Under the cooperation of a driving bevel gear 96 and three driven bevel gears 97, the four threaded rods 92 can be rotated at the same time. Then, the three driven bevel gears 97 are set, so that when the driving bevel gear 96 rotates, the three driven bevel gears 97 and the corresponding threaded rods 92 can be rotated. Under the restriction of the slide 10, the threaded sleeve 93 and the clamping plate 94 are moved horizontally to clamp the workpiece. However, the clamping The inner side walls of the holding plates 94 are provided with rubber pads 95, which make the workpiece clamped more tightly and not easy to slide. The two adjacent bevel gears are meshed for transmission. The four sides of the upper end of the processing table 7 are provided with slide grooves 10 for guiding. The surface of the clamping plate 94 is bonded with rubber pads 95 to improve the tightness. Under the restriction of the slide groove 10, the threaded sleeve 93 and the upper clamping plate 94 can move in a straight line without offset or misalignment. Therefore, by adjusting the position of the four clamping plates 94, workpieces of different sizes can be quickly clamped and fixed, and the adaptability is wider.

The two adjacent bevel gears are engaged for transmission and processing. The four sides of the upper end of the table 7 are provided with slide grooves 10 for guiding. The surface of the clamping plate 94 is bonded with a rubber pad 95 to improve the tightness. Under the restriction of the slide groove 10, the threaded sleeve 93 and the upper clamping plate 94 can move in a straight line without offset or misalignment. Therefore, by adjusting the position of the four clamping plates 94, workpieces of different sizes can be quickly clamped and fixed, and the adaptability is wider. By pressing the positioning rods 65 on both sides of the fixed block 2 into the movable grooves 61 on the movable block 3, the fixation is released at this time, and the processing table 7 can be adjusted to adjust the direction of the clamped workpiece. Further, the positioning rod 65 will pop out under the elastic force of the spring 66 and engage with the positioning hole 5 again to complete the fixation. In this way, the clamp can adjust the direction of the workpiece, and the operation is more convenient.

The fixing block 2 is provided with a plurality of positioning holes 5 on both sides, and the surface of the positioning rod 65 is engaged with one of the positioning holes 5, which plays a role in limiting. The upper and lower ends of the movable plate 64 are fixedly connected to the limiting blocks 63, and the two ends of the inner wall of the movable groove 61 are provided with limiting grooves 62. The outer surface of the limiting block 63 is slidably connected with the inner wall of the limiting groove 62, which plays a role in limiting guide. Further, bolts are used to install it around the surface of the mounting plate 1. By pressing the positioning rods 65 on both sides of the fixing block 2 into the movable grooves 61 on the movable block 3, the fixed state of the movable block 3 can be released. The outer diameter of the movable plate 64 is the same as the inner diameter of the movable groove 61 and is slidably connected, so that the positioning rod 65 is more stable when moving, and the setting of the limiting blocks 63 and the limiting grooves 62 prevent the movable plate 64 from deviating and falling off. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
