The specific embodiment
Connecting rod promotes instrument, comprise moving fulcrum 3, adjustment screw 1, spring 6, co-acting lever and clamp arm 7 on handle 2, the handle, it is characterized in that, co-acting lever is made up of lever arm 4 and hand-held pole 9, lever arm and hand-held pole 9 are fixedly connected into " L shaped ", described moving fulcrum 3 is positioned at the junction of lever arm 4 and hand-held pole 9, adjustment screw 1 is positioned at the moving fulcrum 3 tops side that keeps left, clamp arm 7 is fixedly connected on the other end that handle 2 departs from moving fulcrum 3, is provided with spring 6 between hand-held pole 9 and the handle 2.
Clamping part at clamp arm 7 and lever arm 4 is equipped with fixture block 5, and the bolt locating hole that is connected with connecting rod is arranged on the fixture block 5.
When spring 6 was in relaxed state, lever arm 4 was in open configuration, and when needing the clamping connecting rod, the people holds hand-held pole 9 and handle 2, compression spring 6, and lever arm steps up connecting rod.
In addition, if because after connecting rod lifting instrument steps up, need people's screwing, a people rises and does not sell, and can a locking device be installed at hand-held pole 9 places, and behind hand-to-hand grip holding rod 9, locking device pins hand-held pole 9, artificial then screwing.Unclamp if desired and just open locking device, release.
This connecting rod promotes instrument before use, adjustment screw 1 need be regulated the openings of sizes of lever arm 4, realizes initial work.
