[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figures 1-4 Presented is a GNSS receiver centering rod anti-shake device. The present invention includes a main rod 1 and a receiver 11 fixed above the main rod 1. A sliding sleeve 2 is slidably connected to the outer side of the main rod 1. A first locking pin 3 extending into and contacting the main rod 1 is threadedly connected to the outer side of the sliding sleeve 2. An auxiliary support crossbar 4 is slidably connected inside the sliding sleeve 2. A fixing component 5 is fixedly installed at the end of the auxiliary support crossbar 4. An auxiliary stabilizing ring 6 is slidably connected to the outer side of the main rod 1. A second locking pin 7 extending into the outer side of the auxiliary stabilizing ring 6 is threadedly connected to the outer side of the auxiliary support crossbar 4. A support sleeve 8 is slidably connected to the outer side of the support sleeve 8. An auxiliary support rod 9, the other end of which is rotatably connected to the outer side of the auxiliary stabilizing ring 6, is rotatably connected to the outer side of the support sleeve 8.

[0028] Furthermore, the bottom of the main rod 1 is pointed, and the main rod 1 is a telescopic rod that can push the receiver 11 up and down.

[0029] Furthermore, the fixing component 5 includes a puncture sleeve 51 fixed to the end of the auxiliary support crossbar. An elastic sheet 52 is provided inside the puncture sleeve 51. At both ends of the elastic sheet 52, barbs 53 extending to the outside of the puncture sleeve 51 are fixedly installed. A compression block 54 that contacts the barb block 53 and extends to the top of the puncture sleeve 51 is slidably connected inside the puncture sleeve 51.

[0030] Particularly, the inverted hook block 53 is in sliding connection with the puncture sleeve 51, and the puncture sleeve 51 can limit the moving direction of the inverted hook block 53, so that it can only move horizontally;

[0031] Further, the extrusion block 54 is provided with an inclined angle at one end inside the puncture sleeve 51, and the chamfer surface of the extrusion block 54 is polished and in contact with the inverted hook block 53.

[0032] In use, the fixing assembly 5 can be inserted into the ground through the puncture sleeve 51 to complete the preliminary fixation, and then the extrusion block 54 is pushed to push the inverted hook blocks 53 on both sides to start moving outward, so as to pull part of the soil to complete the fixation of the whole fixing assembly 5. When fixation is not needed, the extrusion block 54 can be pulled upward, so that the inverted hook blocks 53 start to reset under the action of the elastic sheet 52, so that the fixing assembly 5 is more easily separated from the soil.

[0033] Further, the outer part of the main rod 1 is provided with a longitudinal auxiliary support member 10, which includes a fixed ring 101 fixed to the outer part of the main rod 1, and a stable rod 102 rotatably connected to the outside of the fixed ring 101.

[0034] Further, the longitudinal auxiliary support member 10 further includes a storage rack 103 fixed to the outer part of the main rod 1, and the end part of the stable rod 102 is provided in a sharp manner.

[0035] When auxiliary support is needed, the stable rod 102 can be rotated and inserted into the soil to complete the auxiliary stabilization, and when it is not needed, the stable rod 102 can be stored through the storage rack 103, which is convenient to use.

[0036] Working principle:

[0037] In use, the position of the receiver 11 needs to be determined first, and then the main rod 1 is inserted into the ground and adjusted in position, and then the auxiliary stabilization ring 6 is slid to the lower part of the receiver 11, and the auxiliary stabilization ring 6 is fixed by the locking pin 7, so that it can hold the receiver 11. Due to the upward movement of the position of the auxiliary stabilization ring 6, the angle of the auxiliary support rod 9 and the position of the support sleeve 8 start to change until they cannot move, and then the auxiliary support cross rod 4 is slid, so that one side of the fixing assembly 5 abuts against the support sleeve 8 to form a support, and then the whole device is further punctured into the ground, and the fixing assembly 5 and the longitudinal auxiliary support member 10 are fixed to complete the whole fixation. After fixation is completed, the receiver 11 is supported by the main rod 1 and the auxiliary stabilization ring 6 at the same time, and the support effect is significantly uniform.
