Be used to install the special-purpose tool for assembling of above-mentioned roll guard, comprise that one is used to stretch into the body of rod in the hollow montant of fence, its described body of rod is plugged in the inner rotating interior body of rod of the outer body of rod by a hollow outer body of rod and and forms, one end of the described interior body of rod is provided with at least one and is used to back down the ledge that the montant sidewall makes formation projection on the montant sidewall, the side of described ledge also is provided with the cutting edge of projection, the rotation handle of the body of rod in the other end of the body of rod is provided with and is used to rotate in described, the described outer body of rod one end are that the cube and the described cube that play fixing outer body of rod effect after being used to insert in the fence are provided with the opening that is used to expose interior body of rod ledge.
Above-mentioned a kind of roll guard and special-purpose tool for assembling thereof, it also is provided with one outside on body of rod and is used to adjust the backstay that the body of rod stretches into position in the hollow montant of fence, described backstay be provided with the location set screw by one and can be connected to along the anchor clamps that outer body of rod axis direction moves outside on the body of rod.
Technique effect of the present utility model is: can back down the fence erecting tools that the montant sidewall forms positioning convex by being provided with, make the fence no longer need be when producing by the manual punching press that hole is installed of workman, not only saved the production time, simultaneously also created advantage for machine production in enormous quantities, and when assembling, plug connector need not be installed, simplify installation procedure, make things convenient for the operation of installation personnel, improve installation effectiveness, and can guarantee the steadiness of installation.
The utility model is described in further detail below in conjunction with accompanying drawing.
