[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, when the output shaft of the electric telescopic rod b is extended, the hardness detection seat drives the two hardness detection blocks to move, thereby facilitating the detection of different electric tool strikers. After the output shaft of the electric telescopic rod b is extended, the hardness of multiple electric tool strikers can be detected, thereby improving the hardness detection efficiency of the electric tool strikers. When the output shaft of the electric telescopic rod b is extended and the resistance exceeds a preset range, the control panel first controls the electric telescopic rod b to stop working, and then controls the output shafts of the two electric telescopic rods a to retract, so that the output shafts of the two electric telescopic rods a are separated from the two limiting grooves. Thereafter, the control panel controls the output shaft of the electric telescopic rod b to continue to extend, and then controls the output shafts of the two electric telescopic rods a to continue to extend, so that the output shafts of the two electric telescopic rods a continue to be inserted into the two limiting grooves.

[0020] In addition, when the output shafts of the two electric telescopic rods a are in a retracted state and the output shaft of the electric telescopic rod b continues to extend, under the action of the electric tool striker and the hardness detection block below, the rectangular movable block can drive the electric telescopic rod b to slide upward; when the hardness detection block below passes the corresponding electric tool striker, under the action of gravity, the rectangular movable block can drive the electric telescopic rod b to slide downward, so that the bottom of the rectangular movable block contacts the clamping limit seat on the right.

[0021] 2. The present invention facilitates the staff to select a hardness test block of appropriate thickness according to the hardness test requirements; when the output shaft of the electric telescopic rod b is extended, if the hardness test block below can directly pass over the corresponding electric tool striker, it indicates that the electric tool striker is deformed and the hardness test of the electric tool striker fails; when the output shaft of the electric telescopic rod b is extended, if the hardness test block below cannot directly pass over the corresponding electric tool striker, it indicates that the electric tool striker is not deformed and the hardness test of the electric tool striker passes;

[0022] In addition, when the output shaft of the electric telescopic rod b is extended, the hardness testing seat drives the four circular clamping rods to move. When the two circular clamping rods below come into contact with the two force-bearing protrusions, the two clamping limit rods move downward, realizing the clamping limit of a row of power tool strikers; when the two circular clamping rods below are separated from the two force-bearing protrusions, the two clamping limit rods move upward under the action of four coil springs, so that a gap is generated between the two clamping limit rods and the row of power tool strikers after hardness testing, which makes it convenient for the staff to remove the row of power tool strikers after hardness testing, and also makes it convenient for the staff to place the row of power tool strikers to be tested.

[0023] 3.

The hardness is improved, and the hardness detection efficiency of the electric tool striker 200 is improved; when the output shaft of the electric telescopic rod b405 is extended and the resistance is detected to exceed the preset range, the control panel 603 first controls the electric telescopic rod b405 to stop working, and the control panel 603 then controls the output shafts of the two electric telescopic rods a404 to retract, so that the output shafts of the two electric telescopic rods a404 are separated from the two limiting grooves 4011, and then the control panel 603 controls the output shaft of the electric telescopic rod b405 to continue to extend, and then the control panel 603 controls the output shafts of the two electric telescopic rods a404 to extend, so that the output shafts of the two electric telescopic rods a404 continue to be inserted into the two limiting grooves 4011; when the output shafts of the two electric telescopic rods a404 are When the electric telescopic rod b405 is in the retracted state and the output shaft of the electric telescopic rod b405 continues to extend, under the action of the electric tool striker 200 and the hardness detection block 502 below, the rectangular movable block 402 can drive the electric telescopic rod b405 to slide upward; when the hardness detection block 502 below passes over the corresponding electric tool striker 200, under the action of gravity, the rectangular movable block 402 can drive the electric telescopic rod b405 to slide downward, so that the bottom of the rectangular movable block 402 contacts the clamping limit seat 301 on the right side; when the output shaft of the electric telescopic rod b405 is extended, if the hardness detection block 502 below can directly pass over the corresponding electric tool striker 200, it indicates that the electric tool striker 200 is deformed and the hardness test of the electric tool striker 200 fails.When the output shaft of the electric telescopic rod b405 is extended, the hardness test block 502 below cannot directly pass over the corresponding power tool striker 200, indicating that the power tool striker 200 is not deformed and the power tool striker 200 has passed the hardness test. When the two circular clamping rods 503 below separate from the two force-bearing protrusions 3031, the two clamping limit rods 303 move upward under the action of the four coil springs 304, creating a gap between the two clamping limit rods 303 and the row of power tool strikers 200 that have undergone hardness testing. This makes it easier for workers to remove the row of power tool strikers 200 that have undergone hardness testing and also facilitates the placement of the row of power tool strikers 200 to be tested.
