The rack meshing with the gear follows the slider hinged to the horizontal rail to move, realizing the reciprocating movement of the positioning pin. The positioning pin is installed on the linear guide rail, with high positioning accuracy, convenient positioning, improved assembly efficiency, and better assembly effect. Description of the Drawings

[0010] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments recorded in the present application. For those of ordinary skill in the art, other drawings can be obtained without creative labor based on these drawings.

[0011] Figure 1The figure shows a perspective view of the guiding and positioning mechanism in a specific embodiment of the present utility model. Detailed implementation mode

[0012] Next, the technical solutions in the embodiments of the present utility model will be described in detail with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0013] Refer Figure 1 As shown, the guiding and positioning mechanism in this embodiment includes a bottom plate 1. A vertical plate 2 is fixed on the bottom plate 1. A longitudinal axis 3 is provided on the left side of the vertical plate 2. The longitudinal axis 3 is rotatably connected to the vertical plate 2. A horizontal rail 4 is fixed on the vertical plate 2 above the longitudinal axis 3. A slider 5 is slidably connected to the horizontal rail 4. A positioning pin 6 is fixed on the slider 5. The right end of the positioning pin 6 extends to the right side of the vertical plate 2. A swing arm 7 and a gear 8 are fixedly sleeved on the longitudinal axis 3. A rack 9 meshing with the gear 8 is transversely provided on the bottom surface of the slider 5. A cylinder 10 is hinged on the bottom plate 1. The end of the cylinder 10 not hinged to the bottom plate 1 is hinged to the swing arm 7.

[0014] Further, the longitudinal axis 3 is rotatably connected to the vertical plate 2 through a bearing seat 11.

[0015] Further, the cylinder 10 is hinged to the bottom plate 1 through a double-earring support 12.

[0016] In this technical solution, the guiding and positioning mechanism drives the swing arm to rotate through the hinged cylinder, and then drives the gear to rotate through the longitudinal axis. The rack meshing with the gear moves along with the slider hinged to the horizontal rail, realizing the reciprocating movement of the positioning pin. The positioning pin is installed on the linear guide rail, with high positioning accuracy, convenient positioning, improved assembly efficiency, and better assembly effect.

[0017] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0018] The above are only the specific implementation manners of this application. It should be noted that for those of ordinary skill in the art, without departing from the principle of this application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this application.
