When encountering relatively flat ground, the fixing bolts can be pulled out from the fixing holes, and then the collar can be rotated until the roller connected to the bottom connecting column of the collar contacts the ground.

[0004] To address the issue of portability of existing measuring instruments, which are generally quite heavy, forestry workers face significant physical challenges when carrying boxes over long distances. Existing measuring equipment can be dangerous, potentially causing injury to the workers and damage to the equipment. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing measuring equipment, which is generally very heavy. Forestry workers carrying boxes for long distances are physically exhausted, which is dangerous in the forest. This could not only cause personal injury to the forestry workers but also damage the measuring equipment. Therefore, a portable forestry measuring device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a portable forestry measuring device, comprising a measuring instrument body, a support, and a moving component. The support is fixedly connected to the lower surface of the measuring instrument body. A rotating block is provided on the measuring instrument body, and the rotating block is rotatably connected to the surface of the measuring instrument body. A moving component is provided on the surface of the rotating block, and the moving component includes a wheel. The wheel is fixedly connected to the surface of the rotating block, and a fixed block is rotatably connected to the surface of the measuring instrument body. The fixed block is located on the outside of the rotating block.

[0007] Furthermore, the number of rotating blocks is two sets and they are arranged symmetrically. A spring is fixedly connected to the inner wall of the fixed block, and a slider is fixedly connected to the surface of the spring. The slider is slidably connected to the inner wall of the fixed block.

[0008] Furthermore, the surface of the fixed block is provided with a sliding groove, the surface of the slider is fixedly connected with a toggle block, the surface of the slider is fixedly connected with an insertion rod, and the insertion rod is slidably connected to the inner wall of the sliding groove.

[0009] Furthermore, a rod is fixedly connected to the surface of the slider, and a positioning groove is formed on the surface of the rotating block, with the rod inserted into and connected to the inner wall of the positioning groove.

[0010] Furthermore, the surface of the measuring instrument body is provided with an adjustment component, the adjustment component includes a first fixing plate, the first fixing plate is fixedly connected to the surface of the measuring instrument body, the upper surface of the first fixing plate is fixedly connected with a sleeve rod, the number of the sleeve rods is two sets, and the surface of the measuring instrument body is fixedly connected with a second fixing plate, the second fixing plate is located above the first fixing plate.

[0011] Furthermore, an extension rod is slidably connected to the inner wall of the sleeve rod, the extension rod is inserted into the inner wall of the second fixing plate, and a pull rod is fixedly connected to the upper surface of the extension rod.

[0012] Furthermore, the inner wall of the second fixing plate is slidably connected with a fixing post. There are two sets of fixing posts arranged symmetrically. A pull block is fixedly connected to the surface of the fixing post. The pull block is located on the outer side of the second fixing plate. A spring is fixedly connected to the surface of the fixing post. The surface of the extension rod is provided with fixing holes. There are multiple sets of fixing holes arranged in an array. The fixing post is inserted into the inner wall of the fixing hole.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a movable component, the use of wheels is more convenient when moving the main body of the measuring instrument. Pulling the lever causes the adjusting rod to leave the inner wall of the positioning groove, causing the spring to stretch and expand. The wheel then rotates stably along the axis of the rotating block until it reaches the ground. Once the wheel position is adjusted, releasing the lever allows the spring's rebound force to insert the rod into the inner wall of the positioning groove, fixing the rotating block and thus securing the wheel. By setting the movable component, the main body of the measuring instrument can be moved easily, avoiding the problems associated with heavy existing measuring equipment. Forestry workers carrying heavy boxes on long journeys face significant physical challenges, and if they become exhausted, it can be dangerous in the forest, potentially causing injury or damage to the measuring equipment. This effectively improves the convenience of the equipment.

[0015] 2. In this utility model, by setting an adjustment component, the use of the wheels is more convenient when pulling the main body of the measuring instrument. To this end, the two sets of pull blocks are pulled by hand, causing the second spring to compress and the two sets of fixing posts to simultaneously leave the inner wall of the fixing holes. Then, the pull rod is adjusted vertically to raise or lower the extension rod. Once the pull rod position is properly adjusted, the two sets of pull blocks are released, causing the second spring to expand and allowing the fixing posts on both sides to simultaneously insert into the corresponding fixing holes. The height of the pull rod is then fixed. By setting the adjustment component, the main body of the measuring instrument is easily pulled, avoiding the need for the operator to bend over and move the main body when the pull rod is too low, which is more strenuous. This effectively improves the practicality of the equipment. Attached Figure Description

[0023] Please see Figures 1-5 This utility model provides a technical solution: a portable forestry measuring device, including a measuring instrument body 1, a support 2 and a moving component 3. The support 2 is fixedly connected to the lower surface of the measuring instrument body 1. The measuring instrument body 1 is provided with a rotating block 31, which is rotatably connected to the surface of the measuring instrument body 1. The moving component 3 is provided on the surface of the rotating block 31.

[0024] The following section will explain the specific settings and functions of the moving component 3 and the adjusting component 4.

[0025] In this embodiment: the moving component 3 includes a wheel 32, which is fixedly connected to the surface of the rotating block 31, and the surface of the measuring instrument body 1 is rotatably connected to a fixed block 33, which is located on the outside of the rotating block 31.

[0026] Specifically, there are two sets of rotating blocks 31 arranged symmetrically. A spring 34 is fixedly connected to the inner wall of the fixed block 33. A slider 35 is fixedly connected to the surface of the spring 34. The slider 35 is slidably connected to the inner wall of the fixed block 33.

[0027] Specifically, the surface of the fixed block 33 is provided with a groove 36, the surface of the slider 35 is fixedly connected with a toggle block 37, the surface of the slider 35 is fixedly connected with a rod 38, and the rod 38 is slidably connected to the inner wall of the groove 36.

[0028] Specifically, a rod 38 is fixedly connected to the surface of the slider 35, and a positioning groove 39 is opened on the surface of the rotating block 31. The rod 38 is inserted and connected to the inner wall of the positioning groove 39.

[0029] The effects achieved by the above components are as follows: by setting the rotating block 31, the wheel 32 can be rotated and adjusted along the axis of the rotating block 31, so that the wheel 32 can be rotated after use and the wheel 32 can be retracted; by setting the spring 34, the spring force of the spring 34 can drive the insertion rod 38 to move after the lever 37 loses its force; by setting the connection between the insertion rod 38 and the positioning groove 39, the wheel 32 can be fixed and the wheel 32 can be prevented from rotating along the axis of the rotating block 31 due to lack of restraint.

[0030] Specifically, the surface of the measuring instrument body 1 is provided with an adjustment component 4. The adjustment component 4 includes a fixing plate 41, which is fixedly connected to the surface of the measuring instrument body 1. A sleeve rod 42 is fixedly connected to the upper surface of the fixing plate 41. There are two sets of sleeve rods 42. A fixing plate 43 is fixedly connected to the surface of the measuring instrument body 1. The fixing plate 43 is located above the fixing plate 41.

[0031] Specifically, an extension rod 44 is slidably connected to the inner wall of the sleeve rod 42, and the extension rod 44 is inserted into the inner wall of the fixing plate 43. A pull rod 45 is fixedly connected to the upper surface of the extension rod 44.

[0032] Specifically, the inner wall of the second fixing plate 43 is slidably connected with a fixing post 46. There are two sets of fixing posts 46 arranged symmetrically. A pull block 47 is fixedly connected to the surface of the fixing post 46. The pull block 47 is located on the outer side of the second fixing plate 43. A spring 48 is fixedly connected to the surface of the fixing post 46. The surface of the extension rod 44 is provided with fixing holes 49. There are multiple sets of fixing holes 49 arranged in an array. The fixing post 46 is inserted into the inner wall of the fixing hole 49.

[0033] The effects achieved by the above components are as follows: by setting the sleeve rod 42, it is easy to store the extension rod 44, so that the extension rod 44 can be stored inside the sleeve rod 42 when no lengthening is required; by setting the second spring 48, it is easy to compress the second spring 48 when the two sets of fixing posts 46 are simultaneously subjected to pressure towards the middle. However, after the fixing posts 46 are unrestrained, the rebound force of the second spring 48 can drive the fixing posts 46 to be inserted into the corresponding fixing holes 49, so as to fix the position and length of the extension rod 44.

[0034] Working principle: By setting the moving component 3, the use of the wheel 32 is more convenient when moving the measuring instrument body 1. Pulling the lever 37 causes the adjusting rod 38 to leave the inner wall of the positioning groove 39, causing the spring 34 to be stretched and expanded, and then the wheel 32 to rotate stably along the axis of the rotating block 31, so that the wheel 32 is in the ground. After the position of the wheel 32 is adjusted, the lever 37 is released, and the rebound force of the spring 34 drives the rod 38 to be inserted into the inner wall of the positioning groove 39, fixing the rotating block 31, thus fixing the wheel 32 stably. By setting the moving component 3, it is easy to move the measuring instrument body 1, avoiding the fact that existing measuring equipment is generally very heavy, and forestry workers carrying boxes for long distances are physically exhausted. If forestry workers are physically exhausted, it is very dangerous in the forest, which may not only cause personal injury to forestry workers, but also damage to measuring equipment. Therefore, the convenience of the equipment is effectively improved.

[0035] Furthermore, by setting the adjustment component 4, the use of the wheels 32 is more convenient when pulling the main body 1 of the measuring instrument. To this end, the two sets of pull blocks 47 are pulled by hand, which compresses the second spring 48 and causes the two sets of fixing posts 46 to simultaneously leave the inner wall of the fixing hole 49. Then, the pull rod 45 is adjusted vertically to adjust the height of the extension rod 44. After the position of the pull rod 45 is adjusted properly, the two sets of pull blocks 47 are released, which causes the second spring 48 to stretch and expand, allowing the fixing posts 46 on both sides to be inserted into the corresponding fixing holes 49 simultaneously. Then, the height of the pull rod 45 is fixed. By setting the adjustment component 4, it is easier to pull the main body 1 of the measuring instrument, avoiding the need for the operator to bend over and move the main body 1 of the measuring instrument when the pull rod 45 is in a low position, which is more strenuous. This effectively improves the practicality of the equipment.
