The damper shaft mechanism 30 has an axis, i.e., a rotational axis direction of the device connecting rod 20 with respect to the support rod 10. The damping shaft mechanism comprises a screw 31, a damping spring 32, a limiter 33, a nut 34 and a shaft end cover 35 which are arranged along the axis. The damping spring 32 is sleeved on the screw 31, and the head of one end of the screw 31 can restrain one end of the damping spring 32 in the axial direction. The screw 31 passes through the first rotating shaft part 121 and the second rotating shaft part 22, and the rear end thereof is screwed with a nut 34, and the nut 34 is a hexagonal nut and is placed in the stopper 33. The stopper 33 is provided with a first engaging groove 331 parallel to the rotation axis direction, and is engaged into a corresponding engaging rib 1211 of the first rotation axis 121 along the axis direction to be fixed on the first rotation axis 121, so that the damping spring 30 provides a pressing force along the axis direction to the first rotation axis 121 and the second rotation axis 22.

The stretching rod 12 defines a stretching direction, which intersects with the rotation axis direction as indicated by arrows in fig. 7 and 8. In the illustrated example, the telescoping direction is perpendicular to the rotation axis direction.

The support rod 10 further includes a compression spring 13, and the compression spring 13 is provided between the stretching rod 12 and the fixed rod 11 in the stretching direction, and provides an elastic force to the stretching rod 12 to protrude outward in the stretching direction relative to the fixed rod 11. The telescopic locking mechanism 40 is installed in the fixed rod 11, and provides the stretching rod 12 with resistance against the elastic force of the compression spring 13 to restrain the position of the stretching rod 12 relative to the fixed rod 11. In the illustrated example, the compression springs 13 are symmetrically provided on both sides of the telescopic locking mechanism 40, and the compression springs 13 on both sides uniformly provide the elastic force.

The first fixing member 111 is provided with a key hole 1112, in which a portion of the retractable locking mechanism 40 to be pressed is inserted. The first fixing member 111 is provided therein with a key shaft mounting groove 1113 for mounting a tilting shaft of a pressing portion of the telescopic locking mechanism 40.

The key sheet 41 has a pressing portion 411 and a key shaft portion 412. The pressing portion 411 defines a pressing direction perpendicular to the extending and contracting direction, the pressing portion 411 is fitted into the key hole 1112, and the key shaft portion 412 is provided at one side of the pressing portion 411 and rotatably positioned in the key shaft mounting groove 1113. The pressing portion 411 is provided with a second one-way tooth 413 on the side opposite to the pressing direction, and the second one-way tooth 413 is engageable with the first one-way tooth 1223 to provide the first one-way tooth 1223 with resistance against the elastic force of the compression spring 13. The first unidirectional tooth 1223 and the second unidirectional tooth 413 have triangular tooth shapes, and can slide relative to each other in the forward direction (the direction in which the stretching rod 12 retracts relative to the fixing rod 11) and lock in the reverse direction (the direction in which the stretching rod 12 extends relative to the fixing rod 11).

When the pressing portion 411 is pressed in the pressing direction, the entire key sheet 41 rotates about the key shaft portion 412, thereby pressing the return spring 42, and the second one-way teeth 413 gradually disengage from the engaged first one-way teeth 1223, at which time the elastic force of the compression spring 13 pushes the stretching rod 12 to extend outward in the stretching direction. After the stretching rod 12 has a suitable extension relative to the fixing rod 11, the pressing portion 411 is released, the entire key sheet 41 is rotated around the key shaft portion 412 by the urging force of the return spring 42, and the second one-way tooth 413 is lifted up along with the pressing portion 411 to bite the first one-way tooth 1223, thereby holding the stretching rod 12 at the current position.

When the stretching rod 12 needs to be retracted relative to the fixing rod 11, a force is applied to the stretching rod 12 in the fixing rod 11 along the stretching direction, the force is a positive force of the first one-way tooth 1223 and the second one-way tooth 413, and the first one-way tooth 1223 slides relative to the second one-way tooth 413. After the stretching rod 12 is retracted to the proper position, the force application is stopped, and the first one-way tooth 1223 is engaged with the second one-way tooth 413, so that the stretching rod 12 is locked.

The attachment 50 and the equipment connector 60 are respectively provided at both ends of the support rod 10 and the equipment connecting rod 20, and when the equipment connecting rod 20 is located on a plane passing through the rotation axis and the support rod 10, the attachment 50 and the equipment connector 60 are located on the same side of the plane.

The attachment 50 includes a mounting disk 51, an attachment holder 52, and a soft rubber sheet 53, the attachment holder 52 fixing the mounting disk 51 into the attachment mounting hole 1123 by a fastener, the soft rubber sheet 53 being thereby provided on the outer side of the attachment holder 52. One end of the support rod 10 can be attached to a mounting surface, such as the back surface of a vehicle-mounted display, by the soft film 53.

The device connector 60 is used to connect an electronic device, and in the illustrated embodiment, the device connector 60 is a connecting ball.

When the electronic device is used, after the electronic device is connected to the device connecting member 60, the angle of the device connecting rod 20 with respect to the stretching rod 12 and the telescopic length of the stretching rod 12 with respect to the fixing rod 11 can be respectively adjusted through the operations described above until the electronic device is adjusted to a proper position and angle. If the electronic equipment bracket capable of being adjusted in multiple degrees of freedom is attached to the back of the vehicle-mounted display screen through the attachment piece 50, the plane of the electronic equipment can be adjusted to be coplanar with the vehicle-mounted display screen due to the fact that the attachment piece 50 and the equipment connecting piece 60 are arranged on the same side, the electronic equipment can be checked at the same time, and convenience and safety are greatly improved.

When the electronic apparatus is not used, the stretching rod 12 is retracted into the fixing rod 11 after the electronic apparatus is removed. Then, the angle of the equipment connecting rod 20 is changed, because the attachment 50 and the equipment connecting piece 60 are arranged on the same side, and the lengths of the equipment connecting rod 20 and the fixed rod 11 are basically equal, the equipment connecting rod 20 can rotate around the axis to be attached to the fixed rod 11, so that the storage effect that the equipment connecting rod 20 and the support rod 10 are folded in half is formed. If the multi-freedom-degree adjustable electronic equipment bracket is attached to the back of the vehicle-mounted display screen through the attachment 50, the whole multi-freedom-degree adjustable electronic equipment bracket can be completely shielded by the vehicle-mounted display screen, and the visual effect is greatly improved.
