[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1 to 4 As shown, this application provides a flexible tip test pen, including: a contact end post 2, which is disposed at one end of the test pen insulating shell 1, and a contact tip 201 is fixedly disposed at one end of the contact end post 2. Four smoothing grooves 2011 and a locking slot 2012 are formed on the outer side of the contact end post 2, the smoothing grooves 2011 and the locking slots 2012 are in a connected state; and a release assembly 3, which is disposed between the contact end post 2 and the test pen insulating shell 1, and is used to release or hold the contact tip 201. The head post 2 and the release assembly 3 include a sliding plate 302. Four pressure arms 303 are rotatably arranged on the outer side of the sliding plate 302. A sliding block 305 is rotatably arranged at the other end of the pressure arms 303. A fixed slide frame 306 is slidably arranged on the outer side of the sliding block 305. A release clamping plate 308 is fixedly arranged on the other side of the sliding block 305. A clamping block 3081 for engaging in the block lock groove 2012 is provided at the end of the release clamping plate 308. One side of the clamping block 3081 is inclined.

[0027] After adopting the above technical solution, the contact end post 2 is slid into the release clamping plate 308, and the clamping block 3081 will slide along the smooth groove 2011. At this time, the first spring 301 and the second spring 304 are in the extended state. When the clamping block 3081 slides into the block insertion locking groove 2012, due to the rebound force of the first spring 301 and the second spring 304, the sliding plate 302 and the sliding block 305 return to their original positions, thereby achieving the locking effect on the contact end post 2. When disassembling the contact end post 2, the release clamping plate 308 can be separated by moving the sliding plate 302 close to the contact fixing plate 309, so that the clamping block 3081 can leave the block insertion locking groove 2012. Then the contact end post 2 can be taken out, and different shapes of contact tips 201 can be replaced, such as curved or extended ones. However, the contact end post 2 at one end of each different shape of contact tip 201 is the same, which is convenient for installation and disassembly, making the test pen more flexible and the detection simpler.

[0028] The sliding plate 302, the pressure arm 303, the sliding block 305, the fixed sliding frame 306, and the release clamp 308 are made of insulating PVC material.

[0029] This prevents the electricity introduced into the contact end post 2 and contact tip 201 from being transmitted to the release assembly 3, thus preventing interference with the electrical measurement results.

[0030] For example, a first spring 301 is fixedly provided at one end of the sliding plate 302, and a connecting plate 309 is fixedly provided at the other end of the first spring 301. The connecting plate 309 is fixedly provided on one side of the fixed slide frame 306, and a block groove 307 for sliding block 305 is provided on one side of the fixed slide frame 306.

[0031] In an optional implementation, when releasing the contact end post 2, the sliding plate 302 needs to move closer to the contact fixing plate 309. Therefore, the first spring 301 is in a gradually compressed state, so that the contact end post 2 can be released. After releasing the contact end post 2, the sliding plate 302 can automatically return to its original position.

[0032] It should be noted that a second spring 304 is fixedly installed on one side of the sliding block 305, and a support plate is fixedly installed on the other end of the second spring 304. The support plate is fixedly installed on one side of the fixed slide frame 306.

[0033] In an optional embodiment, when the release clamp 308 releases the contact end post 2, the movement of the sliding block 305 will cause the second spring 304 to extend, so that after the release is completed, the sliding block 305 and the release clamp 308 can automatically return to their original positions, which is convenient for the next installation of the contact end post 2.

[0034] It should be noted that a component protective shell 101 is fixedly installed at the end of the insulating shell 1 of the test pen. The component protective shell 101 is located on the outside of the release component 3. A sliding plate 310 is fixedly installed on the outside of the sliding plate 302. An movable sliding groove for sliding the sliding plate 310 is opened on the outside of the component protective shell 101. A fixed sliding frame 306 is fixedly installed on the inside of the component protective shell 101. The component protective shell 101 is made of insulating transparent PVC material.

[0035] In this embodiment, when it is necessary to release the contact end post 2, the pry plate 310 can be pried to one side, so that the pry plate 310 can slide along its trajectory inside the movable slide groove. When releasing the contact end post 2, the pry plate 310 moves closer to the contact end post 2, so that the release assembly 3 can achieve the effect of releasing the contact end post 2. The protective shell 101 of the assembly is made of insulating transparent PVC material, so that the internal structure of the release assembly 3 can be seen, and it is not conductive and will not affect the measurement results.

[0036] For example, the other end of the insulating shell 1 of the test pen is threaded with a metal pen cap 102. One end of the metal pen cap 102 is provided with a conductive spring 103. One end of the conductive spring 103 is provided with a neon tube 104. The other end of the neon tube 104 is provided with a resistor 105. The resistor 105 passes through and is slidably disposed on one end of the sliding contact plate 302. The resistor 105 passes through and is fixedly disposed on one end of the contact plate 309. The resistor 105 is in contact with one end of the contact post 2.

[0037] The electricity introduced through the contact tip 201 and contact end post 2 passes through the resistor 105, which then causes the neon tube 104 to light up. The electricity forms a circuit with the conductive spring 103 and the metal pen cap 102. When measuring electricity, the finger needs to press the metal pen cap 102.
