Technical Field

[0001] This utility model relates to the field of plant measurement technology, and more specifically, to a diameter measuring instrument. Background Technology

[0002] In botanical research and agricultural production, accurate measurement of plant diameter is an important task. Plant diameter not only reflects its growth status but is also closely related to its biomass, stress resistance, and yield.

[0003] Traditional diameter measurement methods often rely on manual tools, such as measuring tapes or traditional vernier calipers. These tools typically only allow for single-dimensional measurements, requiring frequent adjustments to position and pressure, making them unsuitable for measuring branches and stems in different locations and shapes of plants. The process is cumbersome and inefficient. To address these issues, this device was invented. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diameter measuring instrument, including a main scale and a vernier scale, with a longitudinal measuring sleeve fixedly installed on both the main scale and the vernier scale. Multiple snap-fit ​​holes are equally spaced on the longitudinal measuring sleeve. A longitudinal measuring claw is slidably connected to the longitudinal measuring sleeve, and a snap-fit ​​component is provided on the longitudinal measuring claw. A transverse measuring sleeve is located below the longitudinal measuring claw. A one-way screw is rotatably installed on the transverse measuring sleeve, and a handwheel is fixedly installed at the outer end of the one-way screw. A transverse measuring claw is threadedly connected to the one-way screw, and the width of the transverse measuring claw is equal to the width of the transverse measuring sleeve.

[0007] Furthermore, the diameter of the snap-fit ​​hole is equal to the diameter of the snap-fit ​​block.

[0008] Furthermore, the longitudinal measuring claw and the transverse measuring sleeve are set vertically.

[0009] Furthermore, a plug-in block is fixedly installed at the bottom of the longitudinal measuring claw, and a plug-in groove adapted to the plug-in block is opened at the top of the transverse measuring sleeve.

[0010] Furthermore, a first bolt hole is provided on the plug block, and a second bolt hole with the same diameter as the first bolt hole is provided on the plug groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the longitudinal measuring claw is connected to the longitudinal measuring sleeve via a snap-fit ​​assembly. The operator can easily adjust the length of the longitudinal measuring claw extending out of the longitudinal measuring sleeve according to actual needs. The transverse measuring claw is connected to the transverse measuring sleeve via a one-way screw.

[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example:

[0022] See attached document Figures 1-3 This embodiment provides a diameter measuring instrument for measuring the diameter of plants. It includes a main scale 1 and a vernier scale 2. Both the main scale 1 and the vernier scale 2 are fixedly mounted with longitudinal measuring sleeves 3. Multiple locking holes 4 are evenly spaced on the longitudinal measuring sleeves 3. A longitudinal measuring claw 5 is slidably connected to the longitudinal measuring sleeve 3. A locking assembly 6 is provided on the longitudinal measuring claw 5. The locking assembly 6 includes a connecting spring 601. An installation hole is provided on the longitudinal measuring claw 5. The connecting spring 601 is fixedly installed in the installation hole. A locking block 602 is slidably connected in the installation hole, and the locking block 602 is fixedly connected to the connecting spring 601. Furthermore, the diameter of the locking hole 4 is equal to the diameter of the locking block 602.

[0023] During use, the operator adjusts the length of the longitudinal measuring claw 5 extending out of the longitudinal measuring sleeve 3 according to actual needs. During this process, the operator presses the locking block 602, causing the locking block 602 to retract into the mounting hole. At this time, the connecting spring 601 is in a compressed state. Then, the operator pulls the longitudinal measuring claw 5 until the locking block 602 on the longitudinal measuring claw 5 corresponds to the locking hole 4 in the appropriate position, thereby achieving the purpose of adjusting the overall length between the longitudinal measuring sleeve 3 and the longitudinal measuring claw 5.

[0024] See attached document Figure 2 A transverse measuring sleeve 7 is provided below the longitudinal measuring claw 5. The longitudinal measuring claw 5 and the transverse measuring sleeve 7 are vertically arranged. Specifically, a plug-in block 11 is fixedly installed at the bottom of the longitudinal measuring claw 5. A plug-in groove 12 adapted to the plug-in block 11 is opened at the top of the transverse measuring sleeve 7. A first bolt hole 13 is opened on the plug-in block 11. A second bolt hole 14 with the same diameter as the first bolt hole 13 is opened on the plug-in groove 12. During assembly, the plug-in block 11 at the bottom of the longitudinal measuring claw 5 is aligned with the plug-in groove 12 at the top of the transverse measuring sleeve 7 and inserted. When the first bolt hole 13 and the second bolt hole 14 are arranged on the same axis, the bolt is inserted into the first bolt hole 13 and the second bolt hole 14 to realize the assembly between the longitudinal measuring claw 5 and the transverse measuring sleeve 7.

[0025] See attached document Figure 1 and Figure 2A one-way screw 8 is rotatably mounted on the transverse measuring sleeve 7. A handwheel 9 is fixedly mounted on the outer end of the one-way screw 8. When in use, rotating the handwheel 9 will rotate the one-way screw 8. A transverse measuring claw 10 is threadedly connected to the one-way screw 8, and the width of the transverse measuring claw 10 is equal to the width of the inside of the transverse measuring sleeve 7, thereby limiting the transverse measuring claw 10. This allows the transverse measuring claw 10 to move along the transverse measuring sleeve 7 during the rotation of the one-way screw 8, thereby adjusting the overall length of the transverse measuring sleeve 7 and the transverse measuring claw 10.

[0026] It should be noted that the longitudinal measuring sleeve 3, longitudinal measuring claw 5, transverse measuring sleeve 7 and transverse measuring claw 10 described in this embodiment are all made of polyethylene material to avoid damaging the outer skin of the plant when measuring the diameter of the plant.

[0027] This diameter measuring instrument measures the plant diameter by adjusting the positions of the longitudinal measuring claw 5 and the transverse measuring claw 10. The longitudinal measuring claw 5 is connected to the longitudinal measuring sleeve 3 via the snap-fit ​​assembly 6, while the transverse measuring claw 10 is connected to the transverse measuring sleeve 7 via the one-way screw 8. Both can be adjusted in length according to measurement requirements to ensure measurement accuracy.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
