[0031] See also Figure 1-5 The utility model provides a technical solution: a calculator, comprising a calculator body 1 and a folding plate 2, the surface of the calculator body 1 is provided with an anti-slip device 3, and the surface of the calculator body 1 is provided with a protective device 4.

[0032] The specific arrangement and function of the anti-skid device 3 and the protective device 4 will be described in detail below.

[0033] like Figure 2 and Figure 3 as well as Figure 5 As shown, the anti-skid device 3 includes two anti-skid strips 31, which are placed on the lower surface of the calculator body 1. The lower surface of the calculator body 1 is fixedly connected with a plurality of sharp protrusions 32, and the surface of the sharp protrusions 32 is fixedly connected with barbs 33. First, the anti-skid strips 31 are placed on the bottom of the calculator. At this time, the anti-skid strips 31 are in contact with the sharp protrusions 32, so that the anti-skid strips 31 are initially fixed. The setting of the barbs 33 can effectively improve the stability of the anti-skid strips 31 and reduce the shaking of the anti-skid strips 31. The side wall of the calculator body 1 is fixedly connected with a support plate 34, and the surface of the support plate 34 is slidably connected with a push plate 35, and the surface of the push plate 35 is fixedly connected with spikes 36. At this time, the push plate 35 on the support plate 34 is pushed, and the push plate 35 drives the spikes 36 to be inserted into the anti-skid strip 31, further improving the stability of the anti-skid strip 31. The inner wall of the push plate 35 is fixedly connected with a spring 37, and one end of the spring 37 is fixedly connected to the support plate 34. The push plate 35 will drive the spike 36 to stably insert into the anti-slip strip 31 under the action of the tension of the spring 37, thereby improving the stability of the push plate 35. The inner wall of the anti-slip strip 31 is fixedly connected with a first magnet 38, and the surface of the anti-slip strip 31 is provided with a slot, and the slot on the surface of the anti-slip strip 31 is placed with a second magnet 39, and the first magnet 38 and the second magnet 39 are fixedly connected with a connecting rope on the side close to each other. The second magnet 39 can be taken out and placed inside the table. At this time, under the attraction of magnetic force, the first magnet 38 and the second magnet 39 will attract each other and be connected and fixed, thereby improving the stability of the calculator.

[0034] like Figure 1 and Figure 4As shown, the protective device 4 includes two fixed plates 41, the fixed plates 41 are fixedly connected to the calculator body 1, the surface of the fixed plate 41 is rotatably connected to a round rod 42, one end of the round rod 42 is fixedly connected to a turning handle 43, and the arc surface of the round rod 42 is fixedly connected to a protective cloth 44. Pull the protective cloth 44 to the other end of the calculator, and the protective cloth 44 can protect the calculator, reducing the problem of direct contact and collision between the calculator and other objects, which may cause damage. There are two latches 46 sliding through the surface of the protective cloth 44, and the surface of the calculator body 1 is provided with two slots, and the latches 46 are engaged with the slots on the surface of the calculator body 1. Push the latch 46 to insert into the calculator body 1, thereby improving the stability of the protective cloth 44. The surface of the turning handle 43 is slidably connected to an insertion rod 45, and the surface of the fixed plate 41 is provided with a plurality of round holes, and the insertion rod 45 is engaged with the round holes on the surface of the fixed plate 41. At this time, the insertion rod 45 is pushed into the fixing plate 41 , thereby improving the tightness of the protective cloth 44 , reducing the shaking and contraction of the protective cloth 44 due to force, and further improving the protective effect of the protective cloth 44 .

[0035] Working principle: when the calculator is in use, first place the anti-slip strip 31 at the bottom of the calculator. At this time, the anti-slip strip 31 contacts the spike 32, thereby performing preliminary fixing of the anti-slip strip 31. The setting of the barb 33 can effectively improve the stability of the anti-slip strip 31 and reduce the shaking of the anti-slip strip 31. At this time, the push plate 35 on the support plate 34 is pushed, and the push plate 35 drives the spike 36 to insert into the anti-slip strip 31, further improving the stability of the anti-slip strip 31. The push plate 35 will drive the spike 36 to stably insert into the anti-slip strip 31 under the action of the tension of the spring 37, thereby improving the stability of the push plate 35. At the same time, the second magnet 39 can be taken out and placed inside the table. At this time, under the attraction of magnetic force, the first magnet 38 will attract the second magnet 39 to connect and fix, thereby improving the stability of the calculator. By setting the anti-slip device 3, the stability of the calculator is improved, the problem of sliding and falling when the calculator is working is reduced, the fixing and replacement of the anti-slip strip 31 is convenient, and the working efficiency of the calculator is improved as much as possible.

[0036] When a calculator is carried, it is mostly placed in a backpack and is easily in contact with other items in the backpack. At this time, the protective cloth 44 is pulled to the other end of the calculator, and the latch 46 is pushed to be inserted into the calculator body 1, thereby improving the stability of the protective cloth 44. At this time, the insertion rod 45 is pushed to be inserted into the fixed plate 41, thereby improving the tightness of the protective cloth 44 and reducing the shaking and shrinkage of the protective cloth 44 under force, thereby improving the protective effect of the protective cloth 44. At this time, the protective cloth 44 can protect the calculator and reduce the problem of damage to the calculator when it collides with other items. By setting the protective device 4, the protective effect of the calculator is improved, the problem of damage to the calculator is reduced, and the practicality of the calculator is improved as much as possible.
