DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figures 1 to 3 The foldable push handle of a micro-tiller shown in the figure includes a frame 2 and a push handle tube 3 movably connected by a rotating shaft 1, the end of the push handle tube 3 is fixedly connected to a fixing rod 4, a connecting rod 5 is hinged on the fixing rod 4, the other end of the connecting rod 5 is hinged to a push handle fixing rod 6, the other end of the push handle fixing rod 6 is fixedly connected to a folding tube 7, the end of the folding tube 7 is fixedly connected to a push handle 8, a reinforcement rod 9 is welded between the push handle 8, and a movable sleeve 10 is sleeved on the fixing rod 4, the connecting rod 5 and the push handle fixing rod 6.

[0021] In order to facilitate the fixation of the overall push handle to the frame 2 and to facilitate the folded push handle to be folded and placed on the frame 2, a fixing through hole 11 is opened on the push handle tube 3, and a fixing plate 12 and an adjusting plate 13 are provided on the frame 2. The adjusting plate 13 is provided with an adjusting through hole 14 that matches the fixing through hole 11, and a spring plunger 15 that matches the fixing through hole 11 and the adjusting through hole 14 is provided on one side of the fixing plate 12. At least three adjusting through holes 14 are provided on the adjusting plate 13.

[0022] In order to make the movable sleeve 10 better cooperate with the fixed rod 4, the connecting rod 5, and the push handle fixing rod 6 to facilitate the fixing and folding of the push handle, the diameter of the push handle fixing rod 6 is set to be the same as the diameter of the folding tube 7, the inner diameter of the movable sleeve 10 is the same as the diameter of the push handle tube 3, and the inner diameter of the movable sleeve 10 is larger than the diameter of the folding tube 7.

[0023] In order to ensure that the movable sleeve 10 can just wrap the fixing rod 4, the connecting rod 5 and the push handle fixing rod 6 after being installed, the length of the movable sleeve 10 is set to be greater than the sum of the lengths of the fixing rod 4, the connecting rod 5 and the push handle fixing rod 6.

[0024] In order to make the fixing rod 4 and the push handle fixing rod 6 better cooperate with the push handle tube 3 and the folding tube 7 and make the connection between them more secure, the end of the fixing rod 4 is set to be interference connected with the end of the push handle tube 3, and the end of the push handle fixing rod 6 is set to be interference connected with the end of the folding tube 7.

[0025] In order to facilitate the staff to hold and prevent the staff from slipping when holding the handle, a rubber sleeve 16 is sleeved on the handle of the push handle 8.

[0026] The working process of the utility model is as follows: when the push handle needs to be folded as a whole, the movable sleeve 10 sleeved on the outer wall of the fixed rod 4, the connecting rod 5, and the push handle fixing rod 6 is pulled to be sleeved on the outer wall of the folding tube 7, and the fixed rod 4, the connecting rod 5 and the push handle fixing rod 6 are exposed, so that the push handle 8 is folded toward the frame 2, and then the spring plunger 15 is pulled, and the pin of the spring plunger 15 is contracted. Under the action of the rotating shaft 1, the folded whole push handle can be folded and placed on the frame 2, which not only reduces the floor space but also facilitates its transportation; when the micro-tillage machine needs to be used, the folded whole push handle is turned to one side of the frame 2, and the spring plug 15 cooperates with the fixed through hole 11 and the adjusting through hole 14 to The push handle tube 3 is fixed, and then the push handle tube 3 and the push handle fixing rod 6 are adjusted to be in a straight line, and the movable sleeve 10 is moved toward the push handle tube 3 so that it is sleeved on the fixing rod 4, the connecting rod 5, and the push handle fixing rod 6. Under the action of the movable sleeve 10, the push handle tube 3, the folding tube 7 and the push handle 8 form an integral push handle, which is convenient for the normal use of the micro-tiller. When the height of the push handle is not suitable for the user's height, the angle of the push handle can be adjusted to adapt to the user's height. By pulling out the spring plug 15, the pin of the spring plug 15 is contracted. By adjusting the position of the fixing through hole 11 and the adjusting through hole 14, the angle of the push handle is adjusted, and the push handle is fixed by the pin to suit the user's height.
