Embodiment

The utility model is further described with reference to Figure of description.

Referring to shown in Fig. 1-2, including shift fork 2 outside square shaft 1, clutch, shift fork 3, handle brackets 4 in clutch.Wherein, in clutch Shift fork 3 coordinates with the outer shift fork 2 of clutch, and square shaft 1 is matched through shift fork 3 in clutch, and its one end extends to the outer shift fork 2 of clutch Interior, the other end extends in handle brackets 4 and matched.

, can by the way that both ends through shift fork 3 in clutch and are respectively placed in outside clutch in shift fork 2 and handle brackets 4 by square shaft 1 , can be by stretching out or retracting square shaft 1 when being installed on the door-plate of different-thickness so that longer square shaft 1 to be stored, can be with Same root square shaft 1 is applied to the door-plate of different-thickness, improve installation effectiveness and reduce production cost.

Specifically, one end of the outer shift fork 2 of clutch is provided with the first circular hole 21, one end of shift fork 3 and the first circular hole 21 in clutch It can be rotated with merging in the first circular hole 21.Shift fork 3 can be relative to the self-movement of shift fork outside clutch 2 so in clutch.

Specifically, shift fork 3 is provided with the first groove 31 to match with square shaft 1, the first circular hole of the outer shift fork 2 of clutch in clutch 21 bottom is provided with the first inner chamber 22 that can accommodate square shaft 1, and square shaft 1 penetrates the first groove 31, and its one end extends to first inner chamber 22 and can in first inner chamber 22 rotate.So by the way that one end of square shaft 1 is inserted into shift fork outside clutch again through shift fork 3 in clutch In 2, the square shaft 1 of additional length can be stored, and the rotation of the outer shift fork 2 of clutch will not directly drive square shaft 1 to rotate, and not interfere The work of the outer shift fork 2 of clutch.

Specifically, handle brackets 4 are provided with the second inner chamber 41 to match with square shaft 1.So can be by the other end of square shaft 1 Unnecessary length is received in handle brackets 4.

Further, in addition to for limiting square shaft 1 alignment pin 5 being axially moved, square shaft 1 are provided with relative with alignment pin 5 The positioning hole 11 answered, shift fork 3 is provided with through hole 32 in clutch, and through hole 32 runs through groove 31, and alignment pin 5 passes through through hole 32 and positioning hole 11 coordinate.By the cooperation of alignment pin 5 and positioning hole 11, can be fixed on square shaft 1 in clutch prevents axial direction on shift fork 3 Slide.Positioning hole 11 is set into ad-hoc location or specific quantity, can quickly adjust effective length that square shaft 1 is adapted to door-plate thickness Degree.

In the present embodiment, 2 positioning holes 11 can be set on square shaft 11, and a positioning hole 11 is provided close to square shaft 1 Middle part, another positioning hole 11 is provided close to the end of square shaft 1, and larger door-plate 8 is differed for adjusting two thickness ranges Installation.

Referring to Fig. 3, when square shaft 1 selects the positioning hole 11 close to middle part to be fixed with shift fork 3 in clutch, by adjusting square shaft 1 other end stretches out or the second inner chamber 41 of retraction handle brackets 4, can be with the door-plate 8 in suitable thicknesses smaller range.

Referring to Fig. 4, when square shaft 1 selects the positioning hole 11 close to end to be fixed with shift fork 3 in clutch, by adjusting square shaft 1 other end stretches out or the second inner chamber 41 of retraction handle brackets 4, can be with suitable thicknesses interior door-plate 8 in a big way.

Referring to Fig. 2, when applying to the installation of door-plate 8, square shaft 1 is passed through into door-plate 8, its one end coordinates solid with shift fork 3 in clutch Fixed, shift fork 3 coordinates with the outer shift fork 2 of clutch in clutch, and outer handle 6 does not coordinate another with the outer shift fork 2 of clutch with shift fork in clutch 3 End coordinates, and the other end coordinates with handle brackets 4, and one end that handle brackets 4 do not coordinate with square shaft 1 coordinates with Internal handle 7.

The above is only some embodiments of the present utility model.For the person of ordinary skill of the art, not On the premise of departing from the utility model creation design, various modifications and improvements can be made, these belong to the utility model Protection domain.
