[0021] like Figure 2 and Figure 4 As shown, the entry frame 5 is provided with a rectangular notch 7 at the vertical surface inside the bottom plate 4, a rectangular rod 8 is provided inside the bottom plate 4, and one end of the rectangular rod 8 passes through the bottom plate 4 and extends outward.
[0022] like Figure 4 As shown, a pull rod 9 is provided on the vertical plane of the rectangular rod 8 at the bottom plate 4, a pair of L-shaped positioning rods 10 are provided on the vertical plane of the rectangular rod 8 close to the entry frame 5, and several guide frames 11 on the same horizontal line are provided on the bottom surface inside the bottom plate 4, and the guide frames 11 clamp the rectangular rod 8, and the rectangular rod 8 and the guide frames 11 are not in a fixed relationship.
[0023] like Figure 4 and Figure 5As shown, a round rod 12 is provided at the vertical surface of the L-shaped positioning rod 10 close to the entry frame 5, and the diameter of the round rod 12 corresponds to the hole set on the fixing member 6, a rectangular sheet 13 is provided at the vertical surface of the rectangular rod 8 away from the pull rod 9, and a pair of symmetrical baffles 14 are also provided on the bottom surface of the bottom plate 4, a guide rod 15 is provided at the vertical surface of the rectangular sheet 13 facing the baffle 14, and the guide rod 15 penetrates the baffle 14, and the guide rod 15 and the baffle 14 are in a sliding relationship, and a memory spring 16 is provided on the rod body of the guide rod 15 between the baffle 14 and the rectangular sheet 13.
[0024] like Figure 1 , Figure 2 and Figure 6 As shown, a limit plate 17 is provided on the upper surface of the chassis shell 1, and an L-shaped notch 18 is penetrated through the vertical surface of the limit plate 17, and a protrusion 19 is penetrated through the long vertical surface of the L-shaped notch 18, and there is a sliding relationship between the protrusion 19 and the limit plate 17.
[0025] like Figure 1 , Figure 2 and Figure 6 As shown, a rotating rod 20 is provided at the vertical surface of the rectangular plate 2, and the rotating rod 20 and the rectangular plate 2 are in a rotational connection relationship, a rectangular block 21 is penetrated by the rod body of the rotating rod 20, the rotating rod 20 and the rectangular block 21 are in a fixed relationship, and a limiting groove 22 is also provided at the vertical surface of the rectangular plate 2, a limiting rod 23 is provided at the circular surface of the rotating rod 20, and the end of the limiting rod 23 away from the rotating rod 20 is in the limiting groove 22, and a fixing bar 24 is provided at the vertical surface of the rectangular block 21 close to the limiting plate 17.

Since a pair of fixing parts 6 are provided on the lower surface of the rectangular plate 2, and holes are provided on the fixing parts 6, and the diameter of the round rod 12 corresponds to the holes provided on the fixing parts 6, when the rectangular rod 8 is pulled, the round rod 12 will be disengaged from the fixing parts 6, and then the vertical rectangular plate 2 can be gradually changed to a horizontal state through the handle 3. As the rectangular plate 2 continues to become horizontal, the fixing bar 24 will first contact the protrusion 19 through the L-shaped notch 18, and then the pressure generated by the flattening of the rectangular plate 2 will push the protrusion 19 originally protruding outside back into the inside of the limiting plate 17. Since the protrusion 19 is inside the limiting plate 17, a spring is provided. Therefore, when the fixing bar 245 is at the bottom of the L-shaped notch 18, there is no restriction of the obstacle at this time, and the protrusion 19 will rebound under the action of the spring, thereby jamming the fixing bar 24.
