DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a clamping limit block with a secondary limiting function, including a clamping seat 1, the inner wall of the clamping seat 1 is rotatably connected to a bolt 2, and a hexagonal groove 21 is provided on the top of the bolt 2. By providing the hexagonal groove 21, the bolt 2 can be rotated using a variety of tools, which is more practical. The inner wall of the clamping seat 1 is slidably connected to a clamping plate 3, and the clamping plate 3 is threadedly connected to the bolt 2. A limiting mechanism 4 is provided on the clamping seat 1, and the bolt 2 can be limited by setting the limiting mechanism 4 to prevent the bolt 2 from being excessively rotated and causing the steel material to be crushed by the clamping plate 3. An ejection mechanism 5 is provided on the bolt 2, and the ejection mechanism 5 can gradually eject the hexagonal wrench inside the hexagonal groove 21 upward to prevent the hexagonal wrench from excessively rotating the bolt 2, thereby preventing the clamping plate 3 from crushing the steel material.

[0024] The above-mentioned limiting mechanism 4 includes a positioning platform 41, a positioning rod 42, a limiting rod 43, a telescopic spring 44, an inclined groove 45, a sliding rod 46, a limiting plate 47, and an auxiliary spring 48; the positioning platform 41 is slidably connected to the inner wall of the pressing seat 1, and a telescopic spring 44 is fixedly installed at the bottom of the positioning platform 41. The end of the telescopic spring 44 away from the positioning platform 41 is fixedly installed on the inner wall of the pressing seat 1. When the pressing plate 3 contacts the steel material, it will squeeze the steel material downward, so that the steel material squeezes the positioning platform 41 downward, so that the positioning platform 41 slides downward on the inner wall of the pressing seat 1 and compresses the telescopic spring 44. An inclined groove 45 is provided on the telescopic positioning platform 41, and the positioning rod 42 is slidably connected to the inner wall of the pressing seat 1. The side wall of the positioning rod 42 is fixedly installed with a sliding rod 46, and the outer wall of the sliding rod 46 fits into the inner wall of the inclined groove 45. When the positioning platform 41 slides downward on the inner wall of the pressing seat 1, the inclined groove 45 will push the sliding rod 46, so that the sliding rod When the limit rod 43 is released, the limit plate 47 can be driven to slide back to its original position through the elasticity of the auxiliary spring 48 and the limit plate 47.

[0025] The ejection mechanism 5 includes a slide plate 51, a T-shaped rod 52, a return spring 53, and an inclined rod 54; the slide plate 51 is slidably connected to the outer wall of the bolt 2, and a T-shaped rod 52 is fixedly installed on the inner wall of the slide plate 51. The end of the T-shaped rod 52 away from the slide plate 51 extends to the inner wall of the hexagonal groove 21. When the slide plate 51 slides upward on the outer wall of the bolt 2, it will drive the T-shaped rod 52 to move upward synchronously. During the upward movement of the T-shaped rod 52, the hexagonal wrench inside the hexagonal groove 21 will be gradually ejected upward to prevent the hexagonal wrench from excessively turning the bolt 2. This can prevent the pressing plate 3 from crushing the steel material. A return spring 53 is fixedly installed on the top of the slide 51, and the end of the return spring 53 away from the slide 51 is fixedly installed on the outer wall of the bolt 2. An inclined rod 54 is fixedly installed on the outer wall of the positioning rod 42. The upper surface of the inclined rod 54 fits the bottom of the slide 51. The positioning rod 42 drives the limit rod 43 to gradually approach the bolt 2, which will drive the inclined rod 54 to move synchronously. At this time, the inclined rod 54 will squeeze the slide 51, causing the slide 51 to slide upward on the outer wall of the bolt 2 and compress the return spring 53.

[0026] Working principle: Place the steel material on the positioning platform 41, and use the hexagonal slot 21 to rotate the bolt 2 with an hexagonal wrench. The rotation of the bolt 2 can drive the clamping plate 3 threadedly connected to it to slide downward on the inner wall of the clamping seat 1. When the clamping plate 3 contacts the steel material, it will squeeze the steel material downward, causing the steel material to squeeze the positioning platform 41 downward, causing the positioning platform 41 to slide downward on the inner wall of the clamping seat 1 and compress the telescopic spring 44. At the same time, the inclined groove 45 on the positioning platform 41 will push the slide rod 46, so that the slide rod 46 drives the positioning rod 42 to slide on the inner wall of the clamping seat 1. At this time, the positioning rod 42 will drive the limiting rod 43 to gradually approach the bolt 2. When the limiting rod 43 is in contact with the outer wall of the bolt 2, the positioning rod 42 will be limited, so that the slide rod 46 cannot drive the positioning rod 42 to slide on the inner wall of the clamping seat 1, and the inclined groove 45 can no longer push the slide rod 46. , which will make the positioning platform 41 unable to slide downward any further. At this time, the pressure plate 3 can cooperate with the positioning platform 41 to clamp and limit the steel material, thereby completing the fixation of the steel material. At the same time, when the limit rod 43 is in contact with the outer wall of the bolt 2, the bolt 2 will be limited by the limit rod 43, so that the bolt 2 can no longer rotate, thereby avoiding the pressure plate 3 from continuously clamping the steel material and preventing the steel material from being crushed. When it is necessary to release the clamping limit on the steel material, press the limit rod 43 downward to make it slide downward on the inner wall of the positioning rod 42. At the same time, the limit rod 43 will drive the limit plate 47 to move downward synchronously. At this time, the limit plate 47 will stretch the auxiliary spring 48. When the limit rod 43 moves downward and disengages from the outer wall of the bolt 2, the bolt 2 can be rotated to drive the pressure plate 3 to slide upward on the inner wall of the clamping seat 1 until the pressure plate 3 releases the pressure on the steel material.

[0027] As the positioning rod 42 drives the limiting rod 43 to gradually approach the bolt 2, it will drive the inclined rod 54 to move synchronously. At this time, the inclined rod 54 will squeeze the slide plate 51, causing the slide plate 51 to slide upward on the outer wall of the bolt 2 and compress the return spring 53. At this time, the slide plate 51 will drive the T-shaped rod 52 to move upward synchronously. During the upward movement of the T-shaped rod 52, the hexagonal wrench inside the hexagonal slot 21 will be gradually pushed upward to prevent the hexagonal wrench from excessively rotating the bolt 2, thereby preventing the clamping plate 3 from crushing the steel material.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
