As shown in figure 1, the hand-operated valve comprises a valve body 1 and a valve cover 2 which is rotatably connected to the top end of the valve body 1. The horizontal sleeve 4 is connected to the outer side wall of the valve cover 2 in a threaded mode, and the limiting groove 5 along the length direction of the sleeve 4 is formed in the upper end face of the sleeve 4. The upper end opening of the limiting groove 5 penetrates through the upper side wall of the sleeve 4. One end of the sleeve 4, which is far away from the valve cover 2, exceeds the outer side wall of the valve cover 2, and a handle 3 used for controlling the rotation of the valve cover 2 is rotatably connected in the limiting groove 5 along the vertical direction.

As shown in fig. 2 and 3, the valve cap 2 is provided with a yielding groove 6 located right above the limiting groove 5, the yielding groove 6 is formed along the height direction of the valve cap 2, a lower end opening of the yielding groove 6 is communicated with the limiting groove 5, and an upper end opening of the yielding groove 6 penetrates through an upper side wall of the valve cap 2. The cross section of the abdicating groove 6 is arc-shaped, when the handle 3 is turned to a vertical state around the rotating shaft, the handle 3 is inserted into and limited in the abdicating groove 6, and the outer side wall of the handle 3 is attached to the abdicating groove 6. The limiting groove 5 is internally and fixedly bonded with a rubber pad 7 facing the yielding groove 6, and the rubber pad 7 is positioned below the handle 3 and close to the rotating shaft of the handle 3. The upper side wall of the rubber pad 7 is always in contact with the side wall of the handle 3.

As shown in fig. 1 and 2, three holding rods 11 are uniformly arranged at intervals on the part of the sleeve 4, which exceeds the outer side wall of the valve cover 2, and the three holding rods 11 are circumferentially arranged around the central axis of the sleeve 4. The side of the grip 11 away from the sleeve 4 is covered with a cover 12 made of rubber. The handle 3 is including the first body of rod 8 and the second body of rod 9, and the lower extreme of the first body of rod 8 is rotated and is connected in spacing groove 5, and the second body of rod 9 passes through threaded connection at the other end of the first body of rod 8, and the diameter of the first body of rod 8 is the same with the second body of rod 9. The end of the second rod 9 far from the first rod 8 is connected with a handle 10 by screw thread, and the maximum diameter of the handle 10 is larger than that of the second rod 9. When the first rod body 8 and the second rod body 9 are limited in the abdicating groove 6, the handle 10 is just positioned outside the abdicating groove 6. The outer side of the grip 10 is sleeved with an anti-slip sleeve 13, and anti-slip lines are uniformly arranged on the surface of the anti-slip sleeve 13 at intervals.
