The left end of the movable rod 203 is fixedly connected to a push plate 204, the right end of the movable rod 203 is fixedly connected to a limiting plate 205, and the left side of the push plate 204 is fixedly connected to a toggle plate 206. The inner wall of the positioning frame 201 is slidably connected to a top plate 207, and the right side of the top plate 207 is fixedly connected to a bearing sleeve 208, and the movable rod 203 is rotatably connected to the inner wall of the bearing sleeve 208, and four springs 209 are fixedly connected to the right side of the top plate 207.

[0024] Furthermore, the push plate 204 and the limit plate 205 are respectively matched with the two rectangular through holes and the transverse slot. The push plate 204 and the limit plate 205 can respectively pass through the two rectangular through holes and be inserted into the transverse slot for positioning.

[0025] Furthermore, the length of the toggle plate 206 is smaller than the width of the rectangular through hole. After the push plate 204 is inserted into the transverse slot, the toggle plate 206 is at the rectangular through hole position and will not be inserted into the transverse slot, making it convenient for the user to pass his hand through the rectangular through hole and twist the toggle plate 206.

[0026] Furthermore, one end of the spring 209 away from the top plate 207 is fixedly connected to the right inner wall of the positioning frame 201. The top plate 207 can drive the spring 209 to deform. At the same time, after the push plate 204 and the limit plate 205 are inserted into the transverse slot, the reaction force generated by the spring 209 can press them in the transverse slot, and the stability is relatively high.

[0027] Furthermore, the adjustment component includes a strip plug plate 101, and the upper surfaces of the two strip plug plates 101 are each provided with a plurality of threaded through holes, and the backs of the first connecting member 2 and the second connecting member 3 are each provided with a strip groove adapted to the strip plug plate 101, and the U-shaped connecting member 1 can be inserted into the strip grooves of the first connecting member 2 and the second connecting member 3 through the front strip plate 101 to flexibly adjust the overall length.

The vertical plate 102 on the front of the strip plug plate 101 can slide in the slide groove, and the positioning block 103 can slide in the limiting groove and be limited by the limiting rod 104 to ensure that the C-shaped connector 1 will not be separated from the first connector 2 and the second connector 3, thereby ensuring the clamping effect of the clamp.

After putting them on, push the push plate 204 to the right, so that the push plate 204 drives the top plate 207 and the limit plate 205 to move to the right through the movable rod 203. During the process of the top plate 207 moving to the right, the spring 209 can be squeezed to deform it. At the same time, the push plate 204 and the limit plate 205 can pass through the rectangular plate 202 and the positioning plate 301 respectively. After passing through, the toggle plate 206 is twisted to make the push plate 204 drive the limit plate 205 to rotate ninety degrees through the movable rod 203. At this time, the push plate 204 is released, and the push plate 204 and the limit plate 205 are subjected to the reaction force generated by the spring 209. , respectively inserted into the horizontal slots on the right side of the rectangular plate 202 and the positioning plate 301, thereby completing the limit locking of the entire clamp. When the required clamping position is different in size, the locking bolt 105 is turned to disengage it from the threaded through hole on the strip plug plate 101. At this time, the U-shaped connecting piece 1 is pulled backward to drive the two strip plug plates 101 to expand backward. The strip plug plate 101 is affected by the vertical plate 102, the positioning block 103 and the limiting rod 104, and will not be separated from the first connecting piece 2 and the second connecting piece 3. When adjusted to a suitable length, the locking bolt 105 is inserted into the threaded through hole on the strip plug plate 101 to lock the strip plug plate 101 and complete the adjustment of the entire clamp length.
