After the rotation of the lead screw 40 is driven, linear expansion and contraction with respect to the outer tube 60 is performed. The linear actuator of the present invention further includes a rear support mechanism 65 (shown in FIG. 5), which mainly includes two half covers 651 and a ball bearing 652 which is clamped and fixed by the two half covers 651. The bearing 652 is provided for the end of the lead screw 40 to be pierced; thus, the actuation stability of the lead screw 40 and the telescopic tube 50 can be further improved. Further, a slot 653 is formed at the joint of the second half cover 651. Referring to Figures 6 and 7, the linear actuator of the present invention further includes a reduction transmission mechanism 70 that is sleeved between the lead screw 40 and between the rear support mechanism 65 and the worm gear assembly 30. The transmission mechanism 70 mainly includes a driven wheel 71, a claw ring 72, a passive bushing 73, a plurality of needle rollers 74, an intermediate ring 75, a torsion spring 76 and a limit stop cover 77. The driven wheel 71 is sleeved at The circular shaft segment 42 of the lead screw 40 is located, and has a plurality of external teeth 711 which are partially connected to the internal teeth 315 of the worm wheel 31. The claw ring 72 is provided with a plurality of card slots 721 which are mutually engaged with the external teeth 711. The claw ring 72 is formed with a plurality of claw arms 722, and a spacing groove 723 is formed between any two adjacent claw arms 722. The passive bushing 73 is provided with an inner positioning plane 731, and a plurality of ribs 732 extend from the outer periphery of the passive bushing 73. A recess 733 is formed between any two adjacent ribs 732, and the passive bushing 73 is sleeved at The lead screw 40 is rotated by the inner positioning plane 731 and the outer positioning plane 421 of the circular shaft section 42, and the passive sleeve 73 is received in each claw arm 722 of the claw ring 72; The needles 74 are respectively inserted into the spaces formed by the respective spacing grooves 723 and the recesses 733 in the form number A0101. The intermediate ring 75 is sleeved on the outer periphery of the claw ring 72 and is in contact with each of the needle rollers 74. The torsion spring 76 is bent with a positioning section 761. The torsion spring 76 elastically tightens the outer periphery of the intermediate ring 75, and the positioning section 761 is inserted into the slot 653 to be fixed. The limit stop cover 7 is sleeved on one side of the passive bushing 73 and encloses the end face of the claw ring 72 and each of the needle rollers (as shown in Fig. 9). As shown in Figures 8 and 9, the linear actuator of the present invention further includes a casing 80 which is wrapped around the drive mechanism 1 and the reduction transmission mechanism 7 and supported by the rear support mechanism 65. The side of the outer tube 60 is placed in abutment. In addition, the linear actuator of the present invention is shown in the first figure. The motor 12 is disposed on one side of the outer casing. Please refer to the eighth figure. When used, the wheel 31 is subjected to the worm: 20 When rotating in the positive direction (4) in the clockwise direction, that is, the lead screw 4〇 drives the telescopic tube 5〇 to retract inside the outer tube 60; please refer to the 归 归 ^ arm 722 to push the intermediate %75 and each needle roller 74 is rotated, by twisting; the direction of rotation of the spring 76 is the same as the direction of rotation of the worm wheel 31, and its positioning section 761 is fixed in the slot 653 of the half cover 65丨 (as shown in FIG. 5), and the torsion spring 76 is provided. The jamming of the intermediate ring π is tight (that is, the intermediate ring 75 is tightly held and cannot rotate), so that the frictional force of each of the claw arms 722 driving the respective needles 74 and the intermediate ring 75 is increased, and the lead screw 40 is lowered. The rotational speed; thus, when the linear actuator is mounted on the electric bed or the chair, the speed of the telescopic tube 50 retracting into the outer tube 6〇 is slower to increase the user's comfort. When the worm wheel 31 is reversely driven by the worm 20 to rotate counterclockwise, that is, the lead screw 40 drives the telescopic tube 50 to extend outwardly from the outer tube 6 ;; continuation form number A010I Page 8 of 24, M404297 Referring to the seventh figure, each of the claw arms 722 will push the intermediate ring 75 and the respective needle rollers 74 to rotate. Since the rotation direction of the torsion spring 76 is opposite to the rotation direction of the exhaust wheel 31, the torsion spring 76 will be loose due to the rotation of the intermediate ring 75. In the open state, the frictional damping between the intermediate ring 75, the torsion spring 76 and each of the needle rollers 74 is small, and the intermediate ring 75 can be easily rotated inside the torsion spring 76; thus, the transmission performance of the internal mechanism can be improved. In summary, the high-load linear actuator of this creation can achieve the intended purpose of use, and solve the lack of conventional knowledge, and because of its novelty and progress, it fully meets the requirements of new patent applications, and is proposed according to the patent law. To apply, please check and grant the patent in this case to protect the rights of the creator.
