[0043] Example 2

[0044] Reference Figure 1 , Figure 2 ,as well as Fig. 9 - Fig.11 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the device can be folded for easy storage and carrying.

[0045] Compared with Example 1, further, the movable component 500 includes a first rotating block 501 arranged on the second movable rod 400, a second rotating block 502 rotatably arranged on both sides of the first rotating block 501, and a control member 503 arranged on the first rotating block 501 and the second rotating block 502, which is used to adjust the relative state of the first rotating block 501 and the second rotating block 502.

[0046] The control member 503 includes a handle 503a disposed on one side of one group of second rotating blocks 502, which is used to pull the limiting block 503b, and a limiting block 503b disposed on the handle 503a. The limiting block 503b is in sliding contact with the second rotating block 502. The limiting block 503b is a rectangular column, which plays a role of limiting sliding. The first bevel gear 503c disposed on the limiting block 503b is used to cooperate with the first gear groove 503d to fix the position of the second rotating block 502. The first bevel gear 503c gradually decreases from the side close to the limiting block 503b to the outside. The longest diameter of the cross section of the first bevel gear 503c is not greater than the minimum side length of the cross section of the limiting block 503b. The first gear groove 503d of the first bevel gear 503c and the first connecting shaft 503e arranged on one side of the first bevel gear 503c play a connecting role. The diameter of the first connecting shaft 503e is not larger than the minimum diameter of the cross section of the first bevel gear 503c. The first connecting shaft 503e is in sliding contact with the first rotating block 501 and the second rotating block 502. The abutment piece 503f arranged at the rear end of the first connecting shaft 503e is used to cooperate with the outer wall of the second rotating block 502. The second return spring 503g is compressed by the movement of the first connecting shaft 503e. The second return spring 503g arranged between the abutment piece 503f and the second rotating block 502 is used to drive the first connecting shaft 503e to return to its original position.

[0047] During use, when the device needs to be unfolded or folded, or the observation position of the observation assembly 100 needs to be adjusted, the handle 503a is pulled to disengage the limiting block 503b from the clamping connection with the second rotating block 502, and the first bevel gear 503c leaves the first gear slot 503d, and the first connecting shaft 503e drives the contact piece 503f to squeeze the second return spring 503g, and the first rotating block 501 and the second rotating block 502 can rotate freely. When adjusted to the required position, the handle 503a is released, and the second return spring 503g is restored, driving the first connecting shaft 503e, the first bevel gear 503c, and the limiting block 503b to pull back, and the first bevel gear 503c is meshed with the first gear slot 503d again, and the limiting block 503b re-enters the second rotating block 502, and the relative position of the first rotating block 501 and the second rotating block 502 is fixed again, and the above steps can be adjusted again.

[0048] The remaining structures are the same as those of Example 1.

[0049] Example 3

[0050] Reference Figure 1 , Figure 2 ,as well as Fig.12 - Fig.14, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that it enables the device to be stably placed on a variety of surfaces.

[0051] Compared with Example 2, further, the placement component 600 includes a base plate 601 arranged below the second movable rod 400 through the movable component 500, which is used to place the observation sample and play a supporting role at the same time; an empty groove 602 opened at the lower part of the base plate 601 is used to store the insertion rod 603; the insertion rod 603 arranged in the empty groove 602 is used to unfold and insert into the ground when the ground is uneven to fix the device; the thickness of the insertion rod 603 does not exceed the depth of the empty groove 602, which is convenient for completely storing the insertion rod 603 to avoid affecting the stability of the device when it is placed on the ground; the rotating rod 604 arranged between the insertion rods 603 is used to cooperate with the adjusting member 605 to drive the rotation of the insertion rod 603; and the adjusting member 605 arranged in the base plate 601 is used to adjust the rotation of the rotating rod 604.

[0052] The adjusting member 605 includes a second connecting shaft 605a disposed in the bottom plate 601, a second bevel gear 605b disposed at both ends of the second connecting shaft 605a for transmission, a third bevel gear 605c disposed at one end of the rotating rod 604 and meshingly connected with the second bevel gear 605b, a third connecting shaft 605d disposed at one side of the second bevel gear 605b for connecting with a gear shaft 605e, and a gear shaft 605e disposed at the other end of the third connecting shaft 605d for cooperating with a third bevel gear 605c to drive the rotating rod 604 to rotate. The adjusting screw 605f, which rotates in conjunction with the rotation of the adjusting screw 605f and is arranged in the base plate 601 and meshingly connected with the gear shaft 605e, is used to drive the gear shaft 605e to rotate, and at the same time cooperates with the gear shaft 605e to form a self-locking function to prevent the insertion rod 603 from being unfolded due to gravity and retracted when inserted into the ground, causing inconvenience in using the device; and the turning handle 605g arranged at one end of the adjusting screw 605f is used to control the rotation of the adjusting screw 605f. One end of the adjusting screw 605f connected to the turning handle 605g is movable and passes through the outer wall of the base plate 601.

[0053] During use, if the ground of the natural environment is flat, the device can be directly unfolded and the bottom plate 601 can be placed directly on the ground. When the ground of the natural environment is uneven and the device cannot be placed stably, the handle 605g is turned to drive the gear shaft 605e to rotate by adjusting the screw 605f. At this time, the second bevel gear 605b drives the third bevel gear 605c to rotate. At this time, the rotating rod 604 rotates to drive the insertion rod 603 to unfold from the empty slot 602. The handle 605g is turned until the insertion rod 603 is unfolded in place. At this time, the insertion rod 603 is inserted into the ground until the bottom plate 601 contacts the ground. At this time, the device is fixed on the ground. When the observation is over, the insertion rod 603 is pulled out of the ground and the insertion rod 603 is cleaned. At this time, the handle 605g is rotated in the opposite direction to completely retract the insertion rod 603 into the empty slot 602.

[0054] The remaining structure is the same as that of Example 2.
