It can be understood that the pin 1〇1 can also be replaced by another card fastener which is fixed to the main shaft and accommodated in the spiral groove 23, so that the protrusion 20 can be screwed with the main shaft 10. The thickness of the fastening ring 1〇2 corresponds to the width of the neck portion 15 of the main shaft 10, and is engageable in the neck portion 15 and abuts against the reinforcing block of the fixing base 7 to prevent the fixing seat 70 from being along the main axis. 10 slides. Further, the deformed through hole 76 of the fixed seat cooperates with the deformed end portion 14 of the main shaft 1G to restrict the rotation of the fixed seat relative to the main shaft 10, so that the fixed seat 7 is relatively fixed to the main shaft ι. Please refer to Fig. 5 at the same time. When assembling, insert the large diameter portion u of the main shaft 1 into the cam 20. Insert the pin 101 into the space formed by the two spiral grooves 23 13 200819649 of the cam 2 and the pin holes 13 of the main shaft 10. In the space, the cam 20 is connected to the main shaft 1 (the helix is spirally connected. The small diameter portion 12 of the main shaft 10 is sequentially passed through the follower 30, the sleeve 40, the return spring 50, the compression spring 51, the switching member 60, and the fixing seat 70. And the fastening ring 102 is clamped on the neck 15 of the main shaft 10. The cam surface 21 of the cam 20 cooperates with the cam surface 31 of the follower 30, and the convex peak 212 of the cam surface 21 is located at the valley 311 of the cam surface 31. The sliding rod 42 of the sleeve 40 cooperates with the sliding groove 33 of the follower 30. The curved arm 61 of the switching member 60 cooperates with the curved groove 43 of the sleeve 40. The stopper 62 of the switching member 60 is received in the fixing seat The end of the retaining groove 74 abuts against the side wall 741 of the retaining groove 74. The first end of the return spring 50 abuts the semi-closed end 41 of the sleeve 40, and the second end abuts against the switching member 60 The retaining spring 50 has a certain pre-pressure. The first end of the compression spring 51 abuts against the plane 32 of the follower 30, and the second end thereof abuts against the partition 75 of the fixed seat 70. The compression spring 51 has a large pre-pressure. The deformation through hole 76 of the fixing base 70 cooperates with the deformed end portion 14 of the main shaft 10, and the snap ring 102 abuts against the reinforcing block 77 of the fixing base 70. The pressing arm 83 of the button 80 Passing through the pressing hole 78 of the fixing base 70 and abutting against the abutting arm 63 of the switching member 60. The holding piece 91 of the holding member 90 passes through the pressing portion 81 of the button 80 to abut the flange 82 of the button 80, and The hook hole 93 of the holding member 90 is engaged with the hook 73 of the fixing base 70. The hinge structure 100 is integrated. The fixing portion 71 of the fixing base 70 is connected to the body 202 of the mobile phone 200, and the protrusion 22 of the cam 20 is The cover 204 of the mobile phone 200 is connected, that is, the installation is completed. In the initial state, the cover 204 is relatively closed with the body 202, and the compression spring 51 has a large pre-pressure, acting on the follower 30 14 200819649 and It is transmitted to the cam 20, so that the cam 2〇 has a tendency to move along the main shaft 1〇 away from the follower 3〇. At the same time, due to the cooperation of the pin with the cam 2〇 and the green shaft 10, the cam 2〇 has a relative The tendency of the spindle to rotate. Another 'Because the pre-pressure of the compression spring 51 pushes the follower 3〇, The follower 30 is closely engaged with the cam 2〇, so that the follower 3〇 has a tendency to rotate together with the cam. The stepwise, the follower %, the sleeve buckle and the switching: 60 the sliding fit makes the The three can only slide relative to each other and thus the sleeve 40 and the switching member 60 have a tendency to rotate. However, since the switching member 60 is locked to the fixing seat 7β, it cannot be combined with the sleeve 4, the follower and the cam 20. When the cam and the main # are required to open the cover 2〇4 of the mobile phone 2, the button (10) :: pressing portion 81 is pressed. The button 8 is pressed by the pressing arm 83 to push the switching member 6 to abutment = 3. The switching member 6 〇 resists the pre-pressure of the resetting elastic 〇 5 ,, and moves toward the sleeve 仙: The return spring 50 is dusted and has a compressive force. Switching member: The member is withdrawn from the retaining groove 74 of the fixing base 7〇, and the cutting member is unlocked with the fixing base 7G. - The pressure spring Μ releases the pre-pressure. The pre-house force acts on the follower 3〇 and is transmitted to the cam plus. The cam 20 spindle 10 is away from the follower % direction _ 101 with the cam 20 and the spindle 10 The match is due to the pin rotating for the spindle U). At the same time, since the secret ^2() moves the phase member 30 at the same time, the reset magazine 5箬; ^ the pre-M force pushes the driven slave to drive the follower 3〇:, 4='= the page sleeve 4〇, thus The cam is twisted and the knife changer 60 is rotated, and the follower % 艟 second " a spindle ι 移动 moves toward the cam 2 。. When the cam 20 is rotated-angled, the pin 1〇1 is rotated from one end of the spiral groove 23 to the second (four) 15 200819649. The return spring 50 releases the pressure, and the push switch 60 is slid into the fixed seat 70, and the switching member 60 is The stopper 62 is received in the stopper groove 74 of the fixing seat 70 and abuts against the other side wall 742 of the stopper groove 74 to be relocked. The body 204 is fully automatically popped relative to the body 202. When the cover 204 of the mobile phone 200 is closed, an external force acts on the cover 204, and the cover 204 drives the cam 2 to rotate. The cam 2 is moved in the direction of the follower 30 along the main shaft 1 〇 while rotating. Since the switching member 60 is restrained in the holder 7〇, the follower 3〇, the sleeve 4〇, and the switching member (10) cannot be rotated by the spindle 1〇. The cam 20 pushes the follower 3 and the sleeve 4〇 :::: m51 and the return spring 5 〇 are both compressed to accumulate Lili. After the convex angle of the member 30, the convex peak 212 of the cam 2 turns over the driven stop force, and the follower 30 automatically slides into the concave of the cam 20 under the action of the compression spring 51, and the main shaft 10 is the same. The 211 sub-moving cam 2 〇 continues to re-lock with respect to the block 62 abutting against the stop back to the home position ‘and the cover 14 wall 741 of the switching member 6〇. The mobile phone body 204 is closed relative to the body 202. The driven sleeve 4〇 can be omitted and the switching member 60 is directly placed C=f. The switching member 6 is provided with a control portion, and the follower is provided with: the member 30 is slid and cannot be rotated s / the more knife changing member 60 is only relatively movable and the switching member 60. It can be understood that the sleeve 5 can directly abut the follower. The sleeve can also be other structures. Only the 30 slide can not be rotated, that is, the slide 42 of the 40 and the slide 33 of the follower 30 can be realized. The cartridge 4 can only be relatively movable. Similarly, the arcuate arms 61 of the switching member 60 and the arcuate slots 43 of the 16200819649: odd 40 may be other structures as long as the energy member 60 can only slide relative to the sleeve 4 () and cannot rotate. Real-time switching It can be understood that the 'switching member 6〇 and the fixed seat 曰' can be other structures as long as the switching members 6〇 and : are now locked and unlocked. It is understandable that the diameter of the large diameter portion of the main shaft 1 is the same as the diameter of the diameter portion 12. , J, in summary, the present invention is in line with the requirements of the invention patent, and is proposed in accordance with the law.
