A ratchet wheel 30 is rotatably disposed on the first housing 13 along the axis of rotation L. The mounting surface 31 and the set of surface 32 are respectively disposed at two ends of the ratchet wheel 30 toward the rotation axis L. The sleeve surface 32 faces the ratchet wheel 30. A bottom portion 321 is protruded from the inner periphery. The inner side surface of the first body 10a and the inner side surface of the second body 10b are respectively disposed opposite to the mounting surface 31 and the sleeve surface 32 such that the ratchet wheel 30 is disposed between the first body 10a and the second body 10b, wherein the ratchet wheel The outer peripheral ring of the 30 is provided with a plurality of ratchet teeth 33, and the inner periphery of the ratchet wheel 30 is provided with a fixed clamping portion 34.

A ratchet device 40 is disposed in the second pocket 14 for engaging the ratchet teeth 33. When the grip 20 is turned, the ratchet teeth 33 of the ratchet wheel 30 and the ratchet device 40 can mesh with each other to rotate the ratchet wheel 30. In the embodiment of the present invention, the ratchet device 40 can change the direction of rotation of the ratchet wheel 30.

A positioning member 50 is locked to the mounting surface 31. A first card portion 51 is disposed on a side of the positioning member 50 facing the mounting surface 31. The first card portion 51 is disposed in a radial direction relative to the rotation axis L. The first card portion 51 has a rack shape.

A sliding sleeve 60 is disposed on the inner circumference of the ratchet wheel 30. The first surface 61 and the second surface 62 are respectively disposed on the two ends of the sliding sleeve 60. The first surface 61 corresponds to the mounting surface 31. The second surface 62 is correspondingly disposed toward the sleeve surface 32. The first surface 61 is recessed with a receiving groove 611, and the second surface 62 is recessed with a contact portion 621. The contact portion 621 is slidingly contacted with the bottom portion 321.

A movable member 70 is disposed in the accommodating groove 611 and is movably connected to the positioning member 50. The movable member 70 is movable between a first state, a second state and a third state, wherein the movable member 70 is implemented in the present invention. In the example, the shape of the receiving groove 611 corresponds to the shape of the movable member 70. The movable member 70 has a movable clamping portion 71. The movable clamping portion 71 has a V shape, and the movable clamping portion 71 and the fixed clamping portion 34 correspond to each other and form a tool slot 80 therebetween to provide the workpiece 1 in a nest. In the embodiment of the present invention, the tool slot 80 is interposed between one side of the sliding sleeve 60 and the fixed clamping portion 34.

The movable member 70 is provided with a second card portion 72 corresponding to the first card portion 51. The second card portion 72 and the first card portion 51 can be mutually locked, and the second card portion 72 is disposed in the radial direction along the rotation axis L. In the embodiment of the invention, the second card portion 72 has a rack shape, and the first card portion 51 and the second card portion 72 are engaged with each other, and the tooth portion of the first card portion 51 is longer than the tooth portion of the second card portion 72. Furthermore, one side of the movable member 70 is provided with a pushing portion 73. The pushing portion 73 is raised above the positioning member 50 and protrudes from the outer side of the first body 10a via the first receiving groove 13.

Furthermore, the movable member 70 is recessed toward a side surface of the sleeve surface 32, and a receiving groove 90 is disposed in the receiving groove 74. The receiving member 90 is disposed between the movable member 70 and the sliding sleeve 60. In the embodiment of the present invention, the holding member 90 is made of an elastic material, and the two ends of the holding member 90 are respectively abutted between the receiving groove 74 and the sliding sleeve 60. The holding member 90 can keep the contact portion 621 in contact with the bottom portion 321 .

In addition, in another embodiment of the present invention, the ratchet wheel 30 is provided with two positioning members 50. The two positioning members 50 are respectively disposed on two sides of the mounting surface 31, and the movable member 70 is movably disposed between the two positioning members 50. Each of the two first card portions 51 corresponding to the two positioning members 50 is provided with a second card portion 72, and the movable member 70 is recessed with a receiving groove 74 corresponding to each of the two positioning members 50. Each of the 74s is provided with a top member 90.

In the first state, the elastic tension of the holding member 90 keeps the second clamping portion 72 of the movable member 70 in engagement with the first clamping portion 51 of the positioning member 50 in the axial direction of the rotation axis L, as shown in the figure. 2 and Figure 4.

In the second state, the movable member 70 is movable in a direction parallel to the rotation axis L. In the embodiment of the present invention, when the operator applies the force to the pushing portion 73 in a direction parallel to the rotation axis L, the movable member 70 can be The direction of the force is moved so that the second card portion 72 and the first card portion 51 are no longer engaged with each other; and when the force is applied by the operator to the pushing portion 73, the elastic tension of the holding member 90 makes the activity The piece 70 automatically returns to the first state from the second state, see Figures 2 and 5.

In the third state, the movable member 70 can slide in a direction perpendicular to the rotation axis L to adjust the size of the tool slot 80. In the embodiment of the present invention, when the operator moves the movable member 70 to the second state, The urging portion 73 is biased in a direction perpendicular to the axis of rotation L to adjust the size of the tool slot 80. The movable member 70 moves while driving the sliding sleeve 60 to move in the direction of the force, and the contact portion 621 of the sliding sleeve 60 slides. The bottom portion 321 is contacted, thereby increasing the strength of the movable member 70 and preventing the movable member 70 from being damaged by an external force. Please refer to FIG. 2, FIG. 3 and FIG.

Therefore, when the operator wants to lock or loosen the workpiece 1, the tool slot 80 is sleeved on the workpiece 1 by the sleeve surface 32, so that one side of the workpiece 1 is placed on the fixed clamping portion 34, if the tool slot 80 When the size does not match the size of the workpiece 1, the operator can apply a force to the pushing portion 73 in a direction parallel to the rotation axis L, so that the movable member 70 changes from the first state to the second state; then, the operator again Applying the force to the pushing portion 73 in the direction of the rotation axis L, and changing the movable member 70 to the third state, the size of the tool slot 80 can be changed to match the size of the workpiece 1, so that the workpiece 1 is fixedly clamped and movable. The portion 71 is clamped; then, the grip 20 is rotated to rotate the ratchet 30 to perform the work of locking or loosening the workpiece 1.

Thereby, the movable member 70 is movably connected and moved with the positioning member 50 to match the size of the workpiece 1 to adjust the size of the tool slot 80, and after the resizing, the workpiece 1 is locked or loosened by rotating the ratchet 30. It can be used with workpieces 1 of different sizes, and can be combined with quick screwing or loosening, which increases the utility and convenience of the present invention.
