Disengaging adjustable safety handle

Abstract

The invention discloses a disengaging adjustable safety handle. The disengaging adjustable safety handle comprises a rocker, a substrate, an oscillating head which is provided with a start shaft sleeve, a base plate and an outer sleeve, and a fixing seat which is connected with an internal-combustion engine body; the start shaft sleeve is fixedly connected with the substrate; the base plate, and the outer sleeve are sleeved on the start shaft sleeve; the start shaft sleeve has a hollow structure which is provided with a through hole axially; the through hole penetrates through the start shaft sleeve and the substrate and a start shaft is inserted into the through hole; one end of the start shaft corresponding to the fixing seat passes through the through hole, and a start bolt used for rotating and starting an internal-combustion engine is protruded on the part of one end of the start shaft passing through the through hole; the other end of the start shaft is provided with a radial positioning piece; on the end face of the substrate which is back to one side of the start shaft sleeve, a radial positioning groove into which the start shaft sleeve can be embedded adaptively is formed at the position corresponding to the radial positioning piece; the end face of one end of the start shaft which is provided with the radial positioning piece is provided with a bolt connection hole, and an axial positioning bolt which is in bolt connection with the bolt connection hole; the axial positioning bolt is in bolt connection with a bottom mad and a nut; and the bottom mad is positioned between the nut and the start shaft and is fixedly connected with the substrate. The disengaging adjustable safety handle is suitable for internal-combustion engines with different shaft depths.

Description

technical field [0001] The invention relates to an internal combustion engine starting tool, in particular to a detachable adjustable safety handle. Background technique [0002] The hand-operated internal combustion engine starting tool in the prior art is only suitable for starting internal combustion engines with a shaft depth because the axial position of the axis of the starting sleeve is fixed and cannot be adjusted, and cannot be widely used to start various internal combustion engines. At the same time, the internal combustion engine often starts to reverse in the process of manual starting, and the accidents caused by the reverse rotation of the starting rocker occur from time to time. For this reason, some safety rockers that can prevent the reverse rotation of the starting have also appeared on the market. However, the structures of these safety rockers are all too complicated, and the cost is also high, so it is not conducive to production and is also unfavorable...

[0002] The hand-operated internal combustion engine starting tool in the prior art is only suitable for starting internal combustion engines with a shaft depth because the axial position of the axis of the starting sleeve is fixed and cannot be adjusted, and cannot be widely used to start various internal combustion engines. At the same time, the internal combustion engine often starts to reverse in the process of manual starting, and the accidents caused by the reverse rotation of the starting rocker occur from time to time. For this reason, some safety rockers that can prevent the reverse rotation of the starting have also appeared on the market. , but the structures of these safety rockers are too complicated and the cost is high, so it is not conducive to production or sales
