Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4As shown, this utility model provides a bit clamping device with adaptive adjustable aperture, including a base plate 1. A fixing ring 2 is fixedly connected to the upper surface of the base plate 1. A mounting plate 3 is fixedly connected to the inner top surface of the fixing ring 2. A spring 4 is fixedly connected to the lower surface of the mounting plate 3 to apply elastic force to a clamping plate 6. A fixing plate 5 is fixedly connected to the end of the spring 4 away from the mounting plate 3. The clamping plate 6 is fixedly connected to the lower surface of the fixing plate 5, which can quickly fix and remove the bit. It is used for processing with low impact force and spraying and cleaning. A connecting block 7 is fixedly connected to the outer surface of the clamping plate 6. A slot 8 is provided on the connecting block 7. The upper surface of the base plate 1... A support frame 9 is fixedly connected, and a motor 10 is installed on the support frame 9. A lead screw 11 is fixedly connected to the output end of the motor 10. A threaded block 12 is threadedly connected to the lead screw 11. The lead screw 11 moves linearly through the action of the thread, thereby driving the locking block 14 to slide. A fixing rod 13 is fixedly connected to the outer surface of the threaded block 12. The other end of the fixing rod 13 is fixedly connected to the locking block 14. The locking block 14 slides onto the connecting block 7 and connects with the locking groove 8 on the connecting block 7. Then it continues to slide downward, driving the locking plate 6 to slide to clamp and fix the bit. This can stably fix the bit, so that the bit can be cut, ground and other physical processing.

[0025] Specifically, the pallet 6 is provided with anti-slip texture, and a control rod 17 is fixedly connected to the upper surface of the pallet 6 for easy lifting of the pallet 6.

[0026] Furthermore, a handle 18 is fixedly connected to the upper surface of the control lever 17 for pulling up the control lever 17, and a rubber sleeve is provided on the handle 18.

[0027] Furthermore, the fixing ring 2 and the mounting plate 3 are provided with openings, which are movably connected to the control rod 17.

[0028] It is worth noting that the fixing ring 2 is provided with a slot 19, which is slidably connected to the fixing rod 13 for the fixing rod 13 to move.

[0029] It is worth noting that card block 14 is movably connected to card slot 8.

[0030] It is worth mentioning that a support block 16 is fixedly connected to the upper surface of the base plate 1. The support block 16 is rotatably connected to the lead screw 11 and is used to support the other end of the lead screw 11.

[0031] It is worth emphasizing that a telescopic rod 15 is fixedly connected to the lower surface of the threaded block 12, and the other end of the telescopic rod 15 is fixedly connected to the support block 16 to prevent the threaded block 12 from rotating.

[0032] Among them, motor 10 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0033] Working principle: In use, by pulling the control lever 17 through the handle 18, the clamping plate 6 is moved upward, and the bit is placed on the fixing ring 2. Then, the handle 18 is released. Due to the elasticity of the spring 4, the spring 4 applies elastic force to the clamping plate 6. The bit is clamped by the cooperation between the clamping plate 6 and 2, and it can accommodate bits of different sizes. At this time, the bit is softly fixed, and it can still be fixed within a certain range. The bit can be processed by spraying and other processes. When the bit needs to be hard fixed, the motor 10 on the support frame 9 drives the lead screw 11 to rotate. The threaded block 12 moves linearly on the lead screw 11 through the action of the thread. The threaded block 12 drives the clamping block 14 to slide through the fixing rod 13. The clamping block 14 slides to the connecting block 7 and connects with the slot 8 on the connecting block 7. Then it continues to slide downward, driving the clamping plate 6 to slide to clamp and fix the bit. At this time, the bit can be processed by cutting, grinding and other physical processes.
