Description of the Invention: [Technical Field] The present invention relates to a projection screen mechanism, and more particularly to a portable projection screen mechanism. [Prior Art] Please refer to FIG. 1, which is a perspective view of a conventional portable projection screen mechanism. The conventional portable projection screen mechanism 100 includes a base 110, a transverse rod 120, a support rod (SUpp〇rt r〇d) 130, and an automatic rolling device ( Not shown) and a projection screen 140. The automatic retracting device is disposed in the base 110. One side of the projection screen 14 is connected to the automatic retracting device, and the other side of the projection screen 140 is connected to the cross bar 120. When the portable projection screen mechanism 100 is in use, one end of the support bar 13〇 is inserted into the base 110, and the other end of the support bar 130 is fixed to the cross bar 120 such that the support bar 130 supports the cross bar 12〇. At this time, the projection screen 14 is pulled out, and the automatic retracting mechanism applies a winding torque to the projection screen 14A. When the portable projection screen mechanism 100 is in an unused state, the support rod 130 is detached from the base 110 and the crossbar 12〇, and the torsion force applied by the automatic retracting mechanism winds the projection screen 140 in the base 11〇. The support bar 130 is a detachable member, so the user must carry the stand bar 130 and the base 11 to use the portable projection screen mechanism (10) at any time. Therefore, for the user, the portability of the portable projection screen mechanism is less convenient. In addition, when the portable projection screen mechanism 1QQ is in use, only one of the tower poles 130 is supported, so the projection screen 140 The invention will provide a projection screen mechanism which is convenient for the user to carry. Other objects and advantages of the present invention will become apparent from the teachings of the present invention. The present invention is directed to a support device (supp〇rtdevice), (), a retracting device and a projection screen. Lathe (latehdevice), ο rods. The snap device includes at least - a pure elastic member. A latch element of the card and one end of at least one of the latch members are attached to one of the sliders. Elasticity ^ should be >, block and snap fasteners. The retracting device is configured to be connected to the automatic retracting device, and the other side of the projection screen is connected to the side of the screen; when the projection screen is purely surrounded by the retracting device, the rod member is adjacent to the supporting rod and the elastic member The elastic deformation causes the phase of the fastener and the one end of the first end to buckle one of the support poles to unfold the projection screen, and the retracting mechanism applies a winding torque to the projection screen. 〇 In the embodiment of the invention, the elastic member is a compression elastic piece. In an embodiment of the invention, the retracting device comprises a rotational shaft and a torsion spring. The rotating shaft is disposed on the base and adapted to rotate about the axis. Twist # is set on the rotating shaft. Twisted: the first end is fixed to the rotating shaft, and a second end of the torsion spring opposite to the first end is fixed to the base. When the projection screen is taken up, the projection screen surrounds the rotating shaft. When the projection screen is unfolded, the torsion spring is elastically deformed to apply a winding torque to the projection screen. / In an embodiment of the invention, the retracting device further comprises a connection dement, a reel, and a rotational tube. The connector is fixed to the base. One end of the rotating shaft is rotatably coupled to the connecting member, and the second end of the torsion spring is fixed to the connecting member. Runner sleeve 5 201035669 Twist: two = turn two other - end. The rotating screen is sleeved on the rotating shaft and retracted, and the projection screen is connected to the rotating tubular member around the side. When the projection screen is in an embodiment of the present invention, the at least one fastening component, the second elastic member has two, the first end of the fastening component is on the block, and the miscellaneous components are connected to the opposite slider. Fasteners.曰Because the implementation of this embodiment, the curtain mechanism is equipped with (4) these support rods on the base, so it is less portable than the conventional technology.
