Pivoting Puller Clamping Members for Quick Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pullers require inconvenient disassembly procedures, involving unscrewing locking bolts and detaching clamping members from support seats, which complicates user operation.
Innovation Solution
A puller design featuring pivotally and detachably mounted clamping members with a top cover and pressing pieces that allow easy adjustment and locking of clamping members relative to support seats, facilitated by a threaded rod and pivot blocks, enabling quick assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If locking bolts and locking nuts are used to secure clamping members to support seats, then the clamping members are firmly fixed, but the disassembly process becomes complicated and time-consuming
Solution Approach 1:
The patent extracts the locking function from the clamping member assembly by introducing a separate locking bolt that engages with a dedicated locking hole in the support seat. This separates the clamping function (performed by the clamping member) from the locking function (performed by the locking bolt), allowing the clamping member to be easily removed while maintaining secure fixation when locked.
Solution Approach 2:
The patent segments the fixation system into distinct functional components: the clamping member for gripping, the locking bolt for securing, and the locking hole for engagement. This segmentation allows each component to perform its specific function efficiently, with the locking bolt providing strong fixation while being independently removable for easy disassembly.
2Reliability
If multiple fastening components (locking bolt and locking nut) are used to secure clamping members, then the connection is strong and reliable, but the number of parts increases and assembly/disassembly becomes more complex
Solution Approach 1:
The patent extracts the nut component from the traditional bolt-nut fastening system and replaces it with a locking hole integrated into the support seat. The locking bolt engages directly with this locking hole, eliminating the need for a separate nut while maintaining connection reliability through the dedicated engagement feature in the support seat.
3Device complexity
If clamping members are permanently fixed to support seats, then the structure is simple and robust, but the clamping members cannot be removed or repositioned
Solution Approach 1:
The patent introduces a dynamic fixation system where the locking bolt can be inserted to secure the clamping member or removed to allow detachment. The pivot block also provides rotational movement capability, enabling the clamping member to be repositioned around the support seat. This dynamic design allows the structure to switch between fixed and movable states as needed.

AI summary
A puller includes a main body provided with a plurality of support seats, a plurality of clamping members each pivotally and detachably mounted on a respective one of the support seats, a top cover mounted on the main body and provided with a plurality of pressing pieces each pressing a respective one of the clamping members, and a threaded rod extending through the top cover and the main body. Thus, each of the clamping members is pivotable relative to the respective support seat of the main body so as to adjust the inclined angle of each of the clamping members relative to the respective support seat. In addition, each of the clamping members is locked onto and unlocked from the respective support seat easily and quickly.
