1. Field of the Invention
The present invention relates to a hand tool, and more particularly to a pair of circlip pliers.
2. Description of Related Art
A conventional circlip plier is used to remove a circlip from a shaft or a tube. The circlip plier includes a pair of handles for holding and a pair of jaws respectively formed on the handles for clamping circlips. In order to remove an internal circlip or an external circlip, two different types of conventional circlip plier are provided, including an expanding type and a squeezing type. In normal state of the expanding type circlip plier, the jaws of the circlip plier are closed. When the expanding type circlip plier is in use, the handles of the circlip plier are pressed to each other and the jaws of the circlip plier are opened to expand an external circlip for removal from a shaft. Contrary to the expanding type circlip plier, the squeezing type circlip plier is used to squeeze an internal circlip to be removed from a tube.
However, the two different types of the circlip pliers are for different types of circlips, such that a user has to change between the different circlip pliers frequently for clamping different types of circlips and this is very inconvenient in use.
To overcome the shortcomings of the conventional circlip plier, the present invention provides a pair of circlip pliers to mitigate or obviate the aforementioned problems.
The main objection of the present invention provides a pair of circlip pliers having two operation states.
The complex circlip plier includes two handles, two jaws and two switching boards. The handles are symmetrical to a longitudinal axis and are arranged at a horizontal interval. The jaws are symmetrical in shape, are mounted between the handles, abut each other, and are pivotally connected with the handles. The switching boards are respectively and pivotally connected with the handles.
The pair of circlip pliers has two different operation states to allow a user to switch between the two states for different purposes.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The handles 10 are symmetrical to a longitudinal axis A and are arranged at a horizontal interval. Each handle 10 includes a griping portion 11 and an adjusting portion 12. A spring 111 is connected between the griping portions 11 of the handles 10. The adjusting portion 12 is a round plate, is formed on the top of the griping portion 11 and has a pivot hole 121, two sliding holes 122, a fixing hole 123 and a ring recess 124. The adjusting portions 12 of the handles 10 are arranged at a horizontal interval and a gap 120 is formed between the adjusting portions 12. The pivot hole 121 is formed though the adjusting portion 12. The sliding holes 122 are arc-shaped, are formed through the adjusting portion 12 and are respectively located at right and left sides of the pivot hole 121. The sliding holes 122 in each handle 10 correspond in position respectively to the sliding holes 122 in the other handle 10. The fixing hole 123 is formed through the adjusting portion 12 and located under the pivot hole 121. The ring recess 124 is formed around the pivot hole 121 and is located at an inner surface of the adjusting portion 12.
With reference to
The pivot unit 25 includes a screw 251 and a nut 252. The screw 251 is mounted through the through holes 210 of the jaws 20 and the pivot holes 121 of the handles 10. The nut 252 is screwed with the screw 251 to pivotally connect the jaws 20 with the handles 10.

Accordingly, the pair of circlip pliers can be applied for an expanding type circlip plier or a squeezing type circlip plier. A user can switch the switching boards 30 to connect one of the rods 24 of the jaws 20 and change the state of the pair of circlip pliers for different purposes so as to reduce the time of changing tools and the equipment cost.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
