[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3As shown in the embodiments of this specification, a gripping device for a liquid nitrogen storage system is disclosed, including a gripping assembly 1, a connecting tube assembly 2, and a handle 3. One end of the gripping assembly 1 is detachably connected to the connecting tube assembly 2, and the other end of the connecting tube assembly 2 is connected to the handle 3. Squeezing the handle 3 controls the opening and closing of the gripping assembly 1. The gripping assembly 1 includes multiple replaceable gripping heads for gripping different types of materials. Selecting appropriate gripping heads according to different types of materials can prevent materials from falling out during gripping, thereby improving gripping efficiency.

[0024] The gripping head includes a first gripping head 1.1, the front end of which is provided with a flat gripping part for gripping box-shaped materials.

[0025] The connecting tube assembly 2 includes multiple replaceable tube assemblies of different lengths. By changing the tube assemblies of different lengths, materials inside liquid nitrogen containers at different heights can be gripped, avoiding situations where the connecting tube assembly 2 is too short to grip the material. The connecting tube assembly 2 can also adopt a telescopic wire drawing mechanism widely used in the prior art to achieve the conversion between connecting tube assemblies of different lengths.

[0026] The end of the connecting tube assembly 2 near the handle 3 is detachably connected to a lighting device 4. The lighting device 4 enables the device to clearly grip materials even in low light conditions, improving the applicability of the device. It eliminates the need for artificial lighting and is easy to use.

[0027] The lighting device 4 is fixedly mounted on the connecting pipe assembly 2 by a snap fastener. The position of the snap fastener can also be adjusted according to the actual situation to change the position of the lighting device 4 and ensure clear clamping.

[0028] The lighting device 4 is preferably a flashlight, but other lighting devices widely used in existing technologies, such as small light bulbs, can also be used.

[0029] The gripping head includes a second gripping head 1.2, which has a curved gripping part. The curved gripping part has a serrated structure and is used to grip tubular materials. The serrated structure can increase the friction between the gripping part and the material, and prevent the material from falling off during the gripping process.

[0030] The serrated structure is equipped with anti-slip textures, which further increase the friction between the gripping part and the material, thereby improving the friction effect and preventing the material from falling off during the gripping process.

[0031] The pressing part of the handle 3 is provided with anti-slip protrusions. The anti-slip protrusions are round in shape. This design can increase the friction between the operator's fingers and the handle 3, and prevent the operator from slipping while squeezing the handle 3, which would cause the material to fall.

[0032] The gripping head includes a third gripping head 1.3, which is a hook-shaped gripping head used to hook the handles or lifting rings of frozen materials.

[0033] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple; relevant parts can be referred to the method section.

[0034] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
