Then, after a certain switch on the starting circuit, when the capacitor discharges, the voltage value is not sufficient to make it conduct, and it returns to the high - impedance state. When the capacitor charges to the set value, it triggers cyclically.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0022] The following will be combined with Figures 1-4 to further elaborate on this application.

[0023] An embodiment of this application discloses a high-voltage trigger transistor. Refer to Figure 1 and Figure 4 , a high-voltage trigger transistor includes a high-voltage trigger transistor body 1, a sealing mechanism 2 is arranged on the surface of the high-voltage trigger transistor body 1, and a thread rotation mechanism 3 is arranged on the surface of the sealing mechanism 2;

[0024] The sealing mechanism 2 includes a fixed block 201, the surface of the fixed block 201 is fixedly connected to the surface of the high-voltage trigger transistor body 1, a moving block 202 is movably connected to the inner cavity of the fixed block 201, the number of the moving blocks 202 is two, connecting blocks 207 are fixedly connected to the surfaces of both moving blocks 202, and a clamping arm 208 is fixedly connected to the surface of the connecting block 207, and the inner cavity of the clamping arm 208 is movably connected to the surface of the high-voltage trigger transistor body 1.

[0025] Refer to Figure 3 , a guide groove 204 is opened in the inner cavity of the fixed block 201, a guide block 206 is movably connected to the inner cavity of the guide groove 204, the number of the guide blocks 206 is four, and the surfaces of every two guide blocks 206 are fixedly connected to the surface of a connecting block 207. By setting the guide groove 204 and the guide block 206 to cooperate with each other, it provides a guiding effect for the connecting block 207 to move in the inner cavity of the fixed block 201, and avoids unnecessary shaking when the connecting block 207 moves in the inner cavity of the fixed block 201;

[0026] Refer to Figure 3 and Figure 4, two stoppers 205 are fixedly connected to the inner cavity of each guiding groove 204. Through the arrangement of the stoppers 205, when the guiding block 206 contacts the stopper 205 during the movement of the guiding block 206, the guiding block 206 reaches the maximum moving distance, which avoids the guiding block 206 detaching from the inner cavity of the fixing block 201 during the movement, and indirectly avoids the moving block 202 detaching from the inner cavity of the fixing block 201 during the movement;

[0027] Refer to Figure 2 , a soft sealing pad 209 is fixedly connected to the inner cavity of the clamping arm 208, and the inner cavity of the soft sealing pad 209 contacts the surface of the high-voltage trigger transistor body 1. Through the arrangement of the soft sealing pad 209, since the soft sealing pad 209 is made of soft rubber material, deformation will occur when the soft sealing pad 209 is in close contact with the electrodes in the high-voltage trigger transistor body 1, so as to fill the gap between the clamping arm 208 and the tube body in the high-voltage trigger transistor body 1, thereby improving the airtightness of the connection between the tube body and the electrodes in the high-voltage trigger transistor body 1;

[0028] Refer to Figure 3 , the threaded rotation mechanism 3 includes a rotating block 301, a threaded rod 302 is fixedly connected to the surface of the rotating block 301, the surface of the threaded rod 302 is threadedly connected to the inner cavity of the fixing block 201, one end of the threaded rod 302 is movably connected to a trapezoidal block 304, and the surface of the trapezoidal block 304 is movably connected to the surface of the moving block 202. By setting the rotating block 301, the threaded rod 302 and the trapezoidal block 304 to cooperate, when the rotating block 301 is rotated, the threaded rod 302 can be driven to move while rotating in the inner cavity of the fixing block 201, thereby pushing the trapezoidal block 304. The trapezoidal block 304 slides on the surface of the moving block 202 through the inclined surface, thereby driving the moving block 202 to move outward, indirectly causing the clamping arm 208 and the soft sealing pad 209 to lose close contact with the electrodes in the high-voltage trigger transistor body 1;

[0029] Refer to Figure 3 , sliding grooves 210 are formed on the surfaces of the two moving blocks 202, a sliding block 203 is movably connected to the inner cavity of each sliding groove 210, and the surface of the sliding block 203 is fixedly connected to the surface of the trapezoidal block 304. By setting the sliding block 203 and the sliding groove 210 to cooperate, when the trapezoidal block 304 moves towards the threaded rod 302, the sliding block 203 can be driven to slide in the inner cavity of the sliding groove 210, and the moving block 202 is driven to move inward, indirectly driving the clamping arm 208 and the soft sealing pad 209 to move inward to clamp the electrodes in the high-voltage trigger transistor body 1;

[0030] Refer to Figure 3, a bearing 303 is fixedly connected to the surface of the threaded rod 302, and the outer ring of the bearing 303 is fixedly connected to the surface of the trapezoidal block 304. Through the setting of the bearing 303, the threaded rod 302 can not only push the trapezoidal block 304 while moving, but also pull the trapezoidal block 304 when the threaded rod 302 moves due to the fixation of the inner and outer rings of the bearing 303 to the threaded rod 302 and the trapezoidal block 304 respectively.

[0031] Working principle: When increasing the airtightness of the connection between the electrode and the tube body in the high-voltage trigger transistor body 1, first rotate the rotating block 301. While the rotating block 301 drives the threaded rod 302 to rotate threadedly in the inner cavity of the fixed block 201 and move outward from the fixed block 201, the threaded rod 302 drives the bearing 303 to rotate, the bearing 303 drives the trapezoidal block 304 to move, and the trapezoidal block 304 drives the sliding block 203 to slide in the inner cavity of the moving block 202. When the trapezoidal block 304 moves towards the rotating block 301, it drives the two moving blocks 202 to move inward. The moving block 202 drives the connecting block 207 to move, the connecting block 207 drives the clamping arm 208 to move, and the clamping arm 208 drives the soft sealing pad 209 to be in close contact with the electrode in the high-voltage trigger transistor body 1. Since the soft sealing pad 209 is made of soft rubber material, when the soft sealing pad 209 is in close contact with the electrode in the high-voltage trigger transistor body 1, it will be squeezed and fill the gap between the clamping arm 208 and the tube body in the high-voltage trigger transistor body 1, thereby increasing the airtightness of the connection between the surface of the clamping arm 208 and the tube body in the high-voltage trigger transistor body 1, and thus improving the airtightness of the connection between the electrode and the tube body in the high-voltage trigger transistor body 1.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
