[0013] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0014] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See also Figure 1 As shown, the present embodiment involves a protective door steel plate drilling tool, comprising a horizontally arranged hole positioning plate 1, the bottom of the hole positioning plate 1 is provided with a horizontal support plate 2 arranged on the top and a longitudinal support plate 3 arranged on the left, a fixed positioning hole 4 is opened on the hole positioning plate 1, and a symmetrically arranged adjusting disk 5 is respectively provided on the front and rear sides of the fixed positioning hole 4, the adjusting disk 5 is rotatably connected to the hole positioning plate 1, and an eccentric movable positioning hole 6 matching the fixed positioning hole 4 is provided on the adjusting disk 5.

[0017] Furthermore, three adjacent shifting grooves 7 with an interval of 90° are arranged on the circumference of the adjusting disc 5 , and all the shifting grooves 7 and the movable positioning holes 6 are arranged on the same structural circle.

[0018] Furthermore, the interval angle between the movable positioning hole 6 and the adjacent pull groove 7 is 90°.

[0019] In this embodiment, first, the drilling tool is Figure 1 In the state shown, the three holes are located on the same straight line, and the hole spacing is the "small spacing" specification; when the hole spacing specification needs to be changed from "small spacing" to "large specification", the adjustment disk 5 is rotated 180° so that the three holes are still located on the same straight line. At this time, the hole spacing is the "large spacing" specification. Take the drill bit, pass through the hole, and then you can drill a hole in the steel plate that is close to it.

[0020] The setting of the dial groove 7 is used to turn the adjusting disc 5 .

[0021] Example 2

[0022] See also Figure 1 As shown, the present embodiment involves a protective door steel plate drilling tool, which is further configured on the basis of Embodiment 1, that each of the adjusting discs 5 is matched with an elastic pressing plate 8, one end of the elastic pressing plate 8 is connected to the hole positioning plate 1, and the other end is provided with a positioning protrusion 81 embedded in the pull groove 7.

[0023] Furthermore, the elastic pressing sheet 8 is made of metal material.

[0024] In this embodiment, the elastic pressing piece 8 cooperates with the positioning protrusion 81 so that the adjusting disc 5 can be limited by the elastic pressing piece 8 every time it rotates 90°, thereby limiting the rotation angle and ensuring the accuracy of the adjustment angle.

[0027] In this embodiment, the wear-resistant bushing is provided to protect the wall of the hole (including the fixed positioning hole 4 and the movable positioning hole 6).

[0028] The protective door steel plate drilling tool involved in the utility model achieves a quick positioning effect of the hole positioning plate by using a horizontal support plate to vertically position the hole positioning plate and using a longitudinal support plate to horizontally position the hole positioning plate. A fixed positioning hole and two movable positioning holes thereon are combined to form the required drilling holes. Since the position of the movable positioning hole can be adjusted after the adjusting disk is rotated 180°, the function of adjusting the spacing between adjacent drilling holes can be realized. The overall function is complete and the practicability is strong.
