The specific working process is as follows. When the switch 29 is pressed, the push top 294 of the switch 29 will move downward along the wedge surface 258 and squeeze the two retaining members 25 to slide back there so that the locking pin 274 of the support arm 27 and the recess Unlocked. Under the elastic force of the torsion spring 24, the free end 226 of the support member 22 will eject the receiving hole 1222 of the housing 10, and together drive the guiding groove 272 of the supporting arm 27 to slide along the guide 212 toward the torsion spring 24. . Until the lock pin 274 slides back to the lower groove 256^, the support arm 27 stops sliding even. At this time, the support member 22 and the housing 201116193 10 form a support angle, and the support member 22, the support arm 27 and the housing 10 together form a stable triangle to stabilize the housing 1 by the bracket mechanism 20. Ground support. If it is necessary to open a large angle between the support member 22 and the housing 1〇, it is only necessary to continue to press the switch 29, • the two holding members 25 are separated by a large distance 'so that the locking pin 274 slides in and locks in more The groove 256 of the torsion spring 24 is adjacent. It will be appreciated that the guide post 1224 on the housing 10 cooperates with the sliding slot 252 on the retaining member 25 to permit relative movement of the retaining member 25. Therefore, the guide post 1224 is not limited to being disposed on the casing 10. The same effect can be achieved by arranging the guide post 1224 on the substrate 21. It can be understood that the 'substrate 21 and the bottom wall 122 of the housing 1 are held in the middle by the holding member 25' to maintain the locking pin 274 of the support arm 27 from being disengaged from the holding member 25 and locked in the recess 256 of the holding member 25. . However, in order to achieve the above-mentioned object, a guide groove may be respectively formed on both sides of the guide rail 212 of the substrate 21, and a guide is respectively protruded on the opposite side walls of the guide groove 272 of the support arm 27. The pin is slidably disposed in the guiding groove to ensure that the locking pin 274 does not disengage from the holding member 25 and locks into the groove 256 of the holding member 25. It will be understood that the mounting groove 216 of the substrate 21 cooperates with the recess 1226 of the housing 10 to define a cylindrical mounting cavity ' for mounting the sleeves 2222, 2224 of the support member 22. Therefore, a cover body provided with the recess is mounted on the substrate 21 to form the mounting cavity, and the sleeves 2222, 2224 of the support member 22 can also be rotatably mounted on the substrate 21. One end of the support member 22 of the bracket mechanism 20 of the present invention is rotatably coupled to the housing 1 ,, one end of the support arm 27 is also rotatably coupled to the support member 22' and the other end of the support arm 27 is held thereon. The holding member 25 in the housing 10 is intermediate, so that the support member 22, the support arm 27, and the housing 10 are formed in a stable triangle, so that the 201116193 housing ίο is stably supported. If it is necessary to change the support angle between the contact 22, the switch 2 is only required to be moved away from each other by the switch 29 on the casing 1 , and the free end of the gift n is moved under the elastic force side of the twisting % That is, it is automatically bounced off the casing 1G to form a larger branch between the struts 27 and the casing ι. Therefore, the bracket mechanism 2 () of the present invention is easy to open. = Pressing the switch 29, the other end of the support arm will be held in the middle of the holding member 25. By repeating the above action, different support angles can be formed between the struts 27 and the casing (4) so that the bracket mechanism 2 〇 forms different forces on the casing 1 。. , 本本,明的电子装置 The support of the brain is large and the angle is convenient.
