New description: [New technical field] This creation involves the removal of belt technology for automobile repair, especially a time-regulating pulley retaining device. [Prior Art] The timing pulley is mounted on the camshaft and crankshaft of the engine to determine the opening and closing of the valve to avoid bending, deforming or damaging the piston. These timing pulleys are meshed with the timing belt to drive the camshaft and the crankshaft to rotate synchronously, so the timing belt is directly related to the timing or sequence of opening and closing of the valve. The timing belt is also called the timing belt. The main material is rubber. It has physical properties such as aging and fracture. It needs regular inspection and renewal to extend the service life of the vehicle. When replacing the timing belt, it is necessary to pay attention to the relative relationship between the timing pulleys, and it is not appropriate to produce excessive deviation to ensure the timing of the valve opening and closing. If there is a deviation between the timing pulleys, the power of the engine power is relatively reduced, and the power can be readjusted by the correction means, but the trouble is increased. The heavy engine or other transmission components damage the driving safety. For the subject of this car repair, the traditional practice is to remember the mark of the old time gauge belt marked on the outside, and the position of the timing pulley relative to the mark, according to which the new belt is placed around the periphery of each wheel; due to the accuracy After getting the guarantee, it is necessary to turn the timing pulley several times before you dare to start the engine, which is quite troublesome. In the recent practice, during the replacement of the timing belt, a three-type retaining device is used to protect the relative relationship between the timing pulleys, so that the wheel body is maintained in a non-rotating state and then the belt is removed, so that the camshaft is timed. The external force affects and rotates arbitrarily. Such a retaining device dedicated to the timing belt removal has been disclosed in U.S. Patent No. 6,332,256, the "HGldingDeviee" patent: ^The retaining device comprises a connecting piece and two pairs of retaining blocks, each pair of retaining blocks being bolted - The active tooth block and the movable tooth block pass through the handle of the connecting piece® hole and the elongated hole, and each pair of moving tooth blocks. Different manufacturers produce models, the distance between the camshaft and the crankshaft is different' plus the difference in the diameter of the pulley, the surrounding: the teeth are also inconsistent, the bolt and the handle need to be loosened, the active tooth block With the movable tooth block, the whole ', Temple 1 is quite loose, and it is easy to fall by gravity. : times, within the limit of the elongated hole, push a pair of retaining blocks = when the position ' let the active, movable and other teeth block the belt, lock the bolt to keep the movable block still, then tighten :: The state of the J-moving toothed belt pulley is quite cumbersome and necessary for improvement. [New content] To thank the & item "This creation uses the means of limiting the swing: the use of:: lack: Tang Li: t keep the rod stuck in the pulley around the continuous replacement of the fast and convenient angle of attachment, with The belt retaining device achieves the above purpose, and the holding device of the present invention comprises: ^82213 two pairs of holding jaws respectively, which are respectively engaged with the edge of the pulley; = fixed rods are fixed from the position; - the movable arm is coupled to the connecting member and can be attached mobile. The movable member has a difficult structure for holding the rod, wherein the connecting member has two recessed portions, the recessed portion is circumferentially and the gentleman is walled, and the restricting wall is adjacent to the edge of the connecting member=the opening direction of each recessed portion is the same as or opposite; The movable arm ^ ^ is side by side and locked on the connecting member, and can be loosely rotated, and the wall is blocked. Secondly, the adjustment structure is a through-slip and is moved and locked to the movable arm in the squat-flat section and the undulating section. In this way, as long as the screw is released, the activity can be: within a predetermined range, that is, the width of the opening of the wall is restricted, so that the protection is in the continuous tooth around the V wheel, and then the screw is locked. : The wheel body does not rotate easily. Even, the rod that is locked to the movable arm is loose, 'moving to the position closest to or farthest from the connecting member, and the different effect of the timing of the skin 彳 V V 。 。 。 。. The following = the technology, means and efficacy of the use of the Π , 兹 兹 兹 兹 兹 b & & & & amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp 相信 相信 amp 相信 amp 相信Modes Hereinafter, related embodiments will be described in detail based on the drawings. Referring to Figures 1-2, the retaining device 10 of the drawing is similar to the squeezing tongs, and the two movable arms 30: 5 are locked in the middle of the connecting member 20 and are held on the holding lever 4. The periphery of the part is limited to _22,1—= The edge of the joint 2〇 is formed in the direction=艮^22 is immediately adjacent to the 5〇 insertion through the depression (4) = 2^^50 and 4::3. The end gas is listed in the recess 21, and the nut 51 of the screw member is threaded through the sliding hole. The movable arm 30 passes through the flat section 32 and the undulating section 33, and is recessed by a large width of the resisting portions % and the second, which cannot be arbitrarily rotated. /, 匕 (4) 51 is placed in the undulating section 33 but the piece 20: the two pairs of holding rods 4 〇 are in the shape of a stick, and are tightly inserted into the ends of the connecting member 20 and are not movable. The pair of holding rods 40 are similar to the bolt shape. The other head 4! and a screw adjacent to the head 41, after the sliding hole 31 of the movable arm 30, the lock is again passed through the cap-interference: arm: tight = moving and locking characteristics , called the movable retaining lever buckle. When it can be used, the retaining device 1" is pivoted with the screw member 50 as the axis, and the swinging wall 22 and the opening = the inner flexible swing. As shown in Figs. 3 and 4, the continuous tooth 61 around the wheel 60 When the gully core is formed: the fixed retaining rod 40 at the end of the connecting member 2, and then the two: the moving arm 3 移动 is moved toward the timing pulley 60, so that the movable body can be inserted into the other tooth groove 62. , then tighten the screw 5. =! Can not be fixed, to stop the timing pulley 60, the belt b is smoothly replaced on the monthly b. The rotating gauge pulley. 60 the number of teeth is different 'auto repair personnel can: = head The portion 41, which will release the retaining rod 4. The guiding of the two walls is moved in the smoothing section 32 and the undulating section 卡 to engage in the groove 62 of the timing pulley 60, and then tighten the head 41 of the retaining rod 40. The whole process 'in principle, only need to use the % of the fittings, can = stop the effect of the timing pulley 60 rotation. Unless the diameter of the two belts of the timing belt is different or the number of teeth is increased or decreased, the activity is required. The holding rod 40 is more convenient, faster and faster than the prior art. f, the above examples are only illustrative The present invention is not limited to the present invention. Various changes, modifications, and applications derived from the above embodiments are within the scope of this creation.
