The first benchmark 2 is connected with a second adjustment mechanism 5, and the second adjustment mechanism 5 is used to adjust the height of the second benchmark 3.
[0026] As Figure 3-5 shown, in order to adjust the height of the first benchmark 2, the first adjustment mechanism 4 includes a gear 401. A tooth groove 102 is provided in the installation shell 1, and the tooth groove 102 penetrates through the inner wall of the installation shell 1. The gear 401 is rotatably connected in the tooth groove 102 of the installation shell 1. The first benchmark 2 is slidably attached to the inner wall of the installation shell 1. A rack groove 203 is provided on one side of the first benchmark 2, and the gear 401 meshes with the rack groove 203. A connecting shaft 402 is fixedly connected to one side of the gear 401. The connecting shaft 402 rotatably extends out of one side of the installation shell 1. A rocker 403 is fixedly connected to the end of the connecting shaft 402. A fastener 404 is threadedly connected to the connecting shaft 402, and the outer wall of the fastener 404 is threadedly connected to one side of the installation shell 1. A first scale line 204 is provided on the outer side of the first benchmark 2. The installation shell 1 is symmetrically and fixedly connected with limit frames 101 up and down, and the first benchmark 2 is slidably adapted in the limit frames 101, thereby improving the stability of the lifting and sliding of the first benchmark 2.
[0027] As Figure 5-7As shown in the figure, in order to adjust the height of the second benchmark 3, the second adjustment mechanism 5 includes a screw 501. A chute 201 is provided in the first benchmark 2. The chute 201 penetrates through the upper end of the first benchmark 2. The screw 501 is rotatably connected in the chute 201. The second benchmark 3 is slidably fitted in the chute 201. A limit block 302 is fixedly connected to the outer periphery of the second benchmark 3. A limit chute 202 is provided on the inner wall of the chute 201. The limit block 302 is slidably fitted in the limit chute 202. The second benchmark 3 is threadedly connected to the screw 501. A fixed plate 205 is fixedly connected to the lower end of the first benchmark 2. The lower end of the screw 501 rotatably extends out of the fixed plate 205. A limit plate 502 is fixedly connected to the lower end of the screw 501. A limit ring 504 is fixedly connected to the upper end of the limit plate 502. A limit ring groove 206 is provided at the lower end of the fixed plate 205. The limit ring 504 is rotatably fitted in the limit ring groove 206.

[0029] When the present utility model is in use, the support mechanism 6 is fixed on the ground through the rivet 604. According to the height requirement of the benchmark for measurement, the rocker 403 is rotated to drive the connecting shaft 402 to rotate, and then drive the gear 401 to rotate. Through the meshing of the gear 401 and the rack groove 203, the first benchmark 2 is lifted and slid in the installation shell 1. The data can be directly read through the first scale line 204. If the maximum height of the first benchmark 2 does not meet the height requirement of the measurement, the push rod 503 is rotated. The push rod 503 is at the eccentric shaft of the limit plate 502, and then drives the limit plate 502 to rotate, and then drives the screw 501 to rotate. Under the limiting effect that the limit block 302 is slidably connected to the limit chute 202, the second benchmark 3 slides up in the chute 201. The corresponding measurement data can be obtained by combining the second scale line 301 with the first scale line 204.

Furthermore, the double-adjustment benchmark is used to meet different benchmark height requirements. The support mechanism 6 facilitates the fixed support of the benchmark on the ground.
