The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0027] Embodiment 1:

[0028] Please pay attention to Figures 1 to 5 A grating ruler comprises a ruler body 1 and a ruler head 2 slidably mounted on the front end of the ruler body 1, a control line 21 is arranged on the ruler head 2, a plug connector 22 is arranged at the other end of the control line 21, a winding line assembly 3 is arranged outside the control line 21, two groups of L-shaped metal snap plates 11 are symmetrically arranged on the rear wall of the ruler body 1, a fitting assembly 4 is arranged at the rear end of the ruler body 1, and the ruler body 1 is detachably connected to the fitting assembly 4 through the metal snap plates 11.

[0029] Specifically, the winding wire assembly 3 can adaptively retract and release the control wire 21 to prevent the control wire 21 from becoming scattered when the ruler head 2 slides. The metal snap plate 11 and the fitting assembly 4 can conveniently install the ruler body 1 at the corresponding position of the machine for use, without the need to open screw holes on the machine for installing the ruler body 1.

[0030] Please pay attention to Figure 5Preferably, the winding wire assembly 3 includes a winding box 31, the inner wall of the winding box 31 is rotatably connected to a hollow winding frame 32, a winding spring 33 is arranged inside the winding frame 32, and the control wire 21 can be wound on the outside of the winding frame 32, and the winding spring 33 can wind up the winding frame 32, thereby achieving the purpose of winding up the control wire 21.

[0031] The front and rear walls of the winding box 31 are symmetrically provided with inwardly recessed rotating grooves 311, and the outer wall of the winding frame 32 is symmetrically provided with rotating blocks 321 rotatably installed in the rotating grooves 311. This design enables the winding frame 32 to rotate inside the winding box 31.

[0032] The left and right walls of the winding box 31 are symmetrically provided with wire outlets 312 , and the inner wall of the wire outlet 312 is designed to be arc-shaped. This design can ensure that the control wire 21 is not damaged when the control wire 21 is retracted or released.

[0033] The bonding component 4 includes a bonding plate 41, the rear wall of the bonding plate 41 is a bonding surface, and a diaphragm 42 is provided on the bonding surface. The design of the bonding surface enables the bonding plate 41 to be bonded to the machine for use without opening screw holes on the machine for installing the ruler body 1.

[0034] A strip seat 43 is disposed on the left end surface of the bonding plate 41 , and a clamping seat 431 is disposed on the other end of the strip seat 43 . The clamping seat 431 can be clamped between the symmetrically arranged metal buckle plates 11 . This design can connect the upper ruler body 1 .

[0035] The upper and lower end surfaces of the clamping seat 431 are symmetrically provided with inwardly recessed mounting holes 432, a metal spring 433 is provided in the mounting hole 432, and a clamping head 434 is provided at the other end of the metal spring 433. The metal spring 433 can push the clamping head 434 outward so that the clamping head 434 is stably clamped in the clamping hole 12.

[0036] The symmetrically arranged metal snap plate 11 is provided with an inwardly recessed snap hole 12 at one end close to the snap head 434, and the snap head 434 can be movably installed in the snap hole 12. This design restricts the installed metal snap plate 11, thereby achieving the purpose of stably installing the ruler body 1.

[0037] It should be noted that the ruler body 1 and ruler head 2 of the present embodiment are technical means well known to those skilled in the art. The specific connection and control sequence should refer to the following working principle. The electrical connection is completed in the order of working between the electrical components. The detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0038] The specific operation method of the utility model is as follows: when installing, first determine the installation location on the machine platform, then tear off the diaphragm 42, stick the adhesive surface of the bonding plate 41 on the machine platform, wait for a period of time to allow the adhesive surface to solidify, then align the metal snap plate 11 of the ruler body 1 with the left side of the strip seat 43 and the clamping seat 431, and then push the ruler body 1 in the direction close to the strip seat 43 and the clamping seat 431 to make it installed on the outside of the strip seat 43 and the clamping seat 431 (as the ruler body 1 is pushed, the metal snap plate 11 will squeeze the clamping head 434, so that it squeezes the metal spring piece 433 toward the installation hole 432 and shrinks in the installation hole 432, until the two sets of metal snap plates 11 are aligned and clamped in the strip seat 43 and the clamping seat 431, the metal spring piece 433 is no longer squeezed, and the clamping head 434 is pushed outward, so that the clamping head 434 is clamped in the clamping hole 12 to stabilize the ruler body 1, and the installation is completed);

[0039] After installation, connect the plug connector 22 to the power supply and controller for use. When in use, the ruler head 2 is energized to perform corresponding data measurement. As the ruler head 2 slides in the direction away from the winding box 31, the control line 21 will be pulled outward. At this time, the winding frame 32 will also rotate synchronously, and the winding spring 33 will make a stretching action. As the ruler head 2 slides in the direction close to the winding box 31, the winding spring 33 will make a contraction action and start to wind up the winding frame, thereby achieving the function of winding up the control line 21 and avoiding the control line 21 from being scattered.

[0040] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
