[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.
[0016] like Figures 1-2 As shown in the figure, the composite probe with illumination function described in this specific embodiment includes a composite probe body 1, which includes a pen body 3. A probe is installed inside the pen body 3, and the front end of the probe extends out of the front end of the pen body 3 to form a probe head 5. A battery box 2 is provided in the middle of the pen body 3. A hidden probe head protective sleeve 6 for protecting the probe head is installed in the frustoconical part at the front of the battery box 2. A movable illumination component 4 for illumination with adjustable illumination height is installed on the front of the battery box 2, thus forming a composite probe.
[0017] The movable lighting assembly 4 in this design includes a lighting compartment 49 located at the front of the battery box 2. The lighting compartment 49 has several equidistant front slots at its center. A vertical plate 44 is located at the rear of the lighting compartment 49, with a rear slot corresponding to the front slots in its center. A vertical strip groove for wiring is located on the left side of the vertical plate 44. A square hole is located on the top surface of the lighting compartment 49, and a square vertical rod 43 is installed within the square hole. A central adjustment rod is located on the square vertical rod 43, penetrating its body. The square vertical rod 43 has a top cap 42 at its top end. A pin 41 is provided on the front groove and the corresponding rear groove. The pin 41 passes through the middle adjusting groove of the square vertical rod 43 to fix the vertical position of the square vertical rod 43 within the lighting chamber 49. The bottom end of the square vertical rod 43 is connected to the right side of the top surface of the horizontal sleeve 46. A wire hole head 47 is provided at the rear end of the horizontal sleeve 46 and is located in the vertical strip groove. A lighting lamp head 45 is provided at the front end of the horizontal sleeve 46.
[0018] In this design, a circuit board 22 for controlling the lighting head is installed in the control compartment at the lower rear of the battery box 2, and a battery 21 is installed in the upper rear battery compartment of the battery compartment 23 above the control compartment. The circuit board 22 is electrically connected to the battery compartment 23 and to the lamp beads 45 in the portable lighting assembly.
[0019] In this design, the lead wire of the lighting head 45 is a telescopic threaded lead wire. The telescopic threaded lead wire passes through the horizontal sleeve 46 and the lead wire hole 47 to connect to the circuit board 22. The telescopic length of the lead wire is greater than the adjustable height of the lighting head 45 on the lighting chamber 49, facilitating use. This design uses a movable lighting head 45, which allows the test leads to accurate illumination in the dark, further improving work efficiency and preventing measurement accidents that could lead to inaccurate measurement results.
[0020] In this design, a rubber sleeve is fitted onto the rear rod of the battery compartment 2 of the pen body 3. This sleeve is used to protect the pen body.
[0021] The concealed probe head protective sleeve 6 in this design includes a horizontal cylindrical chamber 62 installed in a frustoconical part at the front of the pen body 3. A front through hole is provided at the front of the frustoconical part, and the diameter of the front through hole is larger than the diameter of the probe head shank. The front inner wall of the horizontal cylindrical chamber 62 is provided with internal threads to form a threaded front chamber. The rear end of the horizontal cylindrical chamber 62 expands outward evenly to form a limiting rear chamber for positioning. A protective sleeve 63 is provided inside the horizontal cylindrical chamber 62. The outer surface of the protective sleeve 63 is provided with external threads and is threadedly connected to the threaded front chamber. An annular limiting ring 64 is provided at the rear end of the protective sleeve 63, and the annular limiting ring 64 cooperates with the limiting rear chamber. An annular front cap 61 is provided at the front end of the protective sleeve 63.
[0022] In use, the user twists the annular front cap 61 with their fingers, causing the protective sleeve 63 to rotate. The outer surface of the protective sleeve 63 has external threads that connect with the threads of the threaded front chamber; therefore, the protective sleeve 63 can be unscrewed. When the annular limiting ring 64 reaches the front end of the limiting rear chamber, the protective sleeve 63 covers the probe head to provide protection. The protective sleeve 63 in this design is made of plastic material, which is both insulating and, due to the inherent strength of the plastic material, provides effective protection in the event of impact or drop.
[0023] In this design, the inner wall of the protective sleeve 63 is provided with a thin sponge layer or a flexible thin rubber layer for further protection of the probe tip.
[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
