[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, an embodiment provided by the present utility model: a vertical tensile testing machine with precise measurement, including a bottom support plate 1, a support seat 14 is fixedly connected to the middle of the top end of the bottom support plate 1, a display screen 2 is fixedly connected to the front side of the top end of the bottom support plate 1, a support frame 10 is fixedly connected to the rear side of the top end of the bottom support plate 1, a threaded rod 11 is rotatably connected inside the support frame 10, a lifting tensile plate 7 is threadedly connected to the outside of the threaded rod 11, a driving motor 8 is fixedly connected to the top end of the support frame 10, a tensile sensor 16 is fixedly connected to the middle of the inner side of the support seat 14, the output end of the tensile sensor 16 is fixedly connected to a lower hook 17, an upper pull column 19 is nested inside the lower hook 17, the top end of the upper pull column 19 is fixedly connected to a lower clamp 12, a quick-release component is installed inside the support seat 14, the bottom end of the lifting tensile plate 7 is fixedly connected to an upper clamp 6, a blocking and protecting component is installed on the front side of the upper clamp 6. The quick-release component includes a mounting seat 13 located at the top of the support seat 14, mounting sliders 3 are fixedly connected to both sides of the bottom end of the mounting seat 13, positioning pins 18 are inserted through both sides of the support seat 14, and the inner sides of the outside of the positioning pins 18 are respectively nested inside the mounting sliders 3. The outside of the upper pull column 19 is slidably connected inside the mounting seat 13, the outside of the lifting tensile plate 7 is slidably connected inside the support frame 10, the driving end of the driving motor 8 is fixedly connected to the top end of the threaded rod 11, and the display screen 2 is electrically connected to the tensile sensor 16;

[0026] Clamp the object to be tested at both ends through the lower clamp 12 and the upper clamp 6 respectively. Start the driving motor 8 to drive the threaded rod 11 to rotate. The external thread of the threaded rod 11 contacts the internal thread of the lifting tensile plate 7, thereby lifting the lifting tensile plate 7 upward. As the upper clamp 6 exerts force on the object, a tensile force is generated on the object. The force is transmitted to the upper pull column 19 through the lower clamp 12, and then connected to the lower hook 17 through the upper pull column 19, and the tensile force is transmitted to the inside of the tensile sensor 16 and reflected outward through the display screen 2. Long-term use will cause wear to the bottom. At this time, pull out the outside of the positioning pin 18 and apply an external force to the mounting seat 13. The mounting slider 3 slides inside the support seat 14, thereby removing the mounting seat 13, so as to perform maintenance and replacement on it, avoid excessive wear on the bottom caused by long-term use, facilitate the maintenance work of the device, and have a longer service life.

[0027] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5, the blocking and protecting component includes a fixed seat 9 located at the front end of the upper clamp 6. An upper guard plate 5 is rotatably connected to the outside of the fixed seat 9. A lower guard plate 4 is slidably connected to the inside of the upper guard plate 5. A magnetic attraction block 20 is fixedly connected to the inner bottom of the lower guard plate 4. A fixing groove 15 is formed on the front side of the lower clamp 12. The outside of the magnetic attraction block 20 is magnetically connected to the inside of the fixing groove 15;

[0028] With the pulling force generated by the lifting tension plate 7 on the object, when the pulling force borne by the object is too large, the object breaks. Due to the strong elasticity generated by the break, it directly acts on the inner sides of the lower guard plate 4 and the upper guard plate 5, blocking the broken object to prevent splashing, protecting the safety of the staff, avoiding damage to the staff caused by the strong elastic force of the broken object, and improving the detection safety of the device.

[0029] Working principle: Clamp both ends of the object to be detected through the lower clamp 12 and the upper clamp 6 respectively. Start the driving motor 8 to drive the threaded rod 11 to rotate, thereby lifting the lifting tension plate 7 upward. As the upper clamp 6 exerts force on the object and generates a pulling force on the object, the force is transmitted to the upper pull column 19 through the lower clamp 12, and then connected to the lower hook 17 through the upper pull column 19, transmitting the pulling force to the inside of the tension sensor 16, and reflecting it to the outside through the display screen 2. Long-term use will cause wear to the bottom. At this time, pull out the outside of the positioning pin 18 and apply an external force to the mounting seat 13. The mounting slider 3 slides inside the support seat 14, thereby removing the mounting seat 13 and performing maintenance and replacement on it. With the pulling force generated by the lifting tension plate 7 on the object, when the pulling force borne by the object is too large, the object breaks. Due to the strong elasticity generated by the break, it directly acts on the inner sides of the lower guard plate 4 and the upper guard plate 5, blocking the broken object to prevent splashing, protecting the safety of the staff.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
