Description

TECHNICAL FIELD

[0001] The embodiment of the utility model relates to photographic equipment and mobile phone accessory technical field, concretely relates to an automatic telescopic part and support tripod. BACKGROUND

[0002] This part introduces the background technology related to each aspect of the embodiment of the utility model to the reader, and it is believed that it can provide useful background information for the reader, so as to help the reader better understand each aspect of the embodiment of the utility model. Therefore, it can be understood that the description in this part is for the above purpose, and not for the acknowledgement of the prior art.

[0003] The tripod is a support frame used to stabilize and support equipment. At present, the tripod is often used in the technical fields of photography, surveying and mapping, medical instruments, industrial instruments, home furnishing, etc. The tripod is generally used to place cameras, lamps, reflectors, measuring and surveying instruments and other equipment that need to be stabilized to avoid human factors affecting the photography or measurement effect. The existing tripod includes three legs, but in order to ensure stability while increasing the height adjustment, the telescopic rods on the three legs can be freely retracted, and the height of the tripod needs to be adjusted to adapt to different shooting requirements, and the vertical telescopic support rod at the top is also used to adjust the height together.

[0004] For different use environments, users adjust the height and stability of the tripod as needed. When erecting, in order to ensure the flatness of the upper end surface, the lengths of the telescopic rods on the three support legs need to be manually adjusted. The manually adjusted tripod is far less accurate than the automatically adjusted one in terms of adjustment accuracy, which is time-consuming and laborious and seriously affects the accuracy of the data and results of the work. Most of the automatic telescopic rods used in the market are two-section telescopic rods, and the minimum length is relatively large when fully retracted, which is not conducive to some simple and space-limited designs. There are multi-section automatic telescopic devices, but they have complex structures, are cumbersome to process, and have large use spaces. Therefore, it is necessary to obtain an automatic telescopic rod and an automatic support with a simple structure and saving space. CONTENT OF THE UTILITY MODEL
