[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1-Figure 3 As shown, the utility model discloses a limiter device for a magnetic drill, comprising a device body 1, wherein the device body 1 comprises a limiter body 11. The limiter body 11 is arranged on one side of the magnetic drill where a track is arranged.

[0027] The cross section of the stopper body 11 is in the shape of a concave letter. The magnetic drill is partially located in a recess on the stopper body 11. One side of the recess in the stopper body 11 fits with one side of the magnetic drill. An anti-slip pattern is provided on the side of the stopper body 11 that fits with the magnetic drill. The anti-slip pattern increases the friction between the stopper body 11 and the magnetic drill.

[0028] The top horizontal plane projection of the stopper body 11 partially overlaps with the bottom horizontal plane projection of the movable part in the magnetic drill. Since one side of the stopper body 11 fits with one side of the magnetic drill, the stopper body 11 itself will not tilt when impacted by the movable part in the magnetic drill.

[0029] The stopper body 11 is provided with a fixing portion, and the fixing portion fixes the stopper body 11 and the magnetic drill.

[0030] The fixing part includes two locking bolts 2. Both ends of the limiter body 11 are provided with threaded holes 21. Each locking bolt 2 is partially located in the corresponding threaded hole 21, and the locking bolt 2 is threadedly connected with the corresponding threaded hole 21. One end of each locking bolt 2 contacts one side of the magnetic drill.

[0031] A height adjustment bolt 12 is vertically arranged at the bottom of the stopper body 11, and the height adjustment bolt 12 is threadedly connected to the stopper body 11, and the bottom of the height adjustment bolt 12 contacts the top of the magnetic drill base. The top of the height adjustment bolt 12 never passes through the stopper body 11.

[0032] A support block 3 is provided on the outer circumference of the height adjustment bolt 12 away from the limiter body 11, and the bottom of the support block 3 is flush with the bottom of the height adjustment bolt 12. The cross-sectional area of ​​the support block 3 is 2 to 3 times the cross-sectional area of ​​the height adjustment bolt 12. In this embodiment, the cross-sectional area of ​​the support block 3 is 2.5 times the cross-sectional area of ​​the height adjustment bolt 12. The support block 3 increases the contact area between the height adjustment bolt 12 and the magnetic drill base, reduces the damage to the bottom of the magnetic drill when the device body 1 is subjected to external impact, and increases the service life of the magnetic drill base.

[0033] The cross section of the support block 3 is a hexagon. By setting the shape of the hexagon, it is more convenient for the operator to adjust the length of the height adjustment bolt 12 outside the limiter body 11 in time according to needs, thereby improving the adjustment work efficiency.

[0034] The implementation principle of the above embodiment is:

[0035] The operator first uses a tool to rotate the support block 3 according to the drilling requirements of the product, thereby achieving the purpose of rotating the height adjustment bolt 12 so that the length of the height adjustment bolt 12 outside the limiter body 11 meets the requirements.

[0036] Next, the operator places the device body 1 on the side where the guide rail is installed on the magnetic drill, and makes the magnetic drill part located in the depression in the stopper body 11, so that one side of the stopper depression fits with one side of the magnetic drill. At the same time, it is necessary to ensure that the bottom of the support block 3 fits with the top of the magnetic drill base.

[0037] Next, the operator keeps the current position of the device body 1 unchanged, and uses a tool to simultaneously rotate the two locking bolts 2 so that one end of the two locking bolts 2 fits against the corresponding sides of the magnetic drill.

[0038] After tightening the locking bolt 2, it is important to ensure that the position of the limiter body 11 is fixed and not easily shaken.

[0039] It is explained here that the stopper body 11 will not interfere with the normal drilling operation, and the stopper body 11 will not come into contact with the object being drilled.

[0040] When the above preparations are completed, the operator places the object to be drilled on the magnetic drill base and fixes it, and starts the magnetic drill to complete the drilling operation.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
