Technical Field

[0001] The invention relates to the technical field of dry wall screws, in particular to a dry wall screw with a side plate for preventing deflection by knocking. Background Art

[0002] With the development of society, drywall screws are a type of nails. The biggest feature in appearance is the trumpet head shape. They are divided into double-thread fine-thread drywall screws and single-thread coarse-thread drywall screws. The biggest difference between the two is that the former has double threads. The drywall screw series is one of the most important categories in the entire fastener product series. This product is mainly used for the installation of various gypsum boards, lightweight partition walls and ceiling series;

[0003] Compared with the anti-slip drywall screw of CN202251316U, there are four reinforcing ribs under the nail head to increase the friction between the anti-slip drywall screw and the connecting piece, effectively preventing the drywall screw from loosening and falling out due to vibration and other reasons, avoiding the occurrence of accidents and protecting the lives of people around. The traditional drywall screw with side plate knocking anti-deflection can basically meet people's use needs, but there are still certain problems, the specific problems are as follows:

[0004] 1. Most of the drywall screws with side panels on the market are installed by operators using their hands to hold the drywall screws. This method of holding by hand can easily cause finger injuries to operators.

[0005] 2. Currently, most of the drywall screws on the market that are equipped with side panels to prevent deviation cannot be clamped and fixed when the drywall screws are struck, causing the drywall screws to deviate during the striking process, thus affecting the use effect of the drywall screws. Summary of the invention

[0006] The purpose of the present invention is to provide a drywall screw with a side plate for anti-deflection during knocking, so as to solve the problem in the above background technology that when the drywall screws are knocked and installed, the operator uses the hand to hold the drywall screws for knocking and installation, which easily causes the operator's fingers to be injured.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a drywall screw with a side plate for knocking and anti-deflection, comprising a mounting plate, a handle, a wear-resistant plate, a drywall screw body, a fixing frame and an extrusion plate, wherein the bottom end of the mounting plate is installed with a mounting frame, and the side wall of one end of the mounting frame is installed with a handle, an mounting bin is opened inside the mounting plate, and the top and bottom ends of the mounting bin are installed with a fixing frame, a first conical toothed disc is installed in the interior of the fixing frame in a transverse manner through a ball bearing, a through hole is opened at the middle position inside the mounting plate, and the drywall screw body is arranged inside the through hole.

[0008] Preferably, a groove is provided inside the installation frame, and first slide rails are installed on the side walls at both ends of the groove, a first slider is provided inside the first slide rail, and a connecting plate is installed at one end of the first slider that is close to each other.

[0009] Preferably, a connecting rod is installed at the bottom end of the connecting plate, and a wear-resistant plate is installed at the bottom end of the connecting rod.

[0010] Preferably, a spring is installed at the top end of the connecting plate, and one end of the spring away from the connecting plate is connected to the top end inside the groove.

[0011] Preferably, a T-shaped rod penetrating the interior of the mounting bin is installed inside the mounting plate via a bearing, and the bottom end of the T-shaped rod is connected to the top end of the first conical gear disc.

[0012] Preferably, a second conical toothed disc is vertically mounted inside the fixing frame via a ball bearing, and a threaded hole is provided inside the second conical toothed disc, a threaded rod passing through the through hole is provided inside the threaded hole, and an extrusion plate is installed at one end of the threaded rod.

[0013] Preferably, a second slide rail is installed at the bottom end inside the installation bin, and a second slider is arranged inside the second slide rail, and the top end of the second slider is connected to the outer wall of the threaded rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A fixing frame, a first conical toothed disc, a T-shaped rod, a second conical toothed disc, a threaded hole and an extrusion plate are installed.
