Explanation of the new type: [Technical field to which the new type belongs] Cover J Creative Department! Γ gearboxes for electric tools, especially relevant-can be modified. Power tool gearboxes that often move gears. [Previous technology] In general, most electricians such as electric drills or electric screwdrivers are mostly designed to have a torque adjustment function At electricians "large. P needs _, 敕 + action 1 head A, so that it can be based on The actual operation == two forces. In addition, some electric tools can be used for hammering function (hammering function) = the operating output of Μ moving tools. For example, when making eight to change its front-end accessories and make _may When hunting, for example, if you want to install screws on the surface of a power tool ^ 2 ~ ~ a watch or a screwdriver, you can pull out the corresponding ', screwdriver f twist the front end of the power tool: The large torque wheel installed on the screw can damage the surface of the wood, and even cause the wood :::: f to run out of torque due to the output torque. When, for example, it is desired to break the screw teeth in the leeches 2 wood. The other side is equipped with the front end of the power tool: two holes are drilled two, then the corresponding output torque of the drill material can be adjusted beyond the maximum value. Two :: The power tool has an over-strike function, so that the drill will drill about the power tool to center it. Beiyue dagger is able to drill into a harder concrete wall. In order to adjust the torque of the wheel, the power tools are generally set at the purpose of its power = keystroke function. It is set between (such as a drill) ~ ", (D (Such as motors) and the operator of the wheel-out parts return to phase as the torque adjustment mechanism. By adjusting the torque adjusting sleeve provided on the outer side of the boxes by turning the ring, the 1818433 M274181 # 山 of the whole power tool can be rotated to different: bit = ,,. To achieve this, the torque adjustment sleeves output the various drill bits. When == the teeth are adjusted to the oldest with different torque output torque + 2 μ _ the entire sleeve is rotated to have the highest) < After asking the electric drill gear, adjust the gear box to the so-called "key hit 矜 right and then enter ^ If you turn it, you can hit the gear when you hit it. ”As mentioned above, when the gear box is out, it has the highest output torque that can provide the highest torque to the US patent 5,277,527. For example, the self-knowledge of the gear box of a power tool is shown below. The perspective view of the conventional display is shown in Figure 1 below. It should be noted here that the figure only shows the same as the original design, m AA, and the rest. In addition, Γ is a direct phase structure, and its related components. ^ The following is only detailed for the phase M of the institution directly aware of this creation. The adjustment of the characteristics and main points of the other exercises that interfere with the creation of 22 will be adjusted. Mechanism 1.

Shi Jianding resists the jumping MS. A torque adjusting sleeve is set on the adjusting ring to move; the torque 14 is along the cylinder. The axial direction of the part and the knock Ll are sleeved on the torque adjustment sleeve 15 and above, and are sequentially installed in the torque cover 16 with a '17 and 则 18 'series. The torque ㈣w mechanism It is fixed to the cylindrical part ring 14. The inner thread is formed on the inner side of the same part 5, and the adjuster rotates the twisted set to match the outer thread, so that when the cylindrical part is operated, When the axis ==, at least the spoon D · ϋ private movement σ 调整 can be adjusted along the system of the front case 11 of the gear box 14. In addition, the gear shift mechanism 7 gear box ^ f has a plurality of columnar positioning elements 71 ′ system Do not allow to place each of them :: a plurality of through holes (not shown) in the circumferential direction of the flange portion of the cymbal. Element 71, several bead-shaped positioning elements 72, respectively, are respectively associated with each columnar positioning ring, 7 ^ Gu Zhifang, in each through hole; and, the ratchet ring (ratchet) is placed in the receiving portion in the flange portion. 18433 7 M274181: The following will refer to the conventional power tool teeth shown in FIG. 2 A half cross-sectional view of one of the blades of the box is used to further explain the torque adjustment operation of the Xi mechanism. The torque adjustment u in the first phase has a cylindrical portion ⑴ and ― ~ connected to the cylindrical portion iu. In the part 1U, a through hole ii4 is opened to sigh the output main shaft 3 and some other components of the #box. In the convex = along; the Γ direction system is formed with a plurality of through holes (column two I t one) 'and Each through-hole 113 is sequentially provided with a positional element 71 and a bead-shaped positioning element 72, and the columnar positioning element ^^ and the positioning element 72 can only be axially opened along the through-hole 113 ^ In addition, 'the receiving portion 115 at the bottom of the flange portion 112 houses the coffin ring 73' wherein 'the slotted washer 73 has a ratchet shape On the top surface, a plurality of crotch portions are formed along the circumferential direction of the ring, and the top surface k abuts each bead-shaped positioning element 72. The flange portion 2 is provided with a jumper washer 12, a compression spring 13, and an adjustment ring. 14. The accommodation ring 141 is formed in the adjustment ring, and the adjustment ring M direction; move = to the bottom surface I42 abutting the shift washer 12, the compression bomb 13 can be completely accommodated in the accommodation portion ⑷ The jumper washer 12 has a surface 121 and a lower surface 122. When the adjustment ring 14 is moved to one of the axial directions of the cylindrical portion 111, the compression spring 13 is pressed due to compression. A dust elastic force is generated relative to the position and presses against the upper surface of the jump washer 12] 21. At this time, the Erhai jumper washer 12 will press the cylindrical positioning element abutting on its lower surface: and the bead-shaped positioning element 72 is pressed toward the ratchet-shaped top surface of the jumper ring 73. 18433 8 M274181 Force: In the gear box, the relevant parts are framed. When the lower surface 122 abuts on the top of the flange portion 112, the surface just abuts on the spine of the jump ring 73. The wheel-shaped top is formed into a region with a raised portion, so that the jumper ring 73 is caught. The force: the jumping mechanism of the tool and the deceleration mechanism are formed by, for example, the conventional structure: the Ding: silk mechanism: when the reverse torque transmitted by the output spindle 3 is ^ at the adjustment position with the adjustment ring 14 Corresponding expectations. The two bead-like positioning elements 72 can keep the jumping groove fixed; when the cymbal cover returned by the output spindle 3 is greater than the desired torque value, the jumping ring 73 will Driven by the phase and forcing the bead-like positioning elements to move and act I; II. That is to say, the speed of the groove-shifting operation of the groove-shifting ring 73 is two, and the adjustment is performed to achieve the purpose of torque control. With the adjustment of the gravity of the second flange, the shrinkage spring 13 will exert a compression elastic force on the jumping washer 12, resulting in ΜΜ; ρκι 73 $ It is difficult to place the bead-like positioning elements 72 on top. As a result, the field circle 73 is more private, and the jumper is generated from 7 to 7, which means that the lightning tool can have a greater torque output. I 卩 & When the highest groove of the conventional torque-adjustable electrician with keystroke function is adjusted, as shown in Fig. 2, the adjusting ring! The adjustment movement causes the adjustment ring to the torque chest:! When the upper surface 121 of the grooving washer 12 is in close contact, the specific switching mechanism (not shown) of "" will open "18433 9 M274181, so that the power tool will have a hammering function. ^ However, as mentioned above, when the conventional electric power tool is at the highest gear position, there is a substantially constant gap between the bottom surface 142 of the adjustment ring 14 and the upper surface 121 of the jump washer 12, $ That is, at this time, only the compression spring force of the contraction spring 13 is still used to press the jumper ring II: f: HAI clearance ™ is relatively large, it is easy to press the second; 〃 The pressure is insufficient, or the jump gear Partial deformation of the washer 12 results in the phenomenon of the skip ring 73, and the maximum torque that can be reached by the moving source can only be ...

It is known on the page of the jump washer that there are a plurality of raised portions, which form an ancient material clerk. In the 6th week of the shark mounting, a plurality of raised portions corresponding to the raised portion IMP, i 4 of the jump washer are also formed. When the top of the raised part abuts the top of the adjusting ring and the tools of the grooved ring are in contact with the top of the raised part, the electric box is at a low force, in other words, the power tool tooth is at this time Pad ::: Drilling. When the adjustment ring is further moved so that the raised portions of the washer and the adjustment ring are arranged in the same manner, and the jump washer is in contact with the bottom surface and / or two degrees, the page portion is When the top of the ring of the adjusting ring is connected to the top of the search protrusion with the top surface of the broadcast washer, the power tool is used. Take a large output torque and set it to have a hammering function, change t to hammering; P. 4, Shou " Yi Baodong tool gear box is located at the top of the raised parts of the electric drill gear box at the highest level of the ^ convex top of the ^ convex parts of the electric drill gear box is abutted on the adjustment, That is, no skipping phenomenon will occur. On the other hand, in terms of skin pushing force, since the jump file Π 18433 M274181 is not formed on the surface of the ring at this time, there is still ^ between the surfaces on which the protrusions are not formed. Therefore, when the gearbox of the electric tool is to be set into a step-and-step distance, it can be easily achieved. U When the gear is normalized, it can also be preferably the part of the jumper washer, and the circle neighbor The outer bucket surface has a plurality of convex weights. The outer peripheral surface is formed with a plurality of grooves to restrict the rotation of the groove. The groove can be kept in a fixed position so that = f . In this way, when the box is adjusted to the highest slot of the electric drill slot, = Ligong "is able to accurately abut the protrusions of the jump ring: the finding protrusions can accumulate teeth more than 22: Bu Zhou Part of the surface is formed with an outer inner screw tooth ::: two two! Is formed to match the outer screw tooth along the Xiyuan steam adjacent to Chan Er ^ Zheng Cuo by rotation relative to the cylindrical part of the field: . Hai η μ moves in the axial direction. In this way, when the electric :::: electric drill gear is switched to the hammer gear, due to the two, the raised rotations of the adjusting ring can be staggered from each other, so as to make it stand. Haisi Convex: =: =: / or the top of the raised parts of the adjusting ring and ;; to hammer ^ smoothly switch the power tool gearbox to the square T of the entire raised part of the raised part. Adjusting the ring diameter, the cross section of which = is normal is substantially trapezoidal, and the slope of the trapezoidal section-the slope, is much smaller than the slope of the other beveled side, and the slope with a smaller slope 18433 12 M274181 ΓΙΓ side The slope value corresponds to the slope of the screw teeth outside the cylindrical part = ,,, the diameter of the jump washer for each of the protrusions of the jump mark 塾, where 糸 is the slope on both sides is substantially equal Trapezoid. In this way, in turning the adjustment ^ 4ί, it is convenient to switch the gear box of the power tool from the highest-level package drill coffin to the hammered zi, pe ^ lifting of the private, the adjustment ring and the jump pad.} ^ _, The abutment between the beveled side of the protrusion U 卩 with a smaller slope and the protrusion 跳 of the jump pad, but a certain abutment force is always maintained. Hunting this, even if the operator does not broadcast, the electrician and the gearbox; with the gearbox positioned to the keystroke 0 phase will not jump gears and can keep the power tool =, s luck out. However, this creation is not limited to this, and the protrusion on the washer side of the jump gear can also be formed. The slope with one of the above hypotenuses is the slope of the far quarter 乂 and the other hypotenuse Those with a trapezoidal cross-section have 20% of the protrusions on the side of the adjustment ring, and have trapezoidal cross-sections with substantially equal slopes on both sides. Tt: 'The gearbox of the power tool has a jump gear mechanism, and the teeth of the tooth bearing the groove on the surface of the ring in the circumferential direction of the reunion α through hole, so that the jump washer through the plurality of through holes Pressing against the jump gear mechanism, the formation position of the plurality of through-holes in 14A ^ corresponds to the positions of the plurality of raised portions of the M port. In this way, when the gear box of the electric tool is at the highest level, the electric drill can produce a more stable and stable pressure-retaining door, which can ensure that no jump gear is generated. ]: Explain the embodiment of this creation with reference to the drawings.
