The invention discloses a transmission system, comprising: a driving gear capable of rotating around a first axis; a driven assembly at least having a first state capable of synchronously rotating with the driving gear and a second state capable of relative rotation with the driving gear ; Wherein, the driving gear is formed with a plurality of transmission teeth in its circumferential direction; the driven assembly includes: an elastic member, which is formed with an embedded part that can be embedded between two transmission teeth; The first accommodation chamber and the second accommodation chamber for accommodating part of the elastic member; the first accommodation chamber communicates with the second accommodation chamber; when the driven assembly is in the first state, the elastic member is partially embedded in the first accommodation chamber and connected with the active The gears are in contact; when the driven component is in the second state, the elastic member elastically deforms and disengages from the cooperation with the driving gear. The invention also proposes a garden tool with the transmission system, and the garden tool has the effect of overload protection.
Description
technical field [0001] The invention relates to a garden tool and a transmission system arranged therein. Background technique [0002] In order to realize its functions, garden tools often have relatively high power, such as pruners and lawn trimmers. Garden tools are often blocked by thick branches or other hard objects when they are working, so that the garden tools are blocked and cannot operate normally. , its transmission system and tool accessories used to realize tool functions are easily damaged, which affects the service life of garden tools. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a garden tool with overload protection and its transmission system. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A transmission system comprising: [0006] The driving gear can rotate around the first axis; ...
