[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments of this disclosure to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0022] The gap between the claw end of the head air curtain fixing clip and the inner wall of the clip is small, making it difficult to insert with ordinary pliers. To facilitate the removal of the fixing clip, this utility model provides a tool for removing the head air curtain fixing clip. (See reference...) Figures 1-3 As shown, the device includes two clamp bodies hinged together by a hinge 3. Each clamp body includes a clamp head 1 and a handle 2. The clamp head 1 includes a bending head 11 and a connecting head 12. One end of the connecting head 12 is connected to the handle 2, and the bending head 11 is located at the other end of the connecting head 12 away from the handle 2. The bending head 11 is bent along the axis of the hinge 3. The bending head 11 includes a clamping part 111, the size of which is smaller than the gap between the tail of the clamping claw and the inner wall of the clamp. When disassembling the head air curtain clamping claw, the clamping part 111 can extend into the gap of the clamp to clamp the tail of the clamping claw, quickly tightening the clamping claw support part and detaching the clamping claw support part from the vehicle body sheet metal, thus achieving rapid disassembly.

[0023] In one embodiment, such as Figure 2 As shown, the longitudinal section of the clamping part 111, which extends in the same direction as the bending head 11 and intersects with the plane containing the clamping surface of the clamping part 111, is set to a rectangle. This allows the clamping part 111 to extend uniformly from its free end toward the connector head 12, which can increase the strength and rigidity of the clamping part 111 and facilitate clamping the tail of the clamping claw of the fixing card.

[0024] For ease of description, the gap between the claw tail of the fixing card and the inner wall of the fixing card can be simply referred to as the fixing card gap or gap. The size of the clamping part 111 is smaller than the gap size between the claw tail of the fixing card and the inner wall of the fixing card. Specifically, the thickness of the clamping part 111 is smaller than the thickness of the fixing card gap, and the width of the clamping part 111 is smaller than the width of the fixing card gap. The gap width between the claw tail of the fixing card and the inner wall of the fixing card is slightly greater than 4mm, and the thickness is approximately 0.85mm. Therefore, the thickness of the clamping part 111 is no greater than 4mm, and the width of the clamping part 111 is less than 0.85mm.

[0025] In one embodiment, such as Figure 2As shown, the thickness d1 of the clamping portion 111 is set to 0.7-0.8 mm, for example, the thickness d1 of the clamping portion 111 can be set to 0.7 mm, 0.71 mm, 0.72 mm, 0.73 mm, 0.74 mm, 0.75 mm, 0.76 mm, 0.77 mm, 0.78 mm, 0.79 mm or 0.8 mm, etc. The clamping portion 111 is set to an appropriate thickness d1, which is convenient for the clamping portion 111 to be inserted into the gap between the tail of the clamping jaw of the fixing card and the inner wall of the fixing card, and can maintain the rigidity of the clamping portion 111, which is convenient for the clamping portion 111 to clamp the tail of the clamping jaw of the fixing card and apply force, so that the supporting portion of the clamping jaw of the fixing card is retracted.

[0026] In one embodiment, as shown in Figure 3 As shown, the clamping surface of the clamping portion 111 is set to a trapezoidal shape, and the upper base of the trapezoidal shape is arranged at the free end of the clamping portion 111, so that the free end of the clamping portion 111 is smaller than the gap of the fixing card, which is more convenient for the clamping portion 111 to be inserted into the gap of the fixing card. Preferably, the length d2 of the upper base of the trapezoidal shape is set to 3-4 mm, for example, the length d2 of the upper base of the trapezoidal shape can be set to 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm or 4 mm, etc.

[0027] In one embodiment, as shown in Figure 3 As shown, the length L1 of the clamping portion 111 is set to 13-18 mm, so that the clamping surface of the clamping portion 111 extending into the gap of the fixing card is sufficient, and the clamping portion 111 can stably clamp the tail of the fixing card and facilitate force application. For example, the length L1 of the clamping portion 111 can be set to 13 mm, 14 mm, 15 mm, 16 mm, 17 mm or 18 mm, etc.

[0028] In one embodiment, the extension direction of the bending head 11 and the extension direction of the connecting head 12 have an included angle α, and the included angle α is set to 30-45°, which avoids interference between the tool and the vehicle body during disassembly and facilitates operation. For example, the included angle α can be set to 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°, etc.

[0029] In one embodiment, the bending head 11 further comprises a transition portion 112, which is set to a truncated cone, the small end of which is connected to the clamping portion 111, and the large end of which is connected to the connecting head 12, which can strengthen the strength of the bending head 11.

[0030] In one embodiment, the length L2 of the bending head 11 is set to 20-30 mm, which can maintain sufficient length L1 of the clamping surface.

[0031] The head air curtain is installed at a certain angle with the vehicle body panel, and the head air curtain fixing clamp is an elastic component, and during installation, the left and right clamping jaw support portions of the fixing clamp are respectively resiliently opened to firmly clamp the vehicle body panel. When disassembling, the clamping portion 111 of the tool is inserted into the gap between the fixing clamps, avoids the center of the fixing clamps, clamps the tail portions of the clamping jaws, and squeezes the handle 2 of the tool to close the clamping end 111 of the tool, so that the two clamping jaw support portions of the fixing clamp are retracted and separated from the vehicle body panel, and the fixing clamp can be quickly disassembled. Moreover, the bending head 11 of the front portion of the tool jaw 1 is bent as a whole along the axis direction of the hinge 3, which can avoid the interference between the tool and the vehicle body during disassembly. Using the tool to disassemble the head air curtain fixing clamp is convenient and fast, saves time, does not damage the fixing clamp, and saves cost.

[0032] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
