When clamping the articles, the articles can be effectively prevented from sliding out of the clamping blocks, even the articles with relatively smooth surfaces can be stably clamped through the friction provided by the anti-skid blocks 13, and the clamping reliability is improved. The inner walls of the two sides of the rack 1 are fixedly provided with support arms 3, and the support arms 3 are rotatably connected with movable arms 4 supporting the clamping blocks 5. The two sides of the push plate 8 are integrally provided with connecting edges 9, the inner walls of the clamping blocks 5 are provided with movable openings 12 matched with the connecting edges 9, and the clamping blocks 5 are rotatably connected with the movable arms 4 and the connecting edges 9. With the feeding of the push plate 8, the connecting edges 9 push the clamping blocks 5 on the two sides to move outward, so as to open the clamping blocks 5, and vice versa to tighten the clamping blocks 5. The operation mode is simple and direct, convenient and fast, and the operator can easily control the opening and closing of the clamping blocks 5, realize the rapid clamping and releasing of the articles to be clamped, and improve the work efficiency.
[0021] In the present application, the outer walls of the two clamping blocks 5 are detachably provided with extension rods 15, one end of the extension rod 15 is rotatably connected with a connecting bent rod 17, and the end of the connecting bent rod 17 away from the extension rod 15 is fixedly connected with a clamping plate 18. A plurality of clamping holes 16 are formed in the surface of the extension rod 15, and the clamping holes 16 are threadedly connected with bolts 14, and the extension rod 15 and the mounting sleeve 11 are fixed by the bolts 14. For the articles to be clamped with smaller size, the length of the extension rod 15 inside the mounting sleeve 11 can be adjusted, and the bolts 14 are clamped into the corresponding clamping holes 16 for positioning. The device can flexibly adjust the clamping range according to the actual size of the articles, and adapt to articles of different sizes.
[0022] In the present application, the outer walls of the two clamping blocks 5 are detachably provided with extension rods 15, one end of the extension rod 15 is rotatably connected with a connecting bent rod 17, and the end of the connecting bent rod 17 away from the extension rod 15 is fixedly connected with a clamping plate 18.
