L shape collet, the lateral arms 20 of two collets 2 are inserted in the two sides of shell 1, and the lateral arms 20 and the shell respectively
Body 1 is slidably connected, and the bracket 3 includes longitudinal support arm 30 and the tray 31 positioned at longitudinal 30 lower end of support arm, described vertical
It is inserted in the shell 1 to the upper end of support arm 3, which is characterized in that be equipped in the shell 1 for driving two 2 phases of collet
Mutually separate or close to each other driving mechanism 4, the shell 1 is interior to be equipped with wiring board 5, is fixed with fixed frame in the shell 1
8, the fixed frame 8 is equipped with adjustable shelf 9, and the adjustable shelf 9 can the relatively described fixed frame 8 slide up and down, longitudinal branch
Arm 3 is set on the adjustable shelf 9, and the edge of the fixed frame 8 is equipped with soft-touch control 82, and the soft-touch control 82 is arranged in institute
The side of shell 1 is stated, the soft-touch control 82 is electrically connected at the wiring board 5, and the soft-touch control 82 is used for the line
The instruction of 5 input control of road plate, the wiring board 5 controls the operating of driving mechanism 4 according to the control instruction, to drive two collets
2 clamp mobile phone 100.
In above-mentioned touch sensible mechanism, it is provided with driving mechanism 4 in shell 1, is provided with to touch in the side of shell 1 and open
82 are closed, when mobile phone is placed between two collets 2 by user, soft-touch control 82 can be touched with finger, the soft-touch control 82 is defeated
Electric signal out is transmitted to wiring board 5 as control instruction, rear board 5 according to the control instruction control driving mechanism 4
Operating, and then two collets 2 is driven to clamp mobile phone 100.Compared to existing technologies, the present invention is realized with touch manner key
Enter control instruction, and realize the automation driving of collet 2, substantially increases the handling and automation of handset bracket
Performance has better meet user and the market demand.
In the present embodiment, the edge of the fixed frame 8 is set there are two soft-touch control 82, and two soft-touch controls 82 are worn respectively
Set on the two sides of the shell 1.
In the present embodiment, the driving mechanism 4 includes gear-box 41 and motor 42, and the gear-box 41 includes output
Gear 40, the output gear 40 pass through the gear-box 41, and the end of the lateral arms 20 is formed with spur rack 22, and two

40 are meshed, and when the motor 42 operating, drive output gear 40 to rotate by the gear-box 41, to drive two collets
2 are located remotely from each other or close to each other.
The first gear 43 successively engaged, second gear 44, the are equipped in the gear-box 41 as a preferred method,
Three gears 45 and the 4th gear 46, the first gear 43 are sheathed in the shaft of motor 42, the end face of the 4th gear 46
It is oppositely arranged with the end face of output gear 40, and the 4th gear 46 is engaged with output gear 40 by contrate gear 47.Into
One step, third spring 48 is folded between the 4th gear 46 and the shell 1.The effect of the third spring 48 is to drive
Make the 4th gear 46 keep pushing against with output gear 40, and then realizes transmission effect.
In above structure, due to being folded with third spring 48, and the 4th gear between the 4th gear 46 and the shell 1
46 are engaged with output gear 40 by contrate gear 47, so after two collets 2 clamp mobile phone 100, if motor 42 continues
Operating, then the 4th gear 46 will overcome the elastic force of third spring 48 with output gear 40 and occur to slide relatively, to eliminate
Biggish driving force effectively prevents damaging mobile phone 100 because the chucking power of two collets 2 is excessive.
The above is preferred embodiments of the present invention, is not intended to restrict the invention, all in technology model of the invention
Interior done modification, equivalent replacement or improvement etc. are enclosed, should be included in the range of of the invention protect.
