The positioning pins 18 are preferably provided in plural numbers, and more preferably, are arranged near each corner of the angle adjusting plate 13.

Alternatively, the level adjustment plate 12 and the angle adjustment plate 13 are the same in size, for example, both are rectangular plates and have the same length and width dimensions.

The first rotating shaft 151 is preferably located in the middle of the level adjusting plate 12, and in a structure in which the level adjusting plate 12 is a rectangular plate, for example, the first rotating shaft 151 passes through the center of the plate surface of the level adjusting plate 12. The first rotating shaft 151 is also preferably connected to a middle portion of the angle adjusting plate 13, and in a structure in which the angle adjusting plate 13 is a rectangular plate, for example, the first rotating shaft 151 passes through a center of a plate surface of the angle adjusting plate 13.

Further, the locking bolt 16 is preferably provided in plurality, and the threaded locking hole is correspondingly provided in plurality, so as to ensure stability and reliability of the locking structure of the angle adjusting plate 13.

As can be understood, since the locking bolt 16 needs to pass through the angle adjustment plate 13 and then be screwed into the corresponding threaded locking hole, a bolt through hole is correspondingly formed on the angle adjustment plate 13. Since the angle adjusting plate 13 tends to rotate relative to the level adjusting plate 12, the bolt passing hole may be an arc hole coaxial with the first rotating shaft 151 in order to ensure that the locking bolt 16 can be screwed with the threaded locking hole of the level adjusting plate 12 all the time.

In one embodiment, as shown in fig. 1, 2 and 4, the leveling assembly includes an adjusting screw 172, the adjusting screw 172 passes through the adjusting base 11 from bottom to top and abuts against the leveling plate 12. It can be understood that the adjusting base 11 is correspondingly provided with a threaded hole, and is in threaded connection with the adjusting screw 172, and the adjusting screw 172 is guaranteed to make vertical linear motion through the limitation of the threaded hole, so as to achieve the purpose of adjusting the vertical position of the leveling plate 12 at the corresponding position.
