With the rotation of the driving screw 30 , a linear displacement is generated in the movable slot 11 , so that the movable opening part 41 can generate an opening and closing action relative to the fixed opening part 13 . Wherein, the through groove 131 allows the movable spread part 41 of the spreader 40 to be accommodated therein, and when the movable spread part 41 is located in the through groove 131, the fixed spread part 13 and the movable spread part 41 are in a state of alignment , this time is the closed position of the fixed spreader 13 and the movable spreader 41, so that the fixed spreader 13 and the movable spreader 41 stretch into the slot 2 of the elevation structure 1 in order to facilitate the creation; 4. When the driving screw 30 is driven and rotated, the expansion part 40 can be linearly displaced in the direction of the driving part 32, so that the fixed expansion part 13 and the movable expansion part 41 are gradually staggered, so that the fixed expansion part 13 and the movable expansion part 41 is located at the open position, thereby achieving the purpose of expanding the slot 2.

In this creative embodiment, the seat body 10 is provided with a limiting member 50 away from the through groove 131 to prevent the expansion member 40 from detaching from the seat body 10 along the rotation axis L. As shown in FIG. Wherein, the limiting member 50 is a spring pin, which is transversely penetrated through the through hole 15 of the base body 10 and fixed on the base body 10 .

As shown in Figure 4 and Figure 5, it is a schematic diagram of the use status of this creation. Wherein, as shown in Figure 4, before the dismounting operation, first make the fixed stretching part 13 and the movable stretching part 41 be in the closed position, so that the fixed stretching part 13 and the movable stretching part 41 stretch into the elevation angle structure 1. in slot 2.

Next, as shown in Figures 1 and 5, the user connects the hand tool 4 to the driving part 32 of the driving screw 30, and rotates and applies force to drive the linear displacement of the expansion part 40, so that the movable expansion part 41 is relatively fixed. The stretching parts 13 are staggered to achieve the effect of stretching the slots 2 of the elevation angle structure 1 .

Due to the relationship between the bearing 20 provided between the seat body 10 and the drive screw 30 of this invention, when the user drives the drive screw 30, the frictional resistance between the drive screw 30 and the seat 10 can be reduced, so that the user can use light force Drive and rotate the driving screw 30 to achieve convenience in use and labor-saving effect.
