DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] A drilling positioning auxiliary device, such as Figure 1 and Figure 2As shown, it includes a handle 1, a threaded arm 2, a straight column 3, a lower arm 4, a folding arm 5, a pulley 6, a tail hook 7 and a clamping mechanism 8. The left and right sides of the handle 1 are threadedly connected to the threaded arms 2, the bottom of the threaded arms 2 are connected to the straight columns 3, the bottom of the straight columns 3 are connected to the lower arms 4, the bottom of the lower arms 4 are connected to the folding arms 5, the left and right parts of the folding arms 5 are rotatably connected to the pulley 6, the folding arms 5 are connected to the tail hooks 7, and the clamping mechanism 8 is provided on the tail hooks 7.

[0019] like Figure 1 and Figure 3 As shown, the clamping mechanism 8 includes an adjusting ring 81, a spring 82, a telescopic rod 83 and a clamping plate 84. The tail hook 7 and the upper part of the lower arm 4 are connected to the adjusting ring 81, the bottom of the adjusting ring 81 is connected to the telescopic rod 83, adjacent telescopic rods 83 are slidably connected to the clamping plates 84, and the adjusting ring 81 and the adjacent clamping plates 84 are connected to the spring 82.

[0020] like Figure 1 and Figure 4 As shown, it also includes a binding mechanism 9, which includes a screw ring 91, an outer ring 92 and a binding strap 93. The screw ring 91 is threadedly connected to the threaded arm 2, the outer ring 92 is rotatably connected to the screw ring 91, and the outer rings 92 are connected with binding straps 93.

[0021] When the utility model is in use, the screw sleeve ring 91 is first rotated to make the outer ring 92 approach or move away from each other. The movement of the outer ring 92 approaching or moving away from each other can control the tension of the strap 93. The strap 93 is used to fix the user's hand and the handle 1 to increase the stability when grasping. The user grasps the handle 1 and uses the folding arm 5 to lift and support the drill rod. The drill rod passes between the clamping plate 84 and the folding arm 5. The clamping plate 84 limits the drill rod so that the drill rod is restricted between the clamping plate 84 and the folding arm 5, so that the drill rod will not slip off the folding arm 5 when drilling. When the drill rod is drilling, the folding arm 5 lifts and supports the drill rod to support and align the drill rod, which is convenient for determining the position of the drill hole. The pulley 6 can reduce the friction between the drill rod and the folding arm 5 and increase the service life of the folding arm 5.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
