In order to enhance the smoothness of the sliding of the protrusion 20 along the first guide lug 1250 or the second guide lug 1252, the protrusion 20 includes an arc surface 20a, and the arc surface 20a of the protrusion 20 may be in contact with the first arc surface 1250a or the second arc surface 1252a, thereby further improving the smoothness of the guiding process. In addition, the inner surface of the recess 30 can be a tapered surface, which enables the protrusion 20 to be quickly positioned after sliding into the recess 30, and the positioning is accurate and the deviation is small.

The projection 20 further includes a flat surface 20b at the top, and the flat surface 20b can ensure that the first guide tab 1250 or the second guide tab 1252 is not scratched when being in contact with the first guide tab 1250 or the second guide tab 1252.

In one embodiment, the first guide lug 1250 and the second guide lug 1252 are symmetrically distributed up and down about the center of the recess 30. The first guide lug 1250 and the second guide lug 1252 which are symmetrically arranged have the same external dimension and the same contact degree with each convex part 20, so that the consistency of guiding is improved.

Although the embodiment in which the joint bracket 12 includes the recess 30 is described above, it should be understood that in some other embodiments, the main bracket 11 may include the recess 30, and the guide ear 125 may be disposed on the recess 30 of the main bracket 11, which will not be described herein.

Referring to fig. 2 and fig. 3, the main body frame 11 further includes at least two sliding columns 112, and the specific number of the sliding columns 112 is not limited, and may be two or more than two.

The adaptor bracket 12 includes an equipment mounting portion 120 and at least two sliding portions 122 connected to the equipment mounting portion 120. The apparatus mounting portion 120 is opened with an apparatus mounting hole 1200, and the photographing apparatus 20 is fixedly assembled through the apparatus mounting hole 1200 of the apparatus mounting portion 120. The sliding portion 122 is slidably sleeved on the corresponding sliding column 112. The number of the sliding portions 122 is not limited, and may be two or more, and the configuration may be selected according to the number of the sliding columns 112. The adaptor bracket 12 is movable to any one of a plurality of mounting positions with respect to the main body bracket 11 by the sliding of the sliding portion 122 along the slide post 112. As can be seen from the above description, the sliding fit between the at least two sliding portions 122 and the at least two sliding columns 112 defines the track of the adaptor bracket 12 when moving between the plurality of mounting positions, reduces the risk of tilting of the adaptor bracket 12 when moving, improves the balance and smoothness of the adaptor bracket 12 during moving, and reduces the probability of jamming of the adaptor bracket 12 when moving.

In one embodiment, the at least two spools 112 include a first spool 112a and a second spool 112b, and the equipment relief port 110c includes a relief port first side 110ca and a relief port second side 110cb opposite the relief port first side 110 ca. The first sliding pillar 112a is located on the yielding port first side 110ca of the device yielding port 110c, and the second sliding pillar 112b is located on the yielding port second side 110cb of the device yielding port 110 c. Correspondingly, the at least two sliding portions 122 include a first sliding portion 122a and a second sliding portion 122b, the equipment mounting portion 120 includes a mounting portion first side 120a and a mounting portion second side 112b opposite the mounting portion first side 120a, the first sliding portion 122a is disposed on the mounting portion first side 120a, and the second sliding portion 122b is disposed on the mounting portion second side 122 b. The receding opening first side 110ca and the mounting portion first side 120a are located on the same side, and the receding opening second side 110cb and the mounting portion second side 112b are located on the same side. The first sliding portion 122a is slidably disposed on the first sliding column 112a, and the second sliding portion 122b is slidably disposed on the second sliding column 112 b. In this embodiment, the first sliding pillar 112a and the second sliding pillar 112b are respectively located at two opposite sides of the periphery of the equipment clearance 110, so that the sliding smoothness can be ensured through the sliding pillars 112 and the sliding portions 122 from the two opposite sides, the risk of inclination occurring when the transfer bracket 12 moves can be effectively reduced, and the risk of offset locking in the front-back and left-right directions during the movement can be effectively reduced.

In one embodiment, the first and

second spools

112a and 112b may be aligned on opposite sides of the equipment docking port 110. In another embodiment, the first and

second spools

112a and 112b are offset from each other in the extending direction (Y direction in fig. 2) of the offset opening first side 110 ca. The device relief port 110c includes a relief port third side 110cc connecting the relief port first side 110ca and the relief port second side 110cb, and a distance between the first spool 112a and the relief port third side 110cc is not equal to a distance between the second spool 112b and the relief port third side 110cc, such that the first spool 112a and the second spool 112b are offset along an extending direction of the relief port first side 110 ca. Accordingly, the first sliding portion 122a and the second sliding portion 122b are disposed to be offset in the extending direction of the mounting portion first side 110 a. The device mounting portion 120 includes a mounting portion third side 120c connecting the mounting portion first side 120a and the mounting portion second side 120b, and a distance between the first sliding portion 122a and the mounting portion third side 120c is not equal to a distance between the second sliding portion 122b and the mounting portion third side 120c, thereby causing the first sliding portion 122a and the second sliding portion 122b to be staggered in an extending direction (Y direction in fig. 3) of the mounting portion first side 120 a. After the displacement, the sliding fit positions of the first sliding column 112a and the first sliding portion 122a and the sliding fit positions of the second sliding column 112b and the second sliding portion 122b are displaced, so that the risk of lateral jamming in the extending direction of the first side 120a of the installation portion during movement is further reduced, the risk of offset jamming in the front-back left-right direction during movement is further reduced, and the risk of inclination of the adapter bracket 12 is further reduced.

Referring to fig. 9, fig. 9 is a schematic diagram of an embodiment of the first strut 112a in fig. 2. The second spool 112b is similar to the first spool 112 a.

The present application is not limited to the specific structure of the first spool 112a and/or the second spool 112 b. In one embodiment, the first spool 112a is a circular spool. In other embodiments, the first and/or second sliding

columns

112a, 112b may be semicircular sliding columns, elliptical sliding columns, prismatic sliding columns, but are not limited thereto.

Referring to fig. 10, fig. 10 is a schematic view of an embodiment of the first sliding portion 122a in fig. 3. The second sliding portion 122b is similar to the first sliding portion 122 a.

The present application does not limit the specific structure of the first sliding portion 122a and/or the second sliding portion 122 b. In one embodiment, the first sliding portion 122a includes a slide lug 1220 connected with the device mounting portion 120 and a slip ring 1222 connected with the slide lug 1220. The slide lug 1220 includes an upper end plate 1220a and a lower end plate 1220b spaced apart from and opposed to the upper end plate 1220a, the upper end plate 1220a and the lower end plate 1220b are provided with coaxial through holes 1220c, a slide ring 1222 extends between the upper end plate 1220a and the lower end plate 1220b, and a hollow portion of the slide ring 1222 communicates with the through holes 1220 c. The slip ring 1222 is extended from the upper end plate 1220a and the lower end plate 1220b of the sliding lug 1220, so that on one hand, the matching length of the first sliding portion 122a and the first sliding column 112b can be increased, and the smoothness of sliding can be improved; on the other hand, the deformation of the upper end plate 1220a and the lower end plate 1220b can also be reduced.

In one embodiment, the slip ring 1222 may be clampingly secured between the upper end plate 1220a and the lower end plate 1220 b. In another embodiment, the slip ring 1222 may be inserted into a through hole 1220c extending through the upper end plate 1220a and the lower end plate 1220 b. For example, one end of the slip ring 1222 is inserted into the through hole 1220c of the upper end plate 1220a, and the other end of the slip ring 1222 is inserted into the through hole 1220c of the upper end plate 1220a, so that the slip ring 1222 is prevented from forming a cantilever structure, thereby ensuring stability of the position of the slip ring 1222 itself. In one embodiment, the slide tab 1220 may be provided as a unitary structure with the device mounting portion 120, and the slide tab 1220 may be bent through a stamping process, but is not limited thereto. The second sliding portion 122b may have the same structure as the first sliding portion 122a, and will not be described herein.

In the above embodiment, the sliding mating surface of the first sliding column 112a and the first sliding portion 122a is a cylindrical surface. It should be noted that the sliding mating surface of the first spool 112a and the first sliding portion 122a is not limited to a cylindrical surface, and may be a flat surface. The sliding engagement surface between the second slider 112b and the second sliding portion 122b is not limited to a cylindrical surface, and may be a flat surface.

Referring to fig. 2 and 3 again, the main body support 11 further includes a sliding slot 116, and the sliding slot 116 extends from the back surface 110b of the main body 110 to a direction away from the front surface 110 a. In one embodiment, the slide channel 116 is located between the support portion 114 and the mounting portion 115. Accordingly, the adaptor bracket 12 includes a mating portion 124 connected to the equipment mounting portion 120, and the mating portion 124 slidably extends into the slide slot 116 along the slide slot 116. The sliding engagement direction of the engaging portion 124 with the slide groove 116 coincides with the sliding engagement direction of the slide post 112 with the sliding portion 122. It can be seen that by providing the engaging portion 124 to be slidably engaged with the slide groove 116, the slidably engaged portion between the adaptor bracket 12 and the main bracket 12 is further increased, so that the risk of the adaptor bracket 12 tilting when moving relative to the main bracket 11 is further reduced, and the smoothness of the adaptor bracket 12 when moving is improved.

The number of the sliding grooves 116 is not limited, and may be one or more. A plurality of chutes 116 may be spaced about the periphery of the equipment access opening 110 c. Accordingly, the number of the engaging portions 124 is not limited, and may be one or more, and a plurality of the engaging portions 124 may be distributed at intervals around the device mounting portion 120, and slidably engage with the corresponding sliding slots 116.

In the embodiment shown in fig. 2 and 3, the sliding slot 116 includes a first sliding slot 116a and a second sliding slot 116b, and the first sliding slot 116a is located on the first side 110ca of the slot and opens on the first support portion 1140. The second sliding slot 116b is located on the second side 110cb of the clearance opening and opens on the second supporting portion 1142. The mating portion 124 includes a first mating portion 124a and a second mating portion 124b, the first mating portion 124a being disposed on the mounting portion first side 120a, and the second mating portion 124b being disposed on the mounting portion second side 120 b. The first engaging portion 124a slidably extends into the first slide slot 116a, and the second engaging portion 124b slidably extends into the second slide slot 116 b. Therefore, the first sliding groove 116a and the second sliding groove 116b are respectively in sliding fit with the corresponding first matching portion 124a and the second matching portion 124b, so that the sliding fit positions are increased, the balance and smoothness of the rotatable bracket 12 in moving relative to the main body bracket 11 are improved, and the risk of blocking of inclination and lateral deviation of the rotatable bracket 12 is reduced.

In one embodiment, the first sliding slot 116a and the second sliding slot 116b are arranged in a staggered manner in the extending direction of the first side 110ca of the relief opening. That is, the distance between the first sliding groove 116a and the third side 110cc of the abdicating hole is not equal to the distance between the second sliding groove 116b and the third side 110cc of the abdicating hole, so that the first sliding groove 116a and the second sliding groove 116b are staggered along the extending direction of the first side 110ca of the abdicating hole. The first and

second engagement portions

124a and 124b are offset in the direction of extension of the mounting portion first side 120 a. That is, the distance between the first mating portion 124a and the third side 120c of the mounting portion is not equal to the distance between the second mating portion 124b and the third side 120c of the mounting portion, so that the first mating portion 124a and the second mating portion 124b are staggered along the extending direction of the first side 120a of the mounting portion. After staggering, compared with opposite alignment, the effect of preventing the adapter bracket 12 from inclining and being blocked by lateral deviation is further enhanced.

In one embodiment, the first runner 116a is proximate to the exit third side 110cc relative to the first traveler 112a, and the second runner 116b is distal to the exit third side 110cc relative to the second traveler 112 b. In this embodiment, the first chute 116a and the second chute 116b are diagonally opposite to each other at two sides of the equipment abdicating port 110c, and the first sliding column 112a and the second sliding column 112b are diagonally opposite to each other at two sides of the equipment abdicating port 110 c. Therefore, the plurality of sliding fit portions are arranged in four directions of the main body support 11 and the adaptor support 12 in a relatively dispersed manner, so that when the adaptor support 12 moves relative to the main body support 11, the adaptor support 12 can be restrained by the sliding fit portions in each direction, and the risk of tilting to one side when the adaptor support 12 moves is reduced to a greater extent.

In one embodiment, the sliding engagement surfaces of the first sliding slot 116a and the first engagement portion 124a are flat surfaces, and the sliding engagement surfaces of the second sliding slot 116b and the second engagement portion 124b are flat surfaces. The sliding mating surface of the first sliding column 112a and the first sliding portion 122a is a cylindrical surface, and the sliding mating surface of the second sliding column 112b and the second sliding portion 122b is a cylindrical surface. After setting up like this, the fitting surface form is more diversified, compares the fitting surface that adopts single form, is favorable to balancing and adjusts the fit tolerance to can reduce the installation and cooperate the degree of difficulty, reduce the manufacturing accuracy of sliding fit position, practice thrift the cost. In other embodiments, the sliding engagement surfaces of the two sliding grooves 116 and the two engagement portions 124 may be cylindrical surfaces, and the sliding engagement surfaces of the two sliding columns 112 and the two sliding portions 122 may be planar surfaces, but are not limited thereto.

In one embodiment, as shown in FIG. 3, the first mating portion 124a includes an elevated portion 1240 connected to the equipment mounting portion 120 and an abutment portion 1242 connected to the elevated portion 1240, the elevated portion 1240 extending beyond an upper surface of the equipment mounting portion 120, the abutment portion 1242 extending bent relative to the elevated portion 1240 spaced apart from the upper surface of the equipment mounting portion 120. The elevated portion 1240 extends upward from the upper surface of the equipment mounting portion 120, and may increase the engagement length of the first engagement portion 124a and the first sliding groove 116a, which is beneficial to improving stability and smoothness during the sliding process. In one embodiment, the first matching portion 124a and the device mounting portion 120 are a single-piece structure, and the first matching portion 124a may be bent by a stamping process, but is not limited thereto. The second mating portion 124b may be configured in the same manner as the first mating portion 124a, and will not be described in detail herein.
