The invention is described in detail below with reference to the drawings and the specific embodiments.

Example 1

A microscope, a stage 1 is provided on top of a base 2 via a lifting column.

The limiting device consists of an L-shaped trigger 3 and an alarm circuit. The alarm circuit consists of an end part of an L-shaped trigger 3, a limiting block, a power supply 8 and an audible and visual alarm 7 which are sequentially connected in series through a lead 6.

As shown in fig. 1, the limiting blocks are 2, namely a first limiting block 4 and a second limiting block 5, and are fixedly arranged on the side surface of the base 2 along the height direction. The L-shaped trigger 3 is suspended at the bottom of the objective table 1, and the end part of the L-shaped trigger 3 is arranged between the first limiting block 4 and the second limiting block 5.

The audible and visual alarm 7 comprises a warning lamp and a buzzer and is also arranged on the side surface of the base 2.

In the use process, the water-soluble fiber is prepared,

When the lifting column moves upwards, the objective table 1 is linked with the L-shaped trigger 3 upwards, the end part of the L-shaped trigger 3 contacts the first limiting block 4, the alarm circuit is conducted, the audible and visual alarm 7 is electrified, and audible and visual alarm is sent out.

When the lifting column moves downwards, the objective table 1 is linked with the L-shaped trigger 3 downwards, so that the end part of the L-shaped trigger 3 contacts the second limiting block 5, the alarm circuit is conducted, the audible and visual alarm 7 is electrified, and audible and visual alarm is sent out.

Example 2

Based on the structure of embodiment 1, the stopper is movably disposed on the side surface of the base 2 through the reset device.
