The base 11 is slidably connected to the inside of the fixed seat 1. The top of the base 11 is connected to a connecting seat 12, and a detection device 13 is installed on the top of the connecting seat 12. Slide plates 14 are installed on both sides of the outside of the base 11. Slide grooves 15 are opened on both sides of the inside of the fixed seat 1. The slide plate 14 is located inside the slide groove 15 and is a sliding connection structure. Several groups of thread grooves 16 are opened on the top of the base 11. Bolts 17 are commonly connected between the connecting seat 12 and the base 11. The connecting seat 12 and the base 11 are connected by bolts 17. The bolts 17 are adapted to the thread grooves 16, and a butterfly handle 18 is installed on the top of the bolt 17.

[0030] The motor 2 rotates forward for a certain period of time and then rotates in the opposite direction (it can be set by programming, which is a known technology and will not be described in detail here). When the motor 2 drives the active gear 3 to rotate, the active gear 3 drives the driven gear 5 to rotate, and the driven gear 5 drives the screw rod 4 located inside the fixed seat 1 to rotate. When the screw rod 4 rotates, the two movable seats 6 are simultaneously located inside the fixed seat 1 and move toward the middle or to both ends. The connecting frame 9 is a rotating connection structure with the movable seat 6 and the mounting seat 10 respectively. The two movable seats 6 are located inside the fixed seat 1 and move linearly through the arrangement of the connecting plate 7 and the connecting groove 8; the base 11 is slidably connected to the inside of the fixed seat 1 through the arrangement of the slide plate 14 and the slide groove 15; the butterfly handle 18 is arranged to facilitate the user to rotate the bolt 17.
