As a further aspect of the present invention: the rotating component comprises a handle, a screw rod, a connecting shaft and an annular protruding part arranged on the outer wall of the connecting shaft.

As a further aspect of the present invention: a circular hole is formed in the position, aligned with the screw hole, of the movable seat.

As a further aspect of the present invention: the bottom of stopper has seted up the hole groove, the first half of hole groove is semi-circular, and the latter half uses circular tangent point downwardly perpendicular to extend.

As a further aspect of the present invention: the external thread of the outer wall of the screw rod is meshed with the internal thread of the inner wall of the screw hole.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through setting up rotatable parts, when adjusting the removal seat position, for the bolt fastening mode, it is more swift, can effectively improve work efficiency, be difficult to produce simultaneously not hard up, avoid the fracture position because of removing the not hard up slow problem of recovery that leads to of seat.

In the figure: 1. a connecting arm; 2. a connecting seat; 3. a movable seat; 4. a limiting block; 5. a rotating member; 6. a limiting groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, in an embodiment of the present invention, a wrist support includes: a connecting arm 1 with a sliding groove formed at the top end; the bottom end of the movable seat 3 is provided with a protruding part, and the protruding part of the movable seat 3 is connected with the inner cavity of the sliding groove in a sliding manner; the connecting seat 2 is sleeved in the moving seat 3, and a through screw hole is formed in the connecting seat 2 along the X axis; the rotating part 5 is arranged at one end of the connecting arm 1, penetrates through the sliding groove and is in threaded connection with the screw hole; a limiting groove 6 formed at the top end of the connecting arm 1 and extending downwards and positioned at one side of the sliding groove; and the limiting block 4 is clamped in the inner cavity of the limiting groove 6.

In this embodiment: when adjusting removal seat 3, through rotatory rotating part 5, rotating part 5 can rotate, can remove about this moment and rotating part 5 through threaded connection's connecting seat 2, remove the in-process about, drive and remove the seat and remove, can carry out accurate position control.

Please refer to fig. 1, the rotating member 5 includes a handle, a screw, a connecting shaft, and an annular protrusion disposed on an outer wall of the connecting shaft; the bottom of stopper 4 has seted up the hole groove, and the first half in hole groove is semi-circular, and the latter half uses circular tangent point downwardly perpendicular to extend.

In this embodiment: when the rotating part 5 is installed, because one end of the connecting arm 1 is provided with the through hole, the screw section of the rotating part 5 is firstly inserted from the through hole at one end of the connecting arm 1, because the vertical section of the through hole is of the convex-shaped structure, the annular protruding part at the end of the connecting shaft is contacted with the step surface of the through hole, the limiting block 4 is clamped into the inner side of the limiting groove 6 at the moment, the hole groove at the bottom end of the limiting block 4 can be matched with the step surface of the through hole to limit the protruding part, and therefore the rotating part 5 is limited.

Please refer to fig. 1, a circular hole is formed at the position of the movable seat 3 aligned with the screw hole; the external thread of the outer wall of the screw rod is meshed with the internal thread of the inner wall of the screw hole.

In this embodiment: the setting of circular port can be so that rotating member 5 runs through and removes seat 3, avoids removing seat 3 and produces and hinder the interference effect, and secondly when the screw rod rotates, connecting seat 2 removes under its internal thread's effect.

The above-mentioned, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
