged, and the damaged lead seal cannot be reused. As long as the appearance of the box is complete, the door of the box is properly closed, and the seal with the corresponding lead seal is properly locked, it can prove that the box has not been opened without permission. For example, the electric meter used in each of our families in daily life is used to prevent some users who want to steal electricity from modifying the electric meter privately. A lead sealing wire is used to fasten the two box doors of the electric box, and then the lead sealing wire is used. Both ends pass through a lead seal block made of lead hot melt; for example, some sp...
