[0033] And the marking operation can be carried out through the marking assembly 4 during measurement, and the light supplement operation can be carried out through the lamp strip 5, so that the detection and measurement in multiple environments and multiple situations are satisfied.

[0034] The utility model further sets up that: the main ruler 1 includes a ruler seat 13 and a ruler body 14, the ruler seat 13 is provided with a light outlet 131 that communicates with the assembling groove 12, the light outlet 131 is provided with a light transmission plate 132, and the ruler body 14 is detachably installed at the light outlet 131.

[0035] The utility model further sets up: the ruler body 14 is made of transparent plastic board. The design of this structure can built-in lamp area 5, cooperate on transparent or translucent material, make inside light can irradiate outward, so that the operator is convenient for seeing the value on the ruler body 14.

[0036] The lamp area 5 and power component are prior art, and the lower end of the main ruler 1 can be provided with a USB plug hole for charging the power component, and the power component can be a battery and a control board.

[0037] The utility model further sets up: the marker assembly 4 includes rotating head 41, telescopic piece 42 and operating head 43, and rotating head 41 and operating head 43 are arranged at both ends of telescopic piece 42 respectively, and operating head 43 is provided with an operating port along one side of the width direction of main ruler 1.

[0038] Operating head 43 includes a brush piece 6 movably installed inside.

[0039] The utility model further sets up: rotating hole is arranged in the mounting groove 11, both ends of rotating head 41 are provided with rotating arm 411, and rotating arm 411 is rotatably connected in the rotating hole. Figure 2 As shown in the figure, through the cooperation of rotating hole and rotating arm 411, the marker assembly 4 can be circumferentially rotated, so that the required marking function is met.

[0040] The utility model further sets up: telescopic piece 42 includes fixed rod 421, telescopic rod 422 and elastic sleeve 423, sliding groove 424 is arranged on fixed rod 421, telescopic rod 422 is slidably connected in sliding groove 424, elastic sleeve 423 is arranged in sliding groove 424 and located between telescopic rod 422 and fixed rod 421.

[0041] The design of this structure can make telescopic rod 422 effectively stay in a certain length area when pulling telescopic rod 422 through the interference fit formed by elastic sleeve 423, so that the required condition is met.

[0042] Because the structure adjustment cannot be accurately realized, other existing telescopic rod 422 cooperation structures can be used according to specific use requirements, which will not be described here.

[0043] The utility model further sets up: brush piece 6 includes pen seat 61, pen head 62 and return spring 63, pen seat 61 is slidably connected in operating head 43 through return spring 63, pen head 62 is detachably installed at one end of pen seat 61 close to the operating port.

[0044] Pushing part 64 is arranged on pen seat 61 and protrudes from operating head 43.

[0045] As shown in the design of this structure, when the pushing part 64 is pressed, the pen holder 61 drives the pen tip 62 to move upward Figure 4 towards the upper direction, so as to extend out from the operation port to achieve marking operation, and compress the return spring 63. When the pushing part 64 is not pressed, the pen holder 61 is reset under the action of the return spring 63. Figure 4

[0046] The present utility model is further configured that: a pressing block 65 is threadedly connected to the pushing part 64.

[0047] The moving stroke of the base can be specifically controlled by the following two conditions: 1. The compressible degree of the return spring 63; 2. The pressable length of the pushing part 64.

[0048] Taking Solution 2 of this structure as an example, the diameter length dimension of the pressing block 65 is greater than the diameter length dimension of the pushing part 64. Since when the pressing block 65 abuts against the operating head 43, it is the longest moving stroke of the pen holder 61 (the stroke of the return spring 63 is greater than the pressable length of the pushing part 64).

[0049] Therefore, the benefits that can be brought by adjusting through the pressing block 65 are: the maximum extension amount of the pen tip 62 can be changed. When the extension amount of the pen tip 62 is limited, the pen tip 62 abuts against the side wall of the operation port, so as to ensure the stable connection between the pen tip 62 and the pen holder 61.

[0050] When the moving stroke of the pushing part 64 is increased by rotating the pressing block 65, the installation area of the pen tip 62 and the pen holder 61 can be exposed outside the operating head 43, and at this time, the replacement operation of the pen tip 62 can be carried out.

[0051] When the installation area of the pen tip 62 and the pen holder 61 is inside the operation port, the replacement of the pen tip 62 cannot be carried out.

[0052] The present utility model is further configured that: a connecting part with an "丄" - shaped structure is arranged on the pen holder 61, and an abutting edge is arranged inside the operating head 43. The abutting edge and the connecting part enclose an "工" - shaped structure for installing the return spring 63. As Figure 4 described, the design of this structure can facilitate the installation of the return spring 63.

[0053] The above is only the preferred implementation mode of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
