Embodiment 1

[0029] An adjustable fire tongs, comprising a symmetrically hinged first clamp arm and a second clamp arm, the first clamp arm and the second clamp arm both include a handle 1, a pincer shoulder 2, a pincer arm 3, and an adjustable rotary buckle 4 sequentially connected , and the clamping head 5; wherein,

[0030] The adjustable rotary buckle 4 is used to adjust the clamping angle of the tongs;

[0031] The clamping head 5 is used for clamping raw materials.

[0032] The adjustable rotary buckle 4 includes a first disc 401 and a second disc 402, the first disc 401 is connected to the pliers arm 3, and the second disc 402 is connected to the clamping head 5, the first disc 401 is rotatably connected to the second disc 402, and the first disc 401 is uniformly distributed with a number of positioning holes 403 around the center of the circle, and the second disc 402 is opened with The positioning hole 403 is matched with the matching hole, and the positioning piece 404 passes t...

Embodiment 2

[0037] An adjustable fire tongs, comprising a first clamp arm and a second clamp arm which are arranged symmetrically and hinged by rivets. Adjust the rotary buckle 4 and the clamping head 5; wherein,

[0038] The adjustable rotary buckle 4 is used to adjust the clamping angle of the tongs;

[0039] The clamping head 5 is used to clamp raw materials;

[0040] The two tong shoulders 2 are intersected and hinged by rivets, one of which is a flat part for the rotating part of the tong shoulder, and the rest are raised, which can achieve a certain rotation limit and the raised part can well improve the overall strength of the tongs; Another solution in the embodiment is that the two pliers shoulders 2 are intersected and nested with each other and are movably connected by rivets, so that they can flexibly rotate around the rivet hinge;

[0041] The symmetrical design allows the user to hold and place the tongs at will regardless of the front and back when using the tongs, which ...

Abstract

The invention provides a pair of adjustable tongs. The pair of adjustable tongs comprises a first clamping arm and a second clamping arm which are symmetrically hinged. The first clamping arm and thesecond clamping arm each comprise a handle, a tongs shoulder, a tongs arm, an adjustable rotary buckle and a clamping head which are connected in sequence, wherein the adjustable rotary buckles are used for adjusting the clamping angle of the tongs, and the clamping heads are used for clamping raw materials. By adding the adjustable rotary buckles, the materials can be conveniently clamped at different angles; by adding detachable sawteeth to the clamping heads, the damage-free clamping of the raw materials is realized, and friction force is increased; and moreover, the pair of adjustable tongs is simple in structure, convenient to machine and low in maintenance cost.

Description

technical field [0001] The invention relates to the field of clamping devices, in particular to an adjustable fire tongs. Background technique [0002] The fire tongs are composed of two parts, both of which are composed of a handle, a tong shoulder, and a tong arm, and the two parts are nested and flexibly connected to each other at the tong shoulder. At present, when conducting heat treatment experiments, the most common tongs are generally used to clamp cylindrical samples for experiments. Due to the relatively small contact surface and limited clamping force, it is easy to cause the sample to fall during the clamping process, thus affecting the experiment. Effect. [0003] After a large number of searches, it was found that the fire tongs in the prior art, such as the fire tongs disclosed by the publication number CN105465838A, include two pincer arms hinged to each other in an X structure, the upper end of the pincer arm is provided with a handle, and the lower end of ...
