[0040] 1. Housing; 2. Connecting rod; 3. Mounting bracket; 4. Moving part; 6. Connecting assembly; 9. Limiting pin; 8. Inner shell; and 10. Fixing assembly.

[0041] The mounting bracket 3 is installed on one side inside the housing 1, and the connecting rod 2 is disposed inside the mounting bracket 3;

[0042] The movable part 4 is disposed inside the housing 1, and a rectangular limiting groove 5 and a circular through hole 12 are respectively opened on the left and right sides of the surface of the movable part 4.

[0043] The limiting pin 9 is plugged into the interior of the circular through hole 12;

[0044] The connecting component 6 is disposed between the movable part 4 and the housing 1;

[0045] One end of the housing 1 is connected to the outer shell 7, and the inner shell 8 is disposed between the housing 1 and the outer shell 7;

[0046] The fixing component 10 is disposed between the limiting pin 9 and the inner shell 8.

[0047] A coil spring 11 is fitted onto the surface of the connecting rod 2.

[0048] The use of coil spring 11 can squeeze and fix the movable part 4, and can reset the movable part 4 after it is pushed. The opening of through groove 14 facilitates the movement of movable part 4. The use of rectangular limit groove 5 facilitates the connection of triangular block 62. Mounting bracket 3 is installed on one side of inner wall of housing 1 by bolts. Circular through hole 12 facilitates the installation of limit pin 9. Mounting through hole is opened on the top of inner shell 8 to facilitate the installation of limit pin 9 and fastener 101.

[0049] The connecting component 6 includes a connecting plate 61, a triangular locking block 62, and a pin 63. The triangular locking block 62 is connected to the center position of one side of the surface of the connecting plate 61, and the pin 63 is connected to one side of the surface of the connecting plate 61.

[0050] The fixing component 10 includes a fixing member 101 and a fixing bolt 102. The fixing member 101 is disposed on the top of the inner shell 8, and the fixing bolt 102 is disposed between the fixing member 101 and the inner shell 8.
