IX. INSTRUCTION DESCRIPTION: 1. Field of the Invention The present invention relates to a wrench, and more particularly to a ratcheting movable wrench. [Prior Art] As shown in FIG. 1 , the movable wrench 10 has a handle n and a fixing hole 12 , and a guiding slot 13 and a receiving hole 14 respectively connected to the handle u and communicating with each other. An adjusting cymbal 15 rotatably mounted in the accommodating hole 14 is inserted into the guiding groove 13 and can be driven by the adjusting amp 15 to produce a linearly moving follower rod 16 and a molding The follower rod 16 is flush with the movable jaw 17 of the fixed jaw 12. In use, when the adjusting mast 15 is rotated, the driven rod 线性 can be linearly moved to change the distance between the movable jaw 17 and the fixed piece 12, so that different sizes of screw locks can be sandwiched and rotated ( Although not shown in the figure, although the movable wrench 10 has the above-mentioned use characteristics, the following defects still exist: Since the operation is often limited by the small operation space, the movable wrench H) drives the screw to rotate after a predetermined stroke. , the screw must be turned to drive the screw to continue to rotate, but because the movable jaw 17 and the fixed display 12 are positioned in the use of the material, the adjustment must be reversed before the adjustable wrench iq turns 埚The rod 15 causes the movable 12 Η 12 to simultaneously disengage the screw lock member: the solid rotation, and after the autumn 霪咿勖 the screw lock member needs to rotate the adjustment worm 15 to make the movable 颚 fixed piece 12 cooperate again When the screw is clamped, it can continue to drive the rotation of the two t. In practice, there is a less convenient use. The present invention is directed to providing a threadable lock member: a gripper movable movable panel of the present invention is provided by using a relatively convenient ratcheting movable gripper. The hand comprises a body, a spoon, a slave unit, an i unit, a blocking member, and an elastic member. The i body comprises a handle, a head formed from the end of the handle, a fixed jaw formed from the head in the first direction, and a second direction perpendicular to the first angle The first and second guiding grooves communicating with each other in a direction perpendicular to the first direction and the second direction are disposed in the head and communicate with the receiving hole of the first guiding groove, the head a third guiding groove disposed on the outer circumferential surface facing the second guiding groove; and the third guiding groove is expanded to form and communicate with the fourth guiding groove of the first guiding groove. The adjustment unit includes a rotatably mounted moving worm. (4) the moving unit includes a follower rod mounted in the first guide groove and movable in the second direction by the adjustment (4) rod drive, - formed from the follower rod along the (four) direction and located at the second a connecting block in the guiding groove and a movable piece formed in the first direction from the connecting block, the movable piece having a clamping surface facing the fixed jaw. The engine unit includes a movable seat and a block, the movable seat has a slider movably sliding into the third guiding slot, and is formed from the slider toward the movable raft and located at the fourth guiding a connecting block in the slot, and a fungus block disposed on the connecting block and protruding outside the second guiding slot, the bumping block having a recessed groove nested in the inserting block. c S ) 6 1329552 The blocking member is mounted and fixed in the third guiding groove. The elastic member is mounted in the third guide groove for moving the block f unit in a direction opposite to the blocking member.
藉由上述組成，可以藉由該固定顎與該活動顎的夾置 面配合夾持定位一螺鎖件，當對該握柄施一順時針方向轉 動力，還可藉由該擋塊推壓該螺鎖件以順利帶動該螺鎖件 轉動，當對該握柄施一逆時針方向轉動力，則該擋塊會被 該螺鎖件推動朝向該阻塞件移動並解除該夾持定位，使本 發明棘動式活動扳手產生空轉而不會帶動該螺鎖件轉動， 藉此使本發明具有使用較方便的使用特性。 【實施方式】 本發明棘動式活動扳手前述以及其他技術内容、特點 與功效’在以下配合參考圖式之—較佳實施例的詳細說明 中，將可清楚的明白。With the above composition, the screw can be clamped and positioned by the clamping surface of the movable jaw, and when the handle is rotated in a clockwise direction, the screw can be pushed by the stopper.

Specifically, the 13295552 surface 82 and the third outer surface 83 are respectively clamped. It is respectively positioned by the clamping surface buckle and the 21-seat portion 432. Then the rotation force of the handle is applied to the needle to rotate (4) (4). When the screw member 8〇(4)(4)(4) is driven, the reverse force (10) of the movable seat 51 value toward the blocking member 6〇 is applied by the shifting ball 170: the block can be made 55 is applied to the screw member 8. - Push > 1 = the rotational efficiency of the screw member 80 is increased by the clockwise rotation of the screw member 80, as shown in Figs. 2, 6, and 7, When the handle 21 is applied to the reverse force, the stopper 55 is moved by the screw member toward the blocking member 60, thereby driving the guide groove 25), 1=1拄.兮 移动 ( ( I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I The side surface 83 is no longer being idling by the clamping surface wrench 2 (four) 'the ratcheting active rotation of the present invention, at this time, the elastic belt (four) screw lock buckle is generated back. (4) 70 疋 is collapsed The state is injurious and the returning elastic force is as shown in Figs. 4 and 5, and when the grip 21 is again applied, the force can be driven by the stopper:: force to drive the screw member 8 clockwise Directional rotation, =: push 434 can provide the screw lock # and then by the concave member ... advantageously rotate the gap in the clockwise direction = direction, the screw lock clockwise direction, thereby making the screw lock 8 10 rS ) S-outer side 81 again touches the The outer side surface 551 of the block 55, the outer side surface 82 and the third outer side surface 83 of the screw member 23 are respectively positioned by the clamping surface of the fixed jaw, and the convex arc clamping portion 432 of the movable display 43 is positioned, and then The tightening operation of the screw lock 80 can be continued. Further, as shown in Fig. 8, the ratcheting movable wrench 2 of the present invention is also applicable to a screw lock 90 of a smaller size. In summary, the ratcheting adjustable spanner of the present invention has the following advantages and advantages, so that the object of the invention can be achieved: because the present invention is formed by the clamping surface 231 of the fixed jaw 23 and the convex surface of the movable clamping surface 431. The arc clamping portion also cooperates to sandwich the screw locking member 8 - an outer side surface 82 and the third outer side surface 83, so that the screw locking member rib is clamped = vertical ' while blocking the screw locking member by the stopper 55 The first outer side of the 8 并 is: a pressure is applied to the screw member 80, so that the screw lock member can be rotated clockwise to perform the tightening operation, when the ratchet type adjustable wrench 2 is rotated, because the block 55 is moved by the screw member 8 () to move in the direction of the blocking member ' 'the screw member 8G is slightly rotated in the counterclockwise direction and is no longer clamped, so that the ratcheting wrench 2 is idling. The screwing member 80 is not rotated, and when the pawl movable wrench 2' is rotated clockwise again, the (4) screw member 8〇 can be pushed again by the automatic reset of the stopper 55, thereby making the screw member 8〇 is again clamped, thereby enabling the present invention to quickly clamp the screw 8〇, more convenient to use and efficacy advantages. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes made according to the scope of the invention and the description of the invention. Modifications, all 1325552 are still within the scope of the invention patent.
