The shape of the fixing portion 11 matches the mounting hole 202, and the outer end of the connecting portion 12 is fixedly coupled to the housing 201 by a fastener 70. The connecting portion 12 is substantially U-shaped and includes two plug members 13 which are parallel to each other. The inner ends of the plug members 13 are connected to the fixing portion 11, and the cross-section of each of the plug members 13 is formed into a substantially crescent shape.

 [0033] The sleeve 60 is substantially mounted on the front side of the front end of the vehicle head 200. The sleeve 60 has a cavity 61 at one end. The bottom of the sleeve 60 is provided with a through hole 62, and the fastener 70 is disposed in the cavity 61. Specifically, the fastener 70 is, but not limited to, a nut. By tightening the fastener 70, the fastener 70 is pressed against the bottom of the sleeve 60, and is fixed in the axial direction and the radial direction of the fixed shaft 10 The shaft 10 is limited.

 [0034] The first member 20 is sleeved on the fixed shaft 10, and the first member 20 is non-rotatably connected to the fixed shaft 10. One side surface of the first member 20 is formed with a plurality of first ratchets 21, a plurality of A ratchet 21 is disposed about the axis of the fixed shaft 10. Specifically, a plurality of first ratchet teeth 21 are formed on the front side of the first member 20 (the front side direction in FIG. 1 , that is, the direction in which the ride is facing forward), and the first member 20 has the first ratchet 21 A pin 22 is connected to the center of the first portion 20, and the first member 20 is provided with a through hole 23 through which the connecting portion 12 passes through the outer periphery of the pin 22. The number of the through holes 23 is but not limited to two, two through holes 23 respectively corresponding to the two connectors 13 -1, and the shape of the through hole 23 is matched with the connector 13 , and the plurality of first ratchets 21 are arranged around the axis of the fixed shaft 10 at the pin 22 and the through hole 23 . Outer week. It can be understood that after the two connectors 13 of the connecting portion 12 pass through the corresponding through holes 23 respectively, the first member 20 is sleeved on the connecting portion 12 of the fixed shaft 10, and the first member 20 can be along the fixed shaft 10. The axis moves on the connecting portion 12, and the first member 20 is not rotatable relative to the fixed shaft 10 by the engagement of the through hole 23 and the connector 13.

[0035] The second component 30 is sleeved on the fixed shaft 10 and connected to the handle 300. In the embodiment, the rear side of the second component 30 (ie, the side of the second component 30 facing the first component 20) is formed. a plurality of second ratchet teeth 31 for engaging with the plurality of first ratchet teeth 21, the plurality of second ratchet teeth 31 respectively corresponding to the plurality of first ratchet teeth 21, and the plurality of second ratchet teeth 31 and the plurality The first ratchet 21 engages the weir, and the second member 30 is unidirectionally rotated relative to the first member 20 about the axis of the fixed shaft 10, that is, the first ratchet 21 of the first member 20 and the second ratchet of the second member 30. The engaging member 300 is oscillated in one direction with respect to the front end 200 by the second member 30. It is worth mentioning that, in the embodiment, the one-way swing direction generally swings upward about the axis of the fixed shaft 10, through the first part. The member 20 and the second member 30 enable the handle 300 to swing up quickly and reach the extended position for the user to use, and under the engagement of the first ratchet 21 and the second ratchet 31, the handle 300 does not downward. The reset, therefore, enables the handle 300 to be quickly adjusted to the desired fixed position or angle, greatly improving ease of use.

 [0036] The engaging and disengaging operating member 50 is configured to force the first member 20 to be separated from the second member 30 to disengage the second ratchet 31 from the first ratchet 21. Specifically, the engagement disengagement operating member 50 includes a cover body 51 and a threaded shaft 52 projecting from the center of the cover body 51. The outer end of the pin shaft 22 has a thread for the threaded shaft 52 to be inserted and threadedly coupled to the threaded shaft 52. groove. The cover 51 is disposed at the mouth end of the sleeve 60 and at least partially exposed on the outside of the sleeve 60. The front side of the cover 51 is used for user pressing, rearward along the axis of the fixed shaft 10 (shown in FIG. 1) After the pressure is applied, the engagement disengagement member 50 moves backward, and pushes the first member 20 to move rearward relative to the fixed shaft 10, so that the first member 20 and the second member 30 are separated from each other, the first member 20 and the second member When the second ratchet 31 between the components 30 is disengaged from the first ratchet 21, the second component 30 can be reversely rotated, that is, the second ratchet 31 can be disengaged from the first ratchet 21, and the handle 300 can be disengaged. The axis is swung downwardly about the axis of the fixed shaft 10.

 [0037] The elastic member 40 is configured to press the first member 20 against the second member 30 to keep the first ratchet 21 engaged with the second ratchet 31, and the elastic member 40 is coupled to the first member 20. Specifically, the elastic member 40 is, but not limited to, a compression spring. The elastic member 40 is disposed in the cavity 61. One end of the elastic member 40 abuts on the inner side surface of the cover body 51, and the other end abuts against the concave portion of the sleeve 60. The bottom surface of the cavity 61. It can be understood that, when the pressure is applied to move the engagement release operating member 50 backward relative to the fixed shaft 10, the cover 51 presses the elastic member 40 to deform to form an elastic reset for driving the second member 30 to be reset after the applied external force is removed. force.
