Screens 10 combines locking, and the trigger unit 32 driving under the sliding tooth 110 force makes the rebound of angle-regulating block 3 multiple
Position, the dovetail groove 33 include front portion 330, inclined portion 331 and afterbody 332, described anterior 330 with the junction of the inclined portion 331
Inwardly narrowed turning is formed, the inclined portion 331 and the junction of the afterbody 332 form outwardly turning, the swallow
The cell wall of stern notch 33 is equipped with from described anterior 330 guide grooves 333 for extending to the afterbody 332, as shown in Figure 5.
The reset spring part 4 includes the telescopic pin 42 at middle 41 both ends of housing 41 and housing, is equipped with the housing 41
Spring 43, the both ends of spring 43 are connected with the telescopic pin 42, telescopic pin 42 is remained out the state of pop-up.The telescopic pin
42 end falls into the guide groove 333 and offsets with it, when moving the angle-regulating block 3 reset spring part 4 relative to
The cell wall sliding of the dovetail groove 33, i.e., described telescopic pin 42 slide relative to the guide groove 333.
The fixing groove at the fixed middle part of reset spring part 4 is equipped among the articulated joint 20, the fixing groove is convex by two
Platform 24 forms；The angle-regulating block 3 is located in the fixing groove, the both sides of articulated joint 20 be equipped with to angle-regulating block 3 into
The spacing set screw 25 of row, the set screw 25 and 3 clearance fit of angle-regulating block, enable angle-regulating block 3
Slided but without departing from articulated joint 20.
The both sides of the lock part 31 are equipped with outwardly extending extension 30, in use, it is diagonal to pinch the extension 30
Spend adjusting block 3 and carry out pull, when angle-regulating block 3 resets, the extension 30 offsets with the articulated joint 20.
In the articulated joint 20 and axis hole 21,12 is equipped with angle retaining structure 1, the articulated joint 20 passes through connecting shaft
22 is hinged with the angle retaining structure 1 through the axis hole 21,12, and the connecting shaft 22 is by screwing in 22 end of connecting shaft
Screw 23 is fixed.Gasket 13 is equipped between the axis hole 12 of the axis hole 21 of the articulated joint 20 and the angle retaining structure 1, is reduced
The situation that articulated joint 20 is worn during rotational support foot 2.
When the utility model is used, angle-regulating block 3 described in the 30 outside pull of extension, the reset spring part are pinched
4 Relative slidings are to the front portion 330 of the dovetail groove 33, and the telescopic pin 42 falls into clamping in guide groove 333 herein, at this time institute
Stating lock part 31, to depart from the screens 10 in the unlocked state, can pass through rotational support foot 2 and carry out angular adjustment.In the angle
When adjusting block 3 and the support feet 2 synchronously rotate counterclockwise lift to the sliding tooth 110 and touch the trigger unit 32, such as
Shown in Fig. 2, continue upper lift and promote it to move inward the trigger unit 32 force by sliding tooth 110, so that the angle

Front portion 330 and inclined portion 331 between turning in guide groove 333, the telescopic pin 42 at both ends is in the trend flexed outward, makes multiple
Position bullet part 4 departs from the holding of front portion 330 of dovetail groove 33 from the state of rearwardly 332 Relative slidings of inclined portion 331, assigns the angle
The inside reseting elasticity of adjusting block 3 one, makes 31 and first screens 101 of lock part be adjacent to locking, support feet 2 is in angle maximum
Gear, as shown in Figure 3.When carrying out gearshift adjusting again, it only need to hold support feet 2 and rotate clockwise, in the reseting elasticity
Under the action of, the support feet 2 makes the lock part 31 jump into the second screens 102 from the first screens 101 to combine and lock automatically,
As shown in figure 4, same mode, support feet 2 can be rotated further adjust lock part 31 to the 3rd screens 103 and combined locking,
At this time, the angle-regulating block 3 resets completely, and the telescopic pin 42 falls into inclined portion 331 and 332 corner of afterbody of dovetail groove 33
Guide groove 333 in, prevent angle-regulating block 3 further in it is sliding, as shown in Figure 6 and Figure 7.
When manually resetting lock mode, same first outwards angle-regulating block 3 described in pull unlocks, then in angle tune
When locking nub 3 turns to suitable position, Manual press angle-regulating block 3, makes lock part 31 fall into the screens 10, gearshift
When, need again first outwards angle-regulating block 3 described in pull to unlock, repeat above-mentioned steps.
The utility model makes the locking by angle-regulating block 3, reset spring part 4 and the cooperation of the structure of articulated joint 20
Portion 31 can jump into locking in connection in different screens 10 successively by rotating, and realize the automatic adjustment lock of different stalls
It is fixed, without pushing and pulling repeatedly, very easy, fast power-saving is operated, and reduce the service life that push-and-pull number extends product；At the same time
Also the function of hand-reset locking, two kinds of operator schemes are remained, user can flexibly select.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Same, approximation or the technology deduction made based on this, replacement, improvement etc., are regarded as the protection domain of this patent.
