Embodiment
For features described above and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below.
As shown in Figure 1 and 2, a kind of liquid relief frame, including scissors double leval jib lifting structure 1, the scissors double leval jib lifting structure
1 two upper ends are respectively articulated with the clamping jaw 3 to holding test tubes 2, and the clamping jaw 3 includes external clip 31, the external clip 31
Inside is hinged with internal clip 32 and lower internal clip 33, the external clip 31 and upper internal clip 32, the pin joint of lower internal clip 33
Place is provided with the torsion spring 34 for keeping upper internal clip 32 to be opened with lower internal clip 33；Under the two of the scissors double leval jib lifting structure 1
End has been respectively articulated with feed screw nut 4, and two feed screw nuts 4 are threaded on screw mandrel 5 respectively, and the screw mandrel 5 is laterally set
Put on base 6, the chute 7 that the base 6 offers to be slidably matched with two feed screw nuts 4 along its length, institute
State the screw thread at the both ends of screw mandrel 5 on the contrary, the screw mandrel 5 with to drive its rotate micromachine 7 be connected, the micromachine
7 be clockwise and anticlockwise motor, and the screw mandrel 5, feed screw nut 4, chute 7, micromachine 7 form screw mandrel slide unit structure.
In the utility model embodiment, the external clip 31, upper internal clip 32 and lower internal clip 33 are curved.
