The base plate 11 is provided with two rails 1a, the rails 1a are arranged in parallel, the number of screw holes 1b is four, and each two screw holes 1b are respectively arranged on each support plate 12 in a group.
The clamping member 2 is matched with the shape of the sample 5 for clamping the sample 5. The clamping piece 2 is detachably connected with the first driving mechanism 3 and the second driving mechanism 4 respectively. The clamping members 2, the first driving mechanism 3 and the second driving mechanism 4 each have four, and each clamping member 2 is driven by the respective first driving mechanism 3 and second driving mechanism 4.
As shown in fig. 2, the first driving mechanism 3 includes a moving block 31 and a driving member including a screw 32, a snap-in connector 33, and a shutter 34. Wherein, the moving block 31 is arranged above the clamping piece 2 and connected with the clamping piece 2, the screw rod 32 passes through the screw hole 1b and can move back and forth in the screw hole 1b, the clamping joint 33 is arranged at the end part of the screw rod 32, the baffle 34 is provided with a through hole 341, and the clamping joint 33 passes through the through hole 341 and is connected with the moving block 31. In this way, the screw 32 rotates in the screw hole 1b to move back and forth, but due to the baffle 34, the clamping head 33 can only drive the moving block 31 to move without driving the moving block 31 to rotate, so as to drive the clamping piece 2 to move.
As shown in fig. 3, the second driving mechanism 4 includes a bolt 41 and a nut 42, the nut 42 is movably provided on the rail 1a, the bolt 41 passes through the rail 1a, one end of the bolt 41 is screwed with the nut 42, and the other end passes through the moving block 31 into the holder 2 to be connected with the holder 2. Each track 1a is provided with two second drive mechanisms 4. The clamping piece 2 can rotate at any angle only by loosening the nut 42, then the nut 42 is screwed, and the corresponding clamping piece 2 is kept fixed at the angle, so that the clamping piece 2 can change any angle.
In this way, the first driving mechanism 3 can drive the holder 2 to move in the direction of the rail 1a, thereby clamping the sample 5. The second driving mechanism 4 can drive the holder 2 to rotate and can maintain the rotated state of the holder 2.
In this embodiment, the sample is a rectangular parallelepiped, and the holder 2 is also a rectangular parallelepiped. The working principle of the embodiment is that the sample 5 to be measured is placed on a horizontal table surface downwards, then the direct-reading spectrometer sample clamp is placed above the sample 5, the screw 32 is rotated, and the angle of the clamping piece 2 is adjusted, so that the sample 5 is fixed. As shown in fig. 4, in a state where the holder 2 grips the sample 5, the holder 2 abuts against at least part of the outer periphery of the sample 5. And then placing the clamped sample 5 on an excitation table for excitation, so as to obtain the chemical components of the sample. If the surface to be measured of the sample 5 is larger than the excitation hole, the sample 5 can directly cover the excitation hole, otherwise, the clamping piece 2 and the sample 5 cover the excitation hole together, so that the excitation hole is effectively covered.
Example two
The present embodiment differs from the first embodiment in that the sample 5 is a cylinder and the holder 2 is also a cylinder. In a state where the holder 2 grips the sample 5, the holder 2 abuts at least part of the outer periphery of the sample 5, as shown in fig. 5.
The clamping member 2 in the first embodiment can be directly detached and then the clamping member 2 in the present embodiment can be mounted. Of course, the clamping element 2 can also be provided integrally with other adjacently connected components.
