Description

Tool for quick adjustment of the opening

The present invention primarily discloses a tool, and more particularly a tool that can quickly adjust an opening.

Please refer to the "Pliers Structure" patent of the Chinese Patent No. M513095, which discloses a pipe wrench structure, which comprises: a first body provided with a first working end, a first receiving groove, a second receiving groove and a plurality a first toothed portion, the second receiving groove has two first abutting faces; a second body is provided with a second working end, a third receiving groove, a first pivot hole and a second pivot hole; a first pivot portion disposed in the first pocket and the first pivot hole, and a second pivot portion embedded in the second pivot hole, the two sides of the first pivot portion are disposed to be engaged with the first tooth portion a plurality of second tooth portions, the first side of the first pivot portion is provided with two first limiting surfaces; a third control member is coupled to the first pivot portion by an outer side of the second body; an elastic member is disposed at the second An elastic force is generated between the body and the third control member to move the third control member away from the second body; a positioning piece is sleeved on the first pivot portion, and the two second abutting surfaces respectively are opposite to the second receiving groove The first abutting surface is engaged, so that the positioning piece can slide along the second receiving groove, and has two second limiting faces, and the two second limiting faces are respectively associated with the first control The two first limiting faces of the piece are engaged, so that the first control member can only be axially displaced and cannot be axially rotated.

However, the pipe wrench adopting the above structure achieves the positioning effect between the first body and the second body through the first tooth portion and the second tooth portion, and must first exit the first control member to make the second The tooth portion is disengaged from the first tooth portion, and the first body and the second body are relatively movable. After being adjusted to an appropriate position, the first control member is reinserted, and the second tooth portion must be inserted before the first control member is inserted. Aligning the first tooth portion is not only cumbersome to operate, but the positioning structure of the first body and the second tooth portion is restricted by the positioning structure that the first tooth portion and the second tooth portion are engaged with each other, and the teeth of the two tooth portions must be matched. Spacing, not arbitrary positioning.

In view of the above-described deficiencies in the conventional structure, the inventors have devised a tool for quickly adjusting the opening which overcomes all of the disadvantages of the above-described conventional structure.

The utility model relates to a tool for quickly adjusting an opening, and the main object thereof is to provide a tool comprising a first clamping member, a second clamping member and a locking device, the first clamping member being provided with a clip at one end thereof Holding the end and providing a holding end at the other end, the first clamping member is provided with a left side, a right side different from the left side, a front side and a rear side different from the front side, The first clamping member is provided with a pivot slot extending from the left side through the first clamping member and extending to the right side, the pivot slot being adjacent to the end of the clamping end to a length adjacent to the end of the holding end More than a width of the pivot slot from a side adjacent to the front side to a side adjacent to the rear side, a pivot hole is disposed between the two ends of the second clamping member, the locking device includes a sliding member and an adjustment And a retaining device, one end of the sliding member is provided with a first head and the other end is provided with an external thread portion and a first retaining portion, the first head has a radial width Greater than the width of the pivot slot, between the two ends of the sliding member The sliding portion is disposed in the pivot hole and is slidably disposed on the pivot slot relative to the first clamping member.
