Through the connecting rod mounting seat 16 and the two connecting rods 17, the left leg 12 and the right leg 13 are synchronously supported outward at an angle.

[0051] The support assembly 2 includes a main rod assembly 21, an armrest 22 and an electric push rod 23; the main rod assembly 21 is fixedly connected to the base 11 and tilted backward, the boom 3 is hinged at the top of the main rod assembly 21, and the main rod assembly 21 also has an electric control group 24; the armrest 22 is U-shaped and fixedly connected to the upper part of the main rod assembly 21, and the armrest 22 is provided with a hand controller 25 electrically connected to the electric control group 24; the electric push rod 23 is movably hinged between the lower part of the main rod assembly 21 and the rear part of the boom 3.

[0052] The main rod assembly 21 includes a main rod sleeve 211 and a main rod body 212. The main rod sleeve 211 is fixed at the middle position of the base 11. The lower part of the main rod body 212 is slidably embedded in the main rod sleeve 211. The main rod body 212 is fixed in the main rod sleeve 211 by a fastening and locking structure.

[0053] During use, the connection between the main rod body 212 and the base 11 will be subjected to greater stress, because the main rod body 212 is installed and fixed by the main rod sleeve 211, which can increase the strength of the connection between the two, disperse the stress, and make the main rod body 212 not easy to bend.

[0054] The fastening and locking structure includes a double-step screw 26. Through holes suitable for the double-step screw 26 to pass through left and right are provided on the main rod body 212 and the main rod sleeve 211. The two ends of the double-step screw 26 are connected to the first knob 27. By tightening the first knob 27, the main rod body 212 is fixed in the main rod sleeve 211; however, there will inevitably be a gap between the main rod body 212 and the main rod sleeve 211, that is, after being locked by the double-step screw 26, the main rod body 212 may swing back and forth along the double-step screw 26 as the central axis. Therefore, the fastening and locking structure also includes a second knob 28. The threaded rod of the second knob 28 passes through the main rod sleeve 211 and is locked and connected to the main rod body 212, thereby limiting the swinging of the main rod body 212 back and forth.

[0055] In more embodiments, the main rod body 212 can also be fixed in the main rod sleeve 211 through a sliding locking structure, and the main rod body 212 can be extended and retracted up and down relative to the main rod sleeve 211 through a dynamic locking structure, thereby adjusting the height of the net bag.
