In an alternative embodiment, the first driving mechanism 170 includes a first driving source 171, a transmission mechanism, and a first transmission shaft, where the first driving source 171 is disposed on the first bolt carrier 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 carrier 140, the first transmission shaft is rotatably connected to the first bolt carrier 130, the first bolt carrier 130 is provided with a second through hole through which the first transmission shaft passes, and the first transmission shaft is rotatably matched with the second through hole. The contact area between the inner surface of the second through hole and the first transmission shaft is larger, namely, the surface contact is performed, so that the friction between the first bolt carrier 130 and the first transmission shaft is larger, and the transmission efficiency is lower. Thus, optionally, the first driving mechanism 170 may further include a first bearing 175, where the first transmission shaft is rotatably connected to the first bolt carrier 130 through the first bearing 175, and the first transmission shaft may rotate relative to the first bolt carrier 130 through the first bearing 175, so as to drive the second bolt carrier 140 to rotate. The first bearing 175 can make the friction force between the first transmission shaft and the first bolt carrier 130 smaller, i.e. point contact, so that the transmission efficiency is higher, and the stability of the first transmission shaft during rotation is improved.

Alternatively, the transmission mechanism may include a first driving wheel 172, a first driven wheel 173, and a first flat belt, where 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 drives, 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 carrier 140 to rotate, thereby driving the bolt camera 160 to rotate. The first flat belt is driven by friction with the first driving pulley 172 and the first driven pulley 173, so that slippage occurs between the first flat belt and the first driving pulley 172 and the first driven pulley 173, thereby preventing accurate rotation of the bolt camera 160. Thus, in another embodiment, the first driving mechanism 170 may further include a first synchronous belt 174, where the first synchronous belt 174 is engaged with the first driving wheel 172 and the first driven wheel 173, respectively. The first timing belt 174 may synchronize 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 pressing plate 177, a first bearing washer 178 and a first clamping spring 179, and the first driven wheel fixing end cover 176, the first bearing pressing plate 177, the first bearing washer 178 and the first clamping 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 press plate 177 can secure the first bearing 175 to the first bolt carrier 130 to prevent the first bearing 175 from falling out. The first bearing washer 178 may prevent the first snap spring 179 from contacting the first bearing 175, helping to protect the first bearing 175 from damage. The first snap spring 179 may be used to prevent the first drive shaft from falling off of the first bolt carrier 130.

Since the first synchronous belt 174 is meshed 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 synchronous belt 174, the first driven wheel 173 will excessively rotate, which is not beneficial to improving the rotation precision of the camera 160. To solve this 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, and the resistance member 180 is located between the first bolt carrier 130 and the second bolt carrier 140, and the resistance member 180 presses the first bolt carrier 130. Pressing the first bolt carrier 130 by the resistance member 180 increases the friction between the resistance member 180 and the first bolt carrier 130, thereby slowing down the rotation of the second bolt carrier 140 to counteract the rotation error of the first driven wheel 173, thereby facilitating the improvement of the rotation accuracy of the bolt camera 160.

In order to increase the friction between the drag 180 and the first bolt carrier 130, the drag 180 may also be provided with a protrusion that is oriented toward the first bolt carrier 130 and that extends obliquely in a direction away from the second bolt carrier 140. The oblique extension of the protrusions may be opposite to the direction of rotation of the second bolt carrier 140 to prevent the drag 180 from being too worn by friction. The provision of the protrusions reduces the contact area between the drag member 180 and the first bolt carrier 130, thereby increasing the friction therebetween, which is advantageous for further improving the rotational accuracy of the bolt camera 160.

In one embodiment, the first drive source 171 is fixedly coupled to the first bolt carrier 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. Therefore, in another embodiment, the first driving source 171 is rotatably connected to the first bolt carrier 130, and the first driving source 171 has a space between the rotation axis of the first bolt carrier 130 and the axis of the first output shaft. The camera may further include a first tensioning mechanism 190, one end of the first tensioning mechanism 190 being connected to the first bolt carrier 130, and the other end of the first tensioning mechanism 190 being connected to the first drive source 171 to put the first timing belt 174 under tension. In this embodiment, since the first driving source 171 is rotatably connected to the first bolt carrier 130, the first tensioning mechanism 190 can change the distance between the first driving wheel 172 and the first driven wheel 173, so that the first synchronous belt 174 can be more easily installed, and after the first synchronous belt 174 is installed, the first driving source 171 is fixed to the first bolt carrier 130 by the first fastening member, and this way is beneficial to increasing the engagement area of the first synchronous belt 174 with the first driving wheel 172 and the first driven wheel 173, so that the engagement transmission of the first synchronous belt 174 with the first driving wheel 172 and the first driven wheel 173 is more beneficial.

In an alternative embodiment, the first tensioning mechanism 190 may include a first flexible member having one end connected to the first drive source 171 and the other end wound around the first bolt carrier 130.

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 camera 160 is rotatably disposed on the second camera bracket 140, the second driving wheel 202 drives the second driving wheel 203 to rotate around the axis of its second driven wheel 203 through the second flat belt and the second driven wheel 203, and finally the second driving wheel 202 drives the camera 160 to rotate. The second flat belt is driven by friction 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, thereby being unfavorable for the accurate rotation of the camera 160. Therefore, in another embodiment, the second driving mechanism 200 may further include a second synchronous belt 204, where the second synchronous belt 204 is meshed with the second driving wheel 202 and the second driven wheel 203, respectively, that is, the second driving wheel 202 is connected to the second driven wheel 203 through the second synchronous belt 204.

In an alternative embodiment, the second driving mechanism 200 may further include a second transmission shaft 208, where one end of the second transmission shaft 208 is fixedly connected to the second driven wheel 203, the other end of the second transmission shaft 208 is fixedly connected to the second bolt carrier 140, and the mounting bracket 162 is provided with a third through hole through which the second transmission shaft passes, and the second transmission shaft is in rotation fit with the third through hole. Because the contact area between the inner surface of the third through hole and the second transmission shaft is larger, that is, the surface contact is performed, the friction between the mounting bracket 162 and the second transmission shaft is larger, and the transmission efficiency is lower. Thus, in an alternative embodiment, the second drive mechanism 200 may further include a second bearing 205, and the mounting bracket 162 is rotatably coupled to the second drive shaft 208 via the second bearing 205. The second driving wheel 202 rotates around the axis of the second driven wheel 203 to drive the second driving source 201 to rotate, and then the second driving source 201 drives the mounting bracket 162 to rotate. The mounting bracket 162 may be rotated relative to the second drive shaft 208 by the second bearing 205, thereby rotating the bolt face camera 160 relative to the second bolt face bracket 140. The second bearing 205 may provide less friction, i.e., point contact, between the second drive shaft 208 and the mounting bracket 162, resulting in greater drive efficiency and improved stability in rotation of the bolt face camera 160.

The photocell 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. In this embodiment, since the distance between the second driving pulley 202 and the second driven pulley 203 is fixed, it is not easy to install the second timing belt 204. Therefore, in another embodiment, the second driving source 201 is rotatably connected to the mounting bracket 162, and there is a space between the axis of rotation of the second driving source 201 relative to the mounting bracket 162 and the axis of the second output shaft.

In this embodiment, since the second driving source 201 is rotatably connected to the mounting bracket 162, the second tensioning mechanism 210 can change the distance between the second driving wheel 202 and the second driven wheel 203, so that the second synchronous belt 204 can be more easily installed, and after the second synchronous belt 204 is installed, the second driving source 201 is fixed to the mounting bracket 162 by the second fastener, and this way is beneficial to increasing the engagement area of the second synchronous belt 204 with the second driving wheel 202 and the second driven wheel 203, so that the engagement transmission of the second synchronous belt 204 with the second driving wheel 202 and the second driven wheel 203 is more beneficial.

In an alternative embodiment, the second tensioning mechanism 210 may include a second flexible member, one end of which is connected to the second driving source 201, and the other end of which is wound around the housing 161 and/or the mounting bracket 162.

In this embodiment, the casing 161 and the second bolt carrier 140 need to be provided with a plurality of through holes, which is not beneficial to ensuring the tightness of the camera. Therefore, in another embodiment, the third transmission shaft 420 is provided with a first through hole, that is, the third transmission shaft 420 is a hollow shaft, and the electrical connection wire 240 is disposed through the first through hole. The first through hole can communicate the space in the housing 161 and the space in the second bolt carrier 140, but not directly communicate with the external environment, so that the tightness of the camera can be ensured by penetrating the electrical connection wire 240 into the first through hole, and the layout of the electrical connection wire 240 is more facilitated.

In an alternative embodiment, the electrical connection wire 240 is subject to friction with the third drive shaft 420 as the bolt face camera 160 rotates relative to the second bolt face carrier 140, thereby easily causing wear to the electrical connection wire 240.
