Preferably, the first described clamping piece uses cyclic structure, and the second described clamping piece uses cover body structure.
It is further preferred that it is provided with observation circular hole on the second clamping piece of described cover body structure.
It is further preferred that the outside of the first clamping piece of described cyclic structure uses cone structure.
Preferably, described main body cylinder uses two round petals bodies, including left semicircle arc valve body and right semi-circle arc valve body,
The both sides of left semicircle arc valve body are provided with indent stage portion, and right semi-circle arc valve body both sides, which are provided with, can be embedded in left semicircle arc valve
The protrusion stage portion of the indent stage portion of body.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
1) the utility model is a kind of deformation coal sampling equipment, and it is simple and easy to do to adopt deformation coal.Examination prepared by the utility model
Sample is tested, the characteristic of former deformation coal can be more really disclosed by testing obtained deformation coal characterisitic parameter.
2) the cylindrical test sample for meeting the requirement of deformation coal attribute testing can be prepared by this method.
3) equipment easy processing, cost is cheap, and can be recycled.
4) test specimen being prepared into using the utility model can more embody structure compared with the test specimen of existing moulded coal
Make the various genuine properties of coal.
5) the utility model patent can eliminate the disturbance damage for preparing that cutting belt is come during sample, protect to greatest extent
Stay the primary structure of deformation coal.
