Hold-down bolt 106 is provided with, the through hole at the described middle part of locating dowel 102 of connection, institute are provided with described operating desk 101
The end for the hold-down bolt 106 stated is through described through hole 103 and stretches out below described through hole, in described hold-down bolt
106 ends are provided with locking nut 107, and the spring 108 being coaxial therewith is provided with the described inner side of locating dowel 102, described
The lower end of spring 108 is against on the described upper surface of operating desk 101, and the described upper end of spring 108 can be against described depression bar 104
On lower surface.In the utility model, gonnecting rod body stub end and small head end are respectively placed in two locating dowels, make two locating dowels
External diameter be respectively greater than corresponding stub end and small head end circular hole internal diameter, make gonnecting rod body hanging with respect to operating desk, make major part
End and small head end circular hole and locating dowel it is coaxial, now by depression bar run through gonnecting rod body on circular hole and be plugged on locating dowel inner side,
By through hole of the hold-down bolt on the depression bar and it is plugged into below operating desk, now locking nut is tightened on hold-down bolt,
During persistently locking nut is screwed, hold-down bolt moves to side below operating desk, drives depression bar to locating dowel middle part
It is mobile, make depression bar lower surface extrusion spring, make spring-compressed, when gland is pressed on the circular hole upper surface of gonnecting rod body.
The utility model fixes gonnecting rod body stub end and small head end by being provided with the depression bar of gland, makes gonnecting rod body relatively solid
It is fixed, during being installed, the depression bar in two locating dowels can be made to limit the movement in the horizontal direction of gonnecting rod body, together
Shi Liyong glands limit the movement in gonnecting rod body vertical direction, can make gonnecting rod body when being drilled to gonnecting rod body or tapping
Keep stable, the quality of the company's of being favorably improved drilling or tapping.
After drilling or tapping processing is completed, locking nut is unscrewed, under the resilient force of spring, enables depression bar
Moved to away from operating desk direction, can now facilitate and remove depression bar from gonnecting rod body both ends, facilitate the dismounting of gonnecting rod body.
In the utility model, for convenience to being supported in the middle part of gonnecting rod body, it is preferable that in the locating dowel 102 described in 2
Between be provided with leg 112, the upper surface of described leg 112 and the upper surface of described locating dowel 102 are contour.
Embodiment 1：
In the present embodiment, in order that gland can preferably be fitted in the circular hole upper end of gonnecting rod body, it is preferable that described pressure
The side wall of lid 105 is that inclined-plane forms it into inverted V-shaped structure, the slope on described inclined-plane and the chamfering slope one of gonnecting rod body both ends circular hole
Cause.During locking nut is screwed, hold-down bolt moves to locating dowel direction, now, the gland on depression bar is pressed
Close above the circular hole of gonnecting rod body end face, due to being generally provided with chamfering on circular hole, make in the inclined-plane and circular hole on gland
Chamfering cooperates, and while the gland is pressed together on above circular hole, can be more convenient to reduce the external diameter of capping rim, make pressure
Lid is smaller with gonnecting rod body upper surface overlapping area, and the gonnecting rod body upper end area for enabling gland to cover is smaller, and then can be more
It is convenient that Drilling operation is carried out to gonnecting rod body.
Embodiment 2：
In order to avoid during locking nut is unscrewed, spring promotes depression bar to be moved upward formula, and depression bar is in elasticity
Removed under power effect on the inside of locating dowel rapidly, in the present embodiment, screwed hole be provided with the described side wall of locating dowel 102,
Caging bolt 110 is provided with described screwed hole, groove annular in shape is provided with the described bottom side of the wall of depression bar 104
109, the caging bolt 110 described in when the described lower end of depression bar 104 is plugged on described 102 inner side of locating dowel can be plugged on institute
In the groove 109 stated.In the present embodiment, side wall of the groove along depression bar is set to be set in circumferential ring-type.
When mounted, make locking nut that hold-down bolt is fixed on operating desk, caging bolt is screwed in locating dowel
Inner side, caging bolt is pressed together on the inside of groove, when needing to disassemble on gland, locking nut is unscrewed, now spacing
In the presence of bolt, prevent depression bar from side upsprings rapidly upward under the force of a spring, and then can facilitate and it is controlled
System, slowly screws out caging bolt out of groove, can conveniently control the movement of depression bar.
It is further preferred that in the present embodiment, the width of described groove 109 is more than the described end of caging bolt 110
External diameter, installing plate 111 is provided with described operating desk 101, described caging bolt 110 is away from described locating dowel
102 threaded one ends are connected on described installing plate 111.When hold-down bolt is removed from operating desk, make depression bar in spring
In the presence of, it can move up, due to the limitation of caging bolt, prevent depression bar from being removed from locating dowel rapidly, meanwhile, this
When under the action of the spring, the gland above depression bar can depart from gonnecting rod body upper surface, make gonnecting rod body produce loosening, continue to screw out
During caging bolt, you can disassemble gonnecting rod body.
Above-described is only embodiment of the present utility model, and the general knowledge such as known concrete structure and characteristic is herein in scheme
