Description

Technical Field

[0001] The present application relates to the field of photographic equipment, and in particular to a tripod with a pedal-type upright locking mechanism. Background Art

[0002] In the current photography industry, a tripod is a very common photographic equipment. It is easier to carry and move back and forth than a tripod. In order to meet the needs of rotating shooting, switching between close-up and long-distance shooting, and dynamic follow-up shooting, most tripods on the market have the function of free swinging in multiple directions with the support point as the axis. However, when shooting statically for a long time, the tripod needs to be able to stand upright, so an upright locking mechanism is needed to complete the switch between free swinging and upright locking. Most upright locking mechanisms on the market now use spiral locking, which is time-consuming and cumbersome, and cannot be done in one step. Frequent switching between free swinging and upright locking states will be particularly cumbersome, which greatly reduces work efficiency. In addition, the operator needs to adjust by hand, which restricts the photographer's hands and interrupts the continuity of photography.
