[0027] The following will describe the implementation methods of the present invention in detail with reference to specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0028] Example
[0029] like Figures 1 to 3 As shown, the compass with a pen-holding function includes a pin 1 and a lead foot 2, the pin 1 is rotatably connected to the top of the lead foot 2, the bottom of the pin 1 is provided with a pin 11, the bottom of the lead foot 2 is provided with a clamping assembly 3, a pencil 4 is inserted into the clamping assembly 3, the clamping assembly 3 includes a cylinder 31, a pressing block 32 and an elastic member 33, one side of the cylinder 31 is connected to the lead foot 2, the other side of the cylinder 31 is provided with an opening 34, one end of the pressing block 32 protrudes into the cylinder 31 from the side of the opening 34, the elastic member 33 is arranged between the protruding end of the pressing block 32 and the lead foot 2, a first slot 35 is provided on the cylinder 31 which passes through from top to bottom, and a second slot 36 is provided on the pressing block 32 which passes through from top to bottom, and the pencil 4 is arranged in the first slot 35 and the second slot 36.
[0030] By providing the clamping assembly 3 comprising a cylinder 31, a pressing block 32, and an elastic member 33, when installing or replacing a pencil 4, the user only needs to squeeze the end of the pressing block 32 that does not extend into the cylinder 31 to remove the pencil 4. The new pencil 4 is then placed into the first and second slots 35 and 36, and the pressing block 32 is released to complete the replacement. With only one step, the user can tighten and loosen the clamping assembly 3 to tighten or loosen the pencil 4 with one hand, making replacement simple and quick while also requiring fewer components.
[0031] In this embodiment, the elastic member 33 is a spring, which pushes the pressing block 32 away from the lead foot 2 to clamp the pencil 4. The side wall of the cylinder 31 is provided with two limiting rails 311, and the side wall of the pressing block 32 is provided with a limiting block 321 that cooperates with the limiting rails 311; the spring made of metal has a longer service life, and the elasticity of the spring will not decrease with the increase in the number of uses. The cooperation between the limiting rails 311 and the limiting blocks 321 makes it unnecessary for the two ends of the elastic member 33 to be fixedly connected to the pressing block 32 and the lead foot 2, and can also limit the position of the pressing block 32 in the cylinder 31 when it is not under force.
[0032] In other preferred embodiments, the elastic member 33 may also be in the form of an elastic sheet, such as a V-shaped, wavy shape, etc. The structure of the elastic sheet enables the elastic member 33 to be made of plastic material, which can reduce a certain cost.
[0033] In other preferred embodiments, one end of the elastic member 33 is fixedly connected to the pressing block 32 , and the other end of the elastic member 33 is connected to the lead foot 2 . This design eliminates the need for setting the limit rail 311 and the limit block 321 structure.
[0034] It also includes a U-shaped protective shell 5 with a closed top, and the bottom of the U-shaped protective shell 5 is rotatably connected to the pin 1; a storage groove 6 is provided on the pin 1 and the lead foot 2 at a position corresponding to the setting of the U-shaped protective shell 5; when the U-shaped protective shell 5 is used to store a compass, the U-shaped protective shell 5 is rotated downward to cover the pin 11, and the storage groove 6 provided on the pin 1 and the lead foot 2 is used to rotate the U-shaped protective shell 5 upward and hide it in the storage groove 6 when using the compass, so that there is no protrusion on the surface of the compass, thereby optimizing the feel of use.
[0035] In this embodiment, a side wall of the second slot 36 is provided with an anti-slip sheet 361 for preventing the pencil from slipping and causing scratches on the pencil surface.
[0036] In other preferred embodiments, the side wall of the second slot 36 is provided with a fixing pin (not shown in the figure), which can also prevent the pencil from slipping and has better anti-slip performance.
[0037] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
