In order to solve this technical problem, a connecting component 2 and an auxiliary component 3 are added on this basis.

[0044] It should be noted that the pull ring 211 is provided to facilitate the operator to rotate the screw rod 210 when the operator needs to rotate it.

[0049] It should be noted that the telescopic module 32 is mainly composed of a cylindrical telescopic rod and a spring, which can lift the positioning plate 13 off the ground for easy pushing.

[0050] The working principle and use process of the utility model are as follows: take out the two positioning plates 13, insert the insert block 21 into the interior of the slot 22, and during the insertion, because the opposite sides of the insert block 21 and the positioning block 25 are both inclined, the positioning block 25 will be lifted up first, until the positioning hole 23 is located below the positioning block 25, the positioning block 25 will be inserted into the interior of the accommodating cavity 26 through the positioning hole 23 due to gravity to limit the two positioning plates 13, place the generator body 1 on the upper surface of the positioning plate 13, slide the pulley 12 inside the slide rail 14 until the end of the slide is reached, remove the rear positioning plate 13 to extend the length of the track, and press the force block 2 downward.
