As an embodiment of the present invention, referring to fig. 5, the triggering mechanism includes a photovoltaic panel 17, the photovoltaic panel 17 is fixedly connected to one side of the base 11, a slot 18 is formed in the base 11, an iron core 19 is fixedly connected in the slot 18, a coil 20 is wound on the iron core 19, the coil 20 is electrically connected with the photovoltaic panel 17, two magnets 21 are slidably connected in the slot 18, one sides of the two magnets 21 are fixedly connected with a second spring 22, one end of the second spring 22 is connected with a side wall of the slot 18, and two square hooks 23 are rotatably connected in the slot 18.
After sunlight irradiates the photovoltaic panel 17, the coil 20 connected with the photovoltaic panel 17 is electrified, the iron core 19 wound by the coil 20 generates magnetism, the two magnets 21 are pushed to move to two sides by the magnetic force of the coil 20, the magnets 21 can strike against the square hooks 23 and rotate the square hooks 23, the hooks 32 on the baffle 29 are forced to separate from the square hooks 23, then the third springs 26 start to act, when a sun protection mechanism is not needed, the first connecting plate 25 is pressed, the first connecting plate 25 moves downwards along the limiting rod 24 and turns the baffle 29 inwards, the hooks 32 are hung on the square hooks 23, and the sun protection mechanism can automatically act when sunlight exists, so that the convenience of the device is improved.
As an embodiment of the present invention, referring to fig. 1, the sun protection mechanisms are symmetrically disposed on both sides of the level 12, and the trigger mechanism is disposed in the middle of the sun protection mechanism.
The sun protection mechanisms arranged on the two sides can better play a role in sun protection, the level 12 cannot be shielded, the level 12 can work normally under the premise of being subjected to the sun protection effect, and the triggering mechanism can effectively enable the sun protection mechanism to work.
Working principle: after the user places and levels the supporting leg 2 and the leveling instrument 12, the leveling instrument 12 is directly lifted upwards, the first sleeve 4 connected with the bottom of the base 11 moves upwards, the elastic clamping block 9 slides in the clamping groove 5 and is clamped in the clamping groove 5 until the leveling instrument 12 is adjusted to be at a proper height, the user stops lifting, after the use is finished, the connecting block 10 is pressed downwards, the second sleeve 8 drives the elastic clamping block 9 to move towards the inside of the first sleeve 4, the elastic clamping block 9 leaves the clamping groove 5, at the moment, the leveling instrument 12 is pressed downwards, the leveling instrument 12 can be returned to the original position, the user can lift the leveling instrument 12 to a required height after the supporting leg 2 is placed, the user does not need to bend to survey and draw, and the use comfort of the user is improved.
When the sunlight irradiates the level 12, the triggering mechanism is triggered by the sunlight, so that the sun shading mechanism acts, and then sun shading effect is generated on the level 12, so that the damage of the sunlight to the level 12 is reduced, and unnecessary manpower is avoided.
The electric elements are all connected with an external main controller and 220V mains supply through a transformer, and the main controller can be conventional known equipment for controlling a computer and the like.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
