There is perpendicular support arm, perpendicular support arm can protrude into downwards the perpendicular support arm periphery on pedestal in corresponding hole, below pallet and be equipped with protection knife rest use
Gum cover is fixed on the base in corresponding fixation hole by gum cover.Existing counter balance is before use, need two pallets
Following protective glue set is removed, could normal use.In order to protect the edge of a knife after use, avoid the edge of a knife in running order,
Also gum cover is reinstalled, can just enter cabinet placement in this way, this mode installing and dismounting gum cover is time-consuming and laborious, and gum cover also holds
Easy to be lost or damage, causes counter balance is in running order to be placed, is easily damaged the edge of a knife, the accuracy of counter balance is big
It is big to reduce, it can also seriously affect the effect of teaching experiment.
Summary of the invention:
The purpose of the present invention aims to solve the problem that problem of the existing technology, provides one kind and can effectively protect knife when placing
Mouthful, the counter balance that the middle school teaching for avoiding the edge of a knife from damaging uses.
The present invention relates to a kind of counter balances that middle school teaching uses, including pedestal, intermediate slide, the lever with scale and support
Disk, the pallet are mounted on the both ends of lever by the hanger, and hanger lower end, which is equipped with, erects support arm, on the upper surface of the pedestal
Jack is formed, the lower end of the perpendicular support arm is protruded into the jack, and the bottom for erecting support arm is equipped with the first magnet, is set below jack
Have the turntable being plugged and fixed on fulcrum, form several double wedges on the outer circle side wall of the turntable, on several double wedges between
Every being equipped with the second magnet and third magnet, one end of second magnet and the first magnet is heteropolar, the third magnet and the
One end of one magnet is homopolarity, and the bottom of jack forms through-hole, and the second magnet is plugged in the through-hole, and through-hole side is inserted
Hole bottom forms the link slot communicated with turntable, and limit plate is plugged in the link slot, and limit plate upper sleeve has spring, institute
The both ends for stating spring are separately fixed on the inner wall and limit plate of link slot, when the first magnet and attracting the second magnet, erect branch
Arm is pressed against on limit plate and the lower end holding of limit plate is on turntable between two neighboring double wedge, and spring is become by compression at this time
Shape；
External screw thread is formed on the outer wall of the perpendicular support arm, perpendicular support arm upper sleeve, which is bolted with, to be pressed against on pedestal upper surface
