Fig. 9 is a perspective view of a locking state of a holder embodiment of the mobile terminal of the present invention. Fig. 10 is a cross-sectional view at C-C in fig. 9.

Referring to fig. 1 to 10, in the embodiment, when the handle 420 is in the locked state, the handle 420 is located at the locking mark 252 of the limiting groove 250, and the handle 420 drives the screw 410 to rotate to the preset position, so that one end of the screw 410 facing the sliding rod 300 abuts against the sliding rod 300 to limit the second bracket 200 and the sliding rod 300.

Referring to fig. 1 to 10, the present invention provides a holder for a mobile terminal b, when a holder a is in a standby state, a first cradle 100 is close to a second cradle 200; the handle 420 is located at the unlocking index 251 of the limiting groove 250, so that the screw 410 is not abutted against the sliding rod 300, and the second bracket 200 can move axially along the sliding rod 300.

When the gripper a is ready to grip the mobile terminal b, the user applies a pulling force to the first cradle 100 or the second cradle 200, and the second cradle 200 is axially moved along the sliding bar 300 such that the first cradle 100 and the second cradle 200 are separated; when the first bracket 100 is separated from the second bracket 200, the spring 330 is stressed and stores elastic potential energy, so that the rotating part 320 of the sliding rod 300 slides in the second through hole 211, and the main body part 310 of the sliding rod 300 slides on the inner peripheral wall of the step 212 along the axial direction of the sliding rod 300. When the first cradle 100 and the second cradle 200 are separated from each other by a predetermined distance, the user stops applying the pulling force, the mobile terminal b is clamped in the first clamping portion 120 of the first cradle 100 and the second clamping portion 220 of the second cradle 200, the spring 330 releases the elastic potential energy to apply a force to the first cradle 100 and the second cradle 200, and the first cradle 100 and the second cradle 200 move toward each other, so that the first clamping portion 120 and the second clamping portion 220 stably clamp the mobile terminal b.

When the holder a holds the mobile terminal b, the handle 420 is rotated to the locking mark 252 of the limiting groove 250 to lock the second bracket 200; in the rotating process of the handle 420, the handle 420 drives the screw 410 to rotate through the rack 411, so that one end of the screw 410 facing the sliding rod 300 abuts against the sliding rod 300 to limit the relative movement between the sliding rod 300 and the second bracket 200, and the mobile terminal b is stably clamped on the clamp holder a.

When the holder a does not need to hold the mobile terminal b, the handle 420 rotates from the locking mark 252 to the unlocking mark 251 of the limiting groove 250, the handle 420 drives the screw 410 to rotate, so that one end of the screw 410, facing the sliding rod 300, is not in contact with the sliding rod 300, and a user pulls the first bracket 100 and the second bracket 200 to enable the first bracket 100 and the second bracket 200 to move away from each other, so that the mobile terminal b is taken out of the holder a; after the removal, the user does not apply a force to the holder a, so that the first bracket 100 and the second bracket 200 move toward each other by the spring 330, and the holder a is restored to the ready-to-use state.

In the present invention, the second cradle 200 slides relative to the first cradle 100 along the axial direction of the sliding rod 300, so that the second cradle 200 is separated from the first cradle 100 to clamp both ends of the mobile terminal b with the first cradle 100 and the second cradle 200 being able to face each other; after the mobile terminal b is clamped between the first bracket 100 and the second bracket 200, the limiting assembly is switched from the unlocking position to the locking position, so that the limiting assembly abuts against and limits the sliding rod 300 to limit the relative movement of the second bracket 200 and the first bracket 100, and the mobile terminal b is stably clamped in the clamp holder a.
