[0028] The lock connection structure and the electronic device protective case have simple structures and are easy to install. During installation, the locking clip in the second connection part is controlled to remain in a released state by the toggle component, and then the clamping block on the first connection part is inserted into the installation groove in the second connection part. At this time, the user controls the locking clip in the second connection part by the toggle component to clamp and fix the clamping block and keep it in a locked state to fix the first connection part and the second connection part. The operation is simple, installation can be achieved without the aid of external tools, and the user experience is better.

[0029] Furthermore, the locking clip 13 includes two clamping arms 131 rotatably arranged in the installation groove 121; the two clamping arms 131 are pivotally connected to each other through a connecting shaft 122; the connecting shaft 122 is fixedly installed in the installation groove 121, and the two clamping arms are positioned by the connecting shaft, which can not only ensure that the two clamping arms rotate on the same center of a circle, but also prevent the locking clip 13 from arbitrarily deviating in the installation groove 121; a clamping portion 1311 and a triggering portion 1312 are respectively provided at both ends of the clamping arm 131; a clamping portion 1313 extending toward the clamping block 111 is provided on the clamping portion 1311; in one embodiment, the thickness of the clamping portion 1313 is less than the thickness of the clamping arm 131; and a clamping groove 1111 that cooperates with the clamping portion 1313 is provided on the clamping block 111.

[0030] In order to make the locking clip lock the clamping block more stably, a reset elastic member 15 that provides elastic force to the toggle assembly 14 is further provided in the installation groove 121; it is worth noting that the reset elastic member 15 is a reset spring in the prior art; the reset elastic member 15 is located at the end of the toggle assembly 14 away from the locking clip 13; one end of the reset elastic member 15 is connected to the toggle assembly 14, and the other end abuts against the inner side wall of the installation groove 121 away from the first connecting portion; Figure 2 As shown, when the toggle assembly controls the locking clip to be in the released state, the reset elastic member is in the compressed state, and the locking clip 13 is not in contact with the clamping block 111; Figure 3 As shown, when the toggle assembly controls the locking clip to be in a locked state, the reset elastic member resets and provides a force to the toggle assembly in the direction of the locking clip so that the locking clip maintains the purpose of locking the clamping member, and the connection is firm.

[0031] Furthermore, the toggle assembly 14 includes a slider 141 that approaches or moves away from the locking clip 13 along the mounting groove 121, a top block 142 disposed between the two trigger portions 1312, and a fixing claw 143 disposed on the outside of the two trigger portions 1312; the top block 142 gradually expands from the outside to the inside; in the process of the toggle assembly 14 approaching the locking clip 13, the top block 142 drives the two clamp arms 131 to expand outward; when the toggle assembly 14 moves away from the locking clip 13, the top block 142 moves away from the locking clip 13, and the fixing claw 143 drives the two clamp arms 131 to close together, and the structural design is ingenious.

[0032] In one embodiment, if Figure 2 and Figure 3 As shown, two clamping blocks 111 are provided; the locking clip 13 is movably provided between the two clamping blocks 111; when the top block 142 drives the two clamping arms 131 to expand outwardly, the two clamping blocks 1313 are respectively inserted into the two clamping slots 1111. Figure 4 As shown, one clamping block 111 is provided, and the clamping block 111 is located between the two clamping portions 1311. When the top block 142 drives the two clamping arms 131 to close together, the two clamping blocks are respectively inserted into the two clamping slots; the use is flexible.

[0033] Optionally, the slider 141, the top block 142 and the fixing claw 143 are integrally connected; the fixing claw 143 includes two limiting arms 1431 respectively arranged on both sides of the top block 142; a movable space 144 for the trigger part 1312 to rotate is provided between the top block 142 and the limiting arms 1431; the two movable spaces 144 are connected.

[0034] Furthermore, the outer surface of the second connecting portion 12 is also provided with a through hole 123 corresponding to the toggle assembly 14 and connected to the mounting groove 121; the toggle assembly 14 also includes a hand-shift block 145 that drives the top block 142 and the fixing claw 143 to move forward and backward along the through hole 123; at least a part of the hand-shift block 145 protrudes out of the through hole 123; when in use, the hand-shift block 145 can be moved by toggling the hand-shift block 145 with a finger to drive the toggle assembly 14 to move, thereby controlling the locking clip to lock the clamping block or release the clamping block, which is easy to use.

[0035] Furthermore, the cross section of the mounting groove 121 is a trapezoidal structure; the outer surface of the clamping block 111 and the outer surface of the fixing claw 143 are both provided with inclined surfaces that match and fit the inner wall of the mounting groove 121; the connection is stable.
