Detailed ways

As shown in Figures 1 to 8, the present invention mainly includes a first rod 1, a second rod 2, a top plate 3, a connecting plate 31, a first baffle 32, a second baffle 33, a guide tube 34, a spring 35, a latch 4. Positioning plate 43, lug 44, rope 6, rotating shaft 61, handle 62, bearing 63 and bolt 7, the present invention will be described below in conjunction with accompanying drawing.

As shown in Figure 1, the first rod 1 is a circular insulating rod, the two ends of the first rod are respectively sleeved with the second rod 2, the second rod is also a circular insulating rod, the two ends of the first rod Be respectively located in the chute of two second rods. As shown in Figure 6, a number of sockets 11 are respectively provided at both ends of the first rod, and bolts 7 are respectively provided on the outer wall of the second rod, and the first rod and the second rod can be realized when the screw rod of the bolt is inserted into the socket The rod is relatively fixed. For the convenience of bolt installation, one end of the second bar is provided with a notch 21, and the bolt is arranged in the notch, and the second bar at the notch position is provided with a threaded hole, and the bolt is placed in the threaded hole.

As shown in Figure 2, the free end of the second rod is also a hollow structure, and a first baffle plate 32 and a second baffle plate 33 are arranged in the cavity of the free end of the second rod, and the profiles of the first and second baffle plates Adapt to the shape of the inner cavity of the free end of the second rod. Wherein, the first baffle is placed on the end surface of the free end of the second rod, and the second baffle is placed inside the free end of the second rod. A guide pipe 34 is arranged between the first baffle plate and the second baffle plate, and a through hole is provided on the first baffle plate, and a latch 4 is arranged in the through hole, and the latch can slide in the through hole, and at one end of the latch A positioning plate 43 is provided, and the positioning plate is slidably installed in the casing, and the aperture of the through hole is smaller than the inner diameter of the guide tube, so as to prevent the latch from slipping off from the guide tube. One end of the bolt is placed in the guide tube, the other end of the bolt is placed outside the second rod, and one end of the bolt placed outside the second rod is provided with an inclined surface 41 . On the end face of the free end of the second rod, a connecting plate 31 is fixed, and a top plate 3 is fixed on the free end of the connecting plate, and the top plate and the connecting plate are vertically arranged as shape. The insertion end of the bolt faces the top plate, and a spring 35 is arranged between the positioning plate and the second baffle plate.
