Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, a caster locking mechanism includes a casing, a caster assembly 1, a lock block 4 and a knob 5. The caster assembly 1 is composed of a front wheel 11 and a connecting arm 12. The upper end of the connecting arm 12 is connected to the machine On the casing, the lower end of the connecting arm 12 is connected with the wheel shaft of the front wheel 11. The casing is formed by combining the left and right casings 2 and 3, and the left and right casings 2 and 3 are provided with through holes. The upper end of the connecting arm 12 and the lock block 4 are arranged in the arc-shaped groove formed by the combination of the left and right casings 2 and 3. The upper end of the connecting arm 12 is disc-shaped, and its center is provided with a The through holes on the right casing 2, 3 correspond to the through hole...

Abstract

The invention relates to a caster locking mechanism, which comprises a shell and a caster component, wherein the caster component consists of a front wheel and a connecting arm; the upper end of the connecting arm is connected to the shell; the lower end of the connecting arm is connected with a wheel shaft of the front wheel; the caster locking mechanism is characterized in that the shell is formed by folding a left shell and a right shell; the left shell and the right shell are provided with through holes; the left side of the upper end of the connecting arm and the left shell are adjustably arranged in a cambered groove, which is formed by folding the left shell and the right shell, through tooth surface matching; the right side of the upper end of the connecting arm is axially connected with a locking block; the locking block is provided with a limiting block which is matched with the connecting arm for locking the movement of the connecting arm along the axial direction; a knob which is matched with the locking block is arranged on the outer side of the right shell; and adjustment and locking of the connecting arm are realized through matching of the knob and the locking block. The caster locking mechanism has the characteristics of simple structure, stable and reliable connection and fastness and convenience in adjustment, quick locking and high adjustment of a caster and a body are realized, and the cutting depth of an edge trimmer can be conveniently adjusted.

Description

technical field [0001] The invention belongs to the technical field of garden tools, in particular to a caster locking mechanism of a trimming machine. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the greening level of living and living, and the large-scale ecological green spaces, residential green spaces, and road green spaces in cities are constantly increasing. The edge trimmer is mainly used for lawn trimming and lawn embedding, cutting grooves, slotting, etc. The general edge trimming machine adopts a hand-push type, and the cutting height can be adjusted according to needs. The traditional trimming machine has the defects of complicated adjustment steps and long time consumption, which needs further improvement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a caster locking mechanism with simple structure and quick and convenient ...
