SUMMARY OF THE INVENTION In view of the above situation, it is necessary to provide a lock-type locking device that is not easy to fall off. It includes a locking member and a supporting sleeve. The locking member has a locking portion and a rod connected to the locking portion. a portion of the branch having a larger outer diameter than the shank of the shank: the yoke is used to support the locking member, the through hole includes: a perforated hole wall and the The limiting portion connected to the first hole segment, the locking portion of the locking member can enter the through portion and can be reversely restricted by the limiting portion. The above-mentioned locks are placed in the locking process by the above-mentioned locks. Since the branch sleeve has a -limit portion, when the lock portion of the lock member is in the through hole, it can be blocked by the limit portion. It does not directly go out of the support sleeve = limit = during the locking and fixing process, the lock member can be prevented from being lost from the support sleeve. Therefore, the above-described lock device has a tendency to be easily detached. [Embodiment] The lock of the present invention will be described in detail with reference to the accompanying drawings and embodiments. The device is made. Referring to Figures 2 and 3', the apparatus of the present invention can be used to lock components on a lock-up housing made of metal or plastic. The locking device 2 includes a member such as a computer μ mouth member 22, a support sleeve 24 7 1322855 and an elastic member 26. The support sleeve 24 is used for the locking device 20 to lock and fix two of the above components. The locking member 22 is supported thereon to prevent the locking member 22 from being lost, and if necessary, the supporting sleeve 24 can also be The two components that need to be fixed to each other are separated by a certain distance to facilitate heat dissipation. One end of the lock member 22 has a locking portion 222. The support sleeve 24 has a uniform bore 242 having a first bore section 2422 defining a finite portion 244. The movement of the locking portion 222 through the limiting portion 244 in the Y1 direction can be restricted from the support sleeve 24 in the Y2 direction by the limiting portion 244, or the locking portion 222 can require an external force after passing through the limiting portion 244. The action can be moved out from the support sleeve 24 in the Y2 direction, that is, the limiting portion 244 can reversely limit the locking portion 222. The depth of the through hole 242 of the support sleeve 24 may be greater than, equal to, or smaller than the length of the lock member 22, preferably the depth of the through hole 242 of the support sleeve 24 is greater than or equal to the length of the lock member 22, so that the support sleeve 24 can be The locking member 22 is better protected. In the present embodiment, the locking portion 222 is a stud having an external thread. The lock member 22 is further provided with a head portion 226 at the other end opposite to the lock portion 222, and a rod portion 224 connecting the lock portion 222 and the head portion 226. The maximum diameter of the latch 222 is greater than the diameter of the stem 224 and less than the diameter of the head 226. The through hole 242 includes a first hole segment 2422, a second hole segment 2424, and a third hole segment 2426 that are sequentially adjacent. The diameter of the first hole segment 2422 is greater than or equal to the diameter of the head portion 226 of the locking member 22. The diameter of the second hole portion 2424 is smaller than the diameter of the head portion 226 of the locking member 22 and is greater than the locking portion of the locking member 22, respectively. 222 and the diameter of the rod portion 224; the diameter of the third hole portion 2426 is smaller than the diameter of the second hole portion 2424 and is greater than or equal to the diameter of the locking portion 222 of the locking member 22 and the diameter of the rod portion 224 of the 8 1322855, and the third hole portion The length of 2426 is preferably greater than or equal to the length of the latch 222. An inner threaded hole is formed in the limiting portion 244 to match the thread of the locking portion 222. The limiting portion 244 is located between the second bore section 2424 and the third bore section 2426 and has a minimum aperture smaller than the maximum diameter of the latching portion 222. In addition, a flange 246 is formed in the outer wall of the first bore section 2422 away from the second bore section 2424. The elastic member 26 can be a spring having an outer diameter greater than a minimum aperture of the limiting portion 244, the inner diameter being greater than the diameter of the locking portion 222 of the locking member 22 and the diameter of the stem portion 224, respectively, but smaller than the diameter of the head portion 226 of the locking member 22. During use, when the elastic member 26 is placed in the through hole 242 and the locking member 22 penetrates into the elastic member 26, the two ends of the elastic member 26 can respectively abut against one end of the limiting portion 244 and the head portion 2 26 . The locking device 20 can firstly fit the elastic member 26 into the through hole 242 of the supporting sleeve 24 during the assembly process, so that one end of the elastic member 26 abuts against one end of the limiting portion 244; then the locking member 22 is locked. The portion 222 extends through the elastic member 26 and rotates so that the thread on the locking portion 222 cooperates with the thread on the limiting portion 244 to cause the locking portion 222 to pass through the limiting portion 244. After the assembly of the closure device 20 is completed, it can be used to lock and fix more than two components. Referring to FIG. 4, when the locking device 20 is used, the assembled locking device 20 can be first loaded into the mounting hole 282 of the component 28, and the locking device 20 and the component 28 are fixed to each other; and then the rotary locking is used. The head 226 of the member 22 engages the latching portion 222 from the third bore portion 2426 with other components (not shown) to lock and secure the two or more components. Need to say 9 丄 like 855 • It is used that the hole diameter of the mounting hole 282 is preferably smaller than the flange plus the outer wall straight - the flange 246 can be riveted into the mounting hole 'question sleeve 24 and the component 28 The bond between the two. • The locking portion fixing process ′′ passes through the locking sleeve 24 limiting portion 244 I due to the locking portion 222 of the locking member 22, and the limiting portion 244 can be directly removed from the supporting sleeve 24 The middle disengagement, that is, the locking portion 222 needs to perform a reverse condensing movement and form a threaded engagement with the limiting portion 244 to be able to exit along the · · = = , , , , , , , , , , , , , , , , , , , , Rotating into the limiting portion 244 to achieve a threaded engagement, the external thread of the external thread on the limiting portion 244 is locked; the =Y2 direction is withdrawn from the limiting portion, so that the locking is fixed; It is ensured that the locking member 22 is prevented from being detached from the supporting sleeve 24 to ensure the smooth progress of the locking and fixing process. When two or more components two or two IT two 'detachment Γ locks 222 can still be held on the support sleeve 2, the loss of the lock member 22 is avoided, which makes it difficult to reassemble. This = in: unit 2. It can be fixed to the component 28, so that it is not easy to fall off and lose in terms of the lock and the body, thereby avoiding the difficulty of the process. Further, since the locking device 2 is provided with two; the garment can be supported by the elastic member 26, preventing the locking member 22 from sagged in the third hole portion 26 of the supporting sleeve 24 before the two or more members of the locking opening, thereby It can bring convenience to the locking process. It can be understood that the above-mentioned locking device can also have a structure in which the lock is a structure other than a stud, for example, a groove. The limiting dam portion 244 can be provided with other structures than the thread. For example, the hole wall 1322855 is formed with a tortuous path so that the locking portion 222 needs to perform a curved motion to pass; or an elastic barb is formed on the hole wall, and the lock is made by pushing The locking portion 222 of the fitting '22 passes therethrough; or a rib is formed on the wall of the hole, and the limiting portion 244 is inflated by heating the supporting sleeve 24 to pass the locking portion 222; or the locking portion is firstly engaged The 222 passes through the limiting portion 244, and then a bump is formed on the limiting portion 244 to restrict the locking portion 222 from exiting. Moreover, it will be appreciated that the resilient member 26 in the latching device 20 can be omitted; even any two of the first bore segment 2422, the second bore segment 2424 and the third bore segment 2426 can be omitted. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and those skilled in the art will be equivalently modified or changed in the spirit of the invention.
