Disassembly and assembly pliers for automobile drive shaft dust collar

The present invention relates to a maintenance tool for an automobile, and more particularly to a disassembly and assembly pliers for a dust-collecting ring of an automobile transmission shaft. When the dust cover of the automobile transmission shaft is installed or removed, the disassembly and assembly pliers are used for the bundle ring. Remove from the boot or attach the collar to the boot.

The two transmission shafts of the automobile are connected by a universal joint. In order to avoid the contamination of the universal joint by mud, gravel, water and other foreign materials from the ground, the smooth operation of the universal joint is affected, and the universal joint is disposed outside the universal joint. A dust jacket made of rubber, the dust jacket is similar to the tubular body of the snake tube, and the two ends of the dust jacket are respectively sleeved on the outer circumference of the two transmission shafts, and the outer circumferences of the two ends of the dust jacket respectively bundle a bundle ring to thereby locate The dust jacket prevents the dust jacket from slipping off.

As shown in the first figure and the second figure, the bundle ring that is sleeved on the outer periphery of the two ends of the dust jacket is composed of a belt body (1) made of an elastic metal plate, and the two ends of the belt body (1) are relatively curved. In a ring shape, the belt body (1) comprises a first segment (11) and a second segment (12), the first segment (11) is adjacent to one end of the strip body (1), and the second segment (12) Adjacent to the other end of the strip body (1), the first segment (11) is adjacent to the outer side of the second segment (12), and the first segment (11) extends through a first recess (13) and a second recess a first protrusion (15) protrudes outward from the slot (14), and the second slot (14) is formed between the first slot (13) and the first protrusion (15) And the first slot (13) is adjacent to the end of the first segment (11), and the second segment (12) protrudes outwardly from a second protrusion (16), a first button portion (17), and a first portion a second buckle portion (18), and the second convex portion (16) is adjacent to the end of the second segment (12), and the second buckle portion (18) is formed on the second convex portion (16) and the first buckle portion (17) It between.

When the bundle of the collar is sleeved on the dust jacket, the first fastening portion (17) protrudes from the outer side of the first segment (11) through the first fitting groove (13), and the second fastening portion (18) and the second convex portion (16) ) protruding through the second recess (14) outside the first segment (11), the material of the strip (1) is elastic, so that the first buckle (17) and the first recess (13) are adjacent to the first segment (11) The groove wall of the end is abutted, and the second buckle portion (18) and the second groove (14) abut against the groove wall at the end of the first segment (11), and the first convex portion (15) and the first portion The two convex portions (16) are opposed to each other, whereby the second segment (12) is fastened to the first segment (11) by the first fastening portion (17) and the second fastening portion (18).

When the collar is to be mounted on the outer circumference of the dust jacket, the belt body (1) is looped around the outer circumference of the dust jacket, and the first segment (11) is placed against the second segment (12), and the second convex portion (16) is passed. The second recess (14) protrudes outside the first segment (11), a clip of the needle-nosed pliers abuts against one end of the first protrusion (15), and the other clip abuts against the second protrusion (16) At one end, the needle-nosed pliers are operated so that the respective clips are relatively clamped against the first convex portion (15) and the second convex portion (16), so that the first segment (11) and the second segment (12) are relatively slipped, and Pressing the first segment (11) from the outside to the inside, so that the first fastening portion (17) and the second fastening portion (18) protrude from the first segment through the first slot (13) and the second slot (14) (11) External, and then, the clamping of the first protrusion (15) and the second protrusion (16) by the respective clips is released, and the material elasticity of the strip (1) causes the first segment (11) and the second segment (12) reverse sliding, until the first fastening portion (17) abuts against the groove wall of the first fitting groove (13), and the second fastening portion (18) abuts against the groove wall of the second fitting groove (14), Installation of the collar.

When the tow ring mounted on the dust jacket is to be removed, the first convex portion (15) and the second convex portion (16) are relatively opposed by the needle-nosed pliers, so that the first segment (11) is opposite to the second segment (12). Sliding, releasing the first buckle portion (17) and the second buckle portion (18) from the groove walls of the first fitting groove (13) and the second fitting groove (14), respectively, due to the belt body (1) The first buckle portion (17) and the second buckle portion (18) are respectively ejected from the first recessed groove (13) and the second recessed groove (14), and the second segment (12) is released from the first segment ( 11) status, completed The removal of the loops, and then the clamping of the first projections (15) and the second projections (16) by the respective clips is released, and the second projections (16) are then withdrawn from the second recesses (14).

Since the belt body (1) is made of elastic metal sheets, when the bundle ring is mounted and removed, the respective jaws of the needle-nosed pliers are easily slid relative to the first convex portion (15) and the second convex portion (16). Therefore, it is difficult for each of the clamps to effectively hold against the first convex portion (15) and the second convex portion (16), and the attachment and removal operations of the bundle ring are not easily performed.
