[0032] As a preferred solution of the present utility model, the fixing mechanism includes: control board 9, two auxiliary rods 11 and auxiliary plate 13;

[0033] The control panel 9 is fixedly connected to the top of the plugboard 15 on the left side, the two auxiliary rods 11 are rotatably connected to the front sides of the corresponding plugboards 15, and the auxiliary plate 13 is rotatably connected to the rear sides of the two auxiliary rods 11. The movement of the control panel 9 will drive the left plugboard 15 to move right, and the movement of the left plugboard 15 will push the left auxiliary rod 11. At this time, the movement of the auxiliary rod 11 will push the auxiliary panel 13 upward, and the upward movement of the auxiliary panel 13 will pull the auxiliary rod 11 on the right, and the movement of the auxiliary rod 11 on the right will drive the right plugboard 15 to move left. At this time, the two plugboards 15 move toward the side close to each other and disengage from the slots.

[0039] The working principle of the utility model is as follows: in actual use, the base 1 is placed in a suitable position, and the object to be tested is placed on the top of the base 1. When the height of the pendulum 6 needs to be adjusted, the control plate 9 is first pushed to move right, and the movement of the control plate 9 will drive the plugging plate 15 on the left to move right. When the control plate 9 moves, the reset spring 10 is compressed, and the movement of the plugging plate 15 on the left will push the auxiliary rod 11 on the left. At this time, the movement of the auxiliary rod 11 will push the auxiliary plate 13 to move upward, and the upward movement of the auxiliary plate 13 will compress the limit spring 14.

At this time, the two plugging plates 15 move to the side close to each other and disengage from the slot, thereby causing the lifting. The lowering plate 3 is unlocked, and the lifting plate 3 can be pushed to move up and down. The movement of the lifting plate 3 can drive the pendulum 6 to move. When the pendulum 6 moves to a suitable height, the control plate 9 is released. At this time, the reset spring 10 loses its restriction and pushes the left plug plate 15 to reset. At the same time, the limit spring 14 pushes the auxiliary plate 13 to move downward. The downward movement of the auxiliary plate 13 will push the two auxiliary rods 11. The reset of the two auxiliary rods 11 will push the two plug plates 15 to move away from each other. The plug plates 15 are reset and engaged with the slots to fix the lifting plate 3, thereby fixing the pendulum 6 at the current height. By starting the motor 7, the rotation of the output shaft of the motor 7 will drive the transmission rod 4 to rotate. The rotation of the transmission rod 4 will drive the connecting arm 5 to rotate, thereby driving the pendulum 6 to move, and an impact test is performed on the object.
