An end part of the cover 3 forms a hooking member 301 and a pivoting member 302. The cover 3 has a base portion 31 and the extension part of the base portion is bended to form a bent portion 32. The aforementioned hooking member 301 and the pivoting member 302 are formed by the extension of the end part of the base portion 31. In addition, the inner wall of the cover 3 forms at least one slot 33. The slot 33 could be formed by the extension of the inner wall of the base portion 31 and side wall film 32.
The support frame 4 could be a strip-like shape and length of the support frame 4 is approximate or equal to length of the frame body 2. The number of the support frame 4 could also be two or three above. The current invention takes three as the example. The support frame could form the setting slot 41.
The quantity of the attraction button 5 corresponds to the quantity of the aforementioned support frame 4. Each attraction button 5 has an attracting component 51 and an attracted component 52. The number of the attracting component 51 and the attracted component 52 are installed according to the requirement.
The attracting component 51 could be a magnet which has magnetism and the attracted component 52 could be a piece of iron which has permeability. Thus, the attracting component 51 is able to attract the attracted component 52. Moreover, the attracted component 52 could also be a magnetic so that the two components could attract each other while the two of the magnetic pole are opposite. The attracting component 51 and the attracted component 52 of the attraction button 5 are installed at corresponding position on the support frame 4 and the cover 3, in which the attracting component 51 could be installed on the support frame 4, and the attracted component 52 is installed on inside of the cover 3.

Then, the nut H screws with the prominent part P of the screw S together to support the combination end part 42. Therefore, the combination of the fixing track 21 and the combination end part 42 of the support frame 4 could be created and further secure the support frame 4 on the frame body 2.
The cover 3 would be able to combine to the frame body 2 due to opening and closing. The end part of the cover 3 having hooking member 301 and pivoting member 302 is corresponding to the receiving space 6 on the frame body 2. The end part is able to go into and get out from the receiving space 6 while taking opening and closing actions. As shown in Fig.4, while the cover 3 is at the closing position, the hooking member 301 is away from the engaging member 61 of the receiving space 6 of the frame body 2 and the pivoting member 302 catches the fulcrum member 62 to prevent the cover 3 from loosing out the frame body 2. Meanwhile, the attracting component 51 of the attraction 5 would be able to attract the attracted component 52 for locking the cover 3 at the closing position.
As shown in the Fig.5 to Fig.7, while the cover 3 is gradually lifted, the attracting component 51 and attracted component 52 would be gradually separated. The hooking member 301 would also gradually go into the receiving space 6 at the same time. When the cover 3 reaches certain position, the engaging member 61 in the receiving space 6 would stock the hooking member 301 of the cover 3 for locking the cover 3 at certain position. In current embodiment, since protrusion 611 of the engaging member 61 stocks the hooking member 301 and uses the touching point of the fulcrum member 62 and the base portion 31 of the cover 3 as a fulcrum so that the cover 3 could be locked at certain position.
In addition, in current embodiment, the receiving space 6 on the frame body 2 is formed by an end part of the frame body and part of the end part 42 of the support frame 4. The aforementioned engaging member 61 is formed by the extension of the frame body. The fulcrum member 62 locates on the wall of the receiving space 6 formed from the support frame 4 which has advantages of saving the cost of the frame body 2.
As shown in Fig.8, in another better embodiment, while the cover 3 reaches certain position, the engaging member 61' in the receiving space 6, a projection 611' of the wall of the receiving space 6, would stock the hooking member 301 of the cover 3 for locking the cover 3 at certain position. In current embodiment, since projection 611' of the engaging member 61' stocks the hooking member 301 and uses the contacting point of the fulcrum member 62 and the base portion 31 of the cover 3 as a fulcrum, so that the cover 3 could be locked at certain position.
The design of the aforementioned receiving space 6, in another better embodiment as shown in the Fig.9 and Fig.10, the receiving space 6' is formed by the extension of an end part of the frame body 2.
