[0025] The following further describes in detail the embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0026] Please refer to Figure 1 and Figure 2 , a fixture for the processing of a cover, including a bottom plate 1. On the upper left side of the bottom plate 1, a rectangular side plate 101 is fixedly installed. On the right side of the side plate 101, there is a base 103 fixedly connected to the bottom plate 1. The base 103 is used to limit the position of the protective cover 5, so that the positions of each fixed protective cover 5 are the same. On the right side of the base 103, there is a support frame 102 fixedly connected to the bottom plate 1. The support frame 102 applies a horizontal force to the protective cover 5, pushing the protective cover 5 towards the side plate 101, so that the V-shaped protective cover 5 on the upper end of the base 103 moves and is clamped with the base 103, achieving the effects of limiting and fixing. On the upper end of the base 103, a column 104 is fixedly installed. The upper end of the column 104 and the upper end of the side plate 101 are on the same horizontal plane. The column 104 is used to support the protective cover 5, so that the heights of the protective covers 5 are the same. The upper end of the column 104 and the upper end surface of the side plate 101 are on the same horizontal plane, so that the protective cover 5 is in a horizontal state after being fixed. At the same time, the side plate 101 and the column 104 support the left and right ends of the protective cover 5, preventing the phenomenon that the protective cover 5 is fixed obliquely, resulting in insufficient processing accuracy. The base 103 is an isosceles trapezoid, and the included angle between the two inclined surfaces of the base 103 is the same as the included angle of the V-shaped protective cover 5. When installing the protective cover 5, the first spring 203 of the first clamping assembly 2 is first compressed by the force of the protective cover 5, and then the first spring 203 rebounds and presses against the protective cover 5 for horizontal movement, so that the V-shaped opening of the protective cover 5 fits with the two inclined surfaces of the base 103 until a pressing effect appears, achieving the effects of positioning and fixing the protective cover 5 and ensuring that the positions of each protective cover 5 are the same.

[0027] Please refer to Figure 2 The upper end of the support frame 102 is rotatably connected to a fixing rod 105, and the support frame 102 is slidably connected to a first clamping assembly 2, and the first clamping assembly 2 is used to apply a lateral force to the protective cover 5 to ensure that the protective cover 5 is clamped to prevent the protective cover 5 from loosening during processing. One end of the fixing rod 105 is rotatably connected to the support frame 102, and the other end of the fixing rod 105 is slidably connected to a second clamping assembly 3. The upper end of the side plate 101 is provided with a third clamping assembly 4, and the second clamping assembly 3 and the third clamping assembly 4 are used to apply downward pressure to the protective cover 5 so that the protective cover 5 is tightly fitted with the upper ends of the side plates 101 and the columns 104. Furthermore, through the cooperation of the first clamping assembly 2, the second clamping assembly 3 and the third clamping assembly 4, the protective cover 5 is clamped and fixed to ensure that the fixed position of the protective cover 5 is consistent.

[0028] See also Figure 2 and Figure 3 The first clamping assembly 2 includes a slide bar 202 slidably connected to the support frame 102, the left end of the slide bar 202 passes through the support frame 102 and is rotatably connected to a clamping plate 201, a first spring 203 sleeved on the slide bar 202 is provided between the clamping plate 201 and the support frame 102, when the protective cover 5 is placed, the protective cover 5 is pressed down, one side of the protective cover 5 contacts with the clamping plate 201 and moves the clamping plate 201, so that the first spring 203 is compressed, when the upper end of the protective cover 5 is blocked by the side plate 101 and the column 104, the protective cover 5 does not move downward, the first spring 203 extends to make the clamping plate 201 abut against the protective cover 5, and push the protective cover 5 The protective cover 5 moves laterally, and the V-shaped protective cover 5 is fitted and pressed against the two inclined surfaces of the base 103, thereby realizing the horizontal fixation of the protective cover 5. The upper end of the splint 201 is provided with a folded edge bent toward the support frame 102, and the connection between the slide bar 202 and the splint 201 is located in the lower middle part of the splint 201. The upper end of the first clamping assembly 2 is provided with a folded edge, and when the protective cover 5 is pressed down, the protective cover 5 can move down more smoothly. At the same time, the connection between the slide bar 202 and the splint 201 is located in the lower middle part of the splint 201, and only a small downward force is needed to squeeze the first clamping assembly 2 to move, which is convenient for the protective cover 5 to move downward.

[0029] See also Figure 3 and Figure 4The second clamping assembly 3 includes a sliding column 302 slidably connected to the fixed rod 105. The lower end of the sliding column 302 passes through the fixed rod 105 and is ball-hinged with a clamping platform 301. The clamping platform 301 is truncated and larger at the top and smaller at the bottom. A second spring 303 is provided between the sliding column 302 and the fixed rod 105. One end of the second spring 303 is fixedly connected to the upper end of the sliding column 302, and the other end of the second spring 303 is fixedly connected to the fixed rod 105. After the protective cover 5 moves down and contacts the side plate 101 and the column 104, the fixed rod 105 is rotated. The fixing rod 105 rotates and drives the second clamping assembly 3 to move at the same time. When the second clamping assembly 3 contacts the protective cover 5, after the pressing platform 301 contacts the protective cover 5, since the outer wall of the pressing platform 301 is an inclined surface, the pressing platform 301 will be squeezed and moved upward, thereby driving the sliding column 302 to move upward. The upward movement of the sliding column 302 causes the second spring 303 to be stretched. When the pressing platform 301 reaches the upper end of the protective cover 5, the tension generated by the need for the second spring 303 to recover will cause the pressing platform 301 to continue to press on the protective cover 5, pressing the protective cover 5 down and fixing it to prevent the protective cover 5 from moving upward.

[0030] See also Figure 2 , Figure 5 and Figure 6 The third clamping assembly 4 includes a clamping frame 401, a groove 404 is provided at the lower end of the clamping frame 401, and the clamping frame 401 is slidably connected with a bolt 402 through the groove 404, and the bolt 402 is fixedly connected to the side plate 101. A third spring 403 sleeved on the bolt 402 is provided between the clamping frame 401 and the side plate 101, and the third spring 403 is in a compressed state. After the third spring 403 is compressed, it needs to be restored to generate elastic force. The third spring 403 moves downward against the clamping frame 401, so that the upper end of the clamping frame 401 presses the upper end of the protective cover 5 to ensure that the clamping frame 4 01 always has downward pressure to press down and fix the protective cover 5. The clamping frame 401 is C-shaped, and the groove 404 is L-shaped. The width of the groove 404 is consistent with the diameter of the bolt 402. When the third clamping assembly 4 contacts and presses down the protective cover 5, since the bolt 402 passes through the groove 404 and the width of the groove 404 is the same as the diameter of the bolt 402, it is only necessary to pull the upper end of the clamping frame 401 outward to make the groove 404 of the clamping frame 401 rotate around the bolt 402, and the clamping frame 401 can be separated from the protective cover 5, thereby releasing the downward pressure of the third clamping assembly 4 on the protective cover 5.

[0031] When the utility model is used:

[0032] First, the protective cover 5 is pressed down and installed on the device. When the protective cover 5 is pressed down, it will first contact with the first clamping assembly 2, and one side of the protective cover 5 will contact with the clamping plate 201 and move the clamping plate 201, so that the first spring 203 is compressed. When the upper end of the protective cover 5 is blocked by the side plate 101 and the column 104, the protective cover 5 will no longer move downward, and the first spring 203 will extend to make the clamping plate 201 and the protective cover 5 abut against each other, and push the protective cover 5 to move laterally. The two inclined surfaces of the V-shaped protective cover 5 and the base 103 are attached and pressed, so that the protective cover 5 is fixed laterally.

[0033] Then, the fixing rod 105 is rotated, and the fixing rod 105 rotates and drives the second clamping assembly 3 to move. When the second clamping assembly 3 contacts the protective cover 5, after the pressing platform 301 contacts the protective cover 5, since the outer wall of the pressing platform 301 is an inclined surface, the pressing platform 301 will be squeezed and moved upward, thereby driving the sliding column 302 to move upward. The upward movement of the sliding column 302 causes the second spring 303 to be stretched. When the pressing platform 301 reaches the upper end of the protective cover 5, the tension generated by the need for the second spring 303 to be restored causes the pressing platform 301 to keep pressing the protective cover 5, thereby fixing the protective cover 5.

[0034] Next, the compressed third spring 403 needs to be restored to generate elastic force, and the third spring 403 moves downward against the pressing frame 401, so that the upper end of the pressing frame 401 applies pressure to the upper end of the protective cover 5, pressing the protective cover 5 downward and fixing it;

[0035] Finally, after the processing of the protective cover 5 is completed, the protective cover 5 needs to be taken out, and the upper end of the clamping frame 401 is pushed outward to make the groove 404 of the clamping frame 401 rotate around the bolt 402, and the clamping frame 401 can be separated from the protective cover 5, and the downward pressure of the third clamping assembly 4 on the protective cover 5 is released. The fixing rod 105 is pushed to make the second clamping assembly 3 leave the upper end of the protective cover 5 to release the downward pressure of the second clamping assembly 3 on the protective cover 5. After completion, the protective cover 5 can be directly pulled out.
