It shown in Fig. 3,4,5 most preferred embodiment of folding toolroom machine of the present utility model.For the purpose of brief and concise, the utility model is that example is illustrated with the mower in the toolroom machine only, and protection domain of the present utility model also not only is confined to mower.

The utility model mower comprises: a power unit 10, a frame 20, a wheel carrier 30 and leader's frame 40.

Power unit 10 be by an engine 11 in an outer tube 12 a driving shaft and the power transmission shaft in the joint 13 drive a cutter 14, its generation is rotatablely moved, to prune weeds, and outer tube 12 is respectively equipped with a T shape connecting rod 121 and and folds seat 122 in the pre-position, folds seat 122 and is provided with an elongated slot 1221 that is lateral openings.

Power unit 10 is erected on the frame 20, and frame top is provided with leader's frame location-plate 21, and handle rack location-plate 21 is provided with three elongated slots 211 that are lateral openings.

Wheel carrier 30, its top is connected with the bottom of frame 20, and with carrying power unit 10 and frame 20, and wheel carrier 30 includes a pair of spacing clamp 31,32, a pair of pole 33,34, a wheel shaft 35 and is located at two wheels 37 at wheel shaft two ends.Two poles 33,34 lower ends are fixed on the wheel shaft 35, and two poles 33,34 upper ends then are provided with two spacing clamps 31 respectively, 32, two spacing clamps 31,32 respectively establish a front stopping edge 311,321 and one back stopping edge 312,322, with respectively with two poles 33,34 are positioned at one folds position and a upright position, wherein pole 33 also is provided with a safe clamp 36, two extension springs 38,39, be connected to spacing clamp 31 upsides and safe clamp 36 downsides and spacing clamp 32 upsides and pole 34 position corresponding to safety clamp 36 downsides, when pole is in the upright position of frame, two extension springs 38,39 lay respectively at two poles 33,34 pivotal point rear sides, and the elastic force of extension spring 38 can make a clasp 361 of safe clamp 36 upsides support in a draw-in groove 313 of spacing clamp 31, makes two poles 33,34 can keep to the upright state of after-frame.

Handle rack 40 has second chief's bar 41, and second chief's bar 41 middle section position places, be one group of upper and lower

involutory cross bar

43,44 to be arranged with the horizontal interlocking of disassembled mode, to increase the rigidity of handle rack 40, and the front end of second chief's bar 41 is with disassembled mode interlocking one box body 44 to be arranged, the front end of box body 44 is to be articulated on the T shape connecting rod 121 of outer tube 12, and the forward and backward two side faces of box body 44 respectively offers circular hole 441 and the slotted hole 442 of center on same axis, passes for the bar 50 of having strong market potential.But the two ends of the bar 50 of having strong market potential respectively are provided with a front-end element 51 of spiral shell setting position and reach and its pivot joint and a rotating rear end member 52, the bar 50 of having strong market potential also is provided with one and supports only nut 53 on the body of rod of box body 44 inside, support and be provided with a compression spring 54 between the leading flank that ends nut 53 and box body 44, borrow the elastic force effect of compression spring 54, can make the rear end member 52 that is positioned at slotted hole 442 outsides and the trailing flank of box body 44 keep a gap, bar 50 slips into elongated slot 211 in order to having strong market potential, and the bar 50 of having strong market potential also is connected with an end of an extension spring 55 of being located at box body 44 inner side, borrow the elastic force effect of extension spring 55, can make it be close proximity to an end of elongated slot 211, before relying on,

rear end member

51,52 relative chucking power can lock together the elongated slot 211 of box body 44 with handle rack location-plate 21, and handle rack 40 is positioned on the handle rack location-plate 21.

As Fig. 6, shown in 7 and consult Fig. 3, when desiring to make handle rack 40 to be converted to when folding state from user mode, can pull rear end member 52 earlier, utilize the variation of its all face thickness, make the distance between the opposing end surface of assisting fixture block 521 and front-end element 51 become big, at this moment, can go out elongated slot 211 with the bar 50 of having strong market potential is traversing, and be the centre of gyration with the tie point of box body 44 and T shape connecting rod 121, handle rack 40 is rotated towards the direction at cutter 14 places, to fold handle rack 40, and the bar 50 of will having strong market potential slips into and folds in seat 122 the elongated slot 1221, and then oppositely pulls rear end member 52, and auxiliary fixture block 521 is inwardly clamped with front-end element 51, box body 44 can be fixed with elongated slot 1221 interlockings that fold seat 122, makes handle rack 40 be positioned to fold on the seat 122.

As shown in Figure 8 and consult Fig. 3, Fig. 4, when desire is converted to wheel carrier 30 when folding the position by the upright position of frame, earlier safe clamp 36 downsides are pulled towards the direction at front stopping edge 311 places, make clasp 361 deviate from draw-in groove 313, again wheel shaft 35 is pulled forward, the elastic force effect of two extension springs 38,39 drives two poles 33,34 and two wheels 37 and rotates towards the direction at cutter 14 places in addition, because two poles 33,34 are subjected to the block of two front stopping edges 311,321 respectively, finally make wheel shaft 35 be positioned at the downside of outer tube 12.

By above explanation, advantage of the present utility model can be summarized as follows:

One, can dwindle the shared space of mower by folding handle rack 40, and handle rack 40 links together with mower still after folding, so needn't look for local collection in addition.And in the time will using mower, only need that handle rack 40 is transferred back to user mode can be operated, and needn't re-assembly, and handle rack 40 just can protect the both sides of cutter 14 after folding, thereby can avoid the operator to collide the danger that cutter 14 is produced unintentionally.

Two, have on the handle rack location-plate 21 and be arranged in parallel and three elongated slots 211 of the different heights off the ground of tool, then by three elongated slots 211 respectively with bar 50 interlockings of having strong market potential, can adjust the height off the ground of handle rack 40 when user mode, use with the operator who cooperates different heights.

Three, when desiring to transport mower, second chief's bar 41 can be disassembled from box body 33, and two

cross bars

42,43 be disassembled come, the mower vanning can be transported like this.

Four, wheel carrier 30 is also collapsible, so more can further dwindle the shared space of mower.

What deserves to be mentioned is,, can make engine 11 drive different instruments, and make mower be converted to the toolroom machine of tool difference in functionality if the joint 13 of mower is changed, with loosen the soil, punching, chaffcutter, deburring, pressure-vaccum fallen leaves and operation such as mix cement.
