During the processing of the air duct, fine comparison and processing can be performed based on the image after BIM modeling, and the air duct can be clamped by a processing jig and its outer side can be finely processed. However, after the processing jig in the prior art clamps the air duct during use, the processing angle of the air duct is not easy to adjust, which affects the practicality of the device. After the air duct is squeezed and clamped by threaded matching, the vibration generated by fine processing can easily cause the clamping to be sent, affecting the stability of the processing. Therefore, it is necessary to improve the prior art. Utility Model Content

[0006] Preferably, the threaded frame is slidably connected to the base, and the threaded frame is connected to the screw rod via threads, and the threaded frame can drive the movable frame to move by cooperating with the threads of the screw rod.

[0007] Preferably, the adjustment limit mechanism includes a limit gear, the limit gear is fixedly connected to the outer side of the connecting shaft of the fixed support seat, a fixed cover is fixedly connected to the lower part of the vertical surface of the right end of the fixed frame, a pull ring rod is slidably connected to the inside of the fixed cover, a fixed ring is fixedly connected to the middle part of the outer side of the pull ring rod, the upper end of the pull ring rod is fixedly connected to a tooth block, and a spring is arranged on the outer side of the pull ring rod, and the pull ring rod can drive the tooth block to move.

[0008] Preferably, one end of the spring is fixedly connected to the fixing cover, and the other end of the spring is fixedly connected to the fixing ring, and the spring can support the fixing ring through elastic force.

[0009] Preferably, the tooth block is slidably connected to the tooth groove of the limiting gear, and the fixing ring is slidably connected to the inner wall of the fixing cover, and the tooth block can limit the limiting gear.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model adds a fixed cover, a tooth block, a spring and other structures on the fixed frame. During use, the fixed support seat and the movable support seat can be rotated to adjust the processing angle of the air duct. When the angle adjustment is completed, the elastic force of the spring can push the tooth block to slide into the tooth groove of the limiting gear on the outer side of the fixed support seat to limit the air duct, thereby making the processing angle of the air duct easier to adjust.

[0012] 2. The utility model adds a resistance ring on the outside of the hand wheel.
