Description
Technical Field
The utility model relates to a double-end retainer ring clamp, and belongs to the technical field of hand tools.
Background
The retainer ring is also called a snap spring, is a fastener used for axially positioning, locking or stopping the parts on the shaft or the hole, and can prevent the parts on the shaft or the hole from axially moving. The retainer rings are classified into two main types, namely an outer retainer ring (conventionally also referred to as a retainer ring for a shaft) applied to the shaft and an inner retainer ring (conventionally also referred to as a retainer ring for a hole) applied to the hole according to the use scene.
The retainer clip (also referred to as a clip) is a tool used when installing a retainer, and generally includes an outer retainer clip for installing an outer retainer and an inner retainer clip for installing an inner retainer. When the outer retainer ring is installed, the outer retainer ring needs to be enlarged by using an outer retainer ring clamp, namely, a clamp mouth is inserted into a clamp hole of the outer retainer ring to expand the retainer ring, and then the retainer ring is placed into a pre-processed shaft groove; when the inner retainer ring is installed, the diameter of the inner retainer ring needs to be clamped to be small by using inner retainer ring pliers, and then the inner retainer ring is installed in a preset hole.
However, when the outer check ring and the inner check ring are installed at present, different check ring pliers are required to be used respectively, the carrying and the use are inconvenient, and particularly in certain cases, the outer check ring and the inner check ring are required to be frequently switched and installed, so that the use is more troublesome.
