Handball convenient to insert and extract

Abstract

The invention discloses a handball convenient to insert and extract. The handball comprises a clamping sleeve, a handle arranged in the clamping sleeve in a sleeving manner, and an end cover fixed to the upper end of the handle through a fastener, wherein the upper end of the handle is provided with a first ring-shaped clamping slot; the position, which corresponds to the first ring-shaped clamping slot, of the clamping sleeve is provided with a limiting baffle block which is protruded out of the side wall of the clamping sleeve; a ring-shaped bump part which is protruded out of the side wall of the handle is arranged on the middle part of the handle; and the position, which corresponds to the ring-shaped bump part, of the clamping sleeve is provided with a second ring-shaped clamping slot which is sunken into the side wall of the clamping sleeve. According to the handball, a three-section fixing mode is adopted for decomposing force which must be originally borne by one section of a buckle, so that the handball is more uniformly in stress, and is stable; by decomposing, the clamping amount of each buckle can be reduced, so that the assembly force is reduced, and therefore, the handball can be operated by virtue of a simple tool; besides, an oiling process is avoided.

Description

technical field [0001] The invention relates to the field of auto parts, and more specifically, relates to a handball on an auto gear switch. Background technique [0002] The current handball connection method: the TPU handle (TPUSHAFT) is only connected and fixed with the clip sleeve (INSERT). The above connection method has the following defects: [0003] 1) In order to ensure the connection insertion and extraction force requirements, the TPU handle and the clamping sleeve must have a large amount of clamping and clamping, which indirectly leads to difficulty or inability to assemble the handball; even if it can be assembled, it must be assembled with the help of external tooling. large investment; [0004] 2) When assembling, the TPU handle must be greased. After a long time, there is a risk of chemical reaction between the grease and the TPU, which will eventually lead to failure. Contents of the invention [0005] Aiming at the deficiencies in the prior art, the ...
