[0021] The bottom end of the chuck key 3 extends into the slot 208 on the driving block 207. Rotating the chuck key 3 drives the rotating disk 201 and the screw 209 to rotate. The screw 209 limits the rotating disk 201. The clamping rod 204 moves toward the driving block 207 along the direction of the guide rail 206 through the arc groove 202, and the clamping rod 204 clamps and fixes the chuck key 3.

[0022] like Figure 2-3 As shown, the outer side of the clamping rod 204 is covered with a plurality of rubber blocks. When the clamping rod 204 contacts the chuck key 3 , the rubber particles on the clamping rod 204 can enhance the firmness of fixing the chuck key 3 .

[0023] like Figure 3 As shown, the upper and lower ends of the limit block 205 are respectively installed with limit plates, and the two limit plates are respectively arranged at the upper and lower ends of the guide rail 206. The limit plates at the upper and lower ends of the limit block 205 cooperate with the guide rail 206 to limit the clamping rod 204.

[0024] like Figure 2 As shown, a sensing block is installed on the lower part of the outer side of the chuck key 3, a sensing switch 4 is installed on the inner side of the shell 1 and at the same horizontal plane as the sensing block on the chuck key 3, and a relay control module 5 is installed on the inner side of the shell 1 near the bottom. When the sensing block on the chuck key 3 is close to the sensing switch 4, the sensing switch 4 sends an electrical signal to the relay control module 5, and the signal outputs an on-off signal through the relay control module 5, and the on-off signal controls the start of the chuck.

[0028] When in use, the housing 1 is installed in a position convenient for installing the chuck key 3. When the chuck key 3 is used to adjust the chuck, the sensing block on the chuck key 3 is away from the sensing switch 4, the sensing switch 4 sends an electrical signal to the relay control module 5, and the relay control module 5 outputs a signal to turn off the drive of the chuck, and the chuck key 3 is inserted into the card slot 208 on the drive block 207 for rotation, and the drive block 207 drives the rotating disk 201 to rotate. When the rotating disk 201 rotates, the screw 209 is threadedly connected with the fixing hole at the bottom end of the mounting cavity on the housing 1, thereby limiting the rotating disk 201. When the rotating disk 201 rotates, the clamping rod 204 is driven to move by the moving rod 203, and the clamping rod 204 moves along the direction of the guide rail 206 through the limit block 205, and the clamping rod 204 clamps the chuck key 3, and the sensing block on the chuck key 3 is close to the sensing switch 4, and the sensing switch 4 sends an electrical signal to the relay control module 5, and the relay control module 5 sends an on-off signal to control the start of the chuck.
