A kind of plug-type fast assembling and disassembling device of extensometer of this utility model, mainly by metal J-shaped clamping limb, spring, iron wire,
Metal plate is constituted.The metal J-shaped clamping limb of two symmetrical shapes is made, its straight section root is provided with screwed hole, will by bolt
On two screwed holes of the right and left that two metal J-shaped clamping limbs are separately fixed at extensometer knife edge piece；The one of two identical springs
End is separately fixed on the tiny column of metal J-shaped clamping limb stage casing protrusion, and the other end is connected on iron wire, forms v shape structures,
Make two spring angles adjustable between 100 ° -110 °；Iron wire one end connecting spring, the other end are connected to the screw of metal plate
On, the distance at two ends is suitably adjusted, and allows spring to be constantly in extended state, so that two metal J-shaped clamping limbs are initially in
Close strong state；Iron wire two ends distance, and then the elongation of change spring just can be changed by the length for changing iron wire winding,
So as to the size of adjustable clamp holding force when needed.
Metal J-shaped clamping limb one end constrains in and rotates secondary, and passes through spring in the middle part of metal J-shaped clamping limb
It is connected on iron wire, clamps which by spring power；Iron wire is S-shaped, one end connecting spring, and the other end is connected spiral shell
Nail.Two end of S-shaped iron wire winds indentation, and then adjustment length to S stage casings；Make arc-shaped, clamping in metal J-shaped clamping limb one end
Directly push in during test specimen, pull straight out during dismounting extensometer, realize the rapid-assembling/disassembling of extensometer.
Advantage of the present utility model and beneficial effect：1st, realize clamping device integrated with general extensometer, and fill
With convenient；2nd, the connection of extensometer and test specimen is capable of achieving with singlehanded push-and-pull and separate, it is efficient and convenient；3rd, relatively conventional rubber
Muscle fixed form ensure that safety and reliability.The quick of extensometer, safety assembly and disassembly and reliability can be realized in actual applications
Connection.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the plug-type fast assembling and disassembling device of a kind of extensometer of this utility model, mainly by gold
Category J-shaped clamping limb 1, spring 2, iron wire 4, metal plate 3 are constituted.The metal J-shaped clamping limb 1 of two symmetrical shapes is made, which is straight
Section root is provided with screwed hole；Two metal J-shaped clamping limbs 1 are separately fixed at by bolt for the right and left of extensometer knife edge piece 5
Two screwed holes on；One end of two identical springs 2 is separately fixed on the tiny column of 1 stage casing of metal J-shaped clamping limb protrusion,
The other end is connected on iron wire 4, forms v shape structures, makes two springs, 2 angle adjustable between 100 ° -110 °；4 one end of iron wire connects
Spring 2 is connect, the other end is connected on the screw of metal plate 3, and the distance at two ends is suitably adjusted, allow spring 2 to be constantly in stretching
State, so that two metal J-shaped clamping limbs 1 are initially in the strong state of closure；Just may be used by the length for changing the winding of iron wire 4
Change 4 two ends distance of iron wire, and then change the elongation of spring 2, so as to the size of adjustable clamp holding force when needed.
1 one end of metal J-shaped clamping limb constrains in and rotates secondary, and passes through bullet in the middle part of metal J-shaped clamping limb 1
