A type E snap ring removal pliers

Abstract

This application discloses an E-type retaining ring removal pliers for removing E-type retaining rings. The E-type retaining ring is inserted into a fixed shaft. The pliers include a first clamp arm and a second clamp arm. A first blocking surface and a second blocking surface are respectively formed between the first clamp arm and the second clamp arm, which fit together. A rectangular cavity is formed at the bottom of the first blocking surface for the fixed shaft to pass through. Two blocking arms are formed on both sides of the rectangular cavity to abut against the two legs of the E-type retaining ring. The bottom of the second clamp arm abuts against the top surface of the E-type retaining ring, and the second blocking surface abuts against the side of the fixed shaft. This utility model uses the flat surface of one clamp head to abut against the pin as a force point, and the other open clamp head to abut against the open end of the E-type retaining ring. Then, by closing the clamp body, the E-type retaining ring can be easily removed.

Description

Technical Field

[0001] This application relates to pliers, and more particularly to a type E snap ring removal pliers. Background Technology

[0002] E-type snap rings are E-shaped metal fasteners installed in the grooves of mechanical shafts. Their unique stepped structure secures parts on the shaft, effectively limiting axial displacement. The cross-section of the E-type snap ring is stepped, with symmetrical openings at both ends forming an E-shape. The depth of the snap ring groove is interference-fitted with the shaft diameter.

[0003] Although E-type circlips are widely used, there are no corresponding professional disassembly tools on the market. Currently, the tools used are modified from C-type circlip pliers, which are difficult to disassemble and often require multiple attempts to remove. The main reason for this is that E-type circlips do not have ears with holes at the open end like C-type circlips, so that the needle-shaped pliers can be inserted for disassembly and assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a type E snap ring removal pliers. By using the flat surface of one pliers head to press against the pin as the force point, and the other open pliers head to press against the open end of the type E snap ring, the type E snap ring can be easily removed by closing the pliers.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] This application discloses an E-type retaining ring removal pliers for removing E-type retaining rings. The E-type retaining ring is inserted into a fixed shaft. The pliers include a first plier arm and a second plier arm. A first blocking surface and a second blocking surface are respectively formed between the first plier arm and the second plier arm. A rectangular cavity is formed at the bottom of the first blocking surface for the fixed shaft to pass through. Two blocking arms are formed on both sides of the rectangular cavity to abut against the two legs of the E-type retaining ring. The bottom of the second plier arm abuts against the top surface of the E-type retaining ring, and the second blocking surface abuts against the side of the fixed shaft.

[0007] Preferably, in the above-mentioned E-type snap ring removal pliers, the second clamp arm is slightly shorter than the first clamp arm.

[0008] Preferably, in the above-mentioned E-type snap ring removal pliers, when in use, the blocking arm abuts against the two legs of the E-type snap ring, the second clamping arm abuts against one side of the fixed shaft, clamping the first clamping arm and the second clamping arm, the fixed shaft passes through the rectangular cavity, and the E-type snap ring is pushed out of the fixed shaft.

[0009] Preferably, in the above-mentioned E-type snap ring remover, a horizontal cutting edge is formed at the bottom of the second clamp arm.

[0010] Preferably, in the above-mentioned E-type snap ring remover, a horizontal support surface is formed at the bottom of the first clamp arm.

[0011] Compared with existing technologies, the advantage of this technical solution is that the E-type retaining ring can be disassembled smoothly and conveniently, which is simple and efficient. Attached Figure Description

[0015] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Combination Figure 1-2 As shown, the E-type snap ring removal pliers 100 are used to remove the E-type snap ring 200, which is snapped into the fixed shaft 300. The pliers include a first clamping arm 101 and a second clamping arm 102. A first blocking surface 103 and a second blocking surface 104 are formed between the first clamping arm 101 and the second clamping arm 102, respectively, which fit together. A rectangular cavity 105 is formed at the bottom of the first blocking surface 103 for the fixed shaft 300 to pass through. Blocking arms 106 are formed on both sides of the rectangular cavity 105, abutting against two legs of the E-type snap ring 200. The bottom of the second clamping arm 102 abuts against the top surface of the E-type snap ring 200, and the second blocking surface 104 abuts against the side surface of the fixed shaft 300. The second clamping arm 102 is slightly shorter than the first clamping arm 101.

[0017] In use, the blocking arm 106 abuts against the two legs of the E-type retaining ring 200, the second clamping arm 102 abuts against one side of the fixed shaft 300, clamping the first clamping arm 101 and the second clamping arm 102, the fixed shaft 300 passes through the rectangular cavity 105, and the E-type retaining ring 200 is pushed out of the fixed shaft 300.

[0018] In this embodiment, the E-type retaining ring is disassembled smoothly by pressing the flat surface of one pliers head against the pin as the force point, and the other open pliers head against the open end of the E-type retaining ring, i.e., the two legs. Then, the pliers are closed.

[0019] Furthermore, a horizontal cutting edge 107 is formed at the bottom of the second clamp arm 102, and a horizontal support surface 108 is formed at the bottom of the first clamp arm 101.

[0020] In this embodiment, the horizontal cutting edge is positioned, and the horizontal support surface facilitates fitting and operation, making disassembly easier.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
