The inner wall of the movable frame 403 is slidably connected to two movable blocks 405. The upper surface of the fixed frame 401 is fixedly connected to two connecting columns 5, and the upper surface of each connecting column 5 is fixedly connected to the inner top wall of the support frame 1. By setting the connecting columns 5, the fixed frame 401 can be fixedly connected to the support frame 1, so that the detection device can work stably.

[0026] The two movable blocks 405 are fixedly connected to a movable column 407 on one side away from each other, and the inner wall of the movable frame 403 is fixedly connected to two fixed plates 406. The outer surface of each movable column 407 is slidably connected to the inner wall of the fixed plate 406. The inner wall of the fixed plate 3 is slidably connected to three movable frames 8. The inner wall of each movable frame 8 is movably hinged with a push rod 11. By setting the movable frame 8 and the push rod 11, it is possible to provide thrust when the tool body 402 is limited and fixed. At the same time, the push rod 11 can easily drive the remaining movable frames 8 to move, thereby realizing the connecting rod working effect.

[0027] The side surfaces of the two moving blocks 405 that are away from each other are fixedly connected with springs 408, and the ends of the two springs 408 that are away from each other are fixedly connected to the outer surface of the fixed plate 406. The right side surface of one of the moving frames 8 is fixedly connected with a first electric telescopic rod 7, and the outer surface of the first electric telescopic rod 7 is fixedly connected to the inner wall of the fixed disk 3. By setting the first electric telescopic rod 7, the power required for limiting and fixing can be provided, thereby quickly performing the tool changing operation.

By setting the limiting plate 9, the tool body 402 can be limited under the drive of power, thereby increasing the firmness of the tool body 402.

[0029] The outer surface of each threaded rod 411 is threadedly connected to the inner wall of the movable plate 409, the inner wall of the fixed plate 3 is slidably connected to the tool body 402, the inner walls of the three push rods 11 are jointly movably hinged with a rotating ring 10, the outer surface of the rotating ring 10 is rotatably connected to the inner wall of the fixed plate 3, and the inner wall of the rotating ring 10 is slidably connected to the outer surface of the tool body 402. By setting the rotating ring 10, it can rotate under the push of the push rod 11, thereby facilitating the movement and limiting of other limit plates 9.

[0030] The working principle of the utility model is as follows: when in use, the staff first transports the device to a suitable use position, then connects the power of the engraving machine body 2, the multi-stage electric telescopic rod 404, the pressure sensor 410 and the first electric telescopic rod 7, so that they can be in a stable power-on state, and then the staff turns on the first electric telescopic rod 7, and the first electric telescopic rod 7 begins to shorten after being turned on. The shortening of the first electric telescopic rod 7 can pull one of the moving frames 8 and the limit plate 9 to move backward, and when the moving frame 8 moves backward, it can pull the push rod 11 to move, and the movement of the push rod 11 can pull the rotating ring 10 and the remaining limit plates 9 and the moving frame 8 to move until the limit on the tool body 402 is released, and the tool body 402 is taken out and replaced with a suitable tool body 402, and at the same time the first electric telescopic rod 7 is controlled to move the tool The main body 402 is re-limited, and then the multi-stage electric telescopic rod 404 and the pressure sensor 410 are turned on. After the multi-stage electric telescopic rod 404 is turned on, it can push the moving frame 403 to move until it moves to the bottom of the tool body 402. At the same time, the engraving machine body 2 is turned on to control the tool body 402 to press down. The tool body 402 is pressed down to apply pressure to the two moving blocks 405. The two moving blocks 405 can move to both sides. The movement of the moving block 405 can drive the movable column 407 to move. After moving to a suitable distance, the movable column 407 can contact and trigger the pressure sensor 410. When the surface of the tool body 402 is severely worn, the moving distance of the moving block 405 will be reduced, so that it can be judged that the surface of the tool body 402 is severely damaged and cannot be used anymore and needs to be replaced again.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
