In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

The contents of the present invention will be further described in detail with reference to the specific embodiments, and fig. 2 shows a schematic structural view of the middle and double-side adjustable cervical spine tractor of the present invention, which is composed of a front-neck split body 1 and a back-neck split body 2, which are used in cooperation with each other to fit the contour of the neck of the human body. In addition, in order to adjust the opening and closing angle of the chin support frame 12 relative to the chest support frame 11, two sets of adjusting mechanisms 13 (shown in fig. 3) are symmetrically arranged on the side surface of the neck front split body 1, and each adjusting mechanism 13 includes a sliding member 131, a lifting rod 132 and a locking member 133 for limiting the position of the sliding member 131. One end of the lifting rod 132 is hinged to the sliding member 131, and the other end thereof is hinged to the chin support frame 12. The glide 131 is freely slidably attached to the chest support frame 11 (as shown in fig. 4). Thus, a connecting rod force applying mechanism is formed among the chest support frame 11, the chin support frame 12 and the lifting rod 132, and when the opening and closing angle of the chin support frame 12 needs to be adjusted, only the sliding member 131 needs to be moved, and then the lifting rod 132 is driven to push the chin support frame 12 to rotate around the fixed point. Compared with the traditional angle adjusting mechanism, the technical scheme can ensure that the adjusting process is more labor-saving, the state stability after adjustment is higher, and the slippage phenomenon is not easy to occur.

As a further optimization of the above bilateral adjustable cervical vertebra tractor, a strip-shaped through groove 111 can be specifically formed on the chest support frame 11, and saw-toothed limiting protrusions 1111 are uniformly distributed on two side walls of the chest support frame. The sliding member 131 slides along the strip-shaped through slot 111 and includes two locking legs 1311 extending in the same direction. A hooking portion 13111 (shown in fig. 6) adapted to the saw-toothed stopper protrusion 1111 is provided at a free end of the catching pin 1311. Correspondingly, long waist-shaped protrusions (as shown in fig. 7) for increasing the included angle between the locking legs 1311 are provided on the bottom surface of the locking member 133. When the opening and closing angle of the chin support frame 12 needs to be adjusted, the relative opening and closing angle of the chin support frame 12 is first enlarged by pushing the slide 131 and by the force transmission action of the lift lever 132 until a predetermined angle is reached. One hand of the operator always applies force to the sliding member 131 to keep the relative position of the sliding member 131 unchanged, and at the same time, the other hand of the operator pushes the locking member 133 to move towards the sliding member 131 until the long kidney-shaped protrusion enters between the two clamping legs 1311, and then the two clamping legs 1311 move back to back until the hooking part 13111 arranged on the outer side surface of the long kidney-shaped protrusion sinks into the saw-toothed limiting protrusion 1111, so that the relative position of the sliding member 131 is kept unchanged (as shown in fig. 8). It should be noted that the expansion portion 1331 for achieving the above-mentioned expansion function of the locking leg may be designed into other structures according to specific shapes, besides the long waist-shaped projection.

Further, the expanding portion 1331 is inserted between the two locking legs 1311 smoothly. It is also necessary to provide a clamping guide 1332 on the locker 133, which comprises two clamping legs 13321 extending outwardly along the locker 133 and always abutting elastically against the side walls of the runner 131. Along its extension, both clamping feet 13321 are inclined toward one another, so that during the insertion of the expansion 1331 into the clamping foot 1311, the clamping foot 13321 always bears against the side wall of the slide 131, so that a directed displacement of the locking element 133 is achieved. As a further optimization, the clamping feet 13321 may be extended in length and provided at their ends with opposed arcuate projections 133211. When the expanding portion 1331 expands the clamping leg 1311, the arc-shaped protrusion 133211 goes over the end of the sliding member 131, so as to achieve the fixed connection between the locking member 133 and the sliding member 131, and further achieve the locking of the relative position of the sliding member 131 (as shown in fig. 9).

Further, a hinge shaft hole 121 may be formed at the chin rest 12 to correspond to a hinge shaft provided at an end of the lift lever 132. The number of hinge shaft holes 121 is provided in plural and distributed in a linear array, thereby facilitating adjustment of the number of power trains of the jack rod 132 according to the circumstances.

In order to improve the convenience of operation, friction increasing portions including a plurality of anti-slip protrusions arranged thereon may be further provided on the pressing surfaces of the slide 131 and the locker 133 in a linear array.

As known, the existing cervical vertebra tractor can produce extrusion and wearing phenomenon to the human chest in the in-service use process, along having influenced experience sense, in order to solve this problem, pastes lining elasticity chest welt 3 on the interior table wall of the lower tip of body 1 before the neck, specifically can select for use the plastic rubber material. By analogy, the free end of the upper part of the neck back split body 2 can be set to be the outward turning arc-shaped surface 23, and the elastic protection pad (not shown in the figure) is attached to the outward turning arc-shaped surface 23, so that the fitting degree of the neck back split body 2 and the cervical vertebra is improved, the cervical vertebra muscle is prevented from being extruded, and the use comfort is improved.

Furthermore, a tightening belt 4 is also arranged on the bilateral adjustable cervical vertebra tractor. The neck back split body 2 is provided with a plurality of strip-shaped through holes 21 for the tightening belts to pass through. A male magic tape 41 is provided at the free end of the tightening band 4, and correspondingly, a female magic tape 14 is fixed on the front split body 1 of the neck. Therefore, the relative distance between the front neck split body 1 and the rear neck split body 2 can be adjusted conveniently, and the operation is very convenient. Besides the above mentioned fastening form of hook and loop fastener, the present invention can also be used in the form of lock catch and hook.

Finally, a through slot may be provided in the posterior cervical spine 2 to form a vertebral body abutment 22 in a central region thereof (as shown in fig. 5). The vertebral body joint part 22 has a certain degree of freedom relative to other areas, and is provided with a strip-shaped through hole 21 for the tightening belt 4 to pass through, so that the back neck split body 2 is conveniently and accurately jointed with the cervical vertebra of a human body, and therefore, on one hand, the force required for tightening the tightening belt 4 can be greatly reduced, and the convenience of tightening operation is improved; on the other hand, can also carry out accurate application of pressure to human cervical vertebra, improve medical effect.
