Description of the Invention: [Technical Field] The present invention relates to a transmission device, in particular to a telescopic actuator [Prior Art] The use of an actuator is extensive, mainly due to its internal motor drive Self-retracting and driving other mechanisms to act, currently the technology of the _, as shown in the US patent, the number shown in the curry 16, is a motor and three screw in a three-section telescopic sleeve The three screws are respectively connected to the sleeves of the telescopic cylinder, and the third screw is driven by the motor to be axially displaced, so that the telescopic sleeve can be driven to expand and contract; d. The activist as shown in European Patent Application No. EPG9_8 is provided in a three-section telescopic sleeve - a motor, a screw and a pulley that drives the screw to rotate, the screw driving a sleeve provided with the pulley The displacement of the cylinder, which in turn drives the displacement of the other sleeve by means of a moving pulley, thereby driving the telescopic sleeve to expand and contract; the conventional actuator of the previous method must use a screw to drive the telescopic sleeve to expand and contract. There is rarely a driving method of this kind, and the present invention is more motivated to 'develop a telescopic actuation directly driven by a telescopic member. 200916673 [Explanation] The purpose of the present invention is to provide a telescopic expansion and contraction using a telescopic cylinder Actuator. (4) In order to achieve the purpose of the disclosure, the telescopic actuator comprises a "retractable sleeve, a motor and a telescopic member", wherein the telescopic sleeve is composed of a plurality of sleeves from the outward direction: the sleeve is formed in a sequence of 'the motor and the telescopic member (4) being placed in the telescopic sleeve =, and the horse is set at the telescopic (four) end, the telescopic member is made up of a complex body, and the frame member is formed into a 'X-shaped frame' The pivot members are hung in the same direction, and the pivot members are respectively pivoted with two adjacent end portions of the rod body and two adjacent end portions of the rod body of the adjacent pivot member, and the telescopic member is further The sleeves are connected, and the two end portions of the telescopic member-end are driven by the motor to approach or move away from each other in the opposite direction, thereby controlling the elongation or shortening of the telescopic member, and interlocking the telescopic sleeve for expansion and contraction; The motor drives the end portions of the end of the telescopic member: the movement can move the telescopic member to expand and contract, and at the same time, the telescopic sleeve is interlocked for expansion and contraction. In addition, the motor drives the expansion and contraction structure of the telescopic member, so that the horse 200916673 pulley rotates 'the pulley drives the two teeth and two ports respectively with two belts', wherein the gear and the sliding sleeve are disposed in the telescopic sleeve The other gear (four)-the steering gear is combined with the other tooth that is slidably disposed on the protruding member, and the two racks are respectively connected with the telescopic end portion to enable the two __ pulleys to rotate when the pulley is rotated The ends are close to or away from each other in opposite directions. [Embodiment] The telescopic actuator of the present invention shown in Fig. 4 is embodied, for example, in the first embodiment, and includes: a telescopic sleeve 1G, which is sleeved from the outside by three sleeves h, 12, and 13 The outermost sleeve 11 has a slide (1), and the slide 111 extends in a direction perpendicular to the sleeve direction of the three sleeves 11, 12, 13, and two gears are disposed in the sleeve 11. 112, 113, a steering gear 114 and two racks 115, 116, the two gears ΐ 2, rotatably pivoted in the (four) W, and: the wire ΐ 2, the coaxial coaxial connection - pulleys 112A, 113A, the steering gear The ΐ4 is rotatably disposed in the sleeve n and is coupled to the gear ii3. The two racks 115 and 116 are respectively slidably disposed on the slide ill and respectively sprayed with the gear 112 and the steering gear 114. The sleeve 13 of the inner layer is provided with an elongated strip of perforations 13 and the direction of extension of the perforations 131 is also perpendicular to the direction of the sleeves of the three 200916673 sleeves π, 12, 13; a motor 20' is fixed to the telescopic sleeve a pulley 9 is assembled on the outermost sleeve u and the motor 20 has its pulley (not shown), the belt 21 along the axis of rotation thereof is adjacent to the two belts eight A2, the belts A1, A2 are respectively wound around the two pulleys 112A, 113A in the outer sleeve 11 of the telescopic sleeve 1; And a telescopic member 30 disposed in the telescopic sleeve 10 and connected to the two sleeves 11, 12, 13, respectively, the telescopic member 30 is composed of a plurality of rods 31, each of which is in the middle A pivot node 311 is pivotally connected to an X-shaped pivot member 32. The pivot members 32 are pivotally connected in the same direction, and the pivot members 32 respectively have two adjacent end portions 312 of the rod body 31 and adjacent frame members. Two adjacent end portions 312 of the rod body 31 of the 32 are pivotally connected, and the two end portions 312A, 312B of the telescopic member 3 and the telescopic sleeve 1 respectively engage the two racks 115, 116 in the outermost sleeve 11 thereof. The first end portions 312C and 312D of the telescopic member 3 are respectively inserted into the through holes 131 of the sleeve 13 by a shaft Βΐ and β2, and are connected to the sleeve 13. Further, the extension member 30 is coupled to the sleeve 13 A pivoting member 32 of the sleeve 12 is fixedly connected to the sleeve 2 by a pivot node 311 thereof with a shaft B3. When the Ge Hai motor 20 is in operation, the pulley 21 is driven to rotate and the two belts A1 and A2 are actuated. The two belts A1 and A2 are linked to the two skins 200916673 to read 112A and 113A to rotate 'in the two gears 112 and 113. When the two-spin π wheels 112A, 113A rotate synchronously, the gear 112 will mesh with the rack 115 to drive the rack 115 to slide on the slide (1). "The gear 113 will be linked through the steering gear 114. The rack 116 is slidably displaced on the β-channel 111. Since the two belts are driven in the same direction, the two pulleys 112Α, 113Α and the two gears 112 and 113 are also operated in the same direction, but the gear 112 is directly and The rack 115 is engaged, and the w-wheel 113 is in contact with the rack through the steering gear 114, so that the rack 115 and the rack 116 are opposite to each other;
