Description

Technical Field

[0001] The utility model relates to the technical field of parallel groove wire clamps, and specifically relates to a copper-aluminum composite special-shaped parallel groove wire clamp. Background Art

[0002] The copper-aluminum composite special-shaped parallel groove wire clamp is a special electrical device, mainly used to connect copper wires and aluminum wires. The special feature is the design of its shape and structure, which enables it to adapt to different environments and application requirements.

[0003] Copper-aluminum composite special-shaped parallel groove wire clamps have the characteristics of long service life and firm connection, so they have been widely used. When operators use special-shaped parallel groove wire clamps, they usually work at heights. The existing special-shaped parallel groove wire clamps have a simple structure, which causes the bolts to fall off easily after being inserted into the clamp block without installing the nuts. Since the operators work at heights, the missing parts will prevent the work from proceeding smoothly, which greatly affects the work efficiency, so it needs to be improved. Utility Model Content

The operator can pull the handle 11 downward so that the handle 11 drives the support plate 10 out of contact with the bolt body 3.

[0034] Among them, the elastic mechanism includes:

[0035] A cylinder 12, the inner surface of the cylinder 12 is movably sleeved with the outer surface of the round rod 9;

At this time, the operator can release the handle 11, and the first spring 13 will pull the cylinder 12 upward under the action of elastic recovery, so that the cylinder 12 drives the round rod 9 to rotate upward with the round axis 7 as the axis, and then the top of the support plate 10 contacts the bottom of the bolt body 3, so as to support the bolt body 3 and prevent the bolt body 3 from falling off from the inside of the lower clamping block 1, which is convenient for the operator to use.
