The first lead screw 42 and the second lead screw 43 have opposite screw directions, so that the first and second clamp arms 21 and 31 are controlled to synchronously move toward and away from each other. In theory, only one side of the lead screw may be provided, so that only the clamping arm on the side where the lead screw is located can move, and the clamping arm on the other side is fixed, and the effect of clamping/releasing the mobile terminal can be achieved.

The transmission assembly 40 is mounted on the transmission assembly mounting portion 121 disposed in the rear housing 12, and specifically, the first guide wheel 44 and the second guide wheel 45 are correspondingly inserted into the slots of the first guide wheel mounting seat 1211 and the second guide wheel mounting seat 1212 disposed on the rear housing 12, so that the ratchet 41 is located in the gap between the first guide wheel mounting seat 1211 and the second guide wheel mounting seat 1212, thereby mounting the transmission assembly 40 on the rear housing 12.

The control assembly 50 includes an operating lever 51, an operating lever returning member 52, a rotation shaft positioning member 53, and an operating lever positioning member 54. The operating rod 51 comprises a rotating shaft 511, a pressing end 512 and a locking end 513, wherein the axis of the rotating shaft 51 is parallel to the clamping direction, and the pressing end 512 and the locking end 513 are respectively located on two sides of the axis of the rotating shaft 511. The rotation shaft positioning member 53 is used to mount the rotation shaft 511 of the operation lever 51 on the rear case 12, and the operation lever positioning member 54 is used to dispose the locking end 513 of the operation lever 51 and the operation lever returning member 52 on the rear case 12. The lever return 52 is preferably a compression spring, and in other embodiments, the lever return 52 may be other resilient members, such as resilient pads, etc.

In the illustrated embodiment, the lever return 52 is disposed between the locking end 513 and the rear housing 12; in other embodiments, the lever restoring member 52 can be disposed between the front housing 11 and the pressing end 512, as long as the force applied by the lever restoring member 52 to the operating lever 51 is enough to move the pawl at the end of the locking end 513 toward the ratchet teeth of the ratchet wheel 41, so that the pawl can be locked with the ratchet teeth of the ratchet wheel 41 to rotate the locking ratchet wheel 41.

The control unit 50 is mounted on a control unit mounting portion 122 disposed in the rear case 12, specifically, the rotating shaft 511 is mounted on a rotating shaft mounting seat 1221 of the rear case 12 through a rotating shaft positioning member 53, the pressing end 512 corresponds to an unlocking button mounting hole 1222 formed in the rear case 12, one end of the operating lever reset member 52 is sleeved on a reset member positioning post 514 on one side of the locking end 513, the other end of the operating lever reset member is disposed in the operating lever reset member mounting seat 1223, and the operating lever reset member mounting seat 1223 is disposed in the operating lever reset member mounting seat 1223. Thus, the pressing end 512 and the locking end 513 form a lever (see-saw) with the rotation shaft 511 as a fulcrum, and the lever restoring member 52 provides a force for lifting the locking end 513 forward, so that the pawl at the end of the locking end 513 can be engaged with the ratchet 41, thereby locking the transmission assembly 40. The unlocking button mounting hole 1222 is used for mounting an unlocking button, the unlocking button is fixedly connected with the pressing end 512 of the operating rod 51, when the pressing end 512 is pressed, the operating rod 51 rotates around the rotating shaft 511, so that the locking end 513 is disengaged from the ratchet teeth on the ratchet wheel 41, and unlocking is realized.

In use, the pressing end 512 of the operating lever 51 is pressed by the unlocking button at the unlocking button mounting hole 1222 of the rear case 12, the operating lever 51 rotates so that the pawl of the locking end 513 is disengaged from the ratchet 41, and the operating lever reset 52 is pressed. After the ratchet 41 is unlocked, the first clamping arm resetting piece 22 and the second clamping arm resetting piece 32 which are originally compressed generate acting force to drive the first clamping arm 21 and the second clamping arm 31 to move outwards respectively, and in the process, the first clamping arm 21 and the second clamping arm 31 drive the transmission assembly 40 to rotate through the first lead screw 42 and the second lead screw 43.

When the first and second clamping arms 21 and 31 move to the maximum open position, or the locking end 513 is engaged with the ratchet wheel 41 again, the first and second screws 42 and 43 and the ratchet wheel 41 stop rotating, and at this time, the user can place the mobile terminal between the first and second clamping arms 21 and 31. Then, the first and second clamping arms 21 and 31 are pushed to approach each other along the clamping direction until the first and second clamping arms 21 and 31 abut against the side walls of the mobile terminal, respectively. In the process, the first and second clamp arms 21 and 31 drive the first and second screws 42 and 43 and the ratchet 41 to rotate in opposite directions, and the ratchet 41 lifts the locking end 513 when rotating in opposite directions, so that the locking end is not locked, i.e. the ratchet 41 can rotate freely in opposite directions.
