[0021] The following is a detailed description of a marking pliers for forest survey provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the embodiment of the utility model provides a marking pliers for forest survey, comprising a first pliers body 1 and a second pliers body 4;

[0023] The first pliers body 1 and the second pliers body 4 are rotatably connected via a rotatable connecting piece 3. A marking head 7 is detachably mounted on the first pliers body 1 or the second pliers body 4 via a first connecting portion 9 and a fastener 2. A bark thickness detector 8 is mounted on the first connecting portion 9. A handle structure 5 is provided on the first pliers body 1 and the second pliers body 4.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the grip structure 5 includes an extended handle 502 , and the extended handle 502 is detachably connected to the first pliers body 1 and the second pliers body 4 via a second connecting portion 501 .

[0025] When the extended handle 502 is not needed, it can be disassembled in time, thereby improving the practicality of the marking pliers.

[0026] like Figure 3 As shown, the shape of the extended handle 502 is designed based on ergonomic principles and is made of anti-slip and shock-absorbing materials.

[0027] The function of the extended handle 502 is to improve the comfort and work efficiency of the operator, while reducing fatigue and the risk of accidental injury during operation; the ergonomically designed extended handle 502 can better adapt to the hand structure of the operator, thereby providing a more comfortable grip feeling and reducing the discomfort caused by long-term operation. This design usually takes into account the user's hand size, grip strength and natural posture during operation to ensure a good match between the tool and the hand;

[0028] The application of anti-slip materials can increase the friction coefficient of the handle surface, ensuring a firm grip even when wet or with sweaty hands, preventing the tool from slipping and thus improving the safety of operation; the use of shock-absorbing materials can effectively absorb and reduce the vibration transmitted to the hands during operation, which is especially important for operators who perform repetitive work for a long time, because it helps reduce fatigue in the hands and arms and avoid chronic injuries caused by vibration.

[0029] like Figure 3 As shown, an adjustment strap 503 is installed on the extended handle 502.

[0030] The function of the adjustment strap 503 is to provide additional safety and stability, making the operation more comfortable and reliable. The adjustment strap 503 can be adjusted according to the operator's hand size to ensure that the extended handle 502 fits closely to the hand, reducing sliding or shifting during operation, thereby improving the stability of the operation; the adjustment strap 503 can make the handle fit the hand curve more closely, disperse the pressure of the extended handle 502 on the hand, and reduce the fatigue caused by long-term operation. In a slippery environment or when performing strong operations, the adjustment strap 503 can effectively prevent the tool from slipping from the hand, thereby ensuring the safety of the operation.

[0031] like Figure 1 and Figure 2 As shown, a depth adjustment recorder 6 is installed on the first pliers body 1 or the second pliers body 4, and the depth adjustment recorder 6 includes a display screen and a control button.

[0032] The function of the depth adjustment recorder 6 is to accurately control and record the depth of the marking clamp entering the wood to ensure the consistency and accuracy of the marking. The user adjusts the depth of the marking clamp entering the red sandalwood through the control button and monitors the current depth in real time through the display screen. This design is crucial to ensuring the quality of marking. When multiple markings are made, it can ensure that the depth of each mark is carried out in accordance with the preset standard, so that the marking results are comparable. By accurately controlling the depth of the jaws entering the tree, unnecessary damage to the tree can be avoided, especially when marking ancient trees or rare tree species. The depth adjustment recorder 6 can record the depth data of each mark, which is convenient for subsequent analysis and tracking, and is helpful for resource investigation and research.

[0033] The depth adjustment recorder 6 uses a sensor to sense the depth of the marking clamp entering the wood, and detects it as a physical quantity; the physical quantity captured by the sensor will be converted into an electrical signal, which will be sent to the analog-to-digital conversion hardware and converted into a digital signal. The converted digital signal will be stored by the recorder for subsequent data analysis and tracking. The user can operate the depth adjustment recorder 6 through the control button, set the required depth and monitor the current status in real time.

[0034] like Figure 1 and Figure 2 As shown, the inner sides of the first caliper body 1 and the second caliper body 4 are arranged in a tooth pitch shape.

[0035] The inner sides of the first pliers 1 and the second pliers 4 are arranged in a pitch shape to improve the clamping stability and prevent slipping. The pitch-shaped surface increases the friction between the clamped object and provides a better grip to prevent the object from sliding during the clamping process. When marking red sandalwood trees, the pitch-shaped pliers can more accurately locate and fix the object, avoiding errors caused by the movement of the object.

[0036] like Figure 1 and Figure 2 As shown, the first caliper body 1 and the second caliper body 4 are made of hard alloy, and the surface is coated with an anti-corrosion coating.

[0037] In the marking work of red sandalwood, since red sandalwood is hard and heavy, the wear resistance and hardness of the tools are extremely high. Using cemented carbide as the pliers material can ensure that the marking pliers can still maintain good working performance after long-term use and are not easy to wear or damage; the purpose of coating the surface with anti-corrosion coating is to protect the tools from corrosion by corrosive substances and extend their service life. Since the marking pliers may come into contact with tree sap, rainwater or other corrosive substances during use, the anti-corrosion coating can effectively prevent these substances from corroding the pliers body, thereby maintaining the stability and reliability of the pliers body.

[0038] The technical solution provided by the utility model is that when in use, the user holds the extended handle 502, adjusts the strap 503 to assist the hand in supporting the hand, drives the first clamp body 1 and the second clamp body 4 to move, until the first clamp body 1 and the second clamp body 4 move and contact the red sandalwood, and the depth adjustment recorder 6 detects and determines the depth required for marking the tree, and leaves a mark on the red sandalwood through the marking head 7.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
