For example, in the gap or in the hole, the locking screw 16 may fall into the [invention]. In the above situation, it is necessary to set it up. The lock is assembled and has a ::: device comprising a locking member and a supporting sleeve, the locking member having: a lever portion connected to the thin portion, the supporting sleeve and the toothed towel (4) The Puhai support sleeve having an outer diameter larger than the rod portion is used for binding the lock member, the through hole includes a first hole & and a (four) joint on the wall of the through hole and connected to the first hole portion The locking portion of the piece can enter the through hole, and the locking portion can be reversely restricted by the limiting portion after passing through the limiting portion. The locking device is through the through hole of the supporting sleeve during the locking process. Having a limiting portion, when the locking portion of the locking member is limited by the support sleeve The limiting portion blocks without being detached directly from the supporting sleeve, so that the locking member can be prevented from falling off from the supporting sleeve and lost during the locking and fixing process. Therefore, the above locking device has the advantage of being difficult to fall off. BEST MODE FOR CARRYING OUT THE INVENTION The locking device of the present invention will be described in detail in the following with reference to the accompanying drawings and embodiments. Referring to the drawings 2 and 3', a locking device 20 according to a preferred embodiment of the present invention can be used for locking. A component made of metal or plastic, such as an element on the housing. The locking device 20 includes a locking member 22, a support sleeve 200912153, and an elastic member 26. The support sleeve 24 is used for locking the locking device 20. Before the two components are fixed, 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 separate the two components to be fixed to each other by a certain distance. One end of the locking member 22 has a locking portion 222. The supporting sleeve 24 has a permanent through hole 242, and the through hole 242 has a first hole portion 2422, and a limiting portion 244 is formed on the hole wall. Y1 direction movement through the limit portion 244 It can be restricted by the limiting portion 244 to directly withdraw from the support sleeve 24 in the Y2 direction, or the locking portion 222 needs an external force after passing through the limiting portion 244 to move out from the support sleeve 24 in the Y2 direction. That is, the limiting portion 244 can reverse the limiting locking portion 222. The depth of the through hole 242 of the supporting sleeve 24 can be greater than, equal to, or smaller than the length of the locking member 22, preferably the depth of the through hole 242 of the supporting sleeve 24 is greater than or It is equal to the length of the locking member 22, so that the supporting sleeve 24 can better protect the locking member 22. In the present embodiment, the locking portion 222 is a stud having an external thread. The locking member 22 is at the locking portion 222. The other end is also provided with a head 226 and a rod portion 224 connecting the locking 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. The diameter of the 222 and 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 and the 8 200912153 rod portion 224 of the lock member 22, respectively, 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 is inserted 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 226. 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 200912153 (four) is: the hole diameter of the mounting hole 282 is preferably smaller than the outside of the flange 246': so that the f-edge 246 can be fitted into the mounting hole 282 in a riveted manner: the pick-up sleeve 24 and the component The bond between 28. During the above-mentioned locking and fixing process, 'since the lock of the lock member 22=turns through the limit portion 244彳4 of the branch cylinder 24, it can be limited to &#% blocking and not directly detached from the support sleeve 24, that is, the lock The engaging portion is, for example, reversely rotating and forming a threaded engagement with the limiting portion 244 to be able to exit the retaining portion 244. If the locking portion 222 is only in the opposite direction, it does not reversely rotate into the limiting portion 244. To achieve the threaded engagement, the external thread on the portion 222 is blocked by the restriction portion 244, i_古奸··············································· During the process of the shackle, the lock member 22 can be prevented from being detached from the fulcrum sleeve 24 to ensure the smooth progress of the lock-and-fix process. When two or more components are removed, the detached lock 222 is detached. It can still be kept outside the branch sleeve: the loss of the lock-free member 22 makes it difficult to reassemble. The F-mounting device 2 can be fixed to the component 28, so that it is locked. It is not easy to fall off and lose 'to avoid assembly:: It is difficult. Further 'Because the locking device 20 is provided with elastic members 26, it can be 26 pieces by (4) pieces The locking locks 2 sag the third hole section 6' of the protruding branch sleeve before locking the two or more components to facilitate the locking process. It can be understood, for example, that the locking portion 222 is configured. The above-mentioned locking device of the bit portion may have other structural changes, and may be other structures other than the stud, for example, the hook or the slot 244 may be provided with other structures, for example, the hole 1212153 is formed with a tortuous path. The locking portion 222 needs to perform a curved motion to pass therethrough; or an elastic barb is formed on the wall of the hole, and the locking portion 222 of the locking member U is passed therethrough by pushing; or a rib is formed on the wall of the hole, The retaining portion 244 is expanded by the heating support sleeve 24 to pass the locking portion 222; or the locking portion 222 is first passed through the limiting portion 244, and then the bump portion 2 is stamped to form a bump to limit The locking portion 222 is withdrawn. In addition, it can be understood that the elastic member 26 in the locking device 20 can be omitted; even any two of the first hole segment 2, 422, the second hole segment 2424 and the third hole segment M26 are omitted. In summary, the present invention complies with the requirements of the invention patent, and is 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 embodiments, and those skilled in the art will be equivalently modified according to the spirit of the invention.
