Abstract

The invention discloses a gear shifting hand rocker. The hand rocker comprises a fixing body, two wire winding wheels, a handle and a gear shifting mechanism, the gear shifting mechanism comprises a hollow push pull member, the push pull member is provided with a clamping member, the fixing body is provided with a supporting shaft, the push pull member rotatably sleeves the supporting shaft and isconnected with the handle, the two wire winding wheels rotatably sleeve a\ shaft sleeve which is arranged on the supporting shaft, the push pull member or the supporting shaft, and the push pull member can be pushed or pulled to move in the axial direction of the push pull member to allow the clamping member of the push pull member to clamp one of the two wire winding wheels. The push pull membersleeves the supporting shaft, gear shifting operation is achieved through the axial moving of the push pull member to allow the supporting shaft to be taken as a primary load bearing carrier to prevent movement in the axial direction, so that the gear shifting of the hand rocker is stable, the vibration is faint, there exists no noise, and the service life of the hand rocker is longer.

Description

technical field [0001] The invention relates to a hand crank, in particular to a shift hand crank. Background technique [0002] The traditional gear shifter generally has only one main shaft, and the main shaft is equipped with a gear pin. By pushing and pulling the main shaft, the gear pin on the main shaft is matched with the cross gear groove of the shift fork, so as to achieve the shifting of the gear position. Purpose. Although this kind of hand crank for gear shifting is easy to operate, because the gear shift is realized through the axial movement of the entire main shaft, the main shaft and the handle must move when shifting gears, resulting in a relatively large vibration of the hand crank during the gear shifting process. Violent and noisy, the hand crank is easily damaged and has a short service life. For this reason, there is a dual-shaft gear push-pull gearshift hand crank in the prior art, which is additionally provided with a transmission shaft, and uses th...
