Embodiment
Shown in ginseng Fig. 1,2, garden instrument of the present invention comprises main body 1 and a control crank assembly.The connecting line 4 that this control crank assembly comprises hand-held body 2, connect the extension bar 3 of this hand-held body 2 and main body 1 and be located in this extension bar 3.
Shown in ginseng Fig. 1,2, garden instrument of the present invention is a grass mower form in the following specific embodiments, and described main body 1 was an independent grass mower before unassembled control crank assembly, can work independently.The elements such as this main body 1 comprises housing 11, assemble with housing 11 phase bracket 6, the switch 12 being located at housing 11 inside, motor 13 and battery 14.Garden instrument has the touch part 15 that can touch described switch 12, and this touch part 15 comprises the first touch part 151 and the second touch part 152, and wherein the second touch part 152 directly contacts with switch 12.This second touch part 152 to be rotatably mounted on main body 1 on set rotating shaft O1, and this second touch part 152 has a main part 1520, the contact protuberance 1521 that outwards protrudes out from this main part 1520 and contact the protuberance 1522 that protuberance 1521 oppositely protrudes out with this.Main body 1 is provided with the push button 16 and lift 17 that are used in conjunction with each other, when holding lift 17 after promotion push button 16, the support division 171 of lift 17 will prop up that push button 16 makes it can not resilience, lift 17 will push the second touch part 152 simultaneously, second touch part 152 like this will with described rotating shaft O1 for fulcrum rotates, described protuberance 1522 will compress the button 121 of switch 12 and then starter motor 13.
Shown in ginseng Fig. 3, extension bar 3 inserts in hand-held body 2, and both are bolted together.Hand-held body 2 comprises a housing 20 and the push button 21 be used in conjunction with each other and lift 22, and this push button 21 comprises the hand push portion 210 be positioned at outside described housing 20, the hook-type pushing portion 211 being positioned at housing 20, auxiliary section 212, connects the connecting portion 213 of pushing portion 211 and auxiliary section 212 and be connected the neck 214 of hand push portion 210 and this connecting portion 213.Auxiliary section 212 is in L-type, and its low side towards pushing portion 211 side is provided with a chamfering 215, and in addition, the outer face of auxiliary section 212 is provided with a projection 216, a sheathed spring (non-label) on this projection 216, and the other end of this spring is fixing on the housing 20.Described lift 22 comprises the main part 220 held for operator and the support division 221 extended internally from this main part 220, this support division 221 be provided with back shaft 222 and be oppositely arranged with described chamfering 215 coordinate inclined-plane 223.Lift 22 is also provided with a spring (non-label), the other end of this spring is also fixed on the housing 20.
Shown in ginseng Fig. 1,3, the slide block 25 being also provided with a line retractable apparatus 23, chute 24 in hand-held body 2 and can sliding in this chute 24.One end of described connecting line 4 is extended on the rear back shaft 222 being first erected on described support division 221 in extension bar 3, then through groove (non-label) set in slide block 25, is finally connected with described line retractable apparatus 23.Described extension bar 3 is provided with the regulating part 31 regulating its length, the length of operator by using this regulating part 31 freely can adjust extension bar 3 as required.Described line retractable apparatus 23 is an elasticity winder with line draw-in and draw-off function in the present embodiment, described connecting line 4 volume is established in the inner, therefore when extension bar 3 elongates or shortens, if connecting line in the inner 4 realizes retractable cable by the natural pulling force of line retractable apparatus 23.
Shown in ginseng Fig. 1,2, be arranged with connector 5 outside the other end of extension bar 3, this connector 5 is connected with bracket 6, thus realizes extension bar 3 and be connected on main body 1.The roller 1511 of described first touch part 151 is located on the rotating shaft O2 of bracket 6, and this first touch part 151 is provided with the push rod 1512 extended above roller 1511 and the extension 1513 extended below roller 1511.When extension bar 3 is assembled to main body 1, the push rod 61 on bracket 6 will push seesaw 18, thus make seesaw 18 rotate for fulcrum with rotating shaft O3 and withstand lift 17, and lift 17 like this is just lockable and cannot moves.
Shown in ginseng Fig. 3,4, when the hand push portion 210 of push button 21 is pushed, described pushing portion 211 pushes slide block 25 gradually, slide block 25 is slided in chute 24, connecting line in slide block 25 4 moves until be locked in chute 24 in company with slide block 25 together, so, pushing portion 211, chute 24 and slide block 25 form the line locking device that connecting line 4 can be locked jointly.Now hold the main part 220 of lift 22 again, described support division 221 is made to be held on auxiliary section 212, while support division 221 moves upward, described back shaft 222 upwards pushing tow connecting line 4 thereupon, the one end being positioned at slide block 25 due to connecting line 4 is fixed, therefore the connecting line 4 in extension bar 3 will outwards be stretched, and so, support division 221 and back shaft 222 form the line pull unit that can pull connecting line jointly.Join shown in Fig. 1,2 again, now the first touch part 151 because extension 1513 is subject to pulling of connecting line 4 with rotating shaft O2 for fulcrum rotates, described push rod 1512 pushes the contact protuberance 1521 of the second touch part 152 while rotating, and then making the second touch part 152 be that fulcrum O1 rotates because of stressed with rotating shaft, described protuberance 1522 is just thereupon compressing the button 121 of switch 12 and starter motor 13.
After removing the power be applied on main part 220, lift 22, push button 21 and slide block 25 are all returned to home position, originally the connecting line 4 be locked in chute 24 is released, and reinstatement under the effect of the online natural pulling force of retractable apparatus 23 of connecting line 4, thus the pulling force that connecting line 4 acts on described extension 1513 disappears thereupon, the elastic-restoring force of back-moving spring 62 makes the first touch part 151 get back to home position, and then second touch part 152 home position of also replying, switch 12 button 121 like this is released, and motor 13 stops operating.
Garden instrument of the present invention pulls the extension 1513 of the first touch part 151 to realize the object of remote control switch 12 by control crank assembly, therefore without the need to setting up one by the directly actuated switch of hand-held body as in background technology in hand-held body, thus reduce the manufacturing cost of product, simplify product structure; Secondly, the connecting line 4 in the present invention is not directly connected with switch, and therefore connecting line 4 for the spring wires with conducting function usually used, and must need not be only common nylon wire, steel wire rope or stay cord, thus also reduces the manufacturing cost of product; In addition, because garden instrument of the present invention only establishes a switch, and switch 12 and motor 13 are all located in main body 1, circuit is between the two shorter, thus avoid in background technology and produce the larger problem of pressure drop because the circuit between switch and motor is longer, and then reach the object reducing energy ezpenditure and hoisting machine operating efficiency.In addition, the main body in the present invention can be other garden instruments except grass mower, and namely described control crank assembly can be assembled on different garden instruments.
