[0016] Figure 2 It is a schematic diagram of the structure of the metal shrapnel. DETAILED DESCRIPTION

[0017] like Figure 1-2 As shown, the quick-detachable lower frame structure of the utility model comprises a metal spring sheet 3 connecting the lower frame 1 and the rubber frame 2, and the metal spring sheet 3 is formed by stamping of stainless steel or spring steel.

[0018] The metal spring 3 is in a V-shaped structure as a whole. A lower clamping portion 32 is provided at the lower part of the two arm plates 31 of the metal spring 3. An upper clamping portion 33 is provided at the top of the two arm plates 31 of the metal spring 3. The cross section of the lower clamping portion 32 is semicircular, and the cross section of the upper clamping portion 33 is circular. A lower clamping seat 21 is provided on the plastic frame 2. A lower positioning groove 22 is provided on the lower clamping seat 21. Lower clamping grooves matching the shape of the lower clamping portion 32 are provided on both sides of the lower positioning groove 22. An upper clamping seat 11 is provided on the lower frame 1 at a position corresponding to the lower clamping seat 21. An upper positioning groove 12 is provided on the upper clamping seat 11. Upper clamping grooves matching the shape of the upper clamping portion 33 are provided on both sides of the upper positioning groove 12. The metal spring 3 is connected to the upper positioning groove 12 of the upper clamping seat 11 and the lower positioning groove 22 of the lower clamping seat 21, and the lower clamping part 32 and the upper clamping part 33 on the two arm plates 31 of the metal spring 3 are respectively clamped in the corresponding lower clamping groove and upper clamping groove. The two arm plates 31 of the metal spring 3 rebound under the elastic action to squeeze the lower clamping seat 21 and the upper clamping seat 11, thereby realizing a reliable connection between the lower frame 1 and the rubber frame 2.

[0019] A plug-in guide structure is provided between the lower frame 1 and the plastic frame 2, and the plug-in guide structure includes an insert tongue 13 provided on the lower frame 1 and a guide seat 23 provided on the plastic frame 2, and the insert tongue 13 is slidably matched with a guide hole of the guide seat 23. When the lower frame 1 is assembled downwardly onto the plastic frame 2, the relative positions of the two during and after the assembly process can be ensured by the limiting effect of the plug-in guide structure.

[0020] Preferably, a trumpet-shaped guide opening is provided at the bottom entrance end of the upper positioning groove 12 , and the guide opening is designed to facilitate the introduction of the metal spring 3 into the upper holder 11 of the lower frame 1 .

[0021] The assembly process of the utility model:

[0022] 1. Install the metal spring 3 into the lower positioning groove 22 of the lower clamping seat from the front end surface of the lower clamping seat 21, wherein the lower clamping portion 32 is clamped into the corresponding lower clamping groove;

[0023] 2. Assemble the lower frame 1 from top to bottom to press the metal spring 3 into the upper positioning groove 12 of the upper clamping seat 11, wherein the upper clamping portion 33 is clamped into the corresponding upper clamping groove.

[0024] The disassembly process of the utility model is as follows: a pin sheet or other tool is inserted into the guide opening of the upper positioning groove 12, and then the opening of the metal spring sheet 3 is pressed from both sides to the middle to make it smaller, the upper clamping portion 33 is separated from the upper clamping groove, and then the upper frame is taken out from the top.
