On the basis of the technical scheme, the utility model discloses still provide following optional technical scheme:

in one alternative: set up port and port department on the quick-open clamp lateral wall and be provided with the locking mechanism who locks it on gripping the handle, locking mechanism is including running through the screw rod at quick-open clamp both ends, and nut and screw rod other end are provided with the carrying handle are installed to screw rod one end.

In one alternative: the side wall of the quick-opening clamp far away from the port of the quick-opening clamp is provided with a fixing hole for fastening and connecting one end of the chain through a pin shaft.

In one alternative: the holding handle is close to the top of the chain and is flat, and a 30-degree groove is formed in the center of the top of the holding handle.

In one alternative: the top end part of the holding handle is also provided with anti-skid teeth.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the space between the chain and the holding handle can be adjusted by the movement of the quick-opening clamp on the holding handle in the wrench so as to adapt to wrenches with different sizes; the tail end of the chain is provided with a quick-release clamp, the pulling fastening force is strong, and the chain is convenient to move and lock quickly.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural view of a locking mechanism of the medium-speed opening clamp of the present invention.

In the figure: the quick-opening clamp comprises a holding handle 1, a chain fixing rod 2, a chain 3, a quick-opening clamp 4, anti-skidding teeth 5, a nut 6, a screw 7, a carrying handle 8 and a fixing hole 9.

Detailed Description

The present invention will be described in detail with reference to the following embodiments, wherein like or similar elements are designated by like reference numerals throughout the drawings or description, and wherein the shape, thickness or height of the various elements may be expanded or reduced in practical applications. The embodiments of the present invention are provided only for illustration, and not for limiting the scope of the present invention. Any obvious and obvious modifications or alterations to the present invention can be made without departing from the spirit and scope of the present invention.

Example 1

Referring to fig. 1 and 2, in an embodiment of the present invention, a novel universal chain wrench includes a holding handle 1, a chain fixing rod 2 and a chain 3, wherein the chain fixing rod 2 is fixed at one end of the holding handle 1, one end of the chain 3 is fixedly connected to a side wall of the chain fixing rod 2 near an end portion thereof, the holding handle 1 is provided with a quick-opening clamp 4 capable of sliding and fastening thereon, the other end of the chain 3 is connected to a side portion of the quick-opening clamp 4, and a locking space for clamping a workpiece is formed between the holding handle 1 and the chain 3;

the side wall of the quick-opening clamp 4 is provided with a port, the port is provided with a locking mechanism for locking the quick-opening clamp on the holding handle 1, the locking mechanism comprises a screw 7 penetrating through two end parts of the quick-opening clamp 4, one end of the screw 7 is provided with a nut 6, and the other end of the screw 7 is provided with a handle 8; the screw 7 can be loosened by rotating the handle 8, the quick-opening clamp 4 is loosened or fastened on the holding handle 1, and the handle 8 is pressed towards the handle after the screw 7 is in place, so that the quick-opening clamp can be firmly locked;

a fixing hole 9 for tightly and fixedly connecting one end of the chain 3 through a pin shaft is formed in the side wall of the quick-opening clamp 4 far away from the port of the quick-opening clamp;

the top of the holding handle 1 close to the chain 3 is flat, and a 30-degree groove is formed in the center of the top of the holding handle 1, so that the holding handle 1 can be used for quickly pressing and loosening workpieces; the top end part of the holding handle 1 is also provided with anti-skid teeth 5; the arrangement of the anti-slip teeth 5 can effectively prevent the workpiece from slipping, so that the wrench of the chain 3 can bind the workpiece more firmly;
