The movement of the cross bar 401 can be controlled by the push rod 407. By pushing the sliding column 408, the limit block 406 is driven to compress the spring inward, and the limit teeth on the side of the limit block 406 are separated and meshed with the limit teeth on the inner side of the box body. The limit block 406 loses its restriction, and the sliding cross bar 401 can move forward and backward.

[0025] like Figure 8 As shown, four protection mechanisms 6 are provided on the side of the sliding cross bar 401 for safely protecting the end of the tool 104. The protection mechanism 6 includes a positioning ring 601, which is fixedly connected to the sliding cross bar 401. A protection pad 602 is fixedly connected inside the positioning ring 601. The protection pad 602 is a soft rubber product that can reduce the force on the end of the tool 104.

[0026] like Figure 1 , Figure 2As shown, two sliding grooves are opened on the side of the box body 101, and the push rod 407 is slidably connected in the sliding groove opened on the side of the box body 101. Limiting teeth are provided on both sides of the inner side of the sliding groove opened on the side of the box body 101. The limiting teeth on the side of the box body 101 are engaged with the limiting teeth on the end side of the limiting block 2 406. A handle 103 is fixedly connected to the right end of the box body 101, and a tool 104 is provided on the upper side of the clamping mechanism 2.

[0027] like Figure 1 As shown, the inner side of the box body 101 is rotatably connected to the cover body 102 via a rotating shaft, the front end of the cover body 102 is provided with two notches, and the middle part of the front end of the cover body 102 is provided with a rectangular sliding groove.

[0028] like Figure 1 , Fig. 9 As shown, a clamping mechanism 5 is provided at the front end of the cover body 102, and the clamping mechanism 5 can clamp the cover body 102. The clamping mechanism 5 includes a fixed sleeve 501, and the fixed sleeve 501 is fixedly connected in a sliding groove opened in the middle part of the front end of the cover body 102. A spring four 502 is fixedly connected to one end of the fixed sleeve 501, and a sliding block 503 is fixedly connected to the other end of the spring four 502. A through hole is opened in the fixed sleeve 501, and a pull column 504 is slidably connected in the through hole opened in the fixed sleeve 501, and the other end of the pull column 504 is fixedly connected to the sliding block 503.

[0029] Working principle: When the tool 104 is stored in the invention, the pull column 504 is pulled outward, and the pull column 504 compresses the spring four 502 through the sliding block 503. The sliding block 503 loses the limit on the slide groove of the box body 101, and pushes the cover body 102 upward so that the cover body 102 opens upward, and the tool 104 is placed on the upper end of the pressing block 201 and pressed downward. The tool 104 drives the vertical sliding rod 202 to move downward through the pressing block 201, and the vertical sliding rod 202 drives the swing rod 206 to move downward through the rotating shafts on both sides. The downward movement of the swing rod 206 drives the horizontal columns 208 on both sides to rotate relative to each other. The horizontal columns 208 on both sides drive the fixed frame 210 to rotate relative to each other through the pillars 209. The fixed frame 210 drives the arc plate 211 to clamp the tool 104, and the vertical sliding rod 202 compresses the spring one 204 downward through the fixed plate 203.

[0030] When the vertical sliding rod 202 slides downward, the teeth on its side push the limit block 301 to move left and right. The limit block 301 moves upward by limiting the vertical sliding rod 202 through the teeth. After the tool 104 is fully placed in the clamping mechanism 2, the sliding column 408 is pressed inward and the push rod 407 is pulled to the middle. The push rod 407 drives the sliding cross bar 401 to move toward the middle. The sliding cross bar 401 drives the protection mechanism 6 to move toward the middle. The sliding cross bar 401 drives the rotating shaft to move The roller 402 moves toward the middle, and the sliding cross bars 401 on both sides drive the limit block 2 406 to move toward the middle. When the protection mechanism 6 contacts the tool 104, the sliding column 408 is released. At this time, the spring three 405 releases the elastic force to push the limit block 2 406 outward. The box body 101 limits the left and right movement of the sliding cross bar 401 through the cooperation of the limit teeth and the side teeth of the limit block 2 406, so that the two ends of the tool 104 are against the protection pad 602, and the protection mechanism 6 clamps the tool 104.

[0031] When the cover 102 is closed downward, the sliding block 503 moves outward through the inclined surface and squeezes the spring four 502. When the sliding block 503 is located in the sliding groove opened in the box body 101, the spring four 502 releases its elastic potential energy to push the sliding block 503 into the sliding groove opened in the box body 101, and the cover 102 seals the box body 101 through the sliding block 503.

[0032] When the cutter 104 is taken out, the pull column 503 is pulled outward, and the pull column 503 compresses the spring 502 through the sliding block 503, so that the sliding block 503 loses the limit of the slide groove of the box body 101 and pushes the cover body 102 upward, so that the cover body 102 opens upward.

[0033] The sliding column 408 is pushed inward, and the right sliding column 408 drives the limit block 2 406 to compress the spring 3 405 inward. The side limit teeth of the right box body 101 lose the limit on the limit block 2 406, and the push rod 407 is pushed outward. The push rod 407 drives the right sliding cross bar 401 to move outward through the roller 402, and the right sliding cross bar 401 drives the protection pad 602 to move outward through the positioning ring 601, and pushes the left height adjustment mechanism 4 in turn, so that the left sliding cross bar 401 drives the protection pad 602 to move outward through the positioning ring 601, so that the protection mechanism 6 releases the limit on the tool 104, and then, the pull rod 309 is continuously pulled to the right, the pull rod 309 rotates through the rotating shaft, and the lower end of the pull rod 309 drives the horizontal sliding rod 307 to move to the left through the rotating shaft, and the horizontal sliding The movable rod 307 pushes the limit plate 304 outward through the inclined surface of the wedge block 306. The limit plate 304 drives the limit block 1 301 to move outward through the sliding rod 303 and compresses the spring 2 302. The limit block 1 301 loses the limit on the vertical sliding rod 202 through the teeth. Further, the spring 1 204 releases its elastic potential energy and pushes the vertical sliding rod 202 upward through the fixed plate 203. The vertical sliding rod 202 drives the rocker rods 206 on both sides to move upward through the rotating shaft. The rocker rod 206 drives the cross column 208 to rotate outward. The cross column 208 drives the fixed frame 210 to open outward through the support 209. The fixed frame 210 drives the arc plate 211 to lose the limit on the tool 104. At the same time, the vertical sliding rod 202 pushes the tool 104 upward through the pressing block 201, so that the tool 104 can be taken out.

[0034] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
