Preferably, described nut assembly comprises the nut that is threaded onto on the described screw mandrel and is used for two clamping plate that described nut is located in clamping that two described clamping plate are fixed on the described installing plate.
Preferably, described lead is fixed on the described base plate by the mount pad at two ends.
Preferably, described push against the head comprise by securing member be installed in the support on the described leading truck, the flexibility that is installed on the described support pushes against sheet.
Preferably, the described face of pushing against for pushing against workpiece that pushes against sheet is a cambered surface.
Preferably, the described face of pushing against for pushing against workpiece that pushes against sheet is two coaxial cambered surfaces.
Preferably, described leading truck is U-shaped, and it is enclosed within respectively on a pair of described guide pillar slidably with both sides.
Preferably, described installing plate parallels with described base plate.
The beneficial effects of the utility model are: adopt feed screw nut and cylinder two-stage can realize the mechanism of stretching, enlarged the scalable scope that pushes against head, the size range of the workpiece that can use is wider, the telescoping mechanism of two-stage: one-level adopts feed screw nut, another level to adopt cylinder, and the deficiency of cancelling out each other makes structure more stable, save and wait for clamping time, easy and simple to handle, the face of pushing against that pushes against head can be the various form that is complementary with the workpiece wall, and practicality is wider.
