A turning support 2 is fixedly connected to the connecting base. A turning arm 3 is hinged to the turning support 2. A transition connecting seat 5 is fixed to the front end of the turning arm 3. Plug pin seats 8 are respectively connected to both sides of the transition connecting seat 5. A plurality of mounting holes are arranged at a certain interval along the height direction on the plug pin seats 8. Positioning guide sleeves 7 are connected in an interference fit in the mounting holes. A first positioning step surface 701 is provided at the rear end of the positioning guide sleeve. A plug pin 6 is inserted into the positioning guide sleeve from the rear end in a guiding manner. The head 601 of the plug pin protrudes from the rear end of the positioning guide sleeve.
