[0017] Furthermore, each end of the pancake spreader is provided with a positioning screw hole communicating with the two slots, and a locking screw is threaded into each of the two positioning screw holes.
[0018] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. After the two standard plates are adjusted to the appropriate position, the two locking screws are manually tightened until one end of each screw abuts against the two standard plates to fix them in place. The operation is simple, time-saving and labor-saving.
[0019] Furthermore, the distance between one end of the two standard plates and the pancake spreader is ≤18mm.
[0020] The advantages of adopting the above-mentioned further scheme are that the structure is simple, the spacing between one end of the two standard plates and the spreading rod is reasonably set, and the thickness of the coal sample is guaranteed to be within the standard range.
[0021] Furthermore, the two standard plates are each in the form of a long strip plate structure.
[0022] The advantages of adopting the above-mentioned further scheme are that the structure is simple, the shape of the two standard plates is reasonably designed, and it is easy to adjust in order to prepare coal samples of different thicknesses.
[0023] Furthermore, it also includes a handle, one end of which is connected to the pancake spreader.
[0024] The advantages of adopting the above-mentioned further solution are that the structure is simple, the design is reasonable, and the operator can operate the entire tool by using the handle, which is convenient, time-saving and labor-saving.
[0025] Furthermore, one end of the handle is detachably connected to the pancake spreader, and the angle between the handle and the pancake spreader is in the range of 40-80°.
[0026] The advantages of adopting the above-mentioned further solution are that the structure is simple, the handle and the spreading rod are reasonably distributed, which makes it easy for operators to operate the entire tool with the handle, and the operation is simple, time-saving and labor-saving.
