Embodiment

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, the following further details this application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0030] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0033] As Figures 1 to 2 shown, a magnetic drill motor limiting device provided by an embodiment of this application is described below. A magnetic drill motor limiting device includes:

[0034] Frame 1, on which a vertical slideway 11 is provided; on the frame 1, a through channel 13 for setting a gear is provided, and the through channel 13 is orthogonal to the vertical slideway 11;

[0035] Track structure 2, which is arranged in the vertical slideway 11;

[0036] The rack 3 is arranged in the vertical slideway 11, and the rack 3 is meshed with the gear;

[0037] The locking member 4 slides in a slide groove 111 of the vertical slideway 11, and the locking portion 41 of the locking member 4 is located behind the rack 3 and abuts against the tooth surface of the rack 3 to fix the rack 3;

[0038] The guide plate 5 is fixedly connected to the rack 3 and is slidably connected to the track structure 2. The front side of the guide plate 5 is connected to the motor of the magnetic base drilling machine.
