[0035] Further preferably, a gear groove 22 for placing the synchronous gear is arranged on one of the extension parts, or the recesses on the two extension parts are communicated to form a gear groove, so as to maintain the stability of the connection between the synchronous gear and the extension part (synchronous rack) and prevent the synchronous gear from being displaced or loosened.

[0036] Further preferably, each of the extension parts is provided with a connecting block 23, and the connecting block is connected with the holder body through a return spring, so that the clamping arm can be reset through the return spring when it is not locked, and the clamping arm can be kept in the clamped state.

[0037] Further preferably, the bottom of the bracket body or the sidewall of the rear fixed cover plate is provided with a connecting and fixing part (for example, an air outlet clamp, a sticking piece, etc.) for fixing on a car (an air outlet), a desktop, a wall surface, or the like.

[0038] A through slot 103 is horizontally arranged on the bracket body above the clamping arm, and the composite pressing arm is movably arranged in the slot.

[0039] The composite pressing arm has the following two main functions: first, when the user connects the mobile phone with the direct body, the mobile phone is pressed to generate a downward pressure to drive the product to displace, in order to balance the force on the product and prevent displacement, the user can lift the fulcrum of the outer extension of the composite pressing arm while pressing the mobile phone, so as to apply an upward force to the bracket body, thereby preventing the bracket body from being skewed or even falling off due to uneven force when the mobile phone is installed; second, when the clamping arm and the composite pressing arm are tightened to the center along the left-right direction, the inclined surface of the clamping arm applies a pressure F1 to the mobile phone, and the inclined surface of the composite pressing arm applies a pressure F2 to the mobile phone, so that the mobile phone receives a resultant force F of F1 and F2 and is displaced along the direction of the resultant force F and tightly adheres to the front fixed cover.

[0040] Further preferably, the lower part of the composite pressing arm is movably connected with a clamping groove on one of the clamping arms through a clamping hook 61, so that the composite pressing arm can move outward synchronously with the opening of the clamping arm to cooperate with the clamping arm to realize the clamping operation of different mobile phones.

[0041] The bottom of the bracket body is connected with the platform connecting seat, and the connector platform is movably connected with the platform connecting seat, so that the connector platform can move forward and backward on the platform connecting seat, and the connector fixed on the connector platform moves synchronously with the connector platform to adjust the position of the device connector, so that the mobile phone can be more quickly and accurately connected with the device connector.

[0042] Further preferably, the front fixed cover and the platform connecting seat are of an integrated structure.

[0043] Further preferably, the protruding part 91 on the side surface of the connector platform is connected with the groove body 92 on the platform connecting seat through a spring to realize the functions of buffering adjustment and resetting.

[0044] The rocker is rotatably arranged on the bracket body or the platform connecting seat, the pressing rod is liftably arranged in the lifting slot 51 on the bracket body (the rear fixed cover), and the lower end of the pressing rod is in contact with and presses against the rear part of the rocker to drive the rocker to rotate, so that the front part of the rocker is lifted upward to lift the mobile phone to be separated from the device connector.

[0045] When the user installs the mobile phone on the support body and connects the mobile phone interface with the equipment connector, the front part of the flap is pressed down under the gravity of the mobile phone, at this time, the rear part of the flap is raised up under the action of the principle of lever, and drives the pressure rod to move up; when the user takes out the mobile phone from the support body, the upward pulling force generated by pulling out the mobile phone drives the mobile phone to displace, at the same time, the finger can press down the pressure rod synchronously to apply downward pressure to the rear part of the flap, so that the front part of the flap is lifted to apply an upward thrust to the mobile phone, so that the mobile phone can be pulled out more easily, and the support body can be more balanced in stress, and is not easy to displace or fall.

[0046] Further preferably, the flap is arranged on both sides above the connector platform.

[0047] Further preferably, a limiting block for limiting the lifting limit position of the pressure rod is arranged on the support body or in the lifting chute.

[0048] The locking mechanism can lock the clamping arm and the connector platform respectively, or simultaneously lock the clamping arm and the connector platform to fix the positions of the clamping arm and the equipment connector. The following takes the simultaneous locking of the clamping arm and the connector platform as an example for illustration.

[0049] The locking mechanism comprises a brake shaft 111, platform brake pieces (a platform brake piece L112 and a platform brake piece R113), a shaft brake piece (a shaft brake piece L114 and a shaft brake piece R115), a locking bolt 116, a locking nut 117 and a locking knob 118.

[0050] The upper end of the brake shaft is connected with the synchronous gear, the lower end of the brake shaft passes through the extension and extends into the platform connecting seat, the platform brake pieces are arranged on both sides of the connector platform, the end of the locking bolt passes through the platform connecting seat and the two platform brake pieces and is threadedly connected with the locking nut in the locking knob, the shaft brake pieces are movably arranged on the locking bolt inside the platform brake pieces, the two shaft brake pieces are arranged on both sides of the brake shaft, the locking nut is connected with the locking knob, and the connection position of the locking bolt and the locking nut is adjusted by rotating the locking knob to press the inner end of the locking knob against the platform brake pieces and the shaft brake pieces, so that the shaft brake pieces clamp the brake shaft and the platform brake pieces clamp the shaft brake pieces, thereby realizing the synchronous locking of the positions of the connector platform and the clamping arm.

[0051] In the embodiment, the rotation shaft is controlled by the rotation shaft brake piece L and the rotation shaft brake piece R to move to fix or release the position of the support arm, and the connector platform is controlled by the platform brake piece L and the platform brake piece R to move to fix or release the position of the connector. The rotation shaft brake piece L and the rotation shaft brake piece R and the platform brake piece L and the platform brake piece R are all penetrated on the bolt, and are extruded by the rotation of the nut on the bolt to realize the positioning of the clamping arm, the composite pressing arm and the connector.

[0052] When the positions of the clamping arm and the connector platform need to be locked, the position of the connector platform is first adjusted according to the position of the mobile phone interface, so that the device connector can be aligned with the mobile phone interface when the mobile phone is moved downward; the clamping arm and the composite pressing arm are synchronously displaced to the target position, at this time, with the movement of the clamping arm, the synchronous gear also synchronously rotates the brake rotation shaft; the locking knob is rotated, so that the rotation shaft brake piece approaches and clamps the brake rotation shaft, preventing the brake rotation shaft and the synchronous gear from continuing to rotate, thereby locking the position of the clamping arm, and at the same time, the platform brake piece tightly or clamps the rotation shaft brake piece, so that the connector platform cannot move forward and backward, thereby locking the position of the connector platform.

[0053] When the clamping arm and the connector platform need to be unlocked, only the locking knob needs to be reversely rotated, so that the rotation shaft brake piece is separated from the brake rotation shaft and the platform brake piece, the clamping arm is clamped inward under the action of the return spring, and the connector platform moves forward and backward under the action of the spring to reset.

[0054] Further preferably, the platform brake piece is movably arranged in the positioning groove 119 on both sides of the connector platform.

[0055] Further preferably, the platform brake piece is provided with a translation limiting groove 1110 allowing the locking bolt to pass through, which not only prevents the locking bolt from interfering with the forward and backward movement of the connector platform, but also can limit the forward and backward translation position by using the translation limiting groove and the locking bolt.

[0056] Further preferably, the platform connecting seat is provided with a through hole 1111 allowing the locking bolt to pass through.

[0057] When adjusting the position of the clamping arm and the device connector, the locking knob is turned to loosen the locking nut and bolt, so that the clamping arm and the connector platform are in a free state; the clamping arm (composite compression arm synchronous movement) is opened, and the connector platform is pulled to install the mobile phone on the support body, so that the interface of the mobile phone is connected with the device connector, the clamping arm is loosened to clamp the two sides of the mobile phone, then the locking knob is reversely turned, so that the locking nut (or the inner side of the locking knob) extrudes the locking piece and the rotating shaft locking piece of the platform to lock the position of the clamping arm and the connector platform, so that the position of the clamping arm and the connector platform is pre-adjusted according to the size and interface position of the mobile phone, and the next time the same size mobile phone is installed, no adjustment is needed, the accuracy and efficiency of plugging are improved.

[0058] When installing the mobile phone, as shown in Figure 5, the user holds the mobile phone and inserts it into the support body with the pre-adjusted position, then the thumb can press the composite compression arm upward, and the other fingers press the top of the mobile phone downward, so that the mobile phone can move downward along the clamping arm and the clamping arm pulley and be accurately plugged with the device connector, thereby completing single-handed installation.

[0059] When taking out the mobile phone, as shown in Figure 6, the user holds the mobile phone and lifts it upward, and the fingers holding the back of the mobile phone press the pressing rod downward to drive the front end of the rocker to lift, so that the rocker pushes the mobile phone upward to separate from the device connector, facilitating the upward movement of the mobile phone along the clamping arm and the clamping arm pulley, thereby completing single-handed pulling out.

[0060] The adjustable mobile phone support has the following beneficial effects:

[0061] 1. The front and rear positions of the device connector can be adjusted according to the position of the mobile phone interface through the front and rear movement of the connector platform, so that the device connector and the mobile phone interface are accurately aligned, the accuracy and stability of mobile phone connection are effectively improved, and the service life of the device is prolonged.
