[specific embodiment]

The utility model is a kind of improvement structure of handle square bar, it includes two square bars 1 and they is connected same the central axis 2 on the axis, can relatively rotate between these two square bars 1, described central axis 2 is provided with the position limiting structure 3 that can prevent that square bar from sliding on this central axis 2; Be respectively arranged with the clamping structure 5 that can prevent that them from extracting from 41 two, square bar hole on the lock body 4 on described two square bars 1, the thickness of distance between the nearest two ends of the clamping structure 5 of this two square bar 1 when two shift forks 42 on the lock body 4 stack is corresponding, normally get final product than thickness is slightly bigger, after like this utility model being assembled into the square bar hole 41 of lock body 4, two clamping structures 5 just are distributed in the both sides of lock body (as Fig. 5, shown in 6), making it can not gently anticipate to be pulled out with handle comes, so of the present utility model rational in infrastructure, and improved the theftproof performance of whole lock simultaneously.In addition, component that the utility model is required and material are all less, bring that it is simple in structure, easy for installation, cost of production is low.

In the preferred embodiment shown in Fig. 1-4, the clamping structure 5 that is arranged on the square bar wherein is direct stamping forming boss 6 on this square bar limit, and boss has 4 usually, and they are distributed in respectively on the four edges of square bar; The clamping structure 5 that is arranged on another square bar is the shell fragment 7 of fixed installation (adopting riveted way at this) on this square bar breach 11, and the perk part 71 of this shell fragment 7 is towards this boss 6 and exceed this breach 11.When reality was used, clamping structure can play the theftproof that improves whole lock.When taking out the utility model, the perk part 71 of shell fragment 7 is pressed in the square bar breach 11, just can transfers to smoothly from opposite side, thus of the present utility model easy to assembly, structure is firm.

As shown in Figure 4, at this moment, described central axis 2 and a square bar wherein are integrally formed as main square bar 12, another square bar is a time square bar 13, this moment, position limiting structure 3 had one, and be arranged on the central axis 2 of time 13 suits of square bar, the end at inferior square bar 13 is provided with axis hole 131 usually, and inferior square bar 13 is enclosed within on the central axis 2 by the axis hole in it 131.This position limiting structure 3 includes the limiting section that is arranged on this time square bar 13 132 and is arranged on this central axis 2 and the annular groove 21 corresponding with this limiting section 132, and limiting section 132 rotates in the track of annular groove 21.In the present embodiment, limiting section 132 is by the salient point of inferior square bar 13 toward these annular groove 21 direction drawings.

Certainly, also can other structure, for example on two square bars, have axis hole 131, be sleeved on the two ends of central axis 2 then by axis hole 131 separately, this moment, position limiting structure 3 will have two, each position limiting structure 3 include the limiting section that is arranged on the square bar 1 132 and be arranged on the central axis 2 and with these limiting section 132 corresponding annular grooves 21, same, each limiting section 132 all rotates in the circuit orbit of its pairing annular groove 21; Limiting section 132 also can adopt by the salient point of square bar 1 toward these annular groove 21 direction drawings.

The utility model is suitable for needing to install on the lock body of inside and outside handle.
