FIELD OF THE PRESENT INVENTION
The present invention relates to connecting tool, and particular to a more power-saving coaxial terminal connecting tool for various types of coaxial terminals.
DESCRIPTION OF THE PRIOR ART
A prior coaxial terminal connecting tool will need different pressing components while connecting different types of coaxial terminal (such as F type coaxial terminal, BNC coaxial terminal) or coaxial terminal in same type but different specification (such as different lengths). There are coaxial terminal connecting tools capable of replacing various pressing components for different types or specifications of coaxial terminal, but higher cost and storage problem disturb user for preparing various pressing components.
The coaxial terminal tool includes a handle, base, and transmitting unit. The handle is pivoted to an end of the base so that a linking mechanism between the handle, base, and the transmitting unit is formed. In a prior art, in order to apply different types and lengths of coaxial terminal to one tool, an adjusting unit and connecting portion are arranged to the transmitting unit so that a length of the tool can be adjustable. With reference to FIG. 1, a prior coaxial terminal connecting tool 20 is illustrated. A second connecting portion 13 of a transmitting unit 10 pivoted to a handle 50 can be shifted upwards by an adjusting unit 12 of the handle 50. A distance between a pressing component 31 linking to a first connecting portion 14 of the transmitting unit 10 and a terminal fixing unit 60 is thus changed so that the pressing component 31 is capable of connecting different types and lengths of coaxial terminal.
However, the second connecting portion 13 moved by the adjusting unit 12 will also lengthen a distance of the handle 50. Thus, more strength will be needed to operate the tool and more inconveniences are caused to the user and the process.
Therefore, to resolve the problems of the prior art, a more power-saving coaxial terminal connecting tool for various types of coaxial terminal is needed.
