However, if the time is long, the insulating tape may age, and the glue on the tape may also crack. If there is no timely maintenance, the metal part of the wire end may still be exposed, resulting in dangerous accidents.
In addition, since the insulating tape used during operation is generally of the same color, it is difficult to identify different wire ends. In the follow-up work, additional identification of wire ends is required, which increases the workload.

Embodiment Construction
[0010] The invention discloses a safety wire clip, such as figure 1 and figure 2 As shown, it includes a hollow shell, which is longitudinally divided into two halves 1 and 2, and the two half shells are connected by a folded part 3 on the side, so that the two half shells can be folded and opened longitudinally. / closed, the cavity 4 in the housing is coaxial with the safety wire clamp, one end of the cavity 4 is provided with an opening 5 on the housing, and an inward transverse protrusion 6 is provided in the middle of the cavity 4 , the space of the cavity 7 around the protrusion 6 is larger than that of other parts.
[0011] In practice, the safety wire clamp can be opened, and then the exposed metal ends of the wires are wound around the outside of the transverse protrusion 6, so as to be accommodated in the cavity space 7 outside the transverse protrusion 6 and covered with an insulating skin. The part of the wire can pass through the cavity 4 and the opening 5, and ...

The invention discloses a safety wire protection clamp comprising a hollow shell, wherein the hollow shell is longitudinally divided into two halves which are connected through a turnover part at the side part so as to be opened and closed along the longitudinal direction, the cavity in the shell is coaxial with the safety wire protection clamp, one end of the cavity is provided with an opening on the shell, an inward transverse bulge is arranged at the middle part of the cavity, and the space in the cavity around the bulge is larger than that of other parts. The invention adopting the technical scheme has simple structure and low cost, can be used for effectively wrapping up a tip of a lead, and prevents electric shock or short-circuit accident.
Description
technical field [0001] The invention relates to a tool for electricians, in particular to a tool for insulating wire ends. Background technique [0002] Nowadays, in electrical work, it is often encountered that unused wire ends need to be left floating. Some of these wire ends are not charged, but some are charged. If such wire ends are left unattended without treatment, it will cause operators to get an electric shock, or short-circuit the wires or even cause vicious accidents such as fires. In the prior art, the processing method of these wire ends is generally to use insulating tape to wrap the wire ends, so that the metal parts of the wire ends will not be exposed, thereby preventing electric shock or short circuit. However, if the time is long, the insulating tape may age, and the glue on the tape may also crack. If there is no timely maintenance, the metal part of the wire end may still be exposed, resulting in dangerous accidents. In addition, since the insulating...
