[0007] Further, a base groove is opened on the inner wall of the top of the lower cover, there are multiple groups of base grooves, and the multiple groups of base grooves are symmetrically arranged on the left and right sides of the lower cover. A base is fixedly installed on the inner wall of the base groove, and the base is used in cooperation with the clamping assembly. The clamping assembly includes a convex shell, the outer wall of the convex shell is fixedly connected with the inner wall of the hole, and a first groove is opened on the inner wall of the top of the convex shell.
[0008] Further, a metal ball groove is opened at the bottom of the convex shell, there are multiple groups of metal ball grooves, and the multiple groups of metal ball grooves are symmetrically arranged.
[0009] Further, a cylindrical rod is arranged on the inner wall of the first groove, and the cylindrical rod is movably connected with the first groove
[0010] Furthermore, a spring is provided on the outer wall of the columnar rod, the spring is sleeved with the columnar rod, and the bottom of the spring is movably connected with the groove.
[0011] Furthermore, a conical seat is fixedly installed at the bottom of the columnar rod, and a baffle is fixedly installed on the outer wall of one side of the conical seat. The baffles are provided in multiple groups, and the multiple groups of baffles are symmetrically arranged.
[0012] Furthermore, metal balls are arranged on the inner wall of the metal ball groove, and the metal balls are arranged in multiple groups, and the metal balls are movably connected with the metal ball groove.

[0018] When the plastic strip contacts the metal strip, the cylindrical rod in the clamping assembly makes the bottom of the convex shell contact with the base, and the cylindrical rod is pressed to make the metal ball roll between the two baffles and contact the metal ball groove, wherein the inner wall radius of the metal ball groove is larger than the outer wall radius, causing the protruding part of the metal ball in the metal ball groove to contact the circular groove 127, generating friction to clamp the metal ball, thereby fixing the upper cover and the lower cover, and pressing the cylindrical rod again to make the metal ball roll to the top of the conical seat, thereby making the metal ball detach from the metal ball groove, achieving the effect of separating the upper cover and the lower cover, wherein the release of the tension of the spring will reset the cylindrical rod.
[0019] The solution used in this patent is that when the upper cover and the lower cover are combined, the original surface contact is changed into line-surface contact. This structure can reduce the scratches when disassembling the upper and lower covers of the hardware structure, thereby increasing the service life of the product and maintaining a beautiful appearance.

[0035] A base groove 121 is opened on the inner wall of the top of the lower cover 120. There are multiple groups of the base grooves 121, and the multiple groups of base grooves 121 are symmetrically arranged on the left and right sides of the lower cover 120. A base 125 is fixedly installed on the inner wall of the base groove 121. The base 125 is used in cooperation with the clamping assembly 140.
[0036] Please refer to Figure 5 Figure 7 , the clamping assembly 140 includes a convex shell 141. The outer wall of the convex shell 141 is fixedly connected to the inner wall of the hole 114. A first groove 144 is opened on the inner wall of the top of the convex shell 141;
[0037] A metal ball groove 143 is opened at the bottom of the convex shell 141. There are multiple groups of the metal ball grooves 143, and the multiple groups of metal ball grooves 143 are symmetrically arranged. Metal balls 146 are provided on the inner wall of the metal ball groove 143. There are multiple groups of the metal balls 146, and the metal balls 146 are movably connected to the metal ball grooves 143. A cylindrical rod 142 is provided on the inner wall of the first groove 144. The cylindrical rod 142 is movably connected to the first groove 144.

[0038] Please refer to Figure 2 Figure 9 , a second groove 126 is provided on the inner wall of the base 125, a circular groove 127 is provided at the bottom of the inner wall of the second groove 126, the circular groove 127 is used in cooperation with the clamping assembly 140, a keycap groove 112 is provided on the inner top wall of the upper cover 110, and the keycap 130 is vertically inserted into the top of the inner wall of the lower cover 120 perpendicular to the keycap groove 112.
[0039] Through the above technical solution, in the present utility model, by increasing the slope of the lower cover 120, scratching between the upper cover 110 and the lower cover 120 is avoided when disassembling and assembling the structural hardware. Rectangular strips 111 are fixedly installed on the four sides of the bottom of the upper cover 110, and plastic strips 113 are fixedly installed at the bottoms of the rectangular strips 111. Inclined bodies 122 are fixedly installed around the surface of the lower cover 120. The inclined bodies 122 are right-angled triangular bodies. An inclined groove 124 is provided on the inner wall of one side of the inclined surface of the inclined body 122, and a metal strip 123 is fixedly installed on the inner wall of the inclined groove 124. The metal strip 123 is also a right-angled triangular body. When the upper cover 110 and the lower cover 120 are fixedly installed and in normal use, the plastic strip 113 contacts the inclined surface of the metal strip 123, so that the contact between the upper cover 110 and the lower cover 120 is changed from the original surface contact to line contact, avoiding the problem of easy scratching during disassembly and assembly.
[0040] When the plastic strip 113 contacts the metal strip 123, the cylindrical rod 142 in the clamping assembly 140 makes the bottom of the convex shell 141 contact the base 125. Press the cylindrical rod 142 to make the metal ball 146 roll between the two baffles 148 and contact the metal ball groove 143. The inner wall radius of the metal ball groove 143 is greater than the outer wall radius, resulting in the part of the metal ball 146 protruding from the metal ball groove 143 contacting the circular groove 127, generating frictional force to lock the metal ball 146, thereby fixing the upper cover 110 and the lower cover 120. Press the cylindrical rod 142 again to make the metal ball 146 roll to the top of the conical seat 147, so that the metal ball 146 disengages from the metal ball groove 143, achieving the separation effect of the upper cover 110 and the lower cover 120. The spring 145 releases tension to reset the cylindrical rod 142.
[0041] Embodiment 2, please refer to Figure 8 Figure 9 , an arc-shaped strip 115 is fixedly installed at the bottom of the upper cover 110, and an arc-shaped insert 128 is fixedly installed on the top surface of the lower cover 120. By moving the upper cover 110 or the lower cover 120, the arc-shaped insert 128 is inserted into the arc-shaped strip 115, thereby fixing the upper cover 110 and the lower cover 120 to achieve the purpose of normal use.
[0042] Through the above technical solution, an arc-shaped strip 115 is fixedly installed at the bottom of the upper cover 110 of the present utility model, and an arc-shaped insertion strip 128 is fixedly installed on the top surface of the lower cover 120. The arc-shaped insertion strip 128 is perpendicular to the arc-shaped strip 115. The arc-shaped insertion strip 128 and the arc-shaped strip 115 are made of elastic plastic. When the upper cover 110 or the lower cover 120 is moved to make the plastic strip 113 fit with the metal strip 123, slightly exerting force will cause the arc-shaped insertion strip 128 to be inserted into the arc-shaped strip 115, so that the upper cover 110 and the lower cover 120 are fixed, achieving the normal use effect.
