The locking device comprises a lining, a locking piece and a handle, the lining is used for being arranged on the outer side of an outer pipe in a sleeving mode, the locking piece is movably arranged on the lining and provided with a first acting structure capable of penetrating through the outer pipe, and the first acting structure can abut against an inner pipe inserted into the outer pipe; the handle is arranged on the lining, the handle is provided with a second acting structure capable of abutting against the locking piece, the handle has a first working state and a second working state, when the handle is in the first working state, the second acting structure abuts against the locking piece to enable the first acting structure of the locking piece to abut against the inner pipe, and when the handle is in the second working state, the second acting structure abuts against the locking piece to enable the second acting structure of the locking piece to abut against the outer pipe. And the locking piece can move on the bushing. According to the locking device, the position, in the outer pipe, of the inner pipe is locked in a jacking mode, the locking strength can be improved, and the problems of part abrasion and inner pipe loosening caused by increase of the use frequency can be reduced.

    本发明具体涉及一种锁紧装置及代步车,该锁紧装置包括衬套、锁紧件和手柄,衬套用于套设在外管的外侧,锁紧件可活动地设置在衬套上,且锁紧件具有可穿经外管的第一作用结构,第一作用结构能够顶压插设在外管中的内管,手柄设置在衬套上,手柄具有能够顶压锁紧件的第二作用结构,手柄具有第一工作状态和第二工作状态,当手柄处于第一工作状态时,第二作用结构顶压锁紧件,以使锁紧件的第一作用结构顶压内管,当手柄处于第二工作状态时,锁紧件在衬套上可活动。本发明的锁紧装置,采用顶压的方式对内管在外管中的位置进行锁止,能够提高锁止的强度,有助于减少因使用次数的增多,而导致零件磨损、内管松动的问题发生。
