The semi-T-shaped sliding block in side, the semi-T-shaped sliding block of the semi-T-shaped sliding block in left side and right side constitute a complete T-shaped slider, and the size of T-shaped slider is small
In the size of car body sliding slot；The on both sides of the middle of right locating piece is respectively provided with a diameter bore, and the arrival end of diameter bore is equipped with spiral shell
The on both sides of the middle of line section, left locating piece is respectively provided with a blind hole at the position for being aligned two diameter bores；The leading portion of positioning pin
Equipped with block, for spring pocket in the middle section position of positioning pin, clamp nut covers the rear fragment position in positioning pin；The leading portion of positioning pin according to
In secondary insertion diameter bore and blind hole, clamp nut is threadedly coupled with thread segment, and block is stuck at the variable diameter position of diameter bore；
Safety pin passes through nut check after sequentially passing through two through-holes of left locating piece.
The beneficial effects of the utility model are: the apparatus structure is simple, it is only necessary to slide into T-shaped slider, skid off car body bottom
Frame sliding slot, the i.e. installation and removal of finishing device, it is simple and efficient to handle.When using the device, suspender belt Hoisting Position is round and smooth song
Face can effectively reduce suspender belt abrasion, improve the service life of suspender belt.Meanwhile during handling, it is not necessarily to operator's human assistance
Hoisting Position, had not only avoided the generation of personal injury, but also saved manpower and time, improved labor efficiency.

Specific embodiment
The utility model is described in further details with reference to the accompanying drawing.
As shown in Figures 1 to 4, the vehicle body bottom frame suspending protector of the utility model includes left locating piece 1, right locating piece
2, two springs 5 of clamp nut 4, two of positioning pin 3, two and safety pin 6；The upper end of left locating piece 1 is equipped with the semi-T-shaped cunning in left side
Block 1-1, the lower end of left locating piece 1 are equipped with groove 1-2, and the side wall of groove 1-2 is smooth curved surface, and left locating piece 1 is groove 1-2's
Two sides are respectively provided with a through-hole 1-3；The upper end of right locating piece 2 be equipped with the semi-T-shaped sliding block 2-1 in right side, the semi-T-shaped sliding block 1-1 in left side and
The semi-T-shaped sliding block 2-1 in right side constitutes a complete T-shaped slider, and the size of T-shaped slider is less than the size of car body sliding slot；Right positioning
The on both sides of the middle of block 2 is respectively provided with a diameter bore 2-2, and the arrival end of diameter bore 2-2 is equipped with thread segment 2-2-1, left positioning
The on both sides of the middle of block 1 is respectively provided with a blind hole 1-4 at the position for being aligned two diameter bore 2-2；The leading portion of positioning pin 3 is equipped with
Block 3-1,5 sets of the spring middle section positions in positioning pin 3,4 sets of the clamp nut rear fragment positions in positioning pin 3；Before positioning pin 3
