The specific embodiment
Combine accompanying drawing that the utility model is done further explain through the specific embodiment below.
As depicted in figs. 1 and 2; A kind of screw rod tightening tool sketch map for the utility model; This screw rod tightening tool comprises rotary drive and screw sleeve 6, and rotary drive comprises support tube 9, rotating shaft, elastic strip 2 and rope band 4, and rotating shaft is installed in the support tube 9 and with support tube 9 and forms revolute pair; Its upper end is connected with support tube 9 tops through elastic strip 2, and the lower end is connected with screw sleeve 6; The barrel of support tube 9 is provided with opening, and rope band 4 one ends are fixed and are wrapped on the rotating shaft, and the other end passes opening and stretches out outside the support tube 9; Screw sleeve 6 one ends have and are used for fixing the connecting portion that connects rotating shaft, and the other end has the location division of matching with screw head.
The rotating shaft lower end can be fixedly connected with screw sleeve 6, also can removably connect through certain mode and screw sleeve 6, so that use different screw sleeves 6 according to the different size replacement of screw rod.In a kind of mode that removably connects; The end that rotating shaft is used for fixing connecting screw rod sleeve 6 is provided with banking pin; Connecting portion on the screw sleeve is the stopper slot that matees with banking pin; Banking pin can snap in screw sleeve 6 and rotating shaft are together rotated, and the location division of screw sleeve 6 is a groove, and the head of screw rod can snap in screw sleeve 6 drive screw rods are together rotated and tensioning threaded rods.
Preferably, rotating shaft comprises bearing 8 and central shaft 5, and bearing 8 outer rings are fixed on the inwall of support tube 9; Inner ring fixed center axis 5; Because the existence of bearing 8, the frictional force during the central shaft rotation reduces greatly, and then its frictional dissipation is obviously reduced; The upper end of central shaft 5 is connected with support tube 9 tops through elastic strip 2, and the lower end is fixedly connected with screw sleeve 6.
In the present embodiment, the top in the support tube 9 is provided with cross bar 1, and elastic strip 2 is fixed on the cross bar 1, and central shaft 5 upper ends are provided with crotch 3, and elastic strip 2 one ends hang on the crotch 3, and the other end hangs on the cross bar 1, and this structure is convenient to install elastic strip more.
