Abstract

A balance swing angle tester of a chain saw relates to a chain saw testing device, which solves the problems that the test accuracy can be influenced by errors produced by marking a reference line and that the reference line mark needs be marked twice for the test, which are produced while measuring the balance swing angle of a chain saw by using an angle ruler. Two connection rods are respectively arranged in the upper grooves on both ends of a balance arm at upper ends thereof, two hinged spindles are respectively arranged in a spindle hole and a first arrangement hole on both ends of the upper balance arm, two connection arms are respectively arranged in the lower grooves on both ends of a lower balance arm at lower ends thereof, another two hinged spindles are respectively in a spindle hole and a second arrangement hole on both ends of the lower balance arm, the lower cover of the lower balance arm is fixed below the upper cover of the lower balance arm, the upper balance arm and a fillet meter are fixedly connected with the spindles, and a pointer and a cantilever are movably connected with the spindles. The invention can instantly measure the balance swing angle just after the chain saw is lifted without scoring mark line, thus improving the test accuracy by over one time in comparison with the prior method.

Description

technical field [0001] The invention relates to a chain saw testing device. Background technique [0002] At present, there is no test device specially used to test the balance of chainsaws. The test for the balance performance of chainsaws is to first draw a marking line, and then use an angle ruler to measure the balance angle to determine the balance swing angle of the chainsaw. The shortcomings and shortcomings of this method are: the error generated when marking the reference line affects the test accuracy, and it is necessary to mark the test reference line at least twice during the test, which is time-consuming. Contents of the invention [0003] The purpose of the present invention is to provide a chainsaw balance angle tester to solve the problem that the error caused by marking the reference line affects the test accuracy and the test needs to test the reference line mark twice when measuring the balance swing angle of the chain saw with an angle ruler. [0004]...
