[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0027] like Figure 1-9 As shown, the ultra-thin tension meter includes a tension meter head for installation in a meter case, the tension meter head includes an indication panel 1 and a back shell 2 connected to the indication panel 1, and the back shell 2 is provided with a conductive column 3 for wiring and a connection hole 4 arranged at the edge of the back shell 2;

[0028] The conductive column 3 includes a sleeve 31 and an elastic fixed column slidably arranged in the sleeve 31. The sleeve 31 is provided with a wiring hole 32 for wiring. A limiting mechanism 5 is arranged in the sleeve 31, so that when the elastic fixed column slides to the bottom of the sleeve 31, the elastic fixed column cooperates with the limiting mechanism 5 to reach the limit.

[0029] The ultra-thin wire tension meter includes a wire tension meter head, wherein the conductive column 3 of the wire tension meter head adopts a sleeve 31 and an elastic fixed column structure, and a limiting mechanism 5 is arranged inside the sleeve 31. When wiring is required, the elastic fixed column is slid upward, the wire is inserted into the wiring hole 32, and then the elastic fixed column is pressed down, so that the lower end of the elastic fixed column cooperates with the limiting mechanism 5 to achieve a limiting effect, and the wiring is firmly clamped; when it is necessary to remove, the elastic fixed column is operated to make the elastic fixed column detach from the limiting mechanism 5 to achieve removal. The ultra-thin wire tension meter of the utility model adopts an elastic pressing structure, which makes installation more convenient and connection more stable. At the same time, after pressing, the elastic fixed column is stored in the sleeve 31, which can make the structure of the wire tension meter head thinner.

[0030] The elastic fixing column includes a light column 33, an elastic member 34 disposed at the lower end of the light column 33, and a pressing head 35 connected to the elastic member 34. After the wiring enters the wiring hole 32, the light column 33 is pressed to make the elastic fixing column move downward as a whole, and after descending a certain distance, the pressing head 35 presses and compresses the wiring. In order to achieve stable compression of the wiring, the pressing head 35 is an inner concave arc surface 36, and the pressing end surface of the pressing head 35 is provided with a friction structure 37 to prevent the wiring from loosening.

[0031] The limiting mechanism 5 includes limiting protrusions 54 arranged on both sides of the light column 33, a first guide groove 51 axially provided on the inner side wall of the sleeve 31, a second guide groove 52 axially provided on the inner side wall and connected to the first guide groove 51, and a limiting portion 53 arranged at the end of the second guide groove 52. When the light column 33 is pressed down, the limiting protrusion 54 first moves in the first guide groove 51, then enters the second guide groove 52 by rotation and finally enters the limiting portion 53. Preferably, a fixed rib is provided at the upper end of the elastic fixing column, and a screwing groove 6 is provided at the center of the elastic fixing column.

[0032] In order to achieve smooth movement of the limiting protrusion 54 in the guide groove and stable cooperation with the limiting portion 53, the limiting portion 53 is semicircular and the protrusion is cylindrical to match the limiting column.

[0033] The thickness of the tension meter head of this embodiment is 15 mm, which is 5 mm less than the 20 mm of similar products on the market, making it ultra-thin and easy to install. It only needs to use a portable electric drill to directly open two Φ14 conductive column holes and open four Φ3 installation and fixing holes for installation and use. When wiring and removal, after the wiring enters the wiring hole 32, press the light column 33 to make the elastic fixing column move downward as a whole. After descending a certain distance, the top pressure head 35 presses and compresses the wiring. At this time, the light column 33 is rotated by screwing the groove 6 to rotate the light column 33, so that the limiting protrusion 54 enters the limiting part 53. Loosen the focus. At this time, under the action of the elastic member 34, the limiting protrusion 54 is stably limited in the limiting part 53 to achieve stable wiring.
