The opening of slot runs through the side wall of mounting base 110, and opposite with installation through-hole.Connection screw thread hole is set to the bottom wall of holding tank.Connection
When baffle 510 is connect with the first rocking bar 100, the protrusion 511 of baffle 510 is connected in holding tank, the side wall of protrusion 511 with
The side wall of holding tank abuts, and baffle 510 is fixed in holding tank by connection bolt 521.Holding tank is set in mounting base 110,
When connecting baffle 510 and mounting base 110, holding tank plays position-limiting action to baffle 510, makes first on protrusion 511 to connect
Through-hole and the connection screw thread hole in mounting base 110 are opposite one by one, and connection bolt 521 is facilitated to connect baffle 510 and mounting base 110；
In addition, the side wall of mounting groove cooperates with bolt 521 is connect, position-limiting action is played to pin shaft 300 by baffle 510, it is preferably anti-
Shotpin axis 300 is rotated around the axis of pin shaft 300.
Further, the second latch assembly 600 includes locking bolt 610, locking bolt 610 and pin shaft 300 close to the
The end of two rocking bars 200 connects.
The end close to the first rocking bar 100 of pin shaft 300 is equipped with the first locking through hole, the axis direction of the first locking through hole
It is identical as the radial line direction of pin shaft 300.As an implementation, the first locking through hole is threaded hole, locking bolt 610 and the
One locking through hole is threadedly engaged, and is abutted with the right side shown in Fig. 2 of the second rocking bar 200.As another embodiment,
One locking through hole is unthreaded hole, and locking bolt 610 passes through the first locking through hole and lock-nut 611 cooperates, further, locking spiral shell
The quantity of mother 611 is two, and two locking nut cooperations prevent to loosen, and improves the stability of connection.Locking bolt 610 with
The cooperation of first latch assembly 500 prevents pin shaft 300 along the axial movement of pin shaft 300, and the first latch assembly 500 prevents pin shaft 300
Axis around pin shaft 300 rotates, the movement of the first latch assembly 500 and the cooperation limitation pin shaft 300 of locking bolt 610, to subtract
Few abrasion of the pin shaft 300 to locking bolt 610.
Further, the second latch assembly 600 includes retaining ring 620, and retaining ring 620 is sheathed on pin shaft 300, and with the second rocking bar
200 abut, and locking bolt 610 is connect with retaining ring 620 and pin shaft 300 respectively.
Retaining ring 620 is cylindrical, and the internal diameter of retaining ring 620 is slightly larger than the diameter of pin shaft 300, and the outer diameter of retaining ring 620 is greater than the
The diameter of installation through-hole on two rocking bars 200.The periphery of retaining ring 620 is equipped with the second locking through hole, the second locking through hole edge
The periphery wall for extending radially through retaining ring 620 of retaining ring 620.As an implementation, the first locking through hole and the second locking through hole
It is threaded hole, locking bolt 610 is threadedly engaged with the first locking through hole and the second locking through hole respectively.Implement as another kind
Mode, the first locking through hole and the second locking through hole are unthreaded hole, and connection bolt 521 passes through retaining ring 620 and pin shaft 300 and two
Lock-nut 611 cooperates.When retaining ring 620 is connect with pin shaft 300, the left side shown in Fig. 2 of retaining ring 620 and the second rocking bar 200
Right side abut, position-limiting action is played to the second rocking bar 200 by retaining ring 620, increases the contact surface with the second rocking bar 200
Product reduces the abrasion to the second rocking bar 200.
Because preventing pin shaft 300 from rotating around the axis of pin shaft 300 by the first latch assembly 500, therefore, retaining ring 620 and the
Two rocking bars 200 may be configured as separate structure.When retaining ring 620 is installed, retaining ring 620 can be made relative to the second rocking bar 200 around pin shaft
300 axis rotation, facilitate adjust the first locking through hole and the second locking through hole it is coaxial and install locking bolt 610, thus just
Just the installation and removal of pin shaft 300.
As another embodiment, retaining ring 620 is fixed on the second rocking bar 200, and the outer peripheral surface of retaining ring 620 is equipped with kidney-shaped
The length direction in hole, kidney slot is arranged along the circumferential direction of retaining ring 620.
Retaining ring 620 is fixed on the end face away from connector of the second rocking bar 200 by welding.Kidney slot is through gear
The periphery wall of circle 620, the central axis of kidney slot and the centerline parallel perpendicular to 300 axis of pin shaft of protrusion 511, pin shaft
After 300 are connected in mounting base 110, the kidney slot being circumferentially arranged along retaining ring 620 increases the probability opposite with the first locking hole, from
And locking bolt 610 is facilitated to pass through kidney slot and the first locking hole.
