In an alternative embodiment, the first driving mechanism 170 includes a first driving source 171, a transmission mechanism, and a first transmission shaft, the first driving source 171 is disposed on the first bolt support 130, the transmission mechanism is connected to the first driving source 171, one end of the first transmission shaft is fixedly connected to the transmission mechanism, the other end of the first transmission shaft is fixedly connected to the second bolt support 140, the first transmission shaft is rotatably connected to the first bolt support 130, the first bolt support 130 is provided with a second through hole for the first transmission shaft to pass through, and the first transmission shaft is rotatably matched to the second through hole. Because the internal surface of second through-hole and the area of contact of first transmission shaft is great, face contact promptly to make the friction of first rifle bolt support 130 and first transmission shaft great, and then lead to transmission efficiency to be lower. Therefore, optionally, the first driving mechanism 170 may further include a first bearing 175, and the first transmission shaft is rotatably connected to the first bolt support 130 through the first bearing 175, and the first transmission shaft may rotate relative to the first bolt support 130 through the first bearing 175, so as to rotate the second bolt support 140. The first bearing 175 can make the friction between the first transmission shaft and the first bolt support 130 smaller, i.e., point contact, the transmission efficiency is higher, and it is advantageous to improve the stability of the first transmission shaft when rotating.

Alternatively, the transmission mechanism may include a first driving wheel 172, a first driven wheel 173, and a first flat belt, the first driving wheel 172 is sleeved on the first output shaft of the first driving source 171, the first driving wheel 172 is connected to the first driven wheel 173 through the first flat belt, and the first driven wheel 173 is connected to the second bolt carrier 140. When the first driving source 171 is driven, the first output shaft of the first driving source 171 drives the first driving wheel 172 to rotate, then the first driving wheel 172 drives the first driven wheel 173 to rotate through the first flat belt, and finally the first driven wheel 173 drives the second bolt support 140 to rotate, so as to drive the bolt camera 160 to rotate. The first flat belt is in frictional communication with the first driving pulley 172 and the first driven pulley 173, and thus slippage between the first flat belt and the first driving pulley 172 and the first driven pulley 173 occurs, which is disadvantageous to the accurate rotation of the bolt camera 160. Therefore, in another embodiment, the first driving mechanism 170 may further include a first timing belt 174, and the first timing belt 174 is engaged with the first driving pulley 172 and the first driven pulley 173, respectively. The first timing belt 174 may synchronize the movement between the first drive pulley 172 and the first driven pulley 173 to facilitate accurate rotation of the bolt face camera 160.

In an alternative embodiment, the first driving mechanism 170 may further include a first driven wheel fixing end cover 176, a first bearing plate 177, a first bearing washer 178 and a first snap spring 179, and the first driven wheel fixing end cover 176, the first bearing plate 177, the first bearing washer 178 and the first snap spring 179 are all sleeved on the first transmission shaft. The first driven wheel 173 may be secured to the first drive shaft by a first driven wheel securing end cap 176. The first bearing plate 177 may fix the first bearing 175 to the first bolt support 130 to prevent the first bearing 175 from falling off. The first bearing washer 178 prevents the first clamp spring 179 from contacting the first bearing 175, and is advantageous for protecting the first bearing 175 from damage. The first snap spring 179 may be used to prevent the first drive shaft from falling off the first bolt face support 130.

Since the first timing belt 174 is engaged with the first driving wheel 172 and the first driven wheel 173, when the first driving wheel 172 drives the first driven wheel 173 to rotate through the first timing belt 174, the first driven wheel 173 may rotate excessively, which is not favorable for improving the rotation accuracy of the bolt camera 160. In order to solve the problem, the camera may further include a resistance member 180, the resistance member 180 is a wave washer, the resistance member 180 is sleeved on the first transmission shaft, the resistance member 180 is located between the first bolt support 130 and the second bolt support 140, and the resistance member 180 presses the first bolt support 130. The resistance 180 pressing on the first bolt face support 130 can increase the friction between the resistance 180 and the first bolt face support 130, so that the rotation of the second bolt face support 140 can be slowed down, the rotation error of the first driven wheel 173 can be offset, and the rotation accuracy of the bolt face camera 160 can be improved.

To increase the friction between the resistance 180 and the first bolt face support 130, the resistance 180 may also be provided with a protrusion that faces the first bolt face support 130 and that extends obliquely in a direction away from the second bolt face support 140. The protrusions may extend obliquely in a direction opposite to the rotation direction of the second bolt face support 140 to prevent the resistance member 180 from being worn too much due to friction. The contact area between the resistance piece 180 and the first bolt face support 130 can be reduced by arranging the protrusion, so that the friction force between the resistance piece and the first bolt face support 130 can be increased, and the rotation precision of the bolt face camera 160 can be further improved.

In one embodiment, the first drive source 171 is fixedly coupled to the first bolt face support 130. In this embodiment, since the distance between the first driving pulley 172 and the first driven pulley 173 is fixed, it is not easy to install the first timing belt 174.

When the second driving source 201 drives, the second output shaft of the second driving source 201 drives the second driving wheel 202 to rotate, and since the bolt camera 160 is rotatably disposed on the second bolt support 140, the second driving wheel 202 is driven by the second flat belt and the second driven wheel 203 to rotate around the axis of the second driven wheel 203, and finally the second driving wheel 202 drives the bolt camera 160 to rotate. The second flat belt is in friction transmission with the second driving pulley 202 and the second driven pulley 203, so that the second flat belt slips with the second driving pulley 202 and the second driven pulley 203, which is not favorable for accurate rotation of the bolt camera 160. Therefore, in another embodiment, the secondary driving mechanism 200 may further include a secondary timing belt 204, and the secondary timing belt 204 is engaged with the secondary driving pulley 202 and the secondary driven pulley 203 respectively, i.e., the secondary driving pulley 202 is connected to the secondary driven pulley 203 through the secondary timing belt 204.

Because the contact area of the inner surface of the third through hole and the second transmission shaft is large, namely, the inner surface of the third through hole is in surface contact with the second transmission shaft, the friction between the mounting bracket 162 and the second transmission shaft is large, and the transmission efficiency is low. Therefore, in an alternative embodiment, the second driving mechanism 200 may further include a second bearing 205, and the mounting bracket 162 is rotatably connected to the second transmission shaft 208 through the second bearing 205. When the second driving wheel 202 rotates around the axis of the second driven wheel 203, the second driving source 201 is driven to rotate, and then the second driving source 201 drives the mounting bracket 162 to rotate. The mounting bracket 162 may rotate relative to the second drive shaft 208 via the second bearing 205, thereby causing the bolt face camera 160 to rotate relative to the second bolt face bracket 140. The second bearing 205 may enable less friction between the second transmission shaft 208 and the mounting bracket 162, i.e., point contact, resulting in higher transmission efficiency and facilitating improved stability of the bolt face camera 160 during rotation.

The photoelectric panel 370 may be used to identify the angle of rotation of the bolt face camera 160.

In one embodiment, the second driving source 201 is fixedly connected to the mounting bracket 162.
