Description

Technical Field

[0001] The invention relates to the technical field of injection molding manufacturing, in particular to an internal framework of a valve seat gear lever ball head. Background Art

[0002] The automobile transmission gear lever fixing seat is mainly used for the fixed support and limit of the manual transmission gear lever. Usually, the fixing seat is fixed to the vehicle body floor with bolts. The center of the fixing seat is designed as an inner arc spherical cavity. The ball of the gear lever is wrapped by the spherical cavity and fixed in the fixing seat to form a lever-type fulcrum. When one end of the lever is pulled, the other end of the lever transmits the force to the transmission shift fork through the fulcrum. The gear shift fork swings to achieve the engagement and separation of the transmission shaft system, thereby achieving the purpose of automobile shifting. The existing plastic ball bowl is easy to be loosely fixed to the lever ball due to wear and tear, causing safety hazards of shifting gears. Summary of the invention
