Detailed Description

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1-4, the combined tool for clamping a wrench comprises a main body 1, a fixed jaw 2 is arranged at one end of the main body 1, and a movable jaw assembly 3 is slidably arranged in the main body 1. The movable jaw assembly 3 comprises a jaw seat 6 which is partially arranged in the main body 1 in a sliding manner, the main body 1 is provided with a guide elongated slot 4, and the jaw seat 6 is provided with a guide pin 5 matched with the guide elongated slot 4. The jaw seat 6 is provided with a jaw part 7, and the middle part of one side of the jaw seat 6 far away from the fixed jaw 2 is provided with a sliding adjusting seat 8 with a U-shaped section and buckled on the main body 1. The part of the jaw seat 6, which is positioned inside the main body 1, is provided with an installation gap, the jaw seat 6 is internally provided with an installation rod 9 which is parallel to the length direction of the main body 1 and penetrates through the installation gap, the part, which is positioned on the installation gap, of the installation rod 9 is rotatably sleeved with an adjusting worm 10, the main body 1 is provided with an avoidance elongated slot 11 which avoids the adjusting worm 10, the jaw seat 6 is provided with a guide slot 12 which is parallel to the length direction of the main body 1 and is communicated with the installation gap, a limit rack 13 which is matched with the adjusting worm 10 is movably arranged in the guide slot 12, the main body 1 is provided with a chute 14 for the movement of the limit rack 13, the limit rack 13 props against the fixed jaw 2 when a bolt and a nut are pulled;

the jaw seat 6 is located outside the main body 1 and is hinged with a short connecting rod 15 on one side far away from the fixed jaw 2, the end part of the short connecting rod 15 is hinged with a middle connecting rod 16, the end part of the middle connecting rod 16 penetrates into the sliding adjusting seat 8 and is movably hinged with a waist-shaped hole arranged on the sliding adjusting seat 8 along a position parallel to the limiting rack through a hinged shaft, the end part of the short connecting rod 15 is also provided with a locking handle 18 with a U-shaped section, and the locking handle 18 is rotated towards the main body 1 so that a hinged point between the short connecting rod 15 and the middle connecting rod 16 crosses the connecting line position of three hinged points on the short connecting rod 15 and the middle connecting rod 16. The locking handle 18 is hinged with a driving handle 19 which presses the middle connecting rod 16 to drive the short connecting rod 15 to rotate together so as to unlock the jaw seat 6. The middle connecting rod 16 is provided with a lug 17 matched with the driving handle 19 at the position close to the end part of the driving handle 19. The rear end of the driving handle 19 extends out of the locking handle 18.

A positioning ratchet bar 20 which is parallel to the length direction of the main body and is fully distributed with ratchets is arranged in the main body 1, a limit pawl 21 which is matched with the positioning ratchet bar 20 is hinged at the end part of the middle connecting rod, and a spring 22 which is in a stretching state when the jaw base 6 is in a locking state is arranged between the limit pawl 21 and the jaw base 6; the stretching state of the spring 22 generates a rotating force to the limiting pawl 21 to make the pawl teeth on the limiting pawl 21 firmly clamp the positioning ratchet bar 20.

The sliding adjusting seat 8 is provided with a clamp opening and unlocking mechanism which enables the limiting pawl 21 to be separated from the positioning ratchet bar 20. The unlocking mechanism for the pliers opening comprises an unlocking hole 23 formed in the sliding adjusting seat 8, a conical column 24 is movably arranged in the unlocking hole 23 in a penetrating mode, an elastic piece 25 pushing the main body to enable the conical column 24 to keep a popping state is sleeved on the conical column 24, a button seat 26 is arranged on the sliding adjusting seat 8, the thinner end of the conical column 24 is movably arranged in a penetrating mode in a connecting hole formed in the button seat 26, and an unlocking long hole 27 for enabling the conical column 24 to slide is formed in the main body 1.

When the movable jaw assembly 3 is used and moves towards the direction close to the fixed jaw 2, the driving handle 19 is pressed to enable the short connecting rod 15 and the middle connecting rod 16 to rotate so as to unlock the jaw seat 6, the spring 22 is in a natural state, and therefore the contact between the limiting pawl 21 and the positioning ratchet bar 20 is loose, and the movable jaw assembly 3 can move towards the direction close to the fixed jaw 2 as a whole;

when the movable jaw assembly 3 moves away from the fixed jaw 2, the limiting pawl 21 must be completely separated from the positioning ratchet 20 due to the action of the ratchet on the positioning ratchet 20, and the movable jaw assembly 3 can slide, so that the opening operation of the movable jaw can be realized only by pressing the driving handle 19 to rotate the short connecting rod 15 and the middle connecting rod 16 and pressing the tapered column 24 downwards to force the limiting pawl 21 to rotate to completely separate from the positioning ratchet 20.

When the clamping function is used, the limit rack 13 needs to be adjusted to the side away from the fixed jaw 2, then the driving handle 19 is pressed, the movable jaw assembly 3 is freely adjusted to clamp a workpiece, and then the locking handle 18 is rotated to lock the movable jaw assembly 3.

When the wrench is used, the limiting rack 13 is pushed to the fixed jaw 2 by rotating the adjusting worm 10, then the driving handle 19 is pressed down and the adjusting worm 10 is rotated, so that the movable jaw and the fixed jaw 2 clamp a workpiece to be wrenched under the condition that the limiting rack 13 is pushed against the fixed jaw 2, then the locking handle 18 rotates to lock the movable jaw assembly 3, wrenching operation can be performed, and the inconvenience that the workpiece needs to be readjusted when the workpiece is fastened by wrenching due to the fact that the movable jaw assembly 3 slides to the fixed jaw 2 in wrenching operation can be avoided.

The above-mentioned embodiments are merely illustrative of the principles and effects of the present invention, and some embodiments may be used, not restrictive; it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications belong to the protection scope of the present invention.
