In some embodiments, as shown in fig. 2 to 4, the fixing base 11 has a first boss 111 and a second boss 112 arranged at an interval, the sliding member 12 has a connecting portion 122, and the connecting portion 122 is sandwiched between the first boss 111 and the second boss 112. When the sliding member 12 slides relative to the fixing base 11, the connecting portion 122 moves back and forth between the first boss 111 and the second boss 112, and the connecting portion 122 is limited between the first boss 111 and the second boss 112 to slide along the arc-shaped track.

In a specific embodiment, as shown in fig. 1, 3 and 4, specifically, the surfaces of the first boss 111 and the second boss 112 facing each other are respectively attached to two opposite sides of the connecting portion 122. A plurality of positioning grooves 121 are formed in the connecting portion 122 along an arc-shaped track of the slider 12 (i.e., along a track indicated by an arrow F in fig. 4), and the positioning assembly 13 is mounted on the first boss 111. Thus, in an initial state, the positioning element 132 is clamped in a positioning slot 121, when the sliding element 12 slides relative to the fixing base 11, the connecting portion 122 moves relative to the first boss 111, during the moving process, the connecting portion 122 pushes against the positioning element 132, the positioning element 132 extrudes the elastic element 131, the elastic element 131 elastically contracts to enable the positioning element 132 to be disengaged from the current positioning slot 121, and along with the sliding of the sliding element 12, when the positioning element 132 moves to face another positioning slot 121, the elastic element 131 elastically extends and pushes the positioning element 132 into the positioning slot 121 facing the positioning element 132.

Thus, the positioning element 132 can be inserted into the positioning slot 121 when protruding relative to the first mounting hole 1111 and can slide out of the positioning slot 121 when being retracted relative to the first mounting hole 1111, so that the elastic element 131 and the positioning element 132 are disposed without interfering with the movement of the sliding element 12.

In this embodiment, as shown in fig. 2 and 3, the positioning element 132 is a ball, such as a steel ball or a glass ball with a certain structural strength, the ball is roll-mounted in the first mounting hole 1111, and the elastic element 131 is a spring, so that when the sliding element 12 slides relative to the fixing base 11, the connecting portion 122 pushes the ball to roll, so that the ball can smoothly slide into or out of the positioning slot 121.

Further, as shown in fig. 3 and 4, the positioning groove 121 is configured to have a shape and a size suitable for the ball, so as to ensure that the ball can be just inserted into the positioning groove

In a specific embodiment, as shown in fig. 4, along the arc-shaped track of the sliding member 12, the positioning grooves 121 are uniformly spaced, so that the sizes of the grooves of the positioning grooves 121 are equal, the distance of the positioning member 132 moving between the sliding members 12 is equally divided, that is, the sliding radian of the sliding member 12 is also equally divided, and when two adjacent positioning grooves 121 are infinitely close to each other, the distance between the centers of two adjacent positioning grooves 121 can be reduced as much as possible, at this time, the moving radian of the positioning member 132 sliding between two adjacent positioning grooves 121 corresponding to the sliding member 12 is relatively small, thereby facilitating the fine adjustment of the angle.

It is understood that in other embodiments, a plurality of positioning slots 121 may also be disposed on the first boss 111 along the arc-shaped track of the slider 12, and correspondingly, the positioning assembly 13 is mounted on the connecting portion 122, i.e. the first mounting hole 1111 is disposed on the connecting portion 122.

The principle is the same as the above embodiments, and the detailed description is omitted here.

In other embodiments, as shown in fig. 1, 3 and 5, the connecting portion 122 abuts against a surface of the second boss 112 facing the first boss 111, the second boss 112 is provided with a second mounting hole 1121, and the stopper 14 is mounted in the second mounting hole 1121 and can move telescopically along an axial direction of the second mounting hole 1121; when the stopper 14 is in the locked state, one end of the stopper 14 facing the connecting portion 122 extends out of the second mounting hole 1121 to abut against the connecting portion 122, and at this time, the stopper 14, the first boss 111, and the positioning element 132 clamp the connecting portion 122 from two sides of the connecting portion 122, so as to limit the sliding of the slider 12. When the stopper 14 is in the unlocked state, the stopper 14 is retracted into the second mounting hole 1121, the stopper 14 is disengaged from the connecting portion 122, and the connecting portion 122 can be forced to slide.

In a specific embodiment, as shown in fig. 3 and fig. 5, the connecting portion 122 is sequentially provided with a plurality of stopping grooves 1221 along an arc-shaped track (i.e., a track indicated by an arrow F in fig. 5), the plurality of stopping grooves 1221 correspond to the plurality of positioning slots 121 one to one, and when the positioning element 132 is clamped in one positioning slot 121, the end of the stopping element 14 can be correspondingly inserted into one stopping groove 1221. That is, each time the positioning member 132 moves from one positioning groove 121 to another positioning groove 121, correspondingly, the end of the stopper 14 toward the connecting portion 122 also moves from one stopping groove 1221 to another stopping groove 1221, thereby enabling the stopper 14 to better limit the slider 12.

In this embodiment, as shown in fig. 2 and 4, the angle adjusting mechanism 10 of this embodiment further includes a locking handle 142 and a stop spring 143, the stop member 14 is a fastening member 141, such as a bolt or a screw, the second mounting hole 1121 is a threaded hole, the fastening member 141 is screwed into the second mounting hole 1121, the fastening member 141 moves along the axis of the second mounting hole 1121 so that the end portion facing the connecting portion 122 extends or retracts relative to the second mounting hole 1121, so that the end portion of the fastening member 141 is inserted into the stop groove 1221 or is pulled out of the stop groove 1221, thereby switching the stop member 14 between the locked state and the unlocked state. An end of the fastening member 141, which is away from the connecting portion 122, extends out of the second mounting hole 1121 and is used for mounting the locking handle 142, and in use, a user can hold the locking handle 142 and rotate the fastening member 141, so that the fastening member 141 moves along the axial direction of the second mounting hole 1121, and the stopping member 14 is switched between the locking state and the unlocking state.

Further, a sunken platform 1123 is arranged at the position of the second mounting hole 1121, which is away from the opening of the connecting portion 122, and the stop spring 143 is clamped between the sunken platform 1123 and the locking handle 142, or a step portion 1411 may be arranged at the end of the fastening member 141, which is away from the connecting portion 122, and the stop spring 143 is clamped between the sunken platform 1123 and the step portion 1411. Thus, when the stopper 14 is in the locked state, the stopper spring 143 is in the elastically compressed state, and at this time, the stopper spring 143 applies an elastic pushing force to the locking handle 142 or the fastening member 141, which is directed away from the connection portion 122, so as to increase the frictional force between the fastening member 141 and the hole wall of the second mounting hole 1121, thereby improving the connection stability and reliability of the fastening member 141, and thus stabilizing the slider 12 shown in the fixing base 11.
