detailed description

In order to make the utility model more obvious and easy to understand, a preferred embodiment is described in detail below with reference to the accompanying drawings.

With reference to FIGS. 1 and 2, an easy-to-operate F clamp provided by the present invention includes a left clamp body, a right clamp body, and a guide rod 9.

The two ends of the guide rod 9 are respectively an elastic cylindrical pin 10-1 and an elastic cylindrical pin 10-2.

The left clamp body includes a left clamp case 1 and a left clamp case cover 5 fixed to the left clamp case 1 by screws 6-1. An installation space 1 is formed in the left clamp housing 1, a lock card 3 is installed in the installation space 1, and one end of the guide rod 9 is inserted into the lock card 3. One end of the button spring 2 is connected to the lock card 3, and the other end is connected to the left clamp housing 1. The lock card button 4 is in contact with the lock card 3, and the top surface of the lock card button 4 is exposed from the left clamp body through the through hole on the left clamp housing cover 5. A clamp pad 8-1 is fixed to the left clamp housing 1.

When the left clamp body needs to be operated, hold down the lock button 4 and the lock card 3 is driven downward by the lock button 4 until it is combined with the elastic cylindrical pin 10-1 at the end of the guide rod 9. At this time, the end of the guide rod 9 is locked with the left clamp body to ensure that the guide rod 9 can be moved when the left clamp body is pulled. After the card locking button 4 is released, the card locking 3 moves upward under the action of the restoring force generated by the button spring 2.

The right clamp body includes a right clamp housing 16 and a right clamp housing cover 7 fixed to the right clamp housing 16 by screws 2 6-2. An installation space two is formed in the right clamp housing 16, and in the installation space two are provided a shaft one 18, a shaft two 19, a toggle button 12, a splint one 13-1, a splint two 13-2 that cooperate with the toggle button 12, and Cam 11. The end of the handle 17 is threaded on the shaft 18 so that the handle 17 can be rotated around the shaft 18, and the remaining part of the handle 17 is exposed outside the right clamp housing 16. The cam 11 is threaded on the second shaft 19. The bottom of the cam 11 is provided with a slot that matches the shape of the end of the handle 17. The end of the handle 17 is inserted into the slot so that the handle 17 drives the cam 11 to rotate around the second shaft 19. A protrusion 11-1 is provided on the top of the cam 11, and a clamping groove is provided on the top of the cam 11. The toggle 12 and the splint 13-1 are located on the front side in the right clip housing 16, and the splint two 13-2 are located on the rear side in the right clip housing 16. The guide rod 9 passes through the trigger 12, the splint 1-13-1 and the splint 2 13-2. The edge of the part of the guide rod 9 located between the first clamping plate 13-1 and the second clamping plate 13-2 is matched with the cam groove. A part of the toggle button 12 is located outside the right clamp housing 16 to form an operation portion. One end of the lock spring 14 is connected to the clamp plate 13-1, and the other end is connected to the right clamp housing 16. One end of the splint spring 15 is connected to the second splint 13-2, and the other end is connected to the right clip housing 16.

The right clip housing 16 is fixed with a clip pad 8-2 that cooperates with the clip pad 8-1.

Under normal circumstances, the guide rod 9 is caught in the cam 11 slot, and the guide rod 9 is not easily moved by the left clamp body. When the guide rod 9 needs to be moved, the handle 17 is pulled to make the cam 11 rotate around the second shaft 19. The projection 11-1 on the cam 11 lifts the guide rod 9 upward, and at the same time, the guide rod 9 leaves the card slot. At the same time as the guide rod 9 is moved up, the trigger 12, the splint 1-13-1 and the splint 2 13-2 are moved upward. Because the guide rod 9 is disengaged from the slot, the guide rod 9 can be moved by the left clamp body. When it is in place, release the handle 17, the trigger 12, the splint 1-13-1 and the splint 2 13-2 are moved downwards by the lock spring 14 and the splint spring 15, and at the same time, the guide rod 9 is moved downwards. The cam 11 is caused to rotate in the reverse direction about the second shaft 19, and the guide rod 9 is re-engaged into the clamping slot under the action of the restoring force of the lock spring 14 and the cleat spring 15. In this process, the guide rod 9 can be assisted to re-engage into the card slot by operating the trigger button 12.
