The specific embodiment

Below in conjunction with accompanying drawing the present invention is described further:

Extremely shown in Figure 5 by Fig. 1; The embodiment of a kind of tapered end of the present invention; Include outer tube 1, be provided with the lock core 5 with outer tube 1 coaxial setting outside in the sleeve pipe 1, sleeve pipe 1 radially is provided with lockhole 11 outside; Be provided with spring 8 in the lockhole 11 and send son 7; The front end of described lock core 5 is provided with rotating disk 3, is provided with the syndeton of rotating synchronously again after the two is rotated to an angle relatively between an end of rotating disk 3 and the rotating shaft 51 of lock core 5, is provided with stop sheet 21 at rotating disk 3 other ends; Between rotating disk 3 and lock core 5, also be provided with and order about the torsion spring 4 of rotating disk 3, describedly send son 7 to have to move down with overcoming spring 8 active forces and separate the second place that stop sheet 21 is rotated to locking direction with stop sheet 21 to the primary importance of locking direction rotation to stop stop sheet 21 with stop sheet 21 clamping matching to locking direction rotation.Even the lock among the present invention is in opening; Stop sheet 21 is blocked the active force that makes rotating disk 3 overcome torsion spring 4 can not rotate owing to send son 7 to move (promptly being in primary importance) under the resetting of spring 8; Can lock core rotating shaft 51 be rotated to lock-out state with key 6 like this, that is to say, make when lock core rotating shaft 51 is in the lock state because lock core changes 51 syndetons specific with rotating disk 3; Stop sheet 21 still is in lockset position of coupler, so just can take off key 6.When inserting, locking bar 9 will send son 7 to press down (sending son 7 to be in the second place) in the lockhole 11; Send son 7 no longer to block stop sheet 21; Under the active force of torsion spring 4; Rotating disk 3 drives stop sheets 21 and rotates to latched position and promptly can insert in the locked groove 91 of locking bar 9 and realize that no key automatically locks, thereby has improved the convenience of use.

Above the specific syndeton of said lock core rotating shaft 51 and rotating disk 3; Specific to structure, a lot of modes are arranged, such as adopting like Fig. 1, the structure shown in 2; Promptly on the end face axle center of rotating shaft 51, be provided with flat side's boss 511; On the end face of rotating disk 3, be provided with the shrinkage pool 31 coaxial with rotating disk, the circumferential wall of shrinkage pool 31 is provided with axisymmetric two spacing protuberances 311, and the flat side's boss 511 in the rotating shaft 51 is inserted in the described syndeton of shrinkage pool 31 interior formations of rotating disk 3.Can certainly in rotating shaft, establish the projection of 1/4 circle; On rotating disk, establishing semicircle orifice or 3/4 circular hole (difference according to the two relative rotation angle is provided with) then realizes connecting; Through in rotating shaft, establishing radial peg, establish radially annular groove on the rotating disk, realize connecting by radial peg and annular groove radially; Perhaps also can stretch out one or two eccentric projection at the end face of rotating shaft, realize connecting and establish non-full circle annular groove at the end face of rotating disk; And the various ways of much no longer giving an example in addition.But adopt illustrated structure, the one, bonding strength is better, and the 2nd, structure is also simpler relatively, is to be preferred mode therefore.
