This tapered end 40, comprise a locking bolt 41 that is positioned at these tapered end 40 ends, one lock housing 42, one spring 47 and an elastic block piece 48, this tapered end 40 is located in via this ccontaining opening 32 in this ccontaining tube 30, and select that inserting pulls and be fixed in wherein one should insert in the hole 282 of pulling with this locking bolt 41, and the side of this tapered end 40 is coated by these ccontaining tube 30 sealings fully, the wall of this lock housing 42 offers a cinclides 421, have a limiting stopper 43 and an eccentric shaft 422 in this lock housing 42, these limiting stopper 43 1 ends are established a retracing spring 44, this retracing spring 44 is resisted against the inwall of this lock housing 42, these limiting stopper 43 other ends then are arranged in the cinclides 421 of this lock housing 42, the rotation in this lock housing 42 freely of this eccentric shaft 422, and abut against a start groove 431 in this limiting stopper 43, driving this limiting stopper 43 during these eccentric shaft 422 rotations protrudes or this cinclides 421 that submerges, each member in the aforementioned lock housing 42 is technique known, so no longer describe in detail, when this limiting stopper 43 protrudes this cinclides 421, be slidedly arranged in this long groove 33, this tapered end 40 sets firmly a block bolt 45, this block bolt 45 is slidedly arranged in this weak point groove 34, make this tapered end 40 be slidedly arranged in this ccontaining tube 30, and be subjected to the restriction of this block bolt 45 and can be from should be ccontaining coming off in tins 30, this block bolt 45 can be located on this locking bolt 41, and the length of this block bolt 45 is long than the maximum gauge of this locking bolt 41, also than the interior path length of this lock housing 42, the bottom of this locking bolt 41 is located in this lock housing 42, and it is fixing with this lock housing 42 with a hosel 46, these spring 47 1 ends are sheathed on this locking bolt 41, the other end abuts against in through hole 31 peripheries of this ccontaining tube 30, this elastic block piece 48 is positioned at 47 on this through hole 31 and this spring, and be sheathed on this locking bolt 41, this elastic block piece 48 1 end moulding one location protuberance 481, this positioning convex portion 481 is placed in wherein in this circular rabbet 283, offer a perforation 482 in the middle of this positioning convex portion 481, this locking bolt 41 is arranged in this perforation 482.

The above is the utility model embodiment primary member and configuration explanation thereof.Occupation mode and effect as for the utility model embodiment, seeing also Fig. 5 cooperates shown in Figure 3, the utility model contains the button pincers with the second arm body 26 of the first arm body 21 of this fixing clamp arm 20 and this activity jig arm 25 and places on the tire of vehicle when using, this locking bolt 41 is optionally inserted to pull to be fixed in wherein and one should be inserted in the hole 282 of pulling, so that between this fixing clamp arm 20 and this activity jig arm 25 apart from amplifying or dwindling, can arrange by this on the tire that applies to different sizes, Duan Ze reaches antitheft purpose by this in order to hinder tire rolling after this fixing clamp arm 20 and this activity jig arm 25; In addition, because that this hollow transverse tube 23 and this cross bar 28 are is non-circular, and the setting of auxiliary transverse tube 22 and auxiliary cross bar 27 is arranged in addition, make this activity jig arm 25 be difficult to respect to 20 rotations of this fixing clamp arm the ability of reinforced tire lock twisting resistance.

Function mode as for the utility model tapered end 40, see also shown in Fig. 6-9, wherein, Fig. 6 and Fig. 7 locking bolt 41 inserted and pulled in a cutaway view when inserting in the hole 282 of pulling wherein, and as shown in FIG., this tapered end 40 of user is toward the direction propelling movement of these hollow transverse tubes 23, this locking bolt 41 is inserted pulled in wherein one inserting in the hole 282 of pulling, this moment, this spring 47 was accumulated the elasticity potential energy, but was positioned at this long groove 33 because this limiting stopper 43 protrudes this lock housing 42, made this locking bolt 41 to be separated from and inserted the hole 282 of pulling

See also Fig. 8 and shown in Figure 9, this inserts the cutaway view when pulling hole 282 for locking bolt 41 leaves, when user's release, by this eccentric shaft 422 of rotation, because this eccentric shaft 422 is located in the start groove 431 of this limiting stopper 43, so can drive this limiting stopper 43 in this cinclides 421 submerges this lock housing 42, the elasticity potential energy that this moment, this spring 47 was accumulated is released this tapered end 40, but but be confined in this weak point groove 34 because of this block bolt 45 that is fixedly arranged on this tapered end 40, make this tapered end 40 still be restricted and can not break away from this ccontaining tube 30, this moment, this cross bar 28 can freely slide in this hollow transverse tube 23, and these elastic block piece 48 meeting of short duration location in circular rabbet 283 make things convenient for the user to push this tapered end 40; This limiting stopper 43 submerges after this lock housing 42, be subjected to the inwall compressing of this ccontaining tube and can't protrude this

cinclides

421, and 44 of this retracing springs are accumulated the elasticity potential energy simultaneously, after treating that the user pushes this tapered end 40 toward the direction of this hollow transverse tube 23, this retracing spring 44 can push away this limiting stopper 43 in this long groove 33.

The side of tapered end 40 of the present utility model is coated by ccontaining tube 30 sealings fully, that is locking bolt 41 and the hosel 46 of tapered end 40 can't be touched from the outside, so can prevent effectively that intentionally the personage destroys tapered end 40.

More than by specific embodiment the utility model is had been described in detail, formation is to restriction of the present utility model but these are not.Under the situation that does not break away from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection domain of the present utility model.
