When the shifting block 50 is shifted to the engaging position P1 or the releasing position P2, the engaging blocks 521 of the elastic legs 52 are engaged with the engaging grooves 16 respectively for temporary positioning. In other words, when the dial 50 is displaced to the engaging position P1, the latch 521 of each elastic leg 52 is engaged with the engaging groove 16 relatively forward and relatively close to the operating chamber 11, and when the dial 50 is displaced to the releasing position P2, the latch 521 of each elastic leg 52 is engaged with the engaging groove 16 relatively rearward and relatively far from the operating chamber 11.

The main body 10 has a cover 17 and a mounting portion 18, the cover 17 covers the main body 10 to position the driving member 20, the return member 30, the expansion bracket 40 and the shifting block 50 in the main body 10. The mounting portion 18 is located at the opposite side of the cover 17, and the mounting portion 18 is mainly used for the main body 10 to be combined with an external component, such as a fixing seat a (as shown in fig. 7) for fixing or a joint B (as shown in fig. 8), which is a joint for a sports camera in the preferred embodiment, but the invention is not limited thereto, and can also be used for other purposes.

In actual operation, the main body 10 can be combined with the fixing seat a through the mounting portion 18 to be fixed on the rear-view mirror of the motorcycle 60 (as shown in fig. 9), when the operator wants to fix the mobile communication device 70 on the bracket, the telescopic frame 40 located on one side can be extended outwards with one hand, at this time, the extended telescopic frame 40 is displaced, the driving section 43 provided on the sliding portion 41 thereof drives the transmission portion 21 to drive the driving member 20 to rotate, the sliding portion 41 of the other telescopic frame 40 is also driven to extend outwards by the rotation of the transmission portion 21 due to the rotation of the driving section 43, so that the two telescopic frames 40 extend synchronously to make the two abutting portions 42 away from each other (as shown in fig. 4), the operator can easily place the mobile communication device 70 with one hand, and then release the telescopic frame 40, the driving member 20 can be reversed by the prestress of the returning member 30, at this time, the driving portion 21 can also rotate reversely to drive the two sliding portions 41 to retract the main body 10 synchronously through the driving section 43, until the two abutting portions 42 are relatively close to each other to temporarily clamp and position the driving signal device 70 (as shown in fig. 5). To avoid the situation that the two abutting portions 42 are opened by pulling the telescopic frame 40 by mistake to cause the mobile communication device to fall, the dial block 50 can be shifted to the locking position P1 to abut the ring gear 223 with the stop gear 51 (as shown in fig. 6), so that the rotary disc 22 can not rotate to avoid the two abutting portions 42 being opened to release the mobile communication device to fall, and the rotary disc 22 can only rotate by allowing the stop gear 51 to be separated from the ring gear 223 when the dial block 50 is shifted to the release position P2.

It can be easily understood from the above description that the present invention is characterized in that when an object is clamped and positioned by the adjustable telescopic bracket 100 of the present invention, an operator can synchronously pull the telescopic bracket 40 to extend by using one hand, so that the operator can easily place the object at a predetermined position of the adjustable telescopic bracket 100 by using one hand, and then the driving member 20 is reversed by releasing the telescopic bracket 40 and the restoring member 30, so that the sliding portion 41 can be synchronously retracted into the body 10, the object can be temporarily clamped and positioned by the relative approach of the abutting portion 42, compared with the conventional bracket which needs to pull the two telescopic clamps by one hand, the adjustable telescopic bracket 100 can be operated more conveniently and quickly to clamp and position the object to be fixed, thereby achieving the convenience of object clamping and positioning, and the object to be fixed has no risk of falling down during the clamping and positioning process, relatively has the safety in use.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
