a first convex edge extending downwards is formed at the first end of the third plate, and a second convex edge extending upwards is formed at the second end of the third plate;
the second connecting part of the second boss is inserted into the first through hole of the first connecting plate, and the second stopping part of the second boss is positioned at the lower side of the first connecting plate;
the first connecting part of the first boss is inserted into the second through hole of the second connecting plate, and the first stopping part of the first boss is positioned at the lower side of the second connecting plate;
the third plate block can be inserted in the third through hole in an inserting and pulling manner.
Preferably, a first supporting platform is formed at the lower side of the first plate, and the first supporting platform extends along the front-rear direction of the first plate and is located at the first end of the first plate.
Preferably, the first and second supports are of the same height.
Preferably, the first and second panels are of equal size.
The first plate and the second plate of the stretcher can rotate relatively, and the third plate can be partially inserted into the second plate, so that the stretcher can be bent and stretched when necessary.

Detailed Description
The stretcher of the present application will be described in detail with reference to the accompanying drawings.
The stretcher comprises a first plate 10, a second plate 20 and a third plate 30 which are connected in sequence.
A first pin 11, a first boss 14 and a first connecting plate 12 are formed on the lower side of the first plate 10; the first boss 14 includes a cylindrical first connecting portion 14a and a circular truncated cone-shaped first stopper portion 14 b; the first boss 14 is provided at the front of the first panel 10; the first pin 11 is arranged at the rear part of the first plate 10; a first end of the first connecting plate 12 is rotatably fixed to the first pin 11; the first connecting plate 12 is formed with an elongated first through hole 13.
A second pin 21, a second boss 24, a second connecting plate 22 and a second support platform 25 are formed on the lower side of the second plate 20; the second boss 24 includes a cylindrical second connecting portion and a truncated cone-shaped second stopper portion; the shape and size of the second boss are completely the same as those of the first boss. The second boss 24 is provided at the rear of the second panel 20; the second pin 21 is arranged in front of the second plate 20; a second end of the second connecting plate 22 is rotatably fixed to the second pin 21; the second connecting plate 20 is provided with a second through hole 23 in a long shape; the second support platform 25 extends along the front-rear direction of the second plate 20 and is located at the second end of the second plate 20; a third through hole is provided in the second support table 25.
A first end of the third plate block 30 is formed with a first convex edge 31 extending downward, and a second end of the third plate block 30 is formed with a second convex edge 32 extending upward.
The second connecting portion of the second boss 24 is inserted into the first through hole 13 of the first connecting plate 12, and the second stopper portion of the second boss 24 is located at the lower side of the first connecting plate 12.
The first connecting portion of the first boss 14 is inserted into the second through hole 23 of the second connecting plate 22, and the first stopper portion of the first boss 14 is located at the lower side of the second connecting plate 22.
The third plate 30 is insertably inserted into the third through hole as shown in fig. 2.
A first supporting platform 15 is formed at a lower side of the first plate 10, and the first supporting platform 15 extends in a front-rear direction of the first plate 10 and is located at a first end of the first plate 10.
The first and second supports 15, 25 are of the same height. The first and second panels 10, 20 may also be identical in shape and size.
Magnets may be provided on the facing end faces of the first and second panels 10, 20 to attract the two closely together, but only to separate from each other when bending is required.
The normal use state is shown in fig. 1 and 2. When the stretcher needs to be bent and contracted to pass through a narrow corner, as shown in fig. 4, the first plate and the second plate are separated by a certain angle, at the moment, the first boss slides relative to the second through hole, the second boss slides relative to the first through hole, and the sliding distances are unequal, so that an included angle is formed between the first plate and the second plate, and the stretcher presents a bent shape. During the sliding process, the first connecting plate and the second connecting plate correspondingly rotate relative to the first pin and the second pin. The length of the whole stretcher can be changed by plugging and unplugging the third plate.
