2. The utility model discloses keeping silent two and designing into inside sunken arc tooth mouth, the cavity that forms when utilizing two to keep silent the closure carries out the centre gripping to the lateral wall of parts such as pivot, and the tooth mouth of arc design is laminated with the side surface of pivot mutually, improves the clamping-force, and it is long when the reduction is dismantled.

Description of the drawings:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of a half-side clamp;

wherein: 1 half side clamp, 11 jaws, 111 straight section, 112 arc section, 113 arc tooth mouth, 12 clamp arms, 2 sliding impact components, 21 sliding hammer, 22 sliding hammer baffle, 3 sliding rod and 4 anti-slip layers.

The specific implementation mode is as follows:

as shown in fig. 1 and 2, the utility model relates to a shaft pin dismounting tool, include: the two-half-side pliers (1) comprise a jaw (11) and a plier arm (12) which are of an integral structure, and the two-half-side pliers (1) are mutually hinged in a crossed manner through a connecting shaft. The jaws 11 of the two half-side pliers 1 jointly form a pliers head, and the pliers arms 12 of the two half-side pliers 1 jointly form a pliers handle.

Each whole of keeping silent 11 is the arc, all includes straight section 111 and segmental arc 112, straight section 111 is located the top of keeping silent 11 for contact with the contact surface of fixed part, and the one end of straight section 111 passes through segmental arc 112 and links to each other with tong arm 12, has seted up a through-hole in segmental arc 112 and tong arm 12's juncture, and this through-hole is used for installing the connecting axle. An inwardly recessed arc-shaped tooth mouth 113 is formed on the end surface of the other end of the straight section 111, and the arc-shaped tooth mouth 113 is used for contacting with the side surface of a component such as a shaft pin. When the two jaws 11 are closed, the two arc-shaped tooth mouths 113 jointly enclose to form a cavity for clamping the shaft pin, and the stability when clamping the shaft pin is improved through the arc-shaped contact surfaces of the arc-shaped tooth mouths 113.

In order to disassemble, the shaft pin is easy to pull out, the disassembling tool also comprises a sliding impact assembly 2, a sliding rod 3 is arranged at the lower part of one half side clamp 1, one end of the sliding rod 3 is fixedly connected with a clamp arm 12 of the half side clamp 1, and the sliding rod 3, the circle center of a hinged point of the two half side clamps 1 and a cylindrical cavity are coaxially arranged.

The sliding impact assembly 2 is arranged on the sliding rod 3, the sliding impact assembly 2 comprises two sliding hammers 21 and two sliding hammer baffles 22, and one sliding hammer baffle 22 is fixed at the upper part of the sliding rod 3 and is used for generating impact force with the sliding hammers 21; another slide hammer retainer 22 is fixed to the lower portion of the slide bar 3 for preventing the slide hammer 21 from falling off the slide bar 3. The sliding hammer 21 is made of metal, is slidably sleeved on the sliding rod 3, and is located between the two sliding hammer baffles 22.

Further, the slide hammer baffle 22 is sleeved on the slide rod 3, and the slide hammer baffle 22 is any one of a circle, a square, an ellipse and a triangle.

Furthermore, the anti-slip layer 4 is arranged on the lower portion of each forceps arm 12, and the anti-slip layer 4 can increase the friction force when a user holds the forceps handle during clamping, so that the clamping stability is improved.

The working process is as follows:

when the tool is used, the straight sections 111 of the two jaws 11 are in contact with the contact surface of the fixed part, the arc tooth openings 113 on the two sides of the shaft pin are closed towards the shaft pin direction, the arc side walls of the arc tooth openings 113 clamp the side walls of the shaft pin after the arc tooth openings are closed, at the moment, a user holds the handle with one hand and slides the sliding hammer 21 with the other hand to enable the handle to slide towards the shaft pin direction, and the shaft pin is loosened by utilizing the vibration force generated when the sliding hammer 21 repeatedly impacts the sliding hammer baffle plate 22, so that the shaft pin is conveniently pulled out, the labor is saved, and the equipment part is not damaged.

The above description is only the preferred embodiments of the present invention, and these embodiments are all based on the present invention, and the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
