Description

Technical Field

[0001] The utility model relates to the technical field of detonators, in particular to a portable detonator pliers. Background Art

[0002] Detonators are the main explosive materials for blasting projects. Their function is to generate detonation energy to detonate various explosives, detonating cords, and detonators. Detonators are divided into fire detonators and electric detonators. Electric detonators are used in underground coal mine detonation. Electric detonators are also divided into instantaneous electric detonators and delayed electric detonators, and delayed electric detonators are divided into second-delay electric detonators and millisecond-delay electric detonators. Detonator pliers (detonator clips) are needed in the production process of detonators. Among all the explosives used in modern industry, only black powder is directly detonated by sparks or flames, and the detonation of other explosives requires detonators. When inserting the fuse into the detonator, a detonator clip is needed (the concept of detonator clips: when using the ignition and blasting method, a fire detonator, that is, a detonator connected to the fuse, should be made; if a detonator with a metal shell is used in the blasting work, the fuse can be fixed in the shell with a detonator clip); the detonation of the detonator can be caused by sparks or flames, or by the explosion of other detonators. Therefore, there are three methods of detonating explosive charges: open flame, electricity, and detonating cord.

[0003] At present, in order to make the detonator pliers anti-slip during use and avoid accidental slipping and falling during use, most of the detonator pliers are usually covered with rubber sleeves, plastic sleeves or some anti-slip patterns on the pliers handles to achieve anti-slip effect. However, this method still causes the pliers to slip accidentally, and most of the existing detonator pliers lack anti-slip structures, making them inconvenient to use and relatively poor in practicality.
