The joint scale wire is slidably disposed in the accommodating groove, and the meshing portion is selective 2=direct salivation relationship. The row of teeth will be described below by way of a number of preferred embodiments to illustrate the use of the features of the present invention and the functions achieved by the present invention, and the scope of the invention can be described first. ...i [Embodiment] Please refer to Fig. 1 and Fig. 2. In the first embodiment of the invention, the active wrench = two (1): - head 2. - Fixed 颚 3. One live _ 4. , a worm clamping unit 60 and a pushing member 7 。. The handle portion 10 is for the user to hold, and the head portion 2 is disposed on the handle portion (7) = the base portion 20 has a sliding groove 21 and a "receiving groove 22". The sliding groove 2 is connected to the receiving groove, and is interconnected. That is, a pair of the chute surface 23 is formed on the top surface of the chute 21, and preferably, the 3 = joint groove 22 is formed into a square hole through the design of the head portion 2〇. Wherein, the 'moon trough 21' includes the largest diameter of the through-groove of the geometric shape. Although the embodiment only has a handle for driving the handle 10: the head of the firmware is 2, but the other end of the handle 10 can also be set to be the same as or different from the head according to requirements, to increase Use the elasticity. The fixed display 30 is fixed at one end of the head 2, and the live raft 4 has a row 4 and a pair of wires a which can be precisely matched with the slide surface 23, and the tooth row/the shoulder surface 42 Further connected to the connecting section 43; wherein the tooth row "is fit in the chute 21", more specifically, the tooth row 41 is accommodated in the trough 2ι through the trough, and the The connecting section 43 is disposed in the slot m, and the movable raft 40 is slidable along the extending direction of the chute surface 23 to approach or away from the fixed (four). Please refer to FIG. 3 for further steps. The row 41 has a first end 411 away from the fixed cymbal and a second end 412 adjacent to the fixed yoke 3, the second end of the tooth row 41 corresponding to the wearing surface corresponding to the traverse of the through slot, and the tooth The row 41 is tapered from the second end 412 toward the first end 411. Preferably, the row of teeth 4i has a top wheel hiding 413 and a bottom contour line 4M, and the top contour line 413 is located in the tooth row 4 The top end of the crucible is parallel to the chute surface 23, and the bottom wheel temple line 414 is located at the bottom end of the tooth row 41 ft and forms an inclined angle with the chute surface 23. Further defining the tooth Row 4 A plurality of notches 44 are formed in the surface, and a tooth portion 45 is formed between each two adjacent notches 44. Each of the tooth portions 45 has a first surface 451 facing the first end and a second end 412 facing the first end. The second surface is loose, and the direction of the teeth 45 is preferably the same as the angle of inclination between the slide surface 23, and the direction of the inclination is 'the closer to the second end of the tooth Μ, The further the distance from the slide surface ^ is. The worm 50 includes a shaft portion 51 and a substantially cylindrical engaging portion. The shaft portion 51 is disposed at the axial center of the engaging portion 52, and the shaft portion 51 and the slide portion A tilt angle Θ1 is formed between the face illusions, and the shaft portion 51 is closer to the slide surface 23 than the one end of the fixed 颚 30, that is, the tilt direction of the shaft portion 51. The locator 50 is slidably disposed linearly along the radial direction of the engaging portion 52 in the accommodating groove 22, 5 135 2006 and the saliva 4 52 system is selectively The ground is in an age relationship with the tooth row 4i. As shown in Fig. 4B, the merging portion 52 has a threaded coupling tooth, and the sputum scorpion 53 has a front bevel 54 and a rear Face &, the front bevel % is the top surface 451 of the tooth portion 45 of the live _ 40 when the movable wrench is turned, and the rear bevel 55 is slid in the direction of the movable display 40 away from the fixed ridge 3 When the second surface 452 of the tooth portion is pushed, the angle of the front inclined surface M is inclined to a front oblique angle of the front inclined angle 55. The angle of the imaginary line D is the rear oblique angle (four). The imaginary line D is a virtual line perpendicular to the direction in which the volute shaft portion 51 extends, that is, the imaginary line is parallel to the radial direction of the aging portion 52, wherein the front slanting surface and the movable spur portion 45 are the first side. 451 is at the top, so the first surface 451 also has an angle -2, and θ2 between the imaginary line D. Further, the inclination angle W is not smaller than the front bevel angle Θ2, i.e., the inclination angle Θ1 is greater than or at least equal to the front bevel angle Θ2. Moreover, the front and rear inclined faces 54, 55 of the 埚50 have a C-edge 54 551 away from the shaft portion η and a second root 542, 552 near the shaft 51. When the second side root 542 is closer to the imaginary line D than the first side tooth peak 541, the angle between the front slanting surface 54 and the imaginary line D is defined as a positive angle (as shown in FIG. 4B), and vice versa. When the first tooth peak 541 is closer to the imaginary line D than the second tooth root 542, the angle between the worm front bevel 54 and the imaginary line 疋 is a negative angle. Wherein, the imaginary line A is parallel to the top contour line and the slide surface, and the imaginary line B is perpendicular to the top contour line and the slide surface 假 imaginary line 平行 is parallel to the volute shaft portion, and the imaginary line D is perpendicular to 埚The um shaft part. Since the bevel angle 2 of the present invention is less than or equal to the inclination angle qi, it is already 1-352006. The foot is more than the positive angle of the bevel of the bevel before the forming, and the angle of the bevel 54 is more than the angle of the G. The negative angle is easier and the processing cost is relatively greatly reduced. Therefore, the front bevel angle θ2 is preferably a positive angle (greater than the twist). The positioning unit 60 is disposed in the accommodating groove 22, and the positioning unit 6 〇 includes a pair of arm portions 61 arranged in parallel, each of the arm portions amp having a long groove 63 ′ disposed along the extending direction thereof The lower phase of the long groove 63 is formed with a thin 64. The pushing member 70 is for providing a force for moving the volute 50 toward the tooth row 41, and includes two springs 7 and the second body 71 is disposed on the two holes 64 0 . In this embodiment, the shaft portion 51 is a rod body, and both ends of the rotating body are slidably received in the long slot, and the ends of the springs 71 are abutted against one end of the rod body. As shown in FIGS. 5A and 5B, since the meshing portion 52 of the present invention can select the I1 ground and the tooth row 41 to be disengaged (for example, when the user pulls the coke % down), the two are separated. 'Therefore, the activity 颚4〇 can be slid in the non-salting relationship between the shouting portion 52 and the tooth row 41, _ fast_the size of the opening between the oil (four), and in addition, when the engaging portion 52 meshes with the tooth row 41 At the same time, the position of the movable 颚4〇 can be finely adjusted by turning the volute 50, and it can be seen that the adjustable wrench of the present invention has the functions of “quick adjustment and fine adjustment”. Further, as shown in Fig. 6, the handle portion 1 of the adjustable wrench is generally at an angle with the head portion 2, and a tilt angle is formed between the worm 5 〇 and the slide surface 23 of the present invention. In this way, the radial direction of the salvage portion 52 (ie, the direction perpendicular to the axis portion of the volley 50) can be more parallel to the longitudinal direction of the shank portion 1 , which is advantageous when the user holds the handle. The thumb (the direction indicated by the arrow in the figure) can be applied more forcefully. 7 1352006 Rotating the 埚50 is a more ergonomic design. In addition, since the inclination angle Θ1 is not smaller than the front bevel angle Θ2, when the user applies a force to turn a screw, the first face 451 of the tooth portion 45 is engaged as shown in FIGS. 7A and 7B. The front bevel 54 of the tooth 53 is a force F, and the direction of the force F is perpendicular to the front bevel 54. The force F can be divided into a horizontal component force f1 and a vertical component force f2, and the direction of the horizontal component force fl is Parallel to the chute surface 23, the direction of the vertical component force f2 is perpendicular to the chute surface 23, wherein the vertical component force β is exactly equal to Fxsin04' where the angle Θ4 = Θ1 - Θ2. Therefore, when the tilt angle Θ1 is greater than the front bevel angle Θ2, the worm can receive an upward vertical component force β toward the slide surface when the adjustable wrench applies the force to turn the screw, that is, when the user turns the screw The greater the force, the meshing portion 52 of the 蝎50 can be more tightly engaged with the tooth row 41; and when the slant angle Θ1 is equal to the front angle θ2, the 埚m does not receive any force when the adjustable wrench urging plate turns the screw Vertical component force (due to ϋ), at this time, the force of the _5() spray 52 splicing tooth row 41 is not affected by the force of the user to turn the screw; and 'when the tilt angle Θ1 is smaller than the front slant ± plate Turn the screw solid (four) to receive - away = ^ 'Rum will be in the hand of the miscellaneous hand · Old Tie cat face down vertical component force f2, even if j action ^ firmware when the _5G hobby part 52 will be subject to The vertical force Wei and Lai 41 miscellaneous _ sin and away from the fixed 颚 3 〇 一 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Therefore, the focus of the present invention is on = two, and the snail is pulled [degrees, _ _ 5. It does not spontaneously move away from the angle ridge greater than or equal to the e is the front bevel and the imaginary. (4) Quasi-Θ4 and θ positive and negative sign: change] t, since the ant colony β4 must be larger than the scale ο degrees, _ e must be less than or equal to the twist, for example, in Figure 7A, the θ is the negative angle. In the above-mentioned real k example, the long trough system is opened on the arm portion ^, but it can also be found in the south, and the arm portion 6 and the butterfly 8 are displayed in the vertical direction. Both sides of the groove 22 can also be slidably disposed at both ends of the rod body. Alternatively, as shown in FIG. 9 , the positioning unit 60 may further include a connecting portion 62 that is coupled between the blanks 61 and a portion of the negative pushing member that includes a spring 71 and an abutting sheet 72. The apex piece 72 is provided with a portion of the top surface of the yoke portion 62, and the spring 71 is disposed in the hole 64 of the connecting portion 62. . In addition, as shown in FIGS. 10A and 10B, the shaft portion 51 of the present invention may also be a support member having flexibility and elastic restoring force, for example, a coil spring, and the shaft portion of the spray portion 52 is provided with a shaft. The hole is provided for the coil spring to be disposed on the two sides of the accommodating groove 22, and the contact hole 8 is respectively accommodated at both ends of the service spring; more specifically, the coil spring has a shaft hole located in the engaging portion 52. In the middle section, the middle section abuts against the side wall of the shaft hole. Thereby, the worm 5 〇 can also be linearly slid in the accommodating groove and selectively disengaged from the tooth row 41. In summary, the volute and the tooth portion of the present invention are inclined to the slide surface, so that the user can rotate the volute more naturally, and the movable wrench of the present invention is more ergonomic. Moreover, the inclination angle 01 is not less than the design of the front bevel angle Θ2, that is, the Θ4 must be greater than or equal to 〇, so that when the movable wrench pulls the screw, the volute does not spontaneously disengage from the tooth row. Moreover, since the oblique angle is less than or equal to the inclination angle before the 135, 2006, the angle of the previous oblique angle may be a positive angle to facilitate the processing. Therefore, the adjustable wrench of the present invention is a novel and practical element that falls within the scope of the prior art, and is not easily completed by those having ordinary knowledge in the field, and complies with the relevant provisions of the national patent law, and is requested to be approved by the bureau.
