Garden Tool Attachment Lifting Lock for Quick Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garden tools with single function modules have limited usage across seasons, leading to reduced utilization, as attachments like snow throwers need adjustable positions for effective operation.
Innovation Solution
An adjusting device with a lifting mechanism and locking mechanism allows the attachment to switch between positions, facilitated by a pedal assembly and assisting mechanisms, enabling convenient adjustment between operational and elevated states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a garden tool has only a single function module, then the structure is simple, but the usage rate is reduced due to seasonal limitations
Solution Approach 1:
The garden tool is designed with a universal mounting mechanism that can accommodate multiple different attachments (snow thrower, cultivator, etc.), allowing a single base tool to perform multiple functions across different seasons and tasks, thereby improving usage rate without requiring multiple separate tools
2Adaptability or versatility
If the attachment position is fixed, then the structure is simple, but the use effect is compromised when obstacles are present
Solution Approach 1:
The attachment mounting system incorporates a dynamic adjustable mechanism with lifting and locking devices that enable the attachment position to be changed from fixed to movable, allowing the attachment to be elevated over obstacles or lowered for ground-level work, improving adaptability to different working conditions
3Adaptability or versatility
If the attachment adjusting device is complex, then the position adjustment capability is improved, but the operation convenience is reduced
Solution Approach 1:
The adjusting device incorporates a self-locking mechanism with spring-loaded locking members and toggle structures that automatically lock the attachment in position after adjustment, eliminating the need for continuous manual force or complex control systems, thereby maintaining ease of operation while achieving reliable position adjustment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the practicality of garden tools by allowing attachments to be easily positioned for various tasks, improving usage rates and reducing maintenance costs by enabling multi-season functionality.
Implementation Method 1
a reset mechanism connecting the fixing portion and the locking portion... two ends of the reset mechanism fix to the fixing portion and the locking portion respectively
Implementation Method 2
a pedal assembly rotatably mounted to the shaft assembly... the pedal body is rotationally retained to the connecting portion via the pedal bracket
Implementation Method 3
the other end of the locking portion is provided with a toggle structure used for separate the locking mechanism from the pedal assembly

AI summary
The invention relates to an adjusting device, which includes a lifting device for adjusting a position of an attachment in use and a locking mechanism. The lifting device is switched between a locking position and a free position under a locking action of the locking mechanism, the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position. The adjusting device of the present invention has a simple structure, a low production cost, an easy maintenance, and a garden tool using the adjusting device can conveniently and quickly adjust the position of the attachment connected to the garden tool.
