Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, this preferred embodiment provides a kind of clamping device, including shell 4 and lower clamping jaw 8, shell
The top surface at 4 middle part is equipped with groove 3, and lower clamping jaw 8 is set in groove 3, and the bottom of shell 4 offers the spiral shell of communication groove 3
Pit, the interior matching of threaded hole are provided with drive screw 1, the bottom of clamping jaw 8 under the top alignment of drive screw 1, are equipped in shell 4
Two guide rods 2 moving up and down being laterally arranged, two guide rods 2 are pierced by the fixed company of opening of the shell in 3 side of groove
The two sides of lower clamping jaw 8 are connected to, the every upward side of guide rod 2 is equipped with vertically arranged active block 6 moving up and down, main
Motion block 6 is set in shell 4, and the top of active block 6 is the high rake one in 3 side of groove low close to 3 side of groove, separate
61, the top of each active block 6 is equipped with the passive grip block 5 that can be moved left and right, and passive 5 one end of grip block is to be fitted in inclination
Rake 2 51 in portion 1, the other end are directed toward groove 3, and shell 4 is provided with connection in passive 5 place horizontal position of grip block
