Fig. 1 is the structural representation of utility model works state.
Fig. 2 is the sectional view of A-A part in Fig. 1.
Fig. 3 is that this utility model leaves unused the structural representation of device.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1,2 and 3, this utility model comprises lead screw gear and clamping device.
Described lead screw gear comprises base plate 1, two-way leading screw 3 and feed screw nut 2.Described base plate 1 is provided with a rectangular recess, the wall of base plate 1 groove one end is provided with a through hole, one end of described two-way leading screw 3 and the wall of base plate 1 groove one end are for being rotatably connected, the other end is connected with a crank 4 through the through hole in base plate 1 groove walls, the thread rotary orientation at two-way leading screw 3 two ends is contrary, match with a feed screw nut 2 respectively in the two ends of two-way leading screw 3, when rotating two-way leading screw 3, two feed screw nuts 2 can move toward one another.
Described clamping device is two covers, often cover comprises fixing head 6, clamping plate 8 and top board 7, described fixing head 6 is fixedly connected with feed screw nut 2 by connecting rod 5, the lower surface of described fixing head 6 and the upper surface of base plate 1 fit, when rotating two-way leading screw 3, because the lower surface of fixing head 6 and the upper surface of base plate 1 fit, can play guide effect, feed screw nut 2 drives fixing head 6 along base plate 1 concave slot sports.
The other end of described fixing head 6 and one end of clamping plate 8 are by hinge, and on described bearing pin, cover has a torsion spring 10, and the arm angle in a free state at described torsion spring 10 two ends is 90 °, and the arm at the two ends of torsion spring 10 is against on fixing head 6 and clamping plate 8 respectively.One end and the clamping plate 8 of described top board 7 are hinged by stud shaft, and top board 7 can rotate on clamping plate 8 around stud shaft, and described top board 7 is in L-type.When using this utility model, pull clamping plate 8, make the torsion of clamping plate 8 antagonism torsion spring 10 and fixing head 6 be in same plane, rotating top plate 7 then, makes one end of top board 7 be against on fixing head 6, this makes it possible to make clamping plate 8 and fixing head 6 in the same plane.
In prioritization scheme, one end of described top board 7 is provided with a through hole, and the through hole of the lower end of top board is passed in one end of push rod, and the other end of push rod is fixedly connected with one end of knob, is connected between described knob with top board 7 by extension spring.During use, pull knob, enable top board 7 one end with push rod rotate to one end of fixing head 6, unclamp knob, push rod is withstood on fixing head 6 by the pulling force of extension spring, this makes it possible to fixing head 6 and clamping plate 8 are fixed at grade.
