As shown in FIG. 1 and FIG. 2 , the locking mechanism M mainly includes a housing 100 , a frame 200 , a fixing element 300 , a nut element 400 , and a locking element 500 .

The casing 100 includes a plane 110 , and the plane 110 generally has a plate-like structure. The frame 200 is fixed on the plane 110 of the casing 100 and has a receiving hole 210 . It should be noted that the aforesaid accommodating hole 210 can be divided into a first section 211 and a second section 212, and the first section 211 is located between the second section 212 and the plane 110 of the housing 100 . The first section 211 has a first width W1, the second section 212 has a second width W2, and the first width W1 is greater than the second width W2. Therefore, the accommodating hole 210 may form an inverted T-shaped structure.

The fixing element 300 is fixed on the plane 110 of the housing 100 and accommodated in the accommodation hole 210 of the frame 200 . The fixing element 300 may have substantially the same appearance as the receiving hole 210 of the frame 200, in other words, the fixing element 300 may have a first part 310 and a second part 320 connected to each other, and the first part 310 is accommodated in the receiving hole. In the first section 211 of 210 , the second portion 320 is accommodated in the second section 212 of the accommodating hole 210 , and the width of the first portion 310 is greater than the second width W2. In this embodiment, the width of the first portion 310 is approximately the same as the first width W1, and the width of the second portion 320 is approximately the same as the second width W2.

The fixing element 300 has an external screw hole 330 . In this embodiment, the external screw hole 330 can extend from the second portion 320 of the fixing element 300 to the first portion 310 , that is, it can go through the entire fixing element 300 . The thread of the external screw hole 330 is mainly formed at the second portion 320 , and no thread may be formed on the plane of the external screw hole 330 of the first portion 310 . The width of the external screw hole 330 in the second portion 320 may be greater than the width of the external screw hole 330 in the first portion 310 .

When the user wants to release the fixation of the part C, the user can unscrew the locking element 500 out of the inner screw hole 430 to separate from the nut element 400, so that the fixation of the part C can be released to move the aforementioned part C. Since the thread direction of the inner screw hole 430 is opposite to the thread direction of the outer screw hole 330 on the fixing element 300, when the user unscrews the locking element 500, the nut element 400 will be more tightly combined with the fixing element 300, and will not A situation occurs where the locking element 500 and the nut element 400 rotate simultaneously and the locking element 500 cannot be unscrewed. In this embodiment, the locking element 500 may include a screw.

The installation method of the locking mechanism M will be described below. Please refer to FIG. 4A and FIG. 4B , firstly, the glue H can be disposed on the plane 110 of the casing 100 , and the fixing element 300 can be disposed on the glue H. The frame 200 can then be disposed on the glue H and the fixing element 300 is accommodated in the receiving hole 210 of the frame 200 .

As shown in FIG. 4C , then, the frame 200 and the fixing element 300 can be fixed on the casing 100 by means of thermal bonding (thermal bonding) with the adhesive H. Since the groove 201 and the groove 301 are respectively formed on the surface of the frame 200 and the fixing element 300 facing the plane 110 , excess glue H can enter into the groove 201 , 301 .

As shown in FIG. 4D, after the frame 200 and the fixing element 300 are fixed on the casing 100, the user can use an external tool (such as a wrench) to rotate the nut element 400 into the fixing element 300 along a first direction. In the external screw hole 330.

As shown in FIG. 4E, finally, the user can place the part C to be fixed on the operating portion 420 of the nut element 400, and then use an external tool (such as a screwdriver) to rotate the locking element 500 along a second direction screwed into the internal screw hole 430 of the fixing element 300, wherein the first direction is opposite to the second direction.

Please refer to FIG. 5A, when the inner screw hole 430 is damaged due to grinding or improper operation when locking the locking element 500, the user can use an external tool (such as a wrench) to unscrew the nut element 400 out of the fixing element 300 External screw holes 330 .

Next, as shown in FIG. 5B , the user can use an external tool (such as a wrench) to screw a new nut element 400' into the external screw hole 330 of the fixing element 300. In other words, through the aforementioned structure of the locking mechanism M, it is beneficial for the user to replace the nut element 400 with the damaged inner screw hole 430, without causing the entire electronic device E to be scrapped or require a lot of trouble to disassemble due to a single screw hole being damaged. electronic device E.
