Description

  The present invention relates to a wrench, and more particularly to a wrench used for mounting and positioning screws and nuts.

  1 to 3 are explanatory views showing a conventional wrench.

  According to the drawing, the wrench comprises a drive head 10 and a handle portion 20.

  The drive head 10 includes a pivotal portion 11 provided on the outer peripheral edge portion, and an uneven surface 12 provided in an annular arrangement on the pivotal portion 11.

  The handle portion 20 is provided with a concave portion 21 provided at the front end edge portion to pivot on the pivot portion 11.

  The pivot portion 11 is provided with a through hole 111 penetrating laterally, and the concave portion 21 is provided with a hole 22 at a position corresponding to the through hole 111 in a convex portion protruding on both sides.

  Therefore, when the pivot 30 is drilled through the hole 22 and the through hole 111, the handle portion 20 and the drive head 10 are rotatably connected.

  At the bottom of the concave portion 21, a guide hole 24 provided in a vertical longitudinal direction and a lateral lateral hole 23 penetrating the guide hole 24 are provided.

  In the guide hole 24, a hook-like locking block 13 is slid and provided. The lateral hole 23 is formed laterally from the side surface of the handle portion 20 to a depth exceeding the guide hole 24.

  The pressing rod 32 has a guide surface 321 having a slope on the outer peripheral surface. A circular head end 131 at the bottom end of the locking block 13 is provided corresponding to the guide surface 321.

  Therefore, when the locking block 13 is driven, the meshing end 132 formed at the other end edge of the locking block 13 is meshed with the uneven surface 12 of the drive head 10.

  However, in the conventional wrench, when the circular head end 131 is provided at one end of the locking block 13 and the meshing end 132 is provided at the other end, the correct direction must be selected when fitting into the guide hole 24. However, it is easy to make a mistake in selection.

  Further, in the conventional wrench, when the circular head end 131 of the locking block 13 and the guide surface 321 are combined, there is no guide structure for combining them at the correct position, so the engagement end 132 is engaged with the uneven surface 12. It is difficult.

  Furthermore, when the conventional wrench is moved by driving the locking block 13 by pressing with the pressing rod 32, the engagement end 132 of the locking block 13 and the uneven surface 12 are not parallel, and the angle cannot be positioned. .

  This invention makes it a subject to provide the wrench which can position a combination angle easily.

Explained.

  4 and 5 are explanatory views showing the wrench of the present invention.

  The wrench according to the present invention includes a drive head 40 and a handle portion 50.

  The drive head 40 includes a pivot 41 having an uneven surface 42 arranged annularly on one side of the outer peripheral surface.

  The handle portion 50 forms a concave groove 51 for pivoting on the front end edge portion, and serves to pivot on the pivot portion 41.

  The pivotal portion 41 is provided with a through hole 411 formed laterally from the side surface of the drive head 40.

  The concave groove 51 is provided with perforations 52 corresponding to the through-holes 411 on the projecting convex portions on both sides.

  Therefore, the pivot 60 is drilled in the perforation 52 and the through hole 411 to pivotally connect the handle portion 50 and the drive head 40.

  A guide hole 54 is provided at the bottom of the concave groove 51 in the vertical longitudinal direction. The guide hole 54 is provided for sliding with a locking block 70.

  A hole 53 is formed laterally from the side surface of the handle portion 50, and the hole 53 penetrates the guide hole 54 and is formed deeper than that.

  Therefore, a spring 81 and a pressing rod 82 are provided in the hole 53.

  The pressing rod 82 has a guide surface 821 having an inclined outer peripheral surface.

  The locking block 70 is a circular casing, and is formed such that one end and the other end of the locking block 70 have a slope and are pointed, and a first slope 71 and a second slope 72. And formed.

  The first and second slopes 71 and 72 at one end and the other end are provided vertically and horizontally by turning 90 degrees with respect to each other.

  A guide surface 821 having an inclined surface is provided at the position of the second inclined surface 72 at the bottom end of the locking block 70 and drives the first inclined surface 71 formed at the upper end of the locking block 70 to form the uneven surface 42 of the driving head 40. Engage.

  As described above, the locking block 70 can be easily provided, and the locking block 70 and the pressing rod 82 can be correctly guided to engage with each other more accurately.

  Moreover, since the structure is simple, the production process can be simplified, and the industrial efficiency and profit can be increased.

  As disclosed in FIGS. 6 and 7, the first inclined surface 71 is pressed by the guide surface 821 of the pressing rod 82 and accurately meshed with the tooth groove of the uneven surface 42.

  The pressing rod 82 maintains a fixed pressure by the elastic force of the spring 81 and is transmitted to the locking block 70 through the guide surface 821.

  The guide surface 821 simultaneously guides the second slope 72 of the locking block 70 to the correct position.

  As disclosed in FIGS. 8 and 9, a guide surface 822 having a slope is provided on the side of the pressing rod 82 facing the guide surface 821.
