Guide rods 803 are provided on the upper and lower sides of the ball screw 802. The guide rods 803 can guide the sliding seat 804. The sliding seats 804 are symmetrically connected to the outside of the ball screw 802 and the guide rods 803. The sliding seat 804 can drive the detection rod 805 to move. The detection rod 805 is fixed in the middle of the bottom end of the sliding seat 804. The detection rod 805 can detect the position of the mounting hole on the flange.

[0022] like Figure 1-Figure 2 As shown, the adjustment mechanism 3 includes a support shaft 301 fixed to the bottom end of the carrier 2, and the bottom end of the support shaft 301 is connected to an adjustment motor 302, so that the adjustment motor 302 drives the carrier 2 to rotate through the support shaft 301, thereby driving the flange to rotate.

[0023] like Figure 1-Figure 2 As shown, the fastening mechanism 4 includes two sets of fixing frames 401 , and the opposite sides of the two sets of fixing frames 401 are both arc-shaped structures, which facilitates clamping and fixing the flange through the fixing frames 401 .
