[0002] At present, mechanical targets are widely used in various physical shooting game devices. Generally, the mechanical targets can be driven by a driving device to perform high-frequency reciprocating motions of falling down or standing up. In the traditional technology, the driving device drives the mechanical target in the following way: a rotating rod is connected to the shooting target surface through a connecting piece, and the driving device or driving motor drives the movement of the rotating rod to drive the entire shooting target surface to move.

[0017] The beneficial effects of the present invention are:

[0018] (1) By setting the inverted assembly, the technical effect that can be achieved is that the LED light is started, and the light is displayed on the fixed target surface. After the user shoots, the fixed target surface is hit and subjected to force, and the motor servo receives the signal and starts, driving the auxiliary rotating rod to rotate forward along the motor shaft of the motor servo, driving the magnetic part to rotate forward, and driving the driving rotating rod to rotate along the driving rod. When the driving rotating rod moves into place, the optical coupling switch detects the signal and transmits it to the motor servo, and the motor servo stops working;

The first motor controls the replacement slide rail to move to the right along the replacement guide rail, and the second motor controls the recovery slide rail to move to the left along the recovery guide rail. After the replacement slide rail and the recovery slide rail are moved into place, the telescopic cylinder receives the signal and extends, and the scissors fork slides along the first waist-shaped hole and the second waist-shaped hole, driving the upper platform to move upward, and the telescopic part extends forward to make the suction cup contact with the fixed target surface. Then, the drive motor is started to adsorb the fixed target surface on the suction cup, and the moving component adsorbs the fixed target surface through the suction cup, and the movement of the fixed target surface is realized through the scissors fork and the drive trolley. The target surface can be automatically controlled to be removed and installed through the circuit board, so as to prevent accidental injury during manual target replacement, reduce personnel costs, and make target replacement more automated and portable.

[0022] (3) By setting a replacement component, the technical effect that can be achieved is that the replacement shell is located at the lower end of the lower base plate, the right side of the replacement shell is open, the inner bottom of the replacement shell is fixedly connected with a replacement guide rail, the replacement slide rail is slidably connected to the replacement guide rail, four upper limit blocks are fixedly arranged on the replacement slide rail, a plurality of target surfaces to be replaced are arranged between the four upper limit blocks, and a first motor is fixedly arranged on the replacement slide rail; the moving motor is started to control the driving trolley to move to the right, the driving motor is turned on, the suction cup absorbs the target surface to be replaced between the four upper limit blocks, the telescopic cylinder is extended to move the upper platform upward, the driving trolley is controlled to move to the left to the upper shell, the upper platform descends, and after the target surface to be replaced and the driving rotating rod are installed, the driving motor is turned off to complete the replacement of the fixed target surface, and the replacement component can move the replacement slide rail through the replacement guide rail, and the four upper limit blocks are used to limit the target surface to be replaced to prevent the target surface to be replaced from falling or failing to align the position, which results in the inability to correctly install the target surface to be replaced.

[0023] (4) By setting up a recovery component, the technical effect that can be achieved is that the left side of the recovery shell is open, the inner bottom of the recovery shell is fixedly connected to a recovery guide rail, the recovery slide rail is slidably connected to the recovery guide rail, four lower limit blocks are fixedly arranged on the recovery slide rail, a plurality of target surfaces to be recovered are arranged between the four lower limit blocks, and a second motor is fixedly arranged on the recovery slide rail; the moving motor is started to control the driving trolley to move to the left, the telescopic cylinder is contracted to move the upper platform downward, and then the driving motor is turned off to fix the target surface to separate from the suction cup and place it between the four lower limit blocks. The recovery component can move the recovery slide rail through the recovery guide rail, and the four lower limit blocks are used to limit the old target surface to prevent the old target surface from falling out of the recovery slide rail and becoming unable to be recovered.
