The convex blocking piece 33 can cooperate with the arc-shaped end piece 273 as a limiting device for the relative rotational stroke; at the same time, the main shaft of the frame shaft 31 is also provided with a flattened portion 34 which is cut plane 272 with respect to the hollow shaft tube 27. The transmission shaft 40 can pass through the pivot shaft 31 assembled in the hollow shaft tube 27 opposite to the central hole 32 for engaging and interlocking the internal preset power transmission mechanism of the sliding seat (1), and transmitting power to the transmission shaft. 40 The opposite end of the hidden cover slide structure for synchronizing the upper cover sliding translation and the upper jaw movement. • At the same time, the above-mentioned boring shaft 3 插 is inserted into the opposite side hole 110 (refer to Figs. 2 and 8) in parallel with the flat shaft portion 35 to synchronously drive the carriage 1 〇. The sliding seat 10 defines a first recess U for assembling the power transmission mechanism. In a feasible embodiment, the power transmission mechanism includes at least a first gear 12 and a first gear 1.3 ′ which are toothed to each other. The first gear 12 is inserted into and connected to the end of the transmission shaft 40 via a side wall.

A second recess 14 is provided in the rear of the slide base 10 for the assembly-positioning wheel 15 therein. In the illustrated embodiment, the positioning wheel 15 is movably mounted on a shaft 16, and the support shaft is The matching flange 161 is positioned on the surface of the slider 1 相对 relative to the recess 1 〇 4 and the socket 1 〇 5 (refer to the second, * and $ figures). As shown in Fig. 2, the '-link piece 17 is disposed on the inner side of the slider 1〇, so that the link piece 17-end is connected to one end of the torsion device shaft, and the link piece π The other end is activating the preset outrigger 18 of the upper scale 1G_. 7 As shown in Figures 2, 4 and 5, the above-mentioned bracket 5〇 can be locked and shielded by the bolts 51, 52 to the upper surface of the sliding seat 10 with respect to the inner screw hole. The local rim of the positioning wheel 15 is exposed by the slot 53; the entire clamping frame has two preset clamping slots on both sides of the upper surface for assembling the sliding sleeves 54 and 55 of the opposite cross-sectional shapes; the rail 6〇 can be positioned on the sliding cover The upper cover 90' of the electronic device is slidably assembled between the sliding sleeves 54 and 5%, and the rack 56 is locked under the rail 60, and the middle portion of the rack 56 is in a normal state. The teeth are connected to the second gear 13 described above. The above-mentioned rails 6() are respectively provided with positioning notches 61 at the positions of the front and rear rims of the positioning wheel 15 (see Fig. 2). As shown in Fig. 4, when the present invention is applied to a slide type electronic device, the upper cover 9 can be slid to the right by the unused closed state in the closed normal state, so that the entire upper cover 9g is gradually removed from the lower body 80. Outside (as shown in Fig. 6), during the sliding translation process, the rack 56 and the second gear 13 are interlocked, so that the first gear 12 rotates and drives the transmission shaft 4〇, and the interlocking group is disposed on the transmission shaft 4〇. The other side of the other side of the slide cover structure. On the slide-type electronic device, cover yu _ to the end of the 6th _ stroke and then open up as shown by the arrow in Figure 7. Please also refer to Figure 8~10, as described above for the preset tenon The piece % can be matched with the arc type end piece as the upper cover 9〇 maximum opening stroke: the restriction device (10) H) is shown in the figure); at the same time, in the process of sliding money with the upper (four) picking up (four) step axis 姊 31 miscellaneous, making the county missing 2 Turning the corners on the (four) face - ^ eyes on the cut ^ forced Zhang 'the shape of the ship's force to position the fan on the set of the shaft ^ when the secret 'the above-mentioned link piece 17 - the end will be preset with the above torque device side The other end of the 18 H miscellaneous... The 17th threat will rise on the other side of the seat 10 as the upper part of the slide 1G rises, and the entire link piece π becomes the oblique support state (see 7 and 8). Fig.), with the torsion device at one end and the inner step portion 23 of the side fold m, the pressing force of the stroke zone of the same thickness of the same thickness is applied to the upper cover of the slider electronic device. The n-th is a schematic diagram of the sliding electronic device, and the cover structure is arranged in a set in a manner of a sliding electronic device composed of the body (10) and the upper cover. Inside the side edge, the squat upper sill structure can be transmitted via the drive pump 40 to the slide cover upper structure on the other side. Since the drive shaft is located at the same center line as the drag shaft as the stick shaft, except that the drive shaft can be concealed and hidden in the body as the system end, the entire transmission mechanism only needs to make the counter-group relative gear. 'There is no need to effectively turn the structure of this eye-moving electronic device; at the same time, the space of the radius of gyration caused by the transmission of the Lai-center line member can also be secret, which is beneficial to the uncovering type electronic setting _into step _.
