Description
Technical field
The present invention relates to baton field, a kind of utilize lamp cylinder as the mechanical lock retractable spontoon of button.
Background technology
Baton is a kind of conventional police equipment.In general baton, its length is all fixing so that inconvenient to carry,
Then there has been telescopic baton.
Retractable spontoon is to be set-located by more piece fitting structure to form, and is pulled out by pipe fitting or throws away, regain during use
Time, need under plane, press pipe fitting press-in contraction baton head end.This structure for during Telescopic to be reused relatively
For wasting time and energy, and need when pressing down look for a smooth and hard plane and keep baton and the perpendicular shape of plane as far as possible
State, otherwise baton easily skids and bumps against user, and the most so uses force compresses baton, and intraware can be made to loosen deformation, pipe
Part is lost locking function and the most just can naturally be stretched out or regain, and makes baton lose efficacy.
Additionally, in existing retractable spontoon, perform task for the ease of night, all can be provided with illuminating lamp, but arrange
Illuminating lamp only only have illumination functions, can not realize the unblock of baton is shunk as unlocking button, to a certain extent can
Increase the volume of baton so that carry use inconvenience.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of and utilizes lamp cylinder as the mechanical lock retractable spontoon of button, its structure
Simply, shrink freely, sealed firm, and the contractile function function to baton can be realized with illuminating lamp.
For achieving the above object, the technical solution used in the present invention is: a kind of utilize lamp cylinder to stretch as the mechanical lock of button
Contracting baton, including the handle tube of hollow, middle-end pipe, top pipe, described stage casing pipe, top pipe are sequentially movably arranged in handle tube,
The most also including relieving mechanism, lamp jacket casing part, described middle-end pipe, the tail end of top pipe are respectively arranged with manages along middle-end pipe and top
The middle-end kayser of caliber lateral direction elastic extension, top kayser, the front end of described handle tube and the front end of middle-end pipe
Inside being provided with and middle-end kayser, the first draw-in groove that top kayser is corresponding, the second draw-in groove, described relieving mechanism includes for by middle-end
Kayser and top kayser respectively along the release lever shunk inside middle-end pipe and top pipe caliber and locating cover, by pulling, release lever
One end be fixed on locating cover one end, described be arranged on the other end of locating cover by spring by pulling, described release lever sets
Putting in handle tube and be fixedly installed on the tail end of handle tube by locating cover, described lamp jacket casing part includes hollow fixed cover, lamp
Cylinder, described lamp cylinder is movably arranged in hollow fixed cover, and the front end of hollow fixed cover is threaded connection with the tail end of handle tube, lamp
The tail end of cylinder offsets with by pulling, and the illuminating lamp of the lamp cylinder other end is spacing by the edge of hollow fixed cover tail end.
The beneficial effects of the present invention is:
1. the present invention extends middle-end kayser, top card by being provided with at the tail end of middle-end pipe, top pipe toward caliber outer elastic
Lock, and in the front end of the front end of handle tube and middle-end pipe, it is provided with the first draw-in groove, the second draw-in groove, top pipe and middle-end pipe draw
Be connected on the first draw-in groove, the second draw-in groove fixing after stretching by middle-end kayser, top kayser correspondence, good fixing effect, sealed surely
Gu；
2. by being provided with relieving mechanism at handle tube tail end, by masthead will be discharged to middle-end pipe by the effect of pulling in relieving mechanism
The middle-end kayser of tail end, makes middle-end kayser shrink inside handle tube caliber, can realize shrinking, middle-end after departing from the first draw-in groove
Pipe shrinks after driving top pipe to shrink toward handle tube, discharges masthead to the top kayser of top pipe tail end, make top kayser toward in
Shrink inside end pipe caliber, can realize after departing from the second draw-in groove shrinking, simple in construction, shrink freely, easy to use；
3. by being provided with lamp jacket casing part at handle tube tail end, wherein the tail end of lamp cylinder offsets with by pulling, and movable solid with hollow
In fixed set, and hollow fixed cover is threadedly attached in handle tube tail end, then by pressing lamp cylinder so that lamp cylinder tail end is given by pulling
