[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a quick-release wiper fastener, which has the following beneficial effects:

[0015] When the frame and the docking block need to be separated from the quick-release wiper fastener, the U-shaped piece is pulled, and the pull rope will provide a pulling force to the card block, which can cause the card block to compress the first spring. At this time, the card block will enter the first cavity and will be separated from the card slot. At this time, the docking block can be pulled out of the docking slot, and the docking block can be quickly disassembled from the frame, which can improve the efficiency of disassembling the docking block and the frame.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1-5The utility model discloses a quick-release wiper fastener, comprising a frame 1 and a docking block 2, wherein a docking groove 3 is provided inside the frame 1, and the docking block 2 can be inserted into the docking groove 3, and a first cavity 4 is provided on the inner wall of the docking groove 3, and a first spring 6 is provided inside the first cavity 4, and a clamping block 5 is provided at one end of the first spring 6, and a clamping groove 7 cooperating with the clamping block 5 is provided on one side of the docking block 2, and a U-shaped piece 8 and a second cavity 11 are provided at the rear end of the frame 1, and a second spring 12 is provided inside the second cavity 11, and a support rod 13 inserted into the second cavity 11 and connected to one end of the second spring 12 is provided on the U-shaped piece 8, and a pull rope 10 penetrating the first spring 6 and connected to the clamping block 5 is provided at both ends of the U-shaped piece 8;

[0024] In this embodiment, the docking block 2 can be fixed on the wiper strip, and the frame 1 can be fixed on the wiper driving rod. When the docking block 2 and the frame 1 need to be assembled, the docking block 2 is inserted into the docking groove 3. At this time, the first spring 6 can provide an elastic force to the clamping block 5. Through the cooperation between the clamping block 5 and the clamping groove 7, the docking block 2 and the frame 1 can be docked.

[0025] When the frame 1 and the docking block 2 need to be separated, the U-shaped piece 8 is pulled, and the pull rope 10 provides a pulling force to the card block 5, which can make the card block 5 compress the first spring 6. At this time, the card block 5 will enter the first cavity 4, which will make the card block 5 disengage from the card slot 7. At this time, the docking block 2 can be pulled out of the docking slot 3, so that the docking block 2 can be quickly disassembled from the frame 1, which can improve the efficiency of separating the docking block 2 and the frame 1;

[0026] When the U-shaped piece 8 is being pulled, the support rod 13 will stretch the second spring 12, thereby improving the stability of the U-shaped piece 8 when being pulled.

[0027] In order to make the docking block 2 more firmly installed in the docking groove 3 , the present invention is improved in that two first cavities 4 are symmetrically arranged on the inner wall of the docking groove 3 , and two clamping grooves 7 are symmetrically arranged on both sides of the docking block 2 .

[0028] In this embodiment, actuating pieces 9 are provided on both sides of the U-shaped piece 8 , and anti-slip grooves are provided on the actuating pieces 9 , so that the U-shaped piece 8 can be easily operated.

[0029] Furthermore, the docking groove 3 and the U-shaped piece 8 can be made of metal.

[0030] Furthermore, the two clamping blocks 5 have the same size.
