Description

Technical Field

[0001] The utility model relates to a fixing structure of a leg tube connector and a leg tube, in particular to a pressing fixing structure of a leg tube connector and a leg tube with a movable hole for adjusting the angle of the leg tube. Background Art

[0002] The existing fixing structure of the leg tube connector and the leg tube, such as a common camera tripod, has three leg tubes that can adjust the angle respectively. Its structure includes a positioning step, a leg tube, a leg tube fastener, a seesaw positioning part and a seesaw fastener on the tripod leg tube connector. The leg tube connector is combined with the leg tube by using the leg tube fastener. When the leg tube is adjusted and rotated to a desired angle, one end of the seesaw positioning part can be loosened to make the other end of the seesaw positioning part abut against the positioning step, so that the leg tube and the leg tube connector are fixed to each other. One end of the seesaw positioning part can be pressed to make the other end of the seesaw positioning part detach from the positioning step, so that the leg tube and the leg tube connector can rotate relative to each other with the leg tube fastener as the axis. This existing structure requires the use of an independent seesaw fastener as the rotation axis of the seesaw positioning part, that is, different axes are used for the rotation of the leg tube and the seesaw.

[0003] However, in the existing tripods with three legs that can adjust the angles separately, the seesaw positioning parts directly contact and resist the positioning steps. The seesaw positioning parts bear the force of the entire structure to support the entire tripod. Therefore, there are specific requirements for the material and strength of the seesaw positioning parts to avoid wear, breakage or deformation. Therefore, more resources need to be consumed and more expensive materials need to be used to achieve structural stability. Utility Model Content

By pressing the pressing portion, the second guide post slides upward along the internal guide groove, and the first guide post slides to the right along the internal guide groove to move the leg tube, so that the fastener is located in the adjustment position. The positioning pin and the positioning groove are separated from each other, and the leg tube is rotated to the expanded state with the fastener as the axis.
