Angular adjustment dish 70 is fixed on special-shaped ring 73 by locking member 74, is namely fixed on connecting rod 10.
Please with reference to Figure 15, locking member 74 includes set lever 741 and locking pull bar 742. Set lever 741 is the cam with handle body or eccentric wheel structure, and the present embodiment adopts cam structure, and locking pull bar 742 is connected on set lever 741, and set lever 741 is around locking pull bar 742 radial rotating. Locking pull bar 742 sequentially passes through circular hole 731 and arc-shaped slot 72. Locking pull bar 742 in the present embodiment is threaded rod, and locking pull bar 742 is connected to nut at the opposite side of angular adjustment dish 70, for making the position of locking pull bar 742 and nut remain unchanged, plays screw thread glue and reinforce on nut.
As shown in figure 14, when depressing set lever 741, not having gap between set lever 741, special-shaped ring 73 and angular adjustment dish 70, special-shaped ring 73 and angular adjustment dish 70 are clamped by set lever 741. As shown in figure 15, when lifting set lever 741, having gap between set lever 741, special-shaped ring 73 and angular adjustment dish 70, angular adjustment dish 70 can rotate on locking pull bar 742. The locking member 74 position on special-shaped ring 73 remains constant.
Please with reference to Figure 16, when lifting set lever 741, rotational angle adjustment disk 70, so that work chamber 20, blade 30, arc support 60 and assembly thereof together rotate, electric hedgerow machine 100 is in folded state.
The operation principle of electric hedgerow machine 100 is: being connected to blade 30 on work chamber 20, the link position of blade 30 and work chamber 20 remains unchanged. Arc support 60 one end is connected with work chamber 20, and the other end is connected with the end of blade 30, is namely considered as arc support 60 and is connected to the two ends of blade 30. Arc support 60 rotates around work chamber 20. Blade 30 is fixed near one end of work chamber 20, and the other end is driven by arc support 60 and rotates, thus blade 30 is deformed.
Owing to blade 30 end deformation when deformation is likely to less, adding trimming assembly 63 and regulate the deformation of blade 30 end, the deformation making electric hedgerow machine 100 is more perfect.Slide block assembly 32 on blade 30 can extend the service life of blade 30. For the ease of the user demand carried and deposit and under some specific environment, electric hedgerow machine 100 is additionally provided with angular adjustment dish 70, regulates blade 30 together with the angle between arc support 60 and connecting rod 10. Have employed the cam structure locking member 612,64,74 of three positions to fasten to the position reaching movable part.
The electric hedgerow machine of the present invention adds arc support on blade with work chamber, arc support one end can rotate relative to work chamber, blade is made to be deformed when rotated, blade is made also to have certain radian, by locking member by arc support locking position, the radian namely making blade is fixed, thus reaching straight snips and the round effect cutting two and. The electric hedgerow machine simple in construction of the present invention, easy to use, work efficiency is high, environment friendly and pollution-free, be that a kind of straight snips that can be used as also is used as the electric hedgerow machine that circle is cut.
In all examples being illustrated and described herein, any occurrence should be construed as merely exemplary, and not as restriction, therefore, other examples of exemplary embodiment can have different values.
It should also be noted that similar label and letter below figure represent similar terms, therefore, once a certain Xiang Yi accompanying drawing is defined, then it need not be carried out definition further and explain in accompanying drawing subsequently.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention. It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention. Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
