The second oblique tongue guide post 722 passes through the bracket assembly 170, the first waist-shaped hole 812 and the first top plate 720, so that the first scissor tongue platform 810, the bracket assembly 170 and the first top plate 720 are connected together. When the scissor tongue assembly 800 moves, the second oblique tongue guide post 722 can slide within the first waist-shaped hole 812 to cause the second elastic member 811 to expand and contract, thereby realizing the reciprocating motion of the scissor tongue assembly 800. The second elastic member 811 can be configured as a spring.

[0076] Optionally, a first through hole is provided on the side of the second scissor tongue platform 820 away from the first top plate 720, and a first scissor tongue 830 and a second scissor tongue 840 are provided side by side on the side of the second scissor tongue platform 820 away from the first top plate 720. A second through hole and a third through hole are provided on the first scissor tongue 830 and the second scissor tongue 840 respectively. The first through hole, the second through hole and the third through hole are connected together by an oblique tongue pin 724. The through hole portion 140 includes a scissor tongue hole 141, and the first scissor tongue 830 and the second scissor tongue 840 extend outward in a cross shape through the scissor tongue hole 141.

[0077] The first shear tongue 830 has a vertical surface and a circular arc surface. The vertical surface is perpendicular to the guide plate 120, and the circular arc surface is connected to the vertical surface. The length of the vertical surface is equal to the length of the shear tongue hole 141, so that when the first shear tongue 830 rotates around the latch bolt 724, the vertical surface just retracts into the shear tongue hole 141. The first shear tongue 830 can rotate counterclockwise, that is, in the closed state, the second elastic member 811 is in the normal state, and the first shear tongue 830 is located in the hole of the door frame. In the open state, the second elastic member 811 is in the normal state, and the first shear tongue 830 extends out of the shear tongue hole 141. When the door is opened inward and not fully opened, the first shear tongue 830 is pressed by the non-hole part of the door frame, and the first shear tongue 830 rotates counterclockwise, and the vertical surface just retracts into the shear tongue hole 141.

[0078] Similarly, the second shear tongue 840 has the same structure as the first shear tongue 830, except that the second shear tongue 840 is a mirror image of the first shear tongue 830. It is easy to think that when the first shear tongue 830 can rotate clockwise, that is, when the door is opened outward and not fully opened, the second shear tongue 840 is pressed by the non-hole part of the door frame, and the second shear tongue 840 rotates clockwise, and the vertical surface just retracts into the shear tongue hole 141.

[0079] In this way, the shear tongue assembly 800 can enable the electric lock to realize both inward and outward opening functions, increasing the diversity of use of the electric lock.

[0080] Optionally, as shown in Figure 21 The shear tongue assembly 800 can also be replaced by a latch bolt assembly 860. The latch bolt assembly 860 is identical to the shear tongue assembly 800, except that the first shear tongue 830 and the second shear tongue 840 are replaced by a first latch bolt 861. The first latch bolt 861 is sleeved on the latch bolt, and has a symmetrical structure in the form of a symmetrical triangle, so that the first latch bolt 861 can only realize inward opening. The symmetrical structure makes the first latch bolt 861 more uniform in force and less prone to damage.
