Description

Roller mechanism of lawn trimmer

Technical Field

The utility model relates to a lawn trimmer, specific gyro wheel mechanism of lawn trimmer that says so.

Background

The existing common edge trimmer adopts a hand-push type, a power mechanism is arranged at the rear end of a push rod, the front end of the push rod is connected with a machine head, the machine head is fixed at one side of a blade shield, a roller mechanism is arranged behind the blade shield and consists of a roller fixing part and a roller arranged on the roller fixing part, when the edge trimmer is used, a worker carries the roller on a handle on the power mechanism by hand to push the roller to trim the lawn, however, the height of the roller of the existing lawn edge trimmer cannot be adjusted, the blade of the lawn edge trimmer can only be kept horizontal by the height of the worker carrying the power mechanism by hand, the power mechanism is originally heavier in weight, and the lawn edge trimmer is easy to fatigue if the worker needs to bend or bend the arm to trim the lawn.

SUMMERY OF THE UTILITY MODEL

In view of the defect that its gyro wheel of current lawn trimmer highly can't be adjusted, the utility model aims to solve the technical problem be: provided is a roller mechanism of a lawn trimmer, the height of which can be adjusted.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: a roller mechanism for a lawn edger, comprising:

the roller fixing part is provided with a vertical strip-shaped through groove;

the roller is provided with a central hole, a rolling sleeve is arranged in the central hole, the roller can rotate around the rolling sleeve, and meanwhile, two end parts of the rolling sleeve extend out of two ends of the central hole of the roller;

the adjusting knob is composed of a knob handle and a bolt which are separated, the bolt sequentially penetrates through the strip-shaped through groove, the gasket II, the rolling sleeve, the gasket I and the knob handle and then is fixed with the nut, and the rolling sleeve is fastened by the knob handle through rotating the nut.

According to the roller mechanism of the lawn trimmer, the vertical strip-shaped through groove is formed in the roller fixing part, and after the nut is loosened, the bolt can move up and down to adjust the height of the roller.

Furthermore, one side of the knob handle opposite to the rolling sleeve is provided with a resisting head, the knob handle is propped against the rolling sleeve through the resisting head, the other side of the knob handle opposite to the resisting head is provided with a nut hole, and the shape of the nut hole is the same as that of the nut, so that the nut can be placed in the nut hole. The design structure is more reasonable, and meanwhile, the service life of the nut is prolonged.

Furthermore, its one end of keeping away from the interlude of bolt is equipped with the dop, and the dop card is in the logical inslot of bar. The above design is to prevent the jumping force of the roller wheel from being larger than the fastening force to move the bolt when the roller wheel jumps.

Further, the chuck is quadrilateral. The above design facilitates bolt installation.

Compared with the prior art, the utility model has the advantages of: the height of the idler wheel is adjustable, the lawn trimmer is suitable for workers with different heights to use the lawn trimmer at the most comfortable angle, and the working efficiency is improved.
