[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0031] See also Figures 1 to 4 The utility model is a calculation instrument for engineering cost, comprising a cover plate 1 and a storage groove 101 arranged at the rear end of the upper surface thereof, a cleaning cotton 102 is bonded to the inner bottom end of the storage groove 101, and a protection component 2 is arranged at the corners of the outer wall of the cover plate 1; the protection component 2 comprises a cushion 201 and a rubber column 202 arranged at the inner center position thereof, and a spring 203 is sleeved on the outer side of the outer wall of the rubber column 202;

[0032] Specifically, slide grooves 1011 are arranged on the upper sides of the inner walls of the storage groove 101, and limiting grooves 1012 are evenly spaced from front to back on the upper surfaces of the storage groove 101 and the cleaning cotton 102. Anti-slip pads 103 are arranged at the four corners of the lower surface of the cover 1. A calculator body 104 is installed inside the storage groove 101, and connecting rods 1041 are movably connected to the center positions of the outer walls of both sides of the calculator body 104. The other end of the connecting rod 1041 is movably connected to a slider 105, and the inner side of the slider 105 is located inside the slide groove 1011. A bracket 106 is movably connected to the center position of the rear end face of the calculator body 104.

[0033] Furthermore, the cleaning cotton 102 can be used to clean the surface of the calculator body 104 without manual cleaning, thereby reducing the workload of the staff. The elastic properties of the rubber column 202 and the spring 203 can play a role in buffering and shock absorption when it falls, thereby protecting the calculator body 104. The anti-slip pad 103 can play a role in preventing slipping when using the calculator body 104. The structures such as the connecting rod 1041, the slider 105, and the bracket 106 are all existing technologies, so they will not be described in detail here.

[0034] The operation process of this embodiment is as follows: when the calculator body 104 is in use, the calculator body 104 is easily flipped onto the surface of the cover plate 1 through the slide groove 1011, the connecting rod 1041 and the slider 105, and the calculator body 104 is tilted and supported to a suitable angle by the bracket 106 and the limiting groove 1012. When the calculator body 104 is not in use, the above operation is repeated, the calculator body 104 is buckled inside the storage groove 101, and the slider 105 and the slide groove 1011 are used to slide the calculator body 104 back and forth. The surface of the calculator body 104 can be cleaned by the cleaning cotton 102 located inside the storage groove 101, thereby achieving the purpose of cleaning, reducing the labor intensity of the staff, and being efficient. When the calculator falls accidentally, the soft pad 201 on the outer side of the outer wall around the cover plate 1 falls to the ground, and is forced to squeeze the rubber column 202 and the spring 203 located on the inner side. Under the elastic performance of the rubber column 202 and the spring 203, a certain impact force can be absorbed, thereby playing a buffering and protective role for the calculator to prevent the calculator from falling and being damaged. Specific embodiment 2

[0035] See also Figure 1 , 5 On the basis of the first specific embodiment, a portable component 3 is arranged at the center position of the front end surface of the cover plate 1, and the portable component 3 includes a fixed shell 301 and a fixed rod 302 fixed to one side of the front end thereof, a right rotating shaft 303 is rotatably installed on one side of the fixed rod 302, and a rear rotating shaft 304 is rotatably installed at the rear end between the fixed rod 302 and the right rotating shaft 303.

[0036] Specifically, a right sprocket 3031 is sleeved on the bottom of the outer wall of the right rotating shaft 303, and a rear sprocket 3041 is sleeved on the bottom of the outer wall of the rear rotating shaft 304. The right sprocket 3031 and the outer walls of the rear sprocket 3041 are meshingly connected. A winding roller 306 is sleeved on the top of the outer wall of the right rotating shaft 303, and a portable rope 305 is sleeved on the outer side of the outer wall of the winding roller 306. The other end of the portable rope 305 is fixed on the outer wall of the fixed rod 302. A coil spring 307 is sleeved at the center position of the outer wall of the right rotating shaft 303, and the other end of the coil spring 307 is fixed on the outer wall of the rear rotating shaft 304.

[0037] Furthermore, the fixed rod 302 is fixed inside the fixed shell 301, and the right rotating shaft 303 and the rear rotating shaft 304 can both rotate inside the fixed shell 301. The gear on the outer wall of the right toothed disc 3031 is meshed and connected with the gear on the outer wall of the rear toothed disc 3041, which plays a transmission role. Under the elastic performance of the winding spring 307, the portable rope 305 can be automatically reeled on the outer wall of the winding roller 306.

[0038] The operation process of this embodiment is as follows: if the computing device needs to be carried, the portable rope 305 is pulled outward, and the portable rope 305 is forced to move outward, and the portable rope 305 wound on the outer wall of the winding roller 306 is pulled out, and the winding roller 306 inside it is driven to rotate, and the right shaft 303 inside it is driven to rotate through the winding roller 306, wherein the right gear disc 3031 is sleeved on the outer wall of the right shaft 303, so the rotation of the right shaft 303 will drive the right gear disc 3031 on its outer wall to rotate, and the outer wall of the right gear disc 3031 is meshed with the gear on the outer wall of the rear gear disc 3041, therefore, when the right gear disc 3031 rotates, it will drive the rear gear disc 3041 to rotate, and through the rear gear disc 304 1 drives the rear shaft 304 on its inner wall to rotate, and at the same time pulls the coil spring 307 wound on the outer wall of the right shaft 303 to the outer wall of the rear shaft 304. At this time, the portable rope 305 will extend, and then the staff can use the portable rope 305 to carry the computing instrument. When it is not needed to carry, stop applying force to the portable rope 305. At this time, the coil spring 307 is recovered to the outer wall of the right shaft 303 under the elastic performance of the coil spring 307, and the rear shaft 304 and the right shaft 303 are rotated through the right gear plate 3031 and the rear gear plate 3041, so that the winding roller 306 can be driven to rotate, and the extended portable rope 305 is rewound on the outer wall of the winding roller 306, so as to facilitate the staff to carry and use the computing instrument.
