Technical Field

The invention relates to the field of clamping devices, in particular to an adjustable fire tongs.

background

The fire tongs comprise two parts, wherein the two parts comprise handles, tong shoulders and tong arms, and the two parts are mutually crossed, nested and movably connected at the tong shoulders. At present, the most common fire tongs are generally adopted to clamp the cylindrical sample for experiment when the heat treatment experiment is carried out, and the contact surface is small, the clamping force is limited, so that the sample is easy to drop in the clamping process, and the experiment effect is influenced.

through magnanimity retrieval, discover that the fire tongs among the prior art is like the fire tongs that publication number is CN105465838A discloses, including two articulated tong arms that are the X structure each other, the tong arm upper end is equipped with the handle, the tong arm lower extreme be provided with and be used for blocking the pothook of centre gripping thing in order to prevent the centre gripping thing landing, can provide an ascending holding power for the centre gripping thing through introducing the pothook, just so can reduce the clamp force between tong arm and the centre gripping thing to reduce user's the power of holding tightly, use like this and get up more easily, great degree has reduced simultaneously the fragile centre gripping thing and has been pressed from both sides garrulous risk. Or the duckbilled fire pliers disclosed by the publication number CN103128681A are provided with fire pliers handle main bodies, the front ends of the fire pliers handle main bodies are fire pliers rotating shafts, the front parts of the rotating shafts are arc-shaped jaws which can clamp thick forged pieces, and the foremost ends of the fire pliers handle main bodies are duckbilled jaws. The invention has wide application in the work of rural iron craftsmen, simple structure and high practicability. Or the fire-tongs disclosed by the publication number CN204366762U has the technical scheme that the fire-tongs comprise a fire-tongs body, wherein the fire-tongs body comprises two tong arms which are hinged with each other, the tong arms comprise a tong mouth and a handle, the hinged point is positioned between the tong mouth and the handle, an elastic part for driving the two handles to be folded is arranged between the two handles, the handle is provided with a convex block, an extrusion assembly is arranged between the convex blocks, a jet assembly is also arranged between the handles, the jet assembly comprises a water pipe, and the water pipe is communicated with the extrusion assembly; so that the folded fire tongs can spray a certain amount of water to the tongs mouth of the fire tongs to keep the fire tongs cool every time.

In conclusion, the fire tongs in the prior art have the problems that the adjustability is poor, the accessories cannot be freely replaced, the length cannot be adjusted according to the requirement and the like.

Disclosure of Invention

the present invention proposes an adjustable fire-tongs to solve the problems,

in order to achieve the purpose, the invention adopts the following technical scheme:

an adjustable fire tong comprises a first clamping arm and a second clamping arm which are symmetrically hinged, wherein the first clamping arm and the second clamping arm respectively comprise a handle, a tong shoulder, a tong arm, an adjustable rotary buckle and a clamping head which are sequentially connected; wherein the content of the first and second substances,

The adjustable rotary buckle is used for adjusting the clamping angle of the fire tongs;

the clamping head is used for clamping raw materials.

Furthermore, the adjustable rotary buckle comprises a first disc and a second disc, the first disc is connected to the tong arm, the second disc is connected to the clamping head, the first disc is rotatably connected with the second disc, a plurality of positioning holes are uniformly distributed in the first disc around the circle center, a matching hole matched with the positioning holes is formed in the second disc, and the positioning piece penetrates through the matching hole and the positioning holes to adjust the clamping angle of the fire tongs.

further, the clamping head is a circular clamping head.

Further, the clamping head is a saw-tooth circular clamping head.

Furthermore, the tong arm comprises a hollow arm, a clamping arm and a telescopic mechanism, the clamping arm is connected with the hollow arm through the telescopic mechanism, and the telescopic mechanism adjusts the length of the fire tongs by adjusting the telescopic effect of the clamping arm.

Furthermore, telescopic machanism includes spiral shell and spiral base, spiral base with the centre gripping arm links firmly, the spiral shell periphery is slick and sly, rotate connect in the cavity arm keeps away from articulated one end, thereby the spiral shell with the meshing of spiral part of spiral base realizes the centre gripping arm is flexible.

The beneficial technical effects obtained by the invention are as follows:

1. Through increasing adjustable rotatory knot, realized that different angles can all conveniently press from both sides and get the raw materials.

2. Through increasing on the clamping head increase sawtooth and can dismantle the change, realized not hindering the centre gripping and increasing frictional force to the raw materials.

3. The structure is convenient to process and low in maintenance cost.
