[0001] This utility model relates to the field of mortise and tenon processing, and in particular to an adjustable wooden toy mortise and tenon processing fixture. Background Technology

[0002] Wooden toys are toys made primarily of wood. In the process of making wooden toys, mortise and tenon joints are used to ensure that the various parts are tightly connected together. Mortise and tenon joints play a key role in connecting the various scattered wooden parts into an organic whole.

[0003] During the processing of mortise and tenon joints, clamps are needed to assist in positioning them to ensure that the length and width of the tenon, as well as the depth and diameter of the mortise, are accurately processed.

[0004] The existing technology has the following drawbacks: most traditional wooden toy tenon and mortise processing jigs are fixed by twisting the threaded rod. For example, when dealing with wooden tenons and mortises of different lengths and diameters, the fixing operation is relatively cumbersome and may require multiple large-scale twisting of the relevant parts to achieve the fixation. Therefore, an adjustable wooden toy tenon and mortise processing jig is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an adjustable wooden toy tenon and mortise processing fixture, which aims to improve the problem of cumbersome operation that requires frequent twisting of bolt rods in the prior art.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Referring to Figures 1-3, one embodiment of this utility model provides an adjustable wooden toy mortise and tenon processing fixture, including a connecting frame 1. The connecting frame 1, a movable plate 2, and a support frame 3 constitute the main body of the fixture. The movable plate 2 is slidably connected to the inner wall of the connecting frame 1. The support frame 3 is fixedly connected to the right end of the movable plate 2. The support frame 3 mainly supports and connects the threaded sleeve 4 and the threaded rod 5. The threaded sleeve 4 is fixedly connected to the inner wall of the support frame 3. The inner wall of the threaded sleeve 4 has a pattern that matches the threaded rod 5, which allows the threaded rod 5 to move along the threaded sleeve 4. The inner wall of the sleeve 4 is threaded with a threaded rod 5. The left end of the threaded rod 5 is rotatably connected to a rotating block 6. The rotating block 6 is made of rubber material, which can increase the friction with the wooden tenon and mortise. The inner wall of the connecting frame 1 is provided with a limit mechanism. The inner wall of the movable plate 2 is provided with a slot 9. The slot 9 has a horizontal opening and a vertical opening. The horizontal opening can meet the normal movement of the pressing rod 7 and the movable plate 2. The vertical opening corresponds to the protrusion on the outer wall of the pressing rod 7, allowing the protrusion to enter the vertical opening. The side wall of the connecting frame 1 is rotatably connected with a connecting block 10. The inner wall of the connecting frame 1 is provided with an adjustment component.

[0031] The limiting mechanism includes a pressing rod 7, the end of which has a protrusion that is the same shape as the vertical opening of the slot 9. The pressing rod 7 passes through and is slidably connected to the inner wall of the connecting frame 1. The connecting frame 1 has a slot corresponding to the pressing rod 7, which allows the pressing rod 7 to move along the slot. The inner side wall of the pressing rod 7 is elastically connected to the connecting frame 1 through a return spring 8.

[0032] Referring to Figures 1 and 4, the adjustment assembly includes a rod 12. The left end of the rod 12 is rectangular, and the rod 12 can be moved by flicking the rectangular part with a finger. The rod 12 is slidably connected to the inner wall of the connecting frame 1. The connecting frame 1 has a slot corresponding to the rod 12, which allows the rod 12 to move vertically along the connecting frame 1. A rotating shaft 11 is inserted into the outer wall of the rod 12. A groove is formed on the outer wall of the rotating shaft 11, which is the same shape as the rod 12, allowing the rod 12 to be positioned relative to it. A magnetic strip 13 is fixedly connected to the inner side wall of the rod 12. The rotating shaft 11 is fixedly connected to the left end of the connecting block 10. The bottom end of the magnetic strip 13 is in contact with the top end of the connecting frame 1. The top end of the connecting frame 1 has a magnetic plate corresponding to the magnetic strip 13. The rod 12 can be positioned by the attraction between the magnetic strip 13 and the magnetic plate. The rotating shaft 11 is rotatably connected to the inner wall of the connecting frame 1.

[0033] Referring to Figures 1-3, the inner side wall of the pressing rod 7 is fixedly connected to one end of the return spring 8. When the pressing rod 7 moves forward, it will compress the return spring 8. When resetting, the elastic force of the return spring 8 will carry the pressing rod 7 to reset. The other end of the return spring 8 is fixedly connected to the outer wall of the connecting frame 1. The pressing rod 7 is engaged in the inner wall of the slot 9.

[0034] Working principle: First, when clamping and fixing wooden tenons and mortises of different diameters, press the pressing rod 7 to move it forward, so that the end protrusion of the pressing rod 7 separates from the vertical opening of the slot 9. At this time, the return spring 8 is in a compressed state. Then, move the entire support frame 3 to the left, along the inner wall of the connecting frame 1 with the movable plate 2. The position of the rotating block 6 can be quickly adjusted for tenons and mortises of different lengths. Then, place the tenon and mortise between the connecting block 10 and the rotating block 6. By slightly rotating the threaded rod 5, the rotating block 6 contacts and fixes the wooden tenon and mortise. There is no need to twist the threaded rod 5 multiple times to fix wooden tenons and mortises of different sizes.

[0035] When the fixed wooden tenon and mortise needs to be adjusted in angle, simply flick the insert rod 12 with your finger to separate the magnetic strip 13 from the magnetic plate on the connecting frame 1. At the same time, the insert rod 12 separates from the outer wall groove of the rotating shaft 11. Rotating the rotating shaft 11 causes the connecting block 10, the wooden tenon and mortise, and the rotating block 6 to rotate. After the adjustment is completed, simply release the insert rod 12 with your hand to insert the insert rod 12 into the outer wall groove of the rotating shaft 11. The magnetic strip 13 and the magnetic plate on the connecting frame 1 attract each other to complete the positioning.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
