AI Technical Summary
The existing high-temperature clamping device requires workers to operate it with one hand during use. Over time, this can easily lead to hand fatigue and loosening, causing the container to fall and posing a safety hazard.
A high-temperature gripping device was designed, which uses two clamps arranged in a cross configuration. The clamping arms are connected to the rotating shaft, and the clamping parts and jaws are welded together. It is equipped with positioning springs and an anti-slip structure. The clamp handles are covered with heat insulation sleeves, and the wrists are evenly gripped by the positioning springs to prevent slippage and burns.
By evenly distributing the force on the hand, it reduces hand fatigue, securely holds the container, prevents it from falling, and improves safety during use.

[0016] Fig. 2 A partially enlarged structural schematic view of a high-temperature clamping device is proposed for the utility model;
[0017] Fig. 3 An exploded structural schematic view of a high-temperature clamping device is proposed for the utility model.
[0018] In the figure: 1, tongs body; 2, clamping arm; 3, rotating shaft; 4, clamping part; 5, mouth of tongs; 6, anti-skid convex part; 7, anti-skid convex strip; 8, handle; 9, fixed pin; 10, positioning spring; 11, heat insulation sleeve; 12, protective sleeve. DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0020] REFERENCE Figs. 1-3 A high-temperature clamping device, comprising two tongs bodies 1, one end of the tongs body 1 is welded with a clamping arm 2, the two clamping arms 2 are crossly arranged, the intersection of the two clamping arms 2 is inserted with a rotating shaft 3, the other end of the clamping arm 2 is welded with a clamping part 4, the clamping part 4 is V-shaped structure, the other end of the clamping part 4 is welded with a mouth of tongs 5, the other end of the tongs body 1 is welded with a handle 8, the positioning spring 10 is arranged between the two handles 8, the hand is passed between the positioning spring 10 and the handle 8, so that the positioning spring 10 is sleeved on the wrist part of the operator, the wrist part will be stressed during operation, then the fingers are pinched on the handle 8, so that the hand and the wrist part are uniformly stressed during clamping, the fixed pin 9 is inserted between one end of the positioning spring 10 and the inner side of the handle 8.
[0021] The inner side of the clamping part 4 is integrally formed with anti-skid convex strips 7, so as to prevent slipping when the clamping part 4 is clamped; the inner side of the jaw 5 is integrally formed with anti-skid convex parts 6, so as to prevent slipping when the jaw 5 is clamped; the positioning elastic sheet 10 is in a C-shaped structure; the outer wall of the handle 8 is sleeved with a heat insulation sleeve 11, so as to avoid temperature transmission to the handle 8, thereby preventing scalding of the hand; the outer wall of the positioning elastic sheet 10 is sleeved with a protective sleeve 12, so as to protect the wrist when clamping, thereby preventing damage to the wrist.
[0022] The working principle of the embodiment is as follows: before clamping, the clamping part 4 and the jaw 5 need to be preheated, so as to prevent the clamping part 4 and the jaw 5 from contacting cold vessels, thereby preventing the vessels from being broken; then, the hand is passed between the positioning elastic sheet 10 and the handle 8, so as to sleeve the positioning elastic sheet 10 on the wrist of the operator; the wrist is stressed during operation; then, the fingers are pinched on the handle 8, so that the hand and the wrist are uniformly stressed during clamping; then, the fingers are opened, so that the handle 8 is opened outward, so that the clamping arm 2 is opened outward, and then the clamping part 4 and the jaw 5 are opened outward; at this time, the positioning elastic sheet 10 is stretched outward; then, the clamping part 4 or the jaw 5 is selected according to the clamping requirement, so as to clamp the vessels between the two clamping parts 4 or the two jaws 5; then, the handle 8 is pinched inward, so that the clamping arm 2, the clamping part 4 and the jaw 5 are rotated inward, so as to clamp the vessels tightly; at the same time, the positioning elastic sheet 10 is stretched, so as to assist the clamping arm 2, the clamping part 4 and the jaw 5 to close together, thereby assisting the clamping of the vessels, and then stably clamping the vessels.
