Detailed Description

The following detailed description of the embodiments according to the present utility model is provided with reference to the preferred embodiments: referring to the drawings in detail, this embodiment provides a valve clamping forceps, including first arm 1 and second arm 2 and binding clip 3, rivet pivot 4 and ring handle 5, the middle section of first arm and second arm is articulated with rivet pivot mutual riveting, and inlay 7 that the front end of first arm and second arm had the binding clip, the rear end is equipped with the ring handle, the forearm of first arm and second arm is equipped with bending angle 6 along its arm trailing arm straight line direction respectively, constitutes the usage space that exposes the operation position, the binding clip is right angle relative setting with first arm or second arm front end respectively, constitutes after the binding clip is closed and presss from both sides the valve inlay.

In a preferred embodiment of this embodiment, the bending angles of the forearms of the first and second jawarms are respectively set in two directions, i.e., left and right.

In a preferred embodiment of this embodiment, the angles between the axes of the bent portions of the front arms of the first and second jawarms and the axes of the rear arms of the first and second jawarms in the straight directions thereof are 13 °,15 °,18 ° and 23 °, respectively.

In a preferred scheme of the embodiment, the total length of the clamp body is 250-255mm.

In the preferred scheme of the embodiment, the front end head of the clamp head is provided with a zigzag holding opening 3-1, and the holding openings of the first clamp arm and the second clamp arm are mutually meshed when the clamp head is closed.
