[0023] An installation groove 8 and a sliding hole 9 are provided inside the moving nut 2, the locking device 6 includes a limiting rod 61, a limiting plate 62 is sleeved outside the limiting rod 61, by providing the limiting rod 61 and the sliding hole 9, the limiting rod 61 cooperates with the sliding hole 9, realizing the limiting of the limiting rod 61 by the sliding hole 9 and avoiding the shaking of the limiting rod 61 during sliding;

[0024] A handle 63 is connected to the limiting plate 62, a pulling spring 64 is sleeved outside the limiting rod 61, by providing the pulling spring 64, when the handle 63 is not pulled, at this time the pulling spring 64 applies an elastic force to the limiting plate 62 to keep it stable, when the handle 63 is released, at this time the pulling spring 64 applies an elastic force to the limiting plate 62, the elastic force drives the limiting plate 62 to move, and the limiting plate 62 drives the limiting rod 61 to move, so as to realize its quick reset;

[0025] One end of the pulling spring 64 is connected under the limit plate 62, and the other end of the pulling spring 64 is connected to the moving nut 2. The limit rod 61 is clamped in the limit groove 66. The mounting plate 65 is slidably connected in the mounting groove 8. The mounting plate 65 is connected to one side of the clamping plate 5. The mounting plate 65 is clamped outside the limit rod 61, and a limit groove 66 is formed in the mounting plate 65.

[0026] The working principle of the present utility model is as follows:

[0027] When different metal parts need to be clamped, at this time, pull the handle 63, and the handle 63 drives the limit plate 62 and the limit rod 61 to move. At this time, the limit rod 61 gradually moves away from the limit groove 66. After the limit rod 61 moves away from the limit groove 66, pull the clamping plate 5 at this time, and the clamping plate 5 drives the mounting plate 65 to move.

When the positions of the limit rod 61 and the limit groove 66 correspond to each other, release the handle 63 at this time. The pulling spring 64 applies an elastic force to the limit plate 62, and the elastic force drives the limit plate 62 to move. The limit plate 62 drives the limit rod 61 to move, so that the limit rod 61 is clamped in the limit groove 66. When the air pump 73 is started during the processing, the air flow generated by the air pump 73 is ejected from the nozzle 75 after passing through the pipeline 74. When clamping workpieces of different sizes, at this time, when the moving nut 2 moves, it will drive the slider 72 to slide in the housing 71 through the connecting plate 76, and position the components such as the air pump 73 between the two clamping plates 5. Thus, the replacement of the clamping plate 5 and the cleaning inside the clamping plate 5 are completed.
