As shown in fig. 3 and 4, the grip 2 includes an inner rod 21, a middle tube 22, and an outer tube 23.

The inner rod 21 is slidably connected to the inside of the middle tube 22, one end of the inner rod extends to the outside of the middle tube 22 and is fixedly connected with the clamp head 1, the other end of the inner rod is connected with a screw 24, and the other end of the screw 24 extends to a side far away from the clamp head 1. The screw 24 is rotatably connected to the end of the inner rod 21 and is movable in synchronization therewith.

The outer tube 23 is slidably sleeved outside the middle tube 22, and is fixed with the middle tube 22 through an adjustable limiting mechanism, and one end far away from the clamp head 21 is fixedly connected with the clamp handle 3. The tightness of the connection between the outer tube 23 and the middle tube 22 can be adjusted through the limiting mechanism, and when the tightness is loose, the position of the outer tube 23 relative to the middle tube 22 can be adjusted so as to change the length of the clamp handle 2.

Wherein the screw 24 is screwed with the middle tube 22, one end extends to the outside of the outer tube 23, and a turning handle 25 is provided at the end. The end of the outer tube 23 is provided with a through hole for the screw 24 to pass through. When in use, the screw 24 is rotated by rotating the handle 25, and the screw 24 drives the inner rod 21 to move relative to the middle pipe 22, so that the length of the clamp handle 2 is adjusted. The end of the middle tube 22 remote from the binding clip 1 is closed and a threaded rod 24 is threadedly connected to the closed end.

The grip 3 comprises a first bend 31, a second bend 32 and a handle 33. The first bending portion 31 is fixedly connected to the end of the outer tube 23, and is provided with an opening for the screw 24 to pass through. The second bending part 32 is rotatably connected to the top end of the first bending part 31, and the relative angle can be adjusted. The handle 33 is fixed to the top of the second bent portion 32.
