Body is connected with the bottom of right lever, and the bottom of described movable cramping body is provided with gripper shoe, described activity
The thickness of cramping body and fixed clamp body is respectively smaller than the gap between concrete core sample and concrete foundation.
Described fixed clamp body is an arc body, and the inwall of arc body is fitted with concrete core sample outer wall.
Described attachment means include connecting plate, connecting stud and tightening nut, and described connecting plate is arranged on a left side
The bottom of lever, connecting plate is provided with a through hole, and connecting stud is arranged on the top of movable cramping body, institute
The connecting stud stated passes through the through hole of connecting plate, and is fastened by tightening nut, the top of described connecting stud
It is provided with push rod, described push rod is consistent with the gripper shoe direction of Activity supporting body bottom.
Described movable cramping body is a cylinder.
The end of described left lever and right lever is respectively arranged with curved portions.
Fixed by welding manner phase between described fixed clamp body and right lever.
Compared to the prior art the sampler for concrete core sample of the present invention, has beneficial effect following outstanding：Can
Easily to take out concrete core sample, concrete core sample will not be damaged, the complete of concrete core sample will not be destroyed
Property, do not interfere with follow-up detection or monitoring, concrete core sample is during taking out it is not necessary to manually go to connect
Tactile concrete core sample extracts, and improves work efficiency；The bottom of movable cramping body is provided with gripper shoe, Ke Yiqi
To the purpose supporting concrete core sample, prevent concrete core sample from dropping；In fixed clamp body, wall is arc, permissible
So that fixed clamp body is fitted close with concrete core sample outer wall, increase contact area, make concrete core sample light
The features such as loose ground takes out.

Specific embodiment
The sampler for concrete core sample of the present invention is described in detail below to accompanying drawing 3 with reference to Figure of description 1.
The sampler for concrete core sample of the present invention, its structure includes left lever 1, right lever 2, rotating shaft 3 and folder
Hold mechanism 4, between the described right lever 2 of left lever 1, pass through connected, the described clamping machine of rotating shaft 3
Structure 4 is arranged on the bottom of left lever 1 and right lever 2, and described clamping device 4 includes movable cramping body
