[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Combine the following Figures 1 to 4 The utility model is described in detail.

[0024] A top plate drilling auxiliary bracket comprises a support rod 1, a chassis 101 is arranged at the bottom of the support rod 1, a roller 102 is arranged at the bottom of the chassis 101, a lifting rod 2 is connected to the support rod 1 near the top side, a deflection block 3 is connected between the support rod 1 and the lifting rod 2, a hinge shaft 301 is connected near both ends of the deflection block 3, the deflection block 3 is inclinedly connected to the support rod 1 and the lifting rod 2 through the hinge shaft 301, a reinforcement block 4 is connected below the deflection block 3, a slide groove 103 is arranged on one side of the support rod 1 near the top, a limiting component is arranged on one side of the lifting rod 2, the limiting component slides along the slide groove 103, two hinge shafts 301 on the deflection block 3 are respectively connected to the lifting rod 2 and the support rod 1, a rod body is extended at one end of the deflection block 3, and the rod body extended at one end of the deflection block 3 is a handle, and the reinforcement block 4 is a plate connected to the lifting rod 2 and the support rod 1 through the hinge shaft 301 in accordance with the deflection block 3.

[0025] First, the support rod 1 is supported vertically on the ground through the chassis 101, and then moved through the roller 102 at the bottom of the chassis 101. At the same time, the side of the support rod 1 close to the top is connected to the lifting rod 2 through the deflection block 3 and the reinforcement block 4. At the same time, because the deflection block 3 and the reinforcement block 4 are connected to the lifting rod 2 and the support rod through a hinge shaft, the deflection block 3 can be pressed by applying pressure to the rod handle extending from one end of the deflection block 3 to force the deflection block 3 to rotate along the hinge shaft 301 connected to the support rod 1, so that the entire deflection block 3 can be rotated. The block 3 is deflected, thereby driving the lifting rod 2 connected to the other end to rise in the direction of the deflection, thereby driving the connecting block 201 connected at the top to rise close to the top plate, and an electric drill is connected to the connecting block 201, which drives the electric drill to approach the roof plate through the connecting block 201 to drill holes in the roof top plate, and then the lifting rod 2 is raised and lowered by the deflection of the deflection block 3, so as to complete the drilling of the roof top plate, without the need to build a herringbone ladder to contact the roof top plate.

[0026] The reinforcing block 4 can enhance the stability of the lifting rod 2 during the lifting process.

[0027] Furthermore, the limiting component includes a slider 202 and an elastic stopper 2021. The slider 202 is arranged on the side of the lifting rod 2 close to the bottom end, and the elastic stopper 2021 is arranged on both sides of the slider 202. Bumps are arranged on both sides of the slider 202, and long strip-shaped grooves are arranged on both sides of the middle of the slide groove 103, and the bumps on both sides of the slider 202 cooperate with the grooves on both sides of the middle of the slide groove 103. The thickness of the bumps on both sides of the slider 202 is smaller than the grooves on both sides of the middle of the slide groove 103. The elastic stopper 2021 is a block connected to one side of the bumps on both sides of the slider 202 by a spring, and the elastic stopper 2021 connected by a spring fits on one side of the grooves on both sides of the middle of the slide groove 103.

[0028] When the lifting rod 2 is lifted and lowered by the deflection of the deflection block 3, it will move along the slide groove 103 through the slider 202. At the same time, during the movement, the protrusions on both sides of the slider 202 will fit in the grooves on both sides of the slide groove 103, so that the lifting rod 2 will maintain the connection with the support rod 1. At the same time, elastic abutments 2021 are connected to the protrusions on both sides of the slider 202 through springs, and the elastic abutments 2021 are abutted against one side of the grooves on both sides of the slide groove 103. Therefore, when the lifting rod 2 is lifted and lowered due to the deflection of the deflection block 3, the protrusions on both sides of the slider 202 will be close to the elastic abutments 2021, compressing the spring. The return thrust of the spring generates force to stabilize the lifting rod 2, and at the same time, the slider 202 or the elastic block 2021 will fit tightly against one side of the groove in the slide slot 103 during the lifting process, so that when the lifting rod 2 is deflected and lifted by the deflection block 3, the connection between the slider 202 and the slide slot 103 will not be separated due to the left and right displacement of the lifting rod 2, making the lifting rod more stable and not prone to shaking during lifting. At the same time, telescopic rods are connected between the convex blocks on both sides of the slider 202 and the elastic block 2021, so that the elastic block 2021 will deviate from the convex blocks on both sides of the slider 202 during the friction displacement.

[0029] The following is a specific implementation process of the utility model. First, the support rod 1 is supported upright on the ground through the chassis 101, and then moved through the roller 102 at the bottom of the chassis 101. At the same time, the side of the support rod 1 close to the top is connected to the lifting rod 2 through the deflection block 3 and the reinforcement block 4. At the same time, because the deflection block 3 and the reinforcement block 4 are connected to the lifting rod 2 and the support rod through a hinge shaft, the deflection block 3 can be forced to rotate along the hinge shaft 301 connected to the support rod 1 by applying pressure to the rod handle extending from one end of the deflection block 3. , so that the entire deflection block 3 is deflected, thereby driving the lifting rod 2 connected at the other end to rise in the deflection direction, thereby driving the connecting block 201 connected at the top to rise close to the top plate, and an electric drill is connected to the connecting block 201, and the electric drill is driven by the connecting block 201 to approach the roof plate to drill holes in the roof top plate, and then the lifting rod 2 is raised and lowered by the deflection of the deflection block 3, so as to complete the drilling of the roof top plate, without the need to build a herringbone ladder to contact the roof top plate.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
