In this embodiment, the number of the fixing blocks 221 may be 1 or two, and the fixing blocks are preferably connected to the mounting posts 21 by bolts.
The specific working process of the holding frame 22 is that once the receiver or the antenna is placed towards the surface of the fixing block 221, the receiver or the antenna is first held by the holding elastic block 222, so that the receiver or the antenna does not have a position shift phenomenon during the fixing process, and then when the receiver or the antenna (for convenience of description, the receiving part is referred to as a receiving part, hereinafter, the receiving part is referred to as a receiving device or an antenna) slides to contact the surface of the fixing block 221, the receiving part compresses the holding ring set 224, so that the position of the receiving part is further fixed and is not easily loosened, and after the initial fixing is completed, the holding pressing mechanism 5 is pulled to drive the fixing clamp 225 to move, so as to increase the holding force applied to the receiver or the antenna to be installed.

When the clamping elastic block 222 works specifically, the receiving component contacts the limiting post 2223 first (the specific structure of the limiting post 2223 may be the structure shown in fig. 4 and 5), and the movable bar 2221 is provided with an inclined surface, when the receiving component is closer to the fixed block 221, the limiting post 2223 is driven by the component to gradually approach the fixed block 221, at this time, the distance between the two fixed blocks 221 is reduced, the clamping force is increased, the attaching block 2224 may select rubber, which can ensure the stability of attachment, and the inclined piece 2225 can prevent one side of the receiver or the antenna to be installed from tilting.
As shown in fig. 1, the movement assisting mechanism 4 includes a threaded column 41 connected to the side wall of the mounting column 21, both ends of the threaded column 41 are connected with a pulling sleeve 42, the two pulling sleeves 42 can be close to or far away from the threaded column 41 simultaneously, the side wall of the mounting column 21 is provided with a cylinder limiting groove 43, the cylinder limiting groove 43 can limit the pulling sleeve 42, the outer surface of the pulling sleeve 42 is provided with at least one limiting brake groove 44, and the limiting brake groove 44 is connected with the clamping and pressing mechanism 5.

The specific structure of the clamping and pressing mechanism 5 is not exclusive, but the clamping and pressing mechanism 5 in the present embodiment is preferably configured to be able to perform an operation of fixing the receiving member.
The screw column 41 is directly driven to rotate (specifically, the screw column 41 is driven to rotate by passing through a rotating screw on the mounting housing 1 through the engagement between the gears), then the rotating screw column 41 drives the two pulling sleeves 42 to simultaneously approach or separate from each other along the screw column 41 (thus, the two pulling sleeves 42 simultaneously approach along the screw column 41 as illustrated by the fixing example), then the two pulling sleeves 42 which are close to each other pull the fixing clip 225, specifically, the extension strip 2252 through the limiting stopping groove 44, and when the extension strip 2252 is pulled, the extension strip can slide along the through hole 521 on the clamping sleeve 52 to clamp the receiving component, so that the receiving component can be bound on the fixing block 221.
Then, the extension strip 2252 sliding along the through hole 521 pushes the elastic pressing column 53 to move toward the receiving member, thereby increasing the clamping force to the elastic member, and securing the fixing stability greatly by the clamping in both ways.
The deformation block 54 can deform when pressed against the receiving component to fully conform to the surface of the component, and the sizing ring 55 can prevent the deformation block 54 from disengaging from the elastic pressing post 53.
