[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model: a material tensile testing device for engineering supervision, including a handle 1. The right end of the inner wall of the handle 1 is rotatably connected to a fixed shaft 3. The fixed shaft 3 provides a rotation connection point for the pressing grip 4 to facilitate the pressing operation. The middle part of the outer wall of the fixed shaft 3 is rotatably connected to a pressing grip 4. The operator starts the detection process by pressing the pressing grip 4. The left side of the inner wall of the handle 1 is fixedly connected to a fixed head 5. The fixed head 5 plays a role in connecting and fixing the ejector rod 6. The right end of the fixed head 5 is fixedly connected to an ejector rod 6. The ejector rod 6 displaces under the action of the pressing grip 4, thereby driving the subsequent components to move. The right end of the ejector rod 6 is fixedly connected to a damping shaft 7. The damping shaft 7 ensures the smooth movement of the detection cross bar 8. The middle part of the ejector rod 6 penetrates through the right side of the pressing grip 4, so that the movement of the pressing grip 4 can be effectively transmitted to the ejector rod 6. Both the upper and lower ends of the damping shaft 7 are rotatably connected to a detection cross bar 8. The detection cross bar 8 connects the lateral force detector 9 and the damping shaft 7. The far ends of the two detection cross bars 8 are fixedly connected to a lateral force detector 9 respectively. The lateral force detector 9 is responsible for detecting the lateral tensile force received by the material. The right ends of the two lateral force detectors 9 are fixedly connected to a fixed cone 10. The fixed cone 10 is used to fix on the material to be detected. A rebound assembly is arranged in the middle of the outer wall of the ejector rod 6. The rebound assembly restores the device to its initial state after the detection is completed. A detection head fixing and storage mechanism 2 is arranged on the right side of the pressing grip 4. The detection head fixing and storage mechanism 2 can fix and store the lateral force detector 9 and the fixed cone 10;

[0033] Specifically, when conducting material tensile testing, the operator holds the handle 1. The handle 1 provides a stable gripping part for the entire device, facilitating operation. The fixed shaft 3 serves as the rotational connection point for pressing the grip 4. When the operator presses the pressing grip 4 inward, the pressing grip 4 rotates around the fixed shaft 3. The fixed head 5 is fixed to the left inner wall of the handle 1, playing a role in connecting and fixing the ejector rod 6. The ejector rod 6 displaces under the action of the pressing grip 4. When the pressing grip 4 is pressed, the ejector rod 6 moves to the right, and the damping shaft 7 at its right end also moves to the right accordingly. The detection crossbar 8 rotatably connected to the upper and lower ends of the damping shaft 7 starts to act under the drive of the damping shaft 7. Due to the action of the damping shaft 7, the movement of the detection crossbar 8 is relatively stable and there will be no sudden large swings. The lateral force detectors 9 at the far ends of the detection crossbar 8 start to work. When the fixed cones 10 at the right ends of the two lateral force detectors 9 are fixed to the material to be tested, as the ejector rod 6 moves, the lateral force detectors 9 can detect the lateral tensile force received by the material. The rebound assembly in the middle of the outer wall of the ejector rod 6 plays a role in restoring the device to its initial state after the detection is completed. When the pressing grip 4 is released, the rebound assembly pushes the ejector rod 6 to the left, so that the detection component returns to its initial position for the next detection, improving the efficiency of the detection work and ensuring the consistency and reliability of the device during multiple uses, making the detection results repeatable, achieving the effects of convenient operation, stable detection, and high-efficiency repeatability, and providing strong support for material detection in engineering supervision.

[0034] Referring to Figure 4 and Figure 5 , the detection head fixing and receiving mechanism 2 includes two Z-shaped plates 201. The Z-shaped plates 201 are used to clamp the lateral force detectors 9. Adjustment holes 202 are provided on the far sides of the two Z-shaped plates 201. The adjustment holes 202 provide installation positions for the fixing bolts 203. Fixing bolts 203 are arranged on the inner walls of the two adjustment holes 202. The fixing bolts 203 are used to fix the Z-shaped plates 201 and the lateral force detectors 9. Fastening knobs 204 are fixedly connected to the far ends of the two fixing bolts 203. The fastening knobs 204 facilitate the operator to rotate the fixing bolts 203. Threaded holes 205 are provided on the far sides of the two lateral force detectors 9. The threaded holes 205 cooperate with the fixing bolts 203 to achieve fixation. A rotating shaft 206 is fixedly installed on the middle right side of the ejector rod 6. The rotating shaft 206 facilitates the storage and angle adjustment of the detection head;

[0035] Specifically, during use, when it is necessary to fix the lateral force detector 9 and the fixing cone 10, the operator rotates the fastening knob 204. The fastening knob 204 drives the fixing bolt 203 to rotate, causing the fixing bolt 203 to move towards the lateral force detector 9. Since the two Z-shaped plates 201 are in a fixed state, when the fixing bolt 203 mates with the threaded hole 205 on one side of the lateral force detector 9, as the fixing bolt 203 is continuously tightened, the two Z-shaped plates 201 and the two lateral force detectors 9 are respectively fixed by the two fixing bolts 203, thereby achieving the fixation of the lateral force detector 9 and the fixing cone 10. When it is necessary to store the device or adjust the position of the detection head, the rotating shaft 206 on the right side near the middle of the ejector rod 6 can rotate the detection part on the right side of the ejector rod 6, adjust it to an appropriate angle or store it, so as to be convenient for carrying and storing, making the device more compact when not in use, reducing the occupied space, and at the same time being able to quickly and accurately fix the detection head during use, ensuring the smooth progress of the detection work, and providing convenience and reliability for the use and storage of the device.

[0036] Refer to Figure 2 、 Figure 3 and Figure 4 , the rebound assembly includes a fixing piece 11. The fixing piece 11 plays a role in connecting the ejector rod 6 and the pressing grip 4. The fixing piece 11 is fixedly connected to the middle of the outer wall of the ejector rod 6 to ensure the connection stability between the rebound assembly and the ejector rod 6 during operation. The right side of the fixing piece 11 is fixedly connected to the right inner wall of the pressing grip 4, so that the movement of the pressing grip 4 can be transmitted to the rebound assembly. The left side of the fixing piece 11 is fixedly connected with a tension spring 12. The tension spring 12 provides a return force after the detection is completed to make the device return to its initial state. The left end of the tension spring 12 is fixedly connected to the right side of the fixing head 5 to ensure the stable fixing position of the tension spring 12; on the left side of the top of the handle 1, a display screen 13 is fixedly connected. The display screen 13 is used to display the pulling force value detected by the lateral force detector 9 in real time. The display screen 13 is electrically connected to the two lateral force detectors 9 to ensure the accurate transmission of data; on the left outer wall of the handle 1, anti-slip particles 14 are fixedly connected. The anti-slip particles 14 increase the friction of the handle 1 to prevent the hand from slipping. The anti-slip particles 14 are made of anti-slip rubber material to improve the anti-slip effect;

[0037] Specifically, the fixing piece 11 serves to connect the ejector rod 6 and the pressing grip 4. After the detection is completed, the tension spring 12 can provide a resilience force to move the ejector rod 6 to the left, driving components such as the damping shaft 7, the detection cross bar 8, the lateral force detector 9, and the fixing cone 10 back to their initial positions to prepare for the next detection. The display screen 13 is electrically connected to the two lateral force detectors 9 and can display in real time the material tensile force values detected by the lateral force detectors 9, providing intuitive and accurate data for project supervision personnel to evaluate and judge the performance of the material. The anti-slip particles 14 are made of anti-slip rubber material, increasing the friction on the outer wall of the handle 1, preventing the operator's hand from slipping during use, and improving the safety and stability of the operation.

[0038] Referring to Figure 1 , Figure 3 and Figure 4 , on the right side of the outer wall of the pressing grip 4, a finger groove 15 is provided. The finger groove 15 facilitates the placement of the operator's fingers, improving the operation comfort. The inner wall of the finger groove 15 is designed with anti-slip features to enhance the friction between the fingers and the pressing grip 4 and prevent slipping. On the right side of the handle 1 and the left side of the pressing grip 4, a plurality of weight-reducing grooves 16 are provided. The weight-reducing grooves 16 reduce the overall weight of the device, facilitating carrying and operation. A small spacing is left between adjacent weight-reducing grooves 16 to ensure the structural stability of the device. In the middle of the left top end of the pressing grip 4, a lead screw 17 is fixedly connected. The lead screw 17 provides an installation and adjustment basis for the adjustment knob 18. The left end of the lead screw 17 is fixedly connected to the left top end of the inner wall of the handle 1 to ensure the stable fixing position of the lead screw 17. The outer wall of the lead screw 17 is threadedly connected to the adjustment knob 18. The adjustment knob 18 can adjust the initial position and operation force of the pressing grip 4 to adapt to different detection requirements and the habits of operators.

[0039] Specifically, the finger groove 15 is provided on the right side of the outer wall of the pressing grip 4, which conforms to the ergonomic design, facilitating the placement of the operator's fingers. At the same time, the inner wall of the finger groove 15 is designed with anti-slip features, further enhancing the operation stability. A plurality of weight-reducing grooves 16 are provided on the handle 1 and the pressing grip 4, reducing the overall weight of the device without affecting its strength, facilitating carrying and operation. A small spacing is left between adjacent weight-reducing grooves 16 to ensure the structural stability of the device. The lead screw 17 connects the left top end of the inner wall of the handle 1 and the middle of the left top end of the pressing grip 4, providing an installation and adjustment basis for the adjustment knob 18. The adjustment knob 18 can adjust the initial position and operation force of the pressing grip 4 by threadedly connecting with the lead screw 17, thereby adapting to different detection requirements and the usage habits of operators.

[0040] Working principle: When conducting a tensile test on a material, the operator holds the handle 1. The handle 1 provides a stable gripping part for the entire device, facilitating operation. The fixed shaft 3 serves as the rotational connection point for pressing the grip 4. When the operator presses the grip 4 inward, the grip 4 rotates around the fixed shaft 3. The fixed head 5 is fixed to the left inner wall of the handle 1, playing a role in connecting and fixing the ejector rod 6. The ejector rod 6 displaces under the action of the grip 4. When the grip 4 is pressed, the ejector rod 6 moves to the right, and the damping shaft 7 at its right end also moves to the right. The detection crossbar 8 rotatably connected to the upper and lower ends of the damping shaft 7 starts to move under the drive of the damping shaft 7. Due to the action of the damping shaft 7, the movement of the detection crossbar 8 is relatively stable and there will be no sudden large swings. The lateral force detectors 9 at the ends away from each other of the detection crossbar 8 start to work. When the fixed cones 10 at the right ends of the two lateral force detectors 9 are fixed on the material to be detected, as the ejector rod 6 moves, the lateral force detectors 9 can detect the lateral tensile force received by the material. The spring-back component in the middle of the outer wall of the ejector rod 6 plays a role in restoring the device to its initial state after the detection is completed. When the grip 4 is released, the spring-back component pushes the ejector rod 6 to the left, thereby returning the detection component to its initial position for the next detection;

[0041] Moreover, during the use process, when it is necessary to fix the lateral force detectors 9 and the fixed cones 10, the operator rotates the fastening knob 204. The fastening knob 204 drives the fixing bolt 203 to rotate, causing the fixing bolt 203 to move towards the lateral force detector 9. Since the two Z-shaped plates 201 are in a fixed state, when the fixing bolt 203 mates with the threaded hole 205 on one side of the lateral force detector 9, as the fixing bolt 203 is continuously tightened, the two Z-shaped plates 201 and the two lateral force detectors 9 are respectively fixed through the two fixing bolts 203, thereby achieving the fixation of the lateral force detectors 9 and the fixed cones 10. When it is necessary to store the device or adjust the position of the detection head, the rotating shaft 206 on the right side of the ejector rod 6 near the right end in the middle of the ejector rod 6 can rotate the detection part on the right side of the ejector rod 6, adjust it to an appropriate angle or store it for easy carrying and storage.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
