Abstract

The utility model provides a hand-operated swing arm. The hand-operated swing arm comprises a tripod and a main shaft. The main shaft is connected with the tripod through a fastening handle. Rapid installation between the main shaft and the tripod is realized through a 3/8 screw. The top part of the main shaft is provided with a swing arm unit. An adjusting handle is arranged at the connecting part between the swing arm unit and the main shaft. One side of the swing arm unit is provided with a counterweight telescoping tube. The counterweight telescoping tube is further fixedly provided with a counterweight disk. One end of the swing arm unit is further provided with a holder. The top part of the swing arm unit and the main shaft are connected through the telescoping tube. The middle part of the telescoping tube is broken and is provided with a length-regulating handle. Most parts of the product are made of aluminum alloy and polyethylene, so that the product is convenient to transport and carry. Simple structure of the hand-operated swing arm enables the operation to be more convenient, and the hand-operated swing arm is applicable to shooting in a narrow and special space. A bowl opening of 65mm-65mm is matched with the hand-operated swing arm for usage, so that the applicability of the product is improved.

Description

A kind of hand-operated rocker arm

Technical field

The utility model belongs to photographic auxiliary equipment field, especially relates to a kind of hand-operated rocker arm.

Background technology

In existing technology, general hand-operated rocker arm all adopts square eight-corner tube composition, and arm body reaches several meters.Existing technology comes with some shortcomings.1, general hand-operated rocker arm arm tube section is larger, and arm body is longer, and the increase of weight and volume makes it be not suitable for taking at narrow space, has also improved transport difficulty and cost.2, complicated contour structures has also strengthened production and assembly and the user difficulty while loading and unloading, has reduced efficiency.

Utility model content

The purpose of this utility model be to provide a kind of simple to operate, be convenient to transportation and a kind of hand-operated rocker arm of carrying, be especially applicable to being useful in narrow and small special space and take use.

The technical solution of the utility model is: the utility model is a kind of hand-operated rocker arm, comprise tripod, also comprise main shaft, described main shaft and tripod link together by fastening handle, described fastening handle also comprises 3/8 screw, described main shaft is by the Fast Installation of a 3/8 screw realization and tripod, described spindle top is provided with rocking arm, described rocking arm and main shaft are movably connected, the junction of described rocking arm and main shaft is provided with adjusting handle, described rocking arm one side is provided with counterweight draw-tube, described counterweight draw-tube and rocking arm are locked mother by counterweight tube and are movably connected, on described counterweight draw-tube, be also fixed with balancing disk, described rocking arm one end is also provided with The Cloud Terrace, described The Cloud Terrace bottom and rocking arm are flexibly connected, described rocking arm top and main shaft link together by draw-tube, in the middle of described draw-tube, it is disrupted configuration, in the middle of described draw-tube, be provided with and regulate length handle, the hand of spiral at the inner two ends of described adjusting length handle is contrary, described The Cloud Terrace is spherical bowl structure, described the rim of a bowl diameter is 65mm-75mm.

Advantage and the good effect that the utlity model has are: the structure major part of product all adopts aluminium alloy and polythene material to design, and carrying length is 1.1 meters, and carrying weight is 4kg, make product be convenient to transportation and carry.Simple structural design can make operation more easy, is useful in narrow and small special space and takes.Coordinate the rim of a bowl of 65mm-65mm to use, increased the applicability of product.
