[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 - 14 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problem that the instrument body and the external shell are mostly connected and fixed by bolts in the prior art, and the disassembly and maintenance operations of the instrument body are relatively cumbersome, this embodiment adopts the following technical scheme: a handheld application type radio wave speed meter, which is provided with a radio wave speed meter body 1, a shell 2, a hollow plate 3, a first spring 4, a mounting block 5 and a movable block 6, the radio wave speed meter body 1 is plugged and installed in the shell 2, and the upper right end of the radio wave speed meter body 1 is snap-connected with the mounting block 5 for limiting, the mounting block 5 drives the radio wave speed meter body 1 to form a disassembly structure in the shell 2, the upper right end of the shell 2 is fixedly connected with the hollow plate 3, and the first spring 4 is arranged inside the hollow plate 3, the movable end of the first spring 4 is fixedly connected with the mounting block 5, the mounting block 5 is arranged through the upper right end of the shell 2, and the mounting block 5 forms a telescopic structure in the hollow plate 3, the left and right sides of the upper end of the mounting block 5 are fixedly connected with the movable block 6, and the movable block 6 and the hollow plate 3 form an up and down sliding structure; like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, first, by pulling the movable block 6 upward, the movable block 6 slides between the hollow plate 3. At the same time, the movable block 6 drives the mounting block 5 to move upward. The mounting block 5 slides between the outer shell 2 and also slides in the hollow plate 3. The mounting block 5 squeezes the first spring 4, causing the mounting block 5 to undergo elastic deformation. Then, the radio wave speedometer body 1 is inserted and installed in the outer shell 2. When the left side of the radio wave speedometer body 1 is attached to the inner wall of the left end of the outer shell 2, the movable block 6 is directly released. At this time, the first spring 4 resumes its elastic deformation and pushes the mounting block 5 downward to engage with the upper right end of the radio wave speedometer body 1, so that the installation and positioning between the radio wave speedometer body 1 and the outer shell 2 can be very conveniently carried out; Embodiment 2: In order to solve the problems existing in the prior art that the detection head on the instrument is usually directly exposed outside, no protection mechanism is provided, it is easily damaged in the unused state, and it is also easy to accumulate dust, and it is inconvenient to wipe and clean the dust on the detection head. Therefore, in this embodiment, through the following technical solutions, a handheld application type radio wave speedometer is provided with a protection and cleaning mechanism 7, a connecting plate 11, a moving plate 12, a support block 13, a second spring 14 and a limiting plate 15. The protection and cleaning mechanism 7 is composed of a protective cover 8, a movable column 9 and a sponge 10. The protection and cleaning mechanism 7 is arranged on the left side of the outer shell 2. The sponge 10 is in close contact with the detection head on the left side of the radio wave speedometer body 1. The protective cover 8 is snap-connected to the left end of the outer shell 2, and a movable column 9 is rotatably connected to the middle of the protective cover 8. The right end of the movable column 9 is fixedly connected with the sponge 10. Connecting plates 11 are fixedly connected to the front and rear ends of the protective cover 8, and a moving plate 12 is inserted in the middle of the connecting plate 11. A support block 13 is slidably connected to the left side of the moving plate 12, and the support blocks 13 are respectively fixedly connected to the front and rear ends of the left side surface of the protective cover 8. A second spring 14 is arranged inside the moving plate 12, and the second spring 14 is located between the moving plate 12 and the protective cover 8; As Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown in the figure, a protective cover 8 is provided on the left side of the radio wave speedometer body 1. Through the setting of the protective cover 8, it can prevent the detection head from being directly exposed when not in use, and can well protect the detection head on the left side of the radio wave speedometer body 1. When in use, first rotate the movable column 9. The movable column 9 rotates in the middle of the protective cover 8, and the movable column 9 drives the sponge 10 to rotate. The movable column 9 is in a fitting setting with the detection head at the left end of the radio wave speedometer body 1. When the sponge 10 rotates, it can wipe and clean the detection head at the left end of the radio wave speedometer body 1. After cleaning, directly press the moving plate 12. The moving plate 12 moves in the connecting plate 11, and at the same time, the moving plate 12 slides with the support block 13. The moving plate 12 squeezes the second spring 14, causing the second spring 14 to undergo elastic deformation. The moving plate 12 disengages from the limiting plate 15, thereby releasing the limit between the protective cover 8 and the outer shell 2. Then, pull the protective cover 8 to the left, and the protective cover 8 disengages from the outer shell 2, so as to facilitate removing the protective cover 8 from the left end of the outer shell 2 and releasing the protection of the detection head.

[0020] Embodiment 3: In order to solve the problems existing in the prior art that most of the handles 16 and the instrument body are integrally formed or fixedly connected, which is not convenient to adjust the holding angle according to needs during use, and it is not convenient to fold and store the handle 16 after use, and the portability needs to be improved. Therefore, in this embodiment, through the following technical solutions, a handheld application type radio wave speedometer is provided with a handle 16, an anti-slip rubber sleeve 17 and an adjustment mechanism 18. The adjustment mechanism 18 includes a fixed block 19, a fixed groove 20, an adjustment block 21, a third spring 22, a fixed pin 23 and a connecting rod 24. The adjustment mechanism 18 is provided below the handle 16, and the adjustment mechanism 18 drives the handle 16 to form a flipping structure at the lower right end of the outer shell 2. The fixed block 19 is fixedly connected to the lower right end of the outer shell 2, and fixing grooves 20 for positioning are equiangularly opened on the outer side of the lower end of the fixed block 19. The lower end of the fixed block 19 is rotatably connected to the adjustment block 21, and the lower end of the adjustment block 21 is fixedly connected to the handle 16. A third spring 22 is arranged inside the adjustment block 21, and a fixed pin 23 is fixedly connected to the movable end of the third spring 22. The fixed pin 23 is telescopically connected in the adjustment block 21, and the upper end of the fixed pin 23 is inserted into the corresponding fixed groove 20. The right end of the fixed pin 23 is fixedly connected to the connecting rod 24, and the connecting rod 24 and the adjustment block 21 form an up-and-down sliding structure; As Figure 1 、 Figure 2 、 Figure 12 、 Figure 13 and Figure 14As shown, the handheld handle 16 is used for speed measurement through the radio wave speedometer body 1. At the same time, an anti-slip rubber sleeve 17 is arranged on the outer side of the handle 16, which can play a certain anti-slip role during the handheld use process. The radio wave speedometer body 1 is exactly the same as the existing radio wave speedometer, belonging to the existing mature technology, well-known to those skilled in the art, and will not be elaborated here. Moreover, according to needs, by pulling down the connecting rod 24, the connecting rod 24 drives the fixing pin 23 to move downward, and the fixing pin 23 squeezes the third spring 22, causing the third spring 22 to undergo elastic deformation. At this time, the fixing pin 23 moves out of the fixing groove 20, thereby releasing the limit between the adjusting block 21 and the fixing block 19. Then, the handle 16 is flipped, and the handle 16 drives the adjusting block 21 and the fixing block 19 to rotate, driving the handle 16 to be flipped and adjusted. The handle 16 can be flipped and adjusted to the state as shown in Figure 1 or Figure 13 shown. After the adjustment is completed, directly release the connecting rod 24. At this time, the third spring 22 restores its elastic deformation and pushes the fixing pin 23 to be inserted into the fixing groove 20 at the corresponding position, thereby facilitating the limitation between the adjusting block 21 and the fixing block 19. By flipping and adjusting the handle 16, the holding posture can be adjusted during use, making the detection more convenient; In addition, after use, the protective cover 8 is snapped onto the left end of the housing 2, combined with the engagement between the moving plate 12 and the limiting plate 15 to limit between the protective cover 8 and the housing 2, protecting the detection head on the left side of the radio wave speedometer body 1. Then, the handle 16 can also be flipped, and the handle 16 is flipped and adjusted to the state as shown in Figure 14 shown, so as to facilitate the folding and storage of the handle 16, increasing the overall portability and making it more convenient to carry.

[0021] The content not described in detail in this specification belongs to the existing technology well-known to those skilled in the art. The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings.
