[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] An auxiliary tooling for screw installation, as Figures 1-3 shown, includes a body 1, a guide rod 2, an upper connecting plate 3, a lower connecting plate 4, a spring 5, a first connecting member 6, a second connecting member 7, a nut seat 8 and a bolt seat 9. Two through guiding holes are arranged at intervals on the body 1. The guide rods 2 are respectively arranged in the guiding holes. The upper connecting plate 3 is connected to the upper ends of the guide rods 2, and the lower connecting plate 4 is connected to the lower ends of the guide rods 2 to improve the stability of the movement of the lower connecting plate 4 and prevent the lower connecting plate 4 from rotating. The spring 5 is sleeved on the guide rod 2 and is between the upper connecting plate 3 and the upper surface of the body 1. The spring 5 is used to make the lower connecting plate 4 closely adhere to the lower surface of the body 1; the nut seat 8 is arranged on the lower connecting plate 4 through the second connecting member 7, and the bolt seat 9 is arranged on the body 1 through the first connecting member 6, and the center lines of the bolt seat 9 and the nut seat 8 are on the same straight line. That is, when in use, the positions of the bolts and the screw holes of the nuts correspond.

[0018] In one embodiment, as Figures 1-3 shown, the bolt seat 9 includes a first seat body 91, a rotating body 92 and a bolt mounting seat 93. The first seat body 91 is fixedly arranged on the first connecting member 6. The rotating body 92 is rotatably arranged on the first seat body 91. The upper end of the rotating body 92 is provided with an interface for cooperating with a rotating mechanism (such as an electric screwdriver). The lower end is recessed with a first notch 94 for cooperating with the bolt mounting seat 93, and a magnet is arranged at the bottom of the first notch 94. The bolt mounting seat 93 is fixed in the first notch 94 through the magnet. The first notch 94 is polygonal, such as triangular, quadrilateral and so on; of course, it can also be a special-shaped structure. Through the replaceable bolt mounting seat 93, it can be replaced according to screws of different sizes.

[0019] In one embodiment, as Figures 1-3 shown, the nut seat 8 includes a second seat body 81 and a nut mounting seat 82. The second seat body 81 is recessed with a second notch 83 for cooperating with the nut mounting 82 seat. The second notch 83 is polygonal. A magnet is arranged at the bottom of the second notch 83. The nut mounting seat 82 is fixed in the second notch 83 through the magnet. Through holes allowing the bolts to pass through are arranged at the bottoms of the second notch 83 and the nut mounting seat 82.

[0020] In one embodiment, as Figures 1-3As shown, the first connecting member 6 includes a first fixed rod 61, a first movable rod 62, and a locking screw 63. The first fixed rod 61 is horizontally provided with a guide groove for cooperating with the first movable rod 62, and a waist-shaped hole 64 communicating with the guide groove is provided on one side wall thereof. A threaded hole for cooperating with the locking screw 63 is provided on the first movable rod 62. The first movable rod 62 is slidably arranged in the guide groove, and the first fixed rod 61 and the first movable rod 62 are fixed by the locking screw 63, so as to realize the quick adjustment of the extending distance of the bolt seat 9 to one side.

[0021] In one embodiment, as Figures 1-3 shown, the second connecting member 7 includes a second fixed rod 71, a second movable rod 72, and a locking nut 73. The second fixed rod 71 is horizontally provided with an adjustment groove, and a connecting portion 74 and a pressing portion 75 are extendedly provided at the end of the adjustment groove. External threads for cooperating with the locking nut 73 are provided on the outer wall of the connecting portion 74. The pressing portion 75 is composed of at least three petals, and the outer wall is an inclined surface. Correspondingly, a matching inclined surface is provided inside the locking nut 73, and the pressing portion 75 is pressed towards its center by the locking nut 73. Specifically, rotate the locking nut 73 so that the inclined surface inside the locking nut 73 presses the pressing portion 75 towards the center to increase the friction between the pressing portion 75 and the second movable rod 72, thereby realizing the connection between the second fixed rod 71 and the second movable rod 72.

[0022] In one embodiment, as Figures 1-3 shown, a grip is provided on the body 1.

[0023] When the present invention is in use, as Figures 1-3 shown, first adjust the extending distances of the nut seat 8 and the bolt seat 9. Specifically, loosen the locking screw 63, directly pull out the first movable rod 62 to the designated position, and then tighten the locking screw 63. Loosen the locking nut 73 so that the inclined surface inside the locking nut 73 is away from the pressing portion 75, reducing the pressure between the pressing portion 75 and the second movable rod 72, so that the second movable rod 72 can be pulled out to correspond to the position of the bolt seat 9, and then tighten the locking nut 73 so that the pressing portion 75 presses the second movable rod 72 tightly. Then replace the bolt mounting seat 93 and the nut mounting seat 82 that cooperate with the bolts and nuts to be replaced. And install the nut and the bolt in the nut mounting seat 82 and the bolt mounting seat 93 respectively. The staff separates the nut from the bolt, inserts the nut end into the space between the mounting plate and the electric box, inserts the bolt into the mounting hole of the mounting plate, and then loosens it. At this time, using the elastic force of the spring 5, the nut and the bolt are brought into contact. The staff can directly hold the body 1 with one hand. With the other hand, drive the rotating body 92 to rotate by an electric screwdriver to drive the bolt to rotate, so as to realize the connection and fixation between the bolt and the nut.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention; any modifications or equivalent substitutions made to the present invention without departing from the spirit and scope of the present invention shall fall within the protection scope of the claims of the present invention.
