Embodiment

Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.

Referring to figs. 1 through Fig. 3, corresponding to the garden tool set of the utility model preferred embodiment, be mower, it mainly comprises first component 13 and second component 21, these first,

second parts

13,21 are respectively chain-drive section 13 and handle portion 21.In addition, between chain-drive section 13 and handle portion 21, rotating mechanism is set, mainly comprise the face that connects 1, the interface 2 on second component 21 and the rotating shaft 10 that are arranged on first component 13, and connect face 1 or interface 2 for the surfaces of revolution 9 in this definition, the surfaces of revolution 9 is mutual vertical with rotating shaft 10.In addition, the handle portion 21 of mower has along its central axis c (Fig. 7) section 17, this section 17 also with three dimensions on the X-Y plane overlaid of custom address.Connect face 1 and/or interface 2 (that is surfaces of revolution 9), become a specific included angle A with this section 17 (that is X-Y plane), the best angle scope of this included angle A is being greater than 0 ° and be less than between 90 °.

With further reference to Fig. 4 to Fig. 8, the flexible member 7 that be also provided with chute 4 in above-mentioned handle portion 21, is slidably arranged on the push button 3 in chute 4 and is connected with push button 3.Push button 3 is fixedly connected by connecting rod 16Yu location division 11.Chain-drive section 13 is provided with the face of connecting 1, connecting at least one locating slot 15 that is provided with the first through hole 32 on face 1 and is positioned at the first through hole 32 sides, the optimal number of this locating slot 15 is 2, be wherein positioned at the first through hole 32 left sides be 90 ° of locating slot ，Er right sides be 0 ° of locating slot.Handle portion 21 is provided with interface 2, is provided with the second through hole 35 and extends in outside interface 2 with the 11，Gai location division, location division 11 that is positioned at the second through hole 35 sides on interface 2, and location division 11 optionally snaps in above-mentioned corresponding locating slot 15.In addition, be respectively provided to a few groove 25 on first, second through

hole

32,35 perisporiums, these groove 25 optimal numbers are 4.

The rotating mechanism of above-mentioned garden tool set also comprises the connector 40 that chain-drive section 13 is connected with handle portion 21.On the outer wall of these connector 40 one end, be provided with at least one projection 43, the optimal number of this projection 43 is also 4, and it can be through corresponding groove 25 on first component 17 and second component 18.The other end at connector 40 arranges baffle plate 41.Projection 43 correspondences on connector 40 corresponding recesses 25 and are passed successively described first and second through

hole
