[0007] Preferably, the first hook rod and the second hook rod are both placed on one side of the handle rod, and the second hook rod is placed below the first hook rod.
[0008] Preferably, a fluorescent strip is provided on the outer wall of the handle bar, and an adhesive layer is provided on the inner wall of the fluorescent strip. The fluorescent strip can be adhered to the handle bar through the provided adhesive layer, which can serve as a reminder.
[0009] Preferably, three groups of the fluorescent strips are provided, and the three groups of the fluorescent strips are distributed on the outer wall of the handle rod.
[0010] Preferably, a collar is provided on one side of the second hook rod, the collar is sleeved on the outer wall of the handle rod, and a screw is provided on the outer wall of the collar, and the screw is used to fix the position of the collar.
[0011] Preferably, an inner groove is provided on the inner wall of the collar, and a plurality of movable balls are evenly distributed inside the inner groove. The movable balls are provided to reduce the friction between the collar and the handle rod.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. By setting the handle rod, the first hook rod, the second hook rod, the lever arm storage slot, the movable lever arm and the fixing bolt, the movable lever arm is rotated to move the movable lever arm out of the lever arm storage slot and fixed with the fixing bolt, so that the force arm of the handle rod part becomes longer, and the lever principle can be used to pry a larger valve with a smaller force. The valve hook is also easy to fold by using screw connection. When the valve is relatively light, the movable lever arm can be bent back to the lever arm storage slot to form a common valve hook. When the valve is heavier, it is folded open, the lever arm becomes longer, and the switching is simple, so as to achieve the purpose of switching between the two modes. It can adapt to most commonly used valves and is relatively simple to operate.

The staff can hold the handle rod 11 and use the first hook rod 12 and the second hook rod 13 to rotate the valve. At the same time, the movable lever arm 14 is rotated to move the movable lever arm 14 out of the lever arm storage slot 111 and fixed with the fixing bolt 15, which will lengthen the force arm of the handle rod 11 part. The lever principle can be used to pry a larger valve with less force. The valve hook component 1 is also easy to fold by using screw connection. When the valve is relatively light, the movable lever arm 14 can be bent back to the lever arm storage slot 111 to form an ordinary valve hook component 1. When the valve is heavier, it can be folded open, the lever arm becomes longer, and the switching is simple, so as to achieve the purpose of switching between the two modes. The second hook rod 13 is placed on the outside of the handle rod 11 through the ring 131, and then fixed with a screw 132, so that the position of the second hook rod 13 is fixed, and it can be used in conjunction with the first hook rod 12. When the screw 132 is rotated in the opposite direction, the ring 131 can slide on the handle rod 11, thereby adjusting the distance between the first hook rod 12 and the second hook rod 13.
