The specific embodiment

Referring to accompanying drawing 1-3, the utility model comprises flexible end, in the present embodiment, flexible end is made of three-joint pipe footpath sleeve pipe 1 gradually thin and mutual chimeric socket, the junction of adjacent casing is provided with flexible latching structure 2, flexible latching structure 2 radial expansions are connected in the sleeve pipe inner tubal wall so that the thinner sleeve pipe of caliber is fixed in the outer or withdrawal sleeve pipe of the thicker sleeve pipe of caliber, wherein, the sleeve pipe 11 that caliber is the thinnest is provided with one and rotates flexible drives structure 3, and drives structure 3 is flexible by the flexible latching structure 2 on connecting rod 4 its adjacent casings of control.

As shown in Figure 3, drives structure 3 comprises that an end is connected with connecting rod 4 to control the drive rod 31 of flexible latching structure 2, offer axial groove 311 on the drive rod 31, drive rod 31 overcoats one turnbarrel 32, offer the identical spiral groove of at least one rotation direction 321 on the turnbarrel 32, in the present embodiment, spiral groove 321 is two.Card post 33 extends radially out and is placed in two spiral grooves 321 from axial groove 311, thereby during turn turnbarrel 32, drive rod 31 is just blocked post 33 to be promoted and move down, and moves down to promote connecting rod 4.Turnbarrel 32 outer preferably sockets one are used to drive the outer sleeve 34 of its rotation, and outer sleeve 34 is provided with the groove of accepting the projection on the turnbarrel 32, so that turnbarrel 32 rotates with outer sleeve 34.

Referring to Fig. 3, flexible latching structure 2 comprises hollow base 21, be located in the pedestal 21 and Tapered Cup 22 and fastener holder 23 that an end axially stretches out on pedestal, hollow base 21 is bolted on the thinner sleeve pipe of caliber, Tapered Cup 22 is provided with the middle vacancy of pedestal, the one end links to each other with connecting rod 4, the other end is that tapering point 221 and tapering point axially stretch out from pedestal 21, tapering point 221 connections one have the elastic component of reset response when external force disappears, fastener holder 23 is fixedly arranged on the thicker sleeve pipe corresponding end of caliber, and it is socketed on outside the tapering point 221 simultaneously.Tapered Cup 22 moves down when connecting rod 4 promotes being subjected to, thereby the flexible fastener 24 that promotes on the fastener holder 23 stretches out, and to block the inner tubal wall than extra heavy pipe, so just makes to have good stability when stretching out than tubule; When need not to use, rotating jacket tube 34 is to cancel the compression of 31 pairs of connecting rods 4 of drive rod, and Tapered Cup 22 just resets under the elastic-restoring force effect, thereby flexible fastener 24 is withdrawn in the fastener holder 23, so just, can make things convenient for the use of baton greatly with being withdrawn into than tubule than in the extra heavy pipe.

In the present embodiment, flexible fastener 24 be a prill, offers the through hole that is used to place prill on the fastener holder 23, the best and prill of the size of through hole big or small similar.

For making the utility model can be withdrawn into the shortest length, the sleeve pipe 12 that caliber is the thickest in the flexible end is for holding end.

As shown in Figure 4, in order further to strengthen the practicality of baton of the present utility model, improve its security protection performance, hold end 12 outer surfaces and be provided with evagination guard member 5, guard member 5 comprises fixture 51 and revolving part 52, fixture 51 is fixedly arranged on to be held on the end 12, revolving part 52 is socketed on that to hold end 12 outer and can thornyly hold end 12 and rotate, and its chimb 521 built-in resilient clamp member 522 hold that correspondence is provided with two above draw-in grooves 121 on the end 12, when resilient clamp member 522 in draw-in groove 121 relatively the time, driven by elastic force and snap in the draw-in groove 121, revolving part 52 and fixture 51 are separated and form certain angle, for example, intersect vertically, thereby have better protective capacities.When need not to use, turn revolving part 52 gets final product up to overlapping up and down with fixture 51, takies littler space after folding, so that carry.
