Detailed Description

The embodiment of the utility model relates to a hand-held type building board line hole puncher is further explained with reference to fig. 1.

The utility model provides a hand-held type building board central line hole puncher, includes drilling motor 1, be equipped with drill bit 11 in drilling motor 1's the pivot, drilling motor 1's back is equipped with double-screw bolt 2, the spiro union has holding ring 4 on the double-screw bolt 2, be equipped with central symmetry and isometric locating lever 5 on the circumference lateral wall of holding ring 4, the tip of locating lever 5 is equipped with electric putter 6, electric putter 6's one end is equipped with clamping mechanism.

When the building board 12 is punched, firstly, the positioning ring 4 is rotated according to the width of the building board 12, so that the clamping mechanism at one end of the electric push rod 6 abuts against two sides of the building board 12, then the two sides of the building board 12 are clamped through the clamping mechanism, because the positioning rods 5 are equal in length and are centrosymmetric, and the drill bit 11 is positioned at the midpoint position of the connecting line of the two positioning rods 5, namely the drill bit 11 is positioned at the midpoint position of the connecting line of the two clamping mechanisms, the centerline position of the drill bit 11 on the building board 12 can be obtained according to the principle that the midpoint of the connecting line of opposite sides of a rectangle is positioned at the centerline of the rectangle, after the fixation is finished, the electric push rod 6 and the drilling motor 1 are started, the electric push rod 6 drives the building board 12 to ascend and gradually contact with the drill bit 11, then the drilling motor 1 drives the, the efficiency and the precision of the line punching of the building board 12 are improved.

The preferred clamping mechanism of this embodiment includes the first clamp plate 7 fixed with electric putter 6 one end, the axle center department of first clamp plectane is equipped with swivel nut 10, threaded connection has locking bolt 9 in the swivel nut 10, locking bolt 9's middle part is fixed with second clamp plate 8, and when fixed building board 12, rotational positioning ring 4 makes building board 12's both sides contradict on the outer wall of swivel nut 10, then rotates locking bolt 9 for second clamp plate 8 presss from both sides tightly fixedly with building board 12.

In the preferred embodiment, a handle 3 is arranged at one end of the stud 2, so that an operator can hold the device conveniently.

The preferred first clamping plate 7 and second clamping plate 8 of this embodiment are both cylindrical in shape, and the cylindrical design is such that the clamping surfaces are the same regardless of how the two second clamping plates 8 rotate, thereby ensuring effective clamping of the building board 12.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
