Anti-dismantling screw 4 comprises a head portion 41 and a rod portion 42, wherein the rod portion 42 comprises a first optical axis segment 421, a threaded segment 422 and a second optical axis segment 423 which are sequentially arranged, the rod portion 42 is connected with the head portion 41 through the first optical axis segment 421, the rod portion 42 can penetrate through a threaded hole 312 and an optical hole 313, the second optical axis segment 423 is inserted into the first connecting hole 21, and the length of the first optical axis segment 421 is greater than that of the threaded hole 312. When the second optical axis segment 423 is inserted into the first connection hole 21, the threaded segment 422 is disengaged from the threaded hole 312 and positioned in the optical hole 313, and the second locking member 2 is locked to the first locking member 1. When the second optical axis segment 423 is disengaged from the first coupling hole 21, the locking between the second locking member 2 and the first locking member 1 is released.

It is understood that the first optical axis segment 421 and the second optical axis segment 423 refer to portions of the anti-detach screw 4 without threads on the outside.

In the installation process of the anti-dismantling structure, the anti-dismantling support 3 is fixedly arranged on the first locking piece 1; then the anti-dismantling screw 4 is installed in the second connecting hole 31, and the second optical axis segment 423 of the anti-dismantling screw 4 firstly passes through the threaded hole 312 of the anti-dismantling bracket 3; then, screwing the anti-disassembly screw 4 to enable the thread section 422 of the anti-disassembly screw 4 to spirally penetrate through the thread hole 312 of the anti-disassembly bracket 3; then the first connecting hole 21 of the second locking piece 2 is correspondingly arranged with the second connecting hole 31 of the anti-dismantling bracket 3; after the threaded section 422 completely passes through the threaded hole 312, since the length of the first optical axis section 421 is greater than that of the threaded hole 312, the anti-tamper screw 4 is continuously pushed, so that the anti-tamper screw 4 continues to slide for a certain distance towards the first connection hole 21 until the head 41 of the anti-tamper screw 4 stops at one end of the assembly hole 311 close to the threaded hole 312; at this time, the shaft 42 of the removal-preventing screw 4 is inserted into the first coupling hole 21, and the second locking member 2 is locked to the first locking member 1.

When the locking between the second locking member 2 and the first locking member 1 is released, a disassembling tool (such as a screwdriver or an allen wrench) is firstly used for abutting against one end, away from the threaded section 422, of the second optical shaft section 423 of the anti-disassembling screw 4; pushing the anti-dismantling screw 4 for a distance towards the direction far away from the first connecting hole 21 until the thread section 422 of the anti-dismantling screw 4 abuts against the thread hole 312 of the anti-dismantling support 3; then, the anti-disassembly screw 4 is screwed, so that the thread section 422 of the anti-disassembly screw 4 is screwed into the thread hole 312 of the anti-disassembly bracket 3 towards the direction far away from the first connecting hole 21; when the second optical axis segment 423 of the tamper screw 4 exits the first coupling hole 21, the locking between the second locking member 2 and the first locking member 1 is released.

As can be seen from the above, in the process of releasing the locking between the second locking member 2 and the first locking member 1, the anti-tamper screw 4 is pushed a distance toward the direction away from the first connection hole 21 until the threaded section 422 of the anti-tamper screw 4 abuts against the threaded hole 312 of the anti-tamper bracket 3, and then the anti-tamper screw 4 is screwed, so that the second optical axis section 423 of the anti-tamper screw 4 can exit from the first connection hole 21. That is, neither directly screwing the tamper screw 4 nor simply pushing the tamper screw 4 in a direction away from the first connection hole 21 can cause the shaft portion 42 of the tamper screw 4 to exit the first connection hole 21. So set up, the dismantlement of anti-tear screw 4 becomes comparatively complicated, has improved the dismantlement degree of difficulty of anti-tear structure, therefore has solved the current structure of preventing tearing open comparatively simply and the problem that the degree of difficulty is low of preventing tearing open.

The length of the first optical axis segment 421 is greater than that of the screw hole 312, and the detachment prevention structure further includes an elastic member 5, the elastic member 5 being coupled to the detachment prevention screw 4 to apply a force to the detachment prevention screw 4 moving toward the screw hole 312 from the fitting hole 311 so that the second optical axis segment 423 has a tendency to move toward the first coupling hole 21. With the arrangement, in the process of releasing the locking between the second locking piece 2 and the first locking piece 1, the elastic action of the elastic piece 5 is overcome, and the disassembly difficulty of the anti-disassembly structure is further increased.

In an embodiment, as shown in fig. 1, the anti-detaching structure further includes a stopper 6, the stopper 6 is disposed on a side of the mounting hole 311 away from the threaded hole 312, and two ends of the elastic member 5 abut against the stopper 6 and the head 41, respectively. The elastic member 5 may be a compression spring, and the stop member 6 is disposed at an end of the assembly hole 311 away from the threaded hole 312, and can provide sufficient supporting force for the compression spring, so that the compression spring applies a force to the tamper screw 4 to move from the assembly hole 311 toward the threaded hole 312, so that the second optical axis segment 423 has a tendency to move toward the first connection hole 21.

In one embodiment, as shown in FIG. 1, the stop member 6 comprises a stop plate mounted to an end of the mounting hole 311 remote from the threaded hole 312 by a fastener. After the elastic member 5 is installed in the assembly hole 311, a baffle plate is directly installed at one end of the assembly hole 311 far away from the threaded hole 312 through a fastener, and the baffle plate can provide a supporting force for the elastic member 5. So set up, the assembly and the dismantlement of stop member 6 can be both more simple and convenient.

In one embodiment, as shown in FIG. 1, the aperture of the mounting hole 311 is larger than the aperture of the threaded hole 312. In this way, a stepped structure is formed between the attachment hole 311 and the screw hole 312, and the head 41 of the tamper screw 4 is stopped in the stepped structure. So set up, be convenient for prevent tearing open screw 4 and prevent tearing open the assembly of support 3.

In one embodiment, as shown in fig. 1, the second optical axis segment 423 of the tamper-proof screw 4 is provided with a mounting hole 424, and the mounting hole 424 is provided on an end surface of an end of the second optical axis segment 423 away from the threaded segment 422. So set up, when dismantling anti-disassembly screw 4, utilize the extracting tool to insert mounting hole 424 to the extracting tool drives anti-disassembly screw 4 and moves together, can make second optical axis section 423 withdraw from first connecting hole 21, thereby releases the locking between second locking part 2 and the first locking part 1.
