[0027] A first cross bar 300 connecting the upper ends of the first connecting rod 210 and the second connecting rod 220;
[0028] A second cross bar 400 connecting the middle parts of the first connecting rod 210 and the second connecting rod 220, the first cross bar 300 and the second cross bar 400 being parallel to each other.
[0029] Please refer to Figure 2 When in use, the sleeve 100 is tilted. One end on the upper side and the other end on the lower side of the inner wall of the sleeve 100 are in contact with the core sample 500, and the core sample 500 is clamped, so that the core sample 500 can be extracted. When it is necessary to release the core sample 500, the sleeve 100 is placed upright, and the sleeve 100 can be naturally taken out from above the core sample 500. The operation is fast, convenient and safe. And the first cross bar 300 and the second cross bar 400 are provided. When it is necessary to tilt the sleeve 100, the first cross bar 300 can be held by hand, and the second cross bar 400 can be supported by the arm to be tilted to form a lever, which is convenient to use, has stable force and high safety.
[0030] Preferably, the first connecting rod 210 and the second connecting rod 220 are symmetrically arranged. The symmetrical arrangement has stable and balanced force.
[0031] Please refer to Figure 1 The first connecting rod 210 and the second connecting rod 220 extend axially. Alternatively, the first connecting rod 210 and the second connecting rod 220 can also be inclined inward as needed to form an isosceles trapezoid with the first cross bar 300.
[0032] Preferably, the lower end surface of the sleeve 100 has a chamfer. It is convenient for the sleeve 100 to extend in.
[0033] Particularly, connection holes are provided on the first connecting rod 210 and the second connecting rod 220, and the first cross bar 300 and the second cross bar 400 are inserted into the corresponding connection holes. The connection holes are provided to improve the stability of the first cross bar 300 and the second cross bar 400. The first cross bar 300 and the second cross bar 400 can be screwed, bolted or welded after passing through the connection holes.
[0034] Particularly, the first cross bar 300 is welded to the connecting rod, and the second cross bar 400 is welded to the connecting rod.
[0035] Preferably, as another embodiment of the present invention, the second cross bar 400 is detachably connected to the connecting rod.
