Embodiment
The utility model is described in further detail below by specific examples of the implementation and with reference to accompanying drawing.
Join shown in Fig. 1 and Fig. 2, present embodiments provide a kind of sleeve arrangement, including sleeve body 11, set inside sleeve body 11
There is pars contractilis, one end of pars contractilis is stretched out outside sleeve body 11, and can be retracted under external force pressure in sleeve body 11.By with stretching
The pars contractilis top of contracting function is loosered a bolt by sleeve body rotation again after opening the driving head realization unblock of spring release screw bolt.
In the present embodiment, pars contractilis includes telescopic block 12 and spring 13, and spring 13 is in sleeve body 11, telescopic block 12
One end and spring 13 compress and connect, the other end is stretched out outside sleeve body 11, and the present embodiment is that telescopic block 12 provides by spring 13
Active force, to push up out the driving head of spring release screw bolt, then, by the way that the inwall of sleeve body 11 and spring release screw bolt 20 is mutual
Lock cooperation is unlocked.The present embodiment uses telescopic spring mechanism, unblock spring release screw bolt 20, is not only simple in structure, and
It is convenient to coordinate with spring release screw bolt 20, as shown in Figure 3.
In order to limit the flexible stroke of pars contractilis, sleeve body 11 is provided with position-limit mechanism, and position-limit mechanism is connected with pars contractilis, will
Pars contractilis is limited in optimal stroke range.
Specifically, the position-limit mechanism includes spacer pin 17, pin-and-hole 16 and spacing hole 15, and pin-and-hole 16 is located at the side of telescopic block 12
Wall, spacing hole 15 are located at the side wall of sleeve body 11, and spacer pin 17 is connected through spacing hole 15 with pin-and-hole 16, and spacer pin 17 can be along limit
Position hole 15 is axially moved, by the flexible travel limit of telescopic block 12 in spacing hole 15.
In order to cut down screw active force during sleeve suffered by spring 13 and reduction screw during produce noise, and
Absorb the fine difference of bolt length and provide enough supports and stiction when ensuring urgent, the pars contractilis can also be set
Buffer stopper 14, buffer stopper 14 are made of with the material of cushioning effect, as rubber or other flexible materials are made, buffer stopper 14
The side for axially facing toward spring 13 is set, and buffer stopper 14 is arranged to ledge structure, including base and is connected with the center of base
Cylindrical boss, spring 13 is placed in cylindrical boss.
In the present embodiment, telescopic block 12 has the opening for accommodating spring 13, spring axially towards one end of spring 13
13 one end is stretched into opening, and the other end of telescopic block 12 is provided with centre bore 18, and the diameter of centre bore 18 is less than cutting for spring 13
Face diameter and the diameter for being more than cylindrical boss so that telescopic block 12 can both be limited in spring 13 in opening, again can be in bullet
