Background
The inertia mechanism is assembled by an inertia spring, an inertia pin, a power connection sleeve and a screw plug, and is a common firing mode of the firearm. When the inertia spring is released in the action process of the firearm, under the action of the elastic potential energy of the inertia spring, the inertia rod rushes forward to be communicated with the circuit, so that the firearm is ignited. Therefore, the load value of the inertia mechanism needs to be ensured within a certain range in the testing process of the product, and the action reliability of the firearm can be ensured. However, in the product testing process, a tester holds the load rod with a hand to load the inertia mechanism, so that the operation of the tester is inconvenient, and whether the load value tested by the inertia mechanism is accurate or not is influenced, the qualification of the tested product cannot be effectively guaranteed, and uncertain factors are brought to subsequent use.
