The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0040] In the specific use of this embodiment, when the tool 64 needs to be adjusted, the electric push rod 82 is first started through the external PLC, and the piston rod movement of the electric push rod 82 drives the connecting plate 83 fixed to it through the gasket 84 to move, and the movement of the connecting plate 83 drives the installation plate 2 fixed to it to move, and the installation plate 2 moves under the guidance of the two slide bars 5 and the two slide grooves on the top surface of the working plate 1.

[0041] Then, the tool setting instrument body 3 and the motor 78 are started through the external PLC, and the output shaft of the motor 78 is controlled to rotate alternately in positive and negative directions. The rotation of the output shaft of the motor 78 drives the rotating shaft 79 coaxially connected thereto to rotate. The rotation of the rotating shaft 79 drives the coaxially fixed gear 77 on the same side to rotate. The rotation of the gear 77 drives another gear 77 meshing therewith to rotate. The rotation of the other gear 77 drives the rotating rod 76 coaxially fixed therewith to rotate. The rotation of the rotating rod 76 drives the coaxially fixed rotating column 72 on the same side to rotate. The rotation of the rotating column 72 drives the coaxially fixed The screw rod 73 rotates because the output shaft of the motor 78 rotates alternately forward and reverse, thereby making the screw rod 73 rotate alternately forward and reverse. The screw rod 73 rotates alternately forward and reverse, thereby making the connecting rod 74 perform linear reciprocating motion. The connecting rod 74 moves under the guidance of the guide block 75 and the guide groove on the top surface of the mounting plate 2. The movement of the connecting rod 74 drives the tool setting instrument body 3 and the tool setting probe 4 to move.
