According to a preferred embodiment, the tendency of the angular detent mechanism 20 to move towards the longitudinal extension of the strut 1 is released in such a way that the telescopic mechanism 17 is allowed to move relatively towards the ground on the basis of the height of the bottom end of the leg 18 from the ground when the button 19 is in the first operating position, on application of an external force thereto, and the angular detent mechanism 20 locks the angle between the leg 18 and the longitudinal extension of the strut 1 in such a way that the partial extension of the telescopic mechanism 17 is allowed to remain and the leg 18 is relatively fixed to the strut 1 when the button 19 is in the second operating position, corresponding to the first operating position, on application of an external force thereto.
Preferably, the first operating position corresponds to a position in which the free end of the button 19 is pulled up to disengage it from the top end of the holder, and the second operating position corresponds to a position in which the free end of the button 19 is pushed down to be fixedly connected to the top end of the holder. This allows the pole 1 to be opened by the button 19 from the folded closed position to the erected open position when the prism assembly is to be installed by the practitioner, allowing the pole to be folded up minimally without taking up too much space, as the telescoping mechanism 17 is telescoped within the leg 18 when the pole 1 is not in use. When it is desired to use the bar 1, the practitioner releases the retraction mechanism 17 via the button 19, facilitating the bar 1 to stand upright on the ground, and at the same time adjusting the spacing between each leg 18 to allow the bar 1 to rest stably. Preferably, the leg 18 and the bracket 16 are rotatably connected with each other, the telescopic mechanism 17 is slidably connected with the leg 18 according to a chain arranged in the leg, when the free end of the button 19 is pressed to a position fixedly connected with the top end of the bracket, the free end is fixedly connected with the top end of the bracket 16 according to a mode of limiting the relative rotation between the leg 18 and the bracket 16, meanwhile, the bottom surface of the button 19 abuts against the telescopic mechanism 17, and as shown in fig. 4, an engaging piece arranged on the bottom surface of the button 19 can be fixedly connected with the chain according to a mode of limiting the telescopic mechanism 17 to continuously extend and retract. When the free end of the button 19 is pulled up to be disconnected from the top end of the bracket, the supporting legs 18 can be reset to the vertical state in a relative rotation manner with the bracket 16, the telescopic mechanism 17 is contracted and expanded into the supporting legs 18 in a manner that a coil spring arranged at the end part of the chain releases elastic potential energy, and the telescopic mechanism 17 is fixed relative to the supporting legs 18 when the free end of the button 19 is pressed down again.
According to a preferred embodiment, when the stand 16 is in the folded closed position, the button 19 is able to release its free end, which is snap-connected to the top end of the stand 16, from the top end of the stand 16 by applying an external force to it, and thus to disengage the bottom surface of the button 19, which is snap-connected to the telescopic mechanism 17, from the telescopic mechanism 17, so that the user can manually open the leg 18 to an angle with the longitudinal extension of the bar 1 and to extend the leg 18 to a distance from the bottom end of the bar 1, and wherein the transition of the stand 16 from the folded closed position to the erected open position is achieved by applying an external force to the button 19 to return the button 19 to the first operative position.
According to a preferred embodiment, when the support 16 is in the support-opened state, the button 19 is capable of releasing the free end thereof, which is in snap connection with the top end of the support 16, from the top end of the support 16 by applying an external force to the button so as to disengage the bottom surface of the button 19, which is in snap connection with the telescoping mechanism 17, from the telescoping mechanism 17, as shown in fig. 2, so that the leg 18, which is opened to a certain angle with the longitudinal extension direction of the strut 1, gradually contracts towards the longitudinal extension direction close to the strut 1 under the action of a first component of its own weight, and the telescoping mechanism 17 achieves the transition of the support 16 from the support-opened state to the folded-closed state in a manner of allowing the telescoping mechanism 17 to contract under the action of a resultant force formed by a second component of its own weight and a supporting force provided to the support-closed state by the ground, wherein the first component is a component of its own weight of the telescoping mechanism 17 in a direction perpendicular, the second component force is a component force of the self-gravity of the telescopic mechanism 17 in a direction parallel to the supporting leg 18, that is, after the use of the measuring staff is finished, the free end of the button 19 is only required to be pulled up, and the automatic storage of the support 16 can be realized under the action of the self-gravity of the telescopic mechanism 17.
