Description

Multifunctional round jaw device

The present invention relates to a round jaw device, and more particularly to a multifunctional round jaw device that can be disassembled and assembled to facilitate carrying and receiving.

The shovel is an iron excavation tool, which can be roughly divided into large, small, fixed, or folded. Among them, the shank and the body of the large shovel structure are mostly fixed, and most of them are inconvenient to carry due to their large size. It is used in civil engineering and agro-horticulture, and the small shovel can be folded for specific convenience, and is suitable for outdoor activities such as camping and mountaineering.

In recent years, natural disasters have been frequent, and disasters such as earthquakes, landslides and typhoons can be said to be commonplace, so many disaster relief activities have become an indispensable part. Many disasters require rescuers or firefighters to use human resources to dig for rescue. At this time, multi-functional hand tools are the best and most effective disaster relief option.

However, the traditional large shovel is not only bulky and large, but also has a single excavation function. In addition, the small shovel is based on the limitation of volume, the length of the shank is short, and the holding force is inconvenient, so it cannot meet the post-disaster rescue. The need for high efficiency and practicality needs to be improved.

Referring to Fig. 1, a new type of shovel of the Republic of China No. M333764, "a shovel with a grip", the shovel includes a grip 13 for gripping, a shovel seat 14 at the bottom of the grip 13, and a A grip 15 located on the grip 13. The grip 13 includes a rod wall 131, and the rod wall 131 has a surface 132 and at least one groove 133 disposed on the surface 132 and in a non-parallel relationship with a biasing direction 16, and the groove 133 is a continuous spiral.

By providing the groove 133 on the rod wall 131 of the grip 13 held by an operator, and letting the groove 133 not parallel to the design of the biasing direction 16, the operator can be held by the shovel Moreover, when the force is applied along the biasing direction 16, a better blocking force is generated, thereby improving the anti-slip effect of the shovel.

From the above description, it is known that the conventional shovel with the grip has the following disadvantages in actual use:

First, no effort

Although the spiral groove 133 described above can generate a blocking force to prevent the palm held by the grip 13 from sliding downward, the grip 13 of the shovel cannot adjust the length, and the body shape is different. The operator does not provide a more labor-saving grip distance to save the operator's physical exertion.

Second, lack of convenience

Rescue work after the disaster is a matter of seconds, so it is not only necessary to carry out the daylight in the daylight, but also to carry out disaster relief in a dim environment. When the shovel is used in a dim environment, the operator will need to use additional lighting equipment. , will cause the operator's inconvenience.

Third, lack of functionality

As modern people pay attention to practical and diversified life, sometimes it is no longer just a single functional requirement for a single product, but a multiple use of a single product, which can only improve the slippery effect of the shovel.
