Embodiment 1

[0028] combined with Figure 1-6 As shown, a telescopic mechanism of a hand-held weeder includes a hand-held rod 1 and a moving rod 2 on which the weeder is installed. The motor of the switch, the rotating shaft of the motor is connected with a screw 3, the screw 3 is connected with the moving rod 2 and the axis line of the screw 3 is parallel to the long axis of the moving rod 2.

[0029] The present invention is a new telescoping mechanism of a hand-held weeder. A moving rod 2 is set inside a hand-held rod 1 to control the relative movement of the moving rod 2 and the hand-held rod 1 to realize telescoping. A motor is installed in the hand-held rod 1 and connected to Power supply and switch, through the switch to control the forward and reverse rotation of the motor, the screw rod 3 connected to the motor is driven to rotate, and the screw rod 3 is connected to the moving rod 2, and the rotation of the screw rod 3 makes the position of the moving rod 2 and the hand-held rod ...

Embodiment 2

[0031] This embodiment is based on the above embodiments, combined with the attached Figure 2-4 As shown, further defined, the side wall of the moving rod 2 is provided with a mounting groove 21, the bottom of the mounting groove 21 is installed with a spring 4, and the end of the spring 4 away from the bottom of the mounting groove 21 is connected to the A key 5 , the side wall of the handle bar 1 is provided with an A groove 11 matching with the A key 5 . Wherein the connection of installation groove 21, spring 4 and A key 5 makes the movement of moving rod 2 partially limited, thereby can move according to the direction required, and A key 5 can compress spring 4 and enter the inside of installation groove 21 to generate in moving rod 2 It is not affected by exercise.

[0032] Other parts of this embodiment are the same as those of the foregoing embodiments, so details are not repeated here.

Embodiment 3

[0034] This embodiment is based on the above embodiments, combined with the attached figure 2 As shown, it is further defined that the A key 5 includes an A part 52 and a B part 51 connected to the spring 4, and the surfaces of the A part 52 close to the motor and away from the motor are both wedge-shaped surfaces and the two wedge-shaped surfaces are "eight" The "eight"-shaped bottoms of the two wedge-shaped surfaces are connected to the B part 51, and the B part 51 is installed in the installation groove 21. Wherein, the wedge-shaped surface of "eight" shape is set, so that the moving rod 2 can be stretched or retracted without locking when moving in the required direction.

[0035] Other parts of this embodiment are the same as those of the foregoing embodiments, so details are not repeated here.

Abstract

The invention discloses a telescopic mechanism for a hand-held weeding machine. The telescopic mechanism comprises a hand-held rod and a moving rod provided with the weeding machine, the moving rod issleeved with the hand-held rod, a motor connected with a power supply and a switch is installed in the handle-held rod, a screw rod is connected to a rotating shaft of the motor, the screw rod is connected with the moving rod, and the shaft axis of the screw rod is parallel to the long axis of the moving rod. The problem that the length of the hand-held part of the hand-held weeding machine cannot be adjusted is solved.

Description

technical field [0001] The invention relates to the field of weeders, in particular to a telescopic mechanism for a hand-held weeder. Background technique [0002] While the crops in the field are growing, the weeds are also growing and competing with the crops for water, fertilizer and sunlight, and some weeds are more vigorous than the crops and can even replace the crops. If the weeds are allowed to grow, the crops will suffer Reduced yield or even no harvest; the traditional weeding method is manual weeding, which consumes a lot of physical labor; some areas use herbicides to weed, which can inhibit the growth of weeds to a certain extent, but herbicides The chemical composition of the grass also brings corresponding side effects to the crops and the environment; although the weeder driven by the power device such as a tractor has high work efficiency, the production cost is high, which is difficult for ordinary people to bear, and the machine is bulky, and most of them ...
