The connecting assembly 200 is provided with a latch groove 2110, and the locking device 100 is connected with the connecting assembly 200 by snapping the latch hook 20 into the latch groove 2110. Since the connection assembly 200 is connected to the electronic device, the locking device 100 can be connected to the electronic device through the connection assembly 200.

Referring to fig. 14, in some embodiments, the connection assembly 200 includes a base 2100 and a fastener 2200. The base 2100 has a substantially block shape, the engaging groove 2110 is provided in the base 2100, and the base 2100 is connected to the electronic device by the fastening member 2200. Specifically, the base 2100 and the electronic device are provided with mounting holes 2120 and the mounting holes of the electronic device are provided with internal threads, and the fasteners 2200 are inserted through the mounting holes 2120 of the base 2100 and are in threaded connection with the mounting holes 2120 of the electronic device. Fasteners 2200 include, but are not limited to, screws and bolts.

Referring to fig. 14, in some embodiments, the connection assembly 200 further includes a buffer pad 2300 and a magnetic member 2400, the buffer pad 2300 is sandwiched between the base 2100 and the electronic device, and since the buffer pad 2300 can be elastically deformed, the buffer pad 2300 sandwiched between the base 2100 and the electronic device can fill a gap between the base 2100 and the electronic device, so that the base 2100 and the electronic device can be tightly combined under the connection of the fastener 2200. Moreover, the buffer 2300 interposed between the base 2100 and the electronic device can prevent the base 2100 from directly contacting the electronic device to scratch the electronic device. The material of the buffer pad 2300 includes but is not limited to elastic materials such as silica gel, sponge, rubber, etc.

The magnetic member 2400 is connected to the base 2100, specifically, the magnetic member 2400 may be embedded in the base 2100 or disposed on a surface of the base 2100 facing the cushion pad 2300, the magnetic member 2400 attracts the locking device 100, when the connecting assembly 200 is connected to the electronic device, the locking device 100 is connected to the connecting assembly 200 through the latch hook 20, and the magnetic member 2400 and the locking device 100 are attracted by magnetic force, so that the connection strength between the locking device 100 and the connecting assembly 200 can be increased.

The receiving cavity 110 may also be correspondingly provided with a magnet (not shown), and the magnet is arranged corresponding to the connecting assembly 200 to attract the connecting assembly 200, so that the connecting strength of the locking device 100 and the connecting assembly 200 can be increased.

When installing, firstly, the fastener 2200 is inserted into the base 2100 and aligned with the mounting hole 2120 of the electronic device, and then the fastener 2200 is screwed into the mounting hole 2120 of the electronic device, since the rubber ring 2600 is extruded and deformed during screwing the fastener 2200 and generates a friction force in a circumferential direction, an installer can rotate the fastener 2200 together with the base 2100 and screw the fastener into the mounting hole 2120 of the electronic device only by rotating the base 2100.

As the base 2100 rotates, the base 2100 presses the buffer pad 2300, and the buffer pad 2300 generates a dynamic friction force between the base 2100 and the electronic device, and the dynamic friction force gradually increases as the base 2100 rotates. When the dynamic friction exceeds the static friction between the rubber ring 2600 and the fastening member 2200, the fastening member 2200 is overloaded and rotates relative to the base 2100 (i.e., the base 2100 is rotated and the fastening member 2200 is not screwed into the mounting hole 2120 of the electronic device), and the relative position between the base 2100 and the electronic device is adjusted to overlap the base 2100 and the electronic device to complete the pre-mounting.

In the pre-installation process, the base 2100 is connected to the electronic device to a certain extent through the fastener 2200, and then the fastener 2200 is continuously screwed by using a screwdriver or a wrench, so that the fastener 2200 is screwed into the preset position, and the connection between the base 2100 and the electronic device can be completed. The locking device 100 is connected to the base 2100 of the connecting assembly 200 through the locking hook 20, so as to connect the quick release apparatus 1000 to the electronic apparatus.
