DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Please refer to Figure 1-5 A decorative rod center drilling device includes a support base 8 with an L-shaped longitudinal section, wherein the horizontal section of the support base 8 serves as the main processing platform of the device and can be fixedly connected to the workbench under normal conditions, and the vertical section of the support base 8 is used to connect to the installation shell 10 in the device.

[0025] Specifically, the device is provided with a connecting rod 3 inside the mounting shell 10, one end of the connecting rod 3 is located inside the mounting shell 10 and is rotatably connected to the mounting shell 10, and the other end of the connecting rod 3 protrudes out of the mounting shell 10 and is fixedly connected to a handle 2, which can facilitate the operator to rotate the connecting rod 3.

[0026] A corresponding through groove is opened in the middle section of the connecting rod 3, and a follower rod Ⅰ4 is inserted in the through groove. One end of the follower rod Ⅰ4 is rotatably connected to the connecting rod 3, and the other end of the follower rod Ⅰ4 is rotatably connected to the positioning plate 5. Therefore, under the action of gravity, the positioning plate 5 is located below the follower rod Ⅰ4. When the user rotates the connecting rod 3, the follower rod Ⅰ4 can be driven. At this time, under the action of gravity, the positioning plate 5 moves downward.

[0027] Therefore, the device has a hole-opening mechanism 6 fixedly connected to the lower end of the positioning plate 5. When the positioning plate 5 drives the hole-opening mechanism 6 to move downward, the decorative rod 7 placed on the upper side of the horizontal section of the support seat 8 can be hole-opened.

[0028] Generally, the hole-opening mechanism 6 includes a driving motor, and a drill bit is detachably connected to the lower end of the driving motor. The driving motor drives the drill bit to rotate at a high speed to realize the hole-opening operation.

[0029] Specifically, a notch groove 11 is provided at the center of the horizontal section of the support seat 8 to correspond to the hole opening mechanism 6 , so as to ensure that the hole opening mechanism 6 opens a through hole on the decorative rod 7 .

[0030] Specifically, the left and right sides of the horizontal section of the support seat 8 have a plane shape of a certain length, and the decorative rod 7 is supported by the planes on both sides.

[0031] Furthermore, the device is provided with a mounting frame 9 on the front and rear sides of the decorative rod 7, and each mounting frame 9 is fixedly connected with a positioning tenon 18 on the left and right sides respectively. The multiple positioning tenons 18 and the decorative rod 7 are in the same horizontal plane, so that the device can control the distance between the two positioning tenons 18 to achieve the abutment between the positioning tenons 18 and the decorative rod 7, thereby ensuring that the decorative rod 7 cannot change the height of the horizontal plane.

[0032] In order to control the distance between the two positioning tenons 18, that is, the two mounting frames 9, the device is rotatably connected with a positioning shaft 21 inside the support seat 8, and the two axial ends of the positioning shaft 21 are coaxially fixedly connected with a driving gear 16, and each driving gear 16 is respectively provided with a rack 17 on the upper and lower sides, so as to utilize the different meshing positions of the rack 17 and the driving gear 16 to achieve the purpose of controlling the two racks 17 to move toward or away from each other when the driving gear 16 rotates.

[0033] The device fixedly connects two racks 17 in the same horizontal plane to one of the mounting frames 9, thereby controlling the position of the mounting frame 9 through the racks 17, thereby achieving the purpose of controlling the distance between the front and rear positioning tenons 18 when the driving gear 16 is rotated.

[0034] At the same time, it should be emphasized that since the front and rear mounting frames 9 of the device can only make front and rear linear motions in completely opposite directions but with exactly the same distance under the drive gear 16, it is only necessary to set the center point of the line between the two mounting frames 9 and the center axis of the hole opening mechanism 6 to be in the same vertical plane in the initial state. In this way, the device can actually cope with any width of the decorative rod 7, and can also ensure that under the action of the front and rear positioning tenons 18, the center axis of the hole opening mechanism 6 and the center line of the decorative rod 7 are in the same vertical plane.

[0035] Specifically, Figure 4 As shown, the positioning tenon 18 of the device is projected into a triangular structure on the vertical plane. This form can use the inclined surfaces on the upper and lower sides of the positioning tenon 18 to further limit the decorative rod 7 in the upper and lower directions, ensuring that the decorative rod 7 will not move at all during the processing.

[0036] Furthermore, the device is also provided with a damping pad made of rubber material on the inner side of the positioning tenon 18, which increases the friction between the positioning tenon 18 and the decorative rod 7 to avoid relative movement, and can also use the deformable property of rubber to avoid deformation caused by rigid collision between the decorative rod 7 and the positioning tenon 18.

[0037] Furthermore, in order to reduce the number of operating steps and alleviate the burden on operators, the device is fixedly connected to a drive shaft 12 on the rear end face of the connecting rod 3. The drive shaft 12 is coaxial with the rotation position of the connecting rod 3 and the mounting shell 10. Therefore, in practice, the connecting rod 3 can be regarded as performing circular motion around the central axis of the drive shaft 12.

[0038] In the device, a rope wheel 20 is coaxially sleeved on the outer side of the positioning shaft 21, and a pull rope 13 is wound around the side end surface of the rope wheel 20.

[0039] One end of the pull rope 13 is fixedly connected to the rope wheel 20, and the other end of the pull rope 13 is fixedly connected to the drive shaft 12. That is, when the user rotates the connecting rod 3 to change the relative height of the positioning plate 5, the device can synchronously drive the positioning shaft 21 through the pull rope 13, that is, drive the driving gear 16 to change the distance between the front and rear positioning tenons 18, so that the hole opening and fixation are carried out synchronously, reducing the operating steps of the operator.

[0040] It should be noted that the middle section of the pull rope 13 of the device is embedded in the vertical section of the support seat 8. By opening a sliding groove for the pull rope 13 inside the support seat 8 to place the pull rope 13, the pull rope 13 is positioned to ensure that the pull rope 13 can achieve force transmission.

[0041] Furthermore, the device is provided with a clockwork spring 19 on the outside of the positioning shaft 21, the inner end of the clockwork spring 19 is fixedly connected to the positioning shaft 21, and the outer end of the clockwork spring 19 is fixedly connected to the support seat 8 so that through constraint, when the front and rear positioning tenons 18 move toward each other, the clockwork spring 19 is compressed by force, which makes it possible for the front and rear positioning tenons 18 to automatically move away from each other after the hole opening process is completed, thereby facilitating subsequent processing.

[0042] Furthermore, in order to ensure processing accuracy, an auxiliary rod 15 is arranged inside the installation shell 10 of the device. The auxiliary rod 15 and the connecting rod 3 are arranged symmetrically on the left and right, and the auxiliary rod 15 and the connecting rod 3 are respectively fixedly connected with half gears on the outer sides near the ends thereof, and the two half gears are meshed and transmittedly connected, so that when the user rotates the connecting rod 3, the half gears can be used to synchronously drive the auxiliary rod 15 to complete a motion process with exactly the same motion form.

[0043] At the same time, the device constrains the end of the auxiliary rod 15 fixedly connected to the half gear to be rotatably connected to the mounting housing 10, thereby ensuring that the distance between the auxiliary rod 15 and the connecting rod 3 satisfies the meshing connection relationship of the two half gears.

[0044] The device is provided with a follower rod II 14 at the other end of the auxiliary rod 15, one end of the follower rod II 14 is rotatably connected to the auxiliary rod 15, and the other end of the follower rod II 14 is rotatably connected to the positioning plate 5, so that the relative position of the positioning plate 5 is constrained by the cooperation between the auxiliary rod 15 and the follower rod, ensuring that the hole opening mechanism 6 can only make linear movements up and down at all times, avoiding the hole opening mechanism 6 from changing its horizontal position.

[0045] It should be noted that the device has corresponding receiving grooves on the support seat 8 for the rack 17 and the mounting frame 9 to avoid travel conflicts. The device constrains the rack 17 to abut against the support seat 8 at one end away from the drive gear 16. At this time, the rack 17 can be constrained and positioned by the support seat 8 and the corresponding receiving groove to ensure the stability of the connection between the rack 17 and the drive gear 16.

[0046] Therefore, the device is provided with a limit rod 1 at the upper end of the connecting rod 3, and the limit rod 1 is fixedly connected to the mounting shell 10. When the connecting rod 3 abuts against the limit rod 1, the rack 17 is meshed and transmitted with the corresponding driving gear 16, thereby preventing the rack 17 from separating from the driving gear 16.

[0047] At the same time, the existence of the limit rod 1 is also to ensure that the force applied by the clockwork spring 19 on the driving shaft 12 is sufficient to pull the connecting rod 3 to rotate upward and put the handle 2 in a position that is easy to hold.

[0048] Therefore, when the connecting rod 3 is in contact with the limiting rod 1 , the angle between the central axis of the gripping rod and the vertical plane is not equal to zero degrees. At this time, the user can pull the gripping rod 2 downwards more conveniently.

[0049] During the actual use of the utility model;

[0050] First, the user places the decorative rod 7 on the support base 8 and preliminarily determines that the decorative rod 7 is in a suitable position;

[0051] Afterwards, the user pulls the handle 2 downward, at which time the connecting rod 3 and the positioning shaft 21 rotate synchronously, the positioning plate 5 drives the hole opening mechanism 6 to move downward, and the positioning tenons 18 on the front and rear sides move toward each other;

[0052] Then, when the positioning tenons 18 on both the front and rear sides are in contact with the decorative rod 7, the hole-opening mechanism 6 is in contact with the upper end surface of the decorative rod 7. At this time, the handle 2 is continuously pulled downward, the damping pad inside the positioning tenon 18 is deformed, and the hole-opening mechanism 6 is embedded in the decorative rod 7 to complete the hole-opening operation;

[0053] Finally, the user releases the handle 2, the clockwork spring 19 is elastically released, the positioning tenon 18 is separated from the decorative rod 7, and the hole opening mechanism 6 moves upward.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
