The pin joint of frame articulated section 241 and second handle articulated section 212 substantially sight alignment when, push rod 23 by sliding block be pushed to farthest away from
The position of linkage.Due also to when linkage reaches dead-centre position, be delivered to from sliding block push rod 23 end power without
Method changes linkage, so as to which in the dead point opening position, device reaches stable state, and the reset force of spring will not be by connecting rod machine
Structure takes away dead-centre position.
The use of the word such as " on ", " under ", "left", "right" is only used for that phase is described with reference to the attached drawings it should be understood that in this patent
To position relationship, behind the absolute position for being described object or orientation change, then the relative bearing relation will correspondingly change.
Linkage 2 is fixed relative to base portion 6, and especially, the connecting rod rest 24 of linkage 2 is fixed on the base portion 6.
Preferably, the adjustable in length of the push rod 23.As shown in figure 5, push rod 23 may include two bar parts, two bars
Part is connected through a screw thread.The distance being screwed in by adjusting one of bar part in another bar part, it can adjust whole
The length of push rod.Or the regulation of push rod total length can be realized by the length for the one of bar part for changing push rod.
In addition, the length of push rod can be directed to the spring and part (such as floating rule) of specific dimensions and model and customize so that, working as connecting rod
When mechanism 2 is in dead point, the second end of spring just reaches at the spring mount point of part, need not grasp during so as to install spring
Make personnel deliberately to go to pay close attention to when spring is elongated appropriate level.
First fixed mechanism 4 is fixed relative to the base portion 6, the first end for fixed spring.
First fixed mechanism 4 has the first spring engagement member 7 and the first fixed mechanism mounting blocks 8, and described first is solid
Mechanism mounting blocks 8 are determined fixed to base portion 6 and are spaced apart with base 1.So, spring and need to pacify spring-loaded part and can place
In the lower section of the first fixed mechanism mounting blocks 8, the bar 71 of first spring engagement member passes through the first fixed mechanism mounting blocks
Through hole 81 is to engage the first end of spring.
Preferably, the first spring engagement member has knob, and first spring engagement member is screwed manually to facilitate.Described
The through hole 81 of the bar 71 of one spring engagement member and the first fixed mechanism mounting blocks is threadably engaged.Manually screw the first bullet
The knob of spring fastener, the height of bar 71 can be adjusted, in order to engage and depart from bar 71 with one end of spring.
Second fixed mechanism 5 is fixed relative to the sliding block, and for the second end of fixed spring.With shown in Fig. 1, when
When rotating counterclockwise handle 21, push rod 23 will be in sliding eye 242 to left, to promote sliding block to the left；When rotating clockwise
During handle 21, push rod 23 will translate to the right in sliding eye 242, with away from sliding block (now sliding block is motionless).
Second fixed mechanism 5 has the fixed mechanism mounting blocks 12 of second spring fastener 9 and second, and described second is solid
Mechanism mounting blocks 12 are determined fixed to sliding block 3 and are spaced apart with base 21.So, spring and need to pacify spring-loaded part and can put
Put and pass through the second fixed mechanism mounting blocks in the lower section of the first fixed mechanism mounting blocks 8, the bar 91 of the second spring fastener
Through hole 121 and engage the second end of spring.
Preferably, it is in stepped cylindrical head 92 that the second fixed mechanism mounting blocks 12, which have, i.e. head 92 has
There are larger-diameter first section and the second section of small diameter, so as to be bonded on the installation of the second fixed mechanism when head 92
When in the through hole 121 of block, larger-diameter first section is stuck in the top of through hole 121.
Described device also includes limited block 10, and it is fixed relative to the base portion 6.Limited block 10, which is used for limitation, to be needed to install
The position of the part of spring, so as to be advantageous to the alignment of the bar 91 of second spring fastener and the second end of spring.
When spring being installed into floating rule etc. by described device needing to pacify spring-loaded part, following steps can be carried out.
The first end of spring is fixed to the first spring mount point of part first, and part and spring are placed in first and consolidated
Determine the lower section of 4 and second fixed mechanism of mechanism 5, and cause part against limited block 10.Wherein, the first end of spring is fixed to zero
First spring mount point of part may include following situation：, can be directly by spring in the case where the first end of spring has hook
The corresponding position for being hooked in part at first end, or can be by additional connector by the first end and part of spring
The first spring mount point be connected.
Secondly, the first spring engagement member 7 of the first fixed mechanism 4 is rotated so that the bar 71 of the first spring engagement member passes through
The through hole 81 of first fixed mechanism mounting hole and the first end for compressing/engaging the part or spring.By the second fixed mechanism 5
Second spring fastener 9 passes through the through hole 121 of the second fixed mechanism installed part and the bar 91 of second spring fastener 9 is engaged
Second end of spring.
Then, the handle 21 of linkage 2 is manually rotated counterclockwise, the dead-centre position until reaching linkage 2.
When handle 21 rotates counterclockwise, as it was previously stated, push rod 23 will promote sliding block 3 to the left, and then drive the second fixed mechanism 5 to
Left movement, and the second fixed mechanism 5 will drive the second end of spring to left movement.The length of the push rod 23 of the present apparatus is arranged to make
, when reaching the dead point of linkage 2, spring has been elongated, reached the second spring mount point of part.So, it is now
Second end of spring manually can be connected to the second spring mount point of (such as by hook at the end of spring second) part.
When needing to dismantle spring from part, the part for being provided with spring is placed in the first fixed mechanism 4 and first
The lower section of two fixed mechanism 5, and cause part against limited block 10.Secondly, the first spring engagement member of the first fixed mechanism 4 is rotated
7 so that the bar 71 of the first spring engagement member through the first fixed mechanism mounting hole through hole 81 and compress/engage the part or
The first end of spring.The second spring fastener 9 of second fixed mechanism 5 is passed through to the through hole 121 of the second fixed mechanism installed part
And the bar 91 of second spring fastener 9 is caused to engage the second end of spring.Then, the manually end of contact spring second and floating rule
The connection of second spring mount point, and the handle 21 of linkage 2 is rotated clockwise, until spring is retracted to its original length.
Next, spring and part are removed from the present apparatus.
