[0034] The ruler base 10 is provided with a slide rail 110 , a screw matching hole 120 , a hanging hole 130 and a matching inclined surface 140 .

[0035] The slide rail 110 is used to connect the ruler body 20 and cooperate with the corresponding structure on the ruler body 20 to achieve a slidable connection. The slide rail 110 includes a track body 1110 and a limiting groove 1120, and the limiting groove 1120 is arranged at the bottom of the track body 1110.

[0036] The screw fitting hole 120 is used to fix the pointer component 40 .

[0037] The hanging hole 130 is used for hanging or carrying the tool ruler.

[0038] The matching inclined surface 140 is used to cooperate with the corresponding structure on the ruler body 20 to limit the sliding range of the ruler body 20 .

[0039] The ruler body 20 is provided with a slide groove 210 , a pointer groove 220 , a threaded through hole 230 , a main scale surface 240 , a secondary scale surface 250 , a main scale line 260 , a secondary scale line 270 , a clamping head 280 and an inclined surface 290 .

[0040] The slide slot 210 is used to cooperate with the slide rail 110 on the ruler seat 10 to realize the slidable connection between the ruler body 20 and the ruler seat 10. The slide slot 210 includes a slide slot body 2110 and a limiting edge 2120, and the limiting edge 2120 is arranged at the opening of the slide slot body 2110.

[0041] The pointer groove 220 is used to accommodate the pointer component 40 and to form a limit block for the pointer component 40 through the end of the groove body.

[0042] The threaded through hole 230 is used to cooperate with the locking component 30 to fix the sliding position of the ruler body 20 on the ruler base 10 .

[0043] The main scale surface 240 and the sub-scale surface 250 are used to set the main scale lines 260 and the sub-scale lines 270 respectively.

[0044] The clamping head 280 is disposed at the end of the ruler body 20, and the extending direction of the clamping head 280 is perpendicular to the extending direction of the ruler body 20. The end surface of the ruler base 10 is used to form a dimension measuring structure similar to a vernier caliper.

[0045] The inclined surface 290 is used to cooperate with the matching inclined surface 140 on the ruler base 10 , so that the matching inclined surface 140 can form a limiting blocking effect on the sliding range of the ruler body 20 .

[0046] The locking component 30 includes a hand-turned cap 310 and a screw portion 320 ; the hand-turned cap 310 and the screw portion 320 are integrally formed.

[0047] The pointer component 40 includes a fixing portion 410 and an indicating stop portion 420; the fixing portion 410 and the indicating stop portion 420 are integrally formed, and the extending direction of the indicating stop portion 420 is perpendicular to the fixing portion 410. The fixing portion 410 is provided with a fixing hole 430.

[0048] Assembly relationship:

[0049] The ruler body 20 is slidably disposed on the ruler base 10 through the cooperation between the slide rail 110 and the slide groove 210. The track body 1110 is disposed in the slide groove body 2110, and the limiting edge 2120 is disposed in the limiting groove 1120. Under the cooperation between the limiting groove 1120 and the limiting edge 2120, the ruler body 20 can only slide forward and backward on the track body 1110, and cannot move in the lateral direction, that is, in the direction perpendicular to the ruler base 10 and the ruler body 20, thereby avoiding the separation of the ruler body 20 and the ruler base 10 in the lateral direction.

[0050] The pointer component 40 is fixed to the ruler base 10 through the cooperation of the fixing hole 430, the screw matching hole 120 and the screw 50. The indicating limiter 420 of the pointer component 40 is slidably disposed in the pointer groove 220. In this way, when the ruler body 20 slides on the ruler base 10 along the track body 1110, the end of the pointer groove 220 can form a blocking limit on the sliding range of the ruler body 20, thereby preventing the ruler base 10 and the ruler body 20 from separating in the longitudinal direction, that is, the sliding direction.

[0051] The screw part 320 of the locking component 30 is disposed in the threaded through hole 230. By tightening the hand-turned cap 310, the ruler body 20 can be fixed on the ruler base 10 for convenient reading. By loosening the hand-turned cap 310, the ruler body 20 can be loosened for the size measurement operation.

[0052] Technical effect:

[0053] 1. The tool ruler with vernier caliper function disclosed in the present application, when there is no relative sliding between the ruler base 10 and the ruler body 20, the locking component 30 locks and fixes the ruler body 20 on the ruler base 10, and at this time the inclined surface 290 is closely matched with the inclined surface 140, and can be used as a general tool ruler. When the vernier caliper function is needed, the locking component 30 is loosened, and the ruler body 20 slides along the slide rail 110 on the ruler base 10, and a vernier measurement structure can be formed through the ruler base 10 and the ruler body 20, so that the tool ruler can be used as a general tool ruler or a vernier caliper.

[0054] 2. The tool ruler with the function of a vernier caliper disclosed in the present application can limit the lateral separation of the ruler body 20 and the ruler base 10 through the cooperation of the upper limit groove 1120 of the slide rail 110 and the upper limit edge 2120 of the slide groove 210; and can limit the longitudinal separation of the ruler body 20 and the ruler base 10 through the cooperation of the indicating limit portion 420 of the pointer component 4- and the end of the pointer groove 220; so that the overall structure of the tool ruler is compact, the connection is reliable, and it is resistant to falling and bumping, and has good practicality and durability.

[0055] The technical scheme and technical effects of the present application are described in detail above in combination with the drawings and specific embodiments of the specification. It should be noted that technicians in this field can also develop other embodiments on this basis; any simple deformation and equivalent substitution that does not deviate from the innovative concept of the present application are covered by the present application and belong to the scope of protection of this patent.
