Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1-3, the tool bar assembly of the present invention is a tool bar assembly of a pull type hand tool, and will be described in detail below with reference to a high branch shear as an example.
The pull type hand tool rod body combination comprises a pull rope 4, a tool rod 6, a pulley component 5 and a sliding sleeve 7. The pull rope 4 is connected with the movable part of the tool head, and after the pull rope is pulled, the movable part of the tool head is pulled to move. Stay cord 4 is connected with pulley assembly 5, and the movable suit of sliding sleeve 7 is on instrument pole 6, and the lower extreme and the sliding sleeve 7 rigid coupling of stay cord still include connecting rod 3. The upper end of the connecting rod 3 is connected with the lower end of the tool head, preferably fixedly connected into a whole. The lower end of the connecting rod 3 is connected with a tool bar 6. The connecting rod is one of a rectangular pipe or a circular pipe, and the tool rod is a telescopic rod.
As a preferred technical scheme: pulley assembly 5 is disposed inside the connecting rod. The pull ropes comprise an upper pull rope 4-1 and a lower pull rope 4-2; the lower end of the upper section pull rope 4-1 and the upper end of the lower section pull rope are respectively connected with the pulley component.
