the spring electrode further comprises a spring washer (9); wherein the spring washer (9) is arranged between the electrode holder (18) and a boss (62) of the intermediate deck section (6);
the head electrode (15) and the core rod (4) have a distance of 0-3 mm;
the tail test feedback module (20) comprises a light emitting diode and a buzzer, wherein the light emitting diode is bright when a loop of the thrust test pen is closed, and the buzzer rings;
the adjusting screw (8) is made of stainless steel, and a screw head at the tail part of the adjusting screw (8) is in a regular hexagon shape and is matched with the inner shape of the middle cabin section;
a button battery (10) is loaded in the battery bin (11);
further comprising: a protective cap (100); wherein the protective cap (100) can be sleeved on the test head (1);
the electrode seat is made of non-metal materials, after the electrode seat is connected with the middle cabin section through surface threads, a distance of 0-3 mm exists between the head electrode and the spring core rod in a natural state, namely a measuring stroke, and the distance can be adjusted by adding a spring washer; the tail electrode is connected with the cathode of the battery bin, when the thrust of a tested object exceeds a set spring compression force during a thrust test, the spring core rod moves the head electrode touching the spring electrode towards the tail, a closed loop is formed inside the thrust test pen, and an acousto-optic device of the tail test feedback module works simultaneously to give sound and light feedback;
the method for performing the thrust test by using the thrust test pen comprises the following steps:
(1) Installing a head cabin section, a middle cabin section, a spring core rod, an adjusting screw rod, a spring electrode, a battery cabin, a tail test feedback module and the like, and entering the step (2) if a test end is not installed temporarily;
(2) Testing the thrust of the thrust pen by using a qualified push-pull dynamometer, slowly pushing the head of the spring core rod to be vertical to a test surface of the push-pull dynamometer at a constant speed until an acousto-optic loop of a test feedback module at the tail of the thrust pen is conducted, stopping pushing, rotating the head cabin section to adjust the thrust of the thrust pen according to a peak value and a target test value shown by the push-pull dynamometer, and if the thrust of three continuous tests is above the target test value, considering that the thrust adjustment is finished, and entering the step (3);
(3) Selecting a proper test end according to the object to be tested, mounting the test end on the head cabin section by using a tail tool, and automatically mounting and adjusting the power assisting ring and the pen clip as required to enter the step (4);
(4) The test end is perpendicular to a tested object, after the test end is contacted with the tested object, a hand holding the pen is parallel to the pen holder and applies force downwards at a constant speed, the force application time is controlled to be 0-2 seconds, the diode of the tail test feedback module is bright, the buzzer rings to prompt that the test is passed, the tail test feedback module does not prompt that the test is not passed, and the tested object is abnormally installed;
(5) The thrust test pen protective cap is installed in the test end after the thrust pen is adjusted or used.
