An internal combustion engine fuel regulating valve lock cap wrench

Abstract

This utility model discloses a locking cap wrench for an internal combustion engine gas regulating valve, including a connecting seat. A wrench head is movably connected to the right side of the connecting seat, and an adjusting groove is provided on the right side of the wrench head. The center line of the wrench head and the center line of the connecting seat are on the same horizontal plane. This locking cap wrench for an internal combustion engine gas regulating valve, by providing connecting cylinders, allows the wrench to be used by pulling a movable baffle to move it to one side, disengaging it from between two sets of connecting cylinders. This allows the two sets of connecting arms to be pulled to unfold for easy rotation and adjustment. After use, the movable baffle can be pulled again to disengage it from between the connecting cylinders, and the two sets of connecting arms can be pulled to fold it. Finally, a first spring pushes the movable baffle out, causing it to fit between the two sets of connecting cylinders and onto the outer plane of the connecting cylinders. The connecting cylinders can position the connecting arms, solving the problem of inconvenient folding and storage.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, when using this wrench, pull the movable baffle 10 to move it to one side, so that it is separated from the two sets of connecting cylinders 2. Then, pull the two sets of connecting arms 3 to unfold it for easy rotation and adjustment. After use, pull the movable baffle 10 again to separate it from the connecting cylinders 2, and then pull the two sets of connecting arms 3 to fold it. Finally, the first spring 11 pushes the movable baffle 10 out so that it fits between the two sets of connecting cylinders 2 and fits on the outer plane of the connecting cylinders 2. The connecting arms 3 can be positioned by the connecting cylinders 2, which makes it easy to fold and store.

[0030] A connecting arm 3 is fixedly connected to the left side of the connecting cylinder 2. A movable arm 4 is movably connected to the outside of the connecting arm 3. A rubber pad 6 is fixedly connected to the outside of the movable arm 4. Positioning holes 7 are opened on both sides of the movable arm 4.
