The lower outside of slide bar is fixedly connected with perpendicular shaft, and the shaft is arranged in slotted hole and can be along oval hole length
It slides in direction；The lower end of slide bar is fixedly connected with briquetting；
First through hole of the front-rear direction through setting is provided in the middle part of the guide sleeve, the top of the slide bar is grown along it
Degree direction is provided with multiple equally distributed second through-holes, and the second through-hole is adapted with first through hole, and is connected by axis pin.
The present invention is slidably matched by the shaft on the slotted hole and slide bar in the middle part of compression bar, can utilize lever principle into
The adjustment of row slide bar displacement in longitudinal space waits for preloading spring so as to make briquetting longitudinally act on, and second on slide bar is logical
First through hole on hole and guide sleeve can carry out the locking of pre-stressed position by axis pin cooperation, to which the device can be convenient for one
Worker carries out the assembling operation of gear pump relief valve.The apparatus structure is simple and convenient to operate, easy to spread.
Further, in order to avoid the loss of axis pin, the upper end of the supporting rod is fixedly connected in the side away from guide sleeve
There are the first link, the upper end of the axis pin to be fixedly connected with the second link, connect by rope between the first link and the second link
It connects.
Further, in order to be more convenient to operate, the compression bar is telescopic rod.
Further, for the ease of the alignment of first through hole and the second through-hole, the cross section of the slide bar is rectangular, described to lead
It is rectangle compatible with the slide bar to the endoporus of set.
