[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A field tree measuring device comprises a ruler body 1, two groups of connecting sleeves 2 are arranged on the outer side of the ruler body 1, and first measuring plates 3 are respectively distributed at the front ends of the two groups of connecting sleeves 2, one group of connecting sleeves 2 is fixedly connected to the ruler body 1, and the other group of connecting sleeves 2 is slidably connected to the ruler body 1, so that when measuring, the connecting sleeves 2 slidably connected to the ruler body 1 can be pushed to a suitable position for measurement, a rectangular groove is opened inside the first measuring plate 3, and a second measuring plate 4 is inserted inside the rectangular groove, a T-shaped bar 5 is connected to the side of the second measuring plate 4, and a slideway matched with the T-shaped bar 5 is opened inside the first measuring plate 3.

[0023] Further, see Figure 2 and Figure 3 It can be known that the top of the first measuring plate 3 is connected to a support frame 6, and an insertion rod 7 is vertically inserted inside the support frame 6, and a pull ring 8 is connected to the upper side of the insertion rod 7, and the lower side of the insertion rod 7 passes through the inner wall of the first measuring plate 3 and extends into the second measuring plate 4, and the interior of the second measuring plate 4 is evenly distributed with limiting grooves that are compatible with the insertion rod 7. When in use, the second measuring plate 4 pulled to a suitable position can be limited by the mutual cooperation of the insertion rod 7 and the limiting groove, thereby effectively preventing the second measuring plate 4 from being easily displaced during the measurement process.

[0024] Further, see Figure 3 It can be known that a movable plate 9 is sleeved on the outer side of the insertion rod 7, and the outer wall of the movable plate 9 abuts against the inner wall of the support frame 6. The movable plate 9 abutting against the inner wall of the support frame 6 can effectively ensure the stability of the insertion rod 7 during the up and down movement.

[0025] Further, see Figure 3 It can be known that a spring 10 is vertically connected to the upper side of the movable plate 9, and the other end of the spring 10 is connected to the inner wall of the support frame 6. The spring 10 is sleeved on the outside of the insertion rod 7. The spring 10 connected above the movable plate 9 can effectively ensure the tightness of the insertion rod 7 when it is engaged in the limiting groove of the second measuring plate 4.

[0026] Further, see Figure 4 It can be known that a slot hole 11 is provided inside the connecting sleeve 2, and the inner wall of the slot hole 11 is connected to a rotating rod 12 through a bearing. The first measuring plate 3 is sleeved on the outer side of the rotating rod 12. When in use, the first measuring plate 3 and the rotating rod 12 are fixedly connected. Since the rotating rod 12 is connected to the inner wall of the slot hole 11 through the bearing, the first measuring plate 3 can be pushed to rotate ninety degrees and then stored.

[0027] Further, see Figure 4 It can be known that the top end of the rotating rod 12 extends to the top of the connecting sleeve 2 and is sleeved with a connecting ring 13, and the side of the connecting ring 13 is connected to a connecting plate 14, and the lower side of the connecting plate 14 is vertically connected to a positioning rod 15, and the interior of the connecting sleeve 2 is provided with a slot adapted to the positioning rod 15, and the inner side of the connecting ring 13 is connected to a slider, and the interior of the rotating rod 12 is provided with a slide groove adapted to the slider. Through the mutual cooperation of the slider and the slide groove, the connecting ring 13 can be rotated with the rotating rod 12, and through the mutual cooperation of the connecting plate 14 and the positioning rod 15, the rotating rod 12 can be limited after rotation, so as to effectively prevent the first measuring plate 3 from sliding easily during carrying.

[0028] Further, see Figure 4 It can be known that there are two groups of connecting plates 14, and the two groups of connecting plates 14 are symmetrically distributed about the central axis of the connecting ring 13. Through the arrangement of the two groups of connecting plates 14 and the positioning rod 15, the limiting effect of the rotating rod 12 can be effectively improved. Four groups of slots are opened inside the connecting sleeve 2, so as to achieve the fixation of the positioning rod 15 after rotation.

[0029] Working principle: When the utility model is used, the staff can hold the ruler body 1 and place the two sets of first measuring plates 3 between the trees, and then slide the connecting sleeve 2 on the right side to make the two sets of first measuring plates 3 fit the trees, so as to complete the measurement of the tree diameter. When the measured tree is thicker, the staff can pull the pull ring 8 in turn to drive the insertion rod 7 to be pulled out from the inside of the second measuring plate 4, and then the staff can push the second measuring plate 4 to slide it inside the first measuring plate 3, so that the combined length of the first measuring plate 3 and the second measuring plate 4 changes. When the combined length of the two is adjusted to a suitable length, the staff can stop pulling. Pull ring 8, so that the insertion rod 7 can be inserted into the corresponding limiting groove inside the second measuring plate 4 to limit the second measuring plate 4. After use, the staff can manually pull up the connecting plate 14, so that the positioning rod 15 connected to its lower side is pulled out from the inside of the connecting sleeve 2, and then the staff can rotate the first measuring plate 3, so that the rotating rod 12 can rotate at the same time. When the first measuring plate 3 and the rotating rod 12 are rotated ninety degrees, the staff can push down the connecting plate 14, so that the positioning rod 15 is engaged with the other two groups of slots to limit the first measuring plate 3, thereby realizing the storage of two groups of first measuring plates 3. The above is the entire working principle of the utility model.
