In order for your review board to have a clear understanding of the content of this creation, please refer to the following description only.

Please refer to Figures 1, 2, 3 and 4 to 5 for an exploded perspective view of the preferred embodiment of the present invention, and a cross-sectional view and a top view thereof after assembly, and various state diagrams in use thereof. As shown in the figure, the reciprocating telescopic device 1 of the present invention is used for various devices (not shown) that require reciprocating telescopic power, and the reciprocating telescopic device 1 includes a casing 11 and a fixing. The seat 12, a rotary power source 13 and four telescopic assemblies 14.

The outer casing 11 has a cylindrical shape and has an accommodating space 111 therein. The opening of one end of the outer casing 11 is fixed with a plate 112 to be closed to make the outer casing 11 open on one side.

One end of the fixing base 12 is inserted into the outer casing 11 , and a plurality of bearings 121 are disposed between the outer casing 12 , and a fixing groove 122 is defined in a central portion of the fixing base 12 to make the fixing base 12 The housing 11 can be stably rotated inside, and the outer surface of the fixing base 12 is provided with an arcuate ring groove 123. In addition, the fixing seat 12 is provided with a positioning notch portion 124 corresponding to the shape of the arcuate ring groove 123, so that the positioning notch portion 124 is located below the highest point of the arcuate ring groove 123.

The rotary power source 13 is selected from a common common induction motor, and is covered in the fixing groove 122, and one end of the rotary power source 13 has a rotating shaft 131. Moreover, the central axis of the arcuate ring groove 123 and the central axis of the rotating shaft 131 have a set angle θ.

The four telescopic assemblies 14 are respectively mounted on the surface of the outer casing 11 to connect the devices, which are respectively disposed on four bisectors outside the outer casing 11, and each of the telescopic assemblies 14 includes: a pair The limiting seat 141 is fixed to the outer surface of the outer casing 11 in an adjacent manner, and the pair of limiting seats 141 are respectively provided with a sliding slot 1411 corresponding to the axial direction of the rotating shaft 131, and each of the sliding slots 1411 The shape is in the shape of an I-shape. Therefore, the two sliding grooves 1411 are in a straight line; a rod body 142 has a cross-sectional shape corresponding to the shape of the sliding groove 1411 and also has an I-shape for being inserted into the two limiting seats 141. The embodiment of the pair of sliding slots 1411 forms a limit sliding manner, so that the rod body 142 can reciprocate along the extending direction of the pair of sliding slots 1411, and a pulley 1421 is disposed at one end of the rod body 142. So that the pulley 1421 is located at one end of the outer casing 11 that is not closed, The activity is provided in the arcuate ring groove 123. It should be noted that the set angle θ used in the present invention is between 10 degrees and 45 degrees, and the amount of expansion and contraction of each of the rods 142 can be adjusted through different set angles θ.

Since the telescopic components 14 of the present invention are disposed at four equal points of the outer casing 11, a first actuation zone S1, a second actuation zone S2, a third actuation zone S3, and a first The four actuation zone S4, when the outer casing 11 is driven by the rotary power source 13 for cyclic rotation, the pulley 1421 of each telescopic assembly 14 is limited by the path trajectory of the curved annular groove 123.
