Through the cooperation of the motor 4 and the limiting wheel 5, the motor 4 drives the limiting wheel 5 to rotate, and then the limiting wheel 5 drives the bottom column 6 and the top column 10 to rotate synchronously. Through the cooperation of the tension spring 14 and the push rod 15, the tension spring 14 drives the push rod 15 to move down, and then the push rod 15 drives the push plate 16 to move down, and the airbag 17 is used to stably clamp and limit the tool.

[0022] In a preferred embodiment, the inner wall of the tool magazine 2 is provided with an auxiliary groove 12. The inner wall of the top groove 11 is connected to the inner wall of the airbag 17 through the inner wall of the auxiliary groove 12. The inner wall of the fixed cylinder 1 is provided with an auxiliary groove 13. The inner wall of the bottom groove 7 is connected to the inner cavity of the fixed cylinder 1 through the inner wall of the auxiliary groove 13. Through the cooperation of the auxiliary groove 12 and the top groove 11, the top groove 11 rotates with the top column 10, and the auxiliary top groove 11 aligns with the inner wall of the auxiliary groove 12 at the position where the tool needs to be removed, thereby assisting the gas inside the airbag 17 to be discharged. This facilitates the pusher plate 16 to push the tool out of the device after the inner wall of the auxiliary groove 13 aligns with the inner wall of the bottom groove 7.

[0023] In a preferred embodiment, an air pump 8 is fixedly mounted on the top of the bottom column 6, and the top of the air pump 8 is fixedly mounted on the bottom of the top column 10. The inner walls of the bottom groove 7 and the top groove 11 are connected to the inner walls of the air pump 8. By adding the air pump 8, the gas inside the bottom groove 7 and the gas inside the top groove 11 can be connected, thereby assisting the gas to be replenished as needed.

[0024] In a preferred embodiment, a slide cylinder 19 is fixedly mounted on the top of the tool magazine 2. A tension spring 20 is fixedly connected to the bottom of the inner wall of the slide cylinder 19, and a slide rod 21 is fixedly connected to the top of the tension spring 20. The inner wall of the slide cylinder 19 is connected to the inner wall of the top groove 11. A clamping frame 22 is fixedly mounted on the top of the slide rod 21. Through the cooperation of the tension spring 20 and the slide rod 21, the tension spring 20 pulls the slide rod 21 downward, and the slide rod 21 drives the clamping frame 22 downward, thereby assisting the clamping frame 22 in clamping and limiting the tool.

[0025] In a preferred embodiment, a motor 23 is fixedly mounted on the top of the clamping frame 22. A drive gear 24 is fixedly sleeved on the output shaft of the motor 23. A rotating gear 25 is rotatably connected to the inner wall of the clamping frame 22, and the protruding teeth on the outer edge of the rotating gear 25 mesh with the protruding teeth on the outer edge of the drive gear 24.

A clamping cylinder 27 is fixedly mounted on the side of the inner wall of the clamping rod 26. A spring 28 is fixedly connected to the side of the inner wall of the clamping cylinder 27, and a round rod 29 is fixedly connected to the end of the spring 28 away from the inner wall of the clamping cylinder 27. A clamping plate 30 is fixedly mounted on the side of the round rod 29. Through the cooperation of the motor 23 and the drive gear 24, the motor 23 drives the drive gear 24 to rotate, which in turn drives the rotating gear 25 to rotate in opposite directions. Thus, the drive gear 24 and the rotating gear 25 drive the clamping rod 26 to rotate in opposite directions, thereby assisting the opposing clamping plates 30 in clamping and limiting the required tool.

[0026] In a preferred embodiment, a second spring 31 is fixedly connected to the inner wall of the base 3, and a protruding rod 32 is fixedly connected to the end of the second spring 31 away from the inner wall of the base 3. The shape and size of the convex surface of the protruding rod 32 are adapted to the shape and size of the inner wall of the groove of the limiting wheel 5. Through the cooperation of the second spring 31 and the protruding rod 32, the second spring 31 pushes the protruding rod 32 to move in the inner wall of the base 3, thereby using the convex surface of the protruding rod 32 to fit and limit the groove of the limiting wheel 5, thereby assisting the limiting wheel 5 to drive the base 3 to limit the position.

[0027] Working principle: When the device is in use, the motor 4 drives the limit wheel 5 to rotate, and the limit wheel 5 drives the bottom column 6 and the top column 10 to rotate. Then, the top groove 11 rotates with the top column 10, and the top groove 11 aligns with the inner wall of the auxiliary groove 12 where the tool needs to be removed. This helps to expel the gas inside the airbag 17. After the inner wall of the auxiliary groove 13 aligns with the inner wall of the bottom groove 7, the push plate 16 pushes the tool out of the device. When the top groove 11 is evacuated, the tension spring 20 drives the slide rod 21 to move down, which in turn drives the clamping frame 22 to move down. The auxiliary clamping frame 22 and the tool are on the same horizontal plane. Then, the motor 23 drives the drive gear 24 to rotate, which in turn drives the rotating gear 25 to rotate in opposite directions. This causes the clamping rod 26 to move in opposite directions, and the spring 28 pushes the round rod 29 to move in the inner wall of the clamping cylinder 27. Thus, the clamping plate 30 stably clamps and limits the required tool.
