[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Example 1: Please refer to Figure 1-4 In the present embodiment, an anti-stuck plane lock comprises a plane lock 1 and a groove 4. The upper and lower sides of the front side of the plane lock 1 are respectively connected with the grooves 4. How to operate and use the plane lock 1 is already the prior art and will not be elaborated on. The inner wall of the groove 4 is connected with a mounting structure 2. The front side of the plane lock 1 is slidably connected with a bent rod 3. The bent rod 3 is subjected to force and slides up and down through the inside of the slide groove on the front side of the plane lock 1. A first inclined block 5 is fixedly connected to the bottom of the bent rod 3, and a second inclined block 6 is fitted to the bottom of the first inclined block 5.

[0020] The mounting structure 2 includes a screw 201 and a ring 202. The outer wall of the screw 201 is slidably engaged with the inner wall of the groove 4. The screw 201 is subjected to force to slide up and down through the slide groove of the inner wall of the groove 4. The outer wall of the screw 201 is threadedly connected with the inner wall of the ring 202. The ring 202 is subjected to force to rotate forward and backward through the outer wall of the screw 201. The rear end face of the screw 201 is fixedly connected with a vertical plate 203.

[0021] The vertical plate 203 in the installation structure 2 is located inside the opening of the door body, and then the ring 202 rotates forward on the outer wall of the screw 201 to make the ring 202 disengage from the inside of the groove 4, and then the screw 201 slides outward on the inner wall of the groove 4, thereby driving the vertical plate 203 to move outward, so that the vertical plate 203 is engaged with the opening at the connection between the vertical plate 203 and the door body, and then the ring 202 is rotated backward to make the rear end face of the ring 202 press against the inner wall of the groove 4, thereby completing the fixation of the plane lock 1, facilitating the installation of the anti-jamming plane lock and reducing the difficulty of operating the anti-jamming plane lock.

[0022] The inner wall of the second oblique block 6 is slidably connected with a straight rod 7, and the second oblique block 6 slides forward and backward through the outer wall of the straight rod 7 under force, the front of the straight rod 7 is fixedly connected to the front of the inner wall of the plane lock 1, and the outer wall of the straight rod 7 is sleeved with a spring 8, and the two ends of the spring 8 are respectively fixedly connected to the front of the second oblique block 6 and the front of the inner wall of the plane lock 1. After the second oblique block 6 is forced to move forward, it rebounds by the elastic force of the spring 8, and a vertical plate 9 is fixedly connected to the rear of the bottom of the second oblique block 6.

[0023] Working principle:

[0024] When using the plane lock 1, first make the connection between the plane lock 1 and the door body fit, at this time the vertical plate 203 is located inside the opening of the door body, then the ring 202 rotates forward on the outer wall of the screw 201, so that the ring 202 is separated from the inside of the groove 4, and then the screw 201 slides outward on the inner wall of the groove 4, thereby driving the vertical plate 203 to move outward, so that the vertical plate 203 is engaged with the opening at the connection between the door body, and then the ring 202 is rotated backward so that the rear end surface of the ring 202 is tightly pressed against the inner wall of the groove 4, completing the fixation of the plane lock 1. When the key is inserted into the plane 1, the rear end of the key fits against the front bottom of the vertical plate 9. After the key is stuck in the inside of the plane lock 1, the bent rod 3 is pushed downward, thereby driving the first inclined block 5 to move downward, so that the second inclined block 6 moves forward on the outer wall of the straight rod 7. The moved second inclined block 6 drives the vertical plate 9 to move forward, thereby pushing the key to move forward to avoid getting stuck. After the end, the spring 8 provides a rebound force to move the second inclined block 6 backward back to its original position.

[0025] Example 2: Please refer to Figure 1-4 In the present embodiment, an anti-stuck plane lock further comprises a protective pad 10, the front side of the protective pad 10 is fixedly connected to the outer side of the rear end face of the plane lock 1.

[0026] Working principle:
