Description

A kind of handheld operating apparatus

Technical field

The utility model relates to a kind of handheld operating apparatus, especially a kind of electronic cutting device.

Background technology

Usually, the roller that all is provided with supporting tool and is used for walking on outdoor gardening class such as grass mower, the mower cutting tool on ground, this type of roller is arranged to adjustable form usually, be used for when cutting operation needs, regulate the relative distance between roller and the ground, thereby the height that changes between cutting tool and the ground plant satisfies the height of mowing.

Announce No. 200953749 patent as Chinese patent and disclosed a kind of mower of regulating the roller position, it comprises main body and push rod, wherein pusher section includes the expansion link of handle and connection handle and main body, main body partly includes casing and includes the working head of rotating disk, nylon rope, the outside of working head is provided with protective cover, the adjustable roller up and down that the both sides of protective cover are adorned respectively.Wherein rolling wheel regulator comprises a support, and support and protective cover corresponding is provided with the hole that several are vertically arranged, and a connecting axle with the wheel cap close-fitting passes the described support tight fit that is located at the protective cover inboard of Kong Houyu of the centre bore and the protective cover of roller.Owing to have the roller of two support machines, and two rollers can be adjusted up and down, thereby not only help in operator's use keeping machine steadily, alleviate the burden that lifts machine, and pass through the adjustment of the upper-lower position of roller, can change the mowing height that the distance between working head and ground is satisfied the demand.

Chinese patent is announced patent No. 2712068 for another example, its specification has disclosed a kind of height adjusting mechanism of hand-held grass mower, it is characterized in that, on the grass mower pedestal, be provided with a guide groove that runs through the pedestal both sides, described pedestal has locating hole in the both sides of guide groove respectively along the guide groove bearing of trend, a flute profile supporting seat, its both sides cell wall does not have base bottom to insert in the pedestal, and corresponding respectively guide pillar that passes guide groove and the projection of inserting locating hole of being provided with on this both sides cell wall, when grass mower when cutting grass, be supported on the meadow by this flute profile supporting seat,, obtain required shear height by regulating the height of flute profile supporting seat.

The roller of the mower that first preceding case discloses is owing to be arranged at the both sides of protective cover respectively, and therefore when execution was highly regulated, the roller that need regulate both sides respectively was to corresponding height and position; And in adjustment process, need earlier connecting axle to be transferred to, and then the corresponding hole on insertion protective cover and the support; Such operation sequence is very loaded down with trivial details, and is also very consuming time, do not utilize cutting operation effectively.

The grass mower of second preceding case announcement is when carrying out cutting operation, its supporting seat is supported on the meadow, the supporting surface of a broad of supporting seat tool, grass mower just can obtain a stable support, when supporting seat carries out in ground will producing friction between supporting surface and the ground when mobile, this frictional resistance will have influence on operation and operating efficiency, and the gear adjustment structure relative complex of its height, operation are also inconvenient.
