Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the handle drill jig tool with the clamping function of the utility model comprises a clamping clamp 1 and a drill jig head 2, wherein the drill jig head 2 comprises an upper part and a lower part which are respectively arranged on two clamping ends of the clamping clamp 1, a lock catch 11 capable of connecting the two handle ends is arranged at the tail parts of the two handle ends of the clamping clamp 1, when the clamping clamp 1 is in a closed state, the gap between the upper part and the lower part of the drill jig head 2 does not exceed the thickness of a workpiece 3 to be drilled, and the axes of through holes 21 on the upper part and the lower part of the drill jig head 2 are mutually aligned.

The application process of the utility model is as follows: first, the jig tool of the present utility model is applicable only to some hole forming areas near the edge of the workpiece 3 to be hole formed, because the holding forceps 1 cannot penetrate deep into the middle area of the workpiece. When the hole is formed, the hole forming position is determined firstly, then the through hole 21 on the drilling die head 2 is aligned to the hole forming position, the clamping pliers 1 are clamped, then the handle ends of the clamping pliers 1 are fixed by the lock catch 11, the clamping pliers 1 are ensured to be stably clamped and fixed on the workpiece 3 to be formed, and finally, the hole forming operation can be carried out by holding the drill with both hands.

In the folded state of the clamping pliers 1, the gap between the upper part and the lower part of the drill jig head 2 is preferably slightly smaller than the thickness of the workpiece 3 to be drilled, so that the drill jig head 2 and the workpiece 3 to be drilled can be ensured to be clamped and fixed when the handle is locked by the lock catch 11. The axes of the through holes 21 on the upper part and the lower part of the drill die head 2 are mutually aligned, which means that under the clamping state, the end faces of the upper part and the lower part of the drill die head 2 can be flush with the surface of the workpiece 3 to be clamped, so that the contact area is increased, the clamping stability is ensured, and meanwhile, the damage to the workpiece 3 to be drilled caused by the edge of the drill die head 2 is avoided.

In order to adapt to workpieces with different thicknesses and different apertures, the utility model sets the clamping ends of the drill die head 2 and the clamping pliers 1 in a detachable connection mode. Therefore, the drilling die head 2 can be modularized, different drilling die heads 2 can be designed according to different requirements for replacement, the applicability of the whole drilling die tool is improved, the cost is saved, and the economic benefit is improved.

For the detachable connection mode of the drill die head 2 and the clamping pliers 1, the utility model has the preferable scheme that the clamping end of the clamping pliers 1 is provided with the dovetail strip 12, one end of the drill die head 2 connected with the clamping pliers 1 is provided with the dovetail groove 22 matched with the dovetail strip 12, and the drill die head 2 is arranged on the clamping pliers 1 through the cooperation of the dovetail strip 12 and the dovetail groove 22. The dovetail grooves 22 are adopted for connection, so that the manufacturing is simple, the connection is stable and reliable, and the replacement is convenient.

In some cases where a plurality of holes are required to be formed in one place, a plurality of through holes 21 may be provided side by side on the jig head 2, and by one-time clamping, the drilling of the plurality of holes can be completed, and the relative positional relationship between the plurality of holes can be more easily ensured.

Further, the drilling jig further comprises a positioning pin 4, wherein the positioning pin 4 can be inserted between the through holes 21 of the upper part and the lower part of the drilling jig head 2, and the outer diameter of the positioning pin 4 is the same as the aperture of the through holes 21. For the condition that a plurality of holes need to be drilled, after one hole is drilled, the positioning pin 4 can be inserted from the through hole which is already formed in the drill jig head 2, so that a certain fixing effect is achieved on the drill jig head 2 and the workpiece 3 to be drilled, the drill jig head 2 can be prevented from being deviated in the subsequent hole making process, and the relative position relation among the plurality of holes is ensured.
