The push 70 is used to provide a force for moving the volute 50 toward the tooth row 41, which includes two springs. Ή The spring η is disposed in the two holes 64. In this embodiment, the shaft portion 51 is a rod body. Both ends of the rotating body are slidably received in the long groove, and the ends of the spring 71 are abutted against one end of the rod body. As shown in Fig. 5A and Fig. 5', the % of the occupant of the 蚂 〇 〇 可 can be selectively detached from the tooth row 41 (for example, when the user pulls the 蝎 50 downwards) Therefore, the movable element 4 can be quickly slipped when the merging portion 52 and the tooth row Μ are not in a merging relationship, thereby rapidly adjusting the opening size between the merging portion and the fixed cymbal, and further, when the engaging portion 52 and the tooth row 41 are When the meshing is performed, 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”. As shown in FIG. 6, the shank 1 of the adjustable wrench generally has an angle with the head 2, and since the squat 50 and the slide surface 23 of the present invention are also formed with a bevel angle, In this way, the radial direction of the salvage portion 52 (ie, perpendicular to the direction of the 埚m% 4) can be more parallel to the direction of the strip of the shank, so that when the user holds the thumb, the thumb In the direction of the arrow, it can be used more flexibly. 201103703 Rotating the volute 50 is more ergonomic. In addition, since the inclination angle Θ1 is not smaller than the front bevel angle 第一, when the user applies a force to turn a screw, the first surface 451 of the tooth portion 45 is sprayed as shown in FIGS. 7A and 7B. The front bevel 54 < the force F, the direction of the force f is perpendicular to the front bevel 54 , the force F can be divided into a horizontal component force fl and a vertical component force Ω, the horizontal component force fl The direction is parallel to the chute surface 23, and the direction of the vertical component force β is perpendicular to the chute surface 23, wherein the vertical component force 乜 is equal to Fxsine4' where the angle Θ4 = Θ1 - Θ2. Therefore, when the tilt angle Θ1 is greater than the front bevel angle Θ2, the dam 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 worm 50 can be more tightly engaged with the tooth row 41; and, when the tilt angle Θ1 # is at the front bevel angle θ2, the volute is not subjected to the wrench when the urging force is applied to the screw Any vertical component (due to sinG<M)), at this time, the force of the meshing portion of the fine mesh portion 52 is not affected by the force of the user to turn the screw; however, the inclination angle Θ1 of the field is smaller than the bevel angle ❸2 At this time, the dam will be subjected to the downward vertical component force f2 away from the slide surface when the movable wrench is forced to turn the screw firmware, that is, when the user turns the screw, the _ &5; The position of the force: use the ground and the tooth row 41 to disengage the relationship. At this time, the activity 颚4〇 lost the 3G's square snail _, which can not continue to pull the screw:: The point is that the angle must be Greater than or equal to 0 -7 ·. Does not spontaneously move away from the tooth. Where Ι θ4 卜 | 0 卜 0 is the angle between the front bevel and the imaginary line ,, (4) and e positive and negative sign; in other words 201103703, the age _ θ4 must be greater than or equal to the ,, _ e must be less than or equal to 0 degrees ' For example, in Fig. 7A, the θ is a negative angle. In the above example, the long slot system is opened on the arm ,, but the peripheral _ arm can also be used according to requirements. (4) The secret of the long slot ^ is directly opened and closed. The two sides of the groove 22 are also arranged to be slidably disposed at both ends of the rod body. Or, as shown in FIG. 9, the positioning unit 6q further includes a connecting portion 62 coupled between the pair of arms 61, and the pushing member includes two springs 71 and abutting a piece 72, the apex piece 72 is provided on the one side of the accommodating piece θ, and the other part of the apex piece is covered on a part of the merging portion 52, and the elastic π system is placed in the hole of the connecting portion 62. 64, inside. 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, such as a spiral magazine, and the shaft portion of the coupling portion 52 is provided at an axial center. The coil hole is provided for the coil spring, and the two sides of the accommodating groove 22 are respectively--the pin hole 81' is respectively fixed for fixing both ends of the coil spring; more specifically, the coil spring has a meshing portion The middle section of the 52-axis hole, which is just above 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 above-mentioned inclination angle 01 is not less than the design of the front bevel angle 02, that is, the crucible 4 must be greater than or equal to 〇, so that when the movable wrench pulls the screw, the 蝎m does not spontaneously disengage from the tooth row.
