Example 1

Referring to fig. 1 to 3, a novel crucible tool comprises a crucible 1 and a crucible tongs 2.

The crucible 1 comprises a crucible body 12 and a hanging ring 13 arranged on the side wall of the crucible body 12, wherein a vertical through hole 14 is formed in the hanging ring 13.

The crucible tongs 2 comprises a clamping groove part 21, a butting part 22 and a handheld part 23 which are connected in sequence. The clamping groove part 21 is used for clamping a part of structure into the vertical through hole 14, and is matched with other structures of the clamping groove part 21 to clamp and support the hanging ring 13.

The abutting portion 22 is connected between the clamping groove portion 21 and the holding portion 23, the abutting portion 22 has an arc-shaped section which is bent towards the crucible body 12, so that when the abutting portion 22 supports the clamping groove portion 21 to be clamped on the hanging ring 13, the arc-shaped section of the abutting portion 22 abuts against the side wall of the crucible body 12.

The hand-held portion 23 is a rod-shaped structure extending in the horizontal direction. The hand-held portion 23 is provided with a frosted anti-slip layer on the portion held by the user's hand, which in other embodiments is a square rod-shaped structure, or other rod-shaped structure with a polygonal cross-section.

In the crucible tool, the hanging ring 13 is arranged on the side wall of the crucible body 12, the vertical through hole 14 is arranged on the hanging ring, and the crucible is moved by utilizing the clamping groove part 22 of the crucible tongs in the design to clamp and support the hanging ring 13. This moving means is simple and convenient, and the bayonet socket part 21 bearing strength and the top 21 of mainly relying on crucible tongs 2 support the crucible with crucible body 12 to support the crucible mutually, thereby change and now utilize frictional force to press from both sides the mode of getting the crucible, thereby avoid pressing from both sides the dynamics of getting, press from both sides the direction, or crucible tongs and crucible contact surface reason such as smooth because of pressing from both sides, lead to pressing from both sides the frictional force and be less than the crucible dead weight and make the crucible fall. Therefore, the novel crucible tool kit is used, and the technical problem that the friction force is smaller than the self weight of the crucible and the crucible falls off due to the fact that the existing crucible tongs bring about clamping is solved by adopting a new technical means.

Referring to fig. 3, the slot portion 21 includes a first vertical rod 24, a bottom slot 25 and a second vertical rod 26. The first vertical rod 24 is matched with the vertical through hole 14, and the U-shaped groove of the clamping groove part 21 is matched with the side wall of the outer side of the vertical through hole 14 of the hanging ring 13. Therefore, the clamping groove part 21 can be well clamped into the hanging ring 13 and is matched with the hanging ring 13 in a stable clamping and bearing way.

In order to further ensure the stability of the crucible tongs 2 for supporting the crucible 1, the vertical thickness of the hanging ring is preferably 1.5 CM-5 CM. In this embodiment, the vertical thickness of the suspension loop is 3 CM.

Referring to fig. 3, the first vertical rod 24 is a trapezoid structure gradually widening from top to bottom toward the second vertical rod 26, and the vertical through hole 14 is a trapezoid structure adapted to the first vertical rod 24. The trapezoidal structure enables the first vertical rod 24 to be embedded into the vertical through hole 14 more conveniently and quickly.

Embodiment 2 as shown with reference to figure 4,

the embodiment of the present invention provides a device, which has the same technical effects as those of embodiment 1, and for the sake of brief description, the embodiment does not mention, and reference can be made to the corresponding contents of embodiment 1.

In this embodiment, in order to make the crucible tongs 2 held by the user more stable, a hook-shaped section bent upward is disposed at the lower end of the arc-shaped section of the abutting portion 22, and the other end of the hook-shaped section is connected to the holding portion 23.

Through the hook-shaped section, the height position of the handheld part 23 is similar to the propping position of the propping part 22, so that the force application is more stable and labor-saving. So that the user can hold the crucible tongs 2 more stably.

Furthermore, in order to prevent the abutting part 22 of the crucible tongs 2 from moving left and right relative to the crucible body 12, the stability is affected. In this embodiment, an arc-shaped retaining piece 27 is disposed at a position of the abutting portion 22, which abuts against the side wall of the crucible body 12, and an arc surface of the arc-shaped retaining piece 27 is matched with the outer side wall of the crucible body.

Example 3, see figure 5.

The embodiment of the present invention provides a device, which realizes the same technical effects as those of embodiment 2, and for the sake of brief description, the embodiment does not mention, and refer to the corresponding contents of embodiment 2.

In order to prevent the abutting part 22 of the crucible tongs 2 from moving left and right relative to the crucible body 12, the stability is affected. In this embodiment, a clamping structure 15 is convexly arranged on the outer side wall of the crucible body 12, and the clamping structure 15 is used for clamping the left and right moving space of the abutting portion 22 when the abutting portion 22 abuts against the crucible body 12.

Referring to fig. 5, in the present embodiment, the retaining structures 15 are two hemispheres protruding from the outer sidewall of the crucible body 12 at intervals. In other embodiments, the retaining structures 15 are two cylinders protruding from the outer side wall of the crucible body 12 at intervals.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
