The main body 1 of the jig is also provided with a limiting hole 12 spaced from the positioning hole 11 at a certain distance. The rotating claw 2 is pivotally connected to the jig body 1 , and the two ends of the torsion spring 3 abut the jig body 1 and the rotating claw 2 respectively.

The locking lever 5 is movably sleeved with the rotating claw 2 , so that the locking lever 5 can move along the length direction of the locking lever 5 . Two ends of the first elastic member 4 are respectively connected to the fixture body 1 and the rotating claw 2 , and the first elastic member 4 is used to drive the locking rod 5 to be inserted into the limiting hole 12 .

When the camera 7 is processed or detected, that is, when the camera 7 is positioned and fixed by the camera fixing jig, the camera fixing jig can be unlocked by manually pulling the locking lever 5 . Specifically, after the locking lever 5 is manually pulled, the locking lever 5 protrudes from the limiting hole 12 , and the rotational interference of the limiting hole 12 on the rotating claw 2 is released, so that the rotating claw 2 at this time can be opposed to each other. Rotate on the jig main body 1. Wherein, since the locking rod 5 is movably sleeved with the rotating claw 2, the locking rod 5 continues to move relative to the rotating claw 2 so that the locking rod 5 or the first elastic member 4 can exert a pressing force on the rotating claw 2, so that the The rotating claw 2 rotates against the elastic force of the torsion spring 3, that is, the unlocking of the camera fixing jig is realized. After unlocking, since the rotating claw 2 rotates, the rotating claw 2 will not interfere with the installation of the camera 7 into the positioning hole 11. After positioning the camera 7 through the positioning hole 11; Under the action, the rotating claw 2 rotates relative to the fixture body to reset, and squeezes the camera 7 into the positioning hole 11 .

The locking rod 5 is movably sleeved with the rotating claw 2, and the first elastic member 4 drives the locking rod 5 to move along its own length direction, so that the locking rod 5 can be inserted into the limiting hole 12 of the fixture body 1, Then, the rotation of the locking rod 5 is limited by the limiting hole 12, and finally the rotation of the rotating claw 2 is limited when the locking rod 5 cooperates with the limiting hole 12; to ensure that the camera 7 fixing fixture is free of air cylinders and hydraulic cylinders. The camera 7 can be stably positioned and fixed under the action of the high-pressure tool. Moreover, as long as the locking lever 5 is released from the limiting hole 12 during the unlocking process, the rotation of the rotating claw 2 can be realized, so that the camera 7 can be taken out from the positioning hole 11; It can be disassembled, and the operation process is simple and convenient. Furthermore, since the camera fixing fixture has a simple structure and a power mechanism is omitted, the manufacturing cost is greatly reduced.

Preferably, the rotating claw 2 is provided with a blind hole 21 , the first elastic member 4 and the locking rod 5 are located in the blind hole 21 , and both ends of the first elastic member 4 abut against the bottom of the blind hole 21 and the locking rod respectively. rod 5. In this way, the locking rod 5 can be located in the concealed space protected by the blind hole 21, and the first elastic member 4 is also located in the concealed space, thereby greatly reducing the failure of the first elastic member 4 and the locking rod 5, resulting in probability of damage, etc. Moreover, the blind hole 21 can reliably guide and limit the first elastic member 4 , thereby further ensuring the normal reset of the locking rod 5 . The connection relationship between the first elastic member 4 and the bottom of the blind hole 21 may be a fixed connection or a detachable abutment; the connection relationship between the first elastic member 4 and the locking rod 5 may also be Fixed connection or detachable abutment. Obviously, in this embodiment, as a preferred implementation, the blind hole 21 is movably connected to the locking rod 5 (that is, the rotating claw 2 is movably connected to the locking rod 5). In addition to this arrangement, the blind hole 21 can also be arranged on the locking rod 5, and the rotating claw 2 is provided with a guide column (a cylindrical or square column or irregular cylinders).

That is, the button 23 can move along the axial direction of the through hole 22, so as to squeeze the locking rod 5 and move the locking rod 5, thereby realizing the separation of the locking rod 5 and the limit block. 23 When the locking lever 5 is further squeezed, the locking lever 5 can continue to be pressed, so that the locking lever 5 or the first elastic member 4 squeezes the rotating claw 2 and makes the rotating claw 2 relative to the fixture body. 1 rotate, so as to realize the quick installation and disassembly of the camera 7. Wherein, in addition to the translational squeezing of the locking rod 5 by the button 23, a knob can also be arranged in the through hole 22, and the knob can be set as a cam structure, and the locking rod 5 can also be driven to compress the first elastic member 4, so as to rotate The claw 2 rotates relative to the fixture body. In addition, according to the positional relationship between the axis of the through hole 22 and the axis of the blind hole 21, the button 23 can also be flexibly arranged, so that the button 23 can easily drive the locking rod 5 to squeeze the first elastic member 4 and release the limit Hole 12; for example, the axis of the through hole 22 is not perpendicular to the axis of the blind hole 21 but is inclined at a certain angle. At this time, if the button 23 squeezes the locking rod 5 along the axial direction of the through hole 22, the locking rod 5 It is sufficient to squeeze the first elastic member 4 . However, this setting method is difficult to process, and from the viewpoint of ease of manufacture of the camera fixing jig, as a preferred embodiment, the axis of the through hole 22 and the axis of the blind hole 21 are perpendicular to each other.

Further, in order to facilitate the automatic reset of the button 23, it is convenient to press the button 23 repeatedly.

Obviously, this arrangement is more convenient for the human hand to press the button 23 . The inclined surface 232 may be a plane or a curved surface. In this embodiment, the inclined surface 232 is a conical surface.

Preferably, the camera fixing jig further includes a rotating shaft 6, the axis of the rotating shaft 6 is perpendicular to the axis of the positioning hole 11 and spaced at a certain distance, and both ends of the rotating shaft 6 abut and connect the rotating claw 2 and the jig main body 1 respectively, and the rotating claw 2 At least one of the jig main body 1 is pivotally connected to the rotating shaft 6 . It can be understood that the rotating shaft 6 can belong to the rotating claw 2 itself or a part of the fixture body 1 itself, or the rotating shaft 6 can also be a separate part; as long as the rotating shaft 6 is used as an intermediate connection carrier, it is ensured that the rotating claw 2 can be It can be rotated relative to the jig main body 1 . As an alternative, the rotating shaft 6 can also be replaced by a spherical concave surface and a spherical convex surface, that is, one of the rotating claw 2 and the fixture body 1 is provided with a spherical concave surface, and the other is provided with a spherical convex surface, so as to realize both the rotational connection.

Obviously, on the basis of setting the rotating shaft 6, in order to make the connection of the torsion spring 3 reliable, in addition to fixing the two ends of the torsion spring 3 (such as welding, gluing, bundling, socket fixing, etc.) On the main body 1. As a more preferred embodiment, the torsion spring 3 is sleeved on the rotating shaft 6; this arrangement not only facilitates the quick completion of the fixing and installation of the torsion spring 3, but also the torsion spring 3 cannot escape the limit of the rotating shaft 6 even if it fails. , the limit method is more reliable. Moreover, because the socket connection is relatively firm, the two ends of the torsion spring 3 can abut the rotating claw 2 and the fixture body 1 respectively, and there is no need to further complete the process of fixing the two ends of the torsion spring 3, which reduces the fixation of the camera. The production difficulty of the fixture.
