The handle 240 is used to provide convenience for rotating the screw rod 230. The shell 200 is fixedly connected to the bottom of the first shield body 100, and the shell 200 is used to support the first shield body 100.

[0030] Please refer again Figure 1-4A baffle 110 is fixedly connected to the lower side of the left side wall of the shell 200 and the left side of the top of the shell 200. The baffle 110 is made of rubber material. The baffle 110 made of rubber material has high cushioning performance.

[0031] Please refer again Figure 1-4 Elastic members 160 are fixedly connected between the four corners of the front side wall of the inner cavity of the second shell 150 and the four corners of the rear side wall of the inner cavity of the first shell 120. The elastic members 160 are made of stainless steel. The elastic members 160 made of stainless steel have high strength.

[0032] Please refer again Figure 1-4 An observation window 190 is inlaid in the middle of the upper side of the front side wall of the first shield body 100. The observation window 190 is made of polycarbonate material. The observation window 190 made of polycarbonate material has high puncture resistance and impact resistance.

[0033] Please refer again Figure 1-4 The outer wall of the screw rod 230 is threadedly connected with a slider 250, and the slider 250 is slidably connected between the inner cavity of the positioning shell 220 and the inner cavity of the through hole 210. The slider 250 can cooperate with the screw rod 230 to drive the second shield body 260 to move up and down.

[0034] Please refer again Figure 1-4 The front side wall of the slider 250 is fixedly connected with a second shield body 260 , and the second shield body 260 is slidably connected to the inner cavity of the shell 200 , so that the slider 250 can be moved out of the shell 200 through the second shield body 260 .

[0035] In summary, the shell 200 is provided to provide a storage space for the second shield body 260, and then the handle 240 drives the screw rod 230 to rotate, driving the screw rod 230 to cooperate with the positioning shell 220 and the through hole 210 to drive the slider 250 to drive the second shield body 260 in and out of the shell 200, thereby adjusting the overall size of the security explosion-proof shield, so that the security explosion-proof shield as a whole can be adjusted and retracted, occupies a small space, and is easy to store.

[0036] In summary, the baffle 110 is provided to buffer the impact for the first time, and then the first shell 120 cooperates with the second shell 150 and the elastic member 160 to absorb the impact force for the second time, and cooperates with the slide groove 130 and the damping block 140 to complete the buffering, thereby reducing the impact force on the arm holding the handpiece 180, so that the security explosion-proof shield has a buffering mechanism, which is convenient for buffering the impact force on the security explosion-proof shield, making it difficult for the staff's arms to be injured and easy to use.

[0037] During specific use, a person skilled in the art first holds the handle 240 to rotate the screw rod 230, driving the screw rod 230 to rotate under force and drive the slider 250 to move downward, and the slider 250 drives the second shield body 260 to move out of the shell 200 until the second shield body 260 moves to a specified position. When the security explosion-proof shield is subjected to an impact force, if it falls on the baffle 110, the baffle 110 made of rubber material will buffer the impact force for the first time, and then the impact force will be transmitted through the first shield body 100 and the first shell 120, driving the elastic member 160 inside the first shell 120 and the second shell 150 to absorb the impact force, and then the slide groove 130 cooperates with the damping block 140 to buffer the force released after the elastic member 160 is compressed, thereby reducing the impact force on the human body.
