The invention discloses a drive system, which comprises a driving gear, a driven component and a driven element, wherein the driving gear can rotate by using a first axial line as a rotation axis; the driven component at least has a first state in which the driven component can synchronously rotate with the driving gear and a second state in which the driven component can relatively rotate with the driving gear; multiple drive teeth are formed in the driving gear in the circumferential direction of the driving gear; the driven component comprises an elastic element; an embedment part which can be embedded between two drive teeth is formed in the elastic element; a first accommodating cavity used for accommodating at least part of the driving gear and a second accommodating cavity used for accommodating part of the elastic element are formed in the driven element; the first accommodating cavity communicates with the second accommodating cavity; when the driven component is in the first state, the elastic element is partially embedded in the first accommodating cavity and is in contact with the driving gear; and when driven component is in the second state, the elastic element elastically deforms to disengage from the cooperation with the driving gear. The invention also provides a garden-class tool with the drive system. The garden-class tool has an overload protection effect.
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; ...
