Pushing part 102, between the bracket 1 and moving mass 101 be equipped with reset spring 103.Needing folding left connecting rod 2 and right company
When bar 3, moving mass 101 only need to be pressed, pushing part 102 is V-shaped, so the inner sidewall of pushing part 102 is inclined-plane, in pushing part
102 with 101 transverse movement of moving mass when, the inner sidewall of pushing part 102 just pushes left-hand rotation motion block 6 and right-hand rotation motion block 7 to rotate, thus
So that left engagement shaft 8 is skidded off out of left annular groove 4, right engagement shaft 9 is skidded off out of right annular groove 5,2 He of left connecting rod can be rotated at this time
Right connecting rod 3 and carry out folding, operation very it is convenient.
As shown in Figures 3 to 8, the block 6,7 that turns left and right passes through first rotating shaft 12 and the second shaft 13 and branch respectively
Frame 1 is rotatablely connected, and the holding spring 11 is the torsional spring being set in first rotating shaft 12 and the second shaft 13, the torsional spring
One end be resisted against on left-hand rotation motion block 6, the other end of the torsional spring is resisted against on right-hand rotation motion block 7, on the left-hand rotation motion block 6
Left support portion 14 equipped with the extension of motion block 7 of turning right, the right-hand rotation motion block 7 extend equipped with motion block 6 of turning left and can be with a left sides
Support portion 14 is against the right support portion 15 of cooperation.When pushing part 102 pushes left-hand rotation motion block 6 and right-hand rotation motion block 7 to rotate, torsional spring stress
It deforms, after left engagement shaft 8 is detached from left annular groove 4, right engagement shaft 9 is detached from right annular groove 5, removes to the application of moving mass 101
Thrust, torsional spring elastic recovery and push left-hand rotation motion block 6 and right-hand rotation motion block 7 to rotate, the left support portion 14 and right in this rotation process
Support portion 15 against and make left-hand rotation motion block 6 and right-hand rotation motion block 7 return to origin-location and keep.
As shown in Figure 6 and Figure 8, the left engagement shaft 8 is threaded through in the left through-hole 16 on left-hand rotation motion block 6, the right side
Engagement shaft 9 is threaded through in the right through-hole 17 on right-hand rotation motion block 7, and the left and right through-hole 16,17 sectional areas are greater than left and right engaging
Axis 8,9 cross-sectional areas and enable left engagement shaft 8 and right engagement shaft 9 movable in corresponding left through-hole 16 and right through-hole 17.Institute
With left engagement shaft 8, there are activity space, right engagement shaft 9, there are activity spaces in right through-hole 17 in left through-hole 16, therefore,
When left-hand rotation motion block 6 and right-hand rotation motion block 7 rotate and left engagement shaft 8 and right engagement shaft 9 are driven to skid off out of left annular groove 4 and right annular groove 5
Just than smoothly, being convenient for operation.
As depicted in figs. 1 and 2, the moving mass 101 is to be connected on bracket 1 elastic plate that can press deformation, institute
The pushing part 102 stated is arranged on elastic plate.
