See also Fig. 1 and Fig. 2, the utility model includes members such as handspike 1, joint, the left and right sides 2, skeleton 3, crossbeam 4, glove plate 5, wheel carrier 6 and wheel 7, wherein:

Handspike 1 is a Jiong type body of rod, respectively is provided with connecting bore 11 in two tail ends, and connects a cross bar 12, and in handspike 1 terminal cover unification cap stopper 13;

Joint 2 is the block of a tool clip effect, and mat screw 20 is articulated in skeleton 3 head ends, block internal shaping one deep-slotted chip breaker 21, and protrude out a catch 23 in pivoted hole 22 lower edges; Joint 2 can rotate with clip handspike 1 by 90 degree;

As shown in Figure 3;

Skeleton 3 is the body of rod of a left-right symmetric, and its head end is made as a Jiong type cross section flat end 31, and wears a pivoted hole 311 in the recess of flat end 31, articulates handspike 1 to cooperate an axostylus axostyle 32 and packing ring 33; And in the suitable circular hole 312 of establishing of flat end 31 lower edges, for being pivoted of joint 2; A faucet pipe 34 extends in body of rod hypomere system outwards bending, and is equipped with circular hole 313,314,315,316 on bending place and rear faucet pipe 34; And terminal socket one cap stopper 35;

Crossbeam 4 is a rectangular lamellar body, and two ends are fixed on the skeleton 3 with screw 40, and the stage casing is provided with and can uses for colluding solid rope being referred to as through hole 41 and grooving 42;

Glove plate 5 is the plate body of a tool hollow out open-work 51, a vertical surface 52 is shaped in the plate body rear end, and relief has two arc edge 521 on the vertical surface 52, the both sides of vertical surface 52 then respectively are convexly equipped with a pivot connecting seat 53, and in pivot connecting seat 53 front ends respectively be shaped up and down a V-shaped groove 531 and n-type groove 532, mat one latch 54 is articulated in the circular hole 316 of skeleton 3 tail ends in addition;
