A taser firing control mechanism

Abstract

This invention discloses a firing control mechanism for an electric firing pistol. It is fully functional, safe, and reliable, featuring a motor-driven lead screw, a rotating bolt head for opening and closing, a proximity switch for limit switches, a servo motor, and a variable-diameter cam for firing control. It also includes a safety feature. A servo motor is mounted on one side of the receiver and connected to the lead screw via gear reversal. The lead screw drives the bolt frame to reciprocate back and forth via a threaded connection. The bolt frame, driven by the helical surface of the bolt head, follows the movement and completes the opening and closing. The proximity switch controls the maximum travel range of the bolt frame. The automatic mechanism employs a firing pin translation type. The firing pin is installed inside the bolt frame and stores and releases energy by compressing the firing pin spring to strike the primer of the ammunition, thus completing the firing. The firing pin's catch ramp engages with the firing mechanism component. Before firing, the firing pin disengages from the firing mechanism component and strikes the primer under the force of the firing pin spring. The firing mechanism component has a manual safety feature; in the "manual safety closed" state, the firing pin cannot disengage from the firing mechanism component to complete the primer striking action.

Description

Technical Field

[0001] This invention relates to the field of electric firing gun technology, and in particular to a firing control mechanism for an electric firing gun. Background Technology

[0002] In the context of the development of weaponry towards unmanned, intelligent, modular, and platform-integrated installation, it is necessary to research and develop an electric firing control mechanism to meet the control and firing function requirements for electric firing firearms integrated, installed, and used on the platform. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electric firing gun firing control mechanism that is fully functional, safe and reliable, and meets the installation and use requirements of intelligent firearm platforms.

[0004] The objective of this invention is achieved as follows:

[0005] A firing control mechanism for an electric firing pistol includes a receiver, a sleeve fixed inside the receiver, and a sliding frame. A head and a tail are mounted inside the frame. The sleeve is located in front of the head. The head has a tenon, and the frame has a helical surface. The tenon slides against the helical surface, allowing the head to move helically along the surface and follow the frame's movement to complete opening and closing actions. A firing pin and a firing pin spring are mounted inside the head, with the spring fitted onto the firing pin. The rear end of the firing pin is circumferentially limited by the tail.

[0006] The firing pin has a firing pin catch ramp at its tail. A transmitter assembly is mounted below the receiver, including a transmitter housing. Inside the transmitter housing are a safety, a sear, and a firing lever. The safety is rotatable and is rod-shaped with a locating recess on its circumference. The transmitter housing contains a safety pin and a pin spring. The safety pin, under the force of the pin spring, abuts against the locating recess on the safety, providing elastic positioning and locking the safety in its open or closed state. The safety has a cut-shaped flat surface. The sear is inverted L-shaped, with its corner hinged to the transmitter housing. The surface of the sear corresponding to the safety is the sear seat. The sear is hinged to the other side of the sear base. The sear is unidirectionally positioned on the sear base and can rotate unidirectionally, allowing the firing pin to move backward to complete the firing pin mounting. During firing pin mounting, the firing pin mounting ramp is normally in contact with the sear. When the circumferential surface of the safety device is facing the sear base's working surface, the safety device is in the closed state, restricting the rotation of the sear base. When the flat surface on the safety device is facing the sear base's working surface, the safety device is in the open state, allowing the sear base to rotate and the firing pin mounting ramp to disengage from the sear. A torsion spring is provided on the lower side of the sear base, acting on the sear. Under the force of the torsion spring, the sear and the sear base can rotate upward together to reset.

[0007] The firing lever is hinged to the launcher housing. A firing torsion spring is installed between the firing lever and the launcher housing. Under the action of the firing torsion spring, one end of the firing lever normally contacts the working surface of the sear seat, restricting the rotation of the sear seat and thus restricting the firing pin from disengaging and firing. A servo motor is installed on one side of the launcher housing. The servo motor's shaft is connected to a variable diameter cam, which is located inside the launcher housing. The servo motor can drive the variable diameter cam to push open the firing lever. After the firing lever rotates, it disengages from the working surface of the sear seat. Under the action of the firing pin spring force, the sear rotates and moves to make room, allowing the firing pin to disengage from the sear and slide forward to complete the firing action.

[0008] The housing contains a rotatable lead screw, on which a servo motor is mounted. The lead screw and servo motor are connected via a gear set. A transmission nut is threaded onto the lead screw, and its lower end is fixedly connected to the frame, allowing the servo motor to drive the frame to slide back and forth. A hinged anti-rotation catch is mounted on one side of the frame. One end of the anti-rotation catch is supported by an anti-rotation catch spring, while the other end, under the action of the anti-rotation catch spring, restricts the machine head to one end of the machine head helical surface on the frame, preventing relative movement between the machine head and the frame. An anti-rotation catch spring is mounted on the front end of the housing corresponding to the anti-rotation catch. One end is equipped with a locking block, and the end of the locking block corresponding to the anti-rotation locking block is equipped with an anti-rotation locking block downward pressure slope. The bolt carrier drives the bolt head to slide forward and complete the feeding action. During the sliding of the bolt carrier, the firing pin spring is compressed and stores energy. After the bolt head enters the sleeve, the anti-rotation locking block contacts the anti-rotation locking block downward pressure slope, causing the end of the anti-rotation locking block with the anti-rotation locking block spring to press down. The anti-rotation locking block spring is compressed, the anti-rotation locking block opens, and the restriction on the bolt head is released. The bolt head rotates back to lock and feed the bullet into the chamber. After the bolt head rotates back and locks, the firing pin catch slope and the sear of the firing mechanism are engaged. The firearm is ready to fire.

[0009] Preferably, the servo motor and gear set are installed at the rear end of the casing, and the size of the two gears in the gear set is selected according to the reduction ratio.

[0010] Preferably, proximity switches are installed at the front and rear ends of one side of the casing. The two proximity switches control the maximum travel range of the frame. When the frame moves back and forth, if the transmission nut blocks the tip of one proximity switch, the proximity switch sends a feedback signal, causing the servo motor to stop rotating, thereby stopping the frame from moving.

[0011] Preferably, the casing is provided with a frame mounting groove, in which the frame slides and is circumferentially limited.

[0012] Preferably, the lower part of the housing is provided with a transmitter component mounting notch and a transmitter component threaded mounting hole; a positioning duckbill is provided at the front of the transmitter box, which engages with the transmitter component mounting notch; and a screw through hole is provided at the rear of the transmitter box, which is fixed to the transmitter component threaded mounting hole by a screw.

[0013] Preferably, an anti-rotation clamp mounting part is provided on one side of the machine frame. The anti-rotation clamp mounting part includes mutually perpendicular anti-rotation clamp support spring mounting holes and anti-rotation clamp shaft pin holes. The middle part of the anti-rotation clamp is hinged to the anti-rotation clamp shaft pin holes via a shaft. The anti-rotation clamp has a contact part with the clamp pressure block, a force-bearing part with the clamp support spring, and a contact part with the machine head tenon. The contact part with the machine head tenon is located at one end of the anti-rotation clamp. The contact part with the clamp pressure block and the force-bearing part with the clamp support spring are arranged opposite to each other and are both located at the other end of the anti-rotation clamp. An anti-rotation clamp support spring is installed in the anti-rotation clamp support spring mounting hole. The anti-rotation clamp support spring acts on the force-bearing part of the clamp support spring, so that the contact part with the machine head tenon is normally engaged with the machine head tenon.

[0014] Preferably, locking teeth are symmetrically arranged on both sides of the front end of the bolt head, and locking force-bearing surfaces are symmetrically arranged on both sides inside the sleeve. The end face of the bolt head tenon is provided with a part that interacts with the anti-rotation catch. When the anti-rotation catch is in the restricted state, the part interacting with the anti-rotation catch restricts the bolt head from sliding along the bolt head spiral surface. When the anti-rotation catch is not restricted, the bolt frame can push the bolt head, and the bolt head slides spirally along the bolt head spiral surface. Then, the bolt head locking teeth enter the bolt head locking force-bearing surface of the sleeve and complete the rotation locking, bearing the gunpowder pressure at the moment of ammunition firing after locking.

[0015] Preferably, the rear end of the tail section is provided with a firing pin retaining ramp groove along the axis for guiding the firing pin forward; the tail section is provided with a firing pin mounting through hole; the middle of the tail section is provided with a firing pin spring limiting surface, which contacts and limits the firing pin spring at the tail end, so that the firing pin spring is in a pre-compressed state and stores energy for the firing pin.

[0016] Preferably, a limiting boss is symmetrically provided at the front of the tail section, and the limiting boss is assembled with the tail mounting position at the tail of the frame to restrict the tail section to the tail section of the frame; an anti-rotation notch is also provided in the middle of the tail section to restrict the circumferential rotation of the tail section using a pin.

[0017] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0018] Its structure is simple and reliable, with a manual safety function. It adopts a servo motor drive, gear reversing, lead screw transmission, anti-rotation lock, rotation lock, proximity switch limit, and servo motor control for firing. This control mechanism is fully functional, safe and reliable, and can be modularly designed to adapt to use in electric firing firearms of different calibers. Attached Figure Description

Detailed Implementation

[0043] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] See Figures 1-15This is an embodiment of a firing control mechanism for an electric firing pistol. It includes a motor-driven lead screw, a rotating bolt head for opening and closing, a proximity switch for limit switches, a servo motor, and a variable-diameter cam for firing control. It also features a firing pin-type firing control mechanism with a safety function. A servo motor is mounted on one side of the receiver and connected to the lead screw via gear reversal. The lead screw drives the bolt frame to reciprocate back and forth via a threaded connection. The bolt frame, driven by the helical surface of the bolt head, follows the bolt frame's back and forth movement and rotates to complete the opening and closing action. Proximity switches are installed at both ends of the receiver side to control the maximum travel range of the bolt frame. The automatic mechanism uses a firing pin translation type. The firing pin is installed inside the bolt frame and stores and releases energy by compressing the firing pin spring to strike the primer of the ammunition, thus completing the firing. The firing pin catch ramp engages with the firing mechanism components. Before firing, the firing pin disengages from the firing mechanism components and strikes the primer under the force of the firing pin spring. The transmitter assembly has a manual safety mechanism. In the "manual safety closed" state, the firing pin cannot disengage from the transmitter assembly to complete the primer firing action. To switch the manual safety from the closed state to the "safety open" state, the servo motor rotates approximately 120 degrees, driving the variable-diameter cam to disengage the firing lever from the sear, thus completing the firing mechanism's action. Specifically:

[0045] like Figure 3 , Figure 4 As shown, the casing 1 has a frame mounting groove 101 inside, which is a cross-shaped groove. The frame and the head can move freely back and forth in it, and it also serves to prevent the frame from rotating. A sleeve mounting hole 102 is provided at the front of the casing. The sleeve mounting hole 102 is an inner hole for pressing the sleeve 11 into the casing 1. The sleeve 11 is press-fitted with the casing 1. There are two locking block mounting holes 103 on the left side of the casing. These are through holes where the locking block 14 is riveted. There are also two threaded holes (104 is the first proximity switch mounting hole, and 105 is the second proximity switch mounting hole) on the left side of the casing 1 for mounting two proximity switches 12. Inside the casing 1, a circular hole for accommodating a lead screw is provided directly above the frame mounting slot 101. A lead screw front bearing mounting hole 106 is provided in front of the circular hole, and a lead screw rear bearing mounting hole 107 is provided behind the circular hole. Below the casing 1, there is a transmitter component mounting notch 108 and a transmitter component threaded mounting hole 109. The transmitter component mounting notch 108 is used to lock the front end of the transmitter component, and the transmitter component threaded mounting hole 109 is used to position and fix the transmitter component. At the rear of the casing, there are also 4 motor mount threaded holes 1010. The motor mount threaded holes 1010 are used to mount motor mounts, and servo motors 13 are then mounted on the motor mounts.

[0046] like Figure 5 As shown, the front end of the lead screw 3 is provided with a first gear mounting position 201 and a front bearing mounting position 202; the rear end of the lead screw 3 is provided with a rear bearing mounting position 204; the middle part of the lead screw is the lead screw threaded part 203, which cooperates with the transmission nut 3 to transmit the transmission frame 4 and the machine head 5.

[0047] like Figure 6 As shown, the internal through hole of the transmission nut 3 is provided with the internal thread 301 of the transmission nut, which is used in conjunction with the lead screw 2; the lower part of the transmission nut 3 is provided with the mounting part 302 for the transmission nut and the machine frame.

[0048] like Figure 7 As shown, the front circumferential part of the frame 4 is provided with a spiral surface 401 (spiral groove) for the machine head, which slides in conjunction with the tenon 501 of the machine head; the upper part of the frame 4 is provided with a frame and transmission nut mounting part 404, and the side is also provided with two connecting pin holes 402 (interference pin mounting holes) to fix the frame 4 and the transmission nut 3 together; the left side of the frame 4 is provided with an anti-rotation bracket mounting part, the anti-rotation bracket mounting part is provided with an anti-rotation bracket support spring mounting hole 403, and the mounting part is also provided with an anti-rotation bracket shaft pin hole 405 in the vertical direction. The anti-rotation bracket can rotate around the shaft under the action of the support spring force. The rear of the frame 4 is provided with a tail mounting position 406.

[0049] like Figure 8 As shown, two machine head locking teeth 502 are symmetrically arranged on the left and right sides in front of the machine head 5. A machine head tenon 501 is provided on the rod part of the machine head 5 on the left side of the machine head locking tooth. The machine head tenon 501 slides and engages with the machine head spiral surface 401 of the machine frame 4. The tip of the machine head tenon 501 is provided with a part 503 that interacts with the anti-rotation clamp. This part is a side groove. When it is clamped by the anti-rotation clamp, it restricts the machine head 5 from sliding spirally along the machine head spiral surface 401. When there is no anti-rotation clamp, the machine frame 4 pushes the machine head 5, and the machine head 5 rotates along the machine head spiral surface 401. The machine head locking teeth 502 enter the sleeve 11 and complete the rotation locking.

[0050] like Figure 9 As shown, a gear and lead screw mounting interface 601 is provided in the middle of the gear 6 to restrict the relative circumferential rotation of the gear and lead screw.

[0051] like Figure 10 As shown, the tail section 7 has a firing pin holder ramp clearance groove 701 along the axis at its rear end, which is used to allow the firing pin 8 to strike forward; the tail section 7 has a firing pin mounting through hole 702 inside; the middle of the tail section has a firing pin spring limiting surface 703, which puts the firing pin spring 10 in a pre-compressed state and stores energy for the firing pin; the front of the tail section 7 has symmetrically circumferential ...

[0052] like Figure 11 As shown, the firing pin 8 component has a firing pin retaining ramp 801 at its tail end, which is used to connect with the transmitter component 9. In the assembled state, the firing pin spring 10 is fitted onto the firing pin 8.

[0053] like Figure 12 As shown, the components of transmitter component 9 are integrated and mounted on transmitter housing 901. A (manual) safety 907 is installed laterally through a through-hole within transmitter housing 901. A safety pin 902 is provided inside transmitter housing 901. Under spring force, the safety pin abuts against a positioning recess on the rod of safety 907, restricting axial movement and circumferential rotation of the safety in its free state. A flat surface is provided on the rod of safety 907. When safety 907 is manually rotated, and the flat surface is aligned with the action surface of sear seat 904, safety 907 is in the open state, and transmitter component 9 is ready to release the trigger. The firing pin 8 completes the firing condition. In the safe position, manually rotate the safety 907 to 90°. At this time, the circumference of the safety lever is directly opposite the sear seat's working surface, and the safety 907 is in the closed position, restricting the sear seat's rotation. The firing pin 8 cannot be released to complete the firing action. The sear seat 904 is mounted inside the transmitter housing 901 via a pin. The sear 903 is mounted inside the sear seat 904 via a pin. Both the sear 903 and the sear seat 904 can rotate freely around their respective pins. Under the action of the torsion spring below the sear seat 904, the sear 903... 03 and the sear seat 904 can reset upwards together; a firing lever 905 is also installed on the transmitter housing 901 via a pin. The firing lever 905 abuts against the sear seat 904, restricting the sear seat from rotating, thereby preventing the firing pin 8 from disengaging. It can rotate and reset under the force of the torsion spring; the servo motor 908 is installed on one side of the transmitter housing 901 by screws. The variable diameter cam 906 is connected to the servo motor 908's shaft through longitudinal teeth, and the end face is pressed and fixed with screws; during assembly, the minor diameter of the variable diameter cam 906 just contacts the firing lever's abutment, triggering the safety mechanism. In the open state, the servo shaft rotates about 120°, and the large diameter of the variable diameter cam abuts against the firing lever, causing the firing lever 905 to rotate and disengage from the sear seat. Under the action of the firing pin spring, the firing pin can disengage from the sear and slide forward to complete the firing action. A positioning duck tongue 901-1 is provided at the front of the transmitter box 901, which cooperates with the transmitter component mounting notch 108. A screw through hole 901-2 is provided at the rear of the transmitter box 901, which is fixed to the transmitter component threaded mounting hole 109 by screws, completing the overall integrated installation of the transmitter component and the housing.

[0054] like Figure 13 As shown, the sleeve 11 is provided with an outer mounting circle 1101 for the sleeve and the receiver, and a circumferential anti-rotation surface 1103. The sleeve 11 and the receiver are interference-fitted with the sleeve mounting hole and the rotation is restricted. The sleeve is also provided with a symmetrical head locking force surface 1102 inside. The head locking force surface 1102 cooperates with the head locking teeth to bear the gunpowder pressure at the moment of ammunition firing after locking.

[0055] like Figure 14As shown, the proximity switch 12 has a mounting thread 1201 at its front end, and a set nut 1202 is installed in the middle of the thread, which is connected and fixed to the first proximity switch mounting thread hole 104 and the second proximity switch mounting thread hole 105 at the front and rear ends of the housing. When the transmission nut 3 moves back and forth along the lead screw 2 in the housing frame mounting groove 101, when the transmission nut 3 blocks the tip of the proximity switch 12 on the movement path, the feedback signal causes the servo motor 13 to stop rotating, thereby stopping the movement of the frame 4.

[0056] like Figure 15 As shown, the output shaft of the servo motor 13 is provided with a second gear mounting position 1301, and the front end face is also provided with four motor mounting threaded holes 1302 for connecting with the motor base.

[0057] like Figure 16 As shown, the clamping block 14 is provided with two mounting holes 1401 for riveting and fixing to the clamping block mounting holes 103 on the side of the casing; it is also provided with an anti-rotation clamping block downward pressing slope 1402. After the anti-rotation clamping block comes into contact with it, the anti-rotation clamping block will be released from the restriction of the anti-rotation clamping block on the tenon of the machine head.

[0058] like Figure 14 As shown, the anti-rotation clamp is provided with a contact part 1501 with the clamp pressure block, a clamp support spring force-bearing part 1502, a shaft mounting hole 1503, and a contact part 1504 with the machine head tenon.

[0059] Work process:

[0060] The initial state of the firing control mechanism of the electric firing gun is as follows: the automatic mechanism assembly is at the rear of the receiver, the bolt head and bolt frame are in the unlocked state, the drive motor rotates and drives the bolt frame forward through the gear reversing linkage screw, the bolt head is restricted from rotating by the bolt frame and the anti-rotation catch, and moves forward with the bolt frame. When the bolt head moves into the sleeve and pushes the bullet into the chamber, the bolt frame then moves to the anti-rotation catch block, the anti-rotation catch block presses down the anti-rotation catch, the other end of the anti-rotation catch is raised, the bolt head tenon is no longer restricted by the anti-rotation catch, and begins to rotate in the bolt frame's locking and unlocking spiral groove to complete the locking, the bolt head locking teeth are fully engaged in the sleeve. After the bolt frame's action part triggers the front proximity switch, the drive motor stops rotating, and the bolt frame stops moving. At the same time, the firing pin is caught by the sear of the firing mechanism assembly, and the firing pin spring is compressed to store energy. At this time, the safety lever is manually rotated 90° so that the plane of the safety lever is aligned with the plane of the sear seat. Under the fire control drive, the servo drives the variable diameter cam to rotate at a predetermined angle, which pushes the firing lever upward. The firing lever is disengaged from the sear seat. Then, under the action of the firing pin spring force, the sear and the sear seat flip downward together, and the firing pin strikes the primer of the bullet in the chamber to complete the projectile firing.

[0061] The drive motor reverses, and the machine frame begins to move backward. Under the action of the machine frame's locking and unlocking spiral groove, the machine head unlocks and unscrews from the locking teeth of the sleeve. The machine head and machine frame move backward. When the anti-rotation catch is no longer resisted by the anti-rotation catch block, the other end of the anti-rotation catch presses down under the action of the anti-rotation catch, restricting the machine head tenon between the machine frame's locking groove and the anti-rotation catch. The machine frame and machine head continue to move backward, passing the stop iron. When the sensing part of the machine frame activates the rear proximity switch, the drive motor stops rotating, and the machine frame stops at the rearmost position, i.e., the starting position. The entire cycle is completed.

[0062] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.

Claims

1. A firing control mechanism for an electric firing pistol, comprising a receiver, a sleeve fixed inside the receiver, and a frame that can slide back and forth. A head and a tail are mounted inside the frame. The sleeve is located in front of the head. The head has a tenon, and the frame has a spiral surface. The tenon slides against the spiral surface, allowing the head to move spirally along the spiral surface and follow the frame to complete opening and closing actions. A firing pin and a firing pin spring are mounted inside the head, the spring being fitted onto the firing pin. The rear end of the firing pin is circumferentially limited by the tail. The mechanism is characterized in that: The firing pin has a firing pin catch ramp at its tail. A transmitter assembly is mounted below the receiver, including a transmitter housing. Inside the transmitter housing are a safety, a sear, and a firing lever. The safety is rotatable and is rod-shaped with a locating recess on its circumference. The transmitter housing contains a safety pin and a pin spring. The safety pin, under the force of the pin spring, abuts against the locating recess on the safety, providing elastic positioning and locking the safety in its open or closed state. The safety has a cut-shaped flat surface. The sear is inverted L-shaped, with its corner hinged to the transmitter housing. The surface of the sear corresponding to the safety is the sear seat. The sear is hinged to the other side of the sear base. The sear is unidirectionally positioned on the sear base and can rotate unidirectionally, allowing the firing pin to move backward to complete the firing pin mounting. During firing pin mounting, the firing pin mounting ramp is normally in contact with the sear. When the circumferential surface of the safety device is facing the sear base's working surface, the safety device is in the closed state, restricting the rotation of the sear base. When the flat surface on the safety device is facing the sear base's working surface, the safety device is in the open state, allowing the sear base to rotate and the firing pin mounting ramp to disengage from the sear. A torsion spring is provided on the lower side of the sear base, acting on the sear. Under the force of the torsion spring, the sear and the sear base can rotate upward together to reset. The firing lever is hinged to the launcher housing. A firing torsion spring is installed between the firing lever and the launcher housing. Under the action of the firing torsion spring, one end of the firing lever normally contacts the working surface of the sear seat, restricting the rotation of the sear seat and thus restricting the firing pin from disengaging and firing. A servo motor is installed on one side of the launcher housing. The servo motor's shaft is connected to a variable diameter cam, which is located inside the launcher housing. The servo motor can drive the variable diameter cam to push open the firing lever. After the firing lever rotates, it disengages from the working surface of the sear seat. Under the action of the firing pin spring force, the sear rotates and moves to make room, allowing the firing pin to disengage from the sear and slide forward to complete the firing action. The housing contains a rotatable lead screw, on which a servo motor is mounted. The lead screw and servo motor are connected via a gear set. A transmission nut is threaded onto the lead screw, and its lower end is fixedly connected to the frame, allowing the servo motor to drive the frame to slide back and forth. An anti-rotation catch is hinged to one side of the frame. One end of the anti-rotation catch is supported by an anti-rotation catch spring, while the other end, under the action of the anti-rotation catch spring, restricts the machine head to one end of the machine head helical surface on the frame, preventing relative movement between the machine head and the frame. The end of the housing corresponding to the anti-rotation catch is fitted with an anti-rotation catch spring. The device is equipped with a locking block, and one end of the locking block corresponding to the anti-rotation locking block has an anti-rotation locking block downward pressure slope. The bolt carrier drives the bolt head to slide forward and complete the feeding action. During the sliding of the bolt carrier, the firing pin spring is compressed and stores energy. After the bolt head enters the sleeve, the anti-rotation locking block contacts the anti-rotation locking block downward pressure slope, causing the end of the anti-rotation locking block with the anti-rotation locking block spring to press down. The anti-rotation locking block spring is compressed, the anti-rotation locking block opens, and the restriction on the bolt head is released. The bolt head rotates back to lock and feed the bullet into the chamber. After the bolt head rotates back and locks, the firing pin catch slope is engaged with the sear of the firing mechanism component, and the firearm is ready to fire.

2. The firing control mechanism for an electric firing gun according to claim 1, characterized in that: The servo motor and gear set are installed at the rear end of the casing. The size of the two gears in the gear set is selected according to the reduction ratio.

3. The firing control mechanism for an electric firing gun according to claim 1, characterized in that: Proximity switches are installed at the front and rear ends of one side of the casing. The two proximity switches control the maximum travel range of the frame. When the frame moves back and forth, if the transmission nut blocks the tip of one of the proximity switches, the proximity switch sends a feedback signal, causing the servo motor to stop rotating, thereby stopping the frame from moving.

4. The firing control mechanism for an electric firing gun according to claim 1, characterized in that: The casing is equipped with a frame mounting slot, in which the frame slides and is circumferentially limited.

5. The firing control mechanism for an electric firing gun according to claim 1, characterized in that: The transmitter component mounting notch and the transmitter component threaded mounting hole are provided at the bottom of the casing; a positioning duckbill is provided at the front of the transmitter box, which engages with the transmitter component mounting notch; a screw through hole is provided at the rear of the transmitter box, which is fixed to the transmitter component threaded mounting hole by a screw.

6. The firing control mechanism for an electric firing gun according to claim 1, characterized in that: An anti-rotation clamp mounting part is provided on one side of the frame. The anti-rotation clamp mounting part includes mutually perpendicular anti-rotation clamp support spring mounting holes and anti-rotation clamp shaft pin holes. The middle part of the anti-rotation clamp is hinged to the anti-rotation clamp shaft pin holes via a shaft. The anti-rotation clamp has a contact part with the clamp pressure block, a force-bearing part with the clamp support spring, and a contact part with the machine head tenon. The contact part with the machine head tenon is located at one end of the anti-rotation clamp, while the contact part with the clamp pressure block and the force-bearing part with the clamp support spring are arranged opposite to each other and are all located at the other end of the anti-rotation clamp. An anti-rotation clamp support spring is installed in the anti-rotation clamp support spring mounting hole. The anti-rotation clamp support spring acts on the force-bearing part of the clamp support spring, so that the contact part with the machine head tenon is normally engaged with the machine head tenon.

7. The firing control mechanism for an electric firing gun according to claim 1, characterized in that: The front end of the bolt head is symmetrically equipped with bolt head locking teeth on both sides, and the inside of the sleeve is symmetrically equipped with bolt head locking force-bearing surfaces on both sides. The end face of the bolt head tenon is equipped with a part that interacts with the anti-rotation catch. When the anti-rotation catch is in the restricted state, the part that interacts with the anti-rotation catch restricts the bolt head from sliding along the bolt head spiral surface. When the anti-rotation catch is not restricted, the bolt frame can push the bolt head, and the bolt head slides spirally along the bolt head spiral surface. Then, the bolt head locking teeth enter the bolt head locking force-bearing surface of the sleeve and complete the rotation locking, bearing the gunpowder pressure at the moment of ammunition firing after locking.

8. The firing control mechanism for an electric firing gun according to claim 1, characterized in that: The tail section has a firing pin mounting ramp groove along the axis at the rear end of the machine to guide and allow the firing pin to strike forward; the tail section has a firing pin mounting hole inside; the middle of the tail section has a firing pin spring limiting surface, which contacts and limits the firing pin spring at the tail end, so that the firing pin spring is in a pre-compressed state and stores energy for the firing pin.

9. The firing control mechanism for an electric firing gun according to claim 1, characterized in that: The front of the tail section is symmetrically equipped with limiting bosses, which are assembled with the tail mounting position at the tail of the frame to restrict the tail section to the tail of the frame. The middle of the tail section is also equipped with an anti-rotation notch, which uses a pin to restrict the circumferential rotation of the tail section.
