[0025] Specifically, if Figures 1 to 3 As shown, the locking device of the upper anvil 2 includes three parts: mechanical, hydraulic and electrical. The mechanical part includes the latch 9, the locking rod 4, the positioning key 23, etc. The movement of the mechanical parts is driven by the hydraulic system, the actuator is the oil cylinder, and the input and output of the hydraulic system and the signal are controlled electrically.

[0026] like Figures 1 to 3 As shown, the driving mechanism is installed on the movable crossbeam 6, and the moving direction of the latch 9 is perpendicular to the moving direction of the locking rod 4. A driving surface 7 is provided on the latch 9, and a matching surface 8 in contact with the driving surface 7 is provided on the locking rod 4. The driving surface 7 is a plane that is inclined relative to the moving direction of the latch 9. The driving surface 7 is located at one end of the length direction of the latch 9, and there is an angle between the length direction of the driving surface 7 and the moving direction of the latch 9, and the angle is an acute angle. The latch 9 is horizontally arranged. When the latch 9 moves, the latch 9 pushes the locking rod 4 to move linearly upward in the vertical direction through the driving surface 7, and the locking rod 4 drives the upper anvil 2 to move synchronously until the upper anvil 2 is moved to the installation position that fits the movable crossbeam 6. At this time, the upper anvil 2 can be locked and fixed on the movable crossbeam 6.

[0027] like Figures 1 to 3 As shown, the locking rod 4 is provided with a socket 22 for the insertion of the plug 9, the socket 22 is a waist-shaped hole, and the front end surface of the plug 9 is processed into a waist shape. During operation, the waist-shaped front end of the plug 9 matches with the waist-shaped hole of the locking rod 4. The matching surface 8 is located at the top of the socket 22, and the socket 22 is vertically arranged on the locking rod 4. The matching surface 8 is an inclined plane, and there is an angle between the length direction of the matching surface 8 and the horizontal direction, and the angle is an acute angle. The plug 9 is inserted into the locking rod 4, and the driving surface 7 matches with the matching surface 8. The locking rod 4 is tightened by the matching of the inclined surface, and then the upper anvil 2 is locked on the movable crossbeam 6 through the locking rod 4.

With this design, the installation position of the proximity switch 17 can be easily adjusted to adapt to different working environments and requirements.
