Preferably, described nut assembly comprises the nut that is threaded onto on the described screw mandrel and two clamping plate that are used for the described nut of clamping position, and 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 that pushes against for pushing against workpiece that pushes against sheet is a cambered surface.
Preferably, the described face that pushes 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.
Beneficial effect of the present invention is: 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 is so that structure is more stable, save and wait for clamping time, easy and simple to handle, the face that pushes against that pushes against head can be the various form that is complementary with the workpiece wall, and practicality is wider.
