[0077] A locking plate paddle 7, wherein the locking plate paddle 7 is used to drive the quick lock member 3 to slide relative to the angle block 2 along the axial direction of the rotating shaft 6;

[0078] Specifically, the locking plate paddle 7 can be rotatably arranged on the base 1 or the angle block 2, and by toggling one end of the locking plate paddle 7, the other end thereof that cooperates with the quick lock member 3 can drive the quick lock member 3 to slide; the base 1 is fixed on a display unit 200, and the locking rod 8 is fixed on another display unit 200. In this embodiment, the locking hole 32 is a variable diameter hole, and the locking rod 8 includes a non-circular locking head that cooperates with the variable diameter hole. When the locking rod 8 that cooperates with the paddle-type angle lock 300 passes through the locking hole 32 and the through hole 21, by toggling the locking plate paddle 7, the locking head of the locking rod 8 can be locked or unlocked.

[0079] It is easy to understand that in some other embodiments, the first elastic member 5 may not be provided. In this case, the user may manually reset the quick lock member 3 through the lock piece paddle 7 .
